Missouri use tax applies at the same rate as sales tax when you purchase taxable goods from out-of-state vendors who do not collect Missouri sales tax. Businesses must report and pay use tax on their regular sales tax return. Common triggers include online purchases, out-of-state equipment, and supplies from non-collecting vendors.

Does Missouri have marketplace facilitator rules?

Missouri requires marketplace facilitators meeting the economic nexus threshold to collect and remit sales tax on behalf of third-party sellers. Major platforms including Amazon, eBay, Etsy, and Walmart Marketplace collect Missouri sales tax on marketplace transactions. Sellers using these platforms are not required to collect on marketplace sales but remain responsible for direct sales.

What are the penalties for sales tax non-compliance in Missouri?

Missouri imposes penalties for late filing and late payment, typically 5-10% of the tax due per month (capped at 25-50%). Interest accrues on unpaid balances at a rate set annually. Failure to file returns can result in the state estimating your liability and potentially revoking your sales tax permit. Fraud or willful evasion can result in criminal penalties including fines and imprisonment.
