Our Firm


Ivins, Phillips & Barker is exclusively engaged in the practice of federal tax, benefits and compensation, and estate and gift tax law. Our lawyers are nationally recognized to be among the best and brightest, bringing years of government service and corporate experience to bear on our clients' tax problems. We provide seasoned 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.

Founded by two of the original judges on the United States Tax Court in 1935, our decades of focus on the intricacies of the Internal Revenue Code and Department of Labor regulations have led numerous Fortune 500 companies, as well as smaller companies, tax-exempt organizations, and high net worth individuals to rely on us for answers to their most complicated and sophisticated tax planning problems as well as for complex tax litigation. Our experience has taught us that while the tax code is ever-evolving, for most taxpayers it remains dauntingly complex; we keep up on the latest developments in tax reform so that we can provide timely advice on how changes to the law will affect you and your business.

“The firm represents approximately one-third of the Fortune 100 on federal tax (including employee benefits) matters.”
 – Chambers & Partners

We believe our clients are best served by a practice environment in which lawyers concentrate on an area of specialization within the tax law, so that they see all the issues that come to the firm in that area. Unlike other firms that use unnecessarily large teams to solve simple problems, IPB keeps client costs to a minimum with extreme efficiency, outstanding intellect, and practicality. 

We are committed to providing the highest-quality, timely responses to our clients’ needs. We also recognize an obligation to be forward-thinking and to bring potentially beneficial tax planning ideas to your attention, whether you're the Tax Director at a multinational corporation, or an individual taxpayer. 

Our loyal national and international clients know that they can rely on us for the finest, most economical and timely tax advice and tax controversy services available anywhere in the United States.
