Office of the Assessor

We MovED!

The Vernon Township Assessor’s office HAs movED to the Vernon Township Community Services Building at 2900 N. Main Street, Buffalo Grove. The building is located immediately South of THE FORMER office in the Vernon Township Administration Building.

The Vernon Township Assessor is your liaison to the Chief County Assessment Office. The Township Assessor is an elected position (4-year terms). The assessor must be certified by the State and meet continuing education requirements. 

The job of the assessor is to value all taxable parcels of property within the township in a uniform manner, so that all properties are valued at the same approximate assessment level. This creates a fair share spread of the real estate tax burden throughout the township. The assessor has no say or control of the tax monies requested by any given taxing district.


Annual exemption renewals for the Senior Citizen Assessment Freeze, the Homestead Exemption for Persons with Disabilities and the Veterans with Disabilities Exemption can be applied for online through the Chief County Assessment Office's SmartFile E-Filing Portal. Please note that the General Homestead Exemption and Senior Citizen Homestead Exemption do not have to be renewed annually. The Vernon Township Assessor’s Office will help you file renewals online. 

Please contact my office if you have any questions: Vernon Township Assessor - 847-634-4602 or by email at

Senior Citizen Assessment Freeze Information

Property owners age 65 and older who have a total household income of $65,000 or less are encouraged to apply for the Senior Citizen’s Assessment Freeze. Applications and Federal Tax Returns are required. 

This senior freeze program may reduce your property tax bill by freezing the taxable equalized assessed value of your property, which impacts the total tax you pay.  It does NOT freeze your taxes, but it protects you from tax increases due to rising property values. Even if you have applied for and been granted the freeze exemption in prior years, you must renew your application annually. 

To apply for the senior freeze exemption, the applicant must: 

  • Be 65 years or older. 
  • Have a total household income of $65,000 or less for 2022. 
  • Have owned and occupied the home on Jan. 1, 2022 and Jan. 1, 2023.

Homestead Exemption for Persons with Disabilities 

This exemption lowers the equalized assessed value of your home by $2,000. It can be claimed in addition to the General Homestead Exemption and the Senior Homestead Exemption, but cannot be combined with the Veterans with Disabilities Exemption. Annual renewal is required.

To apply for the disabled persons exemption, the applicant must: 

  • Be disabled per the Federal Social Security Act.
  • Have owned and occupied the home on Jan. 1, 2023.

This exemption requires proof of your disability every year.

Veterans with Disabilities Exemption Renewal

The Standard Homestead Exemption for Veterans with Disabilities must be filed every year in order to retain this exemption. However, beginning in 2023, there is a change to the law stating that those veterans with a 100% service-connected disability that is permanent and total will not have to file every year. Those veterans must file in 2023 and then the exemption will be carried forward for subsequent years. All others must continue to file every year.

The renewal can be filed online or in person at the Vernon Township Assessor’s Office. The deadline for filing the renewal application for 2023 is July 31, 2023.

Proof of Disability:

This exemption requires proof of your service-connected disability rating every year, unless you are a surviving spouse of a veteran. The letter must include an issuing date in 2023 and the percentage of overall service-connected disability.
