If you or a dependent has Celiac Disease or another medically documented condition that requires a special diet, you may be able to deduct additional costs for gluten-free foods or specialty products. Discuss these expenses with your accountant to determine what qualifies as a medical deduction.

Currently, taxpayers who itemize can deduct qualified unreimbursed medical expenses that exceed a percentage of their adjusted gross income. The applicable threshold has changed over time, so check the rules for the tax year you are filing.

Recent thresholds for medical expense deductions

The deduction threshold has varied: it was 7.5% of adjusted gross income for some years, rose to 10% for a period, and in recent years has returned to 7.5% for certain tax years. Always confirm the correct percentage for the tax year in question before claiming deductions.

IRS definition of allowable medical and dental expenses

Which expenses can I deduct for a gluten-free diet?

If your total medical expenses for the year exceed the required percentage of your adjusted gross income, you may be able to deduct the portion of gluten-free food costs that represents the difference between those items and comparable regular products. In addition, items bought solely because of the medical diet—products with no direct regular-food equivalent—are typically fully deductible. Reasonable shipping charges for specialty items purchased online are also generally deductible when they are part of a medically necessary diet.

Pro tip: When totaling medical expenses, include all allowable items such as doctor visits, prescription medications, insurance premiums (where allowed), dental care, and medical mileage. These common medical costs can add up and help you reach the deduction threshold when combined with special-diet expenses.

Always consult a tax professional about deductions related to Celiac Disease or other medically necessary diets before filing.

According to organizations focused on Celiac Disease, individuals with a formal medical diagnosis may qualify for tax deductions for gluten-free foods, though specific documentation and careful recordkeeping are essential to support any claim.

Steps to document and claim special-diet or gluten-free deductions

Follow these steps to prepare for claiming special-diet-related medical expenses:

Step 1: Obtain written medical documentation

Ask your physician for a written diagnosis or medical recommendation that states the need for a gluten-free or other specialized diet. Keep the original or a clear copy with your tax records as evidence to support the deduction.

Step 2: Save receipts

Retain receipts for all purchases of gluten-free groceries, specialty foods, supplements, and any other diet-specific items. Record the date, vendor, and item description to make it easier to justify deductions if questioned.

Step 3: Calculate the deductible difference

Compare the cost of gluten-free items to the price of the most comparable regular foods. The difference in cost is the portion generally treated as a medical expense. For example, if standard flour costs $0.89 per pound and a specialty gluten-free flour costs $3.25 per pound, the $2.36 difference per pound may be deductible. Items purchased solely for the special diet (for example, certain gluten-free baking ingredients with no common alternative) can be deducted in full.

Also include reasonable shipping costs and handling fees for diet-specific items bought online when calculating your total medical expenses.

Step 4: File your claim

Report allowable medical expenses on the appropriate tax forms when you itemize deductions (for example, Schedule A of Form 1040 where applicable). Useful references include IRS Publication 502 and relevant revenue rulings and tax court memoranda. Keep copies of your physician’s note, receipts, and calculations with your tax records in case you need to substantiate the claim.

  • IRS Publication 502 (Medical and Dental Expenses)
  • Relevant revenue rulings and tax court decisions cited by your tax professional

You can cite these references in your tax paperwork as support for the deduction.

Restaurant meals may be deductible when they are part of a medically necessary diet, but documentation is crucial. Keep receipts and, if possible, notes on the receipt or an allergy/special request designation that explains the medical necessity. Clear documentation increases the likelihood that a restaurant purchase will be accepted as a medical expense.
