Illinois offers several property tax exemptions that can meaningfully reduce your annual bill. The General Homestead Exemption reduces your Equalized Assessed Value (EAV) by $10,000 in Cook County and $6,000 in all other counties — you must file an application once and renewal is typically automatic. Seniors (65+) can claim an additional $8,000 EAV reduction via the Senior Citizens Homestead Exemption. The Senior Citizens Assessment Freeze locks your EAV at the base year level if your household income is under $65,000. Disabled veterans receive additional exemptions ranging from $2,500 to 100% exemption depending on disability rating. All exemptions require owner-occupancy as a primary residence.

Frequently Asked Questions
How much is the Illinois General Homestead Exemption?
The General Homestead Exemption reduces your Equalized Assessed Value (EAV) by $10,000 in Cook County and $6,000 in all other Illinois counties. At a typical Cook County tax rate of 6.5% of EAV, this saves approximately $650/year in Cook County ($390 in other counties).
How do I apply for the Illinois homestead exemption?
You apply once with your county assessor's office after purchasing your home and establishing it as your primary residence. In Cook County, submit Form PTAX-340 (or apply online). Many counties now automatically apply the exemption after the first approval. You lose it if you sell, rent out the home, or it is no longer your primary residence.
What is the Illinois Senior Assessment Freeze?
The Senior Citizens Assessment Freeze Homestead Exemption freezes your property's EAV at the level when you first qualified, preventing tax increases as assessed values rise. Available to owners 65+ with household income under $65,000. You must reapply annually with your county assessor.
What exemption do disabled veterans get in Illinois?
Illinois veterans with service-connected disabilities receive: $2,500 EAV reduction (30-49% disability), $5,000 EAV (50-74%), $7,500 EAV (75-99%), and a complete 100% exemption for fully (100%) service-connected disabled veterans. Surviving spouses may also qualify.
Is the Illinois homestead exemption automatic after I apply?
In Cook County, the exemption is generally automatic once you've applied and been approved, provided you continue to meet the primary residence requirement. Most collar counties also auto-renew. However, you should verify your exemptions annually on your tax bill, as errors do occur and must be corrected through the assessor's office.
