The breakdown on your Form 1099-K specifically reports transactions that were swiped from the first through the last day of the month. Your statement is a reflection of all deposits made within the month reported. The Form 1099-K reports gross volume, meaning that it is not adjusted for credits, refunds, chargebacks, fees, reserves, etc. This form also does not include American Express ESA sales. A separate Form 1099-K will be mailed to you from American Express containing these sales.
