Kentucky Department of Revenue Gateway

The Kentucky Department of Revenue (KDOR) has developed a Gateway to provide electronic filing of Kentucky tax forms.  Data is transmitted in an xml format based on schemas. 

The KDOR Gateway is used for the bulk filing of the Kentucky Employer's Return of Income Tax Withheld: 

  • Form K-1
  • Form K-3
  • Form K-1 and K-3 Amendments

Note:  The  KDOR Gateway is not available for individual business taxpayers.  Please visit the Kentucky One Stop Business Portal (https://onestop.ky.gov) for individual business electronic filing options. 

Withholding Tax - Bulk Filing through the KDOR Gateway

Bulk filing enables companies to submit large numbers of filings in a single file.   Bulk filing is used primarily by payroll companies to submit employer withholding taxes to the Kentucky Department of Revenue.  

Getting Started

For details regarding how to become a Bulk Filer please refer to the KYDOR Gateway Registration Overview for a step-by-step guide on how to become a Bulk Filer.  Bulk Filers are invited to complete the Letter of Intent/Nondisclosure Agreement and e-mail it to KDOR's bulk filing coordinator to get registration started. 

Schemas

The schemas are based on FSET schemas and modified for Kentucky use.   The schemas will be included with the onboarding documents provided after the Letter of Intent/Nondisclosure Agreement is received.

Testing

A series of tests will need to be submitted to verify the functionality and compatibility of your software with the KDOR Gateway. Provided that the tests are completed and the correct results received, the applicant will be notified that they have been certified for Bulk Filing.   Once we process your registration, we will work with you to test your ability to transmit test filings and provide you with testing information.
