April 1st: Amazon will collect sales-tax in all states who require it

Starting April 1st in 2017, Amazon will collect sales tax on all states that collect sales tax. It is already doing so in the vast majority of the states, but with this latest group, it will complete the puzzle. It will obviously not collect sales tax in states where sales tax is not collected (Oregon, Alaska, etc). Details via CNBC.

But because things are never quite as simple, there is a distinction, for tax collection purposes, between products sold and shipped by Amazon (they collect taxes) and products sold by 3rd-party sellers through the Amazon website. The latter category is still up in the air as literally any and every person on earth (and beyond) can be an Amazon seller.
