The Evanston, IL property tax rate is roughly 8.026 per $100 of equalized assessed value for tax year 2023 (billed in 2024).1City of Evanston. Property Tax Bill Explanation That composite figure is the sum of about a dozen overlapping taxing districts, not a number set by the city alone. More than two-thirds of it funds the local schools. What you actually owe depends on your property’s assessed value, the state equalization factor, and the exemptions you qualify for, so two homes on the same block can produce very different bills.
Where the 8.026 Rate Comes From
Every Evanston parcel sits inside multiple taxing bodies, and each one adds its own levy. For tax year 2023, the pieces look like this: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 lines total 8.026. A parcel inside the Ridgeville Park District pays another 0.106, and one inside the Lighthouse Park District pays another 0.072, pushing the composite rate slightly higher for those homes.1City of Evanston. Property Tax Bill Explanation
The schools dominate. Districts 65 and 202 together account for about two-thirds of the rate. The City of Evanston itself is roughly 16 percent. Everything else, from the library fund to mosquito abatement, fills the rest. When a school budget vote or a library levy comes up, that is where the number actually moves.
How Your Tax Bill Is Calculated
Three numbers decide what you pay: your property’s assessed value, the state equalization factor, and your exemptions.
Assessed Value
The Cook County Assessor assigns every residential property an assessed value equal to 10 percent of its estimated fair market value.2Cook County Assessor’s Office. Classifications of Real Property A home the Assessor pegs at $400,000 in market value starts with an assessed value of $40,000.
The State Equalization Factor
The Illinois Department of Revenue publishes an equalization factor each year to align Cook County assessments with the rest of the state. The final multiplier for tax year 2024 is 3.0355.3Illinois Department of Revenue. 2024 Cook County Final Multiplier Announced You multiply your assessed value by the factor to get your Equalized Assessed Value, or EAV. On the $40,000 example, that produces an EAV of $121,420. The multiplier changes every year, and when it rises your EAV rises with it even if the Assessor’s view of your market value held steady. County clerks are required by the Illinois Property Tax Code to apply the certified factor to every assessment.4Illinois General Assembly. 35 ILCS 200, Section 18-40
The Formula
Subtract your exemptions from the EAV, then multiply by the composite rate:
(EAV − Exemptions) × Tax Rate = Tax Bill
Carrying the example forward with the standard $10,000 Homeowner Exemption, taxable EAV drops to $111,420. Applied to the 8.026 percent composite rate, the estimated annual bill is about $8,943. The Assessor’s Office publishes each property’s assessment data, and the Cook County Clerk maintains the rates, so you can run the math on your own parcel before the bill arrives.5Cook County Assessor’s Office. Your Assessment Notice and Tax Bill
Exemptions That Reduce the Bill
Exemptions shrink the EAV that gets taxed, so they lower your bill without touching the rate. Some require an initial application with the Cook County Assessor’s Office and will not apply on their own.
General Homestead Exemption
Any owner-occupant of a primary residence in Cook County qualifies for a reduction of up to $10,000 in EAV.6Cook County Treasurer’s Office. Homeowner Exemption At Evanston’s rate, that is roughly $800 off a year. File once, and it renews automatically as long as you keep living there.
Senior Citizen Homestead Exemption
Owner-occupants 65 and older can claim an additional $8,000 reduction in EAV.7Cook County Assessor’s Office. Senior Exemption It stacks with the General Homestead Exemption, so a qualifying senior can see up to $18,000 removed from taxable EAV.8Illinois General Assembly. 35 ILCS 200, 15-170
Senior Citizen Assessment Freeze
This exemption freezes your EAV at the level from the year you first qualified. Eligibility requires that you be 65 or older, own and occupy the home as your principal residence, and have a total household income of $65,000 or less.9Illinois Department of Revenue. Property Tax Relief – Homestead Exemptions The freeze locks your assessment, not your bill: the rate can still move. You must reapply every year to recertify income.
Persons with Disabilities Exemption
Homeowners with a qualifying disability 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 each year.
Veterans with Disabilities Exemption
Veterans with a service-connected disability certified by the U.S. Department of Veterans Affairs get 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 at 70 percent or higher on a typical Evanston home would owe little to no property tax.
Payment Schedule and Late Penalties
Cook County sends tax bills in two installments. The first is exactly 55 percent of the prior year’s total and acts as a placeholder while current-year assessments and rates are finalized.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 arrives in the summer, reflects your actual bill after new rates and exemptions, and is typically due by August 1.
You can pay through the Treasurer’s online portal, by mail, or in person at authorized bank locations with the original bill stub. Unpaid taxes accrue interest at 0.75 percent per month for tax year 2023 and later, under Illinois law.11Illinois General Assembly. 35 ILCS 200, Section 21-15 That is 9 percent annualized, and if delinquency continues the unpaid amount can eventually be offered at Cook County’s Annual Tax Sale, which puts a lien on your property and starts a redemption clock.12Cook County Treasurer’s Office.

Appealing Your Assessment
If the Assessor’s value looks higher than what your home would actually sell for, the appeal process is the most effective way to lower your bill, and it costs nothing to file yourself.
Appeal to the Cook County Assessor
Start with an appeal directly to the Assessor’s Office. Each township opens on a rolling schedule, and you have to file before your township’s deadline.13Cook County Assessor’s Office. Assessment and Appeal Calendar You can submit online. The strongest cases include comparable sales showing that similar homes nearby sold for less than your assessment implies.14Cook County Assessor’s Office. File an Appeal Online
Appeal to the Board of Review
If the Assessor’s answer does not resolve the issue, take it to the Cook County Board of Review, an independent body that reviews assessments after the Assessor finalizes them. The Board opens its own filing window per township, and you can submit new evidence at this stage. Some owners hire attorneys who work on contingency, typically 25 to 50 percent of the first year’s tax savings. That can pencil out for a large reduction, but a modest adjustment is well within reach on your own.
