Whether you own a quilt shop in Kansas City or a restaurant in Chillicothe, dealing with Missouri sales tax can feel like navigating a complex maze. For businesses operating in Missouri, the state rate isn’t the only thing you need to worry about. The patchwork of local rates can dramatically change your tax liability from one city to the next.
Use this guide to break down everything you need to know about Missouri sales tax, from calculating the right rate to filing your returns, helping you stay compliant and avoid costly penalties.
What is the Missouri sales tax?
Missouri imposes a 4.225% state sales tax on the retail sale of tangible personal property and certain taxable services. However, this is just the foundation. The real complexity comes from the fact that counties, cities, and special districts add their own local sales taxes on top of the state rate.
Because the combined rate is determined by the specific location of your sale, the total tax rate your business collects can range from the state minimum to over 10% in some areas.
| Location | State Rate | Estimated Local Rate | Estimated Combined Rate |
| State of Missouri (base) | 4.225% | 0.000% | 4.2225% |
| Kansas City, MO | 4.225% | ~4.77% | ~8.995% |
| St. Louis, MO | 4.225% | ~4.55% | ~8.775% |
Note: Local rates frequently change. Always verify the current, specific rate for your business address using the official Missouri Department of Revenue’s (DOR) rate lookup tools.
How to calculate Missouri sales tax?
To calculate Missouri sales tax, you need to identify the specific combined rate for your transaction’s location.
Purchase Price × (State Rate + Local Rate) = Sales Tax
For example, if you sell a $50 taxable item in an area of St. Louis with an 8.775% combined rate:
$50.00 × 0.08775 = $4.39 in Sales Tax
The total amount charged to the customer would be $54.39.
Use our reverse sales tax calculator
A reverse sales tax calculator can be a handy tool for Missouri businesses, especially restaurants, cafés, food trucks, and retailers, who want to list all-in-one prices that already include tax.
To ensure your Point of Sale (POS) system collects the correct rate when displaying all-inclusive pricing, you can use our sales tax calculator. It helps you break down an all-in price to identify the pre-tax amount.
What is subject to sales tax in Missouri?
In Missouri, the general rule is that the retail sale of tangible personal property is subject to sales tax. That means most businesses are required to collect sales tax on the items they sell. Tangible personal property includes physical goods like clothing, furniture, eyeglasses, and electronics, unless a specific exemption applies.
Does Missouri charge sales tax on services?
Generally, no. Missouri does not tax most professional or personal services (like legal advice, haircutting, or typical repair labor) because the state is focused on taxing tangible goods.
However, there are important exceptions to this rule:
- Services Resulting in a Tangible Good: Labor used to fabricate, create, or produce a product that will be sold at retail is taxable.
- Utilities and Telecommunications: The sale of water, gas, electricity, and local/long-distance telecommunication services for commercial use is generally taxable. Domestic use may be exempt.
- Admission and Entertainment: Fees for admission, seating, and recreation (such as movie tickets or gym memberships) are taxable.
- Prepared Food and Drink: Sales of meals, rooms, and drinks furnished by restaurants, hotels, taverns, or eating houses are taxable.
Visit the Missouri Department of Revenue’s website for a current list of taxable services.
Missouri sales tax on food
Missouri has a split tax rate for food, which is a major compliance point for all food sellers, especially restaurant and grocery store owners:
| Category | State Sales Tax Rate | Local Sales Tax Rate | Application |
| Qualifying Food/Groceries | 1.225% (Reduced Rate) | Applicable | Food for home consumption, seeds, and plants (items eligible for the Federal Food Stamp Program). |
| Prepared Food/ Meals | 4.225% (Full Rate) | Applicable | Food prepared for immediate consumption, or sold by an establishment where over 80% of gross receipts are from prepared food (i.e., most restaurants). |
For restaurant owners: Because most restaurants meet the “over 80% of gross receipts from prepared food” criteria, you are typically required to charge the full combined state and local sales tax rate on all your food and drink sales, regardless of whether the item is hot, cold, or consumed on- or off-premises.
