If you are an IFA member or are attending IFA this fall, you can now download the full IFA 2017 Cahiers. The general report for Subject 1 on BEPS is co-authored by myself and Stephen Shay and is also available on SSRN. Here is the abstract:
The G20/OECD’s multi-year campaign to combat base erosion and profit shifting (BEPS) marks a critical step in the evolution of the international tax regime and the roles of institutions that guide it. This General Report for Subject 1, IFA Congress 2017, provides a snapshot of the outcomes of the BEPS project by comparing national responses to key mandates, recommendations and best practices through the end of October, 2016 based on National Reports representing the perspectives of 48 countries. These National Reports reveal that the impact of the BEPS initiative on a particular country corresponds to at least three key factors, namely: (1) the extent to which domestic law is already in substantial compliance with BEPS outcomes; (2) the degree to which implementation of BEPS outcomes appears capable of delivering positive revenue or economic results, or both, relative to a country’s experiences and perceptions prior to BEPS; and (3) the type and degree of involvement of a country in the formative stages of the initiative preceding the release of the final BEPS action plans. As BEPS continues to unfold, it is difficult to gauge the full extent to which countries in fact will adhere or defect from the rules. However, the BEPS project has witnessed the transition of global tax governance from the OECD countries exclusively to global fora. This leaves open questions regarding agenda-setting for international tax policy going forward. As we conclude this interim snapshot of the origins, standards, and responses to BEPS to date, we look to future IFA congresses for answers to these questions and a final assessment of the BEPS project.

This Article examines international law limitations on the ascription of citizenship in the context of U.S. taxation of non-resident citizens. U.S. citizenship practice is exceptionally generous, extending citizenship to almost all persons in its territory at the moment of birth. At the same time that it is generous at the front end, U.S. citizenship is sticky at the back. Termination of citizenship on the individual’s part involves substantial fees and tax compliance. It is difficult to shed a citizenship one may never have wanted in the first place.
This stickiness would be inconsequential if few costs were associated with the status. But the United States taxes its citizens on a worldwide basis. The 2010 enactment of the Foreign Account Tax Compliance Act has ramped up historically lax enforcement and imposes substantial administrative burdens on even middle-earner citizens abroad.
In this frame, U.S. birthright citizenship and expatriation regimes may violate international norms, especially with respect to those "accidental Americans" who departed the United States as children. Even in the context of extremely relaxed historical constraints on state nationality practice, there were acknowledged nineteenth century limitations on the extension of citizenship to individuals with insufficient connection to a state -- citizenship over-claiming, as it were. The article also describes the historical requirement that naturalization be volitional, a norm now appropriately applied in some cases in the context of birthright citizenship.
To the extent the ascription of U.S. citizenship compromises individual rights, there are tax fixes and there are citizenship fixes. Citizenship fixes include opt-in and opt-out mechanisms for birthright citizenship. The better solution may lie in frictionless exit for those with nominal ties to the national community. Though reform is more likely to be accomplished through the tax regime, the moment highlights the over-inclusiveness of U.S. citizenship and the growing salience of international law to citizenship practices.I'm less confident than Peter that reform will ever be delivered through the tax regime, but I am very glad to see this important contribution to the growing literature focusing on the citizenship/taxation link.
Taxpayers who hide assets abroad to evade taxes present a serious enforcement challenge for the United States. In response, the U.S. has developed a family of initiatives that punish and rehabilitate non-compliant taxpayers, raise revenues, and require widespread reporting of offshore financial information. Yet, while these initiatives help catch willful tax cheats, they have also adversely affected immigrants, Americans living abroad, and “accidental Americans.”
This Article critiques the United States’ offshore tax enforcement initiatives, arguing that the U.S. has prioritized two problematic policy commitments in designing enforcement at the expense of competing considerations: First, the U.S. has attempted to equalize enforcement against taxpayers with solely domestic holdings and those with harder-to-detect offshore holdings by imposing harsher reporting requirements and penalties on the latter. But in doing so, it has failed to appropriately distinguish among differently situated taxpayers with offshore holdings. Second, the U.S. has focused on revenue and enforcement, ignoring the significant compliance costs and social harms that its initiatives create.
