The property tax rate in Evanston, IL comes out to roughly 8.026 per $100 of equalized assessed value for tax year 2023, paid in 2024.1City of Evanston. Property Tax Bill Explanation That figure is a composite. No single government sets it. About a dozen overlapping taxing districts each levy their own share, and more than two-thirds of a typical Evanston bill funds the schools. What you actually pay depends on your parcel’s assessed value, the annual state equalization factor, and the exemptions you claim.
What Makes Up the Rate
Every Evanston property sits inside several taxing bodies at once. The individual rates for tax year 2023 are:1City of Evanston. Property Tax Bill Explanation
- School District 65 (elementary): 3.322
- Evanston Township High School District 202: 2.112
- City of Evanston: 1.269
- Cook County: 0.493
- Metropolitan Water Reclamation District: 0.345
- Oakton Community College District 535: 0.227
- Evanston Public Library Fund: 0.221
- City of Evanston General Assistance: 0.029
- North Shore Mosquito Abatement District: 0.008
Those add up to 8.026. Some parcels also fall inside the Ridgeville Park District (adding 0.106) or the Lighthouse Park District (adding 0.072), which nudges their composite rate higher.1City of Evanston. Property Tax Bill Explanation
The two school districts together account for roughly two-thirds of the total. The City of Evanston itself is about 16 percent. Everything else, from the library fund to mosquito abatement, fills the rest. When a school levy or library referendum shifts, your rate shifts with it.
How Your Bill Is Calculated
Three inputs determine the dollar figure: your assessed value, the state equalization factor, and your exemptions.
Assessed Value
The Cook County Assessor sets each property’s assessed value as a percentage of its estimated market value. Residential properties (Class 2) are assessed at 10 percent of market value; commercial properties are assessed at 25 percent.2Cook 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 State Equalization Factor
The Illinois Department of Revenue publishes an annual multiplier that brings Cook County assessments into line with the rest of the state. For tax year 2024, the final factor is 3.0355.3Illinois Department of Revenue. 2024 Cook County Final Multiplier Announced Multiply your assessed value by that factor to get your Equalized Assessed Value (EAV). The $40,000 example becomes an EAV of $121,420. The multiplier changes each year, and county clerks are required to apply whatever factor the Department certifies.4Illinois General Assembly. 35 ILCS 200, Section 18-40 A rising multiplier can lift your EAV even in a year when the Assessor didn’t touch your market value estimate.
The Formula
Once you know your EAV, the arithmetic is simple:
(EAV − Exemptions) × Tax Rate = Tax Bill
Continuing the example, a homeowner claiming the standard $10,000 Homeowner Exemption has a taxable EAV of $111,420. Multiplied by 8.026 percent, the estimated annual bill is about $8,943. Assessment data is on the Cook County Assessor’s site and the applicable rates are maintained by the Cook County Clerk, so you can run the numbers before your bill arrives.5Cook County Assessor’s Office. Your Assessment Notice and Tax Bill
Exemptions That Lower Your Bill
Exemptions cut the EAV that gets taxed. They don’t change the rate, but they can meaningfully shrink what you owe. Some renew automatically once you file; others require a fresh application every year.
General Homestead Exemption
Any owner who occupies the property as a primary residence qualifies for a reduction of up to $10,000 in EAV.6Cook County Treasurer’s Office. Homeowner Exemption At the current composite rate, that’s roughly $800 off your annual bill. File once and it renews as long as you keep living there.
Senior Citizen Homestead Exemption
Homeowners 65 or older who occupy the home as a primary residence can claim an additional $8,000 EAV reduction.7Cook County Assessor’s Office. Senior Exemption It stacks with the General Homestead Exemption, so a qualifying senior can knock up to $18,000 off their taxable EAV.8Illinois General Assembly. 35 ILCS 200, Section 15-170
Senior Citizen Assessment Freeze
This one freezes your EAV at the level it hit in the year you first qualified. Eligibility requires being 65 or older, owning and occupying the home as your principal residence, and having a total household income of $65,000 or less.9Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions The freeze doesn’t lock in your tax bill, because the rate can still move. It just stops the assessment side from climbing. You must reapply each year to certify income.
