Illinois Property Tax Exemptions 2026: Homestead, Senior, Veteran & Disability

Illinois (IL) homeowners have several ways to legally reduce their property tax bill — homestead reductions, senior credits, veteran exemptions, and disability programs. This page lists every Illinois property tax exemption available in 2026, who qualifies, dollar amounts, and how to apply.

The Illinois Exemption Stack — What Every Homeowner Should Claim

General Homestead Exemption (GHE)

Reduces equalized assessed value (EAV) by up to $6,000 for Illinois residents who own and occupy the property as their principal residence. In Cook County, the reduction is $10,000 of EAV. Automatic on most parcels but can lapse when ownership changes — verify on your tax bill.

Senior Citizen Homestead Exemption

An additional $5,000 EAV reduction for homeowners age 65 or older who occupy the home as their principal residence. Apply with the county assessor; in Cook County the application renews automatically once filed.

Senior Freeze Exemption (Senior Citizens Assessment Freeze Homestead Exemption)

For homeowners age 65+ with total household income below the statutory threshold, the Senior Freeze fixes the EAV at the base-year level — future reassessments do not raise the taxable base. The household income limit is:

• Tax year 2025 (payable 2026): $65,000
• Tax year 2026 (payable 2027): $75,000 (raised by recent legislation)

The Senior Freeze is the single highest-value senior exemption in Illinois. In a rising-value market, the tax savings compound dramatically. Apply annually; Cook County applications for tax year 2025 open March 9, 2026.

Homestead Exemption for Persons with Disabilities

Reduces EAV by $2,000 for homeowners determined to have a qualifying disability under federal standards.

Veterans with Disabilities Exemption

Sliding scale based on VA service-connected disability rating:

• 30% to 49% disability: $2,500 EAV reduction
• 50% to 69% disability: $5,000 EAV reduction
• 70%+ disability or 100% total and permanent: full property tax exemption on the primary residence

Returning Veterans Homestead Exemption

$5,000 EAV reduction for the tax year in which a qualifying veteran returns from active duty in an armed conflict involving U.S. armed forces.

Long-Time Occupant Homestead Exemption (Cook County only)

Automatic cap on the growth of EAV for homeowners who have lived in the home for 10+ years, with income limits that vary annually.

PTELL: What It Does and Doesn't Cap

The Property Tax Extension Limitation Law (PTELL) limits how fast taxing districts can extend (collect) property tax revenue. It does not cap:

• Individual tax bills (your bill can rise substantially if your EAV grew faster than the district average)
• Individual assessed values
• Home-rule municipalities (Chicago, most large Illinois cities) — which are exempt from PTELL

What PTELL does

For covered taxing districts, the aggregate property tax extension can grow year-over-year by only the inflation factor (2.9% for 2026) plus an adjustment for new construction and annexations. Voters may approve additional levies at referendum.

Practical effect on homeowners

If your county's total assessed value grew 8 percent but PTELL limits the extension to 2.9 percent, the effective tax rate is rolled back so the total revenue stays within the cap. Individual homeowners whose property value grew faster than the county average pay more; those whose property grew slower pay less. PTELL cuts the aggregate, not individual bills.

Frequently Asked Questions

How do I qualify for the Illinois Senior Freeze Exemption?

Homeowners age 65 or older who own and occupy the home as their principal residence, with total household income below the statutory threshold ($65,000 for tax year 2025, $75,000 for tax year 2026). The exemption freezes the equalized assessed value at the base-year level. Apply annually with your county assessor — Cook County 2025 applications open March 9, 2026.

How does the 100% Disabled Veterans exemption work in Illinois?

Veterans with a 100 percent service-connected disability rating (or their surviving spouses) receive a full exemption from property tax on their primary residence. Veterans with 70-99% disability qualify for the same full exemption. Lower disability ratings produce smaller EAV reductions on a sliding scale ($2,500 for 30-49%, $5,000 for 50-69%). Apply with your county assessor providing VA disability documentation.
