Protecting Adopting Families from Audits Act This bill requires the Internal Revenue Service (IRS) to submit a written report to the congressional tax committees comparing the audit rate of individual taxpayers who claim the adoption tax credit to the audit rate of those taxpayers who do not claim such credit. The initial report must be submitted not later than the end of 2023 and then annually thereafter through 2036. The IRS must also submit a written report regarding its audit practices for individuals who claim refundable and nonrefundable tax credits.
