The 2017 Instructional Information for Township Assessors is now available to the general public.

The Winnebago County Supervisor of Assessments is required to assemble all Township Assessors annually and instruct them in uniformity of their functions.  The meeting for 2016 assessments was held on December 18, 2015.  The information presented at the meeting also needs to be made available to the general public.  We are making it available by posting it on our website.  This information should serve to keep the taxpaying public better informed and demonstrate our commitment to openness and transparency.

Select "Homestead Exemption Information" on the right and select the "2017 Rental/Owner Occupancy Exemption Application" form from the drop-down.  Print the form for completion.  The application and a copy of the lease verifying occupancy on January 1, 2017 by the tenant listed on the application are required to qualify for the exemption.  The application and lease are due before April 1, 2017.
