Assessment Notices
Lake County property owners will receive their property assessment notices in the mail during mid to late summer. It’s important for taxpayers to read, understand and check this notice for accuracy as it contains important information about their property. Taxpayers are encouraged to contact their local township assessor’s office if they have questions regarding the valuation of their property.
After assessments are published for each township, a property owner has 30 days to appeal their assessment if they so desire. Scroll down to view a schedule of publication dates and appeal deadline dates by township.
Understand Your Property Assessment
Staff members from the Chief County Assessment Office are available during regular business hours to assist Lake County property owners who need help understanding or appealing their assessments, or who want to learn about homestead exemption, which can potentially provide tax relief. Due to the COVID-19 Pandemic, please call with your questions or concerns prior to visiting our office.

Appeals Must Be Filed Electronically
Property owners can appeal their assessment through the Lake County Board of Review on their own. No attorney is required for a residential appeal. The deadline date for each property is listed on the assessment notice.
Prior to filing a formal appeal to the Board of Review, property owners are encouraged to contact their local township assessor’s office to discuss their concerns.
To file an appeal, all property owners need to begin the process using the Chief County Assessment Office’s SmartFile E-Filing Portal. For property owners in all but five of Lake County’s townships, the entire appeal process can be conducted through this portal.
