DuPage County Property Tax Appeals

How do you appeal a property assessment in DuPage County?

DuPage County properties are assessed through township assessment offices, with formal complaints heard by the DuPage County Board of Review. Filing rules and deadlines are tied to the county's publication and notice process, so owners should review the current notice rather than rely on last year's dates.

What are common grounds for a DuPage appeal?

A case may be supported by a recent sale below the implied market value, comparable homes or buildings with lower assessments, incorrect property characteristics, an appraisal, vacancy, or income evidence for a commercial property.

Where do we represent property owners?

We handle appeals across DuPage County, including Elmhurst, Oak Brook, Lombard, Downers Grove, Glen Ellyn, Wheaton, Naperville, Westmont, Clarendon Hills, and nearby communities.

Residential and commercial representation

For homeowners, we focus on accurate property data, comparable sales, and assessment equity. For commercial owners, we evaluate the valuation method, leases, vacancy, operating results, and property-specific market conditions.

How are fees handled?

DuPage County property tax appeals are handled on a contingency basis. There is no legal fee unless Younis Law Group obtains a reduction, subject to the engagement agreement.
