Vinted asked for your National Insurance number
This is the sequence behind that prompt, in the order it happens. None of it is a penalty, and none of it is HMRC asking about you in particular.
- You pass one of the two floors, 30 or more sales of goods in the calendar year, or more than 2,000 euros of sales, whichever arrives first. Staying out of the report needs both to be true at once: fewer than 30 sales and no more than 2,000 euros. A great many pages print it the other way round, as though you had to cross both before anything was sent, which would leave a seller with 80 cheap sales believing they were invisible.
- Vinted asks you for the identifying details, gov.uk lists what a platform has to collect from an individual seller: full name, the address where you normally live, date of birth, and a “tax identification number (National Insurance number if you live in the UK)”. Vinted's help page puts the timing as “If you reach the thresholds for reporting, we'll reach out to you by the end of the year”, so the request lands well before anything goes anywhere.
- The report goes in January, It covers the calendar year just finished and reaches HMRC in the January after it. gov.uk describes the same timing from the receiving side, as reporting by the following January.
- HMRC receives figures, not a bill, What arrives is who you are and what went through the platform. gov.uk's own sentence about a platform passing your details on is “This does not automatically mean that you owe tax.” Nothing is calculated, charged or demanded by the report itself.
- Whether you owe anything is a separate, older question, It turns on what you were doing rather than on which site you did it on: selling things you owned and used, or buying and making things in order to sell them. That question predates every reporting rule on this page and is settled somewhere else entirely.
Two things this sequence does not contain. It never asks for a bank login, and it does not begin with an email: the request appears inside your Vinted account. Anything arriving by email and asking you to confirm bank details for HMRC is not this.
The same obligation, and which office ends up with it
One obligation, implemented country by country. Across the EU it is DAC7. The UK is not in DAC7: it runs the OECD model rules through its own digital platform reporting regulations, which land in the same shape. What decides which office ends up with your details is where you are tax resident, established from the address and the tax number the platform holds for you, and not the Vinted domain you happen to list on. gov.uk states the exchange plainly: “HMRC will share your information with your country's tax authority if you live in another country that follows these rules.” So a UK resident selling on vinted.de is still HMRC's, and a seller resident in the EU using vinted.co.uk is still inside DAC7. Checked 3 September 2026.
| Where you are tax resident | Who ends up with your details | The rule behind it |
| United Kingdom | HMRC | The UK's own digital platform reporting regulations, following the OECD model rules rather than DAC7 |
| Germany | Bundeszentralamt für Steuern | The Plattformen-Steuertransparenzgesetz, Germany's enactment of DAC7, in force since 1 January 2023 |
| Any other EU member state | That country's own tax authority, named in its own enactment | DAC7, which every member state has taken into national law |
Three things worth knowing about the shape of it. The report covers a calendar year and goes in the January after it, under the UK regulations and under DAC7 alike. The floor of 30 sales or 2,000 euros is a carve-out for sellers of goods only: services, and the rental of property or transport, have no minimum at all. And each platform counts its own sellers, so sales somewhere else are reported by that marketplace and are not added to your Vinted total to decide whether you cross.
Two calendars, and which one Cavri counts on
Platform reporting runs on the calendar year. UK Self Assessment runs 6 April to 5 April. They are different windows over the same selling, and a seller who reads one figure against the other will get two answers and assume one of them is broken. Almost nothing written about Vinted and HMRC flags it.
Cavri takes the window for its own export from the market the account is on: a vinted.co.uk account gets 6 April to 5 April, and the nine other Vinted markets Cavri serves get the calendar year. That is a fact about which dates go in the file, and not a statement about who receives a report or where you are resident. The practical effect is that the tax year picker on the Stats page hands a UK seller the window for their return, which is the wrong window for the platform report. For that one you type 1 January and 31 December into the two custom date boxes beside it. That is not obvious from looking at the screen, which is why it is written down here.
With a range on screen, Cavri shows how many items sold in it and what they took, which is the closest thing to a running position against 30 sales and against 2,000 euros. It is close and it is not the same number. Cavri counts items whose sale date it read back from your Vinted wardrobe; Vinted counts on its own basis and reports its own total. The second floor is stated in euros while a UK seller's takings are in pounds, at a rate Cavri never applies. Near the line, expect the two to disagree, and treat Vinted's figure as the one that decides it. What the export contains, column by column, is set out on Cavri's Vinted and tax page, linked at the foot of this one.
Whether any of it is taxable is a different question again, and an older one than any reporting rule. HMRC separates selling things you owned and used from buying or making things in order to sell them, and it publishes a tool that walks through it. One caveat almost nobody covers: selling a single personal possession for more than £6,000 can raise a capital gains question, which is very rarely a garment and is the honest qualifier on the flat claim that personal items are never taxed either way. Cavri has no view on which side of any of this you are on.
What this page and this software do not do
- None of this is tax advice, and Cavri is not an accountant. It is inventory software: it holds no authorisation to act for you, submits nothing and has no line to HMRC at all.
- It cannot tell you whether you are trading. That is HMRC's question, and it is answered on HMRC's side rather than in a spreadsheet.
- It does not know what Vinted will report about you. Cavri counts sales read back from your wardrobe, which is a good estimate of where you stand and is not the platform's own figure.
- It converts no currency. The second floor is written in euros and a UK seller's Cavri totals are in pounds.
- It cannot supply a National Insurance number, withdraw a request for one, or lift anything Vinted has restricted on an account.
- It only knows what it saw. Postage you paid, packaging, mileage and anything sold away from Vinted are all missing from it.
- Every figure here is right on the date this page carries. They move, which is why each one is linked below to the page that maintains it rather than only stated here.
Where each of these numbers is kept
Cavri maintains none of these figures and does not restate them as its own. Each link below is the page that does keep them, and the date on this page is when they were last read off it.
- Selling goods or services on a digital platform, HMRC on what a marketplace collects and reports, the two floors, the sentence about a report not automatically meaning you owe tax, and the sharing of details with the tax authority of the country you live in
- Vinted: HMRC requirements, what you need to know, Vinted's own account of the two floors, when it contacts affected sellers and what completing a report does not mean
- Tax-free allowances on property and trading income, the £1,000 trading allowance, its current figure, and when you are not allowed to use it
- The March 2025 announcement of the £3,000 threshold, the government's own wording: a Self Assessment reporting threshold rising to £3,000 gross within this parliament, with tax between £1,000 and £3,000 payable through a new simple online service
- Self Assessment: who must send a tax return, who has to file as things stand, which is the page the £3,000 change will land on
- Check if you need to tell HMRC about additional income, HMRC's own tool for the decluttering or trading question, which this page will not answer for you
- Capital Gains Tax on personal possessions, the chattels rule and the £6,000 point that the flat claim about personal items leaves out
- Council Directive (EU) 2021/514, known as DAC7, the EU half of the same obligation, where the 30 sales and 2,000 euro carve-out is written, and the reporting of sellers by the state they are resident in
- Plattformen-Steuertransparenzgesetz, the German enactment, and the law behind the German row of the table above
