Marketplace health insurance premiums are tax deductible, but with real limits. You can only deduct the share you actually pay after the Premium Tax Credit is applied, and if you take the itemized route, that amount is deductible only to the extent your total medical expenses exceed 7.5% of your adjusted gross income. Self-employed people have a separate, more generous path that skips both hurdles.
Only the Part You Actually Pay Counts
The portion of your premium covered by the Premium Tax Credit is not your expense, so it cannot go into any deduction.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses – Section: Insurance Premiums What matters is the credit you were actually entitled to for the year, not the advance payments the Marketplace sent your insurer month by month. Those two numbers rarely match, because your final income almost never lands exactly on the estimate you gave when you enrolled.
The reconciliation happens on Form 8962 when you file. Take your total annual premium from Form 1095-A, subtract the final allowed Premium Tax Credit from Form 8962, and the difference is what you can treat as a medical expense.
The IRS uses this example: annual premiums total $8,700, the Marketplace paid $4,200 in advance credits during the year, and you paid $4,500 out of pocket. On Form 8962, your actual entitlement turns out to be only $3,600, so you owe $600 back. Your deductible premium is $8,700 minus $3,600, which is $5,100 — more than you actually paid month to month, because the repaid excess is treated as premium you spent.2Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses – Section: Premium Tax Credit
It works the other way too. If your final allowed credit is larger than what was paid in advance, you get the extra back as a refundable credit, but your deductible premium shrinks by that amount.
The 7.5% AGI Floor and Whether Itemizing Is Worth It
Health insurance premiums qualify as medical expenses under Internal Revenue Code Section 213, alongside dental, vision, and qualified long-term care coverage.3Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses But the deduction lives on Schedule A, which means you have to itemize instead of taking the standard deduction.
For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill Itemizing only pays off when your total itemized deductions clear those numbers. Premiums alone rarely do.
Even after you clear that bar, only the portion of your total medical expenses that exceeds 7.5% of your AGI is deductible.5Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses At an AGI of $80,000, the floor is $6,000. If your total medical expenses for the year are $7,500, only $1,500 makes it onto the return.
The floor applies to all your qualifying medical expenses combined, not just premiums. Unreimbursed copays, prescriptions, dental work, and vision care all count toward the total before the 7.5% cut. You report total medical expenses on Line 1 of Schedule A; the deductible amount after the floor lands on Line 4.6Internal Revenue Service. Instructions for Schedule A (Form 1040) (2025)
The Self-Employed Deduction Skips Both Hurdles
If you’re self-employed, you don’t need to itemize and you don’t face the 7.5% floor. You can deduct up to 100% of your health insurance premiums as an adjustment to income on Schedule 1 of Form 1040. Because it reduces AGI directly, it also improves every other calculation on the return that depends on AGI.7Internal Revenue Service. Instructions for Form 7206 (2025) – Section: Self-Employed Health Insurance Deduction
You qualify if you had a net profit on Schedule C or Schedule F, had net self-employment earnings as a partner, or received wages from an S corporation where you were a more-than-2% shareholder. The deduction can’t exceed the net earnings from the business the plan is tied to.
One rule trips people up: you can’t claim the deduction for any month you were eligible to participate in a subsidized employer plan, even if you didn’t enroll. A spouse’s employer offering family coverage you could have joined disqualifies those months, even when you bought your own Marketplace plan instead.8Internal Revenue Service. Instructions for Form 7206 (2025) – Section: Other Coverage
When advance premium tax credits are in the picture, the self-employed deduction and the PTC feed into each other. Your deduction lowers AGI, which changes the allowed PTC, which changes the deductible premium, which changes the deduction. The IRS directs filers to Publication 974 for that iterative calculation. Any premium you can’t deduct through the self-employed route can still go onto Schedule A with your other medical expenses.9Internal Revenue Service. Topic No. 502, Medical and Dental Expenses
What Changed for 2026
Two shifts make the numbers less forgiving this year. The enhanced Premium Tax Credit provisions that ran from 2021 through 2025 expired on January 1, 2026. For 2026, household income has to fall between 100% and 400% of the federal poverty level to qualify for any credit. For a single person in the contiguous 48 states, 400% of the 2026 poverty guideline is about $63,840.10U.S. Department of Health and Human Services, Office of the Assistant Secretary for Planning and Evaluation. 2026 Poverty Guidelines Earn more and you get no credit at all. Required contribution percentages also went up at every income tier.11Congress.gov. Enhanced Premium Tax Credit and 2026 Exchange Premiums
The other change is the repayment cap. Before 2026, if your income came in higher than expected and you had to pay back excess advance credits, the amount you owed was capped by income level. Those caps are gone. For tax years beginning after December 31, 2025, you repay the full excess regardless of income.12Internal Revenue Service. Updates to Questions and Answers About the Premium Tax Credit13Internal Revenue Service. One, Big, Beautiful Bill Provisions
The practical effect on the deduction is that many people will have larger out-of-pocket premiums in 2026, and that larger amount is at least eligible to go into the medical expense calculation if you itemize. If you expect income swings during the year, consider taking less credit in advance and claiming the rest at filing, because a full-freight repayment with no cap can be substantial.
HSA Funds Won’t Cover the Premium
If you have a Health Savings Account, you cannot use it to pay ordinary Marketplace premiums. The IRS limits HSA distributions for insurance premiums to four situations: COBRA continuation coverage, health premiums while receiving unemployment compensation, Medicare premiums at 65 or older (not Medigap), and long-term care insurance subject to age-based limits.14Internal Revenue Service. Publication 969 (2025), Health Savings Accounts and Other Tax-Favored Health Plans – Section: Insurance Premiums Using HSA money for a regular Marketplace premium is a non-qualified distribution, taxable and subject to a 20% penalty if you’re under 65.
Forms You’ll Need
Form 1095-A arrives from the Marketplace by January 31 and has the numbers you need: monthly enrollment premiums, the benchmark second-lowest-cost silver plan premium, and how much advance credit was paid.15Internal Revenue Service. About Form 1095-A, Health Insurance Marketplace Statement
Form 8962 is required for anyone who received advance premium tax credit payments, itemizing or not. You have to file it with your return even if you’d otherwise not be required to file.16Internal Revenue Service. Instructions for Form 8962 (2025) Skipping it doesn’t only delay a refund. The IRS will block you from receiving advance credit payments or cost-sharing reductions the following year, and people sometimes learn about that only when the next year’s premium arrives at full price.17Internal Revenue Service. Reconciling Your Advance Payments of the Premium Tax Credit
Schedule A comes in only if you’re itemizing. Self-employed filers using the above-the-line deduction report it on Schedule 1 and show the calculation on Form 7206.
