This revenue procedure provides the inflation-adjusted maximum dollar amount that may be made newly available for excepted benefit health reimbursement arrangements or other account-based group health plans for plan years beginning after December 31, 2020, and before January 1, 2022. Due to indexing methodology requiring rounding down to the nearest $50 increment, this amount remains $1,800 for the 2021 plan year.