The confluence of these two policy commitments risks creating high costs for the wrong taxpayers. While offshore tax enforcement may have been designed to catch high¬-net-worth tax cheats, it may instead impose disproportionate burdens on those immigrants and expatriates who have less ability to complain, comply, or “substitute out” of the law’s grasp. This Article argues that the U.S. should redesign its enforcement approach to minimize these risks and suggests reforms to this end.The paper provides a thorough review of the panoply of offshore enforcement programs and mechanisms and documents the harms of their dragnet approach, especially on the most vulnerable and least likely targets. A significant contribution to the literature.
Over at Surly Subgroup, Leandra Lederman has posted Death, Taxes, and a Beach Read, a review of a series of novels by Diane Kelly, a former CPA and tax attorney turned romance novelist who "had the pleasure of working with a partner later convicted of tax shelter fraud [and] served a stint as an Assistant Attorney General for the State of Texas under an AG who pled guilty to criminal charges related to the tobacco company lawsuits." Leandra told me about these books last week when I was in Bloomington, and I have never heard of them before, so it is fun to see her write them up. From her post:
It never occurred to me to blog about [the series] until I read the first page of “Death, Taxes, and Cheap Sunglasses” while on a plane, and saw a link with tax issues I frequently write about. The opening paragraph reads:
“I slid my gun into my purse, grabbed my briefcase, and headed out to my car. Yep, tax season was in full swing once again, honest people scrambling to round up their receipts, hoping for a refund or at least to break even. As a taxpayer myself, I felt for them. But as far as tax cheats were concerned, I had no sympathy. The most recent annual report indicated that American individuals and corporations had underpaid their taxes by $450 billion. Not exactly chump change. That’s where I came in.”
I had just presented my latest tax compliance article, “Does Enforcement Crowd Out Voluntary Tax Compliance?” and here were tax gap figures showing up in a novel! ...Leandra notes that of course the novel simplifies, referring to “underpaid”taxes: official tax gap measurements by the IRS (see e.g. 2006; 2012) include late payment and filing/reporting failures. Leandra continues:
The heroine of this "romantic mystery series" is CPA Tara Holloway, who's described as "kicking ass, taking social security numbers, and keeping the world safe for honest taxpayers." She's a Special Agent with the IRS's Criminal Investigation Division....
Diane Kelly takes a few liberties with what Tara can get away with. The acknowledgments in “Death, Taxes, and Peach Sangria” include the following statement: “To the IRS special agents, thank you for sharing your fascinating world with me and for all you do on behalf of honest taxpayers. Please forgive Tara for being such a naughty agent and breaking the rules.”Leandra recommends readers start with the first novel in the series, Death, Taxes, and a French Manicure. But if Tara's mission is to close the tax gap, is it ok to buy the book on Amazon?

Arthur Cockfield has posted a paper of interest, entitled How Countries Should Share Tax Information. Here is the abstract:
There are increasing policy concerns that aggressive international tax avoidance and offshore tax evasion significantly reduce government revenues. In particular, for some low income countries the amount of capital flight (where elites move and hide monies offshore in tax havens) exceeds foreign aid. Governments struggle to enforce their tax laws to constrain these actions, but are inhibited by a lack of information concerning international capital flows. The main international policy response to these developments has been to promote global financial transparency through heightened cross-border exchanges of tax information. The paper discusses elements of optimal cross-border tax information exchange laws and policies by focusing on three key challenges: information quality, taxpayer privacy, and enforcement. Relatedly, the paper discusses how the exchange of automatic ‘big tax data’ combined with data analytics can help address the challenges.Cockfield seeks to find a solution that balances the need of the state for extensive information in order to protect the integrity of the income tax system against the need of the individual for protection from abuse by the state. That is no easy balance to strike. From the paper:
All of [the recent information gathering and exchange] efforts seek to provide governments with more and better tax information, and reduce costs through agreement on underlying EOI rules and principles. The reforms, however, largely do not address how financial secrecy laws subvert global financial transparency initiatives. Nor do they address legal technical complexity that raises transaction costs, and makes it even harder for low and middle income countries to implement and enforce EOI. While the EOI reforms are positive steps, given an environment of high transaction costs it may be difficult to make progress in addressing key policy challenges....
