Was Rich Township reassessed in 2026?

Yes. Rich is in the south and west suburbs, which the Assessor reassesses in 2026. Cook County reassesses each area once every three years, so every owner here gets a Reassessment Notice with the property's characteristics and an updated estimated market value.

The Assessor publishes residential valuation reports for each township it reassesses: valuation reports. A higher value does not mean the bill goes up by the same amount: your bill depends on your share of the total value, exemptions and local levies.

How to file in Rich Township

Confirm your PIN and township. Use the Assessor's address search or our free check below.
Check the notice. The Assessor's rule of thumb: if the characteristics on your notice are correct and the estimated market value is within 10% of what you think your home is worth, an appeal is unlikely to change much. Wrong square footage, rooms or other characteristics are a reason to appeal.
File online with the Assessor. On the county's online appeal site choose the residential appeal (or "Residential with Comparable Grid" if you argue lack of uniformity). The Assessor says filing is free and can take as little as 20 minutes, and that you don't need to hire anyone.
Comparables are optional. Assessor analysts review similar homes themselves. You may attach up to 6 comparable PINs from your neighborhood that resemble your home in size and style.
Board of Review is a second chance. When the Board opens Rich, you can file there too (online, free). Individual owners may represent themselves; the Board's decision sets the final county value for the year.

Questions

What is the Rich Township appeal deadline in 2026?

The Assessor has not published Rich Township's 2026 dates yet. They appear on the Assessor's calendar when notices are mailed.

I missed the Assessor deadline. What now?

You can still appeal to the Board of Review when it opens your township, even if you did not appeal to the Assessor.

Should I appeal to the Assessor or the Board of Review?

You can do both. The Assessor's window comes first; the Board of Review is a separate agency and its decision sets the final county value for the year.

Was Rich Township reassessed in 2026?

Yes. The south and west suburbs, including Rich, are reassessed in 2026, so owners get a Reassessment Notice with an updated estimated market value.

Can appealing raise my assessment?

Under Illinois law (35 ILCS 200/16-95) the Board of Review may not increase an assessment unless the owner is first notified in writing and given a chance to be heard.

I think I missed an exemption. Can I get it back?

Missed homeowner and other exemptions for past years can be requested from the Assessor through a Certificate of Error. The Assessor's page currently lists tax years 2021 to 2025 for the homeowner exemption.
