About John
John Sweeney has spent decades working at the intersection of accounting and law. He earned a B.S. in Accounting from Arizona State University (B.S., 1979), a J.D. from Elisabeth Haub School of Law at Pace University (J.D., 1982) and an LL.M. in Tax Law from New York University School of Law (LL.M., 1983). Those academic steps gave him technical grounding and a legal framework for advising clients on tax and regulatory matters.
After completing his LL.M., Sweeney moved into private practice. He is admitted to practice in the District of Columbia, New York and Connecticut. Over time he combined his accounting background and legal training to address issues that sit at the crossroad of finance and law. That combination shapes the way he approaches client matters and case evaluation.
Sweeney works as a lawyer at Sweeney Legal, LLC. In that role he handles matters that commonly arise in tax practice, including tax planning, compliance and dispute resolution. He represents individuals and businesses in conversations with tax authorities and in negotiated settlements. His experience in accounting helps him review financial information and communicate complex tax positions in plain language.
He maintains memberships in the Connecticut Bar Association, the New York Bar Association and the Washington DC Bar Association. Those affiliations keep him connected to evolving practice rules and continuing legal education. He also draws on professional networks in the three jurisdictions where he is licensed when a matter crosses state lines or raises multi-jurisdictional questions.
Colleagues describe Sweeney as deliberate and practical in how he handles cases. He tends to prioritize options that reduce exposure and resolve issues efficiently when that is possible. At the same time he prepares for contested matters when a negotiated outcome is not achievable. His work reflects his dual training in accounting and law and a long career focused on tax-related legal issues.
He practices at Sweeney Legal, LLC, concentrating on tax matters and related legal issues.
