Canadians Can Be Unruly, See For Yourself

Some of my favourite tax scholarship steps outside technical detail and speaks to how tax systems promote or are informed by higher-order values. So, I welcome Shirley Tillotson’s magnificent and richly researched new book on the era between the enactment of Canada’s federal income tax law in 1917 and its heady 1960s reform period, which saw taxpayer-citizens actively debating the contours of democracy through the vehicle of tax reform. At its heart, the book is about what we can learn about democracy from our engagement with taxation and how our democracy can be enhanced when we find ourselves talking about taxes over coffee.

A historian could learn a lot about tax history from reading iterative drafts of legislation, department of finance notes, house of commons debates, and parliamentary committee reports: indeed, some have. Tillotson doesn’t take those as her starting place. Instead, she is interested in how “real people” engage with the tax system and its reform. For her book, she culled through thousands of letters between taxpayers and tax authorities. The letters were mined from the records of the Department of Finance and the Department of National Revenue, in the papers of prime ministers, finance ministers, opposition leaders, and tax officials.

She displaces the myth that tax rage or revolt are new phenomenon. Her work documents a range of complaints about the tax system and proposed reforms over 50 years; yet, there was change in that period. No one could contest that what started as a perhaps more modest (and elite-focused) project had become a mass tax. Perhaps her work offers us hope that in the face of resistance and complaint there is the potential for dialogue, adjustment, compromise, and ultimately, transformation.

Tillotson is a beautiful writer, and often funny, a pleasant surprise. And so, her work is worth reading in its entirety for pleasure alone. Nevertheless, as a teaser for a largely American Jotwell readership, she also draws out some of the American tax story. For example, before the Second World War, Canada relied more heavily on regressive taxes than the United States, and was appealing to wealthy Americans seeking to reduce their government contributions. Although Americans adopted a marital income splitting approach to tax unit, Canada resisted (despite some strong advocacy to follow suit). Canada has lacked the constitutional-style tax resisters often found in the US, although Tillotson’s book certainly documents the stroppiness of the Canadian public when it comes to tax policy and tax reform. Hence the unruly title of this Jot.

Let me end with a brief aside. One of the things I appreciate in the work of others is their willingness to engage with scholarly colleagues and to acknowledge the contributions of others. Tillotson has worked closely over the years with a Canadian colleague, Elsbeth Heaman. (Heaman also published a tax history book in 2017 – Tax, Order, and Good Government: A New Political History of Canada, 1867 – 1917 (2017). Tillotson gracefully and regularly acknowledges — both in this work, but also in her interviews and media work on it — the joy and value of having had a thoughtful collaborator in the pursuit of Canadian tax history.

Tillotson’s book is a fine contribution to tax and social history. If you are an American wondering how tax dialogue works in the big piece of land to the North, it’s well worth your time.

What Do Audits Teach Us About Tax Compliance?

For those interested in understanding taxpayer compliance—including what motivates taxpayers to report honestly and how to reduce tax evasion – there is a robust body of empirical and legal literature. A number of economists and lawyers have examined the effect of traditional deterrence mechanisms like audits and penalties, as well as non-economic factors like social norms, guilt, taxpayer attitudes about how their tax money is spent, and other psychological factors. While this growing body of literature provides a rich description of the myriad of factors that influence tax compliance decisions, our understanding of taxpayer behavior is far from complete, and further study continues to be necessary. In expanding our understanding of taxpayer motivations, one revealing but possibly overlooked resource is the IRS Taxpayer Advocate Service (“TAS”), which each year publishes a number of empirical studies and other reports relevant to tax compliance. The authors of TAS studies are uniquely situated in that they have access to IRS tax return data, which should provide the best evidence of how taxpayers make decisions in the real world.

As part of the Taxpayer Advocate’s most recent Annual Report to Congress, the TAS published Audits, Identity Theft Investigations, and Taxpayer Attitudes: Evidence from a National Survey (the “Report”). The Report surveyed 2,729 Schedule C filers, that is, taxpayers reporting income from self-employment. Of this group, roughly half (1,363) had been previously audited and half (1,366) had not. One of the primary goals of the Report was to examine how audits influence taxpayer attitudes and behavior. While several of the findings are predictable and consistent with other research on audits, three of the Report’s findings are quite surprising.

The first and most surprising finding is that nearly 40 percent of the audited taxpayers surveyed did not know they had been audited. You read that right. When audited taxpayers were asked if they had been audited in the past, a significant number of them (38.7 percent) did not appear to realize they had been. Why? The answer is at least partly in the details. Taxpayers who experienced a “correspondence audit” (in the form of letters from the IRS) were far more likely to not realize they were being audited compared to those who experienced an in-person audit. It’s plausible that taxpayers envision audits as involving an IRS agent digging through their files, and that they simply do not perceive an exchange of letters as an audit. But since more than 70 percent of audits are done through correspondence, perhaps audits don’t have as strong of a deterrent effect as we might assume.

The second surprising finding is that audited taxpayers have more favorable views about justice in the tax system than non-audited taxpayers. Specifically, audited taxpayers perceive higher levels of procedural justice, informational justice, interpersonal justice, and distributive justice as compared to unaudited taxpayers, perhaps indicating that their experience with the IRS was “transparent, respectful, and appropriate” according to the Report. On the one hand, this may indicate that the IRS gets a bad rap: we might assume an audit will be an invasive and stressful experience when, in actuality, perhaps it’s not so bad. On the other hand, less than half of taxpayers surveyed owed the IRS money after their audit, and nearly 19 percent were owed a refund. This happy and perhaps unexpected outcome likely influenced the attitudes of some survey respondents.

