The Supreme Court, today, denied New Hampshire’s motion for leave to file a bill of complaint challenging Massachusetts’ COVID-related tax regulations.  The decision comes little more than a month after the Acting Solicitor General of the United States filed an amicus brief urging the court to deny the motion.  In addition to New Hampshire, the decision will leave New Jersey and other states (nearly fourteen states had filed amicus briefs urging the Court to take the case) disappointed.  The case was seen as an indirect threat to New York’s convenience of the employer rule, which operates similarly to the temporary regulations adopted by Massachusetts.  See earlier coverage here and here.

On Monday, October 19, the State of New Hampshire filed a bill of complaint in the Supreme Court of the United States asserting that its southern neighbor, Massachusetts, is violating its state sovereignty.  The suit attacks Massachusetts’s emergency regulations governing the taxation of income during the COVID-19 state of emergency. Massachusetts enacted a rule pursuant to which income earned by a nonresident of Massachusetts who worked in Massachusetts prior to the pandemic but who is working from home outside of the state remains Massachusetts-source income subject to Massachusetts income tax.  Accordingly, employers would be required to continue to withhold Massachusetts income tax on wages paid to those individuals even though the individuals are no longer working in Massachusetts.  Although the Massachusetts guidance is among the most sophisticated and detailed withholding guidance issued by the states during the pandemic, it is not alone in taking this approach.  Rhode Island issued regulations substantially similar to Massachusetts, and the Pennsylvania Department of Revenue has issued similar guidance in the form of FAQs posted on its website.  Other states have hinted at taking a similar approach, but the guidance is often vague and left open to interpretation.
