Your medical expenses may save you money at tax time, but a few key rules apply. Here are some tax tips to help you determine if you can claim a tax deduction:
- You must itemize. You can only claim your medical expenses that you paid for in 2014 if you itemize deductions on your federal tax return. If you take the standard deduction, you can’t claim these expenses.
- AGI threshold. You include all the qualified medical costs that you paid for during the year. However, you can only deduct the amount that is more than 10 percent of your adjusted gross income.
- Temporary threshold for age 65. If you or your spouse is age 65 or older, the AGI threshold is 7.5 percent of your AGI. This exception applies through Dec. 31, 2016.
- Costs to include. You can include most medical and dental costs that you paid for yourself, your spouse and your dependents. Exceptions and special rules apply. Costs reimbursed by insurance or other sources do not qualify for a deduction.
- Expenses that qualify. You can include the costs of diagnosing, treating, easing or preventing disease. The costs you pay for prescription drugs and insulin qualify. The costs you pay for insurance premiums for policies that cover medical care qualify. Some long-term care insurance costs also qualify. For more examples of costs you can and can’t deduct, see IRS Publication 502, Medical and Dental Expenses. You can get it on IRS.gov/forms anytime.
- Travel costs count. You may be able to claim travel costs you pay for medical care. This includes costs such as public transportation, ambulance service, tolls and parking fees. If you use your car, you can deduct either the actual costs or the standard mileage rate for medical travel. The rate is 23.5 cents per mile for 2014.
- No double benefit. You can’t claim a tax deduction for medical expenses you paid for with funds from your Health Savings Accounts or Flexible Spending Arrangements. Amounts paid with funds from those plans are usually tax-free. This rule prevents two tax benefits for the same expense.
- Use the tool. You can use the Interactive Tax Assistant tool on IRS.gov to see if you can deduct your medical expenses. The tool can answer many of your questions on a wide range of tax topics.
