The Marketplace 1099-K, Explained for Resellers

If you sell on Etsy, Poshmark, eBay, Mercari or Depop and a 1099-K just landed in your inbox with a number far bigger than you expected, take a breath. It's almost certainly not a bill, and it almost certainly doesn't mean you owe tax on that whole amount. A 1099-K is easy to misread, and misreading it is what causes the panic. The fix is understanding what it reports and keeping enough records to track marketplace expenses so you can subtract them. Let's walk through it in plain English.

What a 1099-K Actually Is

A 1099-K is an information return that a marketplace or payment processor files to report the gross amount it settled to you over the year. Think of it as the platform telling the IRS, "we passed this much money through to this seller." That's all it is.

Two things a 1099-K is not:

• It is not a bill. Nobody is asking you to pay the number on it.
• It is not your taxable profit. It's the top-line gross, before every cost that goes into a sale — fees, shipping, refunds, and what the item cost you.

Your job at tax time isn't to pay tax on the 1099-K figure. It's to start from that gross number and subtract your real costs to arrive at your actual profit — the part that's genuinely taxable.

Why Your 1099-K Looks Way Bigger Than Your Profit

The gap between the 1099-K and your bank deposits is normal, and it's usually large. A 1099-K counts the full amount buyers paid — including the shipping they covered — and does it before the platform deducts anything. Here's everything that comes out of that gross number before you see a profit:

• Platform fees — listing, transaction, and final-value or commission fees.
• Payment-processing fees — a percentage plus a fixed amount per order.
• Shipping — the postage and labels you paid for, even if the buyer "paid shipping."
• Refunds and cancellations — money that went back to buyers still shows in gross.
• Cost of goods — what you originally paid for the item you resold.

Subtract all of that and the profit left over is often a fraction of the 1099-K total. That's not a loophole — it's just how the form works. Creators hit the same wall with platform fees; our guide to 1099-K phantom income for creators covers that angle if you also earn from Patreon, OnlyFans or Twitch.

Selling Personal Stuff at a Loss vs. a Resale Business

This is the distinction that matters most, and it changes how the 1099-K affects you.

Cleaning out your closet. If you're selling your own used clothes, furniture or gadgets for less than you originally paid, that's generally a personal loss — not taxable income, and personal losses generally aren't deductible either. But you may still need to report and reconcile the 1099-K so the IRS doesn't assume the full gross was profit. Keep proof of what the items originally cost you.

Running a resale business. If you buy inventory to resell — thrift flips, wholesale, curated vintage — you're operating a business. You report your sales and deduct your cost of goods sold, platform fees, shipping and packaging to arrive at taxable profit. This is where consistent records earn their keep.

Plenty of sellers are a mix of both, which is exactly why keeping records matters — it lets you (or your accountant) draw the line cleanly. This is educational, not tax advice; confirm how your situation should be reported with a tax professional.

Platform by Platform — Etsy, Poshmark, eBay, Mercari, Depop

Every major marketplace issues a 1099-K on gross settled payments once you cross the reporting threshold. What differs is where you find the reports that let you reconcile it:

• Etsy — your monthly statements and the Finances / Payment account section break out listing, transaction, processing and ads fees. If you're an Etsy seller, our Etsy seller expense tracker guide goes deeper on the fee stack.
• Poshmark — fees are a flat amount on small sales and a percentage above a threshold; your sales report lists them per order.
• eBay — final-value fees and the Seller Hub reports show fees, shipping labels and refunds you can total up.
• Mercari — selling and processing fees appear on each sale; the sales history export is your source.
• Depop — selling and payment fees per sale, exportable from your receipts.

The common thread: the platform hands you the gross on the 1099-K, and it's on you to pull the fees, shipping and refunds back out. Downloading five different reports and reconciling them by hand is the tedious part — which is the whole reason to capture costs as they happen instead.

What Records to Keep So the 1099-K Isn't Scary

A 1099-K only feels threatening when you have no record of your costs. Keep these year-round and the reconciliation is a five-minute job instead of a January scramble:

• Cost of inventory — what you paid for each item you resold (or your materials, if you make things).
• Platform fees — from each marketplace's fee statements.
• Shipping — postage and label receipts.
• Packaging — mailers, boxes, tape, tissue, labels.

This is where a tracker earns its keep. ExpenseBot captures the fee statements and supplier and shipping receipts your marketplaces and vendors email you — plus any paper receipt you photograph — into one Google Sheet you own, categorized and ready to reconcile. It's the same ledger behind our ecommerce seller expense tracker, and it pairs your captured costs with your payouts in the income & expense tracker so you see the whole picture.

Reconciling the 1099-K to Your Own Numbers

Reconciling is just subtraction. Start from the gross on the 1099-K and work down:

Gross payout (1099-K)
− platform & processing fees
− shipping you paid
− refunds and cancellations
− cost of goods sold (what your inventory cost you)
= estimated taxable profit

That last line — not the 1099-K total — is roughly what your income tax and, for a business, self-employment tax are calculated on. The numbers here are estimates to illustrate the mechanics; confirm your actual figures and how to report them with your tax professional.

The threshold that determines whether you even receive a 1099-K has moved around in recent years and can differ by state, so always check the current IRS threshold rather than assuming last year's still applies.

Bottom line: a marketplace 1099-K reports gross, not profit. Keep your fees, shipping and inventory costs, subtract them, and the scary number turns into an ordinary bit of bookkeeping.
