Medical Expense Deduction. You can deduct medical mileage as part of your overall medical expense deduction. The IRS limits the medical deduction to the amount of medical expenses in excess of 7.5 percent of your Adjusted Gross Income.
With the standard mileage rate, you take a mileage deduction for a specified number of cents for every business mile you drive. The IRS sets the standard mileage rate each year. For 2014, the rate was 56Â¢ per mile, and the 2015 rate is 57.5Â¢ per mile.To figure out your deduction, simply multiply your business miles by the applicable standard mileage rate.