That’s where DAVO by Avalara can help. For restaurants and grocery stores collecting sales tax on food and beverage sales, DAVO automatically sets aside the amount of sales tax you collect each day and manages the filing and payment on your behalf. Instead of figuring out how much to reserve or worrying about deadlines, you can rely on DAVO to file and pay the correct amount on time, helping you stay organized and compliant while you focus on running your business.
What is exempt from sales tax in Missouri?
Specific items and purchasers are exempt from Missouri sales tax, though you must secure the proper documentation to prove the exemption.
Exempt Items (Partial or Full)
- Groceries: Taxed at the reduced state rate of 1.225% (as noted above).
- Prescription Medicine: Fully exempt.
- Manufacturing Inputs: Machinery, equipment, materials, and chemicals used directly in manufacturing, processing, or producing a product for sale are exempt from both state and local taxes.
- Agricultural Items: Feed, seeds, and fertilizer used in the production of crops or livestock for final sale.
- Items Purchased for Resale: Goods purchased by a business that will be resold to a customer are exempt, provided the seller is given a valid resale certificate, Form 149.
How to manage tax-exempt sales in Missouri?
For any exempt sale, you must have a valid document to prove the transaction qualified for a tax break. This documentation could be:
- A Resale Exemption Certificate: For a wholesaler or retailer buying goods they intend to resell.
- A Tax Exemption Letter/ID: Issued by the DOR to qualified nonprofit organizations (e.g., charitable, educational, or religious institutions) or governmental entities, Form 1746.
Retain copies of these forms for your records, as you will be responsible for the uncollected tax if you are audited and cannot prove a sale was exempt.
Missouri sales tax holiday
Missouri offers at least two annual sales tax holidays, providing a temporary exemption from state and local sales taxes on specific items.
- Back-to-School Sales Tax Holiday: This annual holiday begins on the first Friday in August and lasts for three days. It exempts most state and local sales/use taxes on:
- Clothing: Any article with a taxable value of $100 or less.
- School Supplies: Not to exceed $50 per purchase.
- Personal Computers/Peripherals: Not to exceed $1,500 per sale.
- Computer Software: Taxable value of $350 or less.
- Show Me Green Sales Tax Holiday: This exempts state sales tax on purchases of qualifying ENERGY STAR certified new appliances up to $1,500 per purchase. Typically, during a seven-day period starting April 19 and ending April 25, the date for this holiday can vary, so always confirm with the Missouri DOR by visiting their Show Me Green Sales Tax Holiday guide.
- The Show Me Green sales tax holiday applies to purchases for both business and personal use.
Retailers are required to participate during these sales tax holidays. As a business, you’ll want to make sure you are set up to only collect sales tax when applicable.

How to register for a Missouri sales tax license?
Any business selling taxable goods or services in Missouri must register with the DOR to obtain a Sales Tax License (or a Vendor’s Use Tax License for remote sellers). To register, you will need to:
- Apply Online: The quickest way is through the Online New Business Registration portal by completing the online version of Form 2643, Missouri Tax Registration Application.
- Provide Information: You will need your Federal Employer Identification Number (FEIN), physical business address, owner/officer information (including SSNs), and estimated monthly sales (to determine your filing frequency).
- Post a Bond: Most new sellers must post a bond or collateral (like a surety bond or cash deposit) equal to three times their average estimated monthly tax liability. This bond is generally refundable after two years of compliant filing.
How to file Missouri sales tax?
Missouri encourages businesses to file and pay sales tax electronically, and in many cases, it’s required. Filing is done through the MyTax Missouri portal, which allows businesses to submit returns, make payments, and manage their sales and use tax accounts online. You must file electronically if either of the following applies:
- You’re required to file quarter-monthly sales tax
- You report sales or use tax from three or more business locations
Your filing frequency is determined by the amount of state tax (4% for regular locations and 1% for food locations) due. Returns must be filed even if you have zero taxable sales for the period.
