Rebecca A. O'Neill

Senior Associate

A shared commitment to providing exceptional client service drew Rebecca O’Neill to Stein Sperling’s Tax Practice group. Rebecca has long been fascinated by tax and transactional law and appreciates the opportunities to advocate for individual clients, businesses and tax-exempt organizations in these realms.

As part of Stein Sperling’s nationally recognized tax litigation and controversy team, Rebecca recognizes that while many of her clients may have a sense of the goals they wish to achieve, they need guidance in choosing the optimal tax strategies for doing so. She believes that looking at the big picture and analyzing the full breadth of the case is crucial to securing a positive outcome. Sincere and communicative, Rebecca strives to understand her clients’ needs so that she can provide tailored advice while also anticipating issues clients may not have considered.

Rebecca focuses her practice primarily on business transactions, including advising on such matters as entity formation, reorganizations, business succession and asset or equity sales. Additionally, Rebecca advises tax-exempt organizations, such as public charities, private foundations and others, helping them navigate and plan for issues they face at all stages, including formation, obtaining tax-exempt status, soliciting charitable contributions and a broad range of tax compliance and corporate governance issues.

Prior to joining Stein Sperling, Rebecca practiced estate planning and transactional and tax law with firms in New Jersey and Pennsylvania.
