Streamlined sellers who have Iowa retail locations need to register those locations at the online Iowa Business Tax Registration site, if they are not already registered. Registered retail locations in Iowa will receive a separate Iowa sales tax permit. The Iowa sales tax permit number will be used as the Location ID when filing the semi-annual information report.
Registering for other Iowa permits, including hotel/motel, auto rental, and household hazardous material, can also be done at that site.
