The ACA Subsidy Cliff Is Back for 2027: What Older Enrollees Pay

Overview: The Subsidy Cliff Is Back for 2027

The enhanced ACA premium tax credits expired at the end of 2025, and Congress has not renewed them for 2027. That brings back the “subsidy cliff”: earn even $1 over 400% of the federal poverty level and you get no premium tax credit at all. Older enrollees feel it most, because ACA plans can charge a 64-year-old up to three times what they charge a 21-year-old.

For 2027 coverage, the cliff sits at $63,840 for a single person and $132,000 for a family of four, based on the 2026 poverty guidelines.

What Changed When the Enhanced Credits Ended

From 2021 through 2025, temporary federal law lowered what people paid toward a benchmark silver plan and removed the 400% income cap. With those rules gone:

• The 400% cap returned. Above it, you pay the full premium.
• Everyone below it pays a larger share of income. For 2027 the IRS scale runs from 2.15% of income at the low end to 10.22% for households between 300% and 400% FPL (Rev. Proc. 2026-26).
• There is no repayment cap. Starting with 2026 coverage, if your income ends up higher than you estimated, you repay all of the extra advance credit at tax time.

How Big Was the Hit for Older Enrollees?

Before the credits expired, a KFF analysis (October 6, 2025) estimated what people earning $62,700, just over the 2026 cliff, would pay in added premiums for 2026:

Source: KFF. Estimates include the loss of enhanced credits plus the median proposed 2026 rate increase of 18%.

KFF also found that 51% of Marketplace enrollees with incomes above 400% FPL are ages 50 to 64. Many are early retirees or self-employed, with no job-based coverage and no Medicare yet.

A 2027 Example: One Dollar Over the Line

Take two 60-year-olds buying single coverage for 2027:

• Earns $63,800 (just under 400% FPL): pays no more than 10.22% of income, about $6,520 a year, for the benchmark silver plan. The tax credit covers the rest.
• Earns $63,900 (just over 400% FPL): gets no tax credit and pays the full premium, which at age 60 is often far higher.

Ways to Stay Under the Cliff

Subsidy eligibility is based on modified adjusted gross income (MAGI). If you’re close to 400% FPL, these moves can lower it:

1. Contribute to a traditional 401(k) or IRA. Pre-tax contributions reduce MAGI.
2. Use an HSA. HSA contributions are deductible, and every Bronze and Catastrophic Marketplace plan counts as HSA-eligible starting with 2026 coverage. The 2027 limit is $4,500 for self-only coverage ($9,000 family), plus $1,000 if you’re 55 or older.
3. Time capital gains and IRA withdrawals. Early retirees can sometimes shift taxable income into a different year.
4. Update your Marketplace income estimate during the year if your pay changes, so you don’t face a big repayment.

Other Options if You’re Over the Cliff

• Compare metal levels. A bronze plan can cut premiums sharply, but check the deductible. The 2027 ACA out-of-pocket maximum is $12,000 for an individual.
• Look at off-exchange plans if you don’t qualify for a credit; the prices are often similar.
• Check job-based coverage through a spouse or part-time employer.
• See our list of health insurance options for early retirees for the years before Medicare.
• Talk with a licensed agent about your options.

Bottom Line

The subsidy cliff is back for 2027. If you’re in your 50s or early 60s and your income is near $63,840 (single) or $132,000 (family of four), a small change in income can mean thousands of dollars in premiums. Open enrollment runs November 1, 2026 to January 15, 2027 on HealthCare.gov, so estimate your income carefully and compare plans before you renew.
