To register select the Register Now button. Otherwise, enter your user ID and password. Kansas doesn’t require anything in writing for a transmitter to send an employer’s 1099 information to the department on their behalf. If you are a transmitter and you don’t want to access the employer’s accounts then the transmitter would be required to register on the Kansas Department of Revenue’s Webtax system for access into our system.
