ACA Income & Subsidies
Household income is an important part of determining eligibility for financial assistance through the ACA Marketplace.
What income counts — and why your estimate matters
QUICK ANSWER
Which Year's Income Does the ACA Marketplace Use?
Marketplace savings are generally based on your expected household income for the year you want health coverage.
This means the Marketplace does not simply use last year's income to determine your financial assistance.
Your previous tax return can be useful when making an estimate, but you should consider what you realistically expect your household income to be during the coverage year.
HOW ACA SUBSIDIES WORK
How Is Your ACA Premium Tax Credit Determined?
Your ACA subsidy is not based on income alone. The Marketplace uses several pieces of information to determine whether you may qualify for a Premium Tax Credit and how much assistance may be available.
1. Household
Your tax household and family size are important because Marketplace financial assistance is generally based on household information.
2. Expected Annual Income
The Marketplace uses your expected household income for the coverage year, not simply what you earned last year.
3. Federal Poverty Level
Household income is compared with the applicable Federal Poverty Level (FPL) for your family size. This is one factor used in determining eligibility for the Premium Tax Credit.
4. Other Coverage
Eligibility can also depend on whether household members have access to qualifying coverage through an employer or certain government programs.
5. Marketplace Plan Costs
The amount of the Premium Tax Credit also depends on Marketplace plan costs used under the federal Premium Tax Credit calculation. Because plan premiums vary by location and age, two households with the same income may not necessarily receive the same Premium Tax Credit.
6. Your Premium Tax Credit
If you are eligible, you may choose to have all, some, or none of your estimated Premium Tax Credit paid in advance to the insurance company to reduce the monthly premium you pay.
Important:
A Premium Tax Credit is not simply a fixed percentage of your income. Household information, income, eligibility for other coverage, and Marketplace plan costs can all affect the result.
WHY INCOME MATTERS
Your Situation May Be Different This Year
Income can change significantly from one year to another. This is especially important when applying for Marketplace coverage.
Lost a Job
Someone who recently lost a job may expect substantially less income during the coverage year than they earned the previous year.
Changed Jobs
A new salary, employment gap, bonus, or other compensation change may affect expected household income.
Retired Early
Someone retiring before Medicare may have little or no wage income but may still have retirement withdrawals, Social Security, investment income, or other income.
Self-Employed
Business income may vary from year to year, making a reasonable current-year estimate especially important.
UNDERSTANDING MAGI
What Is MAGI?
The ACA Marketplace generally uses Modified Adjusted Gross Income (MAGI) when determining income-based eligibility for Marketplace savings.
For many people, Marketplace MAGI is the same as or very close to the Adjusted Gross Income (AGI) shown on their federal income tax return.
For Marketplace purposes, certain amounts may need to be added to AGI, including tax-exempt interest, non-taxable Social Security benefits, and excluded foreign earned income.
Simple way to think about it:
Marketplace MAGI generally starts with your federal Adjusted Gross Income and adds certain types of income required under Marketplace rules.
WHAT INCOME COUNTS?
Examples of Income for ACA Marketplace Purposes
The following table provides general examples. Individual tax and Marketplace situations can be more complicated.
| Generally counts | Examples that generally don't count |
|---|---|
| Federal taxable wages and salary | Child support received |
| Net self-employment income | Gifts |
| Unemployment compensation | Loan proceeds |
| Capital gains | Supplemental Security Income (SSI) |
| Investment interest and dividends | Veterans' disability payments |
| Net rental and royalty income | Workers' compensation |
| Taxable IRA and 401(k) withdrawals | Qualified distributions from a designated Roth account |
| Pension income | Child Tax Credit payments |
| Social Security income, including non-taxable Social Security | Certain alimony from divorces finalized on or after January 1, 2019 |
This table is a general educational summary and should not be used as individual tax advice. Income treatment can depend on the type of income and your specific circumstances.
INVESTMENT INCOME
Do Capital Gains, Interest and Dividends Count?
Capital gains, investment interest, and dividends can be included when estimating Marketplace income.
This can be especially important for people who receive a significant portion of their income from investments rather than wages.
Important distinction:
Selling $50,000 of stock does not necessarily mean you have $50,000 of capital gain. The taxable gain and the total sale proceeds are different concepts.
RETIREMENT INCOME
Retiring Before Medicare?
People who retire before becoming eligible for Medicare may use the ACA Marketplace for health insurance coverage.
Having no salary does not necessarily mean having no Marketplace income.
Depending on your circumstances, Marketplace income may include sources such as:
- Pension income
- Taxable traditional IRA withdrawals
- Taxable 401(k) withdrawals
- Social Security benefits
- Interest and dividends
- Capital gains
- Other applicable income
Example:
Someone may retire with $0 in wages but still have substantial Marketplace household income from retirement withdrawals and investments.
HOUSEHOLD INCOME
It's Not Always Just the Applicant's Income
Marketplace financial assistance is generally based on household income rather than simply the income of the person who needs health insurance.
Your Marketplace household generally includes the tax filer, spouse, and tax dependents, although the exact rules depend on the household and tax situation.
Income from tax dependents generally counts toward Marketplace household income when the dependent is required to file a federal income tax return because their income meets the filing threshold. A dependent who files only to claim a refund generally does not have that income counted for this purpose.
TAX FILING STATUS
Married? Tax Filing Status Can Matter
In general, married taxpayers must file a joint federal income tax return to qualify for the Premium Tax Credit.
Limited exceptions can apply in certain circumstances, including specific rules involving domestic abuse or spousal abandonment.
Tax filing situations can be complex. Consider consulting a qualified tax professional when you have questions about your individual tax situation.
INCOME CHANGED?
Update Your Marketplace Application
Your income estimate is not something you should necessarily set once and ignore for the rest of the year.
If your income or household circumstances change, update your Marketplace application as soon as possible.
Changes can affect the amount of financial assistance for which you are eligible.
Examples of changes:
Starting or losing a job, receiving a raise, changing household size, retiring, or experiencing a significant change in self-employment or investment income.
PREMIUM TAX CREDIT
Why Does the Income Estimate Matter at Tax Time?
If you qualify for a Premium Tax Credit, you may be able to use some or all of the estimated credit in advance to reduce your monthly Marketplace premium.
After the year ends, the advance Premium Tax Credit is reconciled with the credit you actually qualify for based on your final information.
This reconciliation is generally completed using IRS Form 8962 when filing your federal income tax return.
This is one reason it is important to provide a reasonable income estimate and report significant changes during the year.
Important for 2026 and later:
For tax years after 2025, federal rules no longer provide the previous repayment caps for excess Advance Premium Tax Credit. If the advance credit paid during the year is more than the Premium Tax Credit you are actually allowed, the full excess generally must be repaid through your federal income tax return.
CURRENT ACA RULES
Income Is Important, but It Isn't the Only Factor
Premium Tax Credit eligibility depends on household income relative to the applicable Federal Poverty Level, along with other eligibility requirements.
For current coverage years, federal rules should always be checked because subsidy rules can change from one year to another.
Other factors can also affect eligibility, including access to qualifying employer-sponsored coverage, eligibility for certain government programs, household composition, tax filing status, and other Marketplace requirements.
Important:
Being below a particular income number does not automatically guarantee that you qualify for an ACA Marketplace subsidy.
FEDERAL POVERTY LEVEL
How Does FPL Relate to ACA Subsidies?
Federal Poverty Level (FPL) figures are used as part of determining eligibility for certain ACA Marketplace financial assistance.
FPL amounts depend on household size and the applicable federal guidelines.
On the next page, you can see approximate FPL income figures to help understand how these percentages work.