The third surprising finding is that taxpayers who receive a refund after an audit have less favorable views about the tax system than those who receive no adjustment after an audit. In fact, taxpayers with no change after an audit reported the highest perceived levels of distributive justice in the tax system and most positive attitudes overall as compared to taxpayers who owed money and those who were owed a refund. Interestingly, this indicates that post-audit refunds don’t necessarily promote positive attitudes towards the IRS and the tax system. Perhaps the explanation here is that an audit with no adjustment indicates that everything was working correctly: the taxpayer got it right on her return and IRS inquiry did not change the result. On the other hand, it is somewhat surprising that taxpayers who got their returns right the first time aren’t more resentful that they were audited at all, especially as compared to those who receive a surprise refund.

Other aspects of the Report were not surprising. Self-employed taxpayers tend to consider cheating more than employed taxpayers, which makes sense because the former group has significantly more opportunity to cheat. It is also unsurprising that taxpayers who owed money after an audit report more negative attitudes about the tax system compared to those who weren’t audited, including lower levels trust in the IRS and higher levels of anger.

Overall, there are a number of possible takeaways from the Report. Audits appear to have a deterrent effect, but we may overestimate their power given the number of taxpayers who don’t realize they have been audited. At the very least, we can’t necessarily analyze the impact of audits collectively, as the type of audit (correspondence versus in-person) matters a great deal. Furthermore, the IRS’s bad reputation—at least when it comes to audits—might be undeserved, given the positive attitudes reported by many audited taxpayers. More generally, the Report highlights the fact that taxpayer attitudes about the tax system are heterogeneous and complex, underscoring the importance of continued study. Finally, the Report illustrates the wealth of information on tax compliance that is available thanks to TAS.

What We Now Know We Didn’t Know about Tax Evasion (and Why it Matters)

Annette Alstadsæter, Niels Johannesen & Gabriel Zucman, Tax Evasion and Inequality, NBER Working Paper No. 23772 (2017).

Over the past several years, a series of leaks related to offshore tax avoidance and evasion (SwissLeaks, LuxLeaks, the Panama Papers, Bahama Leaks, and Paradise Papers, to name a few) has fueled calls for tax transparency. To date, most discussion of the leaks has been policy-oriented (leaks: good or bad?) and largely anecdotal (based on some truly outrageous revelations). It was not until very recently, however, that a small group of researches started delving into the data exposed by these leaks to make statistically significant empirical findings. Alstadsæter, Johannesen & Zucman’s (AJZ) paper is an excellent example of such paper, which combines methodological sophistication, public data, and leaked data, to make important new contributions to the voluminous literature on the offshore tax world.

Matching leaked data with data from random audits in Scandinavian countries, public wealth records in those countries, and data from voluntary disclosure programs, AJZ find that offshore tax evasion (meaning, the act concealing income from tax authorities in offshore accounts), is not evenly distributed across wealth groups. Rather, they demonstrate that “the probability to hide assets offshore rises sharply with wealth, including within the very top groups of the wealth.”

AJZ findings stand in sharp contrast to what is known (or at least assumed) about tax evasion from stratified random audits, which—per AJZ— is “the key source used so far in rich countries” to study tax evasion. AJZ argue that random audits miss large part of tax evasion, “because it assumes that detected and undetected forms of tax evasion are similarly distributed across the income spectrum”. They suggest, however, that “sophisticated forms of evasion involving legal and financial intermediaries—that are only accessible to wealthy taxpayers—are unlikely to be uncovered in random audits.”

AJZ find, however, that “[Scandinavian] households who own around $10-12 million in net wealth are twice more likely to conceal assets abroad than households with around $5-6 million; households with more than $45 million are four times more likely.” Consider another example: random audits suggest that the average evasion rate in Scandinavian countries is 3% (meaning, about 3% of all individual taxes are evaded in Scandinavia). AJZ find, however, that the top 0.01% of Scandinavian households (in terms of net wealth) evade about 25% of their income through offshore accounts. This stands in sharp contrast to the average 3% benchmark.

These findings are profound in many important ways. It means, for example, that models for assessing the tax gap (meaning, the amount of uncollected taxes) probably understate the tax gap, if such models usually assume even distribution of detected and undetected tax evasion among income groups. If undetected evaded income is concentrated at the top, it also means it should have been taxed at higher rates than previously assumed for purposes of calculating the gap. The findings also mean that standard measures of inequality severely understate the level of inequality, because such models rely on reported data, which by definition does not include unreported income, which—we now know—is concentrated within top-earning households.