Data availability, usefulness and verifiability are three components of high quality information that can help governments pursue their cross-border investigations and audits. In particular, transferred information should be relatable to domestic tax identification measures, and checked against third party reporting, and withholding tax disclosures. Once this is done, governments can conduct analysis to determine audit risk by focusing on issues such as taxpayer segmentation, dealings between the taxpayer and offshore service providers, and cross-indexing tax and financial information against non-tax data (e.g., insurance policy disclosures).
Against this desire for high quality tax information stands (shrugs?) taxpayer privacy concerns. The apprehensions arise from the varied levels of domestic legal protection afforded to privacy rights, along with the risk of abuse or misuse of transferred information. Accordingly, broader multilateral agreement on privacy protections is likely a prerequisite to effective EOI. This hoped-for cooperation is hindered by the fact that many countries refuse to abolish their financial secrecy laws, which stands as one of the main barriers to optimal reform.My view is that maintaining the integrity of the income tax system appears to require building the panopticon, and much more besides. The steady decline of support for coherent corporate income taxation makes greater and greater individual surveillance necessary, while also making personal income taxation harder. I am not sure where the point lies at which the costs and risks attendant to building the necessary compliance and enforcement infrastructure exceed the benefits of maintaining personal taxes based on income.

As observers of global tax policy know, international tax issues are dealt with in bilateral treaties that more or less adhere to a 'model' tax treaty developed and periodically updated by the OECD (provisions in a rival UN Model are occasionally invoked, and the US has its own model with its own distinctions and idiosyncrasies). There are those who have long lamented the problem of having thousands of bilateral agreements that can't be easily or quickly updated when the OECD revises the model (thus curbing the impact of OECD soft law).
As part of the base erosion and profit shifting (BEPS) initiative, the OECD is currently developing a
"Multilateral instrument on tax treaty measures to tackle BEPS" which would be used to 'modify' all existing tax treaties in force among signatory countries. The OECD says this mechanism (which it calls an 'innovative approach') 'would preserve the bilateral nature of tax treaties' even as it modified all existing bilateral treaties 'in a synchronized way'. The OECD says there are "limited precedents" for modifying bilateral treaties with a multilateral instrument.
But are there really any precedents at all? I couldn't think of any off-hand. A quick check with a few international law colleagues yielded few comparators. Tim Meyer suggested the EU harmonizing efforts on Bilateral Investment Treaties (BITs) as a candidate, albeit noting that this does not contemplate directly overriding existing BITs but requires EU members to change their bilateral arrangements to conform with EU investment policy.
Tim also made the interesting observation that"treaties that reference customary international law standards, such as BITs’ reference to the minimum standard of treatment" could be overridden in a somewhat similar fashion. He explained that "[i]f custom changed, such as through the promulgation of soft law documents or multilateral treaties, it would change the BITs that incorporate the customary standard. That isn’t exactly the same thing [as the new OECD multilateral instrument], but similar."
The OECD's work in developing "global consensus" has in the past led some to describe OECD standards as "soft law" and others to suggest that the OECD may be understood to articulate customary international tax law; moreover the OECD has itself now taken to describing its model as soft law (including in its 2014 report on the multilateral instrument). I have urged caution in defining OECD proclamations as soft law or customary law given the OECD's exclusive membership of mainly rich countries, which excludes all of the BRICs and most of the rest of the world, as I think the nomenclature lends an imprimatur of legitimacy to OECD proclamations that may not be deserved. But it seems clear that the BEPS action items, and the new global forum to "monitor compliance" with them, are intended to overcome the exclusivity problem while endowing OECD norms with ever-greater law-like effect (without offending the unicorn that is "tax sovereignty").
