Why doesn't my 1099-K match what I actually made?

Form 1099-K is the form a payment settlement entity must file for the payments it settled for you in a calendar year.^[1] In practice that means it is filed by payment card processors and by third party settlement organizations, which the IRS describes as payment apps and online marketplaces.^[2] It reports what passed through them for you, not what you earned.

• Payment apps and marketplaces report when the payments you receive for goods or services through the platform exceed more than $20,000 and more than 200 transactions in a calendar year.^[2] That is the threshold for calendar year 2022 and every year since: the One, Big, Beautiful Bill restored it retroactively to the date the lower $600 threshold would have started.^[3][4]
• Card payments taken directly from customers are reported by your card processor no matter how many payments or how much they were for.^[2]

So a seller on Amazon, Shopify Payments and PayPal can receive several forms, each showing a gross figure, and none of them showing fees or refunds.

The IRS states the gross amount on the form is not adjusted for fees, credits, refunds, shipping, cash equivalents or discounts.^[5] Every one of those is a normal part of selling online:

• Fees. Referral, fulfillment, payment processing and subscription fees come out before you are paid.
• Refunds. A sale refunded later still counts in the gross.
• Shipping charged to customers. Included in what the customer paid.
• Discounts and credits. Coupons and promotional credits change what you kept, not what the form shows.

Marketplaces also hold some money back as a reserve and release it later, so payouts lag sales. Add a payout that lands in January for December orders, a personal payment through the same app, or a second account under the same tax ID, and the gap between the form and the bank can look large even when nothing is wrong.

In the example, one month of Amazon sales for the demo store starts at 39,656.50 gross. After 1,236.50 of refunds, 7,203.40 of fees and a 412.75 reserve change, 30,803.85 reaches the bank, the same split you see when you record an Amazon settlement in QuickBooks. That 8,852.65 difference is the reason the form and the deposits disagree, and every dollar of it is explained.

PayPal and Venmo report payments received for goods and services. Paying friends or family back for dinner, a gift or a shared trip is not part of it.^[6][7] The IRS says payments made to friends and family for gifts and reimbursements should not be reported on a Form 1099-K.^[8]

• How a payment is tagged decides where it lands. On Venmo, every payment sent to a business profile is tagged as a purchase automatically; on a personal profile, the person paying chooses the tag.^[7]
• A personal item sold at a loss can still be in the gross. PayPal notes the gross amount it reports can include personal items sold at a loss, refunded amounts and processing fees, which may not be taxable income to you.^[6] The IRS treats a personal item sold for less than you paid separately from business sales.^[8]
• Mixed accounts blur the figure. If one account takes both, the IRS says to use your records to work out the amount of personal payments.^[8]

The clean answer for a seller is a separate business account or profile for sales, so the form's gross is business only, and books that record every business payment from that account at its gross amount.

There are two ways this goes wrong, and they push in opposite directions.

• Reporting only what reached the bank. Your return then shows less than the 1099-K the IRS also received, with nothing in your records to explain the difference.
• Reporting the 1099-K figure with no deductions. You overstate profit by every fee, refund and discount, and pay tax on money you never kept. The gross is before cost of goods sold, too.

The IRS points sole proprietors to Schedule C and says to use your books and records to work out your actual taxable income.^[5] That only works if the books start from gross sales and show each deduction, channel by channel. How the figures go on your return is your tax preparer's call; giving them books that tie to the form is ours.

Sometimes the gap is not timing or fees but an error on the form: payments that were not for goods or services, a duplicate account, or the wrong amount. The IRS says to contact the filer named in the top left corner of the form and ask for a corrected one, and notes that it cannot correct a Form 1099-K itself.^[5] Your reconciled books are what you use to show the filer where the figure is wrong.

If you get more than one 1099-K, sell on more than one channel, or have never matched a payout back to its orders, a 1099-K tie-out is part of what our monthly e-commerce bookkeeping does: gross sales recorded by channel, fees and refunds broken out, reserves tracked, and a year-end reconciliation from each form to the books for your tax preparer. If the year is already behind, start with what to do when you're months behind.
