What a 1099-K does and does not mean

A 1099-K is a report from a payment app, card processor or marketplace showing what moved through your account during the year. It is not a statement of your income, and most of the work with one is turning that gross figure into the amount that actually belongs on a return.

What triggers a form for 2025

For 2025, a third-party settlement network reports when gross payments for goods and services pass $20,000 and the number of transactions passes 200. The 2025 law restored those figures after several years of lower announced thresholds.

Two things follow from that. Some people who received a 1099-K for an earlier year will not receive one for 2025. And plenty of platforms send the form anyway when they are below the threshold, because some states require reporting at much lower amounts and some processors simply report everything. A form you were not expecting is not evidence that you did anything wrong.

Card payments taken through a merchant account work differently. Those are reported by the processor without a dollar threshold, which is why a small shop with card sales receives a 1099-K even in a slow year.

Money from friends is not income

Personal payments are not income and do not belong on a return: splitting rent, settling up after dinner, a gift, a repayment of a loan. Apps ask the sender to mark a payment as personal or as goods and services, and that choice drives what gets reported.

A payment miscoded as goods and services can therefore land on your 1099-K even though nothing was sold. Ask the sender or the platform for a correction first. If no corrected form arrives, the amount still has to be accounted for, because the IRS has the same copy you do — your preparer reports the form and backs the personal portion out with an explanation, so the matching system sees the figure it expects.

Selling personal things

Selling a used couch, an old phone or a bicycle for less than you paid is not a taxable event. The loss is personal, so it is not deductible either.

Selling something for more than you paid is a gain, and gains are taxable: a collectible, a piece of jewelry, a resold ticket, a bike you restored. That goes on Form 8949 and Schedule D. The number that decides it is what the item originally cost you, so a receipt, a card statement or any reasonable record of cost is worth digging up before you assume there is nothing to report.

The gross number is too high

Box 1a is gross. It includes the platform's fees, shipping the buyer paid, sales tax the platform collected and passed to a state, and payments that were later refunded or charged back. None of that was ever money you kept.

Reconcile the form to your own books before it touches a return. Start with the box 1a total, subtract refunds, fees and pass-through amounts, and confirm that what is left matches the sales you recorded. On a business return you report the gross receipts and then deduct the fees and refunds as expenses, so the arithmetic lands in the same place — but only if those deductions are actually taken.

Where the number goes

• A business. Gross receipts on Schedule C, together with cash and any 1099-NEC income from the same work. Watch for double counting: one payment can appear on both a 1099-K and a 1099-NEC, and it is reported once.
• Personal items sold at a gain. Form 8949 and Schedule D, using what you paid as the cost.
• Personal items sold at a loss. Reported so the totals reconcile and then removed on Schedule 1, so the loss does not reduce your other income.
• Rent from a property. Schedule E rather than Schedule C, unless you are providing hotel-style services.

If the form is wrong

The forms are a matching tool. What keeps a return quiet is not leaving them out of the arithmetic, and what keeps the tax correct is your own record of what each payment actually was.
