Jackie J. Cook

Jackie leads the firm's Tax Division, representing publicly traded and privately held companies, small businesses, families, and individuals. She also consults with labor unions and employee benefit funds regarding state and local tax issues, such as analyzing unique property tax considerations for training fund properties.

For the first decade of Jackie's career she was a litigator with a large international law firm based in Detroit and a large national firm based in Chicago. She has experience as an in-house tax attorney for a Fortune 500 company where she gained a client’s perspective managing litigation and advising internal corporate clients regarding corporate acquisitions, construction contracts, city income tax, state taxes, and property taxes.

Today -- whether she is representing a large automotive manufacturer or supplier, a service company, a retail business, or a nonprofit organization -- she makes it her priority to understand the client’s business purposes and operations before crafting the best solution for resolving their state or local tax issue.

Jackie navigates clients through each stage of a state or local tax issue, from planning to audit through litigation and appeals. Her diverse background includes property tax appeals, Michigan and city income tax disputes, and sales and use tax controversies. She also has worked on matters involving election law, municipal law, general commercial litigation, including contract and vendor disputes, real estate acquisitions and landlord-tenant disputes, administrative law and state and local licensing, and governmental investigations.

Jackie continues to be a leader and frequently speaks in the Michigan tax arena, having served as former chair and 10-year council member for the State Bar of Michigan’s Taxation Section.
