If you own property in Oak Lawn, you're in Worth Township — one of the Cook County townships currently open for the 2026 reassessment cycle. That means right now is your best window to appeal your property tax assessment and potentially save hundreds or thousands of dollars per year.
Cook County reassesses properties on a 3-year cycle divided by district. Worth Township is part of the south district, which is being reassessed in 2026. When your township is in a reassessment year, the Cook County Assessor's Office is actively reviewing and updating property values — and this is when appeals carry the most weight.
Worth Township includes: Oak Lawn, Chicago Ridge, Worth, Palos Hills, Alsip, Hometown, Bridgeview, Justice, Hickory Hills, Burbank.
The Assessor appeal window for Worth Township is open now, with a closing deadline in spring 2026. Don't wait.
Cook County has one of the highest effective property tax rates in the country, and over-assessment is widespread — especially in the south suburbs. Assessments are supposed to reflect 10% of your property's fair market value.
If your assessed value implies a market value significantly higher than what comparable homes in Oak Lawn are actually selling for, you're over-assessed and paying more than your fair share.
The only way to fix it is to appeal.
Step 1: Get your current assessed value. Look at your most recent tax bill or search your address at cookcountyassessor.com.
Step 2: Find comparable sales. Recent sales of similar homes in Oak Lawn or nearby Worth Township communities are your strongest evidence. If those homes sold for less than your assessment implies, you have grounds to appeal.
Step 3: File your appeal with the Assessor's Office. Submit your evidence (called Rule 15 comparable sales) during the open window. The Assessor reviews it and issues a decision.
Step 4: If needed, appeal to the Board of Review. If the Assessor doesn't reduce your assessment enough — or denies your appeal — you have a second chance at the Cook County Board of Review.
Savings vary based on how over-assessed your property is and Oak Lawn's current tax rate. But homeowners in Worth Township and surrounding areas who appeal successfully typically see reductions of $500–$2,000 per year. Over a 3-year period before the next reassessment, that's real money.
Normally this process means spending hours pulling comparable sales, formatting evidence, and filling out Assessor forms — or paying a tax attorney $300–500 to do it for you.
