The Internal Revenue Service today issued guidance for employers claiming the employee retention credit under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), as modified by the Taxpayer Certainty and Disaster Tax Relief Act of 2020 (Relief Act), for calendar quarters in 2020. The guidance in Notice 2021-20 PDF is similar to the information in the employee retention credit FAQs, but includes clarifications and describes retroactive changes under the new law applicable to 2020, primarily relating to expanded eligibility for the credit.