It seems likely to me that a multilateral agreement that modifies existing tax treaties is actually intended to ultimately replace those treaties, making small and incremental modifications until the underlying bilateral treaties become superfluous or extinct. Accordingly I view the OECD's multilateral 'modification' function to be an exercise in creeping harmonization as well as "ossification" (or maybe transformation) of soft law into hard law.
Adding together the other elements of BEPS, including the new global forum to compel national compliance with 'minimum standards' as they develop, I recently suggested that the OECD's tax folks are giving birth to a new global tax order complete with rules, audits, and reform processes. This is perhaps not the order envisioned by those who have in the past called for global tax coordination in a supranational body for the sake of pursuing global tax justice. If the OECD-based regime is not fully supranational yet, it is close, and it looks increasingly inevitable once it sets a multilateral agreement in place.
There are many fascinating threads of soft law and public international law are at work in these developments. I recently came across an article by Jung-Hong Kim on the topic, entitled A New Age of Multilateralism in International Taxation?, abstract:
With the OECD/G20 BEPS project, the current international tax landscape is facing challenges and changes unprecedented for the past several decades. This paper looks at the development of bilateralism and multilateralism in the current international tax regime, takes stock of the BEPS works and analyzes the proposed Multilateral Instrument. Then, the paper discusses the emerging multilateral tax order in international taxation.
Historically, bilateralism has been the constant trend of tax treaties, and later multilateral tax treaties have emerged in some regional areas. There being some deficiencies with bilateral treaties such as dilapidation, delay in entry into force and vulnerability to treaty shopping, the experience of multilateral tax treaties can help build a foundation for future development of a multilateral tax treaty to complement the bilateral tax treaty network.
With a caveat that BEPS output is fluid at this stage, drawing on the various examples of existing non-tax multilateral treaties, the Multilateral Instrument will be a desirable and feasible tool to reflect the necessary changes resulting from BEPS project. For Korea whose tax treaties need a systematic upgrade after a noticeable growth in quantity, the negotiation on the Multilateral Instrument of the BEPS project will be a great opportunity to revisit the existing bilateral tax treaties and to make appropriate amendments with bilateral treaty partners in multilateral format.
Beyond BEPS, supposing that the work on the Multilateral Instrument results in a multilateral convention, the inevitable question is the emergence of a multilateral tax order. In terms of feasibility of such a multilateral tax order, there are both positive and negative sides. The positive side is that the relative success of Global Forum on Tax Transparency can be a guidance on the post-BEPS multilateral tax order. On the other hand, the phenomenon of diminishing multilateral trade regime and bilateral investment treaty regime seem to be a negative evidence. Another point to consider is the appropriate forum to manage the multilateral tax order. For this, there are two competing organizations, i.e., the OECD CFA and UN tax committee, each of which having some limit to be developed into an intergovernmental forum.
After all, the essential question will be how those major players such as the U.S., EU, China, India etc. could build a consensus by compromising on the institutional and substantive aspects of the multilateral tax order. For now, for the emerging multilateral tax order to proceed on a sound basis, the work of the BEPS project should bear substantive and meaningful fruits.
The IRS faces constant funding pressure from Congress, despite becoming a victim of constant mission creep thanks to Congressional mandates (ACA and FATCA in particular). Over the years many have pled with Congress to stop underfunding the agency. The latest comes from seven former commissioners, who note that not least among the reasons to fund the IRS is the need to spend money on cyber security as the IRS fends off one million hacking attempts each week.
That's a lot of hacking because of course the payload is enormous. FATCA has surely expanded the payload significantly by developing an enormous database of personal information attached to bank account numbers and detailed account activity on a global scale. Even a small breach of security with respect to that vault will be disastrous for the taxpayers involved.
The commissioners also suggest that the IRS workload is going to increase due to BEPS. BEPS is expected to result in more treaty-based conflicts among jurisdictions, so I expect more competent authority hours will be needed. But it's likely also the case that country-by-country reporting requirements will add another enormous treasure trove of information to the database, further increasing the payload.
