@Carlota1 Do you mean 1099? Since you are not an employee of Airbnb, you won't be getting a W2. Or a 1099 for that matter since Airbnb has changed its procedure and now only issues 1099K's to those hosts who have earned more than $20K and have had 200 or more payouts. Does that apply to you?
If not, you can easily find out how much you earned in 2015 by going to your Dashboard and under Host, go to Transaction History, then click on Earnings Summary in the red print. This will show your gross earnings, the Airbnb fees that were deducted and your net payouts. You can use this information for preparing your taxes.
