Quick overview

Nonreimbursed medical expenses are the medical and dental costs you pay yourself — not paid or reimbursed by an insurer or another payer — that may be deductible when you itemize on Schedule A (Form 1040). The IRS allows a deduction only for the portion of those expenses that exceeds 7.5% of your adjusted gross income (AGI) for tax years through 2025 (IRS Publication 502). The practical result: unless you have unusually high out-of-pocket costs, the standard deduction will often be larger than your itemized total.

Below I explain which expenses usually qualify, how to calculate the deductible amount, timing and recordkeeping strategies I use with clients, common pitfalls, and links to related FinHelp guides to help you act confidently during tax-year planning.

What counts — common qualifying and nonqualifying expenses

The IRS lists dozens of allowable medical and dental expenses in Publication 502. Typical qualifying unreimbursed expenses include:

  • Payments to doctors, dentists, surgeons, chiropractors, and psychiatrists.
  • Prescription medications and insulin (note: most over-the-counter drugs are not deductible unless prescribed).
  • Hospital services, lab tests, and X-rays.
  • Medical equipment and supplies (e.g., crutches, wheelchairs, prosthetics, hearing aids).
  • Long-term care services and some long-term care insurance premiums (subject to limits/age-based rules).
  • Transportation and lodging costs primarily for and essential to medical care (keep detailed logs and receipts).
  • Certain home modifications for medical reasons (ramps, widened doorways) when primarily for medical care.

Expenses that generally do not qualify: cosmetic surgery for purely aesthetic reasons, nonprescription drugs (except insulin), general health club dues, and most life insurance premiums.

Note: Employer-paid health premiums, HSA distributions used for qualified medical expenses, Medicare premiums, and some other items have special treatment. For example, self-employed taxpayers may be able to deduct health insurance premiums above the line (see IRS instructions), while other taxpayers include those premiums as part of medical expenses on Schedule A.

(See IRS Pub 502 for the full list and definitions.)

Who benefits and the 7.5% AGI threshold

To claim medical expense deductions you must itemize deductions on Schedule A. The deductible portion equals your total qualifying unreimbursed medical expenses minus 7.5% of your AGI. Example math:

  • AGI = $60,000
  • Total unreimbursed medical expenses = $7,500
  • 7.5% of AGI = $4,500
  • Deductible medical expenses = $7,500 − $4,500 = $3,000

If the resulting deductible total plus your other itemized deductions (mortgage interest, state and local taxes, charitable gifts) exceeds the standard deduction for your filing status, you’ll likely benefit from itemizing. Otherwise, you’ll take the standard deduction.

Practical tax-year strategies I use with clients

  1. Bunch elective but necessary medical procedures into a single calendar year. If you’re close to the 7.5% AGI floor, scheduling non-urgent but medically necessary care (e.g., dental work, cataract surgery) within the same tax year can push you over the threshold.

  2. Prepay medical bills when appropriate. Paying a medical bill before year-end (if the provider accepts early payment) can increase deductible expenses in that tax year. Don’t prepay purely to manipulate deductions without real medical need.

  3. Maximize tax-advantaged accounts first. Use Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) for eligible expenses. HSAs provide triple tax benefits (pre-tax contributions, tax-free growth, and tax-free distributions for qualified medical costs). Contribution limits change annually — see IRS Publication 969 for current HSA limits.

  4. Track transportation and lodging related to care. Mileage to and from medical appointments (when using your own car) can be deductible at the IRS medical mileage rate; rideshare/taxi receipts and lodging costs while receiving distant treatment can also qualify when documented.

  5. Combine family expenses on one return. If you’re married and filing jointly, combine both spouses’ expenses to meet the AGI threshold. If filing separately, each spouse’s expenses are compared to their own AGI.

  6. Use documentation-friendly payments. Use credit cards, bank transfers, or checks that create a paper trail — essential if the IRS questions a deduction. Keep explanation-of-benefit (EOB) statements and receipts.

In my practice as a CPA and financial planner, I’ve helped clients increase their itemizable totals with careful timing and by ensuring all eligible categories (including travel and equipment) were included. One client moved a $2,500 dental procedure into the same year as ongoing therapy and crossed the 7.5% threshold, unlocking a deductible amount that produced a meaningful tax refund.

Recordkeeping checklist (what to keep and for how long)

  • Receipts, invoices, and paid statements from medical providers.
  • Prescription receipts and pharmacy logs.
  • Health insurer Explanation of Benefits (EOBs) showing amounts billed, paid, and denied.
  • Bank or credit card statements showing payments.
  • Mileage logs showing dates, miles, purpose, and locations for medical travel.
  • Documentation for home improvements (invoices + a doctor’s letter if required).

Keep records for at least three years from the date you file, but consider seven years for added safety if you claim large deductions or if your return shows a net operating loss.

Common mistakes and how to avoid them

  • Not itemizing when you should: run the numbers before you choose standard vs itemized. Use a worksheet or tax software to compare.
  • Forgetting reimbursements: any amount reimbursed by insurance or a third party reduces the deductible expense.
  • Misclassifying expenses: label lodging or transportation incorrectly; keep a clear log explaining why a trip or modification was medical in nature.
  • Overlooking small, cumulative costs: co-pays, over-the-counter supplies (only when prescribed), and necessary medical supplies add up and should be tracked.

Interaction with other tax items (HSAs, FSAs, COBRA, self-employed premiums)

  • HSA/FSA: Qualified expenses paid with HSA/FSA dollars are not deductible again on Schedule A. However, when you exhaust HSA/FSA funds, subsequent out-of-pocket costs remain eligible for Schedule A if unreimbursed.
  • Self-employed health insurance: Self-employed taxpayers may deduct health insurance premiums as an adjustment to income (above-the-line), which reduces AGI and indirectly lowers the 7.5% AGI floor — this is often more valuable than counting those premiums on Schedule A.
  • COBRA premiums and Medicare premiums: Generally deductible as medical expenses on Schedule A when unreimbursed, but check specific rules and reporting.

Always verify account limits and reporting rules with the current year’s IRS guidance (Pub 969 for HSAs; 1040 instructions for self-employed health insurance).

Real-world examples

Example 1: Married couple, AGI $100,000, unreimbursed medical expenses $18,000

  • 7.5% of AGI = $7,500
  • Deductible = $18,000 − $7,500 = $10,500

Example 2: Single filer, AGI $50,000, medical expenses $8,000

  • 7.5% of AGI = $3,750
  • Deductible = $8,000 − $3,750 = $4,250

These examples show why high out-of-pocket medical costs are more likely to produce meaningful tax savings for couples or families with combined expenses.

Final action plan (short checklist)

  1. Estimate your AGI and potential medical expenses now to see if you’re near the 7.5% threshold.
  2. If you’re close, consider timing or prepaying necessary care into the target year.
  3. Max out HSAs where appropriate before counting unreimbursed expenses on Schedule A.
  4. Keep receipts, EOBs, and a mileage log; consolidate records in one secure folder.
  5. Review results with a tax professional before filing — timing and treatment can vary with your personal situation.