In their paper, AJZ address the effects of their findings on inequality and the tax gap at length. But several other important themes—some more implicit—emerge. First, consider the fact that in Scandinavian countries tax compliance is a cultural trait. What might be the outcomes in economies where tax avoidance (and evasion) have a more favorable public view, such as the United States? AJZ indeed note that because other economies “own much more wealth offshore than Norway, the results found in Scandinavia are likely to be lower bounds for these countries.” Second, another important theme relates to the data on which we rely in tax policy making. Proposed legislation, enforcement actions, and administrative guidance all rely on modeling, which in turn rely on reported tax data. The AJZ paper at least raises a plausible argument that the entire tax-policy making process relies on severely faulty (if not incorrect) data. Finally, the AJZ paper emphasizes how leaks may affect our tax system, and point to the role of civil protest in tax. For years, policy makers and taxpayers invested significant effort in protecting taxpayers’ privacy, sometime legitimizing the offshore system as a protector of legitimate privacy concerns. These arguments make some sense in theory. But when 95% of the accounts identified in the leaks are not reported to tax authorities (as AJZ find when trying to match the leaked accounts with required reports on offshore accounts), the legitimacy of the privacy argument is diminished. It really seems that, for the most part, intermediaries in secrecy jurisdictions main function is to facilitate tax evasion and other illicit activities.

In a utopian world, we would not need to rely on leaks to provide the information needed to prescribe successful tax policies. But in this world, the AJZ paper suggests that leaks may play a helpful role in pushing us towards better tax policy. It is the leaks (and the data exposed in papers such as AJZ’s paper) that have driven recent changes in international tax law (such as the adoption of the common reporting standards and the automatic exchange of information by multiple countries). It is difficult to understate how profound has been the effect of leaks, and the following public outcry, on real tax policy. It is truly a bottom-up legal change.

There is a lot more to like in the paper, and I cannot hope to discuss it all in the confined space of this review. I will just note one of my favorite aspects: AJZ develop a model showing that after disclosing tax evasion in an amnesty program, tax evaders do not then find legal ways to avoid taxes. This suggests that discovered tax evasion is not substituted by “legal” tax avoidance, which means that anti-evasion enforcement action are efficient.

To summarize, AJZ’s paper is an early one among several others that use recent leaked data to try to empirically assess what we didn’t know we didn’t know about offshore tax evasion. The implications are profound and should guide data-driven tax policy making for the foreseeable future.

 Who Gets Taxed When a US Corporation Pays Dividends?

Steven M. Rosenthal and Lydia S. Austin, The Dwindling Taxable Share Of U.S. Corporate Stock, Tax Notes 923 (May 16, 2016).

The Dwindling Taxable Share Of U.S. Corporate Stock, written by Steven M. Rosenthal and Lydia S. Austin, analyzes the available data regarding the ownership of corporate stock in the United States. Over the history of the income tax, most business capital has been invested in corporations, so an assumption that the income taxation of business meant income taxation of corporations was a reasonable assumption. Similarly, most owners of domestic capital were assumed to be taxable individuals.

One could, therefore, use as a starting point for any reform proposal, the idea that a corporation would be taxed at the stated corporate rates and would make distributions of earnings to individuals who would be taxed at the stated individual rates. Rationalization of business taxation has often aimed at eliminating the incentive to engage in business investment other than through corporate entities. This rationalization (or “integration”) using these standard assumptions about the nature of corporate holdings, involves pushing the corporate tax out to shareholders (by effectively reducing rates when corporate income is distributed), or pushing the individual tax into corporations (by effectively reducing the rate on dividends received).

As many involved in the realpolitik of tax reform in the last decade appreciate, this easy starting point is no longer available. Although corporations continue to be registered in increasing numbers, and start-up enterprises continue to use them, free-standing corporations are now far less likely to either be the direct holders of productive assets or to be directly held by taxable individuals. Corporations are now much more likely to be minority shareholders in noncorporate entities, are more likely to be held by ownership chains that no long involve 80% control (the prerequisite to aggregation of entities into single entities for tax purposes) and, as Rosenthal and Austin demonstrate, more likely to have shareholders that are not taxable individuals.

The authors have set out to unpack the actual nature of the shareholder side of corporate taxation. Although it has been acknowledged for many years that not all shareholders are subject to tax on their corporate holdings, the prevailing assumption has been that most shareholders are, and thus that the earnings on capital invested through US corporations are, absent some sort of sophisticated tax planning, subject to two levels of tax. Reform has meant designing taxes such that the combination of the tax on corporations and the tax on shareholders is no more than the tax on investment made without the use of the corporate form.

Rosenthal and Austin review the work of others and the statistical reports in the Financial Accounts reported by the Federal Reserve. They conclude that a relatively low proportion of corporate holdings are subject to such double taxation. Their conclusion is that something just less than 25% of corporate entities are owned by taxable individuals. The biggest difference in the approach of Rosenthal and Austin involves disaggregating the Federal Reserve classification of “households” into nontaxable and taxable holders. Much of the nontaxable holdings are in pension plans and other preferred tax savings vehicles.

Rosenthal and Austin’s work complicates the task of rationalizing the corporate income tax. The challenge of the tax reformer becomes not simply developing a scheme that equates the taxation of returns to corporate equity with the returns made through other legal entities, but also determining which of the varied patterns of shareholder taxation should be preserved. This, in turn, requires determining whether the inducements intended when these patterns were created should be preserved, even if it means there may be no US tax imposed on some returns.

Rosenthal and Austin presented their work primarily to address the integration debate. Their work provides support for those who would push shareholder taxes in (even if this means eliminated some shareholder preferences) rather than pushing corporate taxation out, and relying on shareholder taxation. But their work has done something equally important, in showing how little we actually know about the taxation of business income. They did not attempt to unpack the corporate side of the historical assumptions. But it prompts a series of questions including the extent of investment made entirely outside of corporate entities, and the amount of investment made nominally through corporate entities but which is in fact under the control of entities in partnership with such corporations. These corporate-side questions present equivalent challenges to old assumptions about the nature of business taxation.

