IRMAA is tax deductible in the same way any Medicare Part B or Part D premium is: the IRS treats the surcharge as part of your premium, which qualifies as a medical expense under Internal Revenue Code Section 213.1Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses Whether you actually save any tax from that classification is a different question, and for most people who pay IRMAA the answer is no. The itemized medical deduction has two barriers built into it that high-income filers rarely clear. Self-employed retirees have a much better path, and anyone with a Health Savings Account has a third option worth knowing about.
Why the Itemized Deduction Usually Falls Short
To claim IRMAA on Schedule A, two conditions have to line up. First, only the portion of your total medical expenses that exceeds 7.5% of your adjusted gross income counts.1Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses Second, your combined itemized deductions have to beat the standard deduction, which for 2026 is $16,100 for single filers and $32,200 for joint filers.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
The problem is circular. IRMAA only applies to people with high incomes, and high incomes create a high 7.5% floor. Take a single filer with $160,000 in AGI. Their floor is $12,000, so the first $12,000 of medical costs deducts nothing. If that person pays $4,870 in Part B premiums (base plus IRMAA), $1,200 in Part D, and $6,000 in other medical bills, they total $12,070. Only $70 crosses the threshold. That $70, plus their state taxes and any other itemizables, then has to beat the $16,100 standard deduction to matter at all.
Scale that up and the math gets worse. A married couple filing jointly with $400,000 in AGI faces a $30,000 floor before a single dollar becomes deductible. IRMAA is a qualified medical expense in the code’s eyes; for most people paying it, the deduction delivers nothing.
The Self-Employed Above-the-Line Deduction
If you have net self-employment income, the picture changes completely. Under IRC Section 162(l), self-employed individuals can deduct health insurance premiums directly on Schedule 1 of Form 1040.3Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses This is an above-the-line deduction, meaning you don’t itemize and you don’t face the 7.5% floor. It cuts your AGI dollar for dollar.
Medicare premiums qualify, and because IRMAA is part of your premium, the entire amount you pay is eligible. The IRS instructions for Form 7206 confirm that Medicare premiums you voluntarily pay can be used to figure the deduction.4Internal Revenue Service. 2025 Instructions for Form 7206 – Self-Employed Health Insurance Deduction
To qualify, you need net earnings from a Schedule C, Schedule F, partnership K-1, or wages from an S corporation where you own more than 2% of the shares. The deduction can’t exceed your earned income from that business. And you can’t claim it for any month you were eligible to participate in a subsidized employer health plan through your own work or a spouse’s employer.4Internal Revenue Service. 2025 Instructions for Form 7206 – Self-Employed Health Insurance Deduction
One coordination rule: any premium amount you deduct under Section 162(l) cannot also be counted toward your itemized medical expenses.3Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses No double-dipping. Since the above-the-line route is almost always more valuable, that tradeoff works in your favor. Retirees with consulting income, board fees, or a side business generating net profit should check this deduction before assuming IRMAA is just a cost they absorb.
Paying IRMAA With HSA Funds
Once you turn 65, HSA distributions can cover Medicare premiums tax-free. IRS Publication 969 lists “Medicare and other health care coverage if you were 65 or older” as a qualified medical expense for HSA purposes, with only Medigap policies excluded.5Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans Because IRMAA is an adjusted premium rather than a separate charge, it falls under the same rule as the base premium.
Tax-free distributions aren’t income, so this is effectively a deduction with no floor and no itemization requirement. The account holder must be 65 or older. If you’re under 65 and your spouse is on Medicare, you generally cannot use your HSA to reimburse their Medicare premiums tax-free.5Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans
A Spouse’s IRMAA on a Joint Return
Joint filers combine all medical expenses either spouse paid during the year into a single pool for the 7.5% calculation, and that pool includes both spouses’ Medicare premiums and IRMAA.6Internal Revenue Service. Publication 502 – Medical and Dental Expenses Two people’s costs measured against one threshold improves the odds of clearing it.
If you file separately, the rules tighten. In a non-community-property state, each spouse can only deduct what they personally paid; joint-account payments are generally treated as split equally. In a community property state, medical expenses paid from community funds are divided equally between the spouses’ separate returns.6Internal Revenue Service. Publication 502 – Medical and Dental Expenses Filing separately also triggers the harshest IRMAA brackets: married-separate filers who lived together at any point in the year skip the middle tiers, so income above $109,000 jumps to the second-highest Part B premium.7Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles Higher surcharges and split deductions make that filing status expensive on both ends.
If the Deduction Won’t Help, Consider an Appeal
IRMAA runs on your MAGI from two years earlier. For 2026 premiums, Social Security uses your 2024 tax return, or 2023 if 2024 isn’t available.8Social Security Administration. Premiums: Rules for Higher-Income Beneficiaries If your income has dropped since then, filing Form SSA-44 asks SSA to use a more recent or estimated figure.9Social Security Administration. Form SSA-44 – Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event
SSA will only reconsider if the drop resulted from one of these recognized life-changing events:
- Marriage, divorce, or death of a spouse
- Work stoppage or reduction in hours
- Involuntary loss of income-producing property from disaster, fraud, or similar circumstances
- Loss of pension income
- Employer settlement payment following employer closure or bankruptcy
Retirement itself typically qualifies under work stoppage, which makes the appeal especially relevant in the first years after leaving a high-paying job. You can also request a new determination if SSA used outdated or incorrect tax data, such as when an amended return shows lower income.
Lowering Future IRMAA Beats Deducting It
Because IRMAA runs on your MAGI from two years back, the most effective response is controlling what shows up in that figure. Proactive planning outperforms a limited itemized deduction almost every time.
Qualified Charitable Distributions
If you’re 70½ or older and giving to charity from an IRA, a qualified charitable distribution keeps the donated amount out of your AGI entirely. A regular IRA withdrawal followed by a personal donation adds the full withdrawal to your income even after the charitable deduction offsets it. A QCD sends the money straight from IRA to charity, and it never lands on your return as income. Only the QCD version lowers the MAGI that SSA uses to set IRMAA.
Roth Conversion Timing
Roth conversions raise your MAGI in the year of the conversion, and that spike shows up in your IRMAA calculation two years later. A large conversion right before Medicare enrollment, or in any year after, can trigger significant surcharges down the road. Spreading conversions across multiple years keeps each year’s MAGI lower. Front-loading them before age 63 avoids the IRMAA impact for those converted amounts altogether.
Capital Gains Management
Realized capital gains flow into your AGI, and one big sale can push you across a bracket line two years later. Spreading sales across tax years or harvesting losses to offset gains helps hold MAGI below the next threshold. Bracket boundaries matter here: a joint filer near $218,000 in MAGI who tips over on a few thousand dollars of extra gains triggers an $81.20 monthly Part B surcharge plus a $14.50 Part D surcharge, roughly $1,148 in additional Medicare costs per person for the year.7Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
None of this eliminates IRMAA for anyone with genuinely high ongoing income. But for retirees with some control over the timing and character of income, staying just under a bracket threshold saves more than any deduction can recover.
