Who issues a Sales Tax Registration in Missouri

In Missouri, a sales tax registration is issued by the office below. That is the office to confirm every figure with.

Missouri — the state revenue or taxation department (handles state tax registration and permits)

Starting point for anything else in Missouri: the state business portal, https://bsd.sos.mo.gov. It is a starting point, not the issuer of this permit.

The general US process

This sequence is the shape the process takes across the US. It is not a list of Missouri requirements, and no step here should be read as one — the issuing office named above sets the actual requirements.

Step 1: Work out whether you have nexus in the state — physical presence, staff, inventory, or sales above the threshold the state sets for remote sellers.
Step 2: Register with the state revenue department. Registration is free in most states.
Step 3: Collect the permit number the state issues, and keep it — the reseller permit is built on it.
Step 4: Note the filing frequency the state assigns you. It is based on expected volume, not on your preference.
Step 5: Charge the rate the state's sourcing rules point at. Many states tax at the buyer's address rather than the seller's.
Step 6: File on schedule even in periods with no sales where the state requires a zero return.

What varies: whether the state has a sales tax at all (five do not), the economic nexus threshold, the sourcing rule, and the filing calendar.

Documents usually asked for

A typical list, not a Missouri checklist.

EIN
Business address
NAICS code
Expected monthly taxable sales estimate

Heads up: The government fee is the floor. Filing services will quote you several times that to handle it. For a simple setup the official route is usually straightforward; for a complicated one — multiple states, unusual ownership — paying someone can be the cheaper mistake to avoid.
