Clayton, Missouri sales tax is 8.988% on most retail purchases as of January 2026, and 10.488% inside several special taxing districts within the city.1Missouri Department of Revenue. Sales and Use Tax Rate Tables – January 2026 The combined rate stacks Missouri state tax, St. Louis County tax, and City of Clayton tax, and because it depends on the exact street address of the sale, a purchase on one block can be taxed differently than a purchase two blocks away.
What Makes Up the 8.988%
Missouri’s state sales tax contributes 4.225% of the total. That piece is split internally: 3.0% to general revenue, 1.0% to education, 0.125% to conservation, and 0.10% to parks and soils.2Missouri Department of Revenue. Sales/Use Tax The authorizing statute, RSMo 144.020, imposes the tax on retail sales of tangible personal property, restaurant meals, hotel rooms, telecommunications, utilities, and rentals of personal property.3Missouri Revisor of Statutes. Missouri Code 144.020 – Rate of Tax
The remaining 4.763% comes from St. Louis County and City of Clayton levies. County taxes fund general operations along with dedicated purposes like public transit and emergency communications. Clayton’s share includes a general municipal sales tax plus funds earmarked for parks and stormwater. Both the county and city portions are approved by voters, so the combined rate can shift when residents approve a new levy or let an existing one expire.
The Missouri Department of Revenue collects the full amount from retailers and distributes each jurisdiction’s share, so businesses file a single return rather than paying each taxing authority separately.
Special Taxing Districts in Clayton
Five districts in Clayton currently add 1.500% on top of the base rate, bringing the combined tax inside their boundaries to 10.488%: Centene Plaza TDD, Colonial Marketplace CID, Daniele CID, 25 North Central CID, and 7730 Bonhomme CID.1Missouri Department of Revenue. Sales and Use Tax Rate Tables – January 2026 These Community Improvement Districts and Transportation Development Districts are created to finance targeted projects like parking, streetscaping, or security within a defined footprint.
The difference adds up. On a $500 purchase, you’d pay about $44.94 in sales tax at the base rate versus $52.44 inside a special district. Nothing about the shopping experience signals that you’ve crossed a district boundary, so the only reliable way to check is the Missouri Department of Revenue’s online rate map, which returns every tax layer applied to a given street address.4Missouri Department of Revenue.

What Gets Taxed and What Doesn’t
Most things you’d buy in a store carry the full combined rate: clothing, electronics, furniture, restaurant meals, hotel rooms, utility bills, telecommunications, and rentals of personal property.3Missouri Revisor of Statutes. Missouri Code 144.020 – Rate of Tax
Groceries get a break. Missouri reduces the state tax on qualifying food to 1.225%, waiving the general revenue portion while keeping the education, conservation, and parks components.5Missouri Revisor of Statutes. Missouri Code 144.014 – Food, Retail Sales Of, Rate of Tax County and city taxes still apply in full, so the combined grocery rate in Clayton is lower than the standard rate but not zero. “Qualifying food” generally tracks what SNAP benefits can buy, so prepared restaurant meals are excluded.
Professional services like legal advice, accounting, and medical care fall outside the state’s sales tax base, because Missouri taxes specific transaction categories listed in the statute and most services aren’t on that list.3Missouri Revisor of Statutes. Missouri Code 144.020 – Rate of Tax Missouri also maintains specific exemptions for prescription drugs, certain medical equipment, and agricultural supplies, among others.6Missouri Department of Revenue.

Buying a Vehicle: A Different Rule
Cars, trucks, boats, and trailers don’t follow point-of-sale taxation. Instead, you pay the rate in effect at your home address when you apply for a title.7Cornell Law School. 12 CSR 10-103.350 – Sales Tax on Motor Vehicles A Clayton resident who buys a vehicle in a lower-tax county still owes Clayton’s rate, and the Department of Revenue collects it at title application, not the dealer at the point of sale. Shopping across county lines to save on tax doesn’t work.
Online and Out-of-State Purchases
If you buy something from an out-of-state seller that doesn’t collect Missouri sales tax, whether online, by phone, or while traveling, you owe Missouri use tax at the rate for the address where you receive the goods. For Clayton residents, that’s 8.988%, or 10.488% if delivery is to an address inside a special district.
Missouri requires individuals with more than $2,000 in untaxed taxable purchases during a calendar year to file an Individual Consumer’s Use Tax Return. Once you cross that threshold, you owe tax on every qualifying purchase for the year, not just the amount over $2,000. The return is due by April 15 of the following year.8Missouri Department of Revenue. Individual Consumer’s Use Tax Most major online retailers now collect Missouri sales tax at checkout, so this mainly comes up with smaller out-of-state vendors, catalog orders, and goods bought while traveling.
The August Sales Tax Holiday
Missouri suspends state and local sales tax for one weekend each August. In 2026, the holiday runs Friday, August 7 through Sunday, August 9. The exemption covers specific items within price caps:9Missouri Revisor of Statutes. Missouri Code 144.049 – Sales Tax Holiday
- Clothing priced at $100 or less per item (watches, jewelry, and handbags don’t count)
- School supplies priced at $50 or less per item, including notebooks, pens, art supplies, and backpacks
- Computer software priced at $350 or less
- Personal computers and peripherals priced at $1,500 or less, including desktops, laptops, printers, scanners, mice, and memory
- Graphing calculators priced at $150 or less
Items priced above the cap don’t qualify at all. A $120 shirt doesn’t get the first $100 tax-free; it’s fully taxed.
Checking the Rate at a Specific Address
Because the rate shifts at district lines, the only way to know what you’ll actually pay at a given storefront or delivery address is to look it up. The Missouri Department of Revenue’s interactive rate map returns the full breakdown for any street address in the state.4Missouri Department of Revenue. Sales and Use Tax Rate Map The Department also publishes quarterly rate tables that list every jurisdiction and its associated rate.1Missouri Department of Revenue. Sales and Use Tax Rate Tables – January 2026 Both are worth checking before a large purchase or when a receipt shows a rate that doesn’t match what you expected.
