The rise of remote workers during the Covid-19 pandemic has led to a showdown in the U.S. Supreme Court over which state gets to tax their income.
More than a dozen states submitted legal briefs this week to weigh in on a petition that New Hampshire filed with the court in October to stop Massachusetts from taxing residents working remotely. The petition says Massachusetts doesn’t have the right to tax the income of New Hampshire residents who previously commuted to their jobs in Massachusetts but now work from home.
The case hasn’t yet been scheduled for a private conference among Supreme Court justices, who will decide whether they will grant it a hearing. A ruling would have significant budget implications for states that have lost billions of dollars in tax revenue during the pandemic and could set a precedent on taxing remote workers that endures past the coronavirus crisis.
The U.S. Congress has for years discussed setting clearer rules for interstate taxation disputes, but hasn’t passed any legislation. New Hampshire took its complaint directly to the U.S. Supreme Court, which has original jurisdiction over disputes between two or more states.
New Jersey, Connecticut, Iowa and Hawaii submitted a brief Tuesday urging the court to take up New Hampshire’s petition. On Monday, Ohio, Texas and eight other states with Republican attorneys general also weighed in on behalf of New Hampshire.
“The Massachusetts v. New Hampshire issue is no isolated border skirmish between those states. It raises a fundamental national issue that has been festering for decades,” said Edward Zelinsky, who teaches tax law at Yeshiva University’s Cardozo Law School in New York City.
Mr. Zelinsky has filed a friend-of-the-court brief supporting New Hampshire.
Federal courts have held that states may tax the income of nonresidents so long as employees have a substantial link to the taxing state, the taxes are fairly related to services provided by that state, and a tax is apportioned fairly and doesn’t discriminate against interstate commerce.
Massachusetts normally apportions the amount of income it taxes based on the number of days commuters are working in the state, predominantly at firms in and around Boston, it said in a court filing. But the commonwealth issued a rule earlier this year stating it would treat income paid to nonresidents who have stopped traveling to the state because of the pandemic as though they were still commuting.
New Hampshire, which has no income tax, said in its petition that Massachusetts’ rule infringed on its sovereignty, as well as undermined “an incentive for businesses to locate capital and jobs in New Hampshire, a motivation for families to relocate to New Hampshire’s communities, and the State’s ability to pay for public services by reducing economic growth.”
In its own court brief, Massachusetts argued that its rules maintained the status quo to prevent disruption for taxpayers. The commonwealth also said the Supreme Court didn’t have jurisdiction to hear New Hampshire’s challenge because taxpayers who feel they are being unfairly charged could make their case in Massachusetts courts.
Before the pandemic, six states followed what is known as the “convenience rule” for taxing income paid to residents of other states. This is particularly important in major cities that regularly draw commuters across state lines, like Omaha, Neb., and New York City.
Under the rule, work for a New York-based company performed remotely is still taxable in New York if the telecommuting took place for the convenience of the employee, tax lawyers said. That means someone like Mr. Zelinsky, who does research and writing from his home in Connecticut one or two days a week during the academic year, is taxed by New York state on his entire salary because Yeshiva University is located in Manhattan.
Mr. Zelinsky has unsuccessfully challenged this practice in New York courts, and said in an interview that he doesn’t believe the convenience rule is supported by the U.S. Constitution.
New Jersey officials agree. In their brief, they argued that New York was taking more than its fair share by taxing nonresidents who are generating income outside their borders as they work from home.
“They’re not relying on New York public services, they’re not relying on a transit system,” Parimal Garg, chief counsel to New Jersey Gov. Phil Murphy, a Democrat, said of the state’s residents who are no longer commuting to their jobs in New York. “A ruling here could help mitigate the fiscal impact of the pandemic on New Jersey.”
Officials in New York didn’t respond to requests for comment.
The fiscal implications of changing the taxation rules run in the billions of dollars, according to budget officials from several states. In 2018, around 434,000 New Jersey residents paid $3.7 billion in New York income taxes, according to the New York State Department of Taxation and Finance. Almost 87,000 Connecticut residents paid New York an additional $1.3 billion in 2018; those two states’ residents account for about 10% of all the income tax New York collected that year.
Both New Jersey and Connecticut offer their residents a credit on their home-state returns for income taxes paid to other states. The New Jersey Office of Revenue and Economic Analysis estimated this month that around $100 million to $400 million of its annual credits were for work performed at home for New York companies before the onset of the pandemic.
That figure has increased to between $929 million and $1.2 billion because of the public-health crisis, the office said. It estimated that between 44% and 58% of people are now working from home.
Connecticut officials, working with the same telecommuting rates, projected residents would send between $339 million and $444.5 million less in New York income taxes and between $48.2 million and $63.2 million less in income taxes paid to Massachusetts.
