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.

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.
