The U.S. Senate took a cue from retailers and states by passing a bill that would subject online shopping to state sales tax, with 69 to 27 in favor. States currently can only require online retailers to collect tax if the store has a brick-and-mortar setup in the state. President Obama has voiced support for this measure, but it is expected to be a tougher sell in the House, where conservatives view it as a tax increase.
