Medical Expense Deduction 2026: The 7.5% Rule, What Qualifies, and How to Actually Claim It

June 2026 Snapshot: Why Most People Cannot Deduct Their Medical Bills (and When You Can)

Here is a fact that surprises almost everyone at tax time: the medical expense deduction exists, but most people who try to use it get nothing. That is not a glitch. It is exactly how the rule is designed. The IRS allows a deduction for medical and dental expenses, but only for people who clear two separate hurdles in the same year.[1]

The first hurdle is that you must itemize your deductions on Schedule A. You cannot take the standard deduction and also deduct medical bills. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. Those amounts are so large that the great majority of taxpayers simply take the standard deduction and stop there.[6, 8]

The second hurdle is the famous 7.5% floor. You can only deduct the portion of your qualified medical costs that is more than 7.5% of your adjusted gross income (AGI). If your AGI is $80,000, the first $6,000 of medical spending does not count at all. Only dollars above that line are deductible. In plain terms, this is a deduction built for a "bad" medical year, not for routine checkups and prescriptions.[1, 3]

The Two Gates: Itemizing and the 7.5% Floor

Think of the medical deduction as a door with two locks. The first lock is the choice between itemizing and the standard deduction. Tax law lets you take the larger of the two, but never both. You only benefit from medical expenses if your total itemized deductions — medical, state and local taxes, mortgage interest, charitable gifts — add up to more than your standard deduction.[7]

The second lock is the 7.5% floor. Here is a simple worked example. Suppose your AGI is $80,000 and you paid $10,000 in qualified medical bills during the year. First, multiply your AGI by 7.5%: $80,000 × 0.075 = $6,000. That is your floor. Then subtract it from your costs: $10,000 − $6,000 = $4,000. So $4,000 is your potential medical deduction — but only if you itemize and your total itemized deductions beat the standard deduction.[1]

One more rule worth knowing up front: you can include the bills you paid for yourself, your spouse, and your dependents. The law defines a wide circle of "medical care," covering the diagnosis, cure, treatment, or prevention of disease for the people in your tax household. We will go through exactly what qualifies — and what does not — in the sections below.[3]

How the 7.5% AGI Floor Actually Works

The floor is calculated on Schedule A, lines 1 through 4. You put your total qualified medical expenses on line 1, your AGI on line 2, multiply that AGI by 7.5% on line 3, and the difference flows to line 4. Line 4 is the number that actually joins the rest of your itemized deductions. If your expenses are below the 7.5% line, line 4 is simply zero.[4]

A higher income makes the floor harder to clear, because 7.5% of a big AGI is a big number. A retiree with a $40,000 AGI only needs to spend more than $3,000 to start deducting. A household with a $200,000 AGI needs to clear $15,000 first. This is why the deduction tends to help two groups the most: people with modest incomes and people with a genuinely expensive medical year — a major surgery, a long hospital stay, fertility treatment, or sustained long-term care.[1]

It is worth remembering that 7.5% is the permanent floor. For years the threshold bounced between 7.5% and 10% depending on the law in effect, which caused real confusion. Today the statute fixes it at 7.5% of AGI for all taxpayers, so you can plan around that number with confidence.[3]

What Counts as a Medical Expense

The list of qualified costs is broader than most people expect. IRS Publication 502 covers payments to doctors, dentists, surgeons, psychiatrists, and psychologists; hospital and nursing care; prescription medicines and insulin; and equipment such as eyeglasses, contact lenses, hearing aids, crutches, and wheelchairs. Dental work and vision care both count, which surprises many filers.[2, 1]

Some less obvious items also qualify. Mental health therapy and treatment for substance use disorders count, as do smoking-cessation programs. A weight-loss program counts when a doctor prescribes it for a specific diagnosed disease such as obesity or hypertension — but not for general health. Fertility treatments, guide dogs and other service animals, and special schooling for a child with a diagnosed condition can all be included.[2]

