May I deduct a wig I needed as a result of chemotherapy?

UPDATED FOR TAX YEAR 2019

Yes. Wigs are deductible if they are purchased for chemotherapy-induced hair loss.  Medical, dental, and vision expenses are reported on Schedule A and entered in the Deductions & Credits section.

Please keep in mind the following about deducting your medical expenses, including health insurance:

• You don't get the benefit if you are taking the standard deduction.
• If you itemize deductions, you will only be able to take total medical expenses that are greater than 7.5% of your adjusted gross income

To enter your medical expenses, please follow these steps:

1. Click on Taxes > Deductions & Credits 
2. In the Medical section, click on the Start/Revisit box next to Medical Expenses.  
3. If you haven't yet entered any medical expenses, TurboTax will ask you if your total medical expenses exceed a certain number.  [That's the 7.5% AGI mentioned above.]    
4. If you think your total medical expenses will exceed that number, click the blue Yes box and continue through the interview, entering the requested information on your medical expenses.
