By a 5-1 vote, the New Jersey Supreme Court has curbed the authority of the state Division of Taxation to collect taxes on Johnson & Johnson’s fully owned insurance subsidiary.

The justices upheld a $56 million refund awarded by the Appellate Division to Johnson & Johnson for what the company says is overpayment of taxes on self-procured insurance. The court’s majority ruled that a 2011 legislative amendment to the state’s insurance premium tax statute requires Johnson & Johnson to pay taxes based only on risks in New Jersey, rather than its entire U.S. premium.
