What is my Taxpayer ID for E-filing purposes?
This is your current KIT, KYU or IFTA number. Your Taxpayer ID for IFTA for E-Filing purposes is the same number that you used when filing your paper Reports in the past, but without the “KY-” prefix. For example, if you filed your paper Reports using Taxpayer ID KY-123456789, you will enter 123456789 for E-Filing purposes.
