Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience interested in economic policy issues. This Web-only series replaced Staff Position Notes in January 2011.
Tax distortions are likely to have encouraged excessive leveraging and other financial market problems evident in the crisis. These effects have been little explored, but are potentially macro-relevant. Taxation can result, for example, in a net subsidy to borrowing of hundreds of basis points, raising debt-equity ratios and vulnerabilities from capital inflows. This paper reviews key channels by which tax distortions can significantly affect financial markets, drawing implications for tax design once the crisis has passed.
Most tax systems create a tax bias toward debt finance. Such debt bias increases leverage and may negatively affect financial stability. This paper models and estimates debt bias in the financial sector, and present novel estimates for investment banks and non-bank financial intermediaries such as finance and insurance companies. We find debt bias to be pervasive, explaining as much as 10 percent of total leverage for regular banks and 20 percent for investment banks, with the effects most pronounced before the global financial crisis. Going forward, debt bias is likely to once again gain prominence as a key driver of leverage decisions, underscoring the importance of policy reform at this juncture.
This paper investigates the role of tax incentives towards debt finance in the buildup of leverage in the nonfinancial corporate (NFC) sector, using a large firm-level dataset. We find that so-called debt bias is a significant driver of leverage, for both small and medium-sized enterprises and larger firms, with its effect accounting for about a quarter of leverage. The strength of this effect differs with firm size, the availability of collateral, income and income volatility, cash flow, and capital intensity. We conclude that leveling the playing field between debt and equity finance through tax policy reform would decrease NFC leverage, reducing economic risks posited by leverage.
Risks to macroeconomic stability posed by excessive private leverage are significantly amplified by tax distortions. ‘Debt bias’ (tax provisions favoring finance by debt rather than equity) has increased leverage in both the household and corporate sectors, and is now widely recognized as a significant macroeconomic concern. This paper presents new evidence of the extent of debt bias, including estimates for banks and non-bank financial institutions both before and after the global financial crisis. It presents policy options to alleviate debt bias, and assesses their effectiveness. The paper finds that thin capitalization rules restricting interest deductibility have only partially been able to address debt bias, but that an allowance for corporate equity has generally proved effective. The paper concludes that debt bias should feature prominently in countries’ tax reform plans in the coming years.
This paper examines the role of minimum taxes and attempts to quantify their impact on economic activity. Minimum taxes can be effective at shoring up the corporate tax base and enhancing the perceived equity of the tax system, potentially motivating broader taxpayer compliance. Where political and administrative constraints prevent reforms to the standard corporate income tax, a minimum tax can help mitigate base erosion from excessive tax incentives and avoidance. Using a new panel dataset that catalogues changes in minimum tax regimes over time around the world, firm-level analysis suggests that the introduction or reform of a minimum tax is associated with an increase in the average effective tax rate of just over 1.5 percentage points with respect to turnover and of around 10 percent with respect to operating income. Minimum taxes based on modified corporate income lead to the largest increases in effective tax rates, followed by those based on assets and turnover.
The research reported in this volume represents the second stage of a wide-ranging National Bureau of Economic Research effort to investigate "The Changing Role of Debt and Equity in Financing U.S. Capital Formation." The first group of studies sponsored under this project, which have been published individually and summarized in a 1982 volume bearing the same title (Friedman 1982), addressed several key issues relevant to corporate sector behavior along with such other aspects of the evolving financial underpinnings of U.S. capital formation as household saving incentives, international capital flows, and government debt management. In the project's second series of studies, presented at the National Bureau of Economic Research conference in January 1983 and published here for the first time along with commentaries from that conference, the central focus is the financial side of capital formation undertaken by the U.S. corporate business sector. At the same time, because corporations' securities must be held, a parallel focus is on the behavior of the markets that price these claims.
"The global economic and financial crisis has created important needs for fiscal consolidation. This document analyses potential instruments to raise additional tax revenues from the financial sector. The first section reviews the current policy objectives related to the taxation of the financial sector. The second section sheds some light on the current tax treatment of the financial sector. The third section discusses potential tax instruments to reach the goals. The fourth and fifth section respectively assess the advantages and drawbacks of a Financial Transaction Tax and a Financial Activities Tax."--Editor.
The tax rules of the United States and other countries have intended and unintended effects on the operations of multinational corporations, influencing everything from the formation and allocation of capital to competitive strategies. The growing importance of international business has led economists to reconsider whether current systems of taxing international income are viable in a world of significant capital market integration and global commercial competition. In an attempt to quantify the effect of tax policy on international investment choices, this volume presents in-depth analyses of the interaction of international tax rules and the investment decisions of multinational enterprises. Ten papers assess the role played by multinational firms and their investment in the U.S. economy and the design of international tax rules for multinational investment; analyze channels through which international tax rules affect the costs of international business activities; and examine ways in which international tax rules affect financing decisions of multinational firms. As a group, the papers demonstrate that international tax rules have significant effects on firms' investment and other financing decisions.