A useful rule of thumb: an expense qualifies when its main purpose is to diagnose, treat, cure, or prevent a disease, or to affect a function of the body. That is the legal test, and it is why a therapeutic treatment counts while a spa day does not. When in doubt, keep the receipt and the doctor's note that ties the cost to a medical condition.[3]

Health Insurance Premiums: The After-Tax Rule

Insurance premiums can be one of the largest medical costs, and many of them are deductible — but only if you paid them with after-tax money. Publication 502 lets you include premiums for medical and dental coverage, Medicare Part B and Part D, Medicare supplement (Medigap) policies, and COBRA continuation coverage, among others.[2]

The catch is the most common one of all: if your employer takes your premium out of your paycheck before taxes — which is how nearly all workplace plans operate — you cannot deduct it. The money was never taxed in the first place, so you do not get a second break. Trying to deduct pre-tax premiums is one of the most frequent mistakes the IRS sees on Schedule A.[2]

Marketplace coverage has its own twist. If you buy a plan through the Health Insurance Marketplace and receive the Premium Tax Credit, you can only deduct the portion of the premium you actually paid out of pocket — not the part covered by the advance credit. The credit already lowered your cost, so that subsidized amount is off the table for the deduction.[17]

Long-Term Care Insurance: Deductible Within Age Limits

Premiums for a qualified long-term care (LTC) insurance policy count as a medical expense, but with a special cap that rises with your age. For 2026, the per-person deductible limit set by Rev. Proc. 2025-32 is $500 if you are age 40 or under, $930 for ages 41–50, $1,860 for ages 51–60, $4,960 for ages 61–70, and $6,200 if you are over 70.[6, 3]

These limits matter because LTC premiums climb steeply with age, and a 75-year-old can easily pay far more than the $6,200 cap. Only the amount up to the age-based limit counts toward your medical deduction. If you are weighing whether such a policy is worth it, our long-term care insurance guide walks through the trade-offs in detail.[3]

Travel, Mileage, and Lodging for Medical Care

Getting to care counts, too. If you drive your own car for medical reasons, you can deduct the actual gas and oil costs, or simply use the IRS standard rate. For 2026, Notice 2026-10 sets the medical mileage rate at 20.5 cents per mile, down half a cent from 2025. You can add parking fees and tolls on top of the mileage.[10, 11]

Other travel costs can qualify when the trip is primarily for, and essential to, medical care: ambulance service, bus, taxi, train, or plane fares, and even lodging. Lodging is capped at $50 per night, per person (so a parent traveling with a sick child can count $100), and it cannot include meals. As always, only the medical part of a trip counts — a vacation that happens to include a doctor visit does not.[2]

What You Cannot Deduct

The "no" list is just as important as the "yes" list. Topic 502 rules out purely cosmetic procedures, general-health items like gym memberships, and most vitamins or supplements unless a doctor prescribes them to treat a specific diagnosed condition. Toiletries, cosmetics, and funeral or burial costs are also excluded.[1]

Over-the-counter medicines are generally not deductible either — with one big exception: insulin is allowed even without a prescription. And you can never deduct an expense that was reimbursed by insurance or that you paid with pre-tax dollars. If a cost did not actually come out of your own taxed money, it does not belong on Schedule A.[2]

No Double-Dipping: HSAs, FSAs, and Reimbursements

This is the rule that trips people up most. If you paid a medical bill with money from a Health Savings Account (HSA), a Flexible Spending Account (FSA), an Archer MSA, or an HRA, you cannot also deduct it. Publication 969 states it plainly: you can't claim an itemized deduction for expenses equal to a tax-free distribution from those accounts. That money was already tax-free going in, so deducting it would be a second, forbidden tax break.[12, 2]

For most people, an HSA is actually the better tool, because it gives a tax break with no 7.5% floor and no need to itemize. A health FSA through a cafeteria plan works similarly with pre-tax dollars. A smart order of operations is to pay routine costs from these accounts first, and reserve the itemized deduction for any large, out-of-pocket bills that remain. Our HSA guide explains how to use one well.[13, 14]

