Have you heard about South Dakota’s latest move regarding the online sales tax debate?

Last month we discussed how two states, Louisiana and Alabama, are taking matters into their own hands regarding the online sales tax debate. Now another state, South Dakota, is forcing the issue.

South Dakota’s Case Regarding Online Sales Tax

If you recall from our previous posts about the online sales tax debate, states are frustrated that they can’t collect the revenue from purchases made via the internet, and retailers claim it’s too difficult to keep track of the wide variety of tax codes for every single state, county and municipality – especially for small internet retailers.

Instead of waiting for Congress to come to some sort of agreement, South Dakota has taken matters into their own hands by passing Senate Bill 106, allowing the state to collect taxes from sales made from online retailers – even if they don’t have nexus within South Dakota itself. This challenges the 1992 ruling in Quill Corp. v. North Dakota, in which the U.S. Supreme Court ruled that only businesses with an actual physical presence in the state (or nexus) needed to collect sales tax from residents.

Passing the law isn’t all South Dakota did. Now it’s suing four internet retailers (Wayfair, Systemax, and Newegg) to try to force a judicial decision in their favor.

But that’s not all; NetChoice and the American Catalog Mailers Association sued South Dakota as well, claiming the new law violates the Quill decision.

What Do We Think?

While we do disagree with the laws states like South Dakota, Louisiana and Alabama are writing in order to circumvent the Quill decision, we are open to seeing how this case plays out in the U.S. Supreme Court (if it makes it there).

    What bothers me most about these state actions is that businesses must sue in the state courts instead of the federal courts (interstate commerce?) and that states cannot be sued for legal fees on what is clearly a violation fo litigated issues. Perhaps, if businesses could sue in federal courts and collect legal fees from the states doing this nonsense, the states just might hesitate with this nonsense.
