A new Tax Foundation investigation found major discrepancies in a Government Accountability Office (GAO) corporate tax study. These errors, which resulted in artificially low depictions of corporate tax rates, portray corporations as not paying nearly close enough to their fair share of taxes. The GAO study fails to consider foreign taxes, which cost corporations up to a quarter of domestic income by some accounts. The data set used by the GAO is also difficult to verify, since only data from 2009 is used and not all of the data is made public. Given these and other issues, the Tax Foundation shows that corporations actually pay much more in corporate taxes than is accounted for, even by official government surveys.
