State Tax Registration Requirements

​​​​​For many businesses in Kentucky, the state tax process begins by completing a Kentucky Tax Registration Application. This document, allows a business owner to register for the most common tax types for Kentucky businesses. The Kentucky Business One Stop allows you to file the form online in a fast, free and convenient way. Most businesses should have completed a Kentucky Department of Revenue Tax Registration Application in Step 2 of the Start page on Kentucky Business One Stop.

By completing the One Stop registration with the Department of Revenue, your business will automatically enroll for the most common business taxes including:

  • Employer’s Withholding Tax
  • Sales and Use Tax (for businesses operating as wholesalers, retailers or sellers in Kentucky)
  • Transient Room Tax
  • Motor Vehicle Tire Tax
  • Consumer’s Use Tax
  • Corporation Income Tax
  • Limited Liability Entity Tax
  • Coal Severance/Processing Tax
  • Coal Seller/Purchaser Certificate ID Number
  • Telecommunications Tax
  • Utility Gross Receipts License Tax

Some sole proprietorships that don't have any employees and that are involved in certain service type businesses (where sales and use taxes or other special taxes don't apply) are still subject to business income taxes, but may not be required to complete a Kentucky Tax Registration Application. Contact the Kentucky Department of Revenue for additional information on state tax obligations and registration requirements.

Special Tax Registration Requirements

Depending on the product or service your business provides, there may be other state taxes that apply to your business. Most of these require that you file a special application/registration with the Department of Revenue.
