I am not receiving tax form (1099K) from Paypal because I didn't generate 20,000 of sales. This means that Paypal did not report those yearnings to IRS. Does that mean that I shouldn't count those earnings as my revenue for that year?
PayPal is required to report gross payments received for sellers who receive over $20,000 in gross payment volume AND over 200 separate payments in a calendar year.
