McHenry County Property Tax Assessments

Alejandro Benitez heads the McHenry County Assessment Office. It is at 667 Ware Rd, Room 106, Woodstock. Call (815) 334-4290 for questions. The McHenry County assessments page explains how property values are set and what you can do if you disagree with your assessed value.

Under 35 ILCS 200, all property in McHenry County is assessed at 33.33% of fair market value. A home with a market value of $240,000 would have an assessed value of about $80,000. The equalized assessed value, or EAV, is what the tax rate gets applied to. Township assessors do the initial work in McHenry County, and the Supervisor of Assessments reviews their numbers for accuracy and consistency. The state also applies an equalization factor to make sure values are uniform across the county and the state.

If your value seems too high, you start by filing a complaint with the McHenry County Board of Review. They look at your evidence and can adjust the assessment. After that, you can take it to the Illinois Property Tax Appeal Board. All appeal results become part of your McHenry County property tax records and stay on file with the assessment office. The outcome of an appeal can change your tax bill for the year in question and sometimes for future years too.
