Yes, But Most People Won’t See a Dime Back
Medicare supplement premiums are tax deductible — technically. The IRS counts them as a medical expense, which means they can reduce your taxable income. But here’s the thing: the rules around medical expense deductions are strict enough that the majority of retirees never actually get a benefit from this. I don’t want you to spend the next hour organizing receipts based on a half-true answer you read somewhere else.
Let me walk you through exactly how it works, who it actually helps, and what most people get wrong about it.
How the Medical Expense Deduction Actually Works
The IRS allows you to deduct medical expenses — including Medigap premiums — under Schedule A of your federal tax return. But there’s a catch that eliminates most people before they even get started: you can only deduct the portion of your total medical expenses that exceeds 7.5% of your adjusted gross income (AGI).
So if your AGI is $50,000, your medical expenses need to top $3,750 before you can deduct even a single dollar. And you only get to deduct what’s above that threshold, not the whole amount.
Here’s a real example. Say you’re a 67-year-old in Ohio paying $145 a month for Plan G. That’s $1,740 a year in Medigap premiums. Add your Part B premium (the standard 2026 rate is $185 a month, so $2,220 a year), and you’re at $3,960 in combined premiums alone. On a $50,000 AGI, your threshold is $3,750, so you’d be looking at a deductible amount of about $210. That’s not nothing, but it’s unlikely to make a meaningful difference in your tax bill.
Now add out-of-pocket costs — dental work, hearing aids, prescription drugs, medical travel — and the picture can shift. For people with significant health expenses in a given year, this deduction becomes genuinely useful. But for someone who’s relatively healthy and has a modest income, it probably won’t move the needle.
There’s also the standard deduction to consider. In 2026, the standard deduction for a single filer aged 65 or older is $16,550, and for a married couple both 65 or older, it’s around $30,600. If your itemized deductions — including that medical expense figure — don’t beat the standard deduction, you’re taking the standard deduction anyway, and your Medigap premiums are effectively not helping you at all.
What Counts (and What Doesn’t)
If you do decide to itemize, it helps to know what you can bundle into that medical expense total. The IRS is broader than most people expect here.
Eligible medical expenses you can add to your Medigap premiums include:
- Medicare Part B premiums
- Medicare Part D premiums
- Medicare Advantage premiums (if applicable)
- Long-term care insurance premiums (up to age-based limits)
- Dental and vision care costs
- Prescription drug costs not covered by insurance
- Medical equipment like wheelchairs or hearing aids
- Mileage driven to medical appointments (the 2026 medical mileage rate is 21 cents per mile)
- Amounts paid to doctors, hospitals, and specialists after insurance pays its share
What doesn’t count: gym memberships (even if your doctor recommended exercise), cosmetic procedures, over-the-counter medications in most cases, and health expenses that were reimbursed by insurance.
The bundling matters. If you had a significant health event in 2026 — a hospitalization, major surgery, expensive dental work — you might find that your total medical expenses clear that 7.5% threshold by a wide margin. In those situations, tracking every deductible expense including your Medigap premiums is worth doing.
The Mistake I See People Make All the Time
I’ve talked to a lot of Medicare beneficiaries who believe they’re deducting their Medigap premiums when they’re actually not. Here’s how it happens.
They hear that Medigap premiums are tax deductible, so they list them on their taxes. Their tax software or their accountant dutifully notes the amount. But because their total itemized deductions don’t exceed the standard deduction, the software automatically selects the standard deduction. The Medigap premiums never actually reduced their tax bill. They got no benefit from the deduction at all.
This isn’t a mistake that costs you money in extra taxes — you’re not doing anything wrong. But it can create a false sense of confidence. People think they’re getting a tax break on their Medicare supplement, when really they just did extra paperwork for nothing.
The only way this deduction genuinely helps you is if you’re itemizing, and your itemized total beats your standard deduction. If you’re not sure which applies to you, a tax professional can tell you in about five minutes.
