ACA Group Health Plan Affordability Level Up Sharply

The IRS has significantly increased the group health plan affordability threshold — which is used to determine if an employer’s lowest-premium health plan complies with the Affordable Care Act rules — for plan years starting in 2025.

The threshold for next year has been set at 9.02% of an employee’s household income, up from 8.39% this year. The higher threshold will give employers a little more wiggle room when setting their workers’ premium cost-sharing level for their lowest-cost plans in 2025, to avoid running afoul of the ACA.

Under the ACA, “applicable large employers” — that is, those with 50 or more full-time or full-time equivalent employees (FTEs)— are required to offer at least one health plan to their workers that is considered “affordable” based on a percentage of the lowest-paid employee’s household income.

If an employer’s plan fails this test, it will be deemed as non-compliant with the law, resulting in hefty penalties for the employer.

The new threshold will apply to all health plans whenever they incept in 2025. The affordability test applies only to the portion of premiums for self-only coverage, and not for family coverage.

Also, if an employer offers multiple health plans, the affordability test applies only to the lowest-cost option that provides also minimum value (another ACA plan metric).

Calculating

Employers can rely on one or more safe harbors when determining if coverage is affordable:

• The employee’s most recent W-2 wages, as reported in Box 1.
• The employee’s rate of pay, which is the hourly wage rate multiplied by 130 hours per month (at the start of 2022).
• The federal poverty level.

Employers with a large low-wage workforce might decide to utilize the federal poverty level ($15,060 for 2024) safe harbor to automatically meet the ACA affordability standard, which requires offering a medical plan option in 2025 that costs your full-time employees no more than $113.20 per month.

If an employee’s coverage is not affordable under at least one of the safe harbors and at least one FTE receives a premium tax credit for coverage they purchase on an ACA exchange, the employer may have to pay a penalty, known as the “employer shared responsibility payment.”

The shared responsibility payment for 2025 will be $4,350 per employee that receives a premium subsidy on an exchange, down from $4,460 this year.

The takeaway

As 2025 nears, you should review your health plan costs and premium-sharing to ensure that your lowest-cost plan complies with the affordability requirement.
