An anonymous reader writes with this quote from an Associated Press report:
"Amazon.com will begin collecting Indiana's 7 percent sales tax from customers in the state in 2014, under an agreement announced Monday. ... Gov. Mitch Daniels' office said Indiana will become the fourth state with such a tax collection agreement with Seattle-based Amazon. It follows a lawsuit by Indianapolis-based shopping mall owner Simon Property Group against the state over the issue and a lobbying push on state legislators by traditional retailers to end what they call an unfair price advantage for online retailers. The deal doesn’t include any other companies, but Daniels said the state is asking Congress to require all online businesses to collect state sales taxes."
