On Sept. 6, 2024, the IRS released Revenue Procedure 2024-35 to index the contribution percentage in 2025 for determining the affordability of an employer’s plan under the Affordable Care Act (ACA). For plan years beginning in 2025, employer-sponsored coverage will be considered affordable under the ACA’s “pay-or-play” rules if the employee’s required contribution for self-only coverage does not exceed 9.02% of their household income for the year.
