Missouri Sales Tax Nexus: Economic Nexus Threshold (2026)
Missouri's economic nexus threshold for remote sellers is $100,000 in sales, measured over the preceding 12-month period, tested at the end of each calendar quarter. Marketplace sales count toward Missouri's threshold. Only taxable sales count. Inventory or another physical presence in Missouri generally creates nexus regardless of sales. The state rate is 4.225%, plus local taxes.

What to do after crossing the Missouri threshold
When it starts:
- Timing: at the end of each calendar quarter, check the preceding 12 months; if over $100,000, collect vendor's use tax no later than three months after the close of that quarter.
- Confirm the numbers. Check your Missouri sales against the measure and period in the key facts above (taxable sales only).
- Register before you collect. Use Missouri's official registration page. Collecting a state's tax without a registration is generally not allowed.
- Collect and file. Charge Missouri sales tax (plus any local taxes that apply at the delivery address) on taxable sales from the start date, and file returns on the schedule the state assigns. Marketplaces generally collect on the sales they facilitate, so you usually collect on your direct sales.
- Look back. If you crossed the threshold in an earlier period and did not register, get advice on those periods. Many states have voluntary disclosure programs that may limit penalties.
Physical presence and inventory in Missouri
Inventory or other property in the state (including Amazon FBA or 3PL warehouse inventory), employees, or an office generally creates physical-presence nexus regardless of the economic threshold.
Marketplace sellers in Missouri
Do marketplace sales count toward your own threshold? Yes, counted.
Missouri DOR FAQ: a seller that also makes independent sales must register if its total gross receipts, including those made through the marketplace facilitator, exceed $100,000; it then remits only on its direct sales. Sellers using only a marketplace facilitator need not register.
