The Senate passed a non-binding version of this bill in March, as part of the budget agreement. Passage of the amendment by a 75-24 vote makes it likely that the Senate will be able to pass some version of the Marketplace Fairness Act at some point in the near future.

That vote split Republicans, but five Democrats voted against it, including Senate Finance Committee Chairman Max BaucusMax Sieben BaucusBernie Sanders flexes power on single-payer ObamaCare architect supports single-payer system Trump has yet to travel west as president MORE (D-Mont.). Baucus has said he does not want to subject companies in Montana — which has no sales tax — to the bookkeeping challenges of a new online sales tax.

Baucus has said the issue should first be discussed in his committee, but for now, Senate Democratic leaders seem content to bring it right to the floor. As a start, the Senate will vote Monday at 5:30 p.m. on a motion to end debate on a motion to proceed to the bill.

The House is not in Monday, and returns Tuesday to work on a handful of suspension bills.
