DuPage County and Cook County property taxes are among the highest in the country. Many are also wrong — assessments based on comparable properties that aren’t comparable, or outdated valuations that don’t reflect current condition. We file the appeal that lowers your bill.

We’ve handled this specific area of real estate law for DuPage County clients for over three decades. We integrate it with our broader real estate practice — closings, title, leases, litigation — so you get one team handling all aspects of your matter.

Property Tax Appeals FAQ

Common Questions

Often yes — particularly if your assessment is out of line with comparable properties, your property has condition issues affecting value, or your township reassessment overshoots actual market value. Roughly 30-40% of appeals result in reductions.

The Board of Review opens annually after the assessor’s office publishes assessments — typically late summer through fall. Each township has its own filing deadline. Miss the window and you wait until next year.

Depends on the over-assessment. Successful appeals of 10-30% reductions in assessed value are common. On a $400K home with a 20% reduction, savings are typically $1,500-3,000 per year — and reductions can carry forward for years.

Usually no — most board hearings are decided on the written submission. Some commercial cases or contested matters require appearance. We handle the entire process for you.

Most property tax appeal attorneys (including us) work on contingency for residential appeals — a percentage of the first year’s tax savings. No savings = no fee. Commercial appeals may be hourly or contingent depending on complexity.
