Managing the Finances of Celiac Disease for Someone You Love

Most celiac financial guides assume the patient and the taxpayer are the same person.

If you have celiac disease yourself, the financial picture is straightforward: your expenses go on your Schedule A, your HSA card pays for your groceries, and your CPA or tax professional sees one file at the end of the year.

If you are managing celiac disease for your child, your parent, or another family member, the picture is different. Whose tax return do the medical expenses go on? Can you use your own HSA to pay for your child's gluten-free groceries? What happens to the expense documentation when a dependent has two households?

These are real questions with real answers. This guide covers the financial side only — tracking, documentation, and the year-end handoff to your CPA or tax professional. It does not cover nutrition, cross-contamination protocols, or school accommodations. Those questions deserve their own guides.

IRS Publication 502 lets you include a dependent's celiac expenses on your Schedule A.

Under IRC §213, you may deduct unreimbursed medical expenses you pay for yourself, your spouse, or a qualifying dependent, to the extent they exceed 7.5% of your AGI. The excess cost of a gluten-free diet for someone with a physician-diagnosed celiac disease is a qualified medical expense under IRS Revenue Ruling 76-80. The deductible portion is the price difference between the GF product and its conventional equivalent — not the full price of the food.

Whether your dependent qualifies depends on IRS rules for qualifying children and qualifying relatives. The dependency tests — residency, support, income — apply the same way here as for any other medical expense. If you share custody, only the parent who claims the dependency exemption can include the child's medical expenses on their return.

The deductible amount is the premium — what GF costs above conventional. Log both prices every trip. Your CPA or tax professional cannot reconstruct that gap from a receipt that just says $7.99.

You can use your own HSA or FSA for a dependent's qualified celiac expenses.

HSA and FSA distributions are tax-free when used for the qualified medical expenses of the account holder, the account holder's spouse, or any dependent. That means your HSA card can pay for your child's celiac-related costs — including, in some interpretations, the gluten-free food cost premium — without triggering tax or penalty.

The GF food cost premium is a contested area for HSA/FSA reimbursement. Some practitioners take the position that the premium qualifies with a letter of medical necessity; others do not. Do not use HSA or FSA funds for GF food purchases without written guidance from your CPA or tax professional first.

For medical expenses that clearly qualify — doctor visits, lab work, prescriptions, and medical mileage — your HSA or FSA can pay directly. Just note that expenses reimbursed by an HSA or FSA cannot also be deducted on Schedule A. Track which expenses were paid how, so your CPA or tax professional can sort them at year end.

Track as if you will need to defend every line. You might.

The IRS does not audit most Schedule A filings, but unusual deductions draw scrutiny. A GF food cost premium deduction for a dependent is unusual. Your documentation needs to show a clear chain from diagnosis to expense to your tax return.

1 Physician's written diagnosis — a note on office letterhead stating the patient has celiac disease and requires a strict gluten-free diet for medical reasons. Get it updated if it is more than two years old.
2 GF vs. conventional price logs — same store, same shopping trip, same size product. Log both. The premium is the line on your Schedule A, not the full GF price.
3 Medical expense receipts — doctor visits, lab work, prescriptions, and insurance premiums paid out of pocket. Note what insurance covered vs. what you paid.
4 Medical mileage log — round-trip miles to every celiac-related appointment. The 2026 IRS medical mileage rate is $0.205 per mile. Confirm the current rate with your CPA or tax professional.
5 HSA/FSA payment notes — flag every expense paid via HSA or FSA. Those cannot double-count on Schedule A. Your CPA or tax professional needs to know which is which.

What your CPA or tax professional actually needs from you in January.

Most CPA or tax professional offices see celiac disease expenses once a year, during tax prep. They do not know this area well. The cleaner and more organized your documentation, the less time they spend on questions you cannot answer in the moment, and the lower the risk of missing something.

A clean year-end handoff includes: a one-page summary of total expenses by category, the underlying logs (grocery premium, mileage, medical), the physician's diagnosis letter, a note on any HSA or FSA reimbursements, and your AGI from the prior year so they can calculate the 7.5% threshold before the meeting.

The Schedule A Prep Worksheet generates exactly that summary. Fill it in before your tax appointment and email it a week early. Your CPA or tax professional will thank you.

Reports ready for your CPA or tax professional to review before filing Schedule A. That is the standard. Not "I think I spent about this much." A log they can check.
