Missouri Local Tips: Before You Use the Wrong Office
Missouri DOR touches taxes, driver licenses and motor vehicles, but several tasks still involve other agencies or local offices. Use these practical Missouri tips before you waste time on the wrong page.
Secretary of State is not DOR
If you need to form an LLC, search a corporation, file an annual registration or manage business entity records, start with the Missouri Secretary of State. If you need sales tax, withholding, corporate income tax or MyTax registration, use Missouri DOR.
County collector vs DOR
Personal property tax, real estate tax bills and many local property payment questions usually start with the county collector or assessor, not a normal DOR individual income tax account.
St. Louis and Kansas City local taxes
Large metro areas may have local rules, city earnings taxes, license requirements or local sales tax layers. Confirm city/county obligations separately from state DOR obligations.
Call-before-visiting strategy
License offices and DOR office functions vary by service. Call or use the license office locator before visiting, especially for title problems, REAL ID documents, reinstatement, testing questions or business tax account issues.

Missouri Business Owner Workflow: Secretary of State ā IRS ā Missouri DOR ā Local License

| Step | Where to go | Why it matters | Common mistake |
|---|---|---|---|
| 1. Business entity | Missouri Secretary of State | Forms or searches LLCs, corporations and entity records. | Thinking DOR forms the LLC. |
| 2. Federal EIN | IRS | Needed for payroll, banking and many tax accounts. | Paying unnecessary third-party EIN fees. |
| 3. State tax account | Missouri DOR / MyTax | Registers sales tax, use tax, withholding and other Missouri tax accounts when required. | Selling taxable items before registering. |
| 4. Local license | City or county office | Many local governments require business licenses or occupational rules. | Assuming state tax registration replaces local rules. |
| 5. Industry license | Specific state/local board | Alcohol, tobacco, contractors, professional services and regulated businesses may need extra approvals. | Only registering with DOR and ignoring industry licensing. |
Missouri Sales and Use Tax: State Rate, Local Rates, MyTax Filing and Exemptions

Missouri Employer Withholding Tax: MO W-4, Zero Returns and 2026 Tables