Persons with Disabilities Exemption
A qualifying homeowner with a disability can receive a $2,000 annual reduction in EAV.9Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions Documentation such as a Social Security disability award letter or a physician’s certification is typically required, and the exemption must be renewed annually.
Veterans with Disabilities Exemption
Veterans with a service-connected disability certified by the U.S. Department of Veterans Affairs receive tiered relief:9Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions
- 30% to 49% disability: $2,500 EAV reduction
- 50% to 69% disability: $5,000 EAV reduction
- 70% or greater disability: full exemption on the first $250,000 of EAV
The top tier is substantial. A veteran with a 70-percent-or-higher rating in a typical Evanston home may owe little or no property tax. Separately, veterans whose homes were purchased or modified using federal disability funds can receive up to a $100,000 reduction in assessed value through the Specially-Adapted Housing exemption, though you can’t claim that and the Veterans with Disabilities Exemption on the same property in the same year.9Illinois Department of Revenue.

When Bills Are Due
Cook County bills property taxes in two installments. The first installment is exactly 55 percent of the prior year’s total and functions as a placeholder while the county finalizes current-year assessments and rates.5Cook County Assessor’s Office. Your Assessment Notice and Tax Bill For tax year 2025, the first installment is due April 1, 2026.10Cook County Treasurer’s Office. Important Dates The second installment lands in summer and reflects the actual figure after new rates and exemptions are applied. It’s typically due by August 1.
You can pay online through the Cook County Treasurer’s portal, by mail, or in person at authorized banks with your original bill stub. Miss a deadline and unpaid taxes accrue interest at 0.75 percent per month for tax year 2023 and after, which works out to 9 percent annually.11Illinois General Assembly. 35 ILCS 200, Section 21-15
Appealing Your Assessment
If your assessed value looks high relative to what your home would actually sell for, you can appeal. It’s the most direct way to lower your tax bill, and filing yourself costs nothing.
Appeal to the Assessor
Start with the Cook County Assessor’s Office. Each township opens for appeals on a rolling schedule, and you must file before your township’s deadline.12Cook County Assessor’s Office. Assessment and Appeal Calendar The Assessor takes online submissions. Strong appeals include comparable sales showing that similar homes nearby sold for less than what your assessment implies.13Cook County Assessor’s Office. File an Appeal Online
Appeal to the Board of Review
If the Assessor’s decision doesn’t fix the problem, take it to the Cook County Board of Review. This independent body reviews assessments after the Assessor has finalized them, and it opens its own filing window by township. You can submit new evidence, and many homeowners who were denied at the first stage succeed here. Some owners hire attorneys who work on contingency, typically charging 25 to 50 percent of the first year’s tax savings. That can be worth it for a large reduction; for modest ones, filing on your own is straightforward.
If You Don’t Pay
Cook County does not let unpaid property taxes sit. The 0.75 percent monthly interest starts the day after each installment’s due date.11Illinois General Assembly. 35 ILCS 200, Section 21-15 If the balance is still unpaid the following year, the county offers it at the Annual Tax Sale, where an investor pays your delinquent taxes and receives a lien on your property.14Cook County Treasurer’s Office. Annual Tax Sale
You don’t lose ownership at the sale. You enter a redemption period during which you can repay the buyer the taxes plus substantial additional interest to clear the lien. For residential properties with fewer than six units, the redemption period is two and a half years from the sale date, and the tax buyer can extend the final deadline up to three years.15Illinois General Assembly. 35 ILCS 200 – Redemption Period Miss that window and the buyer can petition the court for a deed. The penalties compound fast, and the tax sale process can eventually cost you the home.
