Do You Have Nexus in Missouri?

Before diving into the details of Missouri sales tax regulations, it's crucial to determine whether your business has nexus in the state. Nexus is a connection or presence that obligates a business to collect and remit sales tax. In this section, we'll explore various types of nexus and how they apply to Missouri.


What Creates Sales Tax Nexus in Missouri? 

In Missouri, several factors can create sales tax nexus for your business, including physical presence, economic activity, affiliate relationships, click-through referrals, and marketplace facilitation.

Understanding each type of nexus will help you determine if your business is subject to Missouri sales tax requirements.


What creates physical nexus in the state of Missouri?

Physical nexus is established when a business has a tangible presence in Missouri.

This can include:

  • Owning or leasing property, such as an office, warehouse, or storefront

  • Having employees working in the state

  • Maintaining inventory in a Missouri warehouse, even if it's owned by a third party

  • Attending trade shows or conducting in-person sales in the state


What creates economic nexus in the state of Missouri?

Economic nexus is established when a business reaches a certain level of economic activity within Missouri, even without a physical presence. As of January 1, 2023, Missouri implemented economic nexus rules, requiring remote sellers to collect and remit sales tax if they have:

  • More than $100,000 in gross receipts from sales of tangible personal property delivered into Missouri during the previous or current calendar year


What creates affiliate nexus in the state of Missouri?

Affiliate nexus is established when a business has a relationship with an in-state company or individual that helps promote or facilitate sales.

This can include:

  • Engaging in a contract with an in-state affiliate to refer customers in exchange for a commission

  • Using an in-state company to provide services such as repairs, maintenance, or delivery


What creates click-through nexus in the state of Missouri?

Click-through nexus is not explicitly addressed in Missouri sales tax laws. However, if your business has a strong enough affiliate relationship with an in-state company, it may create affiliate nexus, as discussed earlier.


What creates marketplace nexus in the state of Missouri?

Marketplace nexus is established when a marketplace facilitator (e.g., Amazon, eBay, or Etsy) makes sales on behalf of third-party sellers. As of January 1, 2023, Missouri requires marketplace facilitators to collect and remit sales tax on behalf of their sellers if their gross sales into Missouri exceed $100,000 in a calendar year.


Does Missouri have use tax laws?

Yes, Missouri has a use tax, which applies to the storage, use, or consumption of tangible personal property in the state when sales tax has not been paid. Use tax rates are the same as sales tax rates and are determined by the buyer's location. Businesses with nexus in Missouri are responsible for collecting and remitting use tax on sales made to Missouri customers if sales tax has not already been collected. 



Missouri Sales Tax Registration

Before you can start collecting sales tax in Missouri, you'll need to register for a sales tax license. In this section, we'll guide you through the registration process and answer some common questions about obtaining a Missouri sales tax license.


How to Register for Sales Tax in Missouri

To register for a sales tax license in Missouri, follow these steps:

  1. Determine if you have nexus in Missouri: As we discussed earlier, you need to have a connection or presence in the state that obligates you to collect and remit sales tax. Review the various types of nexus to determine if your business meets any of the criteria.

  2. Gather necessary information: Before you begin the registration process, gather all required information, including your federal Employer Identification Number (EIN), business structure, legal and trade names, physical and mailing addresses, and the names and Social Security numbers of all business owners or responsible parties.

  3. Register online: Visit the Missouri Department of Revenue's website and access the Missouri Tax Registration Application. Complete the application by providing the requested information about your business and its activities in Missouri. Submit the application once all required fields are completed.

  4. Receive your Missouri sales tax license: After submitting your application, the Missouri Department of Revenue will review it and, if approved, issue you a sales tax license. This license allows you to collect and remit sales tax on your sales to Missouri customers. You'll need to display the license prominently at your place of business.

  5. Set up sales tax collection: Once you have your sales tax license, set up your point-of-sale system, accounting software, or e-commerce platform to collect the appropriate sales tax rates for each Missouri transaction.

By following these steps, you'll be well on your way to becoming sales tax compliant in Missouri.


How Much Does it Cost to Register for a Missouri Sales Tax License?

Good news! Registering for a Missouri sales tax license is free. The Missouri Department of Revenue does not charge a fee for issuing a sales tax license.


Do I Need a Federal Tax ID Number or EIN to Register for a Missouri Sales Tax License?

Yes, you'll need a Federal Tax ID Number, also known as an Employer Identification Number (EIN), to register for a Missouri sales tax license. The EIN is used to identify your business for tax purposes. If you don't have an EIN, you can obtain one from the Internal Revenue Service (IRS) by completing an online application.


