Summary
William “Will” Vietti focuses on tax issues related to public finance transactions, helping to solve tax issues throughout the life cycle of tax-advantaged obligations.
Working with issuers, bond counsel and disclosure counsel, Will ensures that clients’ bonds receive the expected treatment under U.S. federal income tax law. He regularly drafts tax-exemption certificates for new money and refunding transactions, analyzes private-use and rebate issues that may arise when bonds are outstanding, and helps structure refunding when existing debt is retired, or refinancing becomes necessary.
Representing municipalities, metropolitan districts, 501(c)(3) nonprofit organizations, and other entities issuing tax-exempt debt, he helps ensure that the debt being issued meets the requirements of the U.S. Internal Revenue Code and accompanying regulations. Additionally, he helps organizations secure lower-cost financing for capital improvements through tax-exempt debt, making sure that all of the technical requirements are satisfied in order to issue specific types of tax-advantaged debt instruments.
With patience, skill, and a deep knowledge of the tax rules, Will carefully considers each transaction and the individual circumstances from an economic standpoint. Then he applies the tax rules to the specific facts to best position the client. Before joining the firm, Will served as a law clerk for Judge Elizabeth Crewson Paris in the United States Tax Court and worked in the Financial Instruments Group at Deloitte Washington National Tax.
