Children’s diapers are not taxed in California. The state fully exempts diapers designed for infants, toddlers, and children from sales and use tax, so you pay no state tax, no local tax, and no district tax on qualifying products. Adult diapers and incontinence supplies are a different story: they remain fully taxable at the combined rate wherever you buy them.
Which Diapers Are Exempt
The exemption in Revenue and Taxation Code section 6363.9 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 Disposable and cloth diapers both qualify. Training pants and pull-ups sold in the baby aisle qualify too, because they are designed and packaged for young children moving out of traditional diapers.
What matters is the product’s intended user, not the buyer. An adult who buys children’s diapers pays no tax. An adult diaper stays taxable even when the buyer is caring for a child who needs a larger size, because the packaging and marketing target adults.
The exemption applies in stores and online. The statute reaches both “sale in this state” and “storage, use, or other consumption in this state,” so purchases shipped to a California address from an out-of-state retailer are also exempt.2California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6363.9 The rule is permanent. There is no expiration date and nothing to renew.
Adult Diapers and Incontinence Products Are Taxable
Adult incontinence products, including briefs, pads, and pant-and-pad systems, are subject to the full combined sales tax rate. A prescription does not change that. California Sales and Use Tax Regulation 1591 specifically excludes incontinence supplies from the definition of tax-exempt “medicines,” listing bandages, pads, supports, dressings, and similar articles as items that fall outside the exemption even when purchased on a physician’s order.3California Department of Tax and Fee Administration. Regulation 1591 – Medicines and Medical Devices
The broader medical-supply exemption under Revenue and Taxation Code section 6369 is narrower than most people expect. It primarily covers prescription drugs dispensed by a pharmacist, prosthetic devices, orthotic braces, and ostomy appliances required after surgery that creates an artificial body opening.4California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6369 Adult diapers do not fit any of those categories, so the tax applies regardless of medical necessity.
What the Exemption Actually Saves You
California’s statewide base rate is 7.25%, split between a 6.00% state portion and a 1.25% local portion for county transportation and city or county operations.5California Department of Tax and Fee Administration. Detailed Description of the Sales and Use Tax Rate Cities, counties, and special districts add voter-approved taxes on top. Combined rates run well above the base almost everywhere, and cities including Lancaster and Palmdale reach 11.25%.6California Department of Tax and Fee Administration.

A family spending roughly $80 to $150 a month on diapers would otherwise owe somewhere between $6 and $17 in monthly sales tax, depending on where they live. Across two or three years of diapering, the exemption is worth several hundred dollars.
If a Store Charges You Tax on Children’s Diapers
Retailers should not be collecting sales tax on exempt children’s diapers, but point-of-sale systems can be miscoded. If tax shows up on your receipt, ask the store for a refund first. Most will correct it on the spot.
If the retailer won’t refund the tax, you can claim it directly from the California Department of Tax and Fee Administration using Form CDTFA-101, Claim for Refund or Credit. File online through the CDTFA’s site or mail it to the Refunds Section in Sacramento. Your claim needs to explain why the tax was overpaid, state the amount, and include supporting documentation such as a receipt showing the tax charge. The filing deadline is the later of three years from the return’s due date or six months from the date you overpaid.7California Department of Tax and Fee Administration.

Help Paying for Diapers
The tax break helps, but diapers are still expensive. California runs two programs aimed at diaper costs for low-income families.
The CalWORKs diaper supplement pays $30 per month for each child under 36 months. You have to be a CalWORKs participant enrolled in a welfare-to-work plan. The supplement is paid automatically for each eligible child and is meant specifically for diapers.8California Legislative Information. AB-1773 CalWORKs – Supportive Services
The state also funds a Diaper and Wipes Allocation program through the California Department of Social Services, which distributes supplies through designated food banks and community organizations, including the Los Angeles Regional Food Bank and Sacramento Food Bank and Family Services, along with about a dozen other regional partners.9California Department of Social Services. Subprograms and Information – Diaper and Wipes Allocation You don’t have to be on CalWORKs to get supplies through these partners; eligibility usually turns on low income and having an infant or toddler in the home.
One boundary worth knowing: CalFresh (California’s SNAP program) and WIC cannot be used to buy diapers. Those benefits are limited to food and formula.10California Commission on the Status of Women and Girls. AB 798 – Emergency Diaper and Wipe Distribution Program The state-funded distribution program exists to fill that gap.
