(NET News) -- NETnebraska.org reports on an effort by Nebraska retailers to require out-of-state companies to collect sales taxes for online purchases. The story points out that a 1992 U.S. Supreme Court decision gave Congress "the ultimate power to resolve the issue. But over the next quarter-century, as online sales increased, Congress has done nothing to change the situation." The head of the Nebraska Retailers, Jim Otto, "said Nebraskans who buy things online are supposed to pay the tax, but online retailers don't collect it." Last year, U.S. Supreme Court Justice Anthony Kennedy said the court should reexamine its 1992 decision, the story notes, and now, "states have begun to act on their own, to set up a test case." The story references a new law in South Dakota that says "companies with more than $100,000 in sales or 200 transactions in the state have to collect sales tax." Other states are considering similar plans.
