The IRS allows you to deduct qualified medical expenses that exceed 7.5% of your adjusted gross income for 2017 and 2018. Beginning Jan. 1, 2019, all taxpayers may deduct only the amount of the total unreimbursed allowable medical care expenses for the year that exceeds 10% of their adjusted gross income.
Your adjusted gross income (AGI) is your taxable income minus any adjustments to income such as deductions, contributions to a traditional IRA and student loan interest.
For example, if you have an adjusted gross income of $45,000 and $5,475 of medical expenses, you would multiply $45,000 by 0.075 (7.5 percent) to find that only expenses exceeding $3,375 can be deducted. This leaves you with a medical expense deduction of $2,100 (5,475 – 3,375).
The IRS allows you to deduct preventative care, treatment, surgeries and dental and vision care as qualifying medical expenses. You can also deduct visits to psychologists and psychiatrists. Prescription medications and appliances such as glasses, contacts, false teeth and hearing aids are also deductible.
The IRS also lets you deduct the expenses that you pay to travel for medical care such as mileage on your car, bus fare and parking fees.
Any medical expenses for which you are reimbursed, such as by your insurance or employer, cannot be deducted. In addition, the IRS generally disallows expenses for cosmetic procedures. You cannot deduct the cost of non-prescription drugs (except insulin) or other purchases for general health such as toothpaste, health club dues, vitamins or diet food, non-prescription nicotine products or medical expenses paid in a different year.
To claim the medical expenses deduction, you must itemize your deductions. Itemizing requires that you not take the standard deduction, so you should only claim the medical expenses deduction if your itemized deductions are greater than your standard deduction (TurboTax will do this calculation for you).
If you elect to itemize, you must use IRS Form 1040 to file your taxes and attach Schedule A.
