Originally posted by vonBaloney There is actually a bunch of new tax. Many states becoming looser about the definition of whether a sale requires it or not.
Not really. States used to be prohibited from forcing out of state vendors from collecting and remitting sales tax due to US Supreme Court decisions in 1992 in Quill v. North Dakota and 1967 in National Bellas Hess. If a vendor did not collect and remit the tax, the purchaser was still legally required to pay the state an equivalent "use" tax.
That changed in 2018 with the USSC decision in South Dakota v. Wayfair which ruled that states can mandate that businesses without a physical presence in a state with more than 200 transactions or $100,000 in-state sales collect and remit sales taxes on transactions in the state.
The result is simply a way to collect what's been due all along.
