Missouri’s economic nexus threshold is $100,000 in gross sales into Missouri in the current or prior 12-month period. Once exceeded, registration and collection are required.

Missouri was one of the last states to enact economic nexus legislation, effective January 1, 2023. Marketplace-facilitated sales count toward the threshold. There is no transaction count alternative threshold.

Tax Rate — State and Local Complexity

Missouri’s state rate is 4.225% — an unusual figure reflecting the combination of a base 4% rate with specific municipal and state levies baked in at the state level.

Local rates add substantially on top:

• State: 4.225%
• County: typically 0.5%–2.0%
• City: typically 1%–3%
• Special districts: additional overlays
• Combined in Kansas City: approximately 8.6%–8.975%
• Combined in St. Louis City: approximately 9.679%

Missouri has over 2,000 local taxing jurisdictions — one of the highest counts in the US. This makes accurate destination-based rate calculation complex. Rate APIs (Avalara, TaxJar) are strongly recommended over static ZIP code tables.

Product Categories

Taxable: Tangible personal property, most retail goods, prepared food.

Exempt: Prescription drugs, most groceries (food for home consumption is exempt from state rate), qualifying agricultural inputs, manufacturing equipment and machinery.

Grocery exemption: Missouri exempts food and food ingredients for home consumption from the state rate. Local jurisdictions may still tax groceries at local rates.

Digital Goods and SaaS

Missouri does not tax SaaS or most digital goods. The Missouri DOR’s position is that software-as-a-service and other digital products lacking a tangible form are not subject to sales tax.

Missouri’s digital goods framework:

• SaaS — not taxable; Missouri has consistently held that remote access to software is not a taxable sale of tangible personal property
• Downloaded software — Missouri’s position on electronically delivered software has been less definitive; some downloads may be taxable if treated as the sale of a tangible product in electronic form. Current guidance leans toward non-taxable for most electronic delivery
• Digital content (streaming, ebooks) — generally not taxable
• Online subscriptions — generally not taxable

For SaaS and digital-only businesses, Missouri is generally a non-taxable state.

Compliance Notes

2,000+ local jurisdictions: Missouri’s local tax complexity is extreme. Use a real-time rate calculation API for accurate destination-based collection. Static rate tables by ZIP code are often inaccurate in Missouri.

Missouri enacted nexus late: Missouri’s economic nexus law took effect January 1, 2023 — later than most states. If you have sold into Missouri for years, your obligations began in 2023, not 2018 like most states. Review your back-period exposure from 2023 onward.

Not SST: Missouri is not an SST member. Multi-state SST registration does not cover Missouri.

SaaS sellers: Missouri’s non-taxable position for SaaS means digital-only sellers likely have no collection obligation. Monitor DOR guidance for changes.

Origin vs destination: Missouri uses destination-based sourcing for remote sellers (no physical Missouri presence). Missouri sellers with physical presence use origin-based sourcing for intrastate sales.
