Our tax attorneys are leaders in providing unparalleled service and innovative solutions to our clients. As some of the pre-eminent tax lawyers in the state, members of our Tax Group are skilled in handling State tax matters at the most complex level. From tax planning to tax controversy and litigation, we cover the tax waterfront.

Our Tax Group has been a go-to national practice for decades. In fact, one of our founding partners, John Paul Jackson, was a nationally regarded authority on tax law whose work helped shape tax legislation in the mid-20th century. Today, our tax attorneys continue that tradition of excellence. Members of the tax group have been recognized in The Best Lawyers in America for Tax Law, hold advanced degrees including the L.L.M in Taxation, are licensed Certified Public Accountants, and have held positions with leading tax organizations throughout the country.

Our clients range from multi-billion dollar corporations to complex family-held entities to private equity and hedge funds. We work in partnership with our clients to achieve their business goals by developing innovative strategies to maximize tax benefits while minimizing potential risks and by providing exceptional representation in tax controversies and litigation. We believe it is impossible to deliver high-caliber tax representation without a deep understanding of all facets of the client’s business. Consequently, we engage attorneys from a variety of practice areas, including corporate, employment, litigation, bankruptcy, and real estate law, to drive client success.

With comprehensive knowledge of Transactional Tax issues, our attorneys guide corporate clients through every stage of development, from initial formation through mergers, acquisitions, spinoffs, transfers, and expansion into new markets. Our attorneys have extensive experience in the complicated and rapidly changing laws surrounding Employee Benefits and Executive Compensation. In addition to this experience, members of our Investment Funds group are skilled in providing tax advice to fund investors.

Some of Texas’ most influential families trust us to provide comprehensive estate and tax planning through our Wealth Planning unit and Family Office Group. Our attorneys serve as primary advisers for many privately held and family-owned businesses, and we represent some of the largest private foundations, associations, and healthcare and educational institutions in Texas.

We have been a leader in Energy Law since the 1800s. Another of our founding partners, A.W. Walker, Jr., developed many of the fundamental concepts of modern oil and gas law. We remain on the cutting edge of tax planning for the energy industry, helping clients maintain a competitive advantage in a rapidly changing field. Our tax attorneys have also successfully contested, litigated, and favorably settled numerous complex tax cases for energy companies, other corporations and individuals.

When it comes to Tax Controversy and Litigation, we combine top-notch tax expertise with one of the most formidable trial groups in the Southwest. Our State & Local tax group includes some of the leading experts on state tax planning and disputes. Our federal tax attorneys are equally skilled in federal tax controversy and have successfully defended corporations and individuals facing IRS audits and tax disputes nationwide. Furthermore, our Litigation practice is among the largest in the Southwest, with trial experience across multiple industry sectors and in nearly all 50 states.
