The Premium Tax Credit alternative calculation for the year of marriage is an optional election that lets each newly married spouse treat one-half of the couple’s combined household income, paired with their pre-marriage family size, as their household income for the months before the wedding. For the marriage months, the standard joint calculation applies. The election exists to prevent the common outcome in which combining two individually eligible incomes on a joint return makes it look like the couple received too much in advance Premium Tax Credit and owes the excess back.1eCFR. 26 CFR 1.36B-4 – Reconciling the Premium Tax Credit With Advance Credit Payments
For 2026 returns the election matters more than it used to. Congress repealed the repayment caps that previously limited how much excess advance credit a lower-income household had to pay back; for tax years beginning after December 31, 2025, every dollar of overpayment is repayable in full.2Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan The enhanced subsidies from the Inflation Reduction Act also expired after 2025, so the 400% federal poverty level cliff is back and two individually eligible incomes can combine into a joint figure that exceeds the ceiling entirely.3U.S. Department of Health and Human Services. 2026 Poverty Guidelines The alternative calculation is the main tool for softening that result.
Who Can Elect It
All five conditions must be met:4Internal Revenue Service. Instructions for Form 8962
- You and your spouse were each unmarried on January 1 of the tax year.
- You were legally married by December 31.
- You file a joint federal return for that year.
- Someone in your tax family was enrolled in a qualified health plan through the Marketplace before your first full month of marriage. If you married on July 15, August is the first full month of marriage, so coverage through July counts.
- Advance credit payments were made for at least one person in your tax family during the year.
Before running the full calculation, confirm that excess advance credits were actually paid. Worksheet 3 in the Form 8962 instructions makes that check. If your advance credits did not exceed the standard credit you qualify for, the alternative calculation changes nothing.4Internal Revenue Service. Instructions for Form 8962
How the Math Works
Under standard reconciliation, the IRS compares your combined annual household income against the federal poverty level for your married household size, and any advance credits above your entitlement come back. The alternative calculation replaces the standard method for the pre-marriage months only.
For those months, each spouse’s household income is treated as one-half of the couple’s actual combined income for the year, and each spouse uses their pre-marriage family size against the poverty guidelines rather than the married household size.1eCFR. 26 CFR 1.36B-4 – Reconciling the Premium Tax Credit With Advance Credit Payments A single person with no dependents uses a family size of one, not two. The combination of a smaller income figure and a smaller family size usually produces a higher allowable credit for those months than the joint math would.
The marriage months are computed the standard way. Your final annual credit is the sum of both spouses’ alternative credit amounts for the pre-marriage months plus the joint credit for the marriage months. The election can only reduce your repayment; it cannot make the result worse than the standard method, so there is no risk in running the numbers.
What You Need Before Starting
Pull everything together first. The worksheets refer back to the same inputs repeatedly.
Form 1095-A. The Marketplace issues this to anyone enrolled in a qualified health plan during the year. It reports monthly enrollment premiums, advance credits paid, and the second lowest cost silver plan (the benchmark) for each month.5HealthCare.gov. How to Use Form 1095-A, Health Insurance Marketplace Statement If each spouse had a separate policy before the wedding, expect two 1095-A forms and keep both.
Modified adjusted gross income for the couple. For PTC purposes MAGI is adjusted gross income plus foreign earned income excluded on Form 2555, tax-exempt interest, and the nontaxable portion of Social Security benefits.6Internal Revenue Service. Modified Adjusted Gross Income Skipping any of those add-backs understates income and produces a wrong credit.
The 2026 federal poverty guidelines. For the 48 contiguous states, 100% of FPL is $15,960 for a household of one and $21,640 for a household of two; Alaska and Hawaii use higher figures.3U.S. Department of Health and Human Services. 2026 Poverty Guidelines You will use both your pre-marriage family size and your married family size at different points in the calculation.
The 2026 applicable percentage table. This gives the share of income each household is expected to contribute toward premiums. For 2026 the percentages run from 2.10% for households below 133% FPL up to 9.96% for households between 300% and 400% FPL.7Internal Revenue Service. Revenue Procedure 2025-25
Form 8962 and Publication 974. Form 8962 is the reconciliation form attached to your return, and Part V is where the election is made. Publication 974 contains the detailed Worksheets I through V that feed figures into Form 8962.8Internal Revenue Service. Publication 974, Premium Tax Credit
Working Through the Worksheets
Publication 974 sets the order.
Worksheet I calculates your alternative monthly contribution amount. Enter half of the couple’s combined household income, apply your pre-marriage family size, and look up your applicable percentage in the IRS table. That produces the monthly amount you would have been expected to contribute toward premiums as an unmarried person. If your spouse also had Marketplace coverage before the wedding, Worksheet III performs the same calculation using your spouse’s pre-marriage family size.8Internal Revenue Service. Publication 974, Premium Tax Credit
Worksheets II and IV convert those contribution amounts into monthly credit figures. Worksheet II handles your pre-marriage months; Worksheet IV handles your spouse’s. Those figures flow into Form 8962, lines 12 through 23, column (e), for each applicable month.9Internal Revenue Service. Instructions for Form 8962
Worksheet V is the check. It compares the total alternative credit against the standard credit and tells you whether the alternative method actually reduces your repayment. If it does not, the worksheet directs you back to the standard method.
When Both Spouses Had Their Own 1095-A
For each pre-marriage month with two policies in force, add the column B amounts (the benchmark plan cost) from both 1095-A forms and enter the combined figure on the relevant Form 8962 line.4Internal Revenue Service. Instructions for Form 8962 If either policy also requires a policy allocation because someone on it is not in your tax family, complete Part IV of Form 8962 before moving into Part V. The instructions specify that order.
Where the Numbers Land on Form 8962
Once the Publication 974 worksheets are done, the alternative monthly credit amounts occupy lines 12 through 23 of Form 8962 for the pre-marriage months; the marriage months use the standard joint figures. Line 29 shows the net excess advance credit for the year. If the election helped, line 29 will be lower than it would have been under the standard method.9Internal Revenue Service. Instructions for Form 8962 Monthly figures need to match your 1095-A documentation exactly; mismatches slow processing.
Filing Jointly Is Required for the Credit
The alternative calculation requires a joint return, and so does the Premium Tax Credit itself for married couples. Filing separately generally forfeits the credit and requires repayment of all advance payments received during the year. Two narrow exceptions let a married person claim the PTC on a separate return:4Internal Revenue Service. Instructions for Form 8962
- You are living apart from your spouse when you file, you cannot file jointly because of domestic abuse or because you cannot locate your spouse after reasonable effort, and you certify this on Form 8962. This relief has a three-year consecutive limit.
- You qualify to file as head of household under the IRS rules for married persons who live apart.
Neither exception is available to couples who simply prefer separate returns.
Report the Marriage to the Marketplace
Marriage opens a 60-day Special Enrollment Period during which you can add a spouse to existing coverage, enroll in a new plan, or change plans.10HealthCare.gov. Special Enrollment Period Reporting the change also updates your advance credit payments to reflect combined income. If advance credits keep flowing at the pre-marriage rate while your combined income is higher, the excess builds all year and comes due at reconciliation. Updating the estimate mid-year is the simplest way to keep the year-end number small, and it works alongside the alternative calculation rather than replacing it.
