Reed Smith’s State Tax practice has more professionals exclusively focused on state tax issues than any other U.S. law firm. Devoted to the full range of state tax matters, we do more than address individual issues as they arise. Our emphasis is on building strong client relationships, working to create innovative and comprehensive solutions that enable our clients to focus on moving ahead.

We are acknowledged as a leading state tax practice in the United States, with more than 40 dedicated state tax lawyers across seven domestic offices. Our lawyers are from private practice, state government departments of revenue and attorneys general offices, the private sector, in-house, and Big 4 public accounting firms. Some of our lawyers are also CPAs or have accounting degrees and related experience. This deep and varied experience allows us to be more than just litigators; we are tax advisors focused on reducing our clients’ tax expense to increase their bottom line.

Reed Smith’s state tax lawyers serve clients by leveraging the firm’s national network of lawyers with deep tax, technical, industry, and government experience. Our lawyers have diverse backgrounds, allowing us to understand more about our clients and their needs, and not solely the state tax laws impacting them. This depth and breadth of our experience impacts how we address client issues—balancing the law against the economic, business, and social environments in which our clients work every day.

This approach has resulted in our representation of more than 10 percent of the Fortune 500 companies in state tax matters, and recognition by tax and business organizations, including The Wall Street Journal.

We were named one of 2016’s Tax Practice Groups of the Year by Law360. Our state tax lawyers were also commended by both Chambers USA and Legal 500 in their 2018 rankings.
