This document amends the regulations under sections 3111 and 3221 of the Internal Revenue Code with the addition of temporary regulations issued under the regulatory authority granted by the Families First Coronavirus Response Act and the Coronavirus Aid, Relief, and Economic Security Act to prescribe such regulations as may be necessary for reconciling advance payments of refundable employment tax credits provided under these acts and recapturing the benefit of the credits when necessary. Consistent with this authority, these temporary regulations authorize the assessment of any erroneous refund of the credits paid under sections 7001 and 7003 of the Families First Coronavirus Response Act, including any increases in such credits under section 7005 thereof, and section 2301 of the Coronavirus Aid, Relief, and Economic Security Act. The text of these temporary regulations also serves as the text of the proposed regulations (REG-111879-20) set forth in the notice of proposed rulemaking on this subject in the Proposed Rules section of this issue of the Federal Register.
