EIN vs Missouri tax registration

The EIN is federal. Missouri DOR registration is state-level. Missouri DOR’s online business registration covers tax types such as sales tax, vendor’s use tax, consumer’s use tax, withholding tax, unemployment tax, tire and lead acid battery fee, and corporate income tax.

DOR also says a business must obtain a sales tax license by registering if it makes sales of tangible personal property or taxable services, and should register if it has employees and must remit withholding tax.
