New York's Remote Worker Tax Rule Faces Renewed Constitutional Challenge in Court

ALBANY, N.Y. — A long-standing constitutional challenge to New York’s controversial method of taxing out-of-state remote workers is set for a new hearing, with oral arguments scheduled for June 1 in a state court. The case, brought by Connecticut resident and Cardozo School of Law professor Edward A. Zelinsky, once again puts the state’s “convenience of the employer” rule under judicial scrutiny, a policy that has become increasingly contentious in the era of widespread remote work. At the heart of the lawsuit is New York’s unique tax doctrine, which requires employers to treat wages earned by an out-of-state employee as New York-source income if the employee is working from home for their own convenience rather than for the necessity of their employer. Consequently, these remote workers are subject to New York income tax on 100% of their earnings, just as if they were physically commuting to their New York office every day. Zelinsky, who teaches at the New York City-based law school but performs much of his work from his home in New Haven, Connecticut, argues that this rule is unconstitutional. His lawsuit contends that by taxing income earned entirely outside its borders, New York violates the U.S. Constitution’s Commerce and Due Process clauses. The Due Process Clause limits a state's power to tax activities that lack a sufficient connection, or “nexus,” to the state, while the Commerce Clause prevents states from enacting laws that unduly burden interstate commerce. This is not Zelinsky’s first attempt to dismantle the rule. He previously challenged the policy over work he performed in 2019, but state courts ultimately sided with the New York Department of Taxation and Finance. This new case focuses on the 2020 tax year, a period when the global pandemic forced a massive and abrupt shift to remote work, making the issue more pressing for a far larger pool of taxpayers. For decades, the convenience rule primarily affected a limited number of employees living in neighboring states like New Jersey, Connecticut, and Pennsylvania while working for New York-based companies. However, the post-2020 normalization of hybrid and fully remote work arrangements has significantly expanded its impact, creating complex compliance challenges for small and mid-sized businesses and frustrating employees who now face taxation from two states on the same income. While an employee’s home state typically provides a tax credit for taxes paid to another state, the calculation can be imperfect, sometimes resulting in a higher overall tax burden. More immediately, the rule creates significant administrative burdens for employers, who must navigate a patchwork of conflicting state laws to manage payroll withholding correctly for a distributed workforce. The legal landscape for challenging these rules is difficult. In 2021, the U.S. Supreme Court declined to hear a similar case, New Hampshire v. Massachusetts, in which New Hampshire sued Massachusetts over its temporary rule taxing New Hampshire residents who were working remotely for Massachusetts companies during the pandemic. The court's refusal to take up the case was seen as a setback for opponents of cross-border remote work taxation, leaving challenges to be fought in state courts. Tax attorneys familiar with the Zelinsky case, according to Bloomberg Tax, believe that for any meaningful change to occur, the issue must ultimately be decided by the U.S. Supreme Court. The path through the New York state court system is viewed as the necessary first step toward a potential petition to the nation's highest court. A victory for Zelinsky could have profound implications, not only for New York, which collects substantial revenue from out-of-state remote workers, but also for the handful of other states with similar convenience rules, including Delaware, Nebraska, and Pennsylvania. We frequently see small and mid-sized businesses struggle with this web of state tax laws. The 'convenience' rule is particularly burdensome, creating significant compliance headaches and financial uncertainty for employers trying to support a flexible workforce. While Professor Zelinsky's case is important, a final resolution from the Supreme Court could be years away, if it comes at all. In the meantime, companies with remote employees tied to New York offices must meticulously track work locations and withhold taxes according to New York's stringent rules. Getting this wrong can lead to costly penalties and audits. This is precisely the kind of complex multi-state issue where professional guidance becomes essential.
