The Affordable Care Act (ACA) introduced premium tax credits (also known as subsidies) to help lower-income households afford health insurance coverage. These subsidies are based on your projected income when you apply for coverage. However, if your actual income turns out to be higher than expected, you may be required to repay some or all of the subsidy when filing taxes.
ACA Subsidy Repayment Calculator
What Is the ACA Subsidy Repayment Calculator?
The ACA Subsidy Repayment Calculator is a simple online tool designed to help you understand how much subsidy you may have to repay when your income exceeds certain limits.
When you receive a subsidy, the government expects your annual income to stay within the limits you reported when applying. If your income increases, your eligibility decreases. The IRS then requires repayment of a portion (or all) of the subsidy based on your final household income as a percentage of the FPL.
Our calculator eliminates guesswork by applying repayment caps set by the ACA and instantly showing:
- Repayment Amount – the subsidy you must return.
- Remaining Subsidy – the amount you still get to keep.
How to Use the ACA Subsidy Repayment Calculator
Using the tool is simple and takes less than a minute. Follow these steps:
- Enter Household Income
Input your total annual household income in the “Household Income” field. This is the amount that determines subsidy eligibility. - Enter Subsidy Received
Type the total premium tax credit (subsidy) you received for the year. This figure is usually available in your tax forms or marketplace records. - Enter Income Limit (% of FPL)
Provide your final household income as a percentage of the Federal Poverty Level (FPL). The calculator accepts values between 100% and 800% of FPL. - Click "Calculate"
The calculator will instantly display:- Repayment Amount – how much subsidy you need to pay back.
- Remaining Subsidy – what you keep after repayment.
- Click "Reset"
If you’d like to start over, simply press “Reset” to clear all fields.
Example Scenarios
Here are some examples to help you better understand how the calculator works:
Example 1: Moderate Income Increase
- Household Income: $45,000
- Subsidy Received: $3,500
- Income Limit: 250% of FPL
Since 250% is within the range where repayment is capped, the calculator limits the maximum repayment to $3,000. You repay $3,000, and keep $500.
Example 2: Higher Income, Above 400% of FPL
- Household Income: $85,000
- Subsidy Received: $6,000
- Income Limit: 420% of FPL
Once income exceeds 400% FPL, the repayment cap no longer applies. You must repay the full $6,000 subsidy.
Example 3: Income Still Within Low Range
- Household Income: $28,000
- Subsidy Received: $2,000
- Income Limit: 180% of FPL
At 180% of FPL, the repayment cap is $1,200. You only repay $1,200, and keep $800.

20 Frequently Asked Questions (FAQs)
1. What is ACA subsidy repayment?
It’s the amount you return to the IRS if your actual income is higher than what qualified you for subsidies.
