The 2017 Tax Act generally repealed the corporate AMT, but also permitted corporations to continue claiming a minimum credit for prior year AMT paid. The credit can generally be carried forward to offset corporate tax liability in a later year. The CARES Act eliminates certain limitations that applied to the carryover provision, so that corporations can claim refunds for their unused AMT credits for the first tax year that began in 2018 (i.e., the corporation can take the entire amount of the refundable credit for 2018).
