Supreme Court Allows Challenge to Colorado Internet Tax Law

A unanimous Supreme Court ruled Tuesday that federal courts can hear a dispute over Colorado's internet tax law. One justice suggested it was time to reconsider the ban on state collection of sales taxes from companies outside their borders. The ruling is a win for business groups that want to challenge the state's so-called "Amazon tax," which requires extensive reporting by out-of-state retailers that don't collect the state's 2.9 percent sales tax from Colorado customers. Online retailers claim Colorado is violating protections for companies doing business in other states.
