“Here we are stymied somehow by a small group of members from both sides of the aisle who won’t even allow us to debate a bipartisan amendment that delays implementation for a year,” Collins said. “We’ve reached a very disappointing and unsatisfactory result if that is where we are.”

The bill would exempt small businesses that earn less than $1 million annually from out-of-state sales and requires states to provide retailers with software to calculate sales taxes based on a buyer’s zip code.

But some senators in states without sales tax, such as Montana, say it would burden retailers in their states by forcing them to collect taxes for other state governments.

“This amendment makes my case. What’s my case? My case is this bill should go to committee,” Baucus said. “There are so many problems that are not thought through. This amendment says delay for a year. [But] why delay? Because there are so many problems … Dealing with the problems in committee is the solution.”

Under current law, states can only collect sales taxes from retailers that have a physical presence in their state. People who order items online from another state are supposed to declare the purchases on their tax forms, but few do.

On Wednesday, the Senate voted 75-22 to proceed to the bill, and last month the body passed a nonbinding budget resolution supporting the Marketplace Fairness language on a 75-24 vote.

Those votes suggest supporters of the bill are likely to see it win approval in the Senate later this week. But some senators from New Hampshire, Montana and Oregon are forcing the Senate to run out the clock on each procedural move, delaying the process.

He said he would allow amendments from those opposing the bill, but that those senators still won't agree to allow the bill to move forward.

“We’re told any amendments that come to the floor today, there will be more objections,” Durbin said before Collins’s amendment was objected to. “I don’t think this makes this institute look very good … We’re supposed to engage in civil debate on the floor and vote.”