Self-Employed? You Get a Separate, Better Deduction

If you work for yourself, do not bury your health insurance in the medical itemized deduction. A separate and far more generous rule exists. Under section 162(l), a self-employed person can deduct 100% of health, dental, and qualified long-term care premiums for themselves, a spouse, and dependents — with no 7.5% floor and no need to itemize.[15]

You figure this deduction on Form 7206 and report it as an adjustment to income on Schedule 1, line 17 — an "above-the-line" deduction that lowers your AGI directly. Two limits apply: the deduction cannot exceed your net self-employment earnings, and you cannot claim it for any month you were eligible to join an employer's plan (including a spouse's). If you are self-employed, our self-employment tax guide covers the rest of your tax picture.[16]

Itemize or Take the Standard Deduction in 2026?

Because medical expenses only help if you itemize, the whole decision turns on one comparison: do your itemized deductions beat the standard deduction? For 2026, the standard deduction is $16,100 (single), $32,200 (married filing jointly), and $24,150 (head of household). Taxpayers age 65 or older get an extra standard deduction on top of those amounts.[9, 6]

Since the standard deduction roughly doubled in 2018, the large majority of filers no longer itemize — only those with big mortgage interest, large state-and-local tax bills, generous charitable gifts, or a heavy medical year usually clear the bar. Publication 501 walks through who should itemize. The honest takeaway: add up everything on Schedule A first, then itemize only if the total wins.[8]

This is where a strategy called "bunching" comes in. If your expenses are close to the line, you can sometimes push elective procedures, dental work, or a planned surgery into a single calendar year, so that one year clears both the 7.5% floor and the standard-deduction hurdle. The other years, you take the standard deduction. The same logic links to your other write-offs — see our guides to the SALT deduction and charitable giving.[7]

Special Situations: Dependents, Divorce, and Home Improvements

A few situations have their own rules. You can deduct medical bills you paid for a dependent, including an aging parent you support, even if that parent is not claimed on your return because of the income test — as long as the other dependent tests are met. For divorced or separated parents, a special rule lets each parent deduct the medical costs they personally paid for a child, regardless of who claims the child as a dependent.[2]

Larger items can qualify too. The cost of a capital improvement made for a medical reason — a wheelchair ramp, widened doorways, a stair lift, or a chair lift — counts as a medical expense, but you must subtract any increase it adds to your home's value. Nursing home fees count when the main reason for being there is medical care. And the executor of an estate can deduct a decedent's final medical bills on the right return.[2]

How to Claim the Deduction, Step by Step

The mechanics are straightforward once the rules are clear. Total your qualified expenses for the year, subtract anything reimbursed by insurance or paid from an HSA or FSA, and enter the result on Schedule A, line 1. The form then subtracts 7.5% of your AGI and carries the remainder into your total itemized deductions. Keep receipts, statements, and a mileage log; you do not file them, but you need them if the IRS ever asks.[5, 4]

If you are unsure whether a particular cost qualifies, the IRS offers a free Interactive Tax Assistant that walks you through the question in a few minutes. Seniors can also lean on Publication 554, the Tax Guide for Seniors, which highlights the medical-expense and standard-deduction rules that matter most after 65.[19, 18]

Smart 2026 Strategies to Make Medical Expenses Count

Pull the pieces together and a clear playbook emerges. First, bunch elective and planned care into a single year when you can, so one year clears the 7.5% floor and the standard-deduction hurdle. Second, pay deductible bills by December 31 — the expense counts in the year you pay it, not the year you are billed. Third, fund an HSA or FSA first for routine costs, and save the itemized deduction for the big, unreimbursed bills.[1]

Finally, log every medical mile, keep your receipts organized, and remember the age-based long-term care limits if you carry that coverage. This guide is educational and not personalized tax advice; the rules have exceptions, and your situation may differ. For your own return, confirm the details with the linked IRS sources, the IRS's Topic 502, or a qualified tax professional before you file.[1]
