Americans pay about 83.6% of their federal taxes in full and on time. After enforcement efforts are considered, the estimated share of taxes ultimately paid is 85.8%, leaving a $381 billion annual net gap between taxes owed and taxes collected, according to an Internal Revenue Service study.

While the estimated gross tax gap for individual income tax is $314 billion, the tax gap for corporate income tax is $42 billion on average for the years 2011 to 2013, the IRS said.