Rosenthal and Austin have made the work of those analyzing the taxation of business income in the US much harder. But that is a good thing, if it results in a disruption of the old approaches to integration and corporate reform more generally.

Cybersecurity and Tax Information: A Vicious Cycle?

Michael Hatfield, Cybersecurity and Tax Reform, 93 Ind. L.J. (forthcoming Spring 2018) available at SSRN.

The international tax arena is awash with calls for tax transparency, and a variety of reforms are underway at the national, regional and global level to bring such transparency to fruition. See, e.g., Joshua Blank’s recent article The Timing of Tax Transparency, reviewed by Omri Marian earlier this year. Of course, with great caches of information comes great potential for security breaches of all types. Michael Hatfield, in his forthcoming article, Cybersecurity and Tax Reform, draws attention to the immensely important cybersecurity risks and challenges of a tax system founded on government collection and use of significant quantities of information. Quoting a former FBI Assistant Director, Hatfield describes IRS taxpayer information as “the gold standard” for being a “treasure trove of information” from the perspective of cyber criminals—large quantities of very valuable data housed in one agency. Is the IRS ready? Maybe not.

Hatfield’s solution to these cyber risks (given the operational demands of running a tax system and the constraints faced by the IRS) is substantive law reform and not merely more security. To be clear, security is a great idea, but at some point, reality must step in and when it does, Hatfield argues that it points to a remedy grounded in tax design and not just cybersecurity. His bold proposal—to have the tax system collect less data—relies on the marriage of substantive law changes and a rethinking of the sources of data security.

To make his case, Hatfield begins by painting a somewhat discouraging picture of technology at the IRS. The IRS was an early adopter of computer technology in the 1960s, but it did not stay on the cutting edge. Hatfield offers a nuanced and rich understanding of why the IRS has had difficulty keeping pace with new technology and increasing demands on computerization in the ensuing decades. He points to a mix of factors including: (1) inadequate funding for the scale of the task (given the complex nature of IRS work, the volume of data, and the need to interface with the public); (2) inability to recruit and retain cybersecurity experts (with competition from not only the private sector but also from other government agencies such as NSA, the Pentagon, and the White House, which as Hatfield suggests, may have more “mission” appeal than the IRS); (3) too many users (including both IRS employees as well as taxpayers, third party information reporters, and tax professionals); and (4) the inherent challenges of cybersecurity.

What is interesting in light of its less-than-stellar cybersecurity/technology is that the IRS has not suffered a catastrophic cyberattack or breach to date. In an odd twist, Hatfield contends that the outdated technology at the IRS has served as a partial barrier to cybersecurity attacks. However, the pressure for the IRS to modernize remains strong. Technological innovation is viewed as the path by which the IRS can improve collection of taxes owed. There is also pressure to turn the tax compliance process into the online experience demanded by members of Congress and the public. These constituents have come to expect full online access and service based on their private sector experiences with ordering goods and services, managing bank accounts, and paying and processing credit cards online. In the face of pressure to modernize, Hatfield remains less than sanguine about IRS success on the technical battleground of cybersecurity.

Instead, Hatfield suggests that Congress seriously embrace a goal of collecting less information. He draws on a number of contemporary tax reform proposals to demonstrate ways in which some of them could systematically reduce the quantity and variety of information required and the number of individuals interacting with the tax system. One example he highlights is Pay-As-You Earn (PAYE)—a system of withholding through the year that would adjust withholding to ensure that the net amount withheld matches the taxpayer’s overall tax liability. The result would be no refund and possibly no tax return—at least assuming certain other simplifying tax law changes accompany PAYE, such as a reduction in the number of credits and deductions, fewer tax rates, and a diminished role of family status in individual taxation.

Hatfield offers this and other examples to illustrate his broader argument that Congress can and should tackle the challenge of cybersecurity in the tax system through a new approach to tax legislation. Specifically, he urges Congress to add cybersecurity impact to the usual list of criteria according to which tax legislation is judged (revenue, efficiency, equity, administrability, and political viability). Thus, Congress would consider whether proposed tax legislation would reduce the quantity and types of data collected and would consider such a reduction a point in favor of a particular rule. Hatfield makes a compelling case for the need to minimize the collection problem by having less data in the first place, rather than relying on raw technology and security to protect tax information. But he appreciates the tradeoffs that such an approach would entail in terms of accuracy, precision, equity, and the tax system’s ability to meet non-revenue goals (e.g., redistribution, business incentives, etc.).

There may be another reason that limited-information tax regimes may be difficult for the IRS to implement: cybersecurity risks from the private sector and from foreign governments. Across the globe, tax leaks (including leaks of data gathered in hacks of financial institution customer data) have highlighted notable gaps in tax laws, tax enforcement and tax compliance. The public and legislatures are now regularly confronted with information suggesting ways in which social, political and economic elites have engaged in tax evasion or tax avoidance. In response, international pressure has mounted for increased tax transparency and disclosures to governments. The goal is to have governments directly collect the useful information that tax leaks have been providing. It is possible that we may find ourselves trapped in a cycle in which cybersecurity risks emanating from the private sector and foreign governments create pressure on the IRS to obtain more information, which then generates cybersecurity risks associated with growing government data repositories. It is unclear whether Congress would be willing to affirmatively reduce information collection to break the cycle. But, as Hatfield argues effectively, it is an option Congress needs to take seriously.

