City and county taxing offices
Information on: If your city or county has business taxes and you are located within the city limits, you will need to register with the city taxing authority, such as the city auditor. Businesses located outside city limits should register with the county taxing authority, such as the county clerk’s office. Also, remember to contact your county assessor as soon as your business opens. Businesses are required to report personal property – assets used in the operation of a business – to the assessor. Personal property includes furniture, office equipment, machines, and supplies used in the course of doing business.
