A survey of Louisiana voters found that 56 percent are opposed to a change in federal law that would allow state governments to cross state lines and collect sales taxes from online retailers.

The survey of 400 likely voters was conducted June 4-5 on behalf of the National Taxpayers Union, which lobbies for lower taxes, and the R Street Institute, a free-market think tank based in Washington, D.C.

Andrew Moylan, the executive director for R Street, said the results were in line with a Gallup poll taken in June 2013 that indicated widespread disapproval toward a change in Internet sales tax law. Moylan noted that the measure was widely opposed across the board by Louisiana residents of all stripes, from conservative and liberal voters to frequent and infrequent online shoppers.

“It’s not just a knee-jerk opposition to taxes that concerns people the most, it’s the expansion of state power,” he said during a conference call with reporters Wednesday.

In May 2013, the Senate passed the Marketplace Fairness Act, which would allow a state to require sales tax collection by out-of-state retailers if the sales tax system was simplified.

The bill came about after complaints from brick-and-mortar stores about the growing size of the Internet retail business.

Moylan said there are concerns the House could take up the issue during a lame-duck session at the end of the year, attaching it to an existing bill that extends the guarantee that people will not have to pay taxes to get onto the Internet. “The basic takeaway is we have a bipartisan majority who don’t like the scheme,” he said.
