Choosing a health insurance plan through the Marketplace can come with big savings, but it also comes with some important financial details to understand. One of the most important? How premium tax credits work and what happens if your income doesn’t match what you originally estimated.

If you’re receiving financial help to lower your monthly premium, here’s what you need to know for 2026—and a major change coming in 2027 that could impact how repayment works.


What Are Premium Tax Credits (APTC)?

Premium tax credits (also called Advanced Premium Tax Credits, or APTC) are designed to make Marketplace health insurance more affordable.

When you apply for coverage, you estimate your household income for the year. Based on that estimate, the Marketplace calculates a subsidy to help lower your monthly premium—and that amount is paid directly to your insurance company.


This means you pay less each month!

But the credit is based on an estimate, not your final income.

Why Repayment Happens

At the end of the year, the IRS compares:

  • The income you estimated when enrolling, and

  • The income you actually earned


If your income ends up being higher than expected, you may have received more tax credit than you qualified for. This difference is reconciled when you file your federal taxes.

In some cases, you may need to pay back a portion—or all—of the excess credit.


Repayment Limits for 2026

For the 2025 coverage year (filed with your 2026 taxes), repayment limits are still based on your income as a percentage of the Federal Poverty Level (FPL).


Here’s how repayment caps are structured:

Household Income (as % of FPL)

Individual Cap

Family Cap

Less than 200% of FPL

$375

$750

200% – 300% of FPL

$950

$1,900

300% – 400% of FPL

$1,600

$3,200

Above 400% of FPL

No cap

No cap

Important: If your income exceeds 400% of the Federal Poverty Level, there is currently no limit on how much excess APTC you may have to repay—you could owe the full amount.


Big Change Coming in 2027

Starting in 2027, repayment rules are expected to change significantly:


There will be no repayment caps at any income level.


This means that regardless of your income, if you receive more premium tax credit than you qualify for, you may be required to repay the full excess amount.

This change makes it more important than ever to keep your income estimates accurate throughout the year.


How to Avoid Paying Back Too Much

The best way to avoid an unexpected tax bill is to stay proactive:


1. Update Income Changes Quickly

If your income changes—new job, raise, fewer work hours, or added income—report it to the Marketplace as soon as possible.


2. Be Thorough With Your Estimate

Include all sources of income:

  • Wages

  • Self-employment or side gigs

  • Bonuses and commissions

  • Unemployment or other benefits


3. Do a Mid-Year Check-In

Halfway through the year, compare your actual income to your estimate. If things have changed, update your application.


4. Consider Taking Less Subsidy

If your income is unpredictable, you can choose to take less APTC each month and reduce the risk of repayment later.

What If You Do Have to Repay?

If you received too much APTC, the IRS will add the excess amount to your tax bill when you file.

If paying it all at once isn’t feasible, the IRS offers payment plan options to spread out the cost.


The Bottom Line

Premium tax credits are a powerful way to make health insurance more affordable—but they require careful attention throughout the year.


With repayment limits still in place for 2026—and potentially disappearing in 2027—accurate income reporting and regular updates are more important than ever.

Staying on top of your numbers now can help you avoid costly surprises later.
