Manhattan Township Assessor 2024 Assessments now uploaded.

Welcome and I hope you find the information you are looking for from the Assessor's Office.  Since this data is subject to change during a calendar year it is only considered reference information.  Also due to the complexity of commercial and industrial parcels because of the differences in their use, plus some have multiple buildings, the web property record is only a summary of the data for what is viewed in the photo and sketch. Regarding any questions of accuracy or additional information for commercial, farm, industrial, or residential parcels, please Contact the Manhattan Township Assessor's Office.

Regarding Property Assessments and Property Taxes
Property taxes are paid in arrears, taxes paid in the current year are based on the prior year assessed values.  On this site the prior years assessed value will be displayed from January 1st of each new year thru July of the new year.  The current year assessed values will be displayed from August 1st of the new year thru December 31st the end of the current year.  Current year assessment changes are not final until after the Will County Board of Review closes at the end of the current year.

Illinois Property Tax Bill Basis
Illinois Property tax bill is always based on the prior year total assessed value. To estimate the tax bill first subtract any exemptions you are receiving from the total assessed value. Then multiply the result by the most current tax rate shown on the Property Record Card that is not zero. General Homestead Exemption amount = 6,000 a regular Senior Exemption = 5,000 must be age 65 or greater to receive the Regular Senior. Other exemptions:

  • Senior Freeze (household income must be under $65,000 per year plus age 65 and over).
  • Home Improvement Exemption (is a 4-year exemption if you add a qualifying improvement to your primary residence that adds to the building assessment).  
  • Disabled Person or Disabled Veteran.  See www.willcountysoa.com for all exemptions.

Exemption and Tax Bill Information
The assessor's office does not log a parcel's total exemption amount; see www.willcountysoa.com for Exemption and Tax Bill information.

Will County Web Search: enter the PIN starting with the Manhattan County Code 14.  Example 14 12 01 100 001 0000.  Click "Search" on the next page that appears click on the parcel ID (PIN) then click Will County Treasurer to view information.  Below is a sample tax bill calculation. 

Total Assessed Value = 120,000, and tax rate = .103267 or 10.3267 per 100 of total assessed value.
Example 1: 120,000 - 6000 = 114,000 x .103267 = $11,772.44
Example 2: 120,000 - 6000 = 114,000 / 100 = 1,140 x 10.3267 = $11,772.44
