Effectively immediately, states will be able to force businesses to charge and pay state and municipality sales taxes for all online shopping. This sweeping policy change came June 21, 2018 from a 5-4 decision at the Supreme Court of the United States when more than forty states had asked the Supreme Court to overrule its past decisions forcing businesses to collect sales tax only when the business had a brick and mortar location or office in the same state as the consumer.
Instead, states will be able to force businesses to collect taxes from sales to consumers regardless of whether the business has a location in these states. Expect states and retailers to react to this ruling and begin collecting sales tax in time for the 2018 holiday season.
