Platform Reporting

Will Vinted, Etsy or eBay Report Me to HMRC?

Since January 2024, online platforms must share seller details with HMRC if you cross either of two thresholds. This checker tells you whether you'll be reported — and explains why being reported is a different question to whether you actually owe tax.

Casual Vinted seller — £400 of old clothes across 35 items

Vinted · £400 sales · 35 transactions

Reported, no tax owed. You crossed the 30-transaction threshold (35 items), so Vinted will share your details with HMRC at year end. But the £400 of personal items you sold at a loss isn’t trading income — under the £1,000 trading allowance and not classed as trading under HMRC’s badges-of-trade test. HMRC will see the report, see no Self Assessment, cross-reference, and (almost certainly) take no action. The pop-up asking for your NI number is the platform fulfilling its reporting obligation, not HMRC asking you for tax.

Etsy seller approaching the threshold — £1,500 sales, 18 items

Etsy · £1,500 sales · 18 transactions

Not reported (yet) but tax may be owed. Under both Etsy thresholds — £1,500 < £1,700 and 18 items < 30 — so Etsy isn’t required to share your details. But £1,500 is over the £1,000 trading allowance, so you owe Self Assessment regardless. Reporting and tax aren’t connected; this is the most-confused case.

Active reseller — £4,000 sales, 80 transactions

eBay · £4,000 sales · 80 transactions

Reported and owes tax. Both thresholds crossed by a wide margin. eBay will report; you owe income tax + Class 4 NI on the trading profit. Use the side hustle tax calculator for the actual amount.

In January 2024 the UK adopted the OECD’s Model Reporting Rules for digital platforms. Online platforms operating in the UK now have to do something they didn’t before: collect identifying details about their sellers and report that information to HMRC if certain thresholds are crossed.

The thresholds are deliberately broad. The aim isn’t to catch every casual user — it’s to give HMRC visibility into the part of the economy where genuine trading happens but doesn’t always show up on Self Assessment returns. The unintended side effect: a lot of casual users selling old clothes on Vinted have suddenly received pop-ups asking for their National Insurance number, panicked, and assumed they were about to be taxed on every fiver they made.

That’s the confusion this calculator exists to clear up.

The two thresholds

Reporting kicks in when either of these is true in a calendar year (1 January – 31 December):

More than £1,700 in total sales on the platform, or
More than 30 separate transactions

Whichever you cross first triggers the report. The platform must then collect your full identifying details (name, address, date of birth, NI number, tax residency) and share them with HMRC by 31 January of the following year.

What “reported” actually means

Being reported is a data event, not a tax event. The platform is fulfilling a legal obligation; HMRC is collecting data they’ll cross-check against Self Assessment returns. You receive nothing directly from HMRC because you’ve been reported.

Whether tax is owed depends on three other things, all separate from the reporting threshold:

Are you trading? HMRC’s badges of trade test. Selling your own old possessions at a loss generally isn’t trading; buying things to resell at a profit is.
If yes, are you over the £1,000 trading allowance? That’s the tax-free threshold for casual self-employed income. Different number, different framework.
If yes, what’s your marginal tax rate? Your day-job income, other income, and personal allowance all interact. The side hustle tax calculator handles this.

So the four possible outcomes for any seller:

	Trading, over £1,000	Personal items / under £1,000
Over £1,700 or 30+ items	Reported & owes tax	Reported, no tax owed
Under both thresholds	Not reported, but owes tax (Self Assessment still required)	Not reported, no tax owed

Most casual sellers landing on this calc are in the top-right cell — clearing out a wardrobe, panicking about a Vinted pop-up. Nothing to worry about beyond keeping a few records in case HMRC asks. The active resellers and side-hustlers are top-left, and they need to register for Self Assessment whether or not the platform reports them.

Why the calendar-year basis matters

UK Self Assessment uses the tax year (6 April – 5 April). HMRC platform reporting uses the calendar year (1 January – 31 December). They don’t line up. This calc uses the calendar year because that’s how the reporting rule is written. The tax calcs on this site use the tax year. Don’t add the two together — you’ll be looking at different time windows.

Per-platform, not combined

Each platform reports its own sellers independently. There’s no aggregation across platforms in the reporting rule. So you can sell £1,500 on Vinted, £1,500 on Depop and £1,500 on eBay — none of them individually triggers reporting, but your combined £4,500 of trading income absolutely does owe tax. Use the multi-platform tax aggregator for the combined-income view.

