Generally, the Affordable Care Act (“ACA”) requires group health plan coverage sponsored by large employers to be “affordable” in order to avoid certain penalties. “Affordability” is based on whether the premium for employee-only coverage is less than a certain percentage of an employee’s household income or an applicable safe harbor amount. In Notice 2019-29, the IRS announced that the affordability percentage for 2020 would decrease to 9.78% from 9.86% in 2019. Employers should note this change as they set premiums for 2020. Notice 2019-29 is available here.
