1099-K box 1a, gross amount of payments.

What “gross amount” means

The instructions define gross amount as the total dollar amount of total reportable payment transactions for each participating payee without regard to any adjustments for credits, cash equivalents, discount amounts, fees, refunded amounts, shipping amounts, or any other amounts. The dollar amount of each transaction is determined on the date of the transaction. So box 1a is a count of what customers paid through the processor or platform, not what reached your bank account.

The third party network exception

A third party settlement organization (TPSO) reports information about third party network transactions of a participating payee only if, for the calendar year, both conditions hold: the gross amount of total reportable payment transactions exceeds $20,000, and the total number of such transactions exceeds 200. Both must be met, and the instructions say “exceeds”, so exactly $20,000 or exactly 200 transactions is not enough. The What’s New section of the instructions describes this as a changed reporting requirement. This de minimis exception is written for third party network transactions; the instructions do not extend it to payment card transactions processed by a bank or processor.

Who files and who is the payee

Every payment settlement entity (PSE), or other party that submits instructions to transfer funds to the account of a participating payee in settlement of reportable payment transactions, must file Form 1099-K for each participating payee for that calendar year. If an electronic payment facilitator makes the payments on a PSE’s behalf, the facilitator files instead of the PSE.

Worked example

An online seller completes 250 sales through a payment app in the year. Customers paid $24,500 in total. The seller later refunded $1,900 and the app kept $700 in fees. Box 1a shows $24,500: the refunds and fees are not subtracted. It is over $20,000 and 250 is over 200, so the app files. A second seller with 180 transactions totaling $30,000 meets the dollar condition but not the transaction count, so no third party network form is required for that year under the exception. The 1099-K is an information return; what you report as income on your own return is a separate question for your preparer.
