About

Provided by McDermott Will & Emery LLP

McDermott is a law firm of choice for clients seeking the highest quality domestics and international tax advice. Chicago practice combines two main groups: federal tax and state & local tax. In both areas, we handle a mix of both transactional and contentious work.

We are often called in to act as special tax counsel alongside large New York firms handling the corporate aspect of M&A transactions

International tax is a large part of our practice, typically advising on US tax aspects of cross-border deals, and high-profile advisory work. We advise multinationals and companies in 70+ countries.

We have the largest state & local tax department in the US with a dedicated team that works on advisory and litigation matters for the world’s biggest companies.

Out Chicago practice is a standalone tax department – 80% of our work is self-generated, so it comes directly to the tax team, not via the corporate or litigation departments – a reverse of the normal position in large law firms.

We maintain the premier trusts and estates practice in Illinois. A sizeable team of partners in Chicago advise wealthy individuals, family offices, and trust companies.

McDermott is one of few large firms with a high-end in-house transfer pricing team. In particular, we are one of few firms with expertise in state transfer pricing.

McDermott started life as a tax firm and tax remains central to the Firm’s identity; as a “pure” tax practice, clients are come to us because of this commitment to tax law.
