Freelancing, consulting, or running a small side business after leaving a full-time job changes how Medicare premiums can be handled at tax time, because they no longer have to count as an ordinary personal expense. The self-employed health insurance deduction lets that retiree subtract the premiums directly from income before reaching taxable income, the same treatment given to any other self-employed worker’s health coverage. The break is easy to miss because the IRS discontinued the publication that used to spell out the rules, and the paperwork now runs through a form most retirees have never seen.
Form 7206 Replaced the Worksheet Buried in a Retired IRS Publication
For years, the self-employed health insurance deduction was calculated on a worksheet tucked into Publication 535, Business Expenses. The IRS discontinued that publication after the 2022 tax year and moved the calculation onto its own form, Form 7206, Self-Employed Health Insurance Deduction. The math still lands in the same place it always did: a self-employed retiree figures the deduction on Form 7206, then carries the total to Schedule 1 of Form 1040, line 17, where it lowers income before the standard or itemized deduction is applied. Because the write-off is claimed on Schedule 1 rather than Schedule A, a retiree does not need to itemize to use it, and it is available whether or not medical costs clear the separate 7.5%-of-income floor that limits itemized medical deductions. A retiree who still has medical bills left over after the deduction can carry those onto Schedule A if they itemize, as long as the same dollars are not counted twice.

Which Medicare Premiums Actually Qualify
The deduction is not limited to a single Medicare premium. IRS instructions for Form 7206 state that Medicare premiums a taxpayer voluntarily pays for coverage similar to qualifying private health insurance can be used to figure the deduction, and that description covers more than one part of the program. Part B premiums, the ones most retirees pay every month, qualify. So do Part A premiums for a retiree who has to buy that coverage because of insufficient work history, Part C Medicare Advantage premiums, Part D prescription drug premiums, and Medigap supplemental premiums. A retiree who pays premiums covering a spouse can generally include those amounts too, since the underlying deduction is written to cover a taxpayer, a spouse, and dependents together. A retiree with more than one health plan established under different businesses during the year has to figure each plan’s limit on its own form, rather than combining everything onto a single calculation.
Qualifying Is Not Automatic, and the Deduction Has Real Ceilings
The instructions attach specific conditions. A retiree must have net profit from self-employment reported on Schedule C or Schedule F, be a partner with net earnings from self-employment reported on a Schedule K-1, or be a more-than-2%-shareholder in an S corporation receiving wages tied to the premiums, and the coverage must be established under that business. A retiree cannot use the deduction for any month in which they were eligible to participate in a subsidized health plan through a spouse’s employer, even if they never enrolled in it. The deduction also cannot exceed the net profit generated by the business under which the coverage is established, a real constraint for a retiree whose consulting income is modest next to the combined cost of a Medicare Advantage premium, a Medigap policy, and a Part D plan. A retiree layering in qualified long-term care insurance faces its own ceiling on top of that, one that scales with age from $480 a year for someone 40 or younger up to $6,020 for someone 71 or older, based on age at the end of the tax year.
The Break Lowers Income Tax, Not Self-Employment Tax
The savings apply only to income tax, not to the Social Security and Medicare taxes a self-employed retiree still owes on business earnings. Form 7206’s instructions specifically bar a retiree from subtracting this deduction when figuring net earnings for self-employment tax on the business under which the coverage is established, so the premiums still count toward the base that determines Social Security and Medicare tax due for the year. A retired public safety officer has a separate, narrower break available instead: up to $3,000 in retirement-plan distributions used directly to pay health or long-term care insurance premiums can be excluded from income outright, but those same dollars cannot also be run through the self-employed health insurance deduction on the same return. Keeping the premium statements and proof of net profit on file matters, since the deduction is capped by whichever business earnings figure the retiree ultimately reports.
Because It Lowers AGI, the Deduction Can Ease Two Other Costs Too
Unlike an itemized medical expense claimed on Schedule A, the self-employed health insurance deduction is taken directly on Schedule 1 and reduces adjusted gross income itself, which gives it reach beyond the immediate tax bill. Social Security uses a measure called “combined income,” equal to adjusted gross income plus tax-exempt interest plus half of a retiree’s annual benefit, to decide whether up to 50% or 85% of Social Security benefits get taxed at all, according to the Social Security Administration’s guidance on taxation of benefits; taxes apply once combined income passes $25,000 for an individual filer or $32,000 on a joint return. Because the Medicare premium deduction subtracts directly from AGI, a self-employed retiree sitting close to one of those lines can lower combined income enough to keep more of a Social Security check untaxed.
The same AGI reduction can help avoid a second, separate cost: Medicare’s income-related monthly adjustment amount, or IRMAA, which raises Part B and Part D premiums for higher earners. Medicare bases IRMAA on modified adjusted gross income, defined by Social Security’s own program manual as AGI plus tax-exempt interest, measured from a tax return filed one to two years earlier. For 2026, that surcharge begins once modified adjusted gross income passes $109,000 for most filing statuses or $218,000 for a married couple filing jointly, per the agency’s published MAGI thresholds. A self-employed retiree whose income sits near either line has a genuine incentive to claim the full Medicare premium deduction available, since every dollar it removes from AGI is a dollar that can no longer push that year’s Medicare premiums into a higher surcharge bracket two years later.
