Register ​Online

Kentucky Business One Stop (One Stop), a simple online registration system, is the quickest and easiest way to register your business with the Kentucky Department of Revenue (DOR) and Kentucky Secretary of State. You can register your business in about 30 minutes and you receive your tax account numbers almost instantly. You will be notified by email that your application has been received and is being processed. Once your business is registered with One Stop, you will have online access to manage and update your business information anytime you want, including the ability to e-file certain tax returns, print permits, and apply for other tax accounts, as needed. Additionally, all correspondence from DOR will be available electronically through the One Stop Message Center for businesses that are registered in the online system.

Paper Registration   If you do not have access to Kentucky Business One Stop, you can still apply for registration on a paper form: Form 10A100, Kentucky Tax Registration Application.  If you file a paper application it will take longer for DOR to process your application (approximately 5-10 business days).  You also will need to complete a second application if you wish to register for online filing of returns.

  • Once you have completed sections A, B, C & E you will find DOR contact information on page 9.
  • Applications with extensive amounts of missing information will be returned by mail for further completion.
