Assessment Notices

Lake County property owners will soon be receiving their property assessment notice in the mail. It's important for taxpayers to read, understand and check this notice for accuracy as it contains important information about their property. 

Assessment notices are sent to property owners at different times, depending on which township they live in. After assessments are published for a township, a property owner has 30 days to decide if they would like to appeal their assessment. Taxpayers are encouraged to contact their local township assessor's office if they have questions regarding the valuation of their property.

Understand Your Property AssessmentHelp Center

To help taxpayers evaluate their property assessment notice, the Chief County Assessment Office is hosting tax assessment help center sessions. At the sessions, property owners can talk one-on-one with taxpayer advocates to understand the information on their assessment, see how to use the County's new web applications and learn about homestead exemptions, which can potentially provide tax relief.

In Illinois, exemptions are available for general homestead, seniors, disabled persons, disabled veterans, returning veterans (within the last two years) and home improvements. Learn about the homestead exemptions available.

Property information can be searched free of charge at tax.lakecountyil.gov. Enter an address or property PIN number to view tax summaries, property history, exemptions, permits, sketches, sales history and a host of other property characteristics.

Seek help if you need assistance understanding your assessment, appealing online, or applying for homestead exemptions. Remember, an attorney is not needed for a residential appeal.
