Credits and deductions gap

The research papers on this page present aggregate estimates of the tax credits and deductions gap—the amount of credits and deductions for which taxpayers are eligible but did not claim, irrespective of whether those taxpayers filed tax returns—the IRS focused on a subset of fully or partially refundable credits for individuals. Papers in this series generally do not undergo the extensive review and editorial process accorded official IRS publications. Instead, these working papers are intended to make results of research available to others and to encourage discussion on a variety of topics. As a result, papers may be occasionally revised or updated.
