With more than 100 tax lawyers worldwide, our Tax practice covers every aspect of corporate, partnership and individual taxation in the United States, Europe and Asia, including taxation of cross-border transactions and state and local issues. The team includes sub-practices in transactions, consulting and planning, audits, administrative appeals and litigation, and government relations. Our insurance tax practice represents insurers as well as reinsurers. Our work includes assisting with the organization and operation of offshore companies as non-CFCs and non-PFICs, drafting operating guidelines for non-US companies to follow so as not to be subject to US net income taxation, and addressing insurance industry-specific questions.

In addition, we regularly represent many of the world’s largest banks in connection with complex financing transactions, as well as planning, securitization, financial products and investment fund practices.
