Our Approach: Collaborative, Efficient, and Business-Focused to Maximize Results

At Michael Best, we take a proactive approach to tax planning and work to optimize the structure of transactions such as mergers and acquisitions, joint ventures, spin-offs, and related transactions, ultimately achieving maximum tax efficiency. Throughout every tax engagement, we consider not only the client’s immediate tax concerns, but their entire business, as we craft an effective solution.

Our attorneys provide comprehensive tax compliance support and represent clients before all taxing authorities.

When new laws emerge, we implement innovative strategies to minimize negative impacts and capitalize on any opportunities these changes bring.

Michael Best’s approach to tax law is grounded in a deep history. For decades, many of the firm’s most prominent attorneys have been tax lawyers who played leading roles both in representing clients and in formulating tax policy. Our attorneys author numerous leading national and state tax publications, including The Complete Guide to Wisconsin Sales and Use Taxes; teach tax law at institutions such as the University of Wisconsin Law School; and regularly present at tax conferences across the United States.
