Park Ridge property tax bills run at an effective rate of about 2.5% of a home’s market value, which comes to roughly $10,000 a year on a $400,000 house. The exact figure depends on which taxing districts cover your parcel, your home’s equalized assessed value, and the exemptions on file with the Cook County Assessor. Knowing how each piece is built is the best way to confirm the bill is right and to spot a chance to lower it.
What Makes Up the Bill
No single office sets your tax. More than a dozen taxing districts each adopt a budget and file a levy request with the Cook County Clerk, who divides each request by the total taxable value inside that district to produce a rate per $100 of equalized assessed value.1Cook County Clerk. Tax Extension and Rates The rates that apply to your parcel stack into one composite rate, and that composite is what hits your bill.
The two schools do most of the work: Park Ridge–Niles School District 64 and Maine Township High School District 207 together account for the majority of a typical residential bill. The City of Park Ridge, the Park Ridge Park District (about 5.85% of a typical bill), and the Park Ridge Public Library make up most of the rest.2Park Ridge Park District. Financials Because the district mix shifts slightly across town, two neighbors on opposite sides of a boundary line can carry different composite rates.
How Your Taxable Value Is Calculated
Your bill is not applied to the full market value of your home. Cook County assesses residential property at 10% of estimated fair market value.3Cook County Assessor’s Office. Classifications of Real Property A home the Assessor values at $400,000 starts with an assessed value of $40,000. The Assessor reviews values on a triennial cycle, so your assessment stays put between reassessment years unless you make improvements or win an appeal.4Cook County Assessor’s Office.

The Illinois Department of Revenue then applies an equalization factor to bring Cook County into line with the rest of the state. For the 2025 tax year, the tentative multiplier is 2.8683.5Illinois Department of Revenue. 2025 Cook County Tentative Multiplier Announced Multiply assessed value by the factor to get Equalized Assessed Value (EAV). Exemptions come off the EAV, and the composite rate is applied to what remains.
A Sample Calculation
For a $400,000 home with the standard homeowner exemption:
- Market value: $400,000
- Assessed value (10%): $40,000
- EAV after equalization (× 2.8683): $114,732
- EAV after homeowner exemption (− $10,000): $104,732
- Tax bill: $104,732 × your composite rate per $100 of EAV
The composite rate changes every year and varies by tax code within Park Ridge. You can look up the current rate for your parcel on the Cook County Clerk’s tax rate report or read it off your second-installment bill.
Exemptions That Lower the Bill
Exemptions reduce EAV before the rate is applied, so the dollar savings show up directly. You apply through the Cook County Assessor’s Office, and most exemptions need annual renewal or re-certification.
General Homeowner Exemption
Owner-occupants of a primary residence qualify for a reduction of up to $10,000 in EAV.6Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions, PTELL, and Senior Citizens Real Estate Tax Deferral Program Once granted, it renews automatically while you remain the owner-occupant, but confirm each year that it is still showing on your bill.
Senior Citizen Homestead Exemption
Homeowners aged 65 or older get an additional $8,000 reduction in EAV on top of the general homeowner exemption.7Cook County Assessor’s Office. Senior Exemption A qualifying senior can therefore cut EAV by as much as $18,000.
Senior Freeze Exemption
The Senior Freeze is a separate benefit and often confused with the one above. It locks your EAV at its current level so future reassessments don’t push it up. It does not freeze the bill itself, because rates can still move. You must be 65 or older with a total household income of $65,000 or less, and you must reapply every year.8Cook County Assessor’s Office. Low-Income Senior Freeze Exemption
Persons with Disabilities Exemption
Homeowners with a qualifying disability receive a $2,000 annual EAV reduction.6Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions, PTELL, and Senior Citizens Real Estate Tax Deferral Program Acceptable proof includes a Class 2 Illinois disability identification card, a Social Security Administration disability award letter, or a physician’s statement on Form PTAX-343-A.9Illinois Department of Revenue. PTAX-343-A – Physician’s Statement for the Homestead Exemption for Persons with Disabilities
Veterans with Disabilities Exemption
Disabled veterans receive tiered relief based on their VA-certified rating:6Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions, PTELL, and Senior Citizens Real Estate Tax Deferral Program
- 30%–49% disability: $2,500 reduction in EAV
- 50%–69% disability: $5,000 reduction in EAV
- 70% or higher: the first $250,000 of the home’s EAV is exempt from taxation
Veterans in specially adapted housing purchased with federal funds may qualify for up to a $100,000 reduction in assessed value instead. The standard veterans exemption cannot be combined with the specially adapted housing exemption or the persons with disabilities exemption in the same tax year.
Appealing Your Assessment
If the Assessor overvalued your home, you have two free levels of appeal, and you don’t need a lawyer for either one.
Appeal to the Assessor’s Office
When Maine Township (which covers Park Ridge) opens for appeals on the schedule the Assessor’s Office posts, you can file online. You’ll need your Property Index Number (PIN), which appears on your assessment notice and tax bill.10Cook County Assessor’s Office. File an Appeal Online The strongest evidence is recent comparable sales of similar homes nearby that sold for less than the Assessor’s estimated market value. Photos of deferred maintenance, a recent appraisal, or repair estimates help as well. A bare list of addresses and prices usually falls short; you need to show why each comparable supports a lower value for your home.
Appeal to the Board of Review
If the Assessor denies the appeal or the reduction is too small, you can take it to the Cook County Board of Review, a separate body that conducts its own review. File through the Board’s online portal, select “Property Over Assessment,” enter your PIN, and upload your evidence.11Cook County Board of Review. Portal Guide – Property Owners You can request an in-person hearing. The Board publishes its own township deadlines each year, so check the site early; missing the window means waiting until the next reassessment cycle.
Payment Deadlines
Cook County splits the annual bill in two. The first installment is set by law at 55% of the previous year’s total tax; the second installment covers the balance once new rates, assessments, and exemptions are applied.12Cook County Assessor’s Office. Your Assessment Notice and Tax Bill The first installment is normally due March 1, though the legislature occasionally shifts the date; for the 2025 tax year, the statutory deadline moved to April 1, 2026.13Illinois General Assembly. 35 ILCS 200 – Property Tax Code The second installment is due August 1.
You can pay online from a checking or savings account at no charge, or by credit card for a 2.1% convenience fee. Payments are also accepted by mail with the coupon from your bill, or in person at Chase Bank branches in Illinois and participating community banks.14Cook County Treasurer.

What Happens If You Pay Late
For the 2023 tax year and beyond, unpaid Cook County property taxes accrue interest at 0.75% per month, or 9% annually.13Illinois General Assembly. 35 ILCS 200 – Property Tax Code Interest begins the day after the due date, and any partial month counts as a full month.
If taxes remain unpaid into the following year, the debt is offered at the Cook County Annual Tax Sale, where investors bid on the right to collect what’s owed plus interest. The Treasurer’s Office anticipates holding the next Annual Tax Sale in December 2026. Properties delinquent for three or more years become eligible for the Scavenger Sale, where the debt is auctioned with a minimum opening bid of $250.15Cook County Treasurer. Annual Tax Sale Neither sale transfers ownership of the home right away, but both start a legal process that can end in losing the property if the debt isn’t redeemed.
