Sales and Use Tax Exemption for Diapers and Feminine Hygiene Products Begins Aug. 28 in Missouri

Missouri families and caregivers will soon save money on essential health items thanks to a new law that takes effect Aug. 28. The Missouri Department of Revenue has announced that beginning that day, sales of child and adult diapers, certain feminine hygiene products and incontinence supplies will be fully exempt from both state and local sales and use taxes. The department’s notice reminds retailers and taxpayers that the exemption applies across the board; these products should no longer be included in taxable sales after Aug. 28 and must be reported as a negative adjustment on sales and use tax returns【261820617722166†screenshot】.

The change stems from legislation passed by the General Assembly earlier this year that adds diapers and qualifying feminine hygiene products to Missouri’s list of tax‑exempt necessities. Lawmakers argued that taxing these items placed an unfair burden on families with small children and people who menstruate or experience incontinence. Under the new law, diapers and pads are treated similarly to other tax‑exempt medical supplies. To qualify, the products must be designed for human use and function primarily as diapers, pads, tampons, sanitary napkins or similar items used to absorb or contain fluids. Wipes, diaper bags and cosmetic products are not included.

Business owners are responsible for ensuring the exemption is applied correctly. The Department of Revenue advises retailers to update their point‑of‑sale systems so that diaper and feminine hygiene sales are excluded from taxable totals. When filing returns, companies must report these sales as deductions rather than including them in gross receipts. Failing to adjust could lead to overcollection of taxes and potential penalties. To help businesses comply, the department has published a frequently asked questions document and examples of eligible products. The guidance explains that adult diapers and incontinence briefs, baby diapers, sanitary napkins, panty liners and tampons all qualify for the exemption, while products marketed primarily for personal grooming do not.

For consumers, the exemption means everyday necessities will cost less at the checkout counter. Families with infants or toddlers can expect savings on every pack of diapers, and individuals who rely on feminine hygiene or incontinence products will also benefit. The department encourages shoppers to check receipts after Aug. 28 to make sure taxes are not mistakenly applied. If tax is charged in error, customers should request a refund from the retailer. Questions about the new law can be directed to the Department of Revenue’s Taxation Division or answered through the department’s official FAQ and email help line.

Missouri’s move follows similar tax policy changes in other states that have removed sales taxes on diapers and menstrual products. Advocates say eliminating these so‑called “period taxes” reduces financial strain for families and helps ensure everyone can afford basic hygiene supplies. The Department of Revenue will continue to update its guidance as implementation of the exemption progresses and encourages both retailers and consumers to stay informed through its official channels.
