Wholesale & Distribution Bookkeeping in Missouri

A wholesale sale in Missouri is exempt because you hold a valid resale certificate for that buyer, not because the buyer said they were a reseller. The Missouri Department of Revenue looks at the certificate file, and a sale with no certificate behind it is treated as a taxable retail sale with the tax coming out of your margin rather than the customer's pocket. Local rates vary widely and are sourced by jurisdiction, so effective rates swing several points across the state. Certificates expire, businesses change entities, and a file that was complete three years ago is not complete now — which makes reviewing it a scheduled task rather than something done when a letter arrives.

Drop shipping puts three parties in three possible states on a single transaction, and Missouri has to decide whether the supplier shipping into it owes tax, whether your resale certificate from another state is acceptable here, and whether you have an obligation of your own. Missouri sets economic nexus at $100,000 in sales, which is the threshold that decides whether the last question is even live. The books make this answerable by recording where goods actually shipped rather than only who was billed — a distinction most order systems capture and most bookkeeping ignores.

Economic nexus in Missouri is $100,000 in sales. For wholesale and distribution, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the Missouri Department of Revenue and begin collecting. We track your Missouri sales against it and tell you before you cross, not after.

Missouri assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because Missouri includes an annual bracket, a low-volume seller here can go a full year between filings, which is exactly when a liability account drifts unnoticed. We reconcile it monthly regardless of when the return is due.
