"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.

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.

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.
