Coming Soon! Cook County Board of Review Appeal Window

1024 683 Gayle Curcio

2022 was a property reassessment year for Northfield Township. Cook County follows a triennial reassessment cycle, meaning that a determination of each property’s fair market value and corresponding assessed value occurs once every three year for taxation purposes. This assessed value and exemptions help determine your share of property taxes owed.

The Cook County Assessor mailed the results of the 2022 appeals made to his office by Northfield Township property owners. You can also view your results online at

If you missed your chance to appeal with the Cook County Assessor last fall or you did appeal and believe your assessed value is still not equitable, there will be another opportunity (30-day window) beginning sometime in March 2023 to review your 2022 property assessed value and then file an appeal with the Cook County Board of Review (BOR) if helpful.

The Board of Review is a separate, quasi-judicial agency independent of the Assessor.  The Cook County Assessor sets the taxable value on all of the more than 1.8 million parcels of real estate located in Cook County. When each township reassessment is completed by the Assessor, property owners may appeal the assessment set by the Assessor at the Board.   The Board decision sets the final county valuation on the property for that tax year.

Once the Board of Review appeal window is open, we here at Northfield Township can review your assessment to be sure it is equitable and assist you to file an appeal if helpful.

Watch for BOR appeal window to open during March 2023

Senior Citizen Real Estate Tax Deferral Program Available Through Cook County Treasurer’s Office

1024 701 Gayle Curcio

Northfield Township Assessor Alida E. Nally, CIAO, wants to make residents aware that the Cook County Treasurer’s Office administers a program called Senior Citizen Real Estate Tax Deferral Program that aims to help keep senior residents in their homes.

The deadline to apply is March 1, 2023.

The Senior Citizen Real Estate Tax Deferral program is a tax-relief program that works like a loan. It allows qualified seniors to defer a maximum of $7,500 per tax year (this includes 1st and 2nd installments) on their primary home. The loan from the State of Illinois is paid when the property is sold, or upon the death of the participant.

Qualifications include:

  • Homeowners who are at least 65 years of age by June 1 of the year in which the applications are made.
  • Those whose household income is $65,000 or less.
  • Surviving spouses of previously approved applicants who are at least 55 years of age within six months of the taxpayer’s death.
  • Those who have owned and occupied the qualifying property for at least the last three years.
  • Those who have fire or casualty insurance coverage for the qualifying property in an amount not less than the amount of the taxes being deferred.
  • Those who do not owe outstanding property tax or special assessments.

How much will it cost?

  • 6% simple interest per year payable upon death, or at the time the home is transferred to a new owner or sooner, if the participant chooses to pay off the senior-deferral loan.

Second Installment Cook County Property Tax Bills Delayed

1024 683 Gayle Curcio

Northfield Township Assessor Alida E. Nally, CIAO, wants to inform residents that Cook County second installment property tax bills will be delayed. The projected timeline for these bills to be mailed and paid is late Fall 2022. Property taxes in Cook County are collected one year in arrears. Tax bills are mailed in installments twice a year.

First installment 2021 tax bills were mailed late January and were due March 1, 2022. The first installment tax amount is 55% of the previous year’s total taxes. Second installment tax bills are normally mailed by the first of July and due on the first business day of August. Delays in the issuance of property tax bills are being attributed to the implementation of a new integrated property tax management system in Cook County.

It is important to note that the delay in 2021 second installment tax bills means homeowners (or their escrow) will have to be prepared to pay this 2021 property tax bill late Fall 2022 and be prepared shortly after to pay their first installment 2022 bills in March 2023. Before the treasurer’s office can print and mail the second installment bills, the state, county and local agencies must issue data of assessment appeals, the state equalization factor, exemptions and the local tax rates.
