Mattresses can be FSA eligible, but only when you buy one primarily to treat or prevent a specific physical or mental illness and a healthcare provider documents that medical need. A mattress bought for general comfort or better sleep does not qualify, and if the mattress is a special form built to accommodate a disability, you may only be reimbursed for the extra cost above the price of an ordinary mattress.1IRS. Medical and Dental Expenses – Section: Personal Use Items
When a Mattress Counts as Medical Care
Federal rules limit medical care to expenses focused on treating or preventing a specific defect or illness. Most mattresses are personal items, so the default answer is no. The purchase moves into medical territory when you intend it to address a diagnosed condition such as chronic back pain, sleep apnea, or severe arthritis.2Legal Information Institute. 26 CFR § 1.213-1 IRS Publication 502 summarizes the controlling authorities that plan administrators apply to this kind of question.3IRS. About Publication 502, Medical and Dental Expenses
Where the mattress is a specialized form built around a disability, the reimbursable amount is the difference between what the specialized mattress costs and what a normal mattress would cost, not the full sticker price.1IRS. Medical and Dental Expenses – Section: Personal Use Items
The Letter of Medical Necessity
You cannot certify your own purchase. An independent third party has to verify that the expense is medical, and if a plan reimburses expenses that were never properly substantiated the IRS may treat those payments as taxable income.4IRS. Internal Revenue Bulletin: 2006-31 – Section: Notice 2006-69 — B. Prohibition Against Self-Certification In practice, plan administrators ask for a letter of medical necessity from a healthcare provider explaining why the mattress is needed to treat the condition rather than for personal comfort. Many benefit administrators post a template on their website so the letter includes everything the plan needs.
You will also need a record from the seller showing the product name, the date of the sale, and the total amount paid.5IRS. Internal Revenue Bulletin: 2006-31 – Section: Notice 2006-69 — III. Additional Use of Cards to Substantiate Health FSA and HRA Medical Expenses Keep both documents together in case the administrator asks for them after the fact.
Submitting the Claim
FSA funds only cover expenses you incur while the plan is covering you. Plans cannot reimburse future or projected purchases in advance. If you pay with an FSA debit card and the transaction does not auto-verify, you will need to send the receipt and the letter of medical necessity to the administrator, usually through an online portal or mobile app.6IRS. Internal Revenue Bulletin: 2006-31 – Section: Notice 2006-69 — II. Background Processing typically takes five to ten business days, depending on the provider.
Because a mattress is a large purchase that looks personal on its face, expect the administrator to ask for documentation even when the card runs through at checkout. Have the letter ready before you buy.
