An endorsement of the “Amazon tax” by the left-wing Center on Budget and Policy Priorities has brought the topic back into the news, and while it’s predictable that such a group prioritizes expansion of revenue uber alles, it’s disappointing to see the same principle so thoroughly permeating our government:

[Rep. Steven] Costantino [D-Providence] has said that the law is intended to help level the playing field for local retailers who collect the tax and are at a competitive disadvantage with online retailers who do not.
Gary S. Sasse, director of the state Department of Revenue, said that how state sales tax applies to online purchases has “become an issue that all of the states need to face.”
It could be resolved by Congress, but “unfortunately, Congress has punted” on the issue, he said.
“Short of Congress exercising the necessary leadership on this issue, you’ll have states responding to this issue . . . [by passing] this type of legislation,” Sasse said in an interview at his office on Friday.

Frankly, I find the “competitive disadvantage” argument to be a ruse. Anecdotal evidence suggests that the lack of sales tax essentially adjusts for shipping costs in consumers’ minds or, in the event of free shipping, for the delayed gratification. Given their differing model, some online retailers do have lower prices for particular items, but those differences are independent of taxes and shipping.
The larger point is the distasteful practice of government’s chasing revenue wherever it may exist. A market has developed for untaxed online goods, and reformulating the law in order to siphon some money to state governments that have driven their polities into the ground becomes a matter of Congressional “leadership”?
Congress should leave the law as it is. If other states follow Rhode Island’s lead and attempt to tax all online sales based on the existence of affiliate programs (that offer fees for referrals and the like), I suspect online retailers will continue to end the programs, rather than give up their counterbalance to shipping costs. In the meantime, state-level officials should concentrate on proving their competence at doing something other than grabbing dollars from the private sector.
