Direct answer
In the USA, registration depends on the business structure and location and often involves a state-level filing agency. The SBA advises choosing a business location and structure first, because they affect taxes, liability and filing obligations, then registering with the state filing agency, appointing a registered agent where required, obtaining federal and state tax IDs, and checking state and local licences.
Overview
The SBA explains that location and business structure affect registration, tax, licensing and permitting requirements, with state and local variation.
