Missouri sales tax on invoices (2026 guide)

Missouri's state sales tax rate is 4.225% — on paper one of the lower state rates. But cities, counties and special districts across Missouri add their own sales taxes, so the combined rate on your invoice is often much higher than 4.225%. Getting the local rate right is the main job when you invoice in Missouri.

The good news for most service businesses: Missouri taxes only the services listed in its sales tax law, and most professional and trade services aren't on the list. Goods are taxable unless an exemption applies, so if you sell parts or products along with your work, you'll still need to charge tax on them.

Missouri sales tax rates

The 4.225% state rate is made up of four parts: general revenue (3%), education (1%), conservation (0.125%) and parks and soils (0.1%). You charge it as one rate.

Local taxes add up

On top of the state rate, cities, counties and certain districts can impose local sales taxes. The Department of Revenue says the amount you collect depends on the combined state and local rate at the seller's location, so when you register you need to know whether your business is inside a city's limits or a special district. The Department publishes a rate lookup on its website for local and combined rates. Once you have the combined rate, our sales tax calculator does the math.

Which services are taxable in Missouri?

All sales of tangible personal property are taxable unless a specific law exempts them. Services are taxable only if they're listed in Section 144.020 of the Missouri statutes. The Department's list of taxable services includes:

• admissions and seating at places of amusement, entertainment or recreation, games and athletic events,
• utilities — electricity, water and gas (with an exemption for domestic use),
• telecommunications services, including rental of equipment incidental to the service (internet access isn't included), and
• rooms, meals and drinks at hotels, motels, restaurants and other places that regularly serve the public.

Labor charges

Labor is where invoices often go wrong. According to the Department:

• Repair labor is not taxable if it's separately stated on the invoice.
• Fabrication or production labor — making something — is taxable, even when separately stated.

So a handyman or repair shop should always list parts and repair labor on separate lines. Parts are taxable; separately stated repair labor isn't.

Registering to collect Missouri sales tax

You need a Missouri retail sales license before you make retail sales. You can register online or with Form 2643, Missouri Tax Registration Application. Since August 28, 2018, most businesses no longer have to post a bond to collect sales or vendor's use tax, although the Department may require one if a business is delinquent.

Remote sellers. Since January 1, 2023, a remote seller must collect Missouri vendor's use tax once its gross receipts from taxable sales delivered into Missouri exceed $100,000. Check at the end of each calendar quarter whether your sales over the preceding 12 months passed $100,000; if they did, you must start collecting no later than three months after that quarter ends.

What a Missouri sales tax invoice should show

• your business name and address,
• the customer's name and address,
• a unique invoice number and the invoice date,
• a description and price for each item or service,
• repair labor on its own line, separate from parts,
• sales tax as a separate line, with the combined state and local rate, and
• the total due.

In Invoice Native, tick Tax only on the taxable lines — parts and products, not separately stated repair labor.

Resale and exemption certificates

A business buying goods to resell, or a buyer claiming another exemption, gives you Form 149, Sales and Use Tax Exemption Certificate. Keep it on file as evidence for every tax-free sale, and the Department recommends updating resale certificates every five years.

If you accept a certificate in good faith, you aren't required to collect tax on the sale it covers — and if it turns out to be invalid, the purchaser is liable for the tax. Good faith means taking care that what you sell is actually exempt. See how to invoice a tax-exempt customer.

A worked example

Suppose you repair appliances and your shop is in a Missouri city with a combined rate of 8.5% (a hypothetical rate for this example). You fix a customer's washing machine and invoice:

• $120 for replacement parts (taxable), and
• $180 for repair labor, listed separately (not taxable).

Only the parts are taxable: $120 × 8.5% = $10.20. The invoice total is $120 + $180 + $10.20 = $310.20.

If you'd billed a single $300 "repair" without separating the labor, you'd risk tax on the whole amount.

Selling to customers in other states

If you ship goods or deliver taxable services to customers in another state, that state's rules may apply instead of Missouri's. Since the Supreme Court's 2018 decision in South Dakota v. Wayfair, states can require out-of-state sellers to register and collect their sales tax once sales into the state pass a threshold the state sets. If you sell across state lines regularly, check the thresholds and registration rules of each state you sell into — and use that state's rate on those invoices.

Common mistakes on Missouri invoices

• Charging only the 4.225% state rate and forgetting city, county and district taxes.
• Using the wrong local rate because you didn't check whether you're inside city limits or a special district.
• Lumping parts and repair labor together on one line.
• Not taxing fabrication labor, which is taxable even when separately stated.
• Keeping old Form 149s forever. Update resale certificates every five years.
