Attorney General Tim Fox took some strong action Wednesday to fight sales tax expansion efforts harmful to non-sales tax states like Montana. He filed a brief with the Supreme Court of the United States. Fox highlighted Montana’s long history of opposing sales taxes, and warned the impact online sales taxes levied by other states could have on Montana business and consumers.

“Montana businesses shouldn’t bear the burden of serving as deputized tax collectors for states and municipalities with an online sales tax,” Attorney General Fox said. “For many businesses, getting by is already hard enough without the additional challenge of deciphering a complex web of taxing jurisdiction spread across the country. I’m standing up for Montana businesses and pushing back against efforts to force an online sales tax on Montana consumers.”

The issue is a law passed by South Dakota requiring any business engaging in online sales exceeding 200 transactions or $100,000 to collect South Dakota’s online sales tax. Montana businesses going over the threshold established by South Dakota would be required to collect and distribute the sales tax revenue for South Dakota.
