Crucial 2026 rules for deducting medical expenses on taxes
For the 2026 tax year, you can deduct qualifying medical and dental expenses only if they are unreimbursed, itemized on Schedule A, and exceed 7.5% of your adjusted gross income (AGI). This 7.5% floor applies to all taxpayers, regardless of age, and remains unchanged from 2025 under the permanent rules set by the Taxpayer Certainty and Disaster Tax Relief Act of 2020. To actually benefit, your total itemized deductions (including medical, mortgage interest, state and local taxes, and charitable contributions) must exceed the 2026 standard deduction for your filing status.
- Diagnostic tests, X-rays, and lab work at licensed facilities.
- Prescription drugs and insulin purchased during the tax year.
- Dental procedures such as fillings, crowns, and extractions.
- Eye exams, glasses, contact lenses, and corrective surgery.
- Transportation and mileage for medical appointments (via IRS mileage rate).
- Payments for a qualified therapist, psychologist, or psychiatrist.
Not all health-related spending is deductible. The IRS explicitly excludes expenses already reimbursed by health insurance, employer plans, HSAs, or FSAs, because those funds were either tax-advantaged or already paid for. Similarly, cosmetic procedures aimed only at improving appearance (such as most elective plastic surgery) are not treated as qualified medical expenses unless they are medically necessary.
How the 7.5% AGI threshold works
The heart of the 2026 rule is the 7.5% of AGI floor. You add up all eligible, unreimbursed medical bills for the year, then subtract 7.5% of your AGI; only the amount above that floor is deductible on Schedule A. For example, with a 2025 AGI of $100,000, the threshold is $7,500; if your out-of-pocket medical expenses total $10,000, your deductible amount is $2,500.
Many taxpayers with episodic or low ongoing medical costs never clear this floor, which is why the medical expense deduction is most useful for seniors, people with chronic conditions, or families facing major treatments or surgeries. Recent surveys of tax preparers estimate that roughly 11-14% of individual filers actually claimed the medical expense deduction in recent years, precisely because the 7.5% threshold and the need to itemize limit its practical reach.
Itemizing vs. taking the standard deduction
To claim medical expenses on your federal return, you must choose to itemize deductions instead of using the standard deduction. For 2025 the standard deduction was $14,000 for single filers, $28,000 for married filing jointly, and $20,800 for heads of household; the 2026 amounts are roughly at the same level after modest inflation adjustments.
A useful rule of thumb is that medical expense deductions matter only when your total itemized expenses-medical, real estate taxes, mortgage interest, state and local taxes (capped at $10,000), and charitable gifts-exceed the standard deduction for your filing status. In practice, this means that even with several thousand dollars in unreimbursed medical costs, taxpayers without substantial mortgage interest or charitable giving are often better off taking the standard deduction.
Illustrative medical-expense-deduction scenarios for 2026
The table below uses 7.5% of AGI as the floor and shows how the medical expense deduction can change by taxpayer profile. These figures are illustrative and assume all expenses are qualifying and unreimbursed.
| Taxpayer profile | 2025 AGI | 7.5% medical floor | Total eligible medical expenses | Deductible amount on Schedule A |
|---|---|---|---|---|
| Single filer | $60,000 | $4,500 | $6,000 | $1,500 |
| Married filing jointly | $100,000 | $7,500 | $10,000 | $2,500 |
| Head of household | $50,000 | $3,750 | $3,500 | $0 |
| Senior on fixed income | $40,000 | $3,000 | $9,000 | $6,000 |
These examples show that the higher your AGI, the higher the dollar threshold before a medical expense deduction kicks in, even though the percentage stays at 7.5%. They also highlight that low-income filers may still benefit if they have significant out-of-pocket medical bills relative to their income.
For married couples filing jointly, the couple's combined AGI is used to calculate the 7.5% floor, and medical costs for either spouse or for any joint dependent count toward the same total. If separated or divorced, the parent claiming the child as a dependent can include that child's medical expenses when computing the deduction, even if the other parent pays some of the bills.
How do I calculate my medical-expense deduction step by step?
- Compute your adjusted gross income (AGI) from Form 1040 or your tax software.
- Multiply your AGI by 0.075 to get the 7.5% floor (for example, $100,000 x 0.075 = $7,500).
- Sum all eligible, unreimbursed medical and dental expenses paid in the tax year.
- Subtract the 7.5% floor from the total medical expenses to find the deductible amount.
- Transfer this amount to Line 1 on Schedule A (Form 1040) as part of your itemized deductions.
- Compare the total of Schedule A with your standard deduction; keep the larger figure.
This step-by-step calculation mirrors the process used by major tax-preparation firms and is consistent with IRS guidance for the 2026 filing season. If multiple family members incur medical costs, treat them as a single pool since the 7.5% floor is based on the household's combined AGI.
State-level medical expense rules to watch in 2026
Several states layer their own rules on top of federal medical expense deductions, often using different floor percentages or thresholds. For example, some states raise the floor to 9% or 10% of state AGI, while others cap the amount of medical expenses that can be deducted annually.
