Short answer. A 1099-K is not a bill and not a profit figure. Download the platform's transaction history for the year and sort every payment into four groups: business or side-income sales, personal items sold for more than you paid, personal items sold for less than you paid, and money that isn't income, such as gifts or a friend paying you back. Ask the filer to correct anything reported in error. Then report each group the way the IRS describes. Platforms that are third-party settlement organizations file a 1099-K when payments are over $20,000 and there were more than 200 transactions.
Why the total can be misleading
The IRS puts it plainly: "Just because a payment is reported on a Form 1099-K does not mean it is taxable." The form shows gross payments before fees, refunds, the cost of what you sold and anything personal. The reverse is also true: income that isn't on a 1099-K is still reportable.
The threshold for third-party settlement organizations, such as payment apps and online marketplaces, is payments over $20,000 and more than 200 transactions in the year, reinstated retroactively by the 2025 federal tax law. A platform may still send a form below that.
Step by step
- Check the form itself. Your name and taxpayer ID, the filer's name and phone number (upper left), and the gross amount.
- Download the full transaction history for the same calendar year from the app or marketplace, as a spreadsheet if you can.
- Tag every incoming payment with one of these labels:
- Business: sales of goods or services you sell as a business or side business.
- Personal, gain: a personal item sold for more than you paid for it.
- Personal, loss: a personal item sold for less than you paid.
- Not income: gifts, reimbursements for shared costs such as rent or a group dinner, refunds and transfers between your own accounts.
- Add up each group and make sure the four totals add back to the form's gross amount. If they don't, look for refunds, chargebacks or payments in a different calendar year.
- Fix anything reported in error. Contact the filer and request a corrected Form 1099-K. Keep a copy of every message. The IRS says gifts and reimbursements for shared costs "are not payments for goods or services" and aren't reportable on a 1099-K.
- Report each group. Business sales go on Schedule C along with the related costs and platform fees. A personal item sold at a gain is reported on Form 8949 and Schedule D. A loss on a personal item is not deductible; the IRS 1099-K FAQs show the proceeds and the cost (up to the proceeds) entered as offsetting amounts on Schedule 1, lines 8z and 24z. That FAQ is written for 2022 and 2023 returns, so check the current Form 1040 instructions or your tax software for the line to use.
If you can't get a corrected form
Don't hold up your return. The IRS describes reporting the amount received in error on Schedule 1 as other income on line 8z, labeled "Form 1099-K Received in Error," and the same amount as an adjustment on line 24z with the same label, so the net effect on adjusted gross income is zero. Keep your correspondence with the filer and your transaction history.
One seller's $23,480 form
A hobby jeweler who also sells things around the house gets a 1099-K for $23,480 from a payment app, covering 262 payments. The transaction history sorts like this:
| Group | Amount | What happens to it |
|---|---|---|
| Jewelry sales (side business) | $14,900 | Schedule C, with $1,190 of platform fees and $3,400 of materials as costs |
| Vintage guitar bought for $2,100 | $3,800 | Form 8949 and Schedule D: $1,700 gain |
| Used sofa and bike, bought for $2,600 | $1,300 | Personal loss, not deductible; offsetting entries as the IRS describes |
| Roommate's share of rent and utilities | $3,480 | Not income; ask for a corrected form, or zero it out on Schedule 1 |
The four groups add up to $23,480. The amount that ends up taxable is the jewelry profit and the guitar gain, not the form's total.
Next year: keep it cleaner
- Ask friends and family to mark personal payments as personal, not as purchases.
- Use a separate account or profile for business sales.
- Write a short note on each payment as it comes in: what it was for and who sent it.
- Keep receipts showing what you paid for personal items you later sell.

Common questions
Is the amount on my 1099-K my taxable income?
No. It shows gross payments. The IRS says a payment being on a 1099-K doesn't mean it is taxable; costs, fees, personal items and non-income payments are sorted out on your return.
Do I owe tax on a personal item I sold at a loss?
No tax on a loss, but the loss isn't deductible either. The IRS 1099-K FAQs show offsetting entries on Schedule 1 for the proceeds and the cost, up to the proceeds.
A friend paid me back through the app and it's on my 1099-K. What do I do?
Ask the filer for a corrected form. If you can't get one, the IRS describes reporting it on Schedule 1 as received in error on line 8z with an equal adjustment on line 24z, for a net of zero.
What is the 1099-K threshold for payment apps and marketplaces?
Third-party settlement organizations file when payments are over $20,000 and there were more than 200 transactions in the year.
If I don't get a 1099-K, do I still report my sales?
Yes. You must report all income you received, whether or not a form arrives.
