In a 5-4 decision, the Supreme Court ruled today that states may now require online retailers to collect sales taxes from consumers, regardless of where the business is located or the product is delivered. In 1992, the same court ruled that a business had to have some kind of "physical presence" or "nexus" in order to be required to collect sales tax in a state. With the increased use of online shopping, however, it turns out not all taxpayers report non-taxed purchases to the states in which they reside. In fact, an estimated $33.9 billion goes uncollected in sales taxes each year, costing states a significant sum. Additionally, internet shopping tax-free has hurt the brick-and-mortar stores that already have higher operational costs due to a physical presence in a state, since they must collect sales tax on taxable transactions.
Recently, Forbes magazine named South Dakota as one of the top 10 states for business, particularly since it ranked number one in the cost of doing business. A new state law will likely keep South Dakota in first place for in-state business statistics, to the detriment of out-of-state sellers. Last month, South Dakota Governor Dennis Daugaard signed into law a bill that requires many out-of-state sellers to register with the state and begin collecting sales tax. All sellers conducting more than 200 transactions with South Dakota purchasers, or making more than $100,000 in gross sales to South Dakota, must register with the state.
