Agree, it's not a new tax policy and sellers that operate a shop and sell often will know this. But as a hobbyist that might sell item one a month or so it is now being enforce upon. I have been selling on the other website and here for over 20 years and this year is the first time that I'm being tracked on things I've sold as a hobbyist and now I am receiving 1099 form. What's next - Craiglist, offerup and garage sale.
With that being said - I may or may not need to pay taxes on things that I sell, but I know things have changed and more money being pulled out of my pocket on items that I have already paid taxes on.
