State sales taxes cut Amazon's purchases by 9.5 percent: Study

E-commerce giant Amazon has a distinct advantage on the sales tax front—in most places.

In states that do collect taxes on Amazon's sales, customers spend 9.5 percent less on Amazon purchases according to a study by the National Bureau of Economic research. Details of the study were reported in Vox.

The 245,000 households surveyed in the study also apparently flocked to other retailers. Competing online retailers saw their business grow 20 percent in those states, and brick-and-mortar retailers saw their business grow 2 percent, according to the study.

The study comes as Congress considers the Marketplace Fairness Act, a bill that would allow states to collect taxes on all e-commerce purchases.
