    Taxing Multinational Corporations:

                  Average Tax Rates


       MELISSA COSTA* AND JENNIFER GRAVELLE**


                          I. INTRODUCTION
  As other countries, most recently the United Kingdom, have moved
to territorial tax systems, questions about the potential for the United
States to move to a territorial tax have become topics of interest. Key
to making informed decisions on options for changing the tax treat-
ment of foreign corporate income is a greater understanding of the
taxes U.S. multinational corporations actually pay.
  This Article is a continuation of a previous analysis that used a new
tax data source to provide more comprehensive estimates of average
tax rates (ATRs) on foreign and domestic income of U.S. corpora-
tions. The analysis we undertake in this Article is an extension of an
earlier report by the Government Accountability Office.1 That report
provided descriptive statistics on multinational corporations' activities
and tax rates they faced. Previously we provided ATRs of U.S. con-
trolled foreign corporations (CFCs)2 incorporated in different coun-
tries.3 This Article expands on both prior works by including
estimates of the ATRs of U.S. CFCs by industry and by providing
updated estimates of U.S. ATRs on foreign and domestic income of
multinational corporations. We employ a similar methodology with
some refinements in the measures of domestic and foreign income.
Details on our methodology and how it differs from the GAO report
are provided in the Appendix.

corporation's tax year) U.S. shareholders own more than 50% of its outstanding voting
stock, or more than 50% of the value of all its outstanding stock, and individually own at
least 10%. IRC §§ 951(b), 957.
