Who it applies to
The percentage matters to an individual deciding whether employer-sponsored minimum essential coverage offered to them is affordable under § 36B. If the required contribution for that coverage comes to more than 9.96% of household income for a plan year beginning in calendar year 2026, the coverage is not affordable for the purposes of that section. It is stated for plan years rather than tax years, so it follows the plan's own year: a plan year beginning inside calendar year 2026 uses 9.96% for its whole run, including months that fall in the next calendar year. The same revenue procedure separately publishes the applicable percentage table for taxable years beginning in calendar year 2026, which is used to calculate the premium tax credit itself.
What changed this year, and why
For plan years beginning in calendar year 2026, the required contribution percentage under § 36B is 9.96%, up from 9.02% for plan years beginning in calendar year 2025. The method behind the adjustment changed as well. For 2025 and a number of years before it, the rate of premium growth was based on per enrollee spending for employer-sponsored insurance as published in the National Health Expenditure Account. Beginning in calendar year 2026, guidance from the Department of Health and Human Services provides a new premium growth measure that also captures increases in individual market premiums, and Treasury and the IRS adopted that measure for both the applicable percentage table and the required contribution percentage. Rev. Proc. 2025-25 states the figure and is effective for taxable years and plan years beginning in calendar year 2026.
Common questions
- What is the ACA affordability percentage for 2026?
- It is 9.96%. Rev. Proc. 2025-25 sets the required contribution percentage under § 36B at 9.96% for plan years beginning in calendar year 2026. That is the share of household income against which an employee's required contribution for employer-sponsored coverage is measured when deciding whether that coverage counts as affordable under the section.
- How did the affordability percentage change from 2025 to 2026?
- It rose from 9.02% for plan years beginning in calendar year 2025 to 9.96% for plan years beginning in calendar year 2026. Because the percentage is the ceiling for what an employee can be asked to contribute before coverage stops counting as affordable, a higher figure means a larger contribution can still be treated as affordable under § 36B.
- Why did the affordability percentage rise so much for 2026?
- Rev. Proc. 2025-25 records a change in how the premium growth measure is calculated. For 2025 and a number of years before it, the rate of premium growth was based on per enrollee spending for employer-sponsored insurance in the National Health Expenditure Account. From calendar year 2026, guidance from the Department of Health and Human Services provides a new measure that also captures increases in individual market premiums, and Treasury and the IRS adopted it.
- Does 9.96% apply to the calendar year or to the plan year?
- To plan years. The revenue procedure sets the required contribution percentage for plan years beginning in calendar year 2026 and is effective for taxable years and plan years beginning in that calendar year. A plan year starting inside calendar year 2026 keeps 9.96% for its whole run, including any months in the following calendar year. A plan year beginning in a different calendar year uses that year's own figure.
- Is the required contribution percentage the same as the applicable percentage table?
- No. They are separate figures in the same document. Rev. Proc. 2025-25 provides indexing adjustments to the applicable percentage table in § 36B for taxable years beginning in calendar year 2026, which is used to calculate an individual's premium tax credit and is arranged by household income as a share of the Federal poverty line. The required contribution percentage decides only whether employer-sponsored coverage is affordable.
- Does the required contribution percentage set the size of my premium tax credit?
- No. It decides only whether employer-sponsored minimum essential coverage counts as affordable, which is a threshold question. The amount of a premium tax credit is worked out from the applicable percentage table in § 36B, which the same revenue procedure publishes for taxable years beginning in calendar year 2026. Both figures come from Rev. Proc. 2025-25 but they answer different questions.
- Was an additional adjustment applied for 2026?
- No. The revenue procedure states that the additional adjustment provided in § 36B is not required for plan years beginning in 2026, because the Treasury Department and the IRS determined that the failsafe exception described in that section applies for plan years beginning in calendar year 2026. The indexing adjustments themselves still use the methodology described in Rev. Proc. 2014-37 and in guidance issued by the Department of Health and Human Services.
- Where is the 2026 affordability percentage published?
- In Rev. Proc. 2025-25, issued by the IRS, which provides the indexing adjustment for the required contribution percentage in § 36B for plan years beginning in calendar year 2026 and supplements Rev. Proc. 2014-37. The revenue procedure is the source for the figure; it is not a projection, and it applies from the start of a plan year rather than from the date it was issued.
The share of household income that makes an offer affordable
An employer's coverage is affordable when the employee's annual cost for self-only coverage does not exceed 9.96% of the household income. This share of income is called the employee required contribution. For 2026, the threshold is set at 9.96%. If the cost for the employee alone is affordable but family coverage costs more than 9.96% of household income, the employee can still take the premium tax credit for other family members who enroll in a Marketplace plan. The test focuses only on self-only coverage when measuring affordability for the employee, not the total cost to cover the entire family.
For 2026, this annual cost threshold will increase to 9.96%.