Common mistakes

Assuming HMRC reporting means a tax bill. It doesn’t. Reporting is a data exchange — HMRC gets your name, address, NI number, and total platform sales. Whether tax is owed depends on a separate test (badges of trade, gross income vs trading allowance, your other income). Selling personal items at a loss is not trading.
Confusing the two thresholds with each other. They’re an OR. £1,700 in sales OR 30+ items, whichever comes first. You can be reported with £200 of sales (if you sold 31 items) or with 5 items sold (if total sales were £2,000).
Counting items wrong. A bundle of 30 different items sold to one buyer is one transaction, not 30. The threshold is on transactions, not item-count-within-transactions. Vinted bundles are a common case.
Believing the threshold is per-platform but counting cross-platform. The £1,700 / 30-item rule is per platform per calendar year. Five platforms each at £1,500 means no reporting from any of them — but you may still owe tax on the £7,500 combined. Use the multi-platform tax aggregator for that side of the maths.
Refusing to give a platform your NI number. Once you cross the threshold, the platform must collect this. Refusing usually leads to account restrictions or freezes — and HMRC still gets reported (just with incomplete data, which makes them more interested, not less).

What this calculator doesn't cover

Per-platform check only. If you sell on multiple platforms, run this once per platform — each platform’s reporting obligation is independent.
Calendar year basis (1 January – 31 December), not UK tax year (6 April – 5 April). HMRC reporting follows OECD model rules, not the UK tax year. Self Assessment uses the tax year — they don’t line up. The site’s tax calculators use the tax year; this one uses the calendar year. Don’t double-count.
Doesn’t determine whether you owe tax — that’s a different test. The ‘tax implication’ line is a heuristic only. For the real number see the trading allowance and side hustle tax calcs.
Doesn’t handle non-monetary platforms (gift swaps, item trades, freecycle-style giveaways). The rules apply to platforms ‘facilitating relevant goods or services’ for consideration.

Frequently asked questions

Vinted is asking for my National Insurance number. Does that mean I owe tax?

No — but it does mean Vinted is required to share your details with HMRC. The two are separate. The pop-up appears once you cross 30 items sold OR £1,700 in total sales in a calendar year. HMRC then receives your name, address, NI number, and sales total. Whether you actually owe tax depends on whether what you’re doing is trading (in HMRC’s sense) and whether you’re over the £1,000 trading allowance. Selling personal possessions at a loss is not trading and not taxable, regardless of how many items or how much money — even if you cross the reporting threshold.

Why are there two thresholds — and why is it 'OR'?

The rules come from an OECD model designed to capture both high-volume, low-price sellers (Vinted clear-outs, eBay bulk sellers) and high-price, low-volume sellers (Airbnb, expensive antiques). A single threshold misses one or the other. Either trigger means a platform is doing enough volume that HMRC wants to see the data.

Are platforms doing this retroactively?

The reporting rules took effect 1 January 2024. Reporting is for activity from that date forward. Sales in earlier years aren’t included in the platform’s report (HMRC may already have data on those from other sources, but not via this rule).

What about platforms based outside the UK?

The rules apply to platforms that ‘facilitate transactions’ for UK-resident sellers, regardless of where the platform itself is based. So international platforms (Etsy, eBay, Airbnb) report UK sellers; pure UK platforms (Vinted UK) also report. The platform decides which seller is UK-resident based on registered address.

When does HMRC actually get the data?

Platforms must report by 31 January following the calendar year end. So 2026 calendar-year activity is reported by 31 January 2027. HMRC then cross-checks against Self Assessment returns due the same day. Late or missing returns from someone reported by a platform tend to attract attention.

If I'm reported but I genuinely don't owe tax, do I need to do anything?

Generally no. If your activity isn’t trading (you’re disposing of personal possessions), you owe no tax and have no Self Assessment obligation. HMRC will see the platform’s report, look for matching Self Assessment activity, and either (a) be satisfied that nothing is owed, or (b) write to you asking for clarification. If (b) happens, respond — explain that the items were personal property sold at a loss. Keep records (purchase dates, prices, photos if you have them) in case you need to evidence this.

Does this apply to my Etsy printable downloads / digital products?

Yes — Etsy reports UK sellers regardless of whether the products are physical or digital. Digital downloads are ‘goods’ under the rules. The £1,700 sales threshold and 30-transactions threshold apply just the same.

I sell across Vinted, Depop and eBay. How does that work?

Each platform reports independently. If you do £1,200 on Vinted, £500 on Depop and £600 on eBay, none of them individually crosses £1,700 — none of them reports. But your combined trading income (£2,300) is well over the £1,000 trading allowance, so you still owe Self Assessment if it’s trading income. The reporting framework doesn’t aggregate across platforms; the tax framework does. See the multi-platform tax aggregator for the combined-income view.
