Armstrong Teasdale’s Tax practice area counsels clients ranging from individuals to publicly traded companies in connection with tax planning and strategy, compliance with tax laws, tax reporting and tax controversies.

Our lawyers review and analyze new legislation, regulations, cases and administrative interpretations of tax law on federal, state and local levels to keep abreast of current laws and issues in this rapidly changing and evolving area. By staying current on these complex issues, members of the team provide cutting-edge tax planning that can quickly determine the impact of new rules on our clients, and ensure a client’s tax position on a return or under audit is aggressively supported. Our lawyers, many of whom have backgrounds in accounting, routinely represent clients before the IRS and state tax authorities in connection with audits, appeals and collection matters. Further, we represent clients in tax litigation before state, federal and administrative hearing courts.

Our lawyers work collaboratively and in conjunction with all other practice areas in the firm to ensure our clients’ transactions, settlements, contracts and deals are structured in a tax advantaged manner. We routinely advise Armstrong Teasdale lawyers, clients and other advisers in the areas of mergers and acquisitions, employment matters, estate planning, real estate and corporate structure.
