Homestead Exemption
$10,000 off EAV in Cook County; $6,000 off EAV elsewhere. If you own and live in your home as your primary residence, file for this exemption with your county assessor. It's free, usually a one-time application, and provides immediate savings. See our homestead exemption guide for more details.
Senior Property Tax Benefits
$8,000 Senior Citizens Homestead Exemption. Senior Citizens Assessment Freeze (income under $65,000) locks EAV.
If you're approaching age 65, plan ahead. File as soon as you're eligible. Every year you delay is a year of savings lost. See our senior property tax exemption guide for national context.
Assessment Freeze Programs
Yes - Senior Citizens Assessment Freeze locks EAV at the year you qualify. Requires annual renewal. Income limit $65,000.
Assessment freezes become more valuable every year as surrounding property values increase. The sooner you lock in your base, the more you save over time. See our state-by-state freeze guide.
Property Tax Deferral
Yes - Senior Citizens Real Estate Tax Deferral for 65+ with income under $55,000. 6% interest. Lien on property.
Deferral is ideal for homeowners who are house-rich but cash-poor. You keep your home and defer payments until you sell or transfer the property. For more information, see our senior deferral guide.
Veteran and Disability Exemptions
Returning veterans exemption ($5,000 for 2 years). Disabled veterans exemption based on disability percentage up to full exemption. Standard homestead exemption available.
For a complete breakdown of veteran benefits, see our disabled veteran exemption guide and 100% disabled veteran guide.
Income-Based Relief
Limited income-based programs through the Senior Citizens Assessment Freeze.
Income-based programs are among the most underused property tax benefits. Check eligibility even if you think your income is too high. The thresholds are often more generous than expected. See our circuit breaker guide.
What Makes Illinois Unique
Cook County triennial reassessment causes dramatic swings. Equalized assessed value (EAV) is about 1/3 of market value. Multiple exemptions stackable. Longtime Homeowner Exemption limits assessment increases for qualifying owners. Appeal to Cook County Assessor, then Board of Review.
How to Appeal Your Illinois Assessment
Appeals in Illinois go to the County Board of Review (Cook County BOR or PTAB). The process generally involves:
- Reviewing your assessment notice when it arrives
- Comparing your assessed value to comparable sales and neighboring assessments
- Filing an appeal by the deadline (check your notice for the specific date)
- Presenting evidence at a hearing or submitting it in writing
The most effective evidence includes 3 to 5 comparable sales showing your assessed value is too high, plus any property record errors you've found. See our error-checking guide and negotiation tips.
Stack Your Savings
The biggest savings come from combining multiple strategies: claim every exemption, correct any errors, apply for income-based programs, and appeal if your assessment is too high. Most Illinois homeowners can save $500 to $3,000 or more per year by being proactive.
