How Do You Report the Deduction on Your Tax Return? Once you have determined which medical care expenses you can include when figuring your deduction, you must report the deduction on your tax return. What Tax Form Do You Use? You report your medical expense deduction on Schedule A, Form 1040. You cannot claim medical expenses on Form 1040A or Form 1040EZ. An example of a filled-in medical and dental expense part of Schedule A is shown on page 17. How Do You Figure Your Deduction? To figure your medical and dental expense deduction, complete lines 1-4 of Schedule A, Form 1040, as follows: Line 1. Enter the amount you paid for medical expenses after reducing the amount by payments you received from insurance and other sources. Line 2. Enter your adjusted gross income from Form 1040, line 34. Line 3. Multiply the amount on line 2 (adjusted gross income) by 7.5% (.075) and enter the result. Line 4. If line 3 is more than line 1, enter zero. Otherwise, subtract the amount on line 3 from the amount on line 1. This is your deduction for medical and dental expenses. Bill and Helen's Schedule A Example. Bill and Helen Jones belong to a group medical plan and part of their insurance is paid by Bill's employer. They file a joint return, and their adjusted gross income is $33,000. The following medical expenses Bill and Helen paid this year have been reduced by payments they received from the insurance company. For themselves, Bill and Helen paid $375 for prescription medicines and drugs, $337 for hospital bills, $439 for doctor bills, $295 for hospitalization insurance, $380 for medical and surgical insurance, and $33 for transportation for medical treatment, which totals $1,859. For Grace Taylor (Helen's dependent mother), they paid $300 for doctors, $300 for insulin, and $175 for eyeglasses, which totals $775. For Betty Jones (Bill's dependent sister), they paid $450 for doctors and $350 for prescription medicines and drugs, which totals $800. Bill and Helen add all their medical and dental expenses together ($1,859 + $775 + $800 = $3,434). They figure their deduction on the medical and dental expenses part of Schedule A, Form 1040, as shown on the next page. Recordkeeping. For each medical expense, you must keep a record of the name and address of each person you paid, and the amount and date of the payment. When requested by the IRS, you must be able to substantiate your medical deduction with a statement or itemized invoice from the person or entity you paid showing the nature of the expense, for whom it was incurred, the amount paid, the date of payment, and any other information the IRS may deem necessary. Do not send these records with your return.
