Missouri's Online New Business Registration, run jointly by the Department of Revenue and the Division of Employment Security, registers sales tax, vendor's and consumer's use tax, withholding tax, unemployment tax, the tire and lead acid battery fee and corporate income tax in one application. A business that already has a Department of Revenue account adds unemployment tax through DES's UInteract instead.
Businesses in the City of St. Louis must open an earnings tax account with the Collector of Revenue's Earnings Tax Department, using Form E-9, before they begin operating in the city. The city uses the business's FEIN or SSN as its earnings tax account number.
Kansas City, Missouri runs its own business registration. Form RD-100, the city's Registration Application, is required of all new businesses with activities within the city limits and can be filed online through the city's Quick Tax system.
Also on the Missouri list

What is different about Missouri
- Missouri does not require LLCs to file an annual report with the Secretary of State, although Missouri corporations file an annual or biennial registration report. Once the articles of organization are filed, a Missouri LLC has no scheduled report with its formation office, which is unusual among states.
- Missouri ties local business licenses to state tax compliance. A business that sells goods at retail must show a statement of no tax due from the Department of Revenue, covering sales and withholding tax, before a city or county will issue or renew its occupation license, and the statement has to be recent when it is submitted.
- The Department of Revenue keys the Missouri Tax ID number to the business's federal and state identity. If the IRS issues the business a new FEIN, or the Secretary of State issues a new charter number, the department says a new Missouri Tax ID number is likely; an old number can be reopened only if the business structure has not changed.
Before you apply
The SS-4 must match the Missouri Secretary of State filing; its charter number is a state index, not a tax ID.
Missouri EIN questions
How do I get an EIN number in Missouri?
File IRS Form SS-4 after the Missouri Secretary of State approves any formation filing; there is no Missouri EIN application. Missouri's Online New Business Registration, run jointly by the Department of Revenue and the Division of Employment Security, registers sales tax, vendor's and consumer's use tax, withholding tax, unemployment tax, the tire and lead acid battery fee and corporate income tax in one application. A business that already has a Department of Revenue account adds unemployment tax through DES's UInteract instead.
Is there a Missouri EIN or state tax ID number?
No; only the IRS issues EINs (also called the FEIN or federal tax ID). Missouri's own numbers are the charter number from the Missouri Secretary of State, the Missouri Tax Identification Number (MOID) from the Missouri Department of Revenue, the Employment Security account number from the Missouri Division of Employment Security, and the retail sales tax license from the Missouri Department of Revenue.
Is the Missouri Tax Identification Number (MOID) the same as my EIN?
No. The Missouri Department of Revenue assigns it when you register as an employer in MyTax Missouri. It goes in W-2 box 15; the EIN goes in box b.
Where do I register for Missouri unemployment insurance?
With the Missouri Division of Employment Security, online through UInteract. It assigns an Employment Security account number, a separate number from the EIN.
Do I need a Missouri retail sales tax license?
Only if you sell what Missouri taxes. The Missouri Department of Revenue issues it through MyTax Missouri, and your returns are filed under its number, not the EIN.
