The 2026 ACA Affordability Jump to 9.96%: What It Means for Your Contribution Strategy

Most compliance changes arrive as bad news. The 2026 update to the Affordable Care Act affordability percentage is one of the rare exceptions, and that is exactly why it deserves a careful look rather than a quick glance.

The IRS set the affordability percentage at 9.96% for 2026, up from 9.02% in 2025. That is the highest the figure has ever been since the employer mandate took effect. For employers with 50 or more full-time and full-time-equivalent employees, the practical effect is that you can ask employees to pay a larger share of their own coverage in 2026 without tripping the affordability rules. Whether you should is a separate question, and one worth thinking through before you lock in next year's contribution strategy.

A quick refresher on what affordability actually controls

If your organization averages at least 50 full-time and full-time-equivalent employees, you are an applicable large employer under the ACA. That means you have to offer coverage that meets two tests to your full-time staff. The coverage has to provide minimum value, and the employee's share of the premium for the lowest-cost self-only plan has to be considered affordable.

Affordability is the part that moves every year. Coverage is affordable if the employee's required contribution for self-only coverage does not exceed a set percentage of their household income. Because employers cannot see household income, the IRS provides three safe harbors you can use instead: the employee's W-2 wages, their rate of pay, or the federal poverty line. Use any one of them correctly and you are protected, regardless of what the employee's actual household income turns out to be.

When the percentage goes up, the dollar amount you can charge employees goes up with it. That is the entire story behind the 2026 change, and it is why it loosens rather than tightens your obligations.

What the higher percentage means in real dollars

The numbers make this concrete. Under the federal poverty line safe harbor, the most common choice for employers who want a single clean number that covers everyone, the 2026 maximum monthly employee contribution lands at roughly $129.89. An employer using the W-2 safe harbor for an employee earning $45,000 could charge up to about $373.50 per month for self-only coverage, compared with roughly $338.25 in 2025. The rate-of-pay safe harbor scales similarly.

The penalties for getting this wrong are not trivial, which is why the safe harbors matter. For 2026, the penalty for failing to offer coverage to at least 95% of full-time employees is $3,340 per affected employee for the year. The penalty for offering coverage that is unaffordable or fails minimum value is $5,010 per affected employee. Those figures climb with your headcount quickly, so the affordability calculation is one of the few compliance details where a small error becomes an expensive one.

The strategic question hiding inside a compliance update

Here is where it gets interesting for a mid-sized employer. The higher threshold gives you room to shift more premium cost onto employees while staying compliant. With health benefit costs rising at their fastest pace in more than a decade, that room is tempting. Many employers will quietly use it.

The trap is treating a compliance ceiling as a target. Just because you can charge an employee close to $130 a month under the poverty line safe harbor does not mean doing so serves your retention goals. For a worker earning $40,000 a year, the difference between a $90 contribution and a $130 contribution is real money, and it lands at the same moment their grocery bill and rent are climbing. Affordability under the law and affordability as your employees experience it are two different things, and the gap between them is where benefits strategy lives.

The better way to use this update is as a planning input, not a license. Run your renewal numbers both ways. See what shifting to the higher allowable contribution would save the company, then weigh that against what it would cost you in goodwill, enrollment, and turnover among your lower-paid staff. Sometimes the savings justify the move. Often they do not, and a smaller adjustment paired with clear communication serves you better.

Where ICHRA fits into the 2026 picture

The affordability change also reshapes the math for employers considering an individual coverage health reimbursement arrangement. An ICHRA can satisfy the employer mandate, but only if the allowance you offer makes a benchmark individual plan affordable under the same 9.96% test. The mechanics are the reverse of a group plan. Affordability is measured by taking the lowest-cost silver plan premium in the employee's area, subtracting your monthly allowance, and checking that what remains falls within 9.96% of income under your chosen safe harbor.

Because the threshold rose, the minimum allowance you need to keep an ICHRA affordable in 2026 is slightly lower than it would have been at last year's percentage. For employers already weighing an ICHRA as a way to control cost and predictability, this nudges the numbers in a favorable direction. It does not change the underlying decision about whether an ICHRA fits your workforce, but it does make the affordability hurdle a little easier to clear.

What to do before your next renewal

Three steps will keep you both compliant and strategic. First, confirm which safe harbor you are using and recalculate your maximum allowable contribution at the 9.96% rate so you know exactly how much headroom you have. Second, model your renewal at your current contribution and at the higher allowable contribution, and look honestly at what each does to your lowest-paid employees, not just your average. Third, if you are exploring an ICHRA, rerun the affordability math at the new percentage before deciding, because the change works in your favor.

The affordability percentage is one of those compliance details that is easy to delegate to a broker or payroll vendor and forget. The 2026 increase is worth a closer look precisely because it hands you flexibility. How you use that flexibility, whether to protect margin or protect your people, says more about your benefits strategy than any single plan design choice.
