Armando Gomez concentrates his practice on a broad range of tax controversy matters, as well as transactional and planning situations.


Mr. Gomez represents clients in federal and state tax controversy matters, including in connection with examinations, administrative appeals and special programs designed to reach expedited results, and in litigation before the United States Tax Court and other federal courts. In recent years, he has represented clients in litigation involving partnership issues, tax credit disputes, estate and gift tax matters, and Administrative Procedure Act challenges. He also has counseled clients in summons enforcement matters and in criminal tax investigations, and has acted as special tax counsel in connection with internal investigations on tax-related matters.

He also represents clients in connection with congressional investigations, including in the largest-ever congressional investigation of a single corporate taxpayer.

In recent years, Mr. Gomez’s transactional practice has focused on representing developers and investors in connection with various renewable energy projects. He also advises clients on structuring and financing other partnerships and joint ventures.
