Once a shop's sales cross the reporting threshold for the year, Vinted's payment processor issues a 1099-K — and like on every marketplace that issues one, a lot of sellers open it expecting to owe tax on the full number printed on the form.
What a 1099-K actually reports
A 1099-K reports gross payment volume — the total dollar amount processed through the platform in a calendar year, before fees, refunds, or anything a seller spent sourcing the inventory in the first place. It's a raw transaction total, not a profit statement, and the IRS receives a copy of the same figure — which is why it's worth taking seriously rather than setting aside.
Why the gross figure isn't the tax bill
Actual taxable income is gross revenue minus legitimate business costs: what was paid to source each item, shipping paid out of pocket, and any platform fees. A seller with a large gross 1099-K total and solid records of sourcing cost can owe tax on a fraction of that number — but only with documentation to back it up.
The gap that costs sellers real money
Sourcing receipts from thrift runs, storage units, or wholesale lots are the records that go missing most often — forgotten, lost, or never logged at the time of purchase. Without them, a seller either pays tax on money they didn't actually keep, or claims deductions with nothing to support them if it's ever questioned. Both trace back to the same fix: logging cost basis when an item is bought, not months later.
Building the record while listing, not at tax time
DepopAutomation.com's profit tracker ties a cost basis to each item up front and matches it against the sale price and fees the moment it sells — on whichever platform, including Vinted sales for sellers who cross-list from Depop. That produces a running, categorized record that sits alongside what a 1099-K reports, instead of trying to reconstruct sourcing costs from memory once the form arrives.
What this doesn't replace
An automated running total gets the math and the paper trail organized — it doesn't replace actually keeping sourcing receipts, logging standalone costs like packaging or storage, or having a CPA confirm the filing itself. It's the foundation the rest of tax prep sits on top of, not the whole job.
Conclusion
A Vinted 1099-K reports gross sales, not profit — and the difference between the two is exactly the sourcing costs sellers forget to track in the moment. Log cost basis as items are listed, and the form stops being a surprise every spring.