Beyond the “Tax Loophole” Rhetoric

Heather Field, A Taxonomy of Tax Loopholes, 55 Houston L. Rev. (forthcoming 2018), available at SSRN.

One of the many obstacles in the way of productive governance these days is people talking past each other. In the tax context, for instance, everyone seems to agree that we need to “simplify” the tax system and eliminate “tax loopholes.” But, people with very different agendas mean very different things when they use these loaded terms. And using the loaded terms, without elaboration, interferes with our ability to engage in serious policy conversations.

In A Taxonomy for Tax Loopholes, Heather Field identifies this phenomenon and attempts to push us beyond the “tax loophole” rhetoric. She explores the different ways that the term “tax loophole” is used, provides a framework that is designed to promote more transparent substantive debate, and uses her framework to bring greater clarity to contemporary debates about specific tax issues. While, as Field acknowledges, the term “tax loophole” is not going away any time soon, her approach nonetheless brings refreshing incisiveness to a discourse that is too often clouded by meaningless labels.

Field’s most radical move is arguing that we should stop using the “tax loophole” label altogether. She explains that, unlike other difficult-to-define terms like “tax shelter” and “tax expenditure,” classifying something as a “tax loophole” has no actionable consequences. Rather, the term “tax loophole” simply reflects the labeler’s subjective dislike of a particular outcome, and thus it is fruitless to perseverate about what is, or is not, a “tax loophole.”

Having cleared away the distracting classification issue, Field argues that we should use a more robust framework for expressing the dissatisfaction that underlies the use of a “tax loophole” label. This framework should include: the normative policy objection (such as a concern regarding revenue, fairness, efficiency, complexity, or social policy) and a declaration of who is responsible (such as Congress, the President, Treasury, IRS, courts, or private parties). At bottom, Field’s framework is a call to replace the tax “‘loophole’ label’s appeals to emotion with appeals to logic and analysis.” (P. 29.) The hope is that identifying the problem, who is responsible, and what can be done about it, can lead to substantive, actionable debate.

Beyond offering a taxonomy, Field illustrates how it can be used to improve analysis regarding particular tax provisions and to better understand perceptions of the tax system. She explores how greater analytical precision regarding the commonly decried carried interest “tax loophole” offers a number of concrete reform options, as well as barriers to such reforms. And, most interestingly in my view, she explores the use of the “tax loophole” label by major news organizations leading up to the 2016 election. In so doing, she uses elements of her taxonomy to tease out the organizations’ real, underlying concerns for what they label to be “tax loopholes.” Her findings include, for example, that more liberal news sources focused much more on fairness concerns regarding “tax loopholes,” whereas more conservative news sources focused much more on economic concerns regarding “tax loopholes.” She suggests that this coverage mirrors Clinton voters’ focus on inequality and Trump voters’ focus on the economy. From these and other findings, Field hypothesizes that the liberal and conservative media’s divergent discussions regarding “tax loopholes” may both have reflected and perpetuated the increasing polarization exhibited in American culture and on the political stage.

While Field seems well aware that the Article is unlikely to result in the banishment of the term “tax loophole,” she ends with the hope that this effort nonetheless may help us move beyond the echo chamber that increasingly comprises our understanding of tax policy issues. I sincerely hope that she is right. And, in that vein, Field’s article will hopefully not only enrich tax policy discussions, but also underscore an important role for academics, which extends well beyond the tax field. By deploying their training in the manner that Field has done in this Article, academics can offer an alternative to a national dialogue that is increasingly, and worryingly, comprised of buzzwords that merely serve to confirm what people already think.

When the Life of the Law is Logic

Sarah B. Lawsky, Formalizing the Code, 70 Tax L. Rev. 377 (2017), available at SSRN.

In Formalizing the Code, Professor Sarah Lawsky offers a glimpse of what might be gained if law were written in formal logic language. It might be written by machine-language specialists attached to Congressional tax-writing committees. It could reduce unintentional ambiguity and complexity. Computers could understand it.

Lawsky takes as her focus a problem she calls definitional scope, defined as “when the Code uses a term but the structure of the Code leaves unclear to what a term refers.” (P. 378.) Definitional scope is about cross-references, and cross-references are one element of the formal structure of the Code.

Two examples that illustrate definitional ambiguity run through the paper. One is the question of whether the definition of “acquisition indebtedness” limits IRC Section 163(h)’s mortgage interest deduction with respect to a primary mortgage to debt of $1 million. Another is an ambiguity about the application of the so-called 50% ownership test to “a series of” corporate stock redemptions for purposes of the substantially disproportionate redemption rule of IRC Section 302(b)(2).

Lawsky shows how the discipline of translating statutory code into formal logic would identify ambiguities like those in Sections 163(h) and 302(b)(2). In the case of the definition of acquisition indebtedness, she proposes a logical formula that defines debt eligible for the mortgage interest deduction in terms of three elements labeled “Purpose,” “Secured” and “Amount.”  Once definition is structured this way, “[t]he statute cannot be formalized without resolving” whether a $1 million limitation is part of the definition of acquisition indebtedness. (P. 401.)

