The days shopping tax-free with Amazon are coming to an end.
On Saturday Amazon will start collecting sales taxes on purchases in the last four states where it wasn't doing so: Hawaii, Idaho, Maine and New Mexico. Four other states -- Delaware, Montana, New Hampshire and Oregon -- have no sales tax, while a fifth, Alaska, doesn't have a statewide tax, but it does have municipal sales taxes.
Typically, an online retailer only has to collect sales tax in states where they have a physical presence, such as a storefront or a distribution center. That loophole cost states $17.2 billion in lost sales taxes last year, according to the National Conference of State Legislatures.
