Congress has the ability to nationalize sales tax collection and remittance across State borders and bills have been introduced in the past that propose to do just that.
So with this decision we might (should) see Congress solving this issue. The Supreme Court had practically begged Congress to act before overturning Quill.
>In its 1992 ruling in Quill v. North Dakota, the High Court said states could require retailers to collect sales tax only if those businesses had a substantial physical presence — known in legalese as nexus — in their jurisdictions. But the Court, which called the legal issues surrounding nexus a “quagmire,” strongly urged Congress to resolve the many unanswered questions surrounding remote sales: “The underlying issue is not only one that Congress may be better qualified to resolve, but also one that Congress has the ultimate power to resolve.”
Which is, in fact, the point of the Roberts' led dissent as well. Basically that this would be better off as a Congressional effort and that, by overturning Quill--even though there were good reasons to do so--the majority has thrown a wrench into ongoing efforts to work towards a national solution.
