MELISSA BLOCK, HOST:
Technically, consumers are supposed to pay taxes on things they buy online. In fact, few do. Congress is considering a bill called the Marketplace Fairness Act. It would force many online sellers to collect sales taxes for the first time. In the meantime, some states have already enacted so-called Amazon taxes. They force online retailers to collect sales taxes the same way traditional brick-and-mortar stores do.
NPR's Yuki Noguchi reports now on a new study that looks at the impact of those taxes.
YUKI NOGUCHI, BYLINE: Years of slow growth sent many state and local governments hunting for new sources of tax revenue and online retail sales have been a big target. Proponents argue that collecting out of state online retail tax could add $23 billion a year to their coffers. So, Hoonsuk Park and Brian Baugh, two finance PhD candidates at Ohio State University, decided to track five states, including Texas, Virginia and California, that recently had enacted such state laws to see what the effect might be on other retailers. Hoonsuk Park...
HOONSUK PARK: So we find around 10 percent decrease in Amazon purchases after the tax.
NOGUCHI: Park says they collected reams of data from online aggregators of financial information and analyzed what happened as soon as laws enacting new taxes on Amazon took effect. They also noted that 2.7 percent of consumers switched to other retailers - either to other online retailers or to brick-and-mortar operations. This isn't all that surprising. Costs go higher, consumers spend less or look for alternatives.
Brian Baugh co-authored the research. He says some of the Amazon customers didn't go very far. They often purchased instead from Amazon Marketplace, a collection of separate sellers that sell through Amazon but which are small enough that they aren't subject to the new taxes.
BRIAN BAUGH: I predict a lot of this loophole-seeking behavior of households will continue. So they'll continue to seek out retailers that are small and not subject to the tax.
NOGUCHI: Amazon did not respond to the study directly but said it offers lower prices with or without sales tax. The new research only looks at one aspect of the policy debate - that is, what happens to demand. In fact, much more of the focus has been on the burden of cost and compliance with the law. And there, the online retail world is divided.
Those in favor of collecting and remitting taxes say it levels the playing field for local brick-and-mortar stores. In addition to retailers like Wal-Mart that have physical stores, advocates now include Amazon, whose expansion plans make it increasingly likely it will have to pay the sales tax anyway.
Opponents include eBay, which represents a host of mom and pop sellers. The online auction house says the measure would hurt smaller retailers by imposing bigger administrative burdens on them. Bill McClellan is vice president of government affairs for the Electronic Retailing Association, which opposes the Marketplace Fairness Act. He says the bill would decimate small online retailers because they wouldn't be able to absorb the cost of figuring out how to comply with thousands of tax codes around the country.
BILL MCCLELLAN: This study does not change the policy discussion in Washington, D.C. It is a very interesting study in what it examines.
NOGUCHI: The federal bill passed in the Senate but remains stalled in the house. Yuki Noguchi, NPR News, Washington.
