Are diapers taxed in California? Children’s diapers are not — they are fully exempt from both state and local sales and use tax under Revenue and Taxation Code section 6363.9, which erases the entire combined rate that would otherwise apply at checkout.1California Legislative Information. California Revenue and Taxation Code 6363.9 – Exemptions Adult incontinence products are a different story: they remain fully taxable, and a doctor’s prescription does not change that.
The children’s exemption is permanent, with no expiration or renewal, and it applies the same way whether you buy in a California store or order online from an out-of-state retailer shipping to a California address.2California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6363.9
Which Children’s Products Qualify
The statute covers diapers “designed, manufactured, processed, fabricated, or packaged for use by infants, toddlers, and children.”1California Legislative Information. California Revenue and Taxation Code 6363.9 – Exemptions That takes in both disposable and cloth diapers, and it also takes in training pants and pull-ups sold in the baby aisle, since they are packaged for young children transitioning out of diapers.
What matters is who the product is designed and marketed for, not who is buying it. An adult picking up a package of children’s diapers pays no tax. An adult diaper remains taxable even if the buyer is caring for a child with a medical condition who needs a larger size.
What the Exemption Saves You
California’s statewide base rate is 7.25%, which splits into a 6.00% state portion and a 1.25% local portion for county transportation and city or county operations.3California Department of Tax and Fee Administration. Detailed Description of the Sales and Use Tax Rate Cities, counties, and special districts stack additional voter-approved taxes on top, and in places like Lancaster and Palmdale the combined rate reaches 11.25%.4California Department of Tax and Fee Administration.

Families spending roughly $80 to $150 a month on diapers would otherwise owe somewhere between $6 and $17 a month in sales tax, depending on where they live. Across two or three years of diapering, that is several hundred dollars.
Adult Diapers Are Still Taxed
Adult briefs, pads, and pant-and-pad systems are subject to the full combined sales tax rate everywhere in California. A prescription does not create an exemption. Sales and Use Tax Regulation 1591 specifically excludes incontinence supplies from the definition of tax-exempt “medicines,” listing bandages, pads, supports, and dressings as articles that fall outside the exemption even when a physician orders them.5California Department of Tax and Fee Administration. Regulation 1591 – Medicines and Medical Devices
The broader medical exemption under Revenue and Taxation Code section 6369 is narrower than many people assume. It covers prescription drugs dispensed by a pharmacist, prosthetic devices, orthotic braces, and ostomy appliances required after surgery that creates an artificial body opening.6California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6369 Adult diapers do not fit any of those categories.
Federal Deductions, HSAs, and FSAs
Separate from California sales tax, the federal rules on deducting or reimbursing diaper costs are strict. The IRS does not treat ordinary diapers as a qualified medical expense. Publication 502 says you cannot include diaper costs as a medical expense “unless they are needed to relieve the effects of a particular disease.”7Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses
The same rule governs Health Savings Accounts and Flexible Spending Accounts. Standard diapers for a healthy child are not reimbursable. The narrow exception is where a physician documents that a specific condition, such as a diagnosed disability or chronic illness, requires the use of diapers or specialized incontinence products.
If a Store Charges You Tax Anyway
Retailers are required to stop collecting sales tax on exempt children’s diapers, but point-of-sale systems are not always current. If you see tax on a children’s diaper purchase, ask the store for a refund first. Most will correct the charge on the spot.
If the retailer won’t help, file directly with the California Department of Tax and Fee Administration using Form CDTFA-101 (Claim for Refund or Credit), either online or by mail to the Refunds Section in Sacramento. Your claim needs to explain why the tax was overpaid, state the amount, and include a receipt showing the charge. The deadline is the later of three years from the return’s due date or six months from the date you overpaid.8California Department of Tax and Fee Administration. Filing a Claim for Refund (Publication 117)
Programs That Help With Diaper Costs
Even without sales tax, diapers are expensive, and two California programs help directly. The CalWORKs diaper supplement pays $30 a month for each child under 36 months. To qualify, you must be a CalWORKs participant enrolled in a welfare-to-work plan, and the supplement is paid automatically for each eligible child.9California Legislative Information. AB-1773 CalWORKs – Supportive Services
The California Department of Social Services also runs a Diaper and Wipes Allocation program that distributes supplies through a network of food banks and community organizations around the state.10California Department of Social Services. Subprograms and Information – Diaper and Wipes Allocation You do not have to be a CalWORKs participant to receive supplies through these partners; eligibility generally depends on low income and having an infant or toddler.
CalFresh (California’s SNAP program) and WIC cannot be used to buy diapers, because those benefits are restricted to food and formula.11California Commission on the Status of Women and Girls. AB 798 – Emergency Diaper and Wipe Distribution Program The state distribution program exists to fill that gap.
