Medicare Supplement premiums are not tax deductible for most people
If you pay for a Medigap policy (the formal name for Medicare Supplement insurance), you cannot deduct those premiums on your federal income tax return. The IRS treats Medigap premiums the same way it treats most health insurance you buy yourself — as a personal expense, not a business or medical deduction.
The one exception is narrow: if you are self-employed and pay for Medigap as part of a health insurance plan you set up for yourself, you may be able to deduct it as a self-employed health insurance deduction. This applies only if you have net self-employment income and meet specific IRS rules. Most people on Medicare are retired and do not have self-employment income, so this exception rarely applies.
The rules are different for long-term care insurance and Medicare Advantage premiums, which have their own tax treatment. Understanding which type of coverage you have matters because the tax rules diverge sharply.
Key Takeaways
- Medigap (Medicare Supplement) premiums paid with after-tax dollars cannot be deducted on your federal tax return.
- If you are self-employed with net self-employment income, you may deduct Medigap premiums as a self-employed health insurance deduction, but this is rare for Medicare beneficiaries.
- Long-term care insurance premiums have different rules and may be partially deductible as a medical expense if your total medical costs exceed a threshold.
- Medicare Advantage premiums also cannot be deducted, though some out-of-pocket costs may count toward medical deductions if they exceed the IRS floor.
Why Medigap premiums do not may have access to as a deduction
The IRS distinguishes between health insurance premiums you pay yourself and those paid by an employer or a government program. Medigap is supplemental insurance you buy on the private market to cover costs Medicare does not pay — copayments, coinsurance, and deductibles. Because you purchase it as an individual consumer, not through an employer or as a business expense, it falls into the category of personal health care costs.
Personal health care costs are generally not deductible. You can only deduct medical expenses — which include doctor visits, hospital stays, prescription drugs, and some medical equipment — if they exceed 7.5% of your adjusted gross income (AGI) in a tax year. Even then, you can only deduct the amount above that threshold. Medigap premiums do not count toward that threshold.
This is a common source of confusion because people assume that any health insurance premium should be deductible. In reality, the IRS treats Medigap the way it treats any other insurance you buy for yourself: as a personal expense that comes out of your after-tax income.
The self-employed exception and who it actually applies to
If you are self-employed and have net self-employment income, you can deduct health insurance premiums — including Medigap — as a business expense on your tax return. This deduction is called the self-employed health insurance deduction, and it appears on Form 1040, not on Schedule C.
To use this deduction, you must meet three conditions: you must be self-employed with net profit from your business, you cannot be covered by an employer health plan (either your own business's plan or a spouse's employer plan), and you must have enough net self-employment income to cover the deduction. The deduction cannot exceed your net self-employment income for the year.
For most people on Medicare, this exception does not explore. If you are retired and have no self-employment income, you cannot use this deduction. If you are still working part-time as a consultant or freelancer and have net self-employment income, you may be able to deduct Medigap premiums, but you will need to document your business income and consult a tax professional to may support you meet the IRS requirements.
Long-term care insurance has different tax rules
Long-term care insurance (coverage for nursing home care, assisted living, or in-home care) is treated differently from Medigap. A portion of your long-term care insurance premiums may be deductible as a medical expense if your total medical expenses exceed 7.5% of your AGI.
The deductible amount depends on your age. The IRS sets an annual limit on how much of your long-term care premium counts as a deductible medical expense. For 2024, those limits range from $430 per year for people under 40 to $5,430 per year for people over 76. If your premium is higher than the limit for your age, only the amount up to the limit counts as a medical expense.
To claim this deduction, your total medical expenses for the year (including the deductible portion of long-term care premiums, doctor visits, prescriptions, and other may have access to medical costs) must exceed 7.5% of your AGI. You then deduct only the amount above that threshold. This is a much narrower path than many people expect.
Medicare Advantage premiums and tax deductions
Medicare Advantage (Part C) plans are an alternative to Original Medicare plus Medigap. Many Advantage plans have a $0 premium, though some charge a monthly fee. If your plan does charge a premium, that premium is not deductible for the same reason Medigap premiums are not: it is a personal health insurance expense.
However, if you have an Advantage plan and pay out-of-pocket costs (copayments, coinsurance, deductibles) that exceed 7.5% of your AGI when combined with other medical expenses, you can deduct the amount above that threshold. This is different from deducting the premium itself — you are deducting the actual medical costs the plan does not cover.
What you should do if you pay Medigap premiums
Keep records of what you pay for Medigap each month or year. Even though you cannot deduct the premiums themselves, you may need documentation if you are audited or if you are trying to determine whether you may have access to for other information programs that count health insurance costs as part of your expenses.
If you are self-employed, consult a tax professional before claiming a deduction for Medigap premiums. The rules are specific, and mistakes can trigger an audit. A tax preparer can review your business income, your coverage situation, and your other health expenses to determine what you can actually deduct.
If your total medical expenses (including doctor visits, prescriptions, hospital costs, and any deductible long-term care premiums) exceed 7.5% of your AGI, you may still benefit from itemizing deductions on your tax return. Medigap premiums themselves will not be part of that calculation, but other medical costs will be.
Frequently Asked Questions
Can I deduct Medigap premiums if I pay them from a Health Savings Account?
No. You cannot use a Health Savings Account (HSA) to pay Medigap premiums, even though you can use an HSA for other medical expenses. Once you enroll in Medicare, you are no longer may be able to access to contribute to an HSA. If you already have an HSA, you can withdraw money to pay for Medicare premiums (Part B, Part D, and Advantage), but not Medigap.
What if my employer pays part of my Medigap premium?
If your former employer or a current employer subsidizes your Medigap premium as a retiree benefit, that employer-paid portion is not taxable income to you, and you do not deduct it. You only pay tax on the portion you pay yourself, and that portion is still not deductible.
Do state taxes treat Medigap premiums differently than federal taxes?
Most states follow the federal rule and do not allow a deduction for Medigap premiums. A few states have different rules for medical expenses or long-term care insurance, so check your state's tax guidance or speak with a state tax professional if you live in a state with its own income tax.
If I cannot deduct Medigap premiums, can I deduct the copayments and deductibles it covers?
No. Medigap is designed to cover copayments and deductibles, so those costs are paid by the insurance, not by you directly. You can only deduct medical expenses you pay out of your own pocket. Costs covered by insurance do not count.
What records do I need to keep for Medigap premiums if I cannot deduct them?
Keep your monthly or annual premium statements and payment records. You may need them to verify your health insurance coverage for other purposes, such as determining whether you owe a penalty for not having coverage (though Medicare beneficiaries are exempt) or for calculating costs if you move to a different state or plan.
