Form 1099-K is the tax form most resellers meet first, and the one most often misunderstood. It is a report of payments, not a bill and not a profit statement. This manual explains what the IRS says the form covers, how it relates to what you report, and what to do when it does not match your records. It is general information from IRS pages, not tax advice. Thresholds and rules have changed several times in recent years, so check the current IRS pages for the tax year you are filing.
What the form is
The IRS describes Form 1099-K as a report of payments you received for goods or services during the year from payment cards, and from payment apps or online marketplaces, which the IRS calls third party settlement organizations. Those organizations must fill out the form, send it to the IRS, and send you a copy by January 31 of the year after the tax year (for example, early 2027 for the 2026 tax year).
If buyers pay you directly by credit, debit or gift card through your own card processor, the IRS says you will get a 1099-K from that processor no matter how many payments or how much they were for.
The marketplace threshold
For payment apps and online marketplaces, the IRS page says the platform must send a Form 1099-K if payments you received for goods or services total over $20,000 in more than 200 transactions (threshold in effect for the 2026 tax year). It adds that platforms may send a form with lower amounts or fewer transactions.
That threshold is a reporting rule for the platform. It is not a tax-free allowance for you. The IRS is explicit: whether or not you receive a Form 1099-K, you must still report any income on your tax return, including payments for goods you sell, and including personal items such as clothing or furniture sold at a gain.
Gross is not profit
The number in Box 1a is the gross payment amount. On its "what to do" page, the IRS says that amount is not adjusted for:
- fees
- credits
- refunds
- shipping
- cash equivalents
- discounts
It says these items are not taxable income and you can deduct them from the gross amount, and that your records are how you check. A payment reported on a 1099-K, the IRS notes, is not automatically taxable.
For a reseller, the gap between gross and profit is usually large. Marketplace fees, shipping you passed through, refunds to buyers and the cost of the items themselves all sit between Box 1a and your actual profit. The fees and margins and cost of goods sold manuals cover those pieces.
Personal items versus resale inventory
The IRS treats personal items differently from goods you buy to resell. On the 1099-K help page it describes a personal item as something you owned for personal use, such as a car, refrigerator, furniture, stereo, jewelry or silverware.
- Personal items sold at a loss. The IRS says a loss on a personal item cannot be deducted, but you can zero out the reported gross so you do not pay tax on it, either at the top of Schedule 1 or on Form 8949.
- Personal items sold at a gain. The profit is taxable and is reported on Form 8949 and Schedule D.
- Goods you sell as a seller. The IRS says gig workers, freelancers, hobby sellers and other self-employed people are considered sole proprietors and report 1099-K payment information on Schedule C.
The manual on personal sales or a business goes further into how the IRS frames that difference.
When the form is wrong
The IRS lists situations where you may get a form you should not have, including personal payments from family or friends, a form that does not belong to you, or a duplicate. Its steps:
- Contact the issuer named as "Filer" on the form.
- Ask for a corrected form, showing zero if the form should not exist.
- Keep copies of the original and all correspondence.
- Do not wait to file. File even if you cannot get a corrected form.
If the gross amount is incorrect and you cannot get a correction, the IRS says to report the amount from the incorrect form in the entry space at the top of Schedule 1. It also says not to contact the IRS to correct a 1099-K, because the IRS cannot correct it.
Payments from friends and family
The IRS says money received from friends and family as a gift or repayment for a personal expense should not be reported on a 1099-K and is not taxable income. Its examples include splitting a meal or getting repaid by a roommate. It suggests marking those payments as non-business in payment apps when possible. If you use the same app for sales and personal transfers, keep the categories clean; it makes reconciliation much easier.
A year-end reconciliation routine
- Download the annual summary or 1099-K from each platform.
- Total your own sales log by platform.
- Subtract refunds, fees and shipping you collected and paid out, using platform reports.
- Match the result to your records and note any difference with a reason.
- Keep the platform reports with your purchase receipts. The IRS recordkeeping page explains what to keep and for how long.
If the numbers still do not make sense, that is the time for a qualified tax professional. Bring the reconciliation; it makes the conversation shorter and cheaper.
My 1099-K shows more than I made. Do I pay tax on the whole amount?
Not necessarily. The IRS says the gross amount in Box 1a is not adjusted for fees, credits, refunds, shipping, cash equivalents or discounts, and that you can deduct those from the gross amount. Your records decide what you actually report. Taxable profit also depends on what you paid for the items.
