IRS audit selection algorithms disproportionately target Black taxpayers

Stanford researchers found that Black taxpayers were audited at 2.9 to 4.7 times the rate of non-Black taxpayers, with the disparity most pronounced among EITC claimants. The IRS confirmed these findings in a May 2023 letter to Congress after an internal review, and multiple outlets corroborated the disparity and its attribution to audit-selection algorithms.
