Firm Details

Ivins, Phillips & Barker, founded by two of the original judges on the United States Tax Court in 1935, is the leading law firm in the United States exclusively engaged in the practice of federal income tax, employee benefits and estate and gift tax law.  The firm’s lawyers are nationally recognized to be among the best and brightest in the country.  Our decades of focus on the intricacies of the Internal Revenue Code have led numerous Fortune 500 companies, as well as smaller companies, tax exempt organizations, and high net worth individuals to rely on the firm for answers to the most complicated and sophisticated tax planning problems as well as for complex tax litigation.

We provide expert counsel in all major areas of tax law, and we offer prompt and efficient attention, whether with respect to the most detailed and intricate of issues or for rapid responses to emergency situations.  The firm does not pretend to offer low billing rates. What we do offer is the combination of extreme efficiency with outstanding intellect and practicality.  Totally absent is the costly overstaffing and layer upon layer of review that turns seemingly lower hourly rates into significantly larger final bills.

Our clients are not subjected to sales pitches and untoward tax shelter offerings.  We view our exclusive responsibility as providing the highest quality, timely responses to clients’ needs. We also recognize an obligation to be proactive and bring potentially beneficial tax planning ideas to the attention of clients.  This type of service is provided to all clients without the expectation of commissions or percentage fees.  When clients determine to pursue such advice further, we charge fees on an hourly basis for any additional services requested unless the client initiates a request for some alternative billing arrangement.

Ivins, Phillips & Barker assures its loyal national and international clients that they can rely on the firm for the finest, most economical and timely tax advice and litigation services available anywhere in the United States.
