Can You Write Off a Medical Wig as a Medical Expense on Taxes?

When you are facing medical hair loss from chemotherapy, alopecia, radiation, or burns, the cost of a high-quality wig, often called a cranial prosthesis, can feel overwhelming. The good news: under certain conditions, a medical wig may qualify as a tax-deductible medical expense.

Here is what to know about when a wig counts as a write-off, how to claim it, and what documentation you will need.

IRS Rules on Medical Expenses

Per the IRS, some out-of-pocket medical expenses are deductible if they are primarily intended to treat or alleviate a medical condition. This falls under IRS Publication 502, Medical and Dental Expenses. A wig can qualify if:

• It is prescribed by a physician for medical reasons, such as hair loss from disease or treatment.
• It is considered necessary for the patient's medical care or mental health.

Without a prescription, the IRS treats wigs as cosmetic, and they are not deductible.

How to Claim It

1. Get a doctor's prescription. It should clearly state the wig is for medical treatment (a cranial prosthesis for alopecia, chemotherapy, burns, or radiation).
2. Keep detailed records. Save your purchase receipt, the physician's order, and any related insurance paperwork.
3. Itemize your deductions. Wig costs join your other out-of-pocket medical expenses and are deductible only on the portion that exceeds 7.5% of your adjusted gross income for the year.

Sales Tax Exemption vs. Income Tax Deduction

• California sales tax: wigs prescribed for medical hair loss are exempt at the time of purchase. Read our full guide to the California exemption.
• IRS deduction: a prescribed wig can also be claimed as a deductible medical expense on your federal return, and in some cases your state return.

In other words, you may benefit twice: skip sales tax at purchase, then claim the expense at tax time.

Insurance vs. Deduction

• If insurance covers part of your wig, only the portion you paid out of pocket can be included for tax purposes.
• If insurance does not cover wigs, your full expense may be deductible with a prescription.
