The launch sequence
Federal first, then Missouri. The federal side is identical in every state and is covered in depth by how to get your own authority; the state facts below come from our sourced Missouri data.
- Get a USDOT Number. Register with FMCSA first; Missouri references it on the state side and most credentials require it.
- Apply for PSC intrastate authority. For-hire carriers file with the Missouri Public Service Commission and have insurance filed by their insurer.
- License for IFTA and IRP if you run interstate. Through the Missouri Department of Revenue, one quarterly fuel return and one apportioned plate set covers multi-state running.
The order that works in Missouri
Federal first. Get the USDOT Number, and if you will haul for hire across state lines, the federal operating authority and insurance filings that go with it. Then the state layer: apply for PSC intrastate operating authority as a for-hire carrier, with your insurer filing proof of coverage. If you cross state lines, register for apportioned plates (IRP) and license for IFTA with the Department of Revenue so one quarterly return covers your fuel tax everywhere you run.
Permits come last, and only if your loads need them. Oversize or overweight work means an MISS permit account, and route-level rules like escorts attach to each move.
Where Missouri differs from other states
Missouri consolidates fuel tax and apportioned registration under the Department of Revenue rather than a standalone motor carrier division, while the PSC owns intrastate operating authority. The state does not levy a weight-distance tax, so interstate carriers in Missouri file IFTA but not a separate mileage tax.
The Missouri facts you will need
The complete tables live on the dedicated pages: intrastate authority, IRP registration, IFTA, and trucking permits.
Budget the launch before you file
The trucking startup cost calculator builds a line-item estimate from the sourced fee data, and the cost pillar explains every line. Neither replaces a quote for your truck and insurance, which are the two biggest variables.
Common mistakes when launching in Missouri
Skipping the USDOT Number
Missouri references the USDOT Number on the state side; filing state credentials without it stalls the application.
Assuming federal insurance settles the state minimum
Missouri sets its own liability minimums by operation type; confirm the state floor before you bind coverage.
Running interstate without IFTA or IRP
Without apportioned plates and an IFTA license you need temporary trip and fuel permits for every out-of-state move.
