Groups like the National Retail Federation and the Retail Industry Leaders Association, strong backers of the online sales tax measure, have been urging supportive senators to offer the bill as an amendment to the Senate budget.
Under current law, states are only obligated to collect sales taxes from retailers that currently reside within their borders.
Retail groups say this gives Internet sellers an unfair advantage over brick-and-mortar shops. The legislation introduced this year, which melds previous House and Senate proposals, would allow states to collect from Internet sellers that don’t reside in their state.
The large online retailer Amazon, currently spreading into an increasing number of states, also backs the legislation.
But conservatives like Grover Norquist have said they don’t like the proposal, and eBay and other online retailers that oppose the measure say they are making the case that the bill favors large companies over smaller start-ups.
Backers of an online sales tax measure pushed to get a bill passed during last year’s lame-duck session, but fell short. And while supporters are confident they have the support to get a bill enacted, key committee chairmen have said they’re skeptical of the measure.
