Medical expenses can be substantial, and many taxpayers wonder whether those costs provide any tax relief.
For the 2025 tax year, qualifying medical expenses may be deductible on Schedule A if you itemize your deductions and your total qualifying medical expenses exceed 7.5 percent of your adjusted gross income (AGI).
This threshold means that for most Americans with modest medical costs, the deduction provides no benefit—and even for those with significant expenses, only the amount above the 7.5 percent floor is deductible.
The IRS defines qualifying medical expenses broadly in Publication 502, covering a wide range of treatments, prescriptions, dental and vision care, and certain equipment.
Non-qualifying expenses include cosmetic procedures, gym memberships tax deductible rules are strict—most fitness costs don't qualify—and most vitamins.
Understanding exactly what counts—and how to calculate and claim the deduction—can help taxpayers with high medical costs maximize their tax benefit.
Are Medical Expenses Tax Deductible? The Short Answer
Yes, qualifying medical expenses are deductible—but with important conditions that make the deduction unavailable to most taxpayers:
- You must itemize deductions. The medical expense deduction is only available on Schedule A. If your total itemized deductions do not exceed the standard deduction for your filing status ($15,000 single / $30,000 MFJ / $22,500 HOH for the 2025 tax year), itemizing provides no tax benefit.
- Only expenses above 7.5% of AGI are deductible. If your AGI is $80,000, only qualifying medical expenses exceeding $6,000 (7.5% × $80,000) are deductible. The first $6,000 provides no deduction benefit.
- Expenses must be paid with after-tax dollars. Amounts reimbursed by insurance, paid from an FSA or HSA, or otherwise covered by another source cannot be deducted.
- The expenses must be for 'medical care' as defined by the IRS. IRS Publication 502 defines medical care as amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body.[1]
IRS Requirements and Rules
The IRS establishes specific requirements that determine whether a medical expense is deductible and the amount that qualifies.
The 7.5% AGI Threshold
For the 2025 tax year, taxpayers may deduct only the portion of qualifying medical expenses that exceeds 7.5 percent of their adjusted gross income.
This threshold has been 7.5% since the Tax Cuts and Jobs Act of 2017 permanently established it.
The threshold applies to gross qualifying expenses before insurance reimbursements—you subtract reimbursements to arrive at net qualifying expenses, then apply the 7.5% calculation.
Taxpayers who also pay health insurance premiums tax deductible with after-tax dollars can include those premiums in the total qualifying expense calculation.
Who Qualifies as a Medical Care Recipient
You may deduct qualifying medical expenses paid for yourself, your spouse, and your dependents—including children up to age 26 for health insurance purposes, though tax dependency rules may differ.
You may also be able to deduct expenses for a person who would qualify as your dependent except that they earned too much income or file jointly.
Timing: Year Paid Matters
Medical expenses are deductible in the year you pay them, not the year the service is provided.
If you received treatment in December 2024 but paid the bill in January 2025, the expense is deductible in your 2025 return (filed in 2026).
Planning large medical expenses to fall in a single tax year may allow you to maximize the deduction by exceeding the 7.5% threshold in that year.
Insurance Reimbursements
Only the net unreimbursed portion of medical expenses qualifies.
If your insurance reimbursed $2,000 of a $3,000 bill, only $1,000 is a qualifying expense.
If you were reimbursed in a later year for expenses you previously deducted, you may need to report the reimbursement as income in the year received.
Standard Deduction vs. Itemizing
For the 2025 tax year, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for heads of household.
To benefit from medical expense deductions, your total itemized deductions must exceed the standard deduction for your filing status.
Deductible interest on a home loan—such as the mortgage interest deduction—can combine with medical expenses to help you clear that threshold.
When Medical Expense Deductions Are Worth Itemizing
The combination of the high standard deduction and the 7.5% AGI floor means that itemizing for medical expenses makes sense primarily when you have: (1) very high unreimbursed medical costs in a single year, and (2) other itemized deductions (mortgage interest, state and local taxes, charitable contributions) that together with excess medical costs exceed the standard deduction.
For example, a single filer with $60,000 AGI, $8,000 in unreimbursed medical expenses, and $10,000 in other deductions would have itemized deductions of $13,500 ([$8,000 – $4,500] + $10,000), which is less than the $15,000 standard deduction.
Bunching Medical Expenses
If you have flexibility in timing elective procedures, dental work, or other medical expenses, concentrating deductible medical expenses into a single tax year may allow you to exceed both the 7.5% threshold and the standard deduction, making itemizing advantageous in that year while taking the standard deduction in other years.
This strategy works particularly well when combined with dental insurance tax deductible costs in the same calendar year.
What Qualifies and What Doesn't
IRS Publication 502 provides the definitive list of qualifying and non-qualifying medical expenses. Here is a practical summary.
Qualifying Medical Expenses
Qualifying expenses generally include: doctor, dentist, and specialist office visits and fees.
Hospital and surgery costs.
Prescription medications.
Vision care (eyeglasses, contact lenses, LASIK).
