If you receive health insurance through Covered California or the Health Insurance Marketplace, 2026 brings an important change: the enhanced ACA subsidies that were available from 2021 through 2025 have expired, and the income limits for subsidy eligibility have returned.
Understanding how ACA subsidies work can help you avoid unexpected tax bills and prepare for your 2027 health insurance renewal.
ACA Subsidies Are an Advance Tax Credit
Your monthly subsidy is not a discount from the insurance company. It is an Advance Premium Tax Credit (APTC) paid by the government based on your estimated household income.
At the end of the year, the IRS compares:
- The income you estimated when you enrolled
- Your actual income reported on your tax return
If your income is higher than expected, you may have to repay some or all of the subsidy. If your income is lower, you may receive an additional tax credit.
Report Income Changes Promptly
One of the biggest reasons taxpayers face ACA repayment surprises is failing to update their income during the year. Common events that can affect your subsidy include:
- Pay raises and bonuses
- Self-employment income increases
- Stock option exercises
- Capital gains
- Roth conversions
- Rental income
- Retirement distributions
If your income changes significantly, update Covered California or the Marketplace as soon as possible so your subsidy can be adjusted.
2026 ACA Income Limits
For 2026 coverage, premium tax credits are generally available only for households with income between 100% and 400% of the Federal Poverty Level (FPL). The subsidy cliff has returned for households above 400% of FPL.
| Household Size | Approximate 400% FPL Limit |
|---|---|
| 1 Person | $62,600 |
| 2 People | $84,600 |
| 3 People | $106,600 |
| 4 People | $128,600 |
What Happens if Your Income Exceeds the Limit?
Under the restored rules, households with income above 400% of FPL generally are not eligible for premium tax credits. If you received subsidies during the year and your income ultimately exceeds the eligibility limit, you may:
- Lose subsidy eligibility
- Have to repay some or all of the advance subsidy received
- See a reduction in your tax refund or owe additional tax
- Face higher premiums when renewing coverage for 2027
Year-End Planning Matters
If your income is close to one of these thresholds, proactive tax planning may help preserve subsidy eligibility. Potential strategies include:
- Maximizing retirement plan contributions
- Contributing to an HSA
- Reviewing capital gains and losses
- Evaluating Roth conversion timing
- Managing self-employment income and deductions
Final Takeaway
The ACA subsidy is one of the most valuable tax benefits available to many families, but it can also create unexpected tax bills when income changes are not reported. With the return of the subsidy cliff in 2026, monitoring your income throughout the year is more important than ever.
If you have Marketplace coverage and your income fluctuates, consider a year-end tax projection before open enrollment. A little planning can help you avoid a large subsidy repayment and make more informed decisions for your 2027 coverage.