At minimum, Congress has simply got to fund security for this massively expanding taxpayer information database.

Subject: IRS Appropriations for Fiscal Year 2016
Dear Chairman Cochran, Vice Chairwoman Mikulski, Chairman Rogers and Ranking Member Lowey:
We are all former Commissioners of the Internal Revenue Service. Over the last fifty years we served during the administrations of Presidents John F. Kennedy, Lyndon B. Johnson, Ronald Reagan, George H.W. Bush, William J. Clinton, and George W. Bush.We are writing to express our great concern about the proposed reductions by the House and Senate in appropriations for the Internal Revenue Service for the current fiscal year that will end on September 30, 2016. We understand that the Appropriations Committees in the House and Senate have proposed to reduce the FY 2015 IRS appropriation of $10.9 billion by $838 million and $470 million, respectively, for the current fiscal year. If Congress were to reduce the IRS appropriation for the current year, it would represent yet another reduction in the IRS appropriation. The appropriations reductions for the IRS over the last five years total $1.2 billion, more than a 17% cut from the IRS appropriation for 2010. None of us ever experienced, nor are we aware of, any IRS appropriations reductions of this magnitude over such a prolonged period of time. The impact on the IRS of these reductions is that the IRS has lost approximately 15,000 full-time employees through attrition over the last five years, with more losses likely in the current fiscal year unless Congress reverses the funding trend. These staffing reductions come at a time when the IRS workforce is aging, with nearly 52% of IRS employees now over the age of 50 and 24% already eligible to retire. Three years from now, 38% of IRS employees will be eligible to retire. This loss of IRS knowledge and experience is alarming, particularly in light of the fact that, out of a present workforce of about 85,000 employees, the IRS has only about 3,400 employees under the age of 30 and only 384 employees under the age of 25 due to hiring freezes for budgetary reasons at the IRS since 2010 and periodically from 2005 to 2010. Over the last fifty years, none of us has ever witnessed anything like what has happened to the IRS appropriations over the last five years and the impact these appropriations reductions are having on our tax system.These reductions in IRS appropriations are difficult to understand in light of the fact that, at the same time these reductions have occurred, the Congress repeatedly has passed major tax legislation to substantially increase the IRS workload. Most recently the Congress passed the Foreign Account Tax Compliance Act and the Patient Protection and Affordable Care Act, two major new programs, each of which significantly expands the IRS' tax administration burdens. The IRS personnel reductions come at a time when the IRS is stretched to the breaking point to cope with tax enforcement challenges attributable to global and domestic changes that are impacting our tax system. Increasingly, the United States is facing tax challenges as the result of efforts that are taking place in the international tax arena to deal with the tax non-compliance that is accompanying the continued globalization of business and investment activities. The most recent tax changes to address international tax non-compliance are proposed in the Organization for Economic Cooperation and Development's (OECD) Base Erosion and Profit Shifting Report. Regardless of one's view of these proposed changes, it is clear that the IRS will be substantially impacted by changes and challenges of other countries who adopt them.Additionally, increasing incidents of identity theft and refund fraud are being perpetrated against our tax system by large, sophisticated organized crime syndicates around the world. These criminals seek to file false returns and claim fraudulent refunds using personal taxpayer data obtained from sources outside the IRS. At the same time, many unlicensed, unregulated return preparers are preparing and filing fraudulent tax refund returns. Every time there is an information technology hacking event in the public or private sectors in which Social Security numbers are stolen, the likelihood exists for additional identity theft and refund fraud. The growing refund fraud challenge to our tax system is especially alarming to us because of the need, which is fundamental to our tax system, for the IRS to be able to assure taxpayers who are paying their fair share of taxes that other taxpayers are doing the same thing. To emphasize the seriousness of refund fraud, the Government Accountability Office earlier this year placed identity theft and refund fraud on its list of "high risk areas" in the federal government, a sure sign to each of us that the IRS should have more, not fewer, enforcement resources to deal with this threat to the integrity of our tax system,To place the impact on our tax system of the Congressional IRS appropriations reductions over the last five years in its proper context, Congress almost annually over the last 