Poshmark is now asking for social security information to send a 1099 tax form on used items I've already paid taxes on. Really! They already charge like 20% of what I make because they think they are professional and market your items ok whatever. So I suggest if you are selling used items switch to Facebook Market or Mercari. I'm sure Poshmark will loose most of its cliental with this request. Companies always have to up their so called game thinking it's the best choice however, this was a horrible move on a bad corporate idea. If poshmark is even that big.
