After this Supreme Court decision, many (perhaps most) states will consider new legislation that requires out-of-state vendors to collect and forward sales tax, even without a physical presence in the buyer’s state. However, Congress might pass a federal law addressing the issue of interstate sales tax collection.
If no federal law is passed, the focus will remain on states’ actions. Assuming that states follow the format of the South Dakota law, companies that do a minimum amount of online retailing may not be greatly affected.
Conversely, small businesses that do a great deal of selling online, or plan to do so, might have to make extensive efforts to collect and forward sales tax to multiple states. Our office can help such companies comply with any requirements that arise.