Which Agencies in Missouri Might I Need to Register With Additionally?

Depending on your business activities, you may need to register with other agencies in Missouri. Some common additional registrations include:

  • Missouri Secretary of State: If your business is a corporation, limited liability company (LLC), or other formal business structure, you'll need to register with the Missouri Secretary of State.

  • Missouri Department of Labor and Industrial Relations: If you have employees, you may need to register with the Missouri Department of Labor and Industrial Relations for unemployment insurance, workers' compensation, and other labor-related requirements.

  • Missouri Division of Alcohol and Tobacco Control: If your business sells alcohol or tobacco products, you may need to obtain additional licenses from the Missouri Division of Alcohol and Tobacco Control.

Be sure to research all relevant agencies and requirements for your specific business to ensure full compliance with Missouri laws and regulations.



Collecting Sales Tax in Missouri

Now that you've registered for a sales tax license, it's time to dive into the details of collecting sales tax in Missouri. In this section, we'll discuss whether Missouri is an origin or destination sales tax state, the types of sales subject to tax, exemptions, and how to handle tax-exempt customers.


Is Missouri an Origin or Destination Sales Tax State?

Missouri is a destination-based sales tax state. This means that sales tax rates are determined by the location of the buyer, not the seller. When selling to Missouri customers, you'll need to collect sales tax based on the rate applicable at the customer's address, which includes state, county, city, and special district taxes.


What Sales are Subject to Sales Tax in Missouri?

In Missouri, sales tax applies to the sale of tangible personal property and certain services. Taxable sales include, but are not limited to:

  • Tangible goods such as furniture, clothing, electronics, and household items

  • Rental or lease of tangible personal property

  • Installation, repair, or maintenance services for tangible personal property

  • Telecommunication services

  • Admission fees for places of amusement, entertainment, or recreation


Is Software as a Service (SaaS) taxed in Missouri?

No, SaaS is not currently taxable in Missouri. The Missouri Department of Revenue defines SaaS as "a software licensing arrangement under which a customer subscribes to access a software application hosted by a vendor." Because SaaS is not delivered in a tangible medium, it is not considered taxable.


What is Exempt from Missouri Sales Tax?

Missouri offers several sales tax exemptions for specific items, organizations, or situations. Some common exemptions include:

  • Sales to government entities

  • Sales to nonprofit organizations

  • Sales of prescription drugs and medical devices

  • Sales of grocery items

  • Sales of educational materials to schools


Who is Eligible for Missouri Sales Tax Exemptions?

Organizations and individuals that qualify for sales tax exemptions in Missouri include:

  • Government entities (federal, state, and local)

  • Nonprofit organizations with a tax-exempt status under Section 501(c)(3) of the Internal Revenue Code

  • Schools, colleges, and universities

  • Hospitals and healthcare facilities

  • Religious organizations


What Should I Do If My Customer is Exempt from Sales Tax in Missouri?

If your customer is exempt from sales tax in Missouri, you'll need to obtain a valid exemption certificate from them. The Missouri Department of Revenue provides a Form 149: Sales and Use Tax Exemption Certificate that exempt organizations or individuals can complete and provide to you.

Keep a copy of the exemption certificate in your records, as you'll need it to support the exempt sale if you're ever audited by the Missouri Department of Revenue.


What Happens If I Lose a Missouri Sales Tax Exemption Certificate?

If you lose a Missouri sales tax exemption certificate, it's important to request a new copy from your exempt customer as soon as possible. If you cannot obtain a new copy, you may be held liable for any uncollected sales tax during an audit.

To avoid this situation, maintain organized records of all exemption certificates and consider using a digital filing system to minimize the risk of loss or damage.



Filing and Paying Sales Taxes in Missouri

Once you've collected sales tax from your Missouri customers, it's time to file and pay those taxes to the state.

  • Interest: Interest is charged on the unpaid tax and any penalties, accruing from the due date until the tax is paid in full. The interest rate is set annually by the state.


Does Missouri offer any sales tax incentives?

Missouri offers several sales tax incentives to encourage business development and investment. Some common incentives include:

  • Enterprise Zone Program: This program offers a variety of tax credits and exemptions for businesses located within designated economically distressed areas.

  • Enhanced Enterprise Zone Program: This program provides state and local sales tax exemptions for eligible businesses that create jobs and invest in designated areas.
