You can lose your ACA subsidies mid-year. Changes in income, household, or qualifying coverage can cause subsidy termination. You need to know what triggers this so you don’t end up owing money or losing help when you need it most.
What Are ACA Subsidies & How They Work
ACA subsidies are premium tax credits (also called premium tax credit or PTC) that reduce what you pay for health insurance through the Marketplace. They are based on your estimated income, household size, and the cost of a benchmark plan.
Most people receive these as advance payments (APTC) each month to lower their monthly premium costs. At year’s end, the IRS reconciles what you got vs. what you should have gotten. If your income was higher than estimated, you might need to repay some.
Subsidy eligibility is tied to income bands relative to the federal poverty level. Normally, incomes up to 400% FPL qualify, but due to enhanced subsidies under ARPA/IRA, people above 400% might receive help until 2025.
If the enhanced subsidies are not extended beyond 2025, households above 400% FPL may lose eligibility altogether.
Why Losing ACA Subsidies Mid-Year Happens
You don’t need to wait until renewal. Your subsidies can be cut or dropped during the policy year. Below are the main reasons:
Income Changes That Exceed Projections
If your actual income ends up much higher than what you projected, the subsidy you received may be too large. The IRS will want you to repay the extra.
Starting in 2026, there will be no caps on how much excess subsidy you must repay. So if you under-estimate your income and get too much help, you might owe all of it.

Getting Employer Coverage That’s “Affordable”
Suppose you obtain a job-based plan that meets the IRS rules of affordability and minimum value by mid-year. In that case, you will lose eligibility for Marketplace subsidies for the months you’re eligible.
Any subsidies paid for months after you become subsidy-ineligible can be reclaimed by the IRS.
Changes in Household Composition
If someone moves in or out (birth, divorce, marriage, or someone added), your household size changes. That can push your income per person upward or downward, altering subsidy eligibility.
If your new household income is too high, you might lose subsidies.
Failing to Report Changes in Time
You must report changes (income, household, address) to the Marketplace as soon as they happen. If you don’t, your subsidy may become invalid or be terminated mid-year.
Termination of Enhanced Subsidy Law
Enhanced subsidies (under ARPA / IRA) are set to expire after 2025 unless Congress renews them. If they expire, many who currently get subsidies may lose eligibility.
People with incomes over 400% FPL are especially at risk of losing all help if enhancements are not extended.

What Happens When You Lose ACA Subsidies Mid-Year
Losing subsidies mid-year has effects on your wallet and coverage. Here is what can happen:
- You may have to repay excess subsidies at tax time.
- You may need to pay full premium costs going forward.
- If your coverage is canceled, you risk being uninsured until Open Enrollment or a qualifying event.
- You lose certainty. Budgeting becomes harder.
Premium Tax Credit Repayment Rules
These rules decide how much you might owe if your subsidy was too high.
- If your actual income > projected, you may owe back some of the advanced subsidy (APTC).
- If your income was under 400% FPL, there are caps on how much you must repay.
- In 2026 and beyond, those caps will be removed. All excess APTC must be repaid.
Example: Suppose you estimated your income to be $40,000, got subsidies accordingly, but your actual income is $60,000. You may owe back a large portion.
Another example: You switch mid-year to a job plan. That counts. You lose subsidy eligibility for the months you had employer coverage. You may have to repay.
Who Is at Greatest Risk of Losing Subsidies
Some groups are more vulnerable:
- Middle-income earners near the 400% FPL line. These folks may face the “subsidy cliff” if enhancements end.
- Small business owners and self-employed. Their income can vary more, so projections go wrong.
- People who expect to get employer coverage mid-year.
- Households with changes in composition (marriage, children, etc.).
- Areas with high premium growth: if premium costs rise sharply, the subsidy may no longer be enough.
Mid-Year Tips to Avoid Losing Your ACA Subsidies
Here’s what you can do:
- Update your income estimate when changes happen
Don’t wait until year-end. If your earnings change, log in and update your Marketplace application. - Under-claim subsidy intentionally if the risk is high
You might ask for lower advanced payments to reduce your risk of overpayment and repayment. - Track job changes carefully
If you take a job with employer coverage, check whether it’s “affordable” under ACA rules. If it is, your subsidy eligibility may end. - Watch for the expiration of enhanced subsidy laws
Be prepared if Congress does not renew enhancements after 2025. You may lose some or all of the subsidy. - Save funds in case repayment is needed
Budget for a possible tax liability. - Consult an expert or broker
A subsidy specialist can help you navigate changes and avoid costly mistakes.

FAQs
Will the ACA subsidies expire?
Possibly. The enhanced subsidies are currently set to expire at the end of 2025 unless Congress acts.
What is the cutoff for Obamacare subsidies?
Normally 400% of the federal poverty level (FPL) is the cutoff for subsidy eligibility. But due to enhanced rules, even those above 400% FPL may get help through 2025.
Will I get penalized if I underestimate my income for Obamacare?
You won’t be penalized, but you may have to repay excess subsidy (APTC) when filing your tax return.
How does the ACA subsidy work?
You estimate your yearly income and household size. The subsidy is calculated (as an advance payment to the insurer or via a tax credit). At year’s end, actual income is verified, and the subsidy is reconciled.
