Close or update a business license

Find instructions for closing a license or reporting ownership, address or business changes.

Before you start

  • Start with where your business is located and where it will operate. A county license may apply only to unincorporated areas or specific activities; cities can have their own requirements.
  • Some county offices provide guidance or referrals and do not issue a general business license. Read the entry before choosing an application.
  • A business license or tax certificate, an FBN/DBA filing, business entity registration and a professional license serve different purposes. Zoning, health and other activity permits may also apply. Business stormwater registration is a separate local programme where required.
  • Check the license period, renewal date and rules for changes in ownership or location. A renewal may not cover a move or a new owner. Fees and application steps depend on the license category.
