Legislative Tax Practice

  • The Holland & Knight Legislative Tax Team helps clients shape federal tax legislation and rulemaking by working with the leadership of Congress, the Biden Administration, the U.S. Department of the Treasury and the Internal Revenue Service (IRS).
  • Members of our team have strong tax policy experience and relationships with Washington decision-makers. The team includes former members of Congress, including a member of the House Ways and Means Committee, former U.S. Department of the Treasury and IRS officials, and a bipartisan group of former high-level staff from congressional tax-writing committees.
  • Our team also has significant experience in leading tax-related congressional investigations in the U.S. House and Senate, as well as defending numerous clients across industries in investigations by the House Ways and Means Committee and Senate Finance Committee.
  • All industries are affected by tax policy, and we represent a diverse range of clients whose interests are at stake in tax legislation in general and in the coming major tax overhaul likely to occur in 2025.


The Tax Cuts and Jobs Act included the widest-ranging changes to the Internal Revenue Code since 1986. Many of the changes it included expire at the end of 2025, unless Congress acts. Holland & Knight was active during the Act's development and passage, garnishing significant wins for many of our clients. Our attorneys and policy advisors are intently focused on forthcoming 2025 legislative tax changes and how they might affect our clients, as well as identifying opportunities that the changes bring. We are also constantly monitoring and involved in regulatory tax changes, with advocacy before the Treasury Department and IRS.

Holland & Knight has a deep bench of advocates who have held policymaking positions under both Republican and Democratic leaders in Washington. This gives us bipartisan insight into the legislative and rulemaking processes – no matter which party wins an election. Holland & Knight also has deep knowledge and experience in the regulatory process given our collective experience working within the government at the Treasury Department and IRS.

Our team also represents clients before the Organization for Economic Cooperation and Development (OECD) and advocates for changes to Pillar One, Pillar Two, the Common Reporting Standard and other OECD projects.

In addition, our team is well situated to handle tax-related congressional investigations. We work closely with Holland & Knight's Congressional Investigations Team, which consists of professionals who have led congressional investigations as committee chairpersons, served as investigative staff on both the House Ways and Means and the Senate Finance committees, served with the U.S. Department of Justice's Tax Division and have a record of success as white collar litigators.
