Divisions and Incentives Filing Fees_Division

Fee Structure Information

In an effort to generate revenue, the Cook County Board recently approved a new fee plan requiring the Cook County Assessor's Office to begin charging fees for a number of services. The CCAO has begun charging for the following:

Certified Documentation$1.00
Incentive Application Filing$1,000.00
Amendment to Original Incentive Application$100.00
Division/Consolidation Petition - 3 Tracts$100.00
....... each additional tract$20.00
Division/Consolidation Petition filed between September 1st and November 1st - 3 Tracts$300.00
....... each additional tract$60.00
Amendment to Divide/Consolidation Petition$50.00

Checks should be made payable to: COOK COUNTY ASSESSOR'S OFFICE

All fees associated with the above-referenced items are non-refundable filing fees. Acceptance of a filing fee by the Cook County Assessor's Office does not guarantee that the office will grant the requested action related to the filing fee. It is the responsibility of the submitter or submitter's agent to provide all necessary materials. 

There is a $25 processing fee for each check that is returned by the submitter's bank for any reason. A returned check must be redeemed with cash, certified funds, electronic payment, or money order. The returned check service charge and the original amount due must be paid before the Assessor’s Office will process applications or petitions. All Division Filing Fees must be paid by credit card online, check, money orders, cashier's checks, cash or cash equivalents.
