Kentucky Law requires employers to withhold income tax for both residents and nonresidents employees (unless exempted by law). Employers must withhold the income tax of the employees receiving "wages" as defined in Section 3401(a) of the Internal Revenue Code.
Kentucky Withholding Tax Laws are located in Chapter 141 of the Kentucky Revised Statutes.
K-4E Special Withholding Exemption Certificate
Employers: The Kentucky Department of Revenue strongly encourages all employers to utilize Form K-4E, Special Withholding Exemption Certificate when applicable.
This certificate should be completed by employees that anticipate no Kentucky Income Tax liability. If the employee is eligible to claim this exemption, the employer will not withhold Kentucky income tax from wages. This certificate may be used instead of Form K-4 by those employees qualified to claim the exemption.

This method is offered at no cost to the employer.

Submission of Wage and Tax information must be filed on or before January 31.
Department of Revenue will assign a personal identification number (PIN) when the employer declares an intention to send annual wage and tax reports to Department of Revenue via the Web. To register, use the Authorization to Submit Employees Annual Wage Statements Via DOR Web Site - Form 42A808.
Filers who registered to use the FTP software from previous years are already registered to use the web site. The PIN doesn't change. If you have forgotten your PIN number, send an e-mail. The FTP software previously used will no longer work for any tax year.
If you have already registered and are ready to transfer your withholding information, go to E-file and Payment Options in the top right hand corner of most of the pages within the DOR webpage.
