Was Norwood Park Township reassessed in 2026?
No. Norwood Park is in the north suburbs, which the Assessor is not reassessing in 2026. Here a property is reassessed only if there is a change due to division work, permit applications or other special circumstances; then the owner gets a Reassessment Notice.
You can still appeal in 2026. The Assessor's calendar lists Norwood Park with its own appeal window for this year.

How to file in Norwood Park 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 Norwood Park, 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 Norwood Park Township appeal deadline in 2026?
The Assessor's last file date for Norwood Park Township is May 26, 2026. The Board of Review window is August 3, 2026 to September 1, 2026.
I missed the Assessor deadline. What now?
Both 2026 windows have closed. You can still look at a Property Tax Appeal Board appeal after a Board of Review decision, claim missed exemptions for past years, and appeal next year.
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 Norwood Park Township reassessed in 2026?
No. The north suburbs and the City of Chicago are not reassessed in 2026, except properties with division work, permits or other special circumstances. You can still appeal.
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.
