Property Tax Exemptions


The General Homestead Exemption Application reduces the equalized assessed value, up to $6,000. It is available for all owner-occupied residences. No age requirement. Click HERE for the General Homestead Exemption Application form. This exemption is the only exemption handled by the Grafton Township Assessor.

The Homestead Improvement Exemption reduces the EAV of an owner-occupied property, up to $25,000 assessed ($75,000 market value) based on the value of a qualifying new improvement added to the existing assessment. This exemption lasts for 4 years after the new improvement is complete. You need not file an application. The Assessor will apply this exemption and verify the amount to the County Assessment Office.

The Grafton Township Assessor's Office will assist homeowners in completing various Homestead Exemption forms, but these applications are processed and granted or denied by the McHenry County Assessment Office. For information on available exemptions and corresponding forms, click HERE to be directed to the McHenry County Assessment Office.
