To our knowledge, this paper provides the most comprehensive analysis of firm-level corporate income taxes to date. We use publicly available financial statement information for 11,602 public corporations from 82 countries from 1988 to 2009 to estimate country-level effective tax rates (ETRs). We find that the location of a multinational and its subsidiaries substantially affects its worldwide ETR. Japanese firms always faced the highest ETRs. U.S. multinationals are among the highest taxed. Multinationals based in tax havens face the lowest taxes. We find that ETRs have been falling over the last two decades; however, the ordinal rank from high-tax countries to low-tax countries has changed little. We also find little difference between the ETRs of multinationals and domestic-only firms....

To our knowledge, this paper provides the most comprehensive analysis of firm-level corporate income tax expenses to date. We use publicly available financial statement information to estimate firm-level effective tax rates (ETRs) for 10,642 corporations from 85 countries from 1988 to 2007. We find that multinationals and domestic-only companies face similar ETRs. We also find that, on average, ETRs declined by seven percentage points or 20% over the period. German, Japanese, Australian and Canadian decreases were large. American, British, and French declines were more modest. Nonetheless, because ETRs were falling worldwide, the ordinal rank from high-tax countries to low-tax countries changed little. Japanese firms always faced the highest ETRs. ETRs for tax havens and countries ...
