Who needs a business registration: sales tax permit, employer withholding in Oklahoma?

Issued by Oklahoma Tax Commission (OkTAP), at step 2 of 6 in the opening sequence: register for tax.

Every kind of business in Oklahoma

The Oklahoma table lists this for every kind of business.

Register on OkTAP before the first sale; the permit must be posted at each location. The same registration opens the withholding account once you have employees. Cities and counties add their own sales tax on top of the 4.5% state rate, all collected on the one return.
