Medical Expense Deduction Calculator

This calculator helps you determine how much of your qualified medical expenses you can deduct on your 2026 federal income tax return. For 2026, the IRS allows taxpayers to deduct the amount of medical expenses that exceeds 7.5% of their Adjusted Gross Income (AGI). Understanding this deduction can significantly reduce your taxable income, potentially leading to substantial tax savings.

The calculation is straightforward: first, we determine your AGI threshold by multiplying your 2026 AGI by 7.5%. Next, we subtract this threshold amount from your total qualified medical expenses. The resulting figure is your deductible medical expense amount. If your total medical expenses are less than or equal to the 7.5% AGI threshold, your deductible amount will be zero.

Remember to only include 'qualified' medical expenses, which generally means payments for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for treatments affecting any structure or function of the body. Keep meticulous records of all medical expenses, including receipts and statements, as the IRS may request documentation. A common mistake is including non-qualified expenses or forgetting to include all eligible expenses, so review IRS Publication 502 carefully.
