The sales tax rate in Columbia, MO is 7.975 percent on most retail purchases. That figure combines a 4.225 percent Missouri state tax, a 1.75 percent Boone County tax, and a 2.0 percent City of Columbia tax.1City of Columbia. Tax Breakdowns Certain shopping areas add district levies on top, and some categories — groceries, vehicles, cannabis — carry their own rates.
What Makes Up the 7.975 Percent
The state portion of 4.225 percent is authorized under RSMo 144.020, which imposes tax on retail sales of tangible personal property, admissions, utilities, telecommunications, lodging, and rentals.2Missouri Revisor of Statutes. Missouri Revised Statutes Section 144.020 – Rate of Tax Boone County layers 1.75 percent on top, and Columbia adds 2.0 percent to fund municipal services.1City of Columbia. Tax Breakdowns
Districts Where the Rate Goes Higher
Columbia contains more than a dozen Transportation Development Districts (TDDs) and Community Improvement Districts (CIDs) that add their own tax on top of the standard 7.975 percent. The city itself does not collect this money; each district manages its own revenue.1City of Columbia. Tax Breakdowns

- Downtown CID: 0.50 percent
- Business Loop CID: 0.50 percent
- Columbia Mall TDD: 0.50 percent

Groceries Are Taxed Lower
Food that qualifies for the federal food stamp program gets a reduced state rate. RSMo 144.014 cuts the state’s share from 4.225 percent to 1.225 percent on qualifying groceries.3Missouri Revisor of Statutes. Missouri Code 144.014 – Food, Retail Sales Of, Rate of Tax The reduction applies only to the state portion; Boone County and Columbia still collect their full local rates.4Missouri Department of Revenue. Missouri Sales Tax Reduction on Food
Groceries in Columbia end up taxed at roughly 4.975 percent — 1.225 state, 1.75 county, and 2.0 city. Prepared meals and restaurant food don’t qualify and are taxed at the full 7.975 percent.5Legal Information Institute. 12 CSR 10-110.990 – Tax-Sales of Food
Vehicles: You Pay at Titling, Not at the Dealer
Dealers don’t collect sales tax on cars and other titled vehicles. You pay it to the Missouri Department of Revenue when you title and register the vehicle, at the state’s 4.225 percent plus applicable local rates.6Missouri Department of Revenue. Buying a Vehicle For a Columbia resident buying a $25,000 vehicle with no trade-in, the sales tax comes to roughly $1,994.
A trade-in cuts the taxable amount. Tax is calculated on the purchase price minus the trade-in allowance, so an $8,000 trade on a $25,000 car leaves you owing tax on $17,000. If you bought from an out-of-state dealer, bring proof of the trade — usually a copy of the assigned title or a Secure Power of Attorney — to claim the credit.6Missouri Department of Revenue. Buying a Vehicle
You have 30 days from purchase to title the vehicle and pay. Miss it and a $25 penalty starts on day 31, with another $25 added for each additional 30-day period, up to a $200 cap.6Missouri Department of Revenue. Buying a Vehicle
Cannabis
Recreational marijuana carries a 6 percent state excise tax under the Missouri Constitution, with the money going to the Veterans, Health, and Community Reinvestment Fund. That 6 percent sits on top of the regular state and local sales taxes.7Missouri Revisor of Statutes. Missouri Constitution Article XIV Section 2
Columbia voters were asked in April 2023 to approve an additional 3 percent selective sales tax on recreational cannabis. If in force, that brings the combined city tax on recreational purchases to 5 percent — the standard 2 percent plus the 3 percent selective.8City of Columbia. Impact of Recreational Marijuana Tax on the City of Columbia’s Revenue Medical cannabis is taxed at the standard local rate without the excise or selective add-ons.
What’s Exempt
Prescription drugs from a licensed pharmacist, including insulin and medical-grade oxygen, are fully exempt. Prosthetic devices that replace the function of a permanently inoperative body organ are also exempt: cardiac pacemakers, hearing aids, and artificial limbs qualify. Eyeglasses and contact lenses do not.9Missouri Department of Revenue. 12 CSR 10-110.013 Drugs and Medical Equipment
Repair labor is another spot where the rules matter. If a shop separates parts and labor on the invoice, the labor line isn’t taxable. Fabrication labor — creating a new product — is taxable even when listed separately.10Missouri Department of Revenue. Sales Tax Taxability and Exemptions
The August Back-to-School Holiday
Missouri suspends all state and local sales tax for one August weekend on certain school-related items. In 2026, the holiday runs from Friday, August 7, at 12:01 a.m. through Sunday, August 9, at midnight.11Missouri Department of Revenue. Back to School Sales Tax Holiday What qualifies:
- Clothing at $100 or less per item (includes footwear and diapers; jewelry, handbags, and watches don’t count)
- School supplies up to $50 per purchase (notebooks, writing instruments, art supplies, backpacks, and similar)
- Graphing calculators at $150 or less
- Computer software at $350 or less
- Personal computers and peripherals up to $1,500
The limits are per item, not per receipt. A $90 pair of shoes qualifies no matter how full your cart is. But an item that goes over the cap — say, a $120 jacket — is taxed at the full rate on the entire price, not just the amount above the limit.12Missouri Revisor of Statutes. Missouri Revised Statutes Section 144.049 – Sales Tax Holiday
Buying From Out of State
When an out-of-state seller doesn’t charge Missouri sales tax, you owe use tax instead, at the same combined rate. RSMo 144.610 applies this to tangible personal property stored or used in Missouri.13Missouri Revisor of Statutes. Missouri Code 144.610 – Tax Imposed, Property Subject Columbia voters approved a local use tax in April 2022 that matches the city’s 2 percent sales tax, closing the gap that used to give remote sellers a price edge.14City of Columbia. Use Tax
Cross $2,000 in taxable out-of-state purchases during a calendar year and you must file an Individual Consumer’s Use Tax Return (Form 4340) by April 15 of the following year. That $2,000 is a filing threshold, not an exemption: once you’re over, tax is due on every qualifying purchase for the year, not just the piece above $2,000.15Missouri Department of Revenue. Individual Consumer’s Use Tax Most large online retailers already collect the full rate at checkout, so this mainly comes up with smaller vendors or private sellers.
