This is another post from a tax protest in Barrington which is also in Lake County. Basically states that the appeal must be used until the next quadrenial assessment.
These guys are tricky if you let them get away with it. Only be sure to pay your fair share!
I recently received notice of a 21% increase in my Lake County IL 2008 real estate tax assessed valuation. In 2007, I along with many of my neighbors, were facing a similar increase and protested to the Lake County Board of Review. They agreed with our position and rolled back the 2007 increase. Now, with a year to do their homework and modify their mechanics, the assessor's office found a way to increase the assessment again. This time, we have the ability to protest in another way and that is "MATTER OF LAW". The following is the meat of our protest and I thought some of you might appreciate the sections that are copied below. Wish us luck!
The Lake County Board of Review rules for 2008 set forth a set of "reasonable rules for the guidance of persons doing business with the Board and for the orderly dispatch of business." The rules include an Appeals Based upon Matters of Law, which states:
"Prior Board of Review Decisions. Owner occupied residential property assessment appeals based up on prior year Board of Review decisions should contain the Notice of Finding from the Board of Review from the general assessment year or from the subsequent year where applicable. Aside from substantial cause, prior year decisions on owner-occupied residential properties should be carried forward until the next general assessment year, subject to the Chief County Assessment Officer's equalization. Cases based solely on this reason will be set for review only after a review by the Board or its staff."[i]
Furthermore, Illinois Property Tax Code Article 16 Division 2 Section 16-80 "Reduced assessment of homestead property." states:
"Sec. 16-80. Reduced assessment of homestead property.
In any county with fewer than 3,000,000 inhabitants, if the board of review lowers the assessment of a particular parcel on which a residence occupied by the owner is situated, the reduced assessment, subject to equalization, shall remain in effect for the remainder of the general assessment period as provided in Sections 9-215 through 9-225, unless the taxpayer, county assessor, or other interested party can show substantial cause why the reduced assessment should not remain in effect, or unless the decision of the board is reversed or modified upon review. (Source: P.A. 88-455; 89-126, eff. 7-11-95; 89-671, eff. 8-14-96.)."

I have received many, many separate emails and notes regarding this Tax Protest for Lake County. Unfortunately, at this time I have NO CONTACT with any attorney that can help you with a tax protest. It was written for the homeowner to protest their taxes themselves! It is actually a very simple procedure if you follow my guidelines to be sure your property information is stated correctly with the assessor.
Good luck, it is not as intimidating that they want you to think it is!
