Tim focuses his practice in the state and local tax area. His work primarily involves New York State and New York City tax litigation and controversy.

He is often quoted by media outlets, including The Wall Street Journal, The New York Times, Bloomberg, and Forbes, on residency and other state tax issues. Under his direction, the Tax Residency Practice authored What to Expect in a Residency Audit, a detailed guide to residency rules and audits in New York and other states.

Audits and Litigation

Tim has handled thousands of state tax audits, litigated cases, and appeals. His track record in reported cases within New York’s Division of Tax Appeals is exceptional, and his experience extends into the state courts as well, highlighted by a win in a watershed 2014 residency case in New York’s highest court. In that case, Hodgson Russ attorneys represented the victorious taxpayer in a highly anticipated decision in a tax residency case before the New York Court of Appeals in February 2014. In John Gaied v. New York State Tax Appeals Tribunal, the court agreed with the position advocated by Hodgson Russ on behalf of Mr. Gaied and established a new rule for determining when individuals domiciled outside of New York may still be taxed in New York as "statutory residents." This was the first case in several decades to prompt New York's highest court to examine the scope and extent of New York's residency rules. The case has been widely cited in the press, including the Wall Street Journal and Law360. Other reported cases in the income tax and sales tax areas include:

Residency and Tax Planning

Over the past two decades, Tim and his colleagues in the residency practice have assisted thousands of clients in effectuating changes of residency from New York and other states and helping with state tax planning on major income events. They have also assisted hundreds of clients with planning associated with New York State's 548-day rule. This planning involves detailed work with the client and advisors on interpretation and application of New York's residency provisions.  And very often these residency-planning matters lead to residency tax audits.  Tim and the residency team at Hodgson Russ handle more of these audits than any other law firm in the country, and their track record of success is exceptional, in particular in those cases where they’ve worked with the clients on the planning process.

Joe is joined by Tim Noonan and Diana Mathis for an in-depth discussion of the rules governing changes of residency out of New York to a foreign country.

  • Obus and the Future of Statutory Residency

    A major win for taxpayers, the decision in Matter of Obus v. New York State Tax Appeals Tribunal is final! Joe is joined by guests Tim Noonan, Andrew Wright, and Emma Savino to discuss this landmark tax case, which will dramatically shift the rules for New York’s statutory residency test. We break down the cases that led up to this point, what actually happened in Obus, why the impact of the case is significant, and what the future may hold for legal interpretation of what constitutes a permanent place of abode in New York. A once purely mechanical test, the statutory residency test now looks to have a major subjective component as part of the analysis, as a result of the Obus decision. Joe and his guests also give their thoughts on whether the State will take action in response to this major change.
