Tax Administration: Comparison of the Reported Tax Liabilities of Foreign- and U.S.-Controlled Corporations, 1996-2000

In prior reports, GAO found differences in the percentages of foreign-controlled corporations (FCC) and U.S.-controlled corporations (USCC) reporting no tax liability. Based on concerns that FCCs could be avoiding taxes by improperly shifting income to lower tax countries, GAO was asked to compare, for the years 1996 through 2000, (1) FCCs and USCCs, based on the tax liabilities they reported on their U.S. income tax returns--including the percentages reporting zero liabilities--and (2) the differences in FCCs and USCCs in terms of age and industry concentration and the extent to which these differences might explain tax reporting patterns. The report provides information separately for large corporations--those with at least $250 million in assets or $50 million in gross receipts--because, while they account for only 1 percent of all corporations, they own over 93 percent of all assets reported on corporate returns.
