Frequently Asked Questions

1. What information do I need to calculate ACA affordability for employees?

You generally need the lowest-cost self-only health plan premium that provides minimum value, along with the employee information required for the selected safe harbor. GoBenefits’ calculator uses information such as the Federal Poverty Level, hourly rate of pay, and annual W-2 wages to estimate the maximum employee contribution and required employer contribution.

For 2026, the ACA required contribution percentage is 9.96%. The maximum affordable employee contribution depends on the safe harbor method being used, along with the applicable employee wage or Federal Poverty Line information. The GoBenefits calculator can help estimate the maximum monthly employee contribution under each safe harbor.

For hourly employees, the ACA Rate of Pay safe harbor generally uses the employee’s hourly rate of pay multiplied by 130 hours per month to determine the applicable monthly rate of pay. The applicable ACA affordability percentage is then used to determine the maximum amount the employee can be required to contribute toward self-only health coverage. 

The W-2 safe harbor determines ACA affordability using an employee’s wages reported in Box 1 of Form W-2. The applicable ACA affordability percentage is applied to the employee’s W-2 wages to determine the maximum affordable employee contribution toward self-only coverage that provides minimum value. 

Changes in an employee’s wages or hourly rate may affect ACA affordability, depending on the safe harbor method being used. Employers should review applicable changes under the Rate of Pay safe harbor and W-2 safe harbor and maintain accurate employee compensation and benefits information. Regularly reviewing these changes can help employers monitor ACA affordability requirements and compliance and identify potential issues with employee contributions.

Employers should review ACA affordability as part of their ongoing benefits and ACA compliance process, particularly when employee pay, plan premiums, or other relevant coverage details change and when preparing for a new plan year.

Yes. An ACA affordability calculator can help employers evaluate whether employee contributions meet applicable ACA affordability requirements under an eligible safe harbor. Reviewing these calculations can help employers identify potential affordability issues and take corrective action before they create greater compliance risk. 

GoBenefits also provides broader ACA compliance support, including affordability and eligibility management, payroll data integration, and 1094-C and 1095-C reporting support.
