The following goods and services are taxable in Missouri:

• Most Physical Goods: This includes items like clothing, electronics, and furniture.

Sales tax exemptions in Missouri apply to several categories, including:

• Groceries: Food purchased for home consumption is generally exempt from sales tax.
• Prescription Drugs: Medications prescribed by a licensed practitioner are exempt.
• Medical Devices: Certain medical equipment is exempt.
• Farm Equipment: Equipment used directly in agricultural production may qualify for an exemption.

For a complete list of tax-exempt items and specific conditions, refer to the Missouri Department of Revenue’s sales and use tax guidelines.

When Do Businesses Need to Collect Sales Tax in Missouri?

Businesses must collect Missouri sales tax when establishing a nexus in the state. Sales tax nexus refers to a connection or presence that requires a company to collect and remit sales tax to the Missouri Department of Revenue (DOR). Missouri recognizes two primary types of nexus: physical nexus and economic nexus.

1. Missouri Physical Nexus

A business has a physical nexus in Missouri if it meets any of the following criteria:

• Operates a brick-and-mortar store, office, or warehouse in Missouri.
• Has employees, agents, or independent contractors working in Missouri.
• Stores inventory within Missouri, including through third-party fulfillment centers.
• Participates in trade shows or sales events in Missouri.
• Provides delivery services using company-owned vehicles to transport goods to Missouri customers.

2. Missouri Economic Nexus

Even if a business does not have a physical presence in Missouri, it is still required to collect sales tax if it meets the state’s economic nexus threshold:

• Gross revenue exceeding $100,000 from sales into Missouri during the previous or current calendar year or
• 200 or more separate transactions involving taxable sales into Missouri.

Failure to comply with Missouri’s sales tax laws can result in penalties and interest charges. Commenda suggests referring to the Missouri Department of Revenue (DOR) guidelines to ensure compliance and avoid potential issues. Keeping up to date with their regulations will help you stay on top of your tax obligations.

Failure to Collect Iowa Sales Tax

Failing to collect and remit Missouri sales tax can have substantial financial and legal consequences for businesses. The Missouri Department of Revenue (DOR) enforces strict penalties and interest charges for non-compliance.

1. Penalties for Late Filing and Payment

If sales tax is not filed or paid on time, businesses can incur the following penalties:

Failure to File:

• 5% of the tax liability if not filed by the due date.
• Increases to 10% if unpaid after 30 days.
• An additional 15% penalty is charged if unpaid for 60 days.

Failure to Pay:

• 5% penalty if not paid by the due date.
• Increases to 10% if the payment is made 30 days after the due date.
• The penalty may rise to 15% if the payment is not made within 60 days.

Minimum Penalty:

• The minimum penalty is $5, even if the owed tax is negligible.

2. Interest Charges

Besides penalties, interest accrues on unpaid taxes from the due date. The interest rate is calculated as the federal short-term rate plus 3%.

3. Electronic Payment Penalty

If your business must pay electronically and fails to do so, you will incur an additional 10% penalty on the amount due.

To avoid these penalties, it is critical to file and pay on time and ensure accurate tax collection and remittance. Commenda suggests referring to the Missouri DOR guidelines to stay updated on their rules and regulations.

Missouri Sales Tax for Out-of-State and Amazon FBA Program Sellers

Out-of-state businesses selling to Missouri residents must comply with Missouri’s economic nexus rules. Remote sellers, including those using the Fulfillment by Amazon (FBA) program, must be aware of where their inventory is located and how it triggers sales tax obligations in the state.

For FBA sellers, keeping track of your inventory locations is essential. You can use the Inventory Event Detail Report from Amazon Seller Central to check if your inventory is stored in Missouri. If your products are located in Missouri, you are likely subject to Missouri’s economic nexus laws, meaning you must collect sales tax on sales made to Missouri customers.

Missouri’s Economic Nexus Rule requires remote sellers to collect sales tax once their gross sales exceed $100,000 or 200 separate transactions involving taxable sales into Missouri during the current or previous calendar year.

If you’re uncertain whether your sales trigger nexus in Missouri, it’s a good idea to consult a tax professional to ensure compliance with Missouri’s tax regulations.
