What’s Happening

Second Installment Tax Bills To Be Mailed At Least One Month Late

When Cook County’s second installment property tax bills are sent out on time, tax bills hit mailboxes in late June and are due around August 1. This year, however, the mailing and due dates for tax bills will be delayed by at least one month, according to Northfield Township Assessor Alida Nally. This means that second installment tax bills will be due no earlier than September 1, and the due date could be later.

For decades, the county agencies involved in preparing property tax bills have been using a 1980’s-era mainframe computer system. The county has been phasing out the old mainframe for the last few years, but 2025 marks the first year in which the old system will be phased out completely. This year’s tax bills will be calculated in their entirety under the new system.

The problems associated with the final transition to the new system are the reason for the delay in this year’s tax bills. “Although we are experiencing growing pains with the new system this year, I am hopeful that the system will make it easier to issue tax bills on time in future years,” Nally said.

Illinois Expands Property Tax Breaks for Veterans to Include World War II Vets
From the Cook County Treasurer’s Office:

Illinois lawmakers have enacted significant changes to property tax exemptions benefiting veterans, including a landmark provision for those who served during World War II. These amendments, effective for the 2024 tax year, underscore our commitment to supporting our veteran community.

The newly expanded legislation, Public Act 103-0596, amends the Illinois Property Tax Code to make veterans who served during World War II exempt from paying property taxes on their primary residences, regardless of their disability status. The new law also extends the benefit to unmarried, surviving spouses of World War II veterans, certified by the U.S. Department of Veterans Affairs for compensation due to service-connected death.

Exemptions

The Cook County Assessor’s Office administers property tax exemptions that may contribute to lowering your property tax bill. These savings are reflected on the second-installment property tax bills.

For example, property tax savings for a Homeowner Exemption is calculated by multiplying the Homeowner Exemption amount of $10,000 by your annual local tax rate and a Senior Exemption by multiplying $8,000 by your local annual tax rate. These savings can add up!

If you need additional assistance, my office is here to help.

Appeals

An appeal is intended to correct the accuracy of your property’s assessment. An increase (or decrease) in your home’s assessment does not lead to the same increase (or decrease) in your property taxes.

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 years for assessment purposes. This new assessed value along with exemptions helps determine your share of property taxes owed.

Property owners have two annual 30-day windows to appeal their assessed value. Once with the Cook County Assessor, cookcountyassessor.com/appeals and then followed by the Cook County Board of Review, cookcountyboardofreview.com/appeals.

Further relief may be sought through the Property Tax Appeal Board (PTAB) or the courts.

Here at Northfield Township, we can help review your assessment to be sure it is equitable and file an appeal if helpful.
