Depop Taxes and the 1099-K, Explained
This page explains what the 1099-K form is, why a marketplace sends one, and why the number on it can look alarming to a Depop seller in particular. It does not tell you what to do about your own taxes, because that depends on your circumstances and is a question for a tax professional rather than a selling guide.
Depop's seller base makes this question more common than it is elsewhere. A great many people selling there are clearing a wardrobe rather than running a business, which means the form arrives to people who did not think of themselves as sellers at all, and that is where most of the confusion comes from.
What the form actually reports
A 1099-K is an information return. Payment platforms and marketplaces use it to report to the tax authorities, and to you, the payments they processed on your behalf during the year. It is generated by the platform, and a copy goes to both you and the IRS.
The critical point is what it measures. A 1099-K reports gross payments processed, meaning the total that flowed through before fees, before shipping, before refunds and before what you originally paid for the items. It is not a statement of profit and was never intended to be one.
That single misunderstanding accounts for almost all of the alarm. Someone who sold clothes they bought years ago, at prices below what they originally paid, can receive a form with a substantial number on it that bears no relationship to anything they gained.
Why the Depop number can look odd specifically
Two things about Depop's structure affect how the reported figure reads.
First, the fee structure is unusually light. For US sellers there is no selling commission on eligible new listings and the cost is payment processing at 3.3 percent plus 45 cents. Because so little is deducted, the gross figure sits closer to what buyers paid than it would on a platform taking a large commission. Nothing is wrong; there is simply less of a gap.
Second, shipping and taxes are part of the base. Payment processing is charged on the item price plus shipping plus applicable taxes, and shipping the buyer paid is money that flowed through the platform. On low-priced clothing, where postage is a meaningful share of each transaction, that can inflate the total noticeably relative to what you would think of as sales.
Boosted listings add a further deduction that does not show on the form. The 12 percent boost fee on eligible new listings in the UK and US from 23 March 2026 is a real cost to you and is invisible in the reported gross.
What the platform cannot know
Depop has no idea what your clothes cost you. That purchase happened before the platform was involved, often years before, and frequently at retail. It is the largest number in the whole picture for most sellers and it appears nowhere in what gets reported.
That is why your own records are the only thing that distinguishes the reported total from anything meaningful. Useful records are the ordinary ones: what you paid for items and when, the processing fees deducted, any boost fees, shipping you covered, packaging, and refunds issued.
Platforms generally provide statements covering the fee and payout side. The part only you can supply is acquisition cost, and reconstructing that eleven months later is genuinely difficult in a way that noting it at the time is not.
Where a selling guide should stop
Thresholds for when a form is issued are set by the tax authorities, have changed more than once in recent years, and vary by circumstance. Whether any of this affects what you owe depends on your own situation, including whether your selling constitutes a business or occasional personal sales, and those rules are outside what a marketplace guide should be telling anyone.
So the boundary is this: understanding what the form is and why the number looks the way it does is useful, and that is what this page is for. Deciding what to do about it is a conversation with someone qualified to have it.
Bottom line
A 1099-K is an information return reporting the gross payments a platform processed for you during the year, sent to both you and the tax authorities. Gross means the total before fees, shipping, refunds and the cost of the items, which is why the number can look alarming while bearing no resemblance to anything you gained. On Depop this reads more sharply than elsewhere for two reasons: the fee structure is unusually light so less is deducted, and processing applies to the item price plus shipping and taxes, which on low-priced clothing inflates the total relative to what feels like sales. Depop cannot know what your clothes cost you, so your own records are the only thing that separates gross from meaningful, and what any of it means for what you owe is a question for a tax professional.