There’s a related misconception worth clearing up: some people think they can deduct Medigap premiums directly from their Social Security income, reducing it dollar for dollar. That’s not how it works. Social Security isn’t reduced by medical expenses — Part B premiums are deducted automatically from Social Security payments, but that’s just how the billing works, not a tax deduction.
Who Actually Benefits From This Deduction
In my experience, two groups of people tend to get real value from deducting Medicare supplement premiums.
The first group is people with higher-than-average medical costs in a given year. If you had a hip replacement, significant dental reconstruction, or started paying for hearing aids in 2026, your medical expenses might already be well above that 7.5% AGI threshold. At that point, adding your Medigap premiums to the pile makes the deduction larger and your tax bill smaller.
The second group is people with relatively lower incomes. The 7.5% threshold is based on your AGI, so someone with an AGI of $25,000 only needs $1,875 in medical expenses before the deduction kicks in. On that income, $1,740 in Medigap premiums plus their Part B premium gets them past the threshold quickly. Combined with other medical costs, the deduction can be meaningful.
Here’s a comparison that makes this clearer:
| Scenario | AGI | 7.5% Threshold | Total Medical Expenses | Deductible Amount |
|---|---|---|---|---|
| Healthy retiree, average income | $55,000 | $4,125 | $3,960 | $0 |
| Retiree with major surgery | $55,000 | $4,125 | $11,500 | $7,375 |
| Lower-income retiree | $24,000 | $1,800 | $4,200 | $2,400 |
| Higher-income retiree | $90,000 | $6,750 | $4,200 | $0 |
The numbers in the table are estimates using typical 2026 premium figures. Your actual situation depends on your specific expenses and income.
One more group worth mentioning: self-employed people who are on Medicare. If you’re still running a business and paying for your own health insurance, different rules may apply. Self-employed individuals can sometimes deduct 100% of health insurance premiums above the line — meaning you don’t have to itemize. Talk to a tax professional if this is your situation, because it changes things considerably.
Bottom Line
For most retirees, the Medicare supplement premium deduction sounds better than it actually is. If you’re taking the standard deduction — and most people over 65 are — this deduction isn’t doing anything for you, regardless of how much you paid in Medigap premiums. That said, if you had significant medical expenses in a given year, or if your income is lower, it’s absolutely worth tracking every dollar and running the numbers with a tax pro before you file.
Frequently Asked Questions
Can I deduct my Medicare supplement premium if I don’t itemize?
No. The medical expense deduction only applies when you itemize on Schedule A. If you take the standard deduction — which most people over 65 do — you can’t separately deduct your Medigap premiums. There’s no above-the-line deduction available for Medigap premiums unless you’re self-employed, in which case different rules may apply.
Do Medicare Advantage premiums get the same tax treatment as Medigap premiums?
Yes, they’re treated the same way by the IRS. Both are considered medical insurance premiums and qualify as medical expenses under Schedule A. The same 7.5% AGI threshold applies, and the same standard deduction issue applies. The type of supplement coverage you have doesn’t change the basic rules.
Are Medigap premiums deductible in all states?
At the federal level, the rules are the same everywhere. Some states have their own income tax rules that may be more generous — a handful of states allow medical expense deductions at a lower threshold than 7.5%, and a few states have no income tax at all. It’s worth checking your state’s specific rules, especially if you live somewhere like Arizona, Colorado, or Montana that has its own medical deduction structure.
What if my spouse and I both have Medigap policies — can we deduct both premiums?
Yes, you can combine both sets of premiums when calculating your total medical expenses on a joint return. If you’re both paying $145 to $175 a month for your respective Plan G policies, that’s $3,480 to $4,200 a year combined just from Medigap, before you add Part B premiums, Part D costs, and any out-of-pocket expenses. On a joint return with the higher married standard deduction, you’ll still need your total itemized deductions to beat roughly $30,600 in 2026 to get any benefit from itemizing at all.
