The U.S. Supreme Court will consider freeing state and local governments to collect billions of dollars in sales taxes from online retailers, agreeing to revisit a 26-year-old ruling that has made much of the internet a tax-free zone. Heeding calls from traditional retailers and dozens of states, the justices said they'll hear South Dakota's contention that the 1992 ruling is obsolete in the e-commerce era and should be overturned. State and local governments could have collected up to $13 billion more in 2017 if they'd been allowed to require sales tax payments from online merchants and other remote sellers, according to a report from the Government Accountability Office, Congress's non-partisan audit and research agency. Other estimates are even higher. All but five states impose sales taxes.

The high court's 1992 Quill v. North Dakota ruling, which involved a mail-order company, said retailers can be forced to collect taxes only in states where the company has a "physical presence." The court invoked the so-called dormant commerce clause, a judge-created legal doctrine that bars states from interfering with interstate commerce unless authorized by Congress. South Dakota passed its law in 2016 with an eye toward overturning the Quill decision. It requires retailers with more than $100,000 in annual sales in the state to pay a 4.5 percent tax on purchases. Soon after enacting the law, the state filed suit and asked the courts to declare the measure constitutional.
