Your property may be prorated over two parcels. This does not mean you are paying more in taxes; it simply means that your home straddles two parcels and a portion of the assessed value is spread over those two parcels. This results in two separate Property Index Numbers (PINs) but no added tax liability. You may find more information about consolidating your PINS here: https://www.cookcountyassessor.com/divisions.

Please Note: Filing a consolidation will not affect or reduce the amount of your overall assessment of your property, or your taxes due.

The Cook County Assessor’s Office will send applications directly to tens of thousands of new homeowners who purchased their property before January 1, 2021. If you are one of these new homeowners, and our Office has received data about your home purchase, your application should arrive in the mail in March 2022, or you can apply online.

Please Note: If you received the Homeowner Exemption on your second installment bill last year and your residency did not change, you do not have to reapply. You will continue to receive the benefits of the exemption each year.

Yes. Your first installment bill for tax year 2020 is not affected by an appeal of a 2020 assessment (or a 2021 assessment).

You may locate your property index number on the following:

• your tax bill,
• your property deed,
• your closing documents from the purchase of your home,
• your reassessment notice, and
• notices from the Assessor’s Office if the underlying parcel has been divided, (i.e. condominiums, new subdivisions)
