Registering your business as a foreign entity (out-of-state seller) in new states

Before a company can register for sales tax in most states -- or before Zamp can register on their behalf -- it must first register as a business. Many states have different registration processes for in-state versus out-of-state businesses. This resource is for companies registering as out-of-state sellers, where you don't have physical locations, employees, or (in some cases) inventory stored in the state.

If you have not already registered your business in a state, your sales tax registration application will be rejected, because the state will not have a record your EIN being registered for general business purposes.

The links below can be used to register your business as a foreign entity in new states.
