Tax

Overview


Taxpayers worldwide are facing increased scrutiny of, and new attacks against, longstanding tax structures. US corporate taxpayers are subject to some of the highest tax rates in the world, yet are constantly under threat of IRS audits. State and local governments dealing with growing budget shortfalls are developing creative arguments for increasing the tax burden on businesses located inside and outside of their jurisdictions. In this challenging atmosphere, multinational enterprises, mid-market corporations and closely held companies need effective, sophisticated legal guidance.

Initially launched as a tax law firm in 1934, McDermott remains one of the top tax practices in the United States and abroad. Our US federal, international, and state and local tax (SALT) lawyers bring a wealth of institutional experience and subject-specific knowledge to each client matter, enabling us to offer only the most practical and strategic advice on virtually every aspect of tax law.