Your assigned filing frequency will be:
- Annual: If state tax liability is less than $200 per quarter.
- Quarterly: If state tax liability is $500 or less per month.
- Monthly: If state tax liability is $500 or more per month.
For quarter-monthly filers, you are assigned this schedule by the Missouri Department of Revenue based on tax liability and must submit payments electronically throughout the month. Businesses required to file quarter-monthly, the month is divided into four reporting periods:
- The 1st through the 7th
- The 8th through the 15th
- The 16th through the 22nd
- The 23rd through the end of the month
Businesses that qualify and prefer to file by mail must complete Form 53-1 and send it to:
Taxation Division
P.O. Box 840
Jefferson City, MO 65105-0840
Paper filing can delay processing, which may impact posting and payment confirmation. For this reason, Missouri recommends online filing even for businesses that aren’t required to do so.
How to pay Missouri sales tax?
Missouri encourages, and in many cases requires, businesses to pay sales tax electronically, especially for quarter-monthly filers. Payments can be made via:
E-Check (Electronic Bank Draft)
Paying by electronic bank draft allows the Missouri Department of Revenue to withdraw funds directly from your checking or savings account.
To use this option, you’ll need your bank routing number and account number. A $0.50 handling fee applies to each e-check payment. Payments are considered postmarked on the date you submit them, unless you schedule the payment for a future date. Once submitted, allow three to four business days for the payment to post to your tax account.
Before using this method, confirm that your bank allows ACH withdrawals. Rejected or returned payments may result in additional fees from both the state’s payment processor and your bank.
Credit/Debit Card
Missouri also accepts Visa, MasterCard, Discover, and American Express. Debit cards are processed as credit card transactions. Payments made by card are postmarked on the date they’re submitted, but may take five to six business days to post to your account.
A convenience fee of 2.0% plus $0.25 per transaction applies, regardless of the payment amount. This fee is charged by the state’s third-party payment processor, NCR Corporation, not the Missouri Department of Revenue.
Take the burden of paying Missouri sales tax off your plate with DAVO. By easily integrating it with your POS system, it automatically sets aside the sales tax you collect. Then it files and pays your Missouri sales tax for you so you don’t have to worry about deadlines, penalties, or manual payments.
Missouri sales tax due dates
The return due dates vary based on your assigned frequency.
| Filing Frequency | Due Date |
| Monthly | On or before the last day of the following month (e.g., February sales are due March 31) |
| Quarterly | On or before the last day of the month following the end of the quarter (e.g., Q1/Jan-Mar is due April 30) |
| Annual | On or before January 31 of the following year |
If the due date falls on a weekend or state holiday, the due date is moved to the next business day. For the most up-to-date sales tax due dates, visit Missouri’s Department of Revenue website.
Missouri sales tax discount
Missouri grants a 2% timely payment allowance as long as your sales tax return is postmarked before the due date. With DAVO, this collection allowance is returned to the business in full, sometimes covering the full subscription cost to DAVO.
What is the Missouri sales tax late payment penalty?
Failure to file or pay your Missouri sales tax by the deadline can result in significant penalties and interest:
- Failure to Pay (Return Filed on Time): A 5% penalty is assessed on the tax due. This penalty does not increase.
- Failure to File (No Return Filed): A penalty of 5% for each month the return is late, up to a maximum of 25% of the tax due.
- Interest: Interest is charged on the unpaid balance at an annual rate set by the DOR.
The DOR also has an Additions to Tax and Interest Calculator to estimate the total delinquent liability.
Failure to pay Missouri sales tax can lead to serious consequences. Unpaid taxes may be referred to a collection agency or to a local Prosecuting Attorney for enforcement. In addition to recovering the tax owed, Missouri law allows for a civil penalty of up to 100% of the unpaid tax and criminal prosecution in cases involving willful attempts to evade tax.
The state may also revoke your sales tax license, which would require you to stop making taxable sales in Missouri until the issue is resolved and your account is brought back into good standing. For more information on enforcement and collection procedures, visit the Missouri Department of Revenue’s website.