An affordable offer blocks the premium tax credit
When an employer offers health coverage that qualifies as minimum essential coverage, the employee is considered eligible for an employer-sponsored plan and cannot receive the premium tax credit for a qualified health plan purchased through the Marketplace, but only if two conditions are both met: the employer-sponsored coverage must be affordable, and the coverage must provide minimum value. This means having access to employer coverage alone does not automatically block someone from receiving financial assistance. The offer must pass both the affordability test and the minimum value test. If either test is not satisfied, the employee may still qualify for the premium tax credit despite having an offer of employer coverage. Family members who are eligible to enroll in the same employer coverage face the same two-part test: the coverage must be both affordable and provide minimum value for them to be blocked from receiving the credit.
In addition, if you or your family member en- rolls in the employer coverage that qualifies as MEC, the individual enrolled cannot get the PTC for coverage in a qualified health plan, even if the employer coverage is not affordable or does not provide minimum value.

The second test an employer plan has to fail
An employer health plan must satisfy two separate requirements to block an employee from receiving the premium tax credit: the plan must be affordable and it must provide minimum value. The affordability requirement focuses on whether the employee's premium cost exceeds a percentage of household income. The minimum value requirement is a separate test that the plan must also pass. If a plan fails either test, the employee may qualify for the premium tax credit despite having an offer of employer coverage. The minimum value test examines whether the employer plan covers a sufficient share of total medical expenses for a standard population. When a plan does not meet minimum value standards, it means the coverage is too limited to count as adequate employer-sponsored coverage that would disqualify the employee from Marketplace subsidies.
In addition, if you or your family member en- rolls in the employer coverage that qualifies as MEC, the individual enrolled cannot get the PTC for coverage in a qualified health plan, even if the employer coverage is not affordable or does not provide minimum value.

A waiting period is not coverage you can use
During a waiting period before employer coverage becomes effective, an employee is not considered eligible for that employer coverage. This means the employee can receive the premium tax credit for coverage in a qualified health plan during those months, if otherwise eligible. However, if the employee could have enrolled in employer coverage that is affordable and provides minimum value but chose not to enroll during an available enrollment period, they lose eligibility for the premium tax credit for the rest of that plan year. This rule prevents employees from declining adequate employer coverage during open enrollment and then claiming subsidies for Marketplace coverage. If the enrollment period relates to coverage for multiple plan years and there is no subsequent opportunity to enroll, the employee may regain eligibility for the premium tax credit in those later plan years.
Waiting periods and other periods without access to benefits. You are not considered eligible for employer coverage, and can get the PTC for your coverage in a qualified health plan if you are otherwise eligible, for a month when you cannot receive benefits under the em- ployer coverage (for example, you are in a waiting period before the employer coverage becomes effective).

Which plans are eligible employer-sponsored coverage
Eligible employer-sponsored plans that qualify as minimum essential coverage include several types of health coverage. These are: an employee health plan offered in the group market, whether insured or self-insured; a self-insured group health plan for employees; coverage under certain expatriate health plans for employees; and the Nonappropriated Fund Health Benefits Program of the Department of Defense. These employer-sponsored plans may also include retiree coverage or COBRA continuation coverage. When employer-sponsored plans provide minimum essential coverage, they are referred to as eligible employer-sponsored plans. However, not all employer-sponsored health coverage counts as minimum essential coverage. Coverage limited to excepted benefits - such as stand-alone vision or dental plans, workers' compensation coverage, or coverage for a specified disease or illness - does not qualify as minimum essential coverage and therefore does not block eligibility for the premium tax credit.
Employer-sponsored plans that are MEC are also refer- red to as “eligible employer-sponsored plans.”
