The ACA Subsidy Cliff Is Back: What It Means for Your Premium

What "the cliff" means

Under the original ACA rules, premium tax credits stop completely at 400% of the federal poverty level (FPL). For 2026 coverage, that line was $62,600 for a single person and $128,600 for a family of four (based on 2025 poverty guidelines). The figures for 2027 coverage are a little higher. One dollar over and the credit is gone.

For older enrollees and people in high-cost states, that can be the difference between a few hundred dollars a month and well over a thousand for the same plan.

Who's hit hardest

• Self-employed people and small business owners whose net income lands just over the line.
• Early retirees ages 50–64, because full-price premiums climb with age.
• Families with variable income, like owner-operators, commission salespeople and travel nurses.
• Anyone in a high-premium area such as rural counties with few carriers.

The repayment risk

Your tax credit is based on an estimate of your income for the coming year. If you earn more than you estimated, you repay the difference when you file. Starting with 2026 coverage, federal law removed the caps that used to limit how much most households had to repay. Cross 400% by surprise and you could owe back the entire year's credit. Estimate carefully and update your application if your income changes.

Legal ways to lower your MAGI

Subsidies are based on modified adjusted gross income, so reducing MAGI can keep you under the cliff. Common ways:

1. Traditional 401(k) or 403(b) contributions through your job.
2. SEP-IRA or Solo 401(k) contributions if you're self-employed.
3. HSA contributions, now available with more Bronze and catastrophic plans starting in 2026.
4. Traditional IRA contributions, if you qualify for the deduction.
5. The self-employed health insurance deduction and other legitimate business expenses.

Work with a tax professional. The goal is an accurate estimate, not a creative one.

If you're over the cliff

• Compare Bronze and HSA plans. The premium gap between tiers matters more without a credit.
• Look at off-exchange and private underwritten plans if you're healthy.
• Check whether you qualify for a catastrophic plan under the hardship exemption.
• Check employer options in the household, including a spouse's plan.
