FAQ
My 1099-K is way higher than what hit my bank. Which do I report?
Neither, exactly — you report gross sales and then deduct refunds, Amazon fees and reserves so the return reconciles to both the 1099-K and your deposits. That bridge is what clean books are for.
Amazon collects sales tax for me — do I still file anything?
Often yes. Marketplace facilitator laws cover Amazon's collection, but several states still expect a registered seller to file returns (even zero-due ones), and your own-site sales are entirely on you.
