The Internal Revenue Service (IRS) has issued Revenue Procedure 2022-34 providing the indexing adjustment for the required contribution percentage. For plan years beginning in 2023, the required contribution percentage is 9.12%, down from 9.61% in 2022.
The affordability calculation can determine whether an individual can afford employer-sponsored health coverage and affect whether the individual would be eligible for a premium tax credit on the health insurance exchanges. This could affect employers that do not use a safe harbor method to determine whether the coverage they offer is affordable to employees.
For plan years beginning in 2023, employer-provided coverage is considered affordable for an employee if the employee required contribution is no more than 9.12% of that employee’s household income. Because applicable large employers generally do not know their employees’ household incomes, there are three safe harbor methods for calculating affordability.
