How to claim medical tax deductions. Once you've totaled your medical expenses for the year, fill out the appropriate form in your tax return. If you include medical expenses in your itemized tax deductions, make sure to save your medical bills and payment statements as proof.
Generally speaking you can deduct your medical expenses, your spouseâs expenses, or your dependentâs (such as a qualifying child or relative) if you itemize your tax deductions. What Medical Expenses Can I Deduct? Please keep in mind that you can only claim the amount of your medical expenses that exceeds 7.5% of your adjusted gross income. Letâs say your AGI is $35,000. If your medical expenses for the year were $2,700 then you can deduct your expenses that were greater than 7.5% of your adjusted gross income. However, if your medical and dental expenses were only $1,750 then you could not claim any, as they didnât meet the requirement. The IRS has a huge list of medical expenses that you can deduct. Some common ones I think many people use include: 1  Ambulance/Transportation. 2  Annual Physical Exam. 3  Breastpump. 4  Chiropractor. 5  Dental Treatment. 6  Insurance Premiums. 7  Medicine. 8  Psychologist.
