Missouri Sales and Use Tax: Rules, Rates, and Compliance Guide

Sales and Use Tax Basics in Missouri

Sales Tax

The State of Missouri applies sales tax on retail sales of physical goods and listed services, with all such sales generally considered taxable unless a specific exemption applies. Retailers are liable for collecting sales tax from consumers and remitting sales tax to the Department of Revenue. 

Use Tax

In Missouri, the use tax applies to the storage, use, or consumption of tangible goods. In contrast to sales tax, which is applied to retail sales within the state, use tax is owed directly by persons who use or store the goods if the purchase was not taxed at the point of sale. Notably, a use tax return is required if individuals exceed USD 2,000 in purchases in a year.

Missouri Sales and Use Tax Rates

Missouri has a statewide sales and use tax rate of 4.225%. The state and use tax rate is divided among four state funds that support key public functions. More specifically, 3% goes to General Revenue, 0.125% to Conservation, 1% to Education, and 0.10% to Parks and Soils programs.

In addition to state rates, local rates, including city, county, and district, may also apply, so the total tax collected depends on the combined state and local rates at the seller’s location. State and local taxes are collected and remitted together to the Department of Revenue, which then distributes local taxes to the local governments.

Tax-Exempt Transactions

Sales and use tax legislation includes both tax exemptions and exclusions. Although both remove certain transactions or items from taxation, they operate in different ways. Exemptions, on the one hand, deliberately waive tax on items that would typically be taxed. Thus, they reflect a legislative choice to exclude certain transactions from the scope of sales and use tax. Exclusion, on the other hand, applies to items that fall entirely outside the scope of taxation, meaning these items were never intended to be taxed in the first place.

The Department of Revenue provides a list of exemptions and exclusions provided for agricultural, manufacturing, and industrial sectors.  Furthermore, exemptions are provided for common carriers purchasing motor vehicles and specific pipeline pumping machinery and equipment. Non-profit organizations, government agencies, and public entities may also benefit from exemptions.

Nexus Rules in Missouri

Depending on the taxable person's location, businesses and individuals may become liable for tax purposes if they establish one of the defined nexus or substantial presence in Missouri. There are three prime ways to develop a nexus: by being physically present or by exceeding the economic or marketplace nexus thresholds.

Physical Nexus

Physical nexus or physical presence exists when a taxable person owns or leases real estate property, such as storage or warehouse,  or tangible property in Missouri, or when individuals such as employees, agents, representatives, independent contractors, brokers, or similar actors either live in the state or regularly and systematically enter the state to conduct business on the taxable person's behalf. 

Notably, occasional deliveries into the state by the taxable person’s delivery vehicles with no other contacts do not constitute physical presence to establish a substantial nexus.

Economic Nexus

Even though the Missouri government enacted an economic nexus in 2021, the provision came into effect in 2023. Therefore, since January 1, 2023, remote sellers must register, collect, and remit Missouri sales tax on retail sales of tangible goods if their gross receipts from taxable sales exceed USD 100,000 in a calendar year.

Marketplace Nexus

The marketplace facilitator rules were enacted and came into effect together with the economic nexus rules. Consequently, the same USD 100,000 threshold applies to marketplace facilitators. Therefore, once the threshold is exceeded, marketplace facilitators operating in Missouri must register for, collect, and remit taxes on all taxable sales delivered into the state that occur through their marketplace, whether the sale is made by them directly or by a third-party marketplace seller.

Taxable Goods and Services in Missouri

In addition to imposing sales and use tax on most retail sales of tangible goods, the Missouri legislation also subjects a wide range of services to taxation. Therefore, admissions paid for places of amusement, entertainment, recreation, and athletic events are taxable. 

Additionally, telecommunication services, including both local and long-distance calls, as well as the incidental rental of related equipment, are taxed, except for internet and interactive computer services. Furthermore, Issiouri imposes tax on room rentals, meals, and drinks provided in hotels, restaurants, and similar establishments, and on intrastate transportation tickets sold by carriers such as railroads, airlines, and licensed bus and truck operators.

E-Commerce Framework

Remote sellers who sell tangible goods and do not have a physical presence in the state are responsible for collecting and remitting taxes to the Department of Revenue once they exceed the USD 100,000 threshold in a year.

Marketplace Rules

In addition to selling goods through their own websites, online stores, and similar channels, sellers may also offer goods through a marketplace operated by a marketplace facilitator. The tax obligations for marketplace sellers depend on whether they sell goods or services exclusively through the marketplace, or combine them with sales through their own website or online stores. 

When a sale is conducted solely through a marketplace facilitator, marketplace sellers are not liable for registering, collecting, or remitting taxes. However, when sales are combined and exceed the USD 100,000 threshold, marketplace sellers must register, collect, and remit taxes on sales made outside the marketplace.

Digital Goods and Services

Under the  Missouri sales and use tax rules and regulations, digital services are taxed only when they fall within the definition of taxable telecommunications services. Thus, digital music and digital signature subscription services are not subject to Missouri state sales or use tax because state law explicitly excludes charges for access to interactive computer services from the telecommunications tax. However, taxable persons still need to check whether local taxes under the Video Services Providers Act apply.

Digital Marketplace

Individuals or businesses that help marketplace sellers complete retail sales by listing or advertising taxable goods or services, and by collecting payment from customers and passing it on to the seller, are considered marketplace facilitators. Because they perform these functions, facilitators are treated as sellers for tax purposes. Consequently, marketplace facilitators must comply with all sales and use tax obligations in Missouri.

Notably, the definition excludes businesses that provide only online advertising or product listings without handling customer payments, as well as travel agencies and parts of marketplaces that provide travel-related services, such as booking transportation or lodging. Financial institutions that process payments only on behalf of sellers or facilitators and do not otherwise participate in the sales process are not considered marketplace facilitators.

Digital Platform Operator

Once the marketplace facilitator exceeds the USD 100,000 threshold, it must register for, collect, and remit taxes on all sales made through its platform on behalf of marketplace sellers, regardless of whether those sellers have a retail sales license or would have been required to collect the tax themselves. Moreover, the obligation to collect and remit applies to all sales, including those made by the facilitator directly and by marketplace sellers.

Marketplace facilitators must maintain detailed records of all in-state deliveries, including invoices listing the buyer, address, purchase amount, and tax collected, and make these available to the Tax Authorities upon request. 

Filing and Payment Requirements in Missouri

The filing frequency depends on the amount of due state taxes, excluding local taxes. Therefore, if the monthly due tax amount is USD 500 or more, monthly returns and payments are required. Taxable persons whose due monthly taxes are below USD 500, but above USD 200, may file and pay quarterly. Finally, those with monthly collected taxes up to USD 200 may file and make payments on an annual basis. Notably, tax returns are required even if no sales were made during the tax period.

Penalties for Non-Compliance with Sales and Use Tax Requirements

Late tax return filing or payments trigger both interest and penalties. Interest is calculated based on the total due tax and the number of days the return is outstanding, using either an annual percentage rate, set at 8% for 2025 and 7% for 2026, converted to a daily amount, or the official daily rate directly.

Regarding penalties, a 5% late return penalty is imposed on the tax owed for the first month of delay, with an additional 5% for each subsequent month or fraction thereof, up to a maximum of 25%. Similarly, the 5% penalty is applied to the deficiency unless reasonable cause exists. 

Additionally, if the late payment results from negligence or intentional disregard of the rules, without intent to defraud the state, an additional 5% penalty will be calculated. However, if late filing or payment occurred with the intent to commit fraud or evade, the Tax Authority may assess the tax based on available information and determine the amount owed.
