Do you need to collect sales tax in Missouri?

You’ll need to collect sales tax in Missouri if you have nexus there. There are two ways that sellers can be tied to a state when it comes to nexus: physical or economic. Physical nexus means having enough tangible presence or activity in a state to merit paying sales tax in that state. Economic nexus means passing a states’ economic threshold for total revenue or the number of transactions in that state.


Do you have physical nexus in Missouri?

Missouri considers a seller to have physical nexus if you have any of the following in the state:

  • An office or place of business
  • An employee present in the state for more than 2 days per year
  • Goods in a warehouse
  • Ownership of real or personal property
  • Delivery of merchandise in Missouri in vehicles owned by the taxpayer
  • Independent contractors or other representatives in Missouri for more than 2 days per year

Do you have economic nexus in Missouri?

To date, Missouri has no economic nexus laws; but legislation is constantly evolving with new states being added frequently. Recently, Missouri introduced bill S.B. 97.

Missouri’s S.B. 97 would establish that marketplaces are required to collect on behalf of 3rd party sellers and that any remote business who grosses more than $100,000 in sales in the previous twelve months must begin collecting Missouri sales tax from buyers.

Interestingly, this law would also actually lower Missouri’s sales tax rate starting in 2023.

If it passes, the law will go into effect on January 1, 2022.

However, even though there are not economic nexus laws in place, physical nexus laws still apply so you may have a requirement for sales tax in Missouri if you meet the physical criteria.


Is what you’re selling taxable?

Services in Missouri are generally not taxable. However– if the service you provide includes selling, creating or manufacturing a product, you may have to deal with the sales tax on products.

Tangible products are taxable in Missouri, with a few exceptions. These exceptions include certain prescription medicine and medical devices, and machinery and chemicals used in agriculture and manufacturing, among other things.

Collecting Sales Tax

The sales tax rate you collect in Missouri depends on whether you are based in Missouri or out-of-state.

How to Collect Sales Tax in Missouri if You are Based in Missouri

Missouri is an origin-based sales tax state. So if you live in Missouri, collecting sales tax is fairly easy. Collect sales tax at the tax rate where your business is located.

You can look up your local sales tax rate with TaxJar’s Sales Tax Calculator.

If you have more than one location in Missouri, then you would base the sales tax rate you charge on the point of origin of your sale.

How to Collect Sales Tax in Missouri if you are Not Based in Missouri

This scenario is a bit more complicated. If you are not based in Missouri, but have sales tax nexus in Missouri you are considered a Missouri “remote seller.” This is where things get challenging, since remote sellers are required to collect “use tax,” which is similar to sales tax, but can vary slightly from Missouri sales tax rates. If you’re running into this problem as an online seller, no worries! The TaxJar API will make sure you collect the right rate every time.

When are Returns Due?

When you file and pay Missouri sales tax depends on two things: your assigned filing frequency and your state’s due dates.

How often will you file sales tax returns in Missouri?

States assign you a filing frequency when you register for your sales tax permit. In most states, how often you file sales tax is based on the amount of sales tax you collect from buyers in the state.

In Missouri, you will be required to file and remit sales tax either monthly, quarterly or annually.

Missouri sales tax returns are generally due the 20th or the final day of the month following the reporting period. If the Missouri filing due date falls on a weekend or holiday, sales tax is due the next business day.


Filing Sales Tax

When it comes time to file sales tax in Missouri you must do three things:

  1. Calculate how much sales tax you owe
