On May 21, 2018, the IRS issued Revenue Procedure 2018-34 to index the contribution percentages in 2019 for purposes of determining affordability of an employer’s plan under the Affordable Care Act. These updated affordability percentages are effective for taxable years and plan years beginning Jan. 1, 2019. This is a significant increase from the affordability contribution percentages for 2018. As a result, some employers may have additional flexibility with respect to their employee contributions for 2019 to meet the adjusted percentage.
