What Income Counts For ACA Subsidies?
Quick Answer
ACA subsidies use modified adjusted gross income (MAGI) for the whole tax household: wages, net self-employment income, unemployment, interest, dividends, retirement distributions, and Social Security benefits — projected for the coverage year, not last year's total.
The subsidy formula runs on one number, and most applicants have never calculated it. MAGI is not the paycheck, not the gross, and not last year’s return.
What goes into MAGI?
Modified adjusted gross income for the whole tax household, projected for the coverage year:
| Counts | Does not count |
|---|---|
| Wages and salaries | Child support received |
| Net self-employment income (after expenses) | Gifts and inheritances |
| Unemployment compensation | Supplemental Security Income (SSI) |
| Interest, dividends, capital gains | Loan proceeds |
| Retirement distributions (most) | Pre-tax retirement contributions (they reduce MAGI) |
| Social Security benefits (incl. non-taxable portion) |
The full mechanics of how the number becomes a credit are in the premium tax credit guide.
Why is “net” the key word for the self-employed?
Because the marketplace counts what a Schedule C keeps, not what it collects. A Realtor grossing six figures with substantial legitimate expenses may show a MAGI far below the gross — and MAGI is what prices the subsidy. This cuts both ways: sloppy expense tracking overstates income and shrinks the credit, while the self-employed health insurance deduction interacts with the credit in a genuinely circular calculation. That intersection is exactly where a licensed tax professional belongs in the conversation — brokers are insurance professionals, not tax professionals.
How should variable income be projected?
Deliberately, and in pencil. The projection drives the advance credit, and the credit is reconciled on the federal tax return against actual MAGI — underestimate and part of the advance gets repaid at filing. The working method: project conservatively from a realistic pipeline, then update the marketplace whenever real income diverges, especially after a big closing or a strong quarter. The estimate is a number to manage all year, not a guess to make once.
Frequently Asked Questions
Does self-employment income count before or after expenses?
After. Net self-employment income — gross receipts minus legitimate business expenses — is what flows into MAGI, which is why accurate bookkeeping directly changes subsidy math for 1099 earners.
Does a spouse's income count toward marketplace subsidies?
Yes. MAGI is measured for the entire tax household, including a spouse's wages and the income of dependents required to file a return, even when only one person needs the coverage.
Does last year's tax return set the subsidy?
No. The marketplace asks for a projection of the coverage year's income. Prior returns help build the estimate but the credit is ultimately reconciled against the actual year's MAGI.
What income does not count for ACA subsidies?
Child support received, gifts and inheritances, Supplemental Security Income, and most loan proceeds stay out of MAGI. Pre-tax retirement contributions also reduce it, which can shift subsidy eligibility.
