Key Facts
- Itemized deduction: Eligible unreimbursed health-insurance premiums can count as medical expenses, but only the total qualifying medical expenses above 7.5% of adjusted gross income is deductible on Schedule A.
- Itemizing required: The Schedule A route provides no additional federal deduction when the standard deduction is claimed.
- No double benefit: Premiums paid pretax through an employer plan, reimbursed premiums, and amounts covered by the premium tax credit generally cannot also be deducted as medical expenses.
- Self-employed route: An eligible self-employed person may claim an adjustment to income for qualifying premiums, subject to earned-income and employer-plan eligibility limits.
- Medicare: Medicare Part B and Part D premiums generally can qualify as medical expenses; Part A depends on how coverage was obtained and paid.
Health insurance premiums can be tax deductible under federal law, but the answer depends on who paid them, whether the payment was pretax or after-tax, whether anyone reimbursed it, and which deduction route applies. Employees and other individuals usually consider the Schedule A medical-expense deduction, while eligible self-employed people may have a separate adjustment to income.
The same premium cannot create two federal tax benefits. Records must separate the taxpayer’s after-tax cost from employer payments, premium tax credits, reimbursements, health-account distributions, and other amounts already excluded from income.
Schedule A: the itemized medical-expense route
Health-insurance premiums paid for medical care can be included with other qualifying medical and dental expenses. The deduction is not the full premium amount. For 2025 returns, Schedule A allows only the total eligible expenses above 7.5% of adjusted gross income.
Suppose adjusted gross income is $80,000 and eligible unreimbursed medical expenses, including after-tax premiums, total $9,000. The 7.5% threshold is $6,000, leaving $3,000 for the medical-expense line. That amount joins the taxpayer’s other itemized deductions; it does not automatically reduce tax by $3,000.
The taxpayer must itemize for this route to matter. If the standard deduction produces the better result, listing eligible premiums does not create an additional deduction outside Schedule A. The broader tax deductions guide explains the distinction between itemized deductions and adjustments to income.
Whose premiums can be included?
Publication 502 generally permits qualifying medical expenses paid for the taxpayer, spouse, and dependents, with detailed rules for dependency status, children of divorced or separated parents, and other situations. Eligibility is tested under the medical-expense rules rather than simply by whose name appears on the policy.
Medical insurance can include policies covering hospital and medical care, prescription drugs, dental care, vision care, and qualified long-term care, subject to the specific limits and exclusions. Premiums for a policy that pays a fixed amount for lost earnings or other nonmedical benefits do not qualify merely because illness triggers payment.
Employer coverage and pretax payroll deductions
An employee cannot deduct the portion of a premium treated as paid by the employer. Premiums paid through a cafeteria plan or premium-conversion arrangement generally use pretax compensation and are not deductible again unless the amount was included in taxable wages, such as box 1 of Form W-2.
Pay-stub terminology can be misleading. “Employee contribution” does not necessarily mean after-tax payment. Payroll records should show whether the deduction reduced federal taxable wages.
COBRA premiums paid personally with after-tax funds can generally enter the Schedule A medical-expense calculation. The same 7.5% threshold, reimbursement limits, and itemizing requirement still apply.
The self-employed health-insurance deduction
A qualifying self-employed person may deduct health-insurance costs as an adjustment to income rather than an itemized deduction. IRS guidance includes a sole proprietor with net profit, a partner with net self-employment earnings, and a more-than-2% S corporation shareholder receiving wages when the applicable requirements are satisfied.
The deduction can cover qualifying medical and dental insurance and qualified long-term-care insurance for the taxpayer, spouse, dependents, and a child who was under age 27 at year-end even if the child was not a dependent. Form 7206 is used to calculate the allowable self-employed health-insurance deduction when required.
The deduction cannot exceed the earned income from the trade or business under which the insurance plan is established. It is also generally unavailable for any month the taxpayer was eligible to participate in a subsidized health plan maintained by the taxpayer’s employer or a spouse’s employer, even if enrollment was declined.
Any eligible premium not allowed under the self-employed calculation may still be considered with other medical expenses on Schedule A if the itemized-deduction rules are met. It cannot be deducted twice.
Marketplace coverage and the premium tax credit
Marketplace coverage requires separating the full premium from the taxpayer’s actual cost and any premium tax credit. Publication 502 does not allow the portion of a premium paid by the credit to be included as a medical expense.
Advance credit payments are reconciled on Form 8962. A repayment of excess advance credit or an additional credit allowed on the return can change the amount treated as paid for insurance, and Publication 974 contains special iterative calculations when a self-employed health-insurance deduction and premium tax credit interact.
Using the gross premium from Form 1095-A without completing the credit reconciliation can therefore overstate the deduction. Preserve Form 1095-A, Form 8962, marketplace statements, and proof of the amounts actually paid.
Medicare premiums
Medicare Part B premiums generally qualify as medical expenses, as do Medicare Part D premiums. Medicare Advantage premiums can also qualify to the extent they pay for medical-care insurance.
Medicare Part A requires a distinction. Someone covered under Social Security or who paid Medicare tax ordinarily cannot include Part A as a medical expense. A person who was not covered and voluntarily enrolled may include premiums actually paid, subject to the other deduction requirements.
Premiums withheld from Social Security benefits are still amounts paid by the beneficiary for purposes of assembling records. The deduction result still depends on whether the coverage qualifies, whether expenses exceed the AGI floor, and whether the taxpayer itemizes or qualifies for the self-employed route.
Long-term-care insurance limits
Premiums for a qualified long-term-care insurance contract can be medical expenses, but the includible amount is capped by an age-based annual limit. The limits change with the tax year, so the current Publication 502 table must be used.
Qualified long-term-care premiums are also subject to the Schedule A threshold or the separate self-employed calculation, as applicable. A policy marketed as long-term care is not enough; it must meet the federal definition of a qualified contract.
Reimbursements and health accounts
Only unreimbursed expenses belong in the medical-expense calculation. Insurance reimbursements, employer reimbursements, and tax-free health reimbursement arrangement payments reduce the amount that can be included.
An expense paid with a tax-free distribution from a health savings account or other tax-favored medical account cannot also be claimed as an itemized medical deduction. If a reimbursement arrives after a deduction produced a tax benefit, recovery rules may require income in the later year.
Records that support the deduction
Useful records include policy statements, invoices, bank or credit-card proof, pay stubs showing pretax or after-tax treatment, Forms W-2 and 1095-A, Form 8962, reimbursement statements, and Medicare benefit statements. Keep calculations showing which months and people were covered.
Use records for the tax year in which the expense was paid. A billed amount, an insurer’s allowed amount, and the amount actually paid are different figures. Reconcile them before applying either deduction route.
This guide addresses the federal income-tax treatment of premiums. State deductions and income definitions can differ and must be checked under the relevant state’s current instructions.
