When a celiac diagnosis lands, the paperwork that follows is easy to overlook. There are dietary changes to make, appointments to schedule, and a lot of new information to absorb. Documentation tends to feel like a secondary concern, something to deal with later.
The problem is that "later" often means records are harder to reconstruct. Lab results get archived. Receipts get thrown out. The exact date of diagnosis becomes fuzzy. Starting a documentation habit now, even if your diagnosis was months ago, means you will have an organized record when you need one, whether that is for a new specialist, an insurance appeal, or your own reference.
There are two reasons to keep records, and they overlap without being the same. The first is personal: tracking your own health history and your dietary costs, and having documentation ready if your care team changes. The second is for taxes, specifically IRS Schedule A, which lets people with celiac disease count the excess cost of gluten-free food, the difference over the conventional equivalent, toward their medical expenses under certain conditions. Tax records need specific detail (cost comparisons, receipts, a physician's letter confirming medical necessity); personal health records are broader and less formal.
"From day one" means the date a physician confirmed celiac disease. If that date has passed and you have not started tracking, today is the right day to begin. You will not be able to reconstruct everything, and that is fine. A partial record started now beats a complete record started never. If you have already lost early receipts, note the gap, document what you have, and move forward.
Friendly reminder. This checklist is general educational information, not personalized medical, tax, or legal advice. It helps you organize your records; it does not decide what is claimable on your return. The gluten-free excess cost is recognized only for household members formally diagnosed with celiac disease, and the total medical expense figure is subject to income-based thresholds that change by year. Expenses reimbursed through an HSA or FSA cannot also count toward the same medical total. Review your records, and what they add up to, with your CPA or tax professional before filing.
