A payer of nonpayroll payments that withheld federal income tax or backup withholding must file only one Form 945 per year.Complete a new Form W-4, Employee's Withholding Allowance Certificate, and submit it to your employer. DOR has created a withholding tax calculator to assist employers in computing the correct amount of Kentucky withholding tax for employees. Individual Tax Number (ITN) applications should be submitted separately from your disposition request to avoid delays. Have back rent and need assistance? REET also applies when there's a transfer of controlling interest in entities that own real property in the state. Submit the completed form to our office.