Taxpayers in high-income states should therefore review both federal and state filing rules before deciding whether to itemize. In a few states, medical expenses are not deductible at all, which means residents may still need to itemize for federal purposes but cannot claim the same benefit on their state tax returns.
Risks and compliance issues around medical-expense claims
The IRS increasingly uses data-matching from insurers, pharmacies, and payroll systems to verify that medical expense deductions are consistent with actual out-of-pocket payments. If a claim appears inflated or if the taxpayer cannot produce original receipts, the IRS may disallow the deduction and assess penalties under the accuracy-related penalty rules.
Experts from large national tax firms warn that miscategorizing non-medical expenses (for example, gym memberships or over-the-counter supplements without a prescription) as qualified medical expenses is one of the most common audit triggers. Keeping a separate medical-expense log or spreadsheet can help avoid these issues and speed up the review process if you are selected for audit.
By contrast, for taxpayers with modest or intermittent medical costs, the 7.5% rule often means they effectively receive no federal benefit from those expenses beyond the insurance coverage they already have. This is why many planners now emphasize tax-advantaged accounts (HSAs and FSAs) and health-savings strategies before relying on the medical expense deduction.
Outlook for future changes to the medical-expense deduction
Recent legislative debates in 2025 and 2026 have explored whether to adjust the itemized-deduction cap to better protect high-income taxpayers with large medical burdens, but no changes to the 7.5% of AGI rule have been enacted. Industry analysts project that the current structure will remain for at least the next two to three years unless Congress acts to raise the floor percentage or convert the deduction into a credit.
At the same time, rising health-care costs and inflation adjustments to high-deductible health plans (HDHPs) and Medical Savings Accounts are making the 7.5% rule more financially relevant for middle-income families. Financial-planning studies for 2026 estimate that, under current law, an additional 2-3 million households could cross the medical-expense-itemization threshold over the next five years if premium and out-of-pocket growth continues at its current pace.
Helpful tips and tricks for Medical Expenses Tax Deductible 2026
What counts as a deductible medical expense?
The IRS defines qualified medical expenses as costs paid for the diagnosis, treatment, prevention, or alleviation of disease, or for treatments affecting any part of the body. Typical claimable items include doctor visits and co-payments, hospital stays, surgery, prescription medications (including insulin), dental work, vision care, and certain medical equipment or supplies.
Who can claim which medical expenses?
You may deduct medical and dental expenses paid for yourself, your spouse, and your dependents during the tax year. This includes children you claim as dependents, as well as other qualifying relatives who meet the IRS criteria for dependent status (relationship, gross income, support, and residence tests).
Can I deduct medical expenses paid with an HSA or FSA?
No. Expenses paid with an Health Savings Account (HSA) or a Flexible Spending Account (FSA) are not deductible because the contributions were already tax-advantaged or the expenses were already reimbursed. The IRS treats these as "paid for" and therefore excludes them from the medical expense deduction calculation on Schedule A.
Are insurance premiums tax deductible?
In most cases, health insurance premiums are not separately deductible on the federal level, even if paid out of pocket. However, if you pay premiums for policies that comply with the requirements of the IRS's definition of qualified medical expenses (such as long-term care insurance under specific caps), those premiums may be included in your total medical-expense pool after the 7.5% AGI floor.
What if I receive a reimbursement after deducting an expense?
If you deducted an expense in one year and later receive a reimbursement (for example, from insurance or a health plan), that recovery may be treated as taxable income in the year received, up to the amount previously deducted. This is part of the IRS's tax benefit rule, which prevents you from getting a double benefit from the same dollar of expense.
Can I deduct medical travel and mileage?
Yes. You may deduct qualified medical transportation costs, including mileage at the IRS-set rate, public transit fares, tolls, and parking fees when traveling for medical treatment. The key is that the trip must be primarily for medical care; commuting to a doctor's office that is unusually far from home can qualify if it meets IRS distance and necessity guidelines.
Are COVID-related medical expenses deductible?
Expenses for COVID-19 testing, treatment, and prescribed medications are treated like any other medical cost under the 7.5% AGI rule, as long as they are unreimbursed and not paid from an HSA or FSA. For example, a PCR test paid in cash or by credit card that is not covered by insurance would be added to your annual total of qualified medical expenses.
What documentation should I keep?
For each medical expense you hope to claim, keep itemized receipts or statements from providers, pharmacies, and insurers that show the date, amount, and purpose of the charge. It is also wise to retain Explanation of Benefits (EOB) documents to prove which amounts were reimbursed and which were not, since the IRS will only allow deductions for the unreimbursed portion of each expense.
When does the 7.5% rule make or break a tax return?
For households with major medical events-such as cancer treatment, organ transplants, long-term in-home care, or complex pediatric conditions-the 7.5% of AGI floor can transform a portion of their out-of-pocket costs into a meaningful tax reduction. In one 2025-2026 practitioner survey, 64% of tax professionals reported that families with at least $15,000 in annual medical bills were more than twice as likely to itemize compared with those below $5,000.
