Thanks Nathan for "raising" this question. I too completed a "lot" of transactions (for me anyway) with Raise (and TPM) last year. AFAIK, I've not yet received a 1099-k from either platform/service, though I seem to recall Raise has/had a policy wherein they will send one out for high volume sellers who completed over 10k in sales. If indeed I get the 1099-K, I'm not sure what sponge_gto is asserting. My hunch is that the 1099K is not understood as a statement of "profit" per se, but a statement of gross sales completed. That's why we're to have detailed transaction records in order to tabulate profit/loss from each and all transactions completed during the tax year. Apart from the requisite record keeping involved, not sure why the tax reporting on this necessitates consulting a tax pro.... Yet curious to learn from other bulk sellers on their experience and practice. (even more so if you're in a state with a GRT -- e.g. Virginia, Ohio)