Lawsky advances two reasons for formalizing the code: increased certainty and decreased complexity. The discipline of logic that she proposes can help reveal instances of obscurity and ambiguity in the Code. In both of the examples presented, it is reasonable to think that if only Congress realized that its words were confusing, it would correct the problem quickly and easily. The uncertainty and complexity are not intentional. They are mistakes, which can be discovered with tools of formal logic, so that Congress can do what it meant to do in the first place.

In the examples that Lawsky presents, I agree. Congress often intends to write an ex ante rule, but trips itself up inadvertently. I also agree with her that a prescription for formalizing the code should leave room for intentional ambiguity.  As she explains, ambiguities could be presented as “alternate formalizations” or drafters could choose not to formalize an ambiguous point of law. (P. 399.)

One interesting question is whether rule drafters reliably know whether a provision should or should not be ambiguous.  What about the definition of “primary residence” in Section 163(h)?  Does it mean an RV, a boat, a yurt, a permanently orbiting spaceship?  What sorts of partial interests in property does it include?  Does a correct decision about the ambiguity of “primary residence” require not only that the drafters know about home ownership, but also that they appreciate the extent and limit of their knowledge?

This paper, like other recent examples of Lawsky’s work (here and in A Logic for Statutes, 21 Fla. Tax Rev. (forthcoming 2017) considers the potential of computer logic and artificial intelligence to transform law. The idea of formalizing the code is powerful and provocative. It shows how machine logic could identify and prevent human error. It also raises the issue of when formal logic can capture the meaning of law, and when it cannot.

The Most Significant Proposed Change in the History of U.S. Corporate Taxation

Alan Auerbach, Michael P. Devereux, Michael Keen & John Vella, Destination-Based Cash Flow Taxation (Oxford Ctr. for Bus. Tax'n, Working Paper No. 17/01, 2017).

The House Republican Blueprint for corporate tax reform would replace our century-old corporate income tax, which we all know and love (or hate), with a “destination-based cash flow tax” (DBCFT), which for many of us remains a mystery. The academic foundation upon which the House proposal is built is a working paper by Alan Auerbach (UC Berkeley), Michael Devereux (Oxford), Michael Keen (IMF), and John Vella (Oxford) (collectively “the authors”), entitled “Destination-Based Cash Flow Taxation.” Given the current turmoil in Washington, it seems unlikely that a DBCFT will be enacted any time soon. Problems with our current system for taxing business income with an international dimension, however, are unlikely to go away on their own. If you want to get up to speed on a radical solution with substantial academic and political support, this paper is an absolute must-read.

The DBCFT has two components: a cash flow tax, which alters the timing and sometimes the substance of includibility and deductibility, and the destination-based “border tax adjustments” that have already found their way (sometimes incoherently) into the popular press.

As to the first, the most obvious difference between cash flow and income taxation is that under a cash flow tax capital assets are expensed, not depreciated. As E. Cary Brown teaches us, expensing has the effect of taxing normal returns to capital at an effective rate of zero. Leverage can then drive effective rates of tax negative. See Theodore P. Seto, Federal Income Taxation: Cases, Problems And Materials 263-75 (2d ed. 2015). The authors do not view taxing returns to capital at an effective rate of zero as a disadvantage; consistent with optimal tax theory, they call it “neutrality.”

What happens next depends on whether the jurisdiction implements an R (real) or R+F (real plus financial) tax base. “Under the R base, transactions involving financial assets and liabilities are ignored – so, for example, interest receipts would not be taxed and interest expenses would not be deductible.” (P. 9.) “By contrast, under the R+F base, all cash inflows, including borrowing and the receipt of interest, would be taxable; all cash outflows, including lending, repaying borrowing and interest payments would be subtracted in calculating the tax base.” (P. 10.)

The House Republican Blueprint adopts a hybrid: interest is not deductible but borrowings are not includible. What this means, however, is that a taxpayer can zero out any tax liability, anytime, simply by borrowing (not includible) and using the proceeds to buy a capital asset (fully expensible). I understand that the most recent House implementation (not publicly available) attempts to limit this form of arbitrage by denying expensing for land and inventory, but can see many ways around this clearly inadequate bandaid.

The second part of a DBCFT, the so-called “border tax adjustments,” are not adjustments at all. The unfortunate label refers instead to the fact that a DBCFT is “based on sales of goods and services in the country less expenses incurred in the country.” (P. 14.) Revenues derived and expenses incurred outside the taxing jurisdiction are neither includible nor deductible. As a result, revenues from imports are taxed on a gross basis – no deductions are allowed for the offshore costs of production. And exports are heavily tax-subsidized – domestic costs of production are deductible but the resulting revenues are not includible.

You may be forgiven if your first reaction is that this sounds like the kind of import tariff/export subsidy system that many believe helped trigger the Great Depression. The authors postulate that currency markets would respond by making the dollar more valuable, exactly offsetting the tariff/subsidy-type effects of the tax. The net effect, they argue, would be trade neutrality. If so, this would represent a significant improvement over the current U.S. system, which penalizes domestic production by exempting foreign production profits from current taxation.

Overall, the authors assert, “[t]he DBCFT has several highly attractive properties: it does not distort the scale and location of investment, assures neutral treatment of debt and equity as sources of finance, is robust against avoidance through inter-company transactions, and provides long term stability due to its incentive compatibility and its resistance to tax competition among states. The DBCFT thus addresses many of the ailments afflicting current tax systems in both purely domestic and international settings.” (P. 7.)

