Missouri Gov. Mike Parson said Tuesday that he wants to enact a law enabling the state to collect millions of dollars of new tax revenue from out-of-state retailers who sell things to Missouri residents.

The new online sales tax provision will be part of Parson's agenda for the legislative session that starts Jan. 9, the governor said in an interview with The Associated Press.

Though there is no definitive plan yet for the potential new revenue, it could help propel other aspects of Parson's agenda to boost infrastructure funding and workforce development.

The U.S. Supreme Court opened the door for states to rake in greater online sales tax collections in a June ruling that upheld a South Dakota law. That decision overturned a decades-old precedent stating that businesses without a physical presence in a state — such as a store, office or warehouse — didn't have to collect sales taxes on behalf of the state. In such cases, customers technically were responsible for paying the tax, but most didn't.

As online commerce has grown, some large retailers such as Amazon already had begun collecting sales taxes for all 45 states that charge them. But others with a physical presence in only a few places haven't been doing so.
