Is Gluten-Free Food FSA, HSA & Tax Deductible?

How Gluten-Free Expenses Qualify

The IRS allows people on a medically necessary gluten-free diet (for example for celiac disease) to claim the excess cost of gluten-free foods as a medical expense. This means only the price difference between gluten-free and regular products is eligible, not the full purchase price. You can claim it through an FSA or HSA, or as an itemized tax deduction when your other medical costs already put you over the IRS threshold. Anyone can use GF Savings to track gluten-free spending; the rules below are about getting money back.

                Good News: GF Savings automatically calculates this price difference for you, so your FSA, HSA, or tax claim is simple and accurate.
            

IRS Requirements

The Three-Part Test (Revenue Ruling 55-261)

To qualify for the medical expense deduction, the IRS requires:

Food must alleviate or treat a medical condition requiring a gluten-free diet
The expense is not part of normal nutritional needs
A physician has substantiated the medical necessity

"The amount you can include in medical expenses is limited to the amount by which the cost of the special food exceeds the cost of a normal diet."

Source: IRS Publication 502 (2024)

"The excess cost of specially prepared foods designed to treat a medical condition over the cost of ordinary foods which would have been consumed but for the condition is an expense for medical care."

Source: IRS Information Letter 2011-0035, written by the IRS Office of Chief Counsel in reply to a celiac organization's request for guidance on special foods.

What You Need to Claim

Required Documentation

Documentation from your physician that a gluten-free diet is medically necessary
A Letter of Medical Necessity (LMN) from your doctor stating a gluten-free diet is required. Don't have one yet? GF Savings will help you draft one to send to your physician.
Receipts for your gluten-free purchases
Price comparison documentation (GF Savings provides this)

                Good to know: Most FSA and HSA administrators require the LMN only once and don't ask for renewal. GF Savings will let you store yours so it travels with every report you generate.
            

How We Calculate Your Savings

GF Savings compares each gluten-free purchase to a comparable mainstream regular product at national reference prices, verified quarterly against a major grocer's published shelf prices. Where a store brand exists, you can switch the comparison to it.

Example Calculation

                    Canyon Bakehouse GF Bread (your purchase)
                    $7.49
                
                    Regular Bread (national reference price)
                    $3.00
                
                    Claimable Amount
                    $4.49

Items with No Regular Equivalent

Specialty items that have no gluten-containing counterpart (like xanthan gum or specialty GF flours) may be claimed at their full cost, as they are purchased solely to meet dietary needs.

Our Comparison Methodology

Factor	Our Approach	IRS Requirement
Comparison Source	National reference prices (mainstream brand, verified quarterly)	Not specified
Product Matching	Same category, similar size	"Comparable" product
Price Updates	Weekly refresh	Not specified
Documentation	Detailed reports with methodology	Receipts + calculation schedule

                Note: The IRS does not require same-store price matching. Using consistent, verifiable prices from a major national retailer is an accepted methodology.
            

Official IRS Sources

Our eligibility guidance is based on the following IRS publications and rulings:

Source	Key Provision
Publication 502 (2024)	Medical expense deduction rules for special food
Revenue Ruling 55-261	Three-part test for special food deductibility
Revenue Ruling 76-80	Excess cost calculation methodology
Revenue Ruling 2002-19	Medical expense deductions under Section 213
Information Letter 2011-0035	Excess cost of specially prepared foods for a medical condition is medical care; physician's diagnosis establishes the medical purpose

Additional guidance from: Celiac Disease Foundation, Beyond Celiac, and Gluten Intolerance Group

FSA vs HSA vs Tax Deduction

Method	Threshold	Best For
FSA Reimbursement	No AGI threshold	Pre-tax dollars, immediate reimbursement
HSA Reimbursement	No AGI threshold	Pre-tax dollars, funds roll over
Tax Deduction	Must exceed 7.5% of AGI	Large medical expenses, itemizers only

                No Double-Dipping: Expenses reimbursed through an FSA or HSA cannot also be claimed as a tax deduction.
            

                What the number is worth to you: the amount we show is money you reimburse yourself from pre-tax dollars. If your account would otherwise go unused, it is worth the full amount; if not, it is worth the tax you save on it. Either way it is money you are entitled to and would otherwise leave on the table.
            

                Your administrator's list, and your employer's plan: administrators publish their own eligible-expense lists and letter rules, and they differ. HealthEquity lists special foods as eligible with a letter and pays nothing bought before the letter is approved; FSAFEDS marks gluten-free products not eligible but allows the cost difference on dual-purpose products with a letter; most cap a letter at 12 months. Your employer's plan document has the final say. Tell us who your administrator is and the app shows you their published rules.