Among the tasks the authors do not purport to undertake is to explore either the legal difficulties of implementing a DBCFT in particular jurisdictions or many of the collateral economic consequences of the transition to such a tax, particularly by the United States.

With regard to the first, it is unclear whether the House Republican implementation would apply to partnerships as well as corporations. Choice of entity has always been a significant part of U.S. tax planning because of small but consequential differences between corporate and individual taxation. Regardless of how the partnership issue is resolved, any implementation would have to deal with the massive arbitrage possibilities created by the much greater differences between income and cash flow taxation. What will prevent a taxpayer from borrowing through an entity subject to the income tax and spending through an entity subject to the DBCFT? How will we determine whether allocations have substantial economic effect if a partnership has both corporate and individual partners? The possibilities boggle the mind.

As to the second, one of the projected consequences of U.S. adoption of the tax would be a sharp rise in the dollar vis-à-vis other currencies. This, the authors assure us, would offset its other effects on trade neutrality and would therefore be a plus. But what about the estimated $3 trillion of dollar-denominated debt owed by non-bank debtors in emerging economies? See Lisa Abramowicz, The Emerging Markets’ Dollar Problem (2016). Both these debtors’ net worths and their cash flows, as measured in their home currencies, would be devastated by the projected change in exchange rates. Expect many such debtors to default. Hope that their defaults do not tip us back into another Great Recession. And this is only one non-obvious possible consequence.

It is impossible adequately to summarize a 98-page paper in a Jotwell review. The authors deal with many more issues, far more thoroughly, than I possibly could in the space available here. Read the paper.

What’s Up: BEPS and the New International Tax Order

Allison Christians, BEPS and the New International Tax Order, 6 BYU L. Rev. (forthcoming, 2017), available at SSRN.

It’s easy to underestimate the value of a good “what’s up” article. If you’ve been doing that, then you should take a look at “BEPS and the New International Tax Order” for a reminder of their value.

“What’s up” articles are the salve of the academy. They take a rapidly changing field of inquiry or policy space or legal doctrine and they encapsulate the state of play in a way that brings out and makes assessable the highlights.

This line of scholarly work is helpful to folks who have drifted from the area of inquiry and to those who are deeply lost in its weeds. Good what’s up scholarship should be evaluated on three criteria: (1) does the article provide an orienting matrix to the work in the particular area; (2) does it appropriately highlight the aspects of that rapidly changing area in ways that emphasizes what matters and de-emphasizes or ignores matters of little importance (put another way, does it respect the fact that not all developments are of equal importance); and (3) is it a pleasure to read.

“BEPS and the New International Tax Order” satisfies these criteria. Christians takes on the rapidly changing world of international tax as shaped by the Organisation for Economic Co-operation and Development (OECD). The OECD has served as the front player in shaping the policy space for governments responding to multinational company tax strategies that result in a reduction of tax bases and that shift profits from high to low-tax jurisdictions, hence the name of the OECD response – the “base erosion and profit shifting” (BEPS) project.

That project has been moving with support from the G20 over the last several years. The aim of Christians’s article is three-fold. She explains the role of the OECD as a “tax policy consensus-building network.” (P. 1609.) That claim builds on her earlier work, where she explores the role of the OECD as a policy-setter and the complexity of that role in the face of the OECD’s inability to regulate using formal (hard) law. In this part of the article, she reveals the complex interaction of legal instruments, model treaties and guidance, and peer review and monitoring as mechanisms for shifting the policy space in the international tax arena. Most interesting is her discussion of the peer review and monitoring process. The use of peer countries to assist as pressure-points for domestic legal and administrative change in the tax field is an under-explored area and Christians’s work should spur colleagues to develop research agendas that help us better understand the function of peer monitoring.

Christians’s second aim is to identify the OECD’s BEPS tax policy priorities. She identifies country-by-country reporting of how much tax is paid in each country in which the multinational operates, practices to reduce harmful tax competition, fixes for tax treaty abuse, and treaty-based dispute resolution as the four major priorities to which we should attend. For each of these priorities, Christians lays out the OECD’s minimum standards and speculates about the extent to which these standards are moving targets, likely to be adjusted in the near or medium-term.  There’s lots to be attentive to in this part of the paper: Is there any base-building advantage of the use of a nexus approach for allocating income from intellectual property? Will the exchange of tax rulings be helpful for tax administrations seeking to better enforce domestic law? How will peer monitoring effect the use of arbitration to resolve treaty disputes? How does the OECD plan to support capacity building for non-member states willing to sign on to its articulated priorities?

Finally, Christians’s third aim is to connect the priorities with implementation plans. The OECD has taken a multifaceted approach, with changes proposed to domestic legislation, new bilateral treaties, a new multilateral tax treaty, the adaptation and adoption of OECD models and guidance, and peer review.

By dividing the article in this way, Christians offers us hope for making sense of the voluminous materials produced out of the BEPS project. We can hang on to the four key priorities and make sense of how the OECD intends to advance those priorities, given its inability to enact binding rules.

