Chicago Property Tax Consultants

Every year commercial property values nationwide are at risk of increasing on the tax rolls for taxation purposes. It is important that your properties are analyzed every year to minimize your tax burden. Our seasoned Chicago property tax consultants and attorneys engage in an aggressive but fair approach to value, negotiations, and appeals. In the state of Illinois, our team has ample experience in helping lower property tax values through litigation. Cook County, Dupage County, Will County, Lake County, and the surrounding areas in Chicago require a unique approach with a history of relationships with the Cook County Assessor or local assessors. With some of our appeal cases, a local attorney will need to be brought in, with whom we have terrific relationships. Our Cook County property tax consultants have developed these relationships over the past 40 years.
