Retirees who pay out of pocket for doctor visits, prescriptions, hearing aids, or a nursing home stay can claim a federal tax break for those costs, but the break only covers part of the bill. The Internal Revenue Service allows a deduction for medical and dental expenses only above a fixed share of income, a threshold that has sat at 7.5% for over a decade and is now written into the tax code as a permanent figure rather than something that changes each filing season.
How the 7.5% Floor Actually Works
The rule sounds simple in principle but trips up filers who assume the whole medical bill reduces taxable income; only the portion above the floor actually counts, and the floor itself is recalculated every year based on that year’s income rather than staying fixed in dollar terms.
The rule, laid out in the IRS’s Topic 502 guidance, applies to a taxpayer who itemizes deductions on Schedule A instead of taking the standard deduction. Only the portion of qualifying medical and dental expenses that exceeds 7.5% of adjusted gross income can be deducted, and that math resets every year based on that year’s income. A retiree with $50,000 in adjusted gross income, for example, would need to clear $3,750 in qualifying medical costs, which is 7.5% of that income, before a single dollar becomes deductible; a $10,000 medical year would only yield a $6,250 deduction, not the full $10,000. The deduction also only covers expenses paid for the taxpayer, a spouse, or a dependent that were not reimbursed by insurance or any other source.

What Counts as a Deductible Medical Expense
The IRS list of qualifying costs is broader than many filers assume. It covers fees paid to doctors, dentists, chiropractors, psychiatrists, psychologists, and other licensed practitioners; inpatient hospital or nursing home care, including meals and lodging, when the main reason for being there is medical care; prescription drugs and insulin; hearing aids, false teeth, prescription eyeglasses, contact lenses, crutches, and wheelchairs; a guide dog or other service animal for a person with a visual, hearing, or physical disability; and premiums paid for insurance covering medical care or qualified long-term care. Transportation counts too, including out-of-pocket car costs or the IRS medical mileage rate, plus tolls, parking, taxi or bus fare, and ambulance charges when the trip is primarily for medical care. Acupuncture, inpatient addiction treatment, smoking-cessation programs and the prescription drugs used to ease nicotine withdrawal, and a doctor-prescribed weight-loss program tied to a diagnosed disease can also qualify.
What Doesn’t Qualify
Some common costs are specifically excluded. Nonprescription medicine, toothpaste and general toiletries or cosmetics, most cosmetic surgery, funeral or burial expenses, and any trip taken purely for general health improvement rather than treatment of a specific condition do not count. The share of an insurance premium already paid by an employer, such as amounts run through a workplace cafeteria or premium-conversion plan, is not deductible unless that amount was already included as taxable wages on the taxpayer’s Form W-2. Nicotine gum or patches available without a prescription are excluded as well, even though prescription versions of the same product can qualify.
Why Itemizing Matters More in a High-Cost Year
The 7.5% floor only helps a taxpayer who itemizes, so a retiree whose annual medical costs stay modest may find the standard deduction is still the better option most years. The calculation changes in a year with a major medical event, such as surgery, a long hospital stay, or a move into a nursing home, when total qualifying expenses can climb high enough that itemizing on Schedule A produces a bigger deduction than the standard amount. According to IRS Publication 502, which lays out the deduction in full detail, taxpayers should track and total every qualifying expense across the year rather than assume smaller bills aren’t worth recording, since medical costs from multiple sources during one high-expense year can combine to clear the 7.5% floor even when no single bill looks large on its own.
Self-employed taxpayers with net earnings have a separate option worth knowing about: rather than running health insurance premiums through the 7.5% floor, a person who was self-employed, a partner with net self-employment earnings, or a more-than-2%-shareholder in an S corporation who received wages from it may be able to claim those premiums as a direct adjustment to income using Form 7206, separate from the itemized medical deduction described above. Any premium amount not claimed through that path can still be added to the itemized total on Schedule A instead.
Tracking Expenses Across the Year
Because the 7.5% floor applies to the combined total of every qualifying expense in a given year, keeping receipts and statements organized as the year goes matters more than trying to reconstruct spending at tax time. A single co-pay or prescription refill rarely clears the threshold on its own, but dental work, a hearing aid purchase, mileage to specialist appointments, and a portion of a long-term care insurance premium can add up to a meaningful deduction when combined on one return. Retirees managing several chronic conditions with multiple providers are the group most likely to clear the 7.5% floor in a typical year, simply because their qualifying costs tend to recur across dental, vision, hearing, mobility, and prescription categories at once rather than showing up as one large, memorable bill.
The deduction also interacts with other tax rules that retirees commonly navigate. A distribution taken from a traditional IRA or 401(k) to cover a medical bill still counts as taxable income when withdrawn, even though the medical expense it pays for might later qualify for the itemized deduction; the two are calculated separately rather than canceling each other out. Because the floor is based on adjusted gross income rather than taxable income, a retiree whose income shifts significantly from one year to the next, such as after taking a large IRA distribution or receiving a lump-sum payment, will see the dollar amount of the 7.5% threshold move with it, which is worth factoring in before timing an elective medical procedure around a particular tax year.
