A review of tax research

In this paper, we present a review of tax research. We survey four main areas of the literature: (1) the informational role of income tax expense reported for financial accounting, (2) corporate tax avoidance, (3) corporate decision-making including investment, capital structure, and organizational form, and (4) taxes and asset pricing. We summarize the research areas and questions examined to date and what we have learned or not learned from the work completed thus far. In addition, we provide our opinion as to the interesting and important issues for future research.

The Effects of Executives on Corporate Tax Avoidance

This paper investigates whether individual top executives have incremental effects on their firms’ tax avoidance that cannot be explained by characteristics of the firm. To identify executive effects on firms’ effective tax rates, we construct a dataset that tracks the movement of 908 executives across firms over time. The results indicate that individual executives play a significant role in determining the level of tax avoidance that firms undertake. The economic magnitude of the executive effects on tax avoidance is large. Moving between the top and bottom quartiles of executives results in approximately an eleven percent swing in GAAP effective tax rates; thus, executive effects appear to be an important determinant in firms’ tax avoidance.

How Much Will Firms Pay for Earnings that Do Not Exist? Evidence of Taxes Paid on Allegedly Fraudulent Earnings

This paper examines the extent, if any, to which firms pay additional income taxes on allegedly fraudulent earnings. Our sample consists of firms that restated their financial statements in conjunction with SEC allegations of accounting fraud during the years 1996 to 2002. By examining firms that were accused of fraud by the SEC we obtain a relatively clean sample of earnings overstatements and avoid having to rely on models of earnings management. By further focusing on restatements, we are able to estimate how much income tax was paid on the overstated earnings. The estimates in this paper represent the most direct evidence to date that firms are willing to sacrifice substantial cash to inflate their accounting earnings. Our detailed analysis of a sample of firms admitting to large earnings overstatements indicates that the mean firm sacrificed eleven cents in additional income taxes per dollar of inflated pre-tax earnings. In aggregate, the firms in our sample paid

Changes in Corporate Effective Tax Rates Over the Past Twenty-Five Years

Despite decades of research on how, why, and when companies manage earnings, there is a paucity of evidence about the geographic location of earnings management within multinational firms. In this study, we examine where companies manage earnings using a sample of 2,067 U.S. multinational firms from 1994 to 2009. We predict and find that firms with extensive foreign operations in weak rule of law countries have more foreign earnings management than companies with subsidiaries in locations where the rule of law is strong. We also find some evidence that profitable firms with extensive tax haven subsidiaries manage earnings more than other firms and that the earnings management is concentrated in foreign income. Apart from these results, we find that most earnings management takes place in domestic income, not foreign income.

Where Do Firms Manage Earnings

This paper investigates whether investor-level taxes affect corporate payout policy decisions. We predict and find a surge of special dividends in the final months of 2010 and 2012, immediately before individual-level dividend tax rates were expected to increase. We also find evidence that immediately before the expected tax increases, firms altered the timing of their regular dividend payments by shifting what would normally be January regular dividend payments into the preceding December. To our knowledge this is the first evidence in the literature about changes in the timing of regular dividend payments in response to tax law changes. For both actions (specials and shifting), we find that it was more likely for a firm to respond to individual-level tax rates if insiders owned a relatively large amount of the firm. Overall, our paper provides evidence that managers consider individual-level taxes in making corporate payout decisions.

The Taxman Cometh: Does Tax Uncertainty Affect Corporate Cash Holdings?

We investigate systematic changes in corporate effective tax rates over the past 25 years and find that effective tax rates have decreased significantly. Contrary to conventional wisdom, we find that the decline in effective tax rates is not concentrated in multinational firms; effective tax rates have declined at approximately the same rate for both multinational and domestic firms. Moreover, we find that within multinational firms, both foreign and domestic effective rates have decreased. Finally, we find that changes in firm characteristics and declining foreign statutory tax rates explain little of the overall decrease in effective rates. The findings have broad implications for research, as well as for current policy debates about reforming the corporate income tax.

Are Dividends Informative About Future Earnings

Despite decades of research on how, why, and when companies manage earnings, there is a paucity of evidence about the geographic location of earnings management within multinational firms. In this study, we examine where companies manage earnings using a sample of 2,067 U.S. multinational firms from 1994 to 2009. We predict and find that firms with extensive foreign operations in weak rule of law countries have more foreign earnings management than companies with subsidiaries in locations where the rule of law is strong. We also find some evidence that profitable firms with extensive tax haven subsidiaries manage earnings more than other firms and that the earnings management is concentrated in foreign income.

Book-Tax Conformity and the Information Content of Earnings

We examine whether firms hold more cash in the face of tax uncertainty. Because of gray areas in the tax law and aggressive tax avoidance, the total amount of tax that a firm will pay is uncertain at the time it files its returns. The tax authorities can challenge and disallow the firm’s tax positions, demanding additional cash tax payments. We hypothesize that firms facing greater tax uncertainty hold cash to satisfy these potential future demands. We find that both domestic firms and multinational firms hold larger cash balances when subject to greater tax uncertainty. In terms of economic significance, we find that the effect of tax uncertainty on cash holdings is comparable to that of repatriation taxes. Our evidence adds to knowledge about the real effects of tax avoidance and provides a tax-based precautionary explanation for why there is such wide variation in cash holdings across firms.
