I received form 1099-K which reports the total amounts of sales I made on EBay for 2017. However, EBay and Paypal took a combined 12.9% + .30 for each transaction. I contacted Paypal and explained my situation and was told to consult a tax professional. Paypal won't be sending a revised 1099-K since that correctly lists the gross income. There is no net amount box on the 1099-K form. I'm not itemizing deductions so how would I go about reporting the correct net amount of the income I actually received?
