O'Keefe Lyons & Hynes is a leading commercial property tax law firm, providing tax assessment appeals, complex property tax litigation, and related services for commercial real estate owners, developers, investors and management firms. The firm oversees a proprietary tax database that allows for constant evaluation, property tax analysis and future tax modeling to support clients' tax planning strategies. The firm's attorneys have been in the forefront of understanding, shaping, defending -- and in some cases, writing -- the law. The seasoned commercial real estate tax attorneys have the requisite experience, resources and strategic insights to address complex property tax matters. One senior member of our firm leads a nationally-recognized property tax litigation team and, in 2020, was lead counsel in persuading the U.S. Court of Appeals for the Seventh Circuit to uphold federal jurisdiction in a case challenging restrictive interpretations of the Illinois Property Tax Code on constitutional grounds. Our lawyers have worked in the public sector -- from the Cook County Assessor’s Office to the Board of Review for Cook County -- and understand the complexities of property tax appeals and litigation, property tax planning and related matters. The O’Keefe firm brings an unparalleled level of experience and a passion for helping clients maneuver through challenging property tax matters. The firm’s clients are prolific commercial real estate developers and prominent property management firms, global industrial concerns, marquee hotels, national retailers, shopping center developers, Fortune 500 corporations, along with area hospitals, small businesses and not-for-profit and religious organizations.
