Starting a service business in Missouri comes down to four things: picking a structure, registering with the state, getting licensed for your trade, and setting up a way to bill customers. Filing an LLC in MO costs $50, ongoing reporting is $0 (no annual report), sales tax is 4.225% + local, and personal income tax runs 0%–4.8%. Below is the full sequence, the fees you should budget for, the licenses most trades need, and the deadlines that catch new Missouri owners off guard.
Most new registrations come out of Kansas City, St. Louis, Springfield and the rest of Missouri — local business licenses are issued at the city or county level, so check yours after the state filing clears.
| Item | MO cost |
|---|---|
| LLC / entity filing (one-time) | $50 |
| Annual / periodic report | $0 (no annual report) |
| Federal EIN (IRS) | Free |
| Sales tax registration | Typically free |
| Trade / professional license | Varies by trade |
| Local business license | Set by city / county |

Online LLC filings with the MO Secretary of State are typically processed in a few business days, and an EIN from the IRS is issued immediately online. Trade licensing and local permits usually take longest — plan on two to six weeks before you're fully cleared to work, depending on your trade.
No — you can operate as a sole proprietor in Missouri and still invoice customers legally. An LLC ($50 to file, $0 (no annual report)) separates your personal assets from business liability, which matters most once you're on customer property, hiring help, or signing contracts.
Missouri sales tax is 4.225% + local. Materials and goods are commonly taxable, while labor treatment depends on the type of work, so bill parts and labor as separate lines and register with the Missouri Department of Revenue before you start collecting.
