Lake County Property Tax Assessments

The Lake County Chief County Assessment Officer sets values on all property in the county. The office is at 18 N County Street, 7th Floor, Waukegan. Call (847) 377-2050 or email assessor@lakecountyil.gov for help. Under 35 ILCS 200, property in Lake County gets assessed at 33.33% of fair market value. The assessor looks at recent sales, property features, and market conditions to arrive at a value.

If you think your assessment is wrong, you can file a complaint with the Lake County Board of Review. The Board checks your evidence and can adjust the value. After that step, you can appeal to the Illinois Property Tax Appeal Board. These appeal records become part of your Lake County property tax records and stay in the assessor's system going forward. The assessment office also handles changes like new construction, demolitions, and property splits that affect how a parcel is valued.

The Lake County exemptions page explains each type and how to apply for property tax reductions.
