Why Vinted, eBay and Uber Are Asking for Your National Insurance Number: HMRC's Platform Reporting Rules
By Tom Whitfield · Last updated 14 August 2026
Since January 2024, UK digital platforms — Vinted, eBay, Depop, Etsy, Airbnb, Uber, Deliveroo, Amazon Flex, Evri, Bolt and the rest — must collect their sellers' tax details (including National Insurance number) and send HMRC an annual report on anyone with roughly 30 or more sales or €2,000 (~£1,700) of income in a calendar year. That's why the "confirm your tax information" emails feel so insistent: the platform legally can't pay you out without the details. Being reported does not mean you owe tax — selling your own belongings stays tax-free — but if you're trading or gig-working above £1,000 a year and haven't registered with HMRC, the report will eventually surface it.
- The rules are the OECD's platform-reporting framework, UK-adopted from 1 January 2024; platforms file reports each January for the previous calendar year.
- Reporting threshold: 30 sales or ~€2,000 (~£1,700) in a calendar year, per platform.
- What's reported: your name, address, date of birth, NI number, gross income, fees the platform charged, and the bank account paid.
- A report is not a tax bill. Decluttering your own possessions is not taxable, whatever the volume.
- Tax applies if you're trading (buying/making to sell) or gig-working over £1,000 gross a year — the normal rules that always existed.
- Refusing the details request doesn't help: platforms must freeze payouts (and can withhold or close accounts) until you provide them.
What the emails actually are
Each platform brands the same legal requirement differently, which is why the emails look alarming and inconsistent:
| What you received | What it is |
|---|---|
| Vinted "tax information check" / "confirm your details" | Collecting your NI number for the annual HMRC report |
| eBay "seller verification" banner | Same rule — eBay can restrict selling until completed |
| Airbnb "taxpayer information" request | Same rule for hosts |
| Uber / Bolt "tax summary" documents | Your annual gross earnings — the same figures reported to HMRC, useful for your return |
| Amazon Flex "tax interview" | Amazon's version of collecting seller/driver tax details |
| Deliveroo / Evri "tax information check" | Same collection duty for couriers |
None of these mean you've been flagged, investigated or fined. They mean you crossed (or might cross) the 30-sale/€2,000 reporting line and the platform is doing its legal paperwork.
Who actually owes tax — a 30-second triage
| Your situation | Tax position | What to do |
|---|---|---|
| Selling your own clothes, tech, clutter — bought for yourself, sold second-hand | Not taxable, regardless of amount or sale count | Nothing. Provide the NI number when asked; keep the platform's summary emails |
| Buying or making things to sell; gig/delivery work — under £1,000 gross/year total | Covered by the trading allowance | Nothing to file; keep simple records |
| Trading or gig work over £1,000 gross/year | Taxable — Income Tax (and NI once profit alone passes £12,570) | Register for Self Assessment by 5 October after the tax year — see the step-by-step guide |
| One-off sale of a single item worth over £6,000 (art, jewellery, watches) | Possible Capital Gains Tax | Check the CGT calculator |
Not sure which row you're in? The Vinted and eBay pages walk through HMRC's "badges of trade" test, and the side hustle calculator shows what you'd owe if you are trading.
What HMRC does with the reports
The reports land each January and get matched against Self Assessment records. Where platform-reported income looks like trading and there's no matching registration, HMRC sends "nudge letters" inviting you to check your position and disclose. A nudge letter isn't an investigation — but ignoring one can turn into one, and penalties scale sharply once HMRC contacts you first. Disclosure before contact keeps penalties at their minimum, sometimes nil.
If you should have registered and didn't
- Work out the years affected and your gross income per tax year (platform statements make this easy now).
- Register for Self Assessment — the registration guide covers the steps.
- Tell HMRC about earlier years via the voluntary disclosure service rather than hoping they won't notice — they have the platform data either way.
- Estimate the damage first so there are no surprises — the side hustle or platform calculators give you the number in seconds.
Frequently asked questions
Is it safe to give Vinted my National Insurance number?
Giving it through the platform's own app or website settings is the legitimate request. Be careful of phishing: platforms never ask for your NI number by reply-to email or text link. Go to the app directly rather than clicking an emailed link.
I refused — now my payouts are frozen. Can they do that?
Yes. The regulations require platforms to enforce collection, and freezing payouts (or closing the account) is the standard enforcement. The details request doesn't go away; providing them is the only route to your money.
Does the 30-sale rule mean the first 29 sales are tax-free?
No — it's purely a reporting threshold and has nothing to do with what's taxable. A trader owes tax from £1,000 of gross income even with 10 sales; a declutterer owes nothing after 300 sales.
Do the platforms report to HMRC on the tax year?
No — reports run on the calendar year (January–December), while your tax runs 6 April–5 April. HMRC bridges the mismatch itself; you just declare your income by tax year as normal.
I got a nudge letter but I only sold my own things. What do I do?
Don't ignore it — respond using the letter's process confirming you weren't trading (personal possessions, no buying to resell). Keep any evidence handy: original purchases, the nature of the items. Genuine declutterers have nothing to fear from replying; silence is what escalates.
