A Form 1099-K includes the gross amount of all reportable payment transactions.  You will receive a Form 1099-K from each payment settlement entity from which you received payments in settlement of reportable payment transactions.  A reportable payment transaction is defined as a payment card transaction or a third party network transaction.

• Payment card transaction means any transaction in which a payment card, or any account number or other identifying data associated with a payment card, is accepted as payment.  
• Third party network transaction means any transaction that is settled through a third party payment network, but only after the total amount of such transactions exceeds $20,000 and the aggregate number of such transactions exceeds 200.

The gross amount of a reportable payment does not include any adjustments for credits, cash equivalents, discount amounts, fees, refunded amounts or any other amounts. The dollar amount of each transaction is determined on the date of the transaction.

NOTE: The minimum reporting thresholds of greater than $20,000 and more than 200 transactions apply only to payments settled through a third-party network; there is no threshold for payment card transactions.
