@Jennifer-And-Garry0 This was one of my first questions for my tax guy when Air started collecting the taxes and not remitting them to me. He told me to track each booking and keep a spreadsheet of the amounts that were "paid" by AirBnB, and to continue to submit my monthly reports to the State and County for my income and the associated taxes with the explanation sheet stating that those amounts were paid by AirBnB. That is MY ONLY PROOF in the event of an audit.
I am not aware of any report, document or proof of payment that you can get from an OTA that your taxes have been paid.
