Can You Claim a Wig on Your Taxes? What Canadians Losing Hair to Illness Should Know

Hair loss during cancer treatment arrives with a long list of worries, and money is rarely at the top of it. Then the first quote for a good wig lands, sometimes well over a thousand dollars for real hair, and the practical questions start. Will insurance pay? Can you claim a wig on your taxes? The short answer to the second question is yes, under specific conditions that very few people are told about in the oncology waiting room. The Canada Revenue Agency lists wigs among eligible expenses in its guide to medical expenses, as long as the person has suffered abnormal hair loss because of a disease, an accident or a medical treatment, and a prescription is on file. October is Breast Cancer Awareness Month, so this is a good time to lay out how the rule works, what it is worth in dollars, and where people most often leave money on the table.

Who can claim a wig, and under what conditions

The CRA wording is short, and every word counts. The wig must be for someone who has experienced abnormal hair loss, and that loss must be caused by a disease, an accident or a medical treatment. Chemotherapy is the most common case, but it is not the only one. Hair loss after a serious accident or linked to an autoimmune condition can qualify too, provided a medical practitioner puts it in writing.

What does not qualify is just as important. Ordinary age-related thinning is not covered, and the CRA specifically excludes cosmetic procedures, including hair replacement procedures, from eligible expenses. A wig bought purely for style, even an expensive one, stays a personal purchase.

The claim can cover you, your spouse or common-law partner, and your children under 18. A separate line allows you to claim expenses you paid for other relatives who depend on you, such as a parent going through treatment, under slightly different rules.

For families, that second line matters more than it seems. Adult children often end up paying for a parent’s wig, medication and travel to appointments. Those costs can be claimed, but the threshold is then based on the dependant’s net income, not yours, and the calculation is done separately for each person. When a parent has a modest pension, the threshold can be low enough that a good part of the expense counts.

Claim the full picture, not just the wig

Here is the catch that surprises most people. The medical expense tax credit is not a dollar-for-dollar refund. You add up all your eligible medical expenses for a chosen 12-month period, then subtract a threshold: for the 2025 tax year, the lesser of $2,834 or 3% of your net income. Only the amount above that threshold counts, and the federal credit is then calculated at the lowest tax rate.

That is why a wig claimed on its own often seems to produce nothing. Claimed together with the rest of the year’s eligible costs, it can make a real difference. Prescription drugs, dental work, eyeglasses, private health plan premiums and, for someone treated for breast cancer, a breast prosthesis after a mastectomy with a prescription, can all end up on the same line.

The provincial credit comes on top. In Ontario, the provincial amount is calculated separately, and the rules and thresholds may differ, so the final tax saving is somewhat higher than the federal figure alone. Numbers in this table are an illustration, not tax advice. A tax preparer can run your real situation in a few minutes.

Two details from the CRA guide are worth underlining. First, the 12-month period does not have to match the calendar year. If treatment started in spring, choosing a window from April to March can capture more expenses in a single claim. Second, it is often better for the spouse with the lower net income to make the claim, because 3% of a smaller income is a smaller threshold. The CRA’s own worked example in the guide shows exactly that.

Insurance first, taxes second

Private insurance deserves a look before the tax return does. Many group health plans reimburse part of the cost of a wig for medical hair loss, sometimes up to a yearly or lifetime maximum. Plans often use the term “cranial prosthesis” rather than “wig”, so it helps to search your benefits booklet for both.

Keep in mind that the tax credit applies only to the portion of an expense that has not been and will not be reimbursed. If your plan pays $500 on a $2,200 wig, you can claim the remaining $1,700. Claiming the full price when part of it was reimbursed is a mistake the CRA can catch on review.

The paperwork is the same for both. Ask your doctor or oncologist for a short written prescription that mentions the hair loss and its medical cause. Keep the receipt, and make sure it shows the seller’s name, the date, the patient’s name and what was purchased. The CRA doesn’t want those documents with your return, but it can ask for them later, and a receipt that just says “hair accessory” will not help.

Choosing a wig that is worth claiming

The tax credit softens the bill. It does not choose the wig for you, and the decision deserves more care than it usually gets in the middle of treatment.

Synthetic wigs cost less, hold their style after washing and are easier to care for, which suits many people during chemotherapy when energy is low. Human hair looks and moves more naturally, can be heat-styled and coloured, and lasts longer with proper care, but it asks more of its owner. A scalp made sensitive by treatment also changes the equation: a soft, breathable cap and a good fit matter more than the fibre.

Fit is the part online shopping gets wrong most often. Head circumference, cap construction and the hairline all need to be checked in person or with someone who knows what to look for.

Not everyone needs a full wig, either. When hair thins in patches or mostly on top, a topper, a partial hairpiece that clips into existing hair, can be lighter, cooler and more comfortable. The CRA guide only mentions wigs, so if you plan to claim a topper prescribed for medical hair loss, confirm with a tax professional first. Ask the prescribing doctor to describe the need rather than a specific product, so the prescription covers what you actually end up buying. Specialized boutiques offer private fittings for exactly this reason. RL Moda, a Quebec wig specialist with a boutique in Montreal, works by appointment and sells both synthetic styles and human hair wigs online, along with the adhesives, tapes and care products that keep a hairpiece comfortable day after day.

My most useful advice is also the simplest: shop before the hair is gone. Matching colour, density and hairline is far easier while there is still something to match, and it turns a stressful purchase into one decision made calmly, early, with the prescription and the receipts already in the right folder.

Frequently asked questions

Can you claim a wig on your taxes in Canada?

Yes, if the wig is for someone who suffered abnormal hair loss because of a disease, an accident or a medical treatment, and a medical practitioner has prescribed it. You can claim it as a medical expense on your federal return.

Do I need a prescription for a wig to be tax deductible?

Yes. The CRA lists wigs as an eligible medical expense with a prescription required. Keep it with your receipt in case the CRA asks for documents.

How much will I get back for a wig on my taxes?

It depends on your total medical expenses and income. Only the amount above the lesser of $2,834 or 3% of net income (2025) counts, and the federal credit is then calculated at 14.5%, plus a provincial credit.

Does insurance cover wigs for cancer patients?

Many group health plans cover part of the cost, often under the term “cranial prosthesis”. You can then claim only the unreimbursed portion on your tax return.
