We're required by the IRS to report gross account transactions on tax forms. For each reservation, the gross amount is the price agreed upon before Airbnb service fees. Any refunds in the form of adjustments that took place after your initial payout for the reservation are not netted out of the gross amount displayed on your form.
If you received payouts for purposes other than a reservation, or sent payouts to a charity, they may be included in the gross earnings shown on your form as well.
To reconcile your gross earnings:
The CSV file can be opened by any standard spreadsheet program (like Microsoft Excel, Google Docs, or Apple Numbers) to give you a display of the data. Once open, filter the Type column (column B) to only show Reservations. The sum of the Gross Earnings column (column O) should reconcile to the amount reported on your Form 1099-K.
While we are required to report gross income on your form, it remains your responsibility to determine what, from your total amount earned, to report as taxable income on your US Income tax return. We encourage you to consult a tax advisor if you need assistance deducting any non-taxable income from your taxes.
