What Are Evanston Property Taxes? Exemptions, Appeals & Due Dates

Property taxes in Evanston are set not by the city alone but by roughly a dozen overlapping taxing bodies, with the two local school districts driving more than half of every bill. The City of Evanston itself accounts for about 16% of the typical bill.¹ Add in the Cook County equalization multiplier, which roughly triples your assessed value before any rate is applied, and the composite rate on an Evanston home climbs above 7%. A $400,000 home with only the basic Homeowner Exemption owes somewhere in the range of $7,300 to $8,400 per year.

Where Your Tax Dollars Go

Your bill is the sum of separate levies from independent taxing districts. For the 2023 tax year (paid in 2024), the major rates looked like this:

Evanston Elementary School District 65: 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%

Smaller levies from the Evanston Public Library, park district, and Oakton Community College push the composite rate above 7%.¹ District 65 and District 202 are the biggest drivers, so when either school district raises its levy, every residential bill in the township feels it.

How Your Bill Is Calculated

Four numbers combine to produce what you owe: fair market value, assessed value, equalized assessed value, and the composite tax rate. Exemptions get subtracted along the way.

The Cook County Assessor sets the fair market value for every parcel on a triennial cycle. Evanston sits in the north suburban group, most recently reassessed in 2025, with notices mailed that April.² Those 2025 values will drive the bills arriving in 2026.

Residential property in Cook County is assessed at 10% of fair market value.³ That is only the starting point. Illinois law requires every county to assess property at 33⅓% of market value, so the Department of Revenue applies an equalization multiplier to Cook County to bridge the gap. The final multiplier for the 2024 tax year was 3.0355.⁴ The tentative multiplier for the 2025 tax year is 2.8683.⁵

Here is the sequence for a $400,000 Evanston home using the 2025 tentative multiplier:

Fair market value: $400,000
Assessed value (10%): $40,000³
Equalized assessed value ($40,000 × 2.8683): $114,732⁵
Minus the $10,000 Homeowner Exemption: $104,732 taxable EAV⁶
Multiplied by the composite rate (above 7%)

This is why the equalized assessed value, not the assessed value, is the number that matters, and why every exemption dollar reduces EAV rather than the tax bill directly.

Exemptions That Lower Your Bill

Exemptions reduce your taxable EAV before the rate applies. You have to own and occupy the property as your primary residence to qualify for any of them. For the 2025 tax year, exemption applications are due by May 15, 2026.⁷

Homeowner Exemption

The baseline exemption cuts up to $10,000 from your EAV for an owner-occupied Cook County home.⁶ After the first application it renews automatically.⁷ If you bought recently and never filed, you are overpaying until you do.

Senior Homestead Exemption

Homeowners 65 or older receive an additional $8,000 EAV reduction stacked on top of the Homeowner Exemption.⁸ It renews automatically after the first filing.⁷

Senior Citizens Assessment Freeze

The Senior Freeze does not freeze your bill. It freezes the EAV at the level when you first qualified, so rising values stop pushing your taxable base up. You must be 65 or older, have household income of $75,000 or less, and have owned and lived in the home for at least three years.⁹ This one requires re-filing every year because the Assessor has to verify income.⁷

Persons with Disabilities Exemption

Homeowners with a qualifying disability receive a $2,000 EAV reduction.¹⁰ Recent state legislation made this one auto-renewing.⁷

Veterans Exemptions

The Returning Veterans Exemption gives a $5,000 EAV reduction for two consecutive tax years after a veteran returns from active duty in an armed conflict.⁶ The Veterans with Disabilities Exemption scales with disability rating; veterans rated 70% or more disabled receive an EAV reduction of up to $250,000, which often zeroes out the tax bill entirely.¹¹ Both require annual filing.⁷

Longtime Homeowner Exemption

If you have owned and occupied your Evanston home for at least 10 consecutive years and household income is $100,000 or less, you may qualify. Households earning $75,000 or less need to show a 7% annual EAV increase; households between $75,001 and $100,000 need to show a 10% annual increase.¹²

Senior Citizens Real Estate Tax Deferral

This state program lets qualifying seniors postpone paying part of their property taxes. The deferred amount becomes a lien repaid when the home is sold, so it functions as a loan from the state rather than a reduction.⁶

Appealing Your Assessment

If your 2025 reassessment notice came in high, you have three levels of appeal. The first two are free.

Cook County Assessor

Every appeal starts with your 14-digit Property Index Number, printed on your tax bill, deed, and assessment notice; you can also look it up on the Cook County Property Tax Portal.¹³¹⁴ The strongest appeals use comparable properties to show your home is assessed higher than similar homes nearby. The Assessor’s online appeal tool helps you find and select comparables, and a paper form is available if you prefer mail.¹⁵¹⁶ A recent appraisal or documentation of structural problems can also support your case.

You generally have 30 days from the date on your reassessment notice to file. The exact deadline varies by township and is listed on the notice and on the Assessor’s calendar.¹⁷ Miss it, and this first level of review closes.

Cook County Board of Review

A denial or a disappointing reduction at the Assessor’s level is not the end. The Board of Review is a separate elected body that opens its own filing window for each township after the Assessor finishes.¹⁸ You can file online through its portal or by mail.¹⁹ Many successful reductions happen at this stage, so skipping it because the Assessor already said no is a mistake.

Illinois Property Tax Appeal Board

If the Board of Review also rules against you, the Illinois Property Tax Appeal Board is the state-level forum.²⁰ You have 30 days from the Board of Review’s decision to file.²¹ PTAB rules only on whether the assessed value is correct; it cannot touch tax rates, exemptions, or the total bill. Appeals filed through an attorney must be submitted electronically.

When Bills Are Due

Cook County bills in two installments. The first installment is due in early March and is exactly 55% of the prior year’s total bill.³ It is essentially an advance payment, because final rates and exemptions for the current year have not been calculated yet.

The second installment reflects the actual rates, equalization factor, and any exemptions or successful appeals, and it trues up the difference. The statutory target is late summer, but Cook County has frequently pushed second-installment bills into the fall or December. The tax year 2024 second installment was due December 15, 2025.²² Check the Treasurer’s website each year rather than assuming a fixed date.

You can pay online through the Treasurer’s portal with an electronic check, mail a payment with the bill stub, or pay in person at participating bank branches during the collection period.

What Happens If You Pay Late

Missing a due date triggers a monthly interest penalty of 0.75% on the unpaid balance, or 9% annually.²³ That rate, cut from 1.5% per month in 2023, applies to any delinquent balance from tax year 2023 forward.

The real risk comes later. Properties with taxes delinquent for three or more years become eligible for Cook County’s biennial Scavenger Sale, where the county sells the tax debt to recover unpaid revenue. If the debt is not redeemed within the statutory redemption period, the owner can lose the home. A month or two late is expensive; years of unpaid taxes put ownership itself on the line.
