Online Appeal Filing

Starting in 2019, all property assessment appeals must be done electronically. Property owners can appeal their assessment on their own through the Lake County Board of Review. No attorney is required for a residential appeal. To appeal a property assessment, use the SmartFile E-Filing Portal

Prior to filing a formal appeal to the Board of Review, property owners should contact their local township assessors office to discuss their concerns. There is a 30-day deadline from the date of publication to file an assessment appeal. The filing deadline for each property is listed on the assessment notice