Even more fun, and stepping out from the benefits of what’s up scholarship, Christians carries on in her signature way about the interaction between the rich OECD countries and the “others” – those countries who have been excluded from the OECD’s international tax agenda setting. Perhaps less characteristic of Christians’s work is a hint of optimism in the conclusion: “The Inclusive Framework thus introduces a potential avenue for non-OECD countries to have a meaningful say in norm building exercises undertaken by the OECD, but with a great deal of agenda-setting directed mainly by OECD member states, the outcome is not yet certain.” (P. 1645.)

Do Taxes Motivate Corporate Managers?

Lily Batchelder, Accounting for Behavioral Considerations in Business Tax Reform: The Case of Expensing (Feb. 5, 2017), available at SSRN.

Tax scholarship is interdisciplinary. To evaluate tax policy it helps to know at least a little about economics, a little about philosophy, something about budget processes, and a lot about the dizzying creativity of the marketplace in exploiting loopholes and facilitating tax-advantaged transactions. In her recent article Accounting for Behavioral Considerations in Business Tax Reform: The Case of Expensing, Lily Batchelder shows us that we must add financial accounting and firm (and corporate managers’) behavioral considerations to the mix.

The article evaluates which of three policies, adopted on a revenue neutral basis to replace our current regime of accelerated depreciation, would cause the largest increase in new investment by the corporate sector. The three policies are: expensing of new investments combined with higher statutory corporate rates; lower statutory rates combined with more gradual and economically accurate economic depreciation; and an investment tax credit combined with economic depreciation.

The conventional wisdom is that the first of these options, allowing for current expensing of new investment, will have the biggest bang-for-the-buck. But the analysis that yields this conclusion assumes that corporate managers choose investments to maximize the after-tax net present value of the investment returns. If that were true, managers would care about the marginal rate applicable to the investment, which is zero (at least as to the normal returns) if the investment is equity financed and the cost of the investment is expensed. The key insight that Batchelder shares is that managers don’t look at the marginal rate. The financial accounting literature shows that they make their decisions based on either the statutory rate or their “book” tax rate, because these are what affect income for financial reporting purposes. Neither rate reflects the value of tax deferral, so managers tend not to incorporate the benefits of tax deferral when making investment decisions. The best of the three policies is instead to eliminate accelerated depreciation and use the revenue to finance a statutory rate cut.

This paper makes two significant contributions. The first is to bring evidence on the tax variables that affect managers’ decisions to a live debate about how to increase investment. Batchelder not only canvasses relevant accounting theory and empirics, but also corroborates the incentives created by financial accounting standards by talking with corporate managers. The care with which she buttresses this important premise of her argument makes her conclusions about the ineffectiveness of expensing that much more credible. The second contribution is her argument that the optimal investment policy—at least in terms of maximizing the increase in new investment—is one that minimizes the capital-weighted relevant rate on new investment.

It doesn’t make sense to lower the marginal rate on new investment if the benefit is entirely inframarginal and generates no new investment. Different firms rely on different rates, and if we knew which rate each firm focused on, we might lower just that rate, for just that firm. Since that’s impracticable, Batchelder’s solution is to calculate the average target rate across all firms, weighted by the firms’ capital, and minimize that average. Note that this average rate isn’t the rate that is targeted by any one firm. To conclude that the optimal policy is the one that minimizes that average rate, Batchelder must assume that the elasticity of investment responses to changes in this rate are constant across firms, regardless of which rate they focus on. This assumption is worthy of further investigation. Presumably there is some reason that some firms focus on the statutory rate while others focus on the marginal rate. It could well be that the same managerial preferences, incentives, or constraints that cause some firms to focus on statutory rates also influence their investment behavior. If this were true, it could imply that a mix of policies, including investment tax credit, selectively available expensing, and lower statutory rates, might be the best approach.

Moreover, if deferral generally doesn’t matter to corporate managers, then we should also ask why we don’t provide for even slower depreciation or perhaps delay basis recovery at disposition in exchange for lower headline rates. Batchelder rightly notes that this would mean that firms will carry a lot of assets with built-in losses that could lead to asset churning, but this worry is in tension with the premise that there are very few firms that care about the timing of tax income and losses to begin with. If that’s the case, then we shouldn’t expect much churning after all.

Finally, a comprehensive analysis of these policy options would require some understanding of the tax sensitivities of non-corporate entities. Since the benefits of deferral accrue directly to investors in such entities, then we might expect that they would be more attuned to, and force managers to be more responsive to, the benefits of expensing. Batchelder’s data don’t allow her to calibrate her estimates by including these entities, but incorporating them would make for an important extension.

Understanding how policy interventions affect taxpayer behavior requires knowing the objectives of those taxpayers and the constraints that they face. Research in behavioral economics, particularly the literature on tax salience, has revealed some of the ways that individuals may not respond rationally to taxes. However, much less work has been done on the possibility that the assumption of economic profit maximization may fail in the case of firms. This paper is an important contribution in remedying this deficit in the scholarship.

In some sense, the marriage of accounting and tax law should be a natural one. Tax lawyers are accustomed to thinking about the pernicious consequences that flow when substance and form are allowed to come apart. They are sensitive to how taxpayers respond to labels such as “debt” and “equity,” or “employee” and “independent contractor” even when the underlying economic reality is the same. Accountants are engaged in a similar enterprise. It would seem that tax lawyers and accountants have a lot to talk about, and Lily Batchelder’s paper is a wonderful illustration of the important insights that can be generated from that conversation.