Hearing aids and batteries.
Dental treatment (fillings, extractions, dentures, orthodontia for medical necessity).
Mental health treatment (psychiatrists, psychologists, therapy).
Physical therapy and occupational therapy.
Chiropractic care.
Laboratory fees and diagnostic testing.
Medical equipment (crutches, wheelchairs, insulin pumps).
Nursing home care for medical reasons.
Transportation costs to obtain medical care.
And health insurance premiums paid with after-tax dollars (subject to the 7.5% threshold for employees).[1].
Non-Qualifying Medical Expenses
Non-qualifying expenses include: cosmetic surgery or procedures that are not medically necessary (elective rhinoplasty, teeth whitening, face lifts).
whether a gym membership is tax deductible—generally it is not, even if recommended by a doctor.
Weight-loss programs not for a specific disease.
Vitamins, supplements, and herbal remedies (unless prescribed for a specific diagnosed condition).
Maternity clothes.
funeral expenses tax deductible—funeral costs are not a qualifying medical expense.
And any expense reimbursed by insurance or paid with FSA/HSA funds.
Borderline Categories
Some expenses may qualify in certain circumstances but not others. Long-term care services qualify if the patient meets IRS criteria for chronic illness. Weight-loss programs may qualify if prescribed by a physician for a specific diagnosed disease such as obesity or hypertension.
Cosmetic surgery may qualify if required to correct a deformity arising from a congenital abnormality, accident, or disease. Always consult IRS Publication 502 or a tax professional for borderline situations.
How to Claim the Deduction
Claiming the medical expense deduction requires completing Schedule A and meeting the itemization threshold.
Schedule A, Form 1040
Medical expenses are reported on Schedule A (Itemized Deductions), Lines 1 through 4. Line 1: enter total qualifying medical and dental expenses paid during the year. Line 2: enter your AGI (from Form 1040, Line 11).
Line 3: multiply Line 2 by 7.5% (0.075). Line 4: subtract Line 3 from Line 1—if positive, this is your allowable deduction. Transfer Line 4 to your total itemized deductions and compare to the standard deduction for your filing status.[3]
Record-Keeping Requirements
Maintain detailed records of all medical expenses claimed, including: receipts and invoices from medical providers, pharmacy receipts for prescription medications, insurance Explanation of Benefits (EOB) statements showing your out-of-pocket payments, and documentation that expenses were not reimbursed.
The IRS recommends keeping tax records for at least 3 years from the filing date.
In cases of substantial underpayment of tax, the IRS may audit returns up to 6 years back.
Using IRS Tools to Determine Eligibility
The IRS Interactive Tax Assistant tool at IRS.gov can help taxpayers determine whether a specific medical expense qualifies as a deduction.
The tool asks a series of questions and provides guidance based on current tax law.
IRS Publication 502 remains the most comprehensive resource for medical expense deduction eligibility.[2]
Frequently Asked Questions
What is the medical expense deduction threshold for 2025?
For the 2025 tax year, qualifying medical expenses are deductible on Schedule A only to the extent they exceed 7.5 percent of your adjusted gross income (AGI).
For example, if your AGI is $70,000, only qualifying medical expenses above $5,250 are deductible.
You must also itemize your deductions rather than take the standard deduction.
Can I deduct prescription medication costs?
Yes, prescription medications purchased in the United States are a qualifying medical expense under IRS Publication 502.
Over-the-counter medications do not qualify unless prescribed by a doctor (which is not possible in most states for standard OTC items).
Insulin qualifies as a deductible medical expense regardless of whether it requires a prescription.
Can I deduct medical expenses paid for a family member?
You may deduct qualifying medical expenses paid for yourself, your spouse, and individuals who qualify as your dependents for federal tax purposes.
You may also deduct expenses paid for someone who would qualify as a dependent except that they had too much gross income or file a joint return.
The expenses must be paid in the tax year for which you claim the deduction.
If your family also incurs significant child care tax deductible expenses, those are governed by a separate credit and cannot be double-counted here.
Are dental and vision expenses tax deductible?
Yes. Dental expenses including checkups, cleanings, fillings, extractions, orthodontia (for medical necessity), and dentures are qualifying medical expenses. Vision expenses including eyeglasses, contact lenses, eye exams, and LASIK surgery to correct vision also qualify.
These are subject to the same 7.5% AGI threshold and itemization requirement as all other medical expenses. If you pay dental insurance tax deductible premiums out of pocket, those also count toward your total qualifying expenses.
Can I deduct medical expenses paid with an HSA or FSA?
No. Expenses paid with funds from a Health Savings Account (HSA) or Flexible Spending Account (FSA) are excluded from taxable income through those programs and cannot be deducted again on Schedule A.
Deducting the same expense twice is a form of double-dipping that is not permitted.
You may only deduct unreimbursed medical expenses—those paid entirely with after-tax, out-of-pocket dollars.
For context, similar rules apply to health insurance premiums tax deductible under the self-employed deduction—you can't deduct amounts already excluded from income.