25 years has passed legislation that has imposed additional burdens on IRS tax collection and administration under our revenue laws. During this time, the Congress also repeatedly added more and more socio-economic incentives to the tax code and called upon the IRS to administer these new socio-economic programs, including healthcare, retirement, social welfare, education, energy, housing, and economic stimulus programs, none of which is related to the principal job of the IRS to collect revenue. At the same time, Congress passed even more legislation to pay for these tax spending programs. The result is that almost 30 years after the 1986 Tax Reform Act, our tax laws are a mess. Our tax laws have become so difficult for taxpayers to understand that 80% of all individual taxpayers now use paid consultants or software to prepare their income tax returns. Because of insufficient IRS resources in FY 2015, an average of more than 60 percent of the taxpayers who called the IRS for assistance in preparing their returns during the last filing season were unable to reach an IRS assistor, even after many taxpayers had remained on the telephone for more than 30 minutes before they were automatically cut off because of the volume of calls, which the reduced numbers of IRS assistors were unable to handle. Equally serious are the cybersecurity threats illustrated by the problem that occurred earlier this year involving unauthorized attempts to access taxpayer information using the IRS' Get Transcript online application. Separately, the IRS continues to experience about one million attempts each week to hack into its main information technology systems. Although the IRS has so far successfully thwarted these attacks and its main systems remain secure, all of this astonishes us and emphasizes to each of us that the IRS taxpayer assistance and IRS information technology resources are severely underfunded, especially when compared to the increasing cybersecurity budgets of private sector companies.It is clear to each of us that the IRS appropriations reductions over the last five years materially and adversely affect the ability of the IRS to assist taxpayers who are trying to comply with their tax obligations, as well as the ability of the IRS to detect and deter taxpayers who have not complied with their tax obligations. Recently, we understand that the IRS estimated a direct annual revenue loss to the Federal government in tax enforcement at $6 billion last year and $8 billion this year, due to such appropriations reductions. Historically, for every dollar invested in IRS tax enforcement, the United States received $4 or more in return, and we understand that continues to be true today.The Congressional Budget Office in its June 2015 Long-Term Budget Outlook projected future fiscal challenges to the United States because of the large and increasing size of our national debt and rising future operating deficits attributable to an aging U.S. population and rising healthcare costs. It, therefore, is imperative that our tax system in the future operate at an optimal level in order to maximize the revenues the IRS collects. For that to happen, the IRS must be able to assist taxpayers who are trying to comply with their tax obligations, and at the same time be able to enforce the tax laws against those taxpayers who have not complied with their tax obligations. In short, because of our country's fiscal and other challenges, our tax system must work and work well to collect the taxes that are owed.Some have argued that the IRS can solve these problems by simply becoming more efficient. This argument ignores the reality that the IRS is already, by far, the most efficient tax collection agency among large countries in the world. The OECD recently released its bi-annual analysis of tax administration across the developed world and reported, based on 2013 statistics which don't reflect the most recent IRS budget cuts, that the amount the IRS spends to collect a dollar in taxes is approximately half the average amount spent by all OECD countries. Germany, France, England, Canada and Australia all spend as much as two to three times the amount the IRS does to collect a dollar of revenue.In light of the foregoing, we fail to understand how it makes any logical sense to continue to reduce, rather than increase, the IRS budget for FY 2016 in order to optimize the IRS' ability to provide taxpayer service and to enforce the tax laws to increase revenue collections. To put it succinctly, we do not understand why anyone with present and projected debts and annual losses as large as those of the United States would refuse to pay for telephone assistance to people trying to fulfill their tax obligations, would turn their back on $8 billion annually in additional revenue, or would fail to make an investment that offers a return equal to at least four times the amount invested. For these reasons, we respectfully call upon each of you to support and work to accomplish the passage of an IRS appropriations request for FY 2016 that is substantially in excess of the appropriation for the IRS in FY 2015.Mortimer M.
