Origin vs destination sourcing in MO

Missouri is split: in-state sellers use origin-based sourcing (charge buyer the rate at the seller's location). Out-of-state sellers and marketplace facilitators use destination-based sourcing (charge buyer the rate at the delivery address). This makes MO uniquely complex for multi-channel sellers.

The economic nexus law (SB 153, effective 2023)

Missouri was the last state to adopt economic nexus after Wayfair. Out-of-state sellers must register and collect once they exceed $100,000 in MO gross receipts in the prior 12 months. Marketplace facilitators (Amazon, Walmart, Etsy) collect MO tax on third-party sales since January 2023.

Reduced grocery rate (not exempt)

Missouri taxes grocery food at 1.225% state (vs 4.225% general), but local taxes typically still apply at the full local rate. So a grocery purchase in St. Louis is 1.225% + 5.45% ≈ 6.7%, not zero. Several 2024 ballot measures to fully exempt groceries failed.
