The U.S. Congress charged the National Academies with conducting a review of the Internal Revenue Code to identify the types of and specific tax provisions that have the largest effects on carbon and other greenhouse gas emissions and to estimate the magnitude of those effects. To address such a broad charge, the National Academies appointed a committee composed of experts in tax policy, energy and environmental modeling, economics, environmental law, climate science, and related areas. For scientific background to produce Effects of U.S. Tax Policy on Greenhouse Gas Emissions, the committee relied on the earlier findings and studies by the National Academies, the U.S. government, and other research organizations. The committee has relied on earlier reports and studies to set the boundaries of the economic, environmental, and regulatory assumptions for the present study. The major economic and environmental assumptions are those developed by the U.S. Energy Information Administration (EIA) in its annual reports and modeling. Additionally, the committee has relied upon publicly available data provided by the U.S. Environmental Protection Agency, which inventories greenhouse gas (GHG) emissions from different sources in the United States. The tax system affects emissions primarily through changes in the prices of inputs and outputs or goods and services. Most of the tax provisions considered in this report relate directly to the production or consumption of different energy sources. However, there is a substantial set of tax expenditures called "broad-based" that favor certain categories of consumption-among them, employer-provided health care, owner-occupied housing, and purchase of new plants and equipment. Effects of U.S. Tax Policy on Greenhouse Gas Emissions examines both tax expenditures and excise taxes that could have a significant impact on GHG emissions.

This Selected Issues paper for the United States discusses the microeconomics of the country—household wealth and savings. Households’ consumption-saving decisions have an important bearing on the U.S. economic outlook. This paper demonstrates how households with consistently lower income, which have shown growth in the years prior to the crisis, experienced larger declines in their saving rates and a larger rise in their indebtedness before the crisis, contributing significantly to the dynamics of the mean saving rate.

This paper describes, and where possible tentatively quantifies, likely tax spillovers from the U.S. corporate income tax reform that was part of the broader 2017 tax reform. It calculates effective tax rates under various assumptions, showing among other findings, how the interest limitation and the Foreign Derived Intangible Income provision can raise or reduce rates. It tentatively estimates that under constant policies elsewhere, the rate cut will reduce tax revenue from multinationals in other countries by on average 1.6 to 5.2 percent. If other countries react in line with historical reaction functions, the revenue loss from multinationals rises to an average of 4.5 to 13.5 percent. The paper also discusses profit-shifting, real location, and policy reactions from the more complex features of the reform.

In the increasingly global economy, domestic tax policies have taken on a new importance for international economics. This unique volume compares the tax reform experiences of Canada and the United States, two countries with the world's largest bilateral flow of trade and investment. With the signing of the U.S.-Canada Free Trade Agreement and the tax reforms of the 1980s, there has been some harmonization of tax systems. But geographic, cultural, and political characteristics shape distinct national social policies that may impede harmonization. As the U.S. and Canadian economies become even more integrated, differences in tax systems will have important effects, in particular on the relative rates of economic growth. In this timely study, scholars from both countries show that, while the United States and Canada exhibit similar corporate tax structures and income tax systems, they have very different approaches to sales tax and social security taxes. Despite these differences, the two countries generate roughly the same amounts of revenue, produce similar costs of capital, and produce comparable distributions of income.

This paper examines the main distortions of the U.S. corporate income tax (CIT), focusing on its international aspects, and proposes a set of reforms to alleviate them. A bold reform to replace the CIT with a corporate-level rent tax could induce efficiency-enhancing reform of the international tax system. Since fundamental reform is politically difficult, this paper also proposes an incremental reform that would reduce tax expenditures, reduce the CIT rate to 25-28 percent, and impose a minimum rent tax on foreign earnings. Finally, this paper analyzes empirically the likely impact of the incremental on corporate revenues outside the U.S.: Though a U.S. rate cut would likely lower revenues elsewhere, implementation of a strong minimum tax could more than offset that effect for most countries with effective tax rates above 15 percent.

This paper articulates and, using newly-assembled data, explores how international taxation affects aggregate tangible cross-border investment. Spillovers from statutory tax rates abroad seem: As sizable as effects from the host’s rate; larger than previous consensus values (attributed to a systematic bias from FDI data); and consistent with ‘implicit’ profit shifting through real investment (rather than ‘paper’ profit shifting). Contrary to much policy discussion, the results also imply that: Host countries’ marginal effective tax rates have at best a weak effect on real investment; those elsewhere have none; and, applied to the prospective global minimum tax, inward tangible investment in most sample countries will increase.

This paper explores the nature, significance and policy implications of spillovers in international corporate taxation—the effects of one country’s rules and practices on others. It complements current initiatives focused on tax avoidance by multinationals, notably the G20-OECD project on Base Erosion and Profit shifting (BEPS). The paper draws on the IMF’s experience on international tax issues with its wide membership, including through technical assistance (TA), and on its previous analytical work, to analyze spillovers and how they might be addressed. In doing so, it goes beyond current initiatives to look at a wide set of possible responses.

This book explores one of the most dynamic and exciting aspects of globalization—international tax competition. With rising mobility and soaring capital flows, individuals and businesses are gaining freedom to work and invest in nations with lower tax rates. That freedom is pressuring governments to cut taxes on income, investment, and wealth. In Global Tax Revolution, Chris Edwards and Daniel Mitchell chronicle tax reforms around the world in recent decades. They describe the dramatic business tax cuts of Ireland, the flight of successful people from high-tax France, and the introduction of simple “flat taxes” in more than two dozen nations. Like other aspects of globalization, tax competition is generating intense political opposition. Numerous governments and international organizations are fighting to restrict tax cuts. Edwards and Mitchell challenge those efforts, arguing that tax competition is helping to advance prosperity, expand human rights, and rein in bloated governments.The authors argue that the U.S. economy can be revitalized by embracing competition and overhauling the federal tax code. They discuss how current tax rules suppress wages and investment and describe the tax changes needed for workers and businesses to succeed in the fast-paced global economy. Rather than idly complaining about jobs and capital moving offshore, this book argues that policymakers need to embrace major tax reforms to ensure rising standards of living for Americans in the years ahead.
