Get ready to pay sales tax more often when you shop online

Supreme Court rules states can collect sales tax but says Congress should act

States stand to pocket billions as Supreme Court rules internet businesses must collect sales taxes for all online purchases.

WASHINGTON — States will be able to force more people to pay sales tax when they make online purchases under a Supreme Court decision Thursday that will leave shoppers with lighter wallets but is a big financial win for states.

Consumers can expect to see sales tax charged on more online purchases — likely over the next year and potentially before the Christmas shopping season — as states and retailers react to the court’s decision, said one attorney involved in the case.

The high court’s 5-4 decision overruled a pair of decades-old decisions that states said cost them billions of dollars in lost revenue annually. The decisions made it more difficult for states to collect sales tax on certain online purchases, and more than 40 states had asked the court for action. Five states don’t charge sales tax.

The cases the court overturned said that if a business was shipping a customer’s purchase to a state where the business didn’t have a physical presence such as a warehouse or office, the business didn’t have to collect sales tax for the state. Customers were generally responsible for paying the sales tax to the state themselves if they weren’t charged it, but most didn’t realize they owed it and few paid.

Justice Anthony Kennedy wrote that the previous decisions were flawed.

“Each year the physical presence rule becomes further removed from economic reality and results in significant revenue losses to the States,” he wrote in an opinion joined by Justices Samuel Alito, Ruth Bader Ginsburg, Neil Gorsuch and Clarence Thomas.

Kennedy wrote that the rule “limited States’ ability to seek long-term prosperity and has prevented market participants from competing on an even playing field.”

The ruling is a victory for big chains with a presence in many states, since they usually collect sales tax on online purchases already. Now, rivals will be charging sales tax where they hadn’t before.

Big chains have been collecting sales tax nationwide because they

typically have stores in whatever state a purchase is being shipped to. Amazon.com, with its network of warehouses, also collects sales tax in every state that charges it, though third-party sellers who use the site don’t have to.

Until now, many sellers that have a physical presence in only a single state or a few states have been able to avoid charging sales taxes when they ship to addresses outside those states. Online sellers that haven’t been charging sales tax on goods shipped to every state range from jewelry website Blue Nile to pet products site Chewy.com to clothing retailer L.L. Bean.

Sellers that use eBay and Etsy also haven’t been collecting sales tax nationwide.

Under the ruling Thursday, states can pass laws requiring out-of-state sellers to collect the state’s sales tax from customers and send it to the state.

The losers, said retail analyst Neil Saunders, are online-only retailers, especially smaller ones. Those retailers may face headaches complying with various state sales tax laws, though there are software options to help.

Chief Justice John Roberts and three of his colleagues would have kept the court’s previous decisions in place.

“E-commerce has grown into a significant and vibrant part of our national economy against the backdrop of established rules, including the physical-presence rule. Any alteration to those rules with the potential to disrupt the development of such a critical segment of the economy should be undertaken by Congress,” Roberts wrote in a dissent joined by Justices Stephen Breyer, Elena Kagan and Sonia Sotomayor.
