HMRC Gets Your eBay and Vinted Sales Data: What It Actually Means

What actually changed, and what did not

On 1 January 2024 the UK brought in reporting rules for digital platforms — the UK implementation of the OECD Model Reporting Rules for Digital Platforms. The legal machinery is section 349 Finance (No.2) Act 2023, put into effect by SI 2023/817. The first reports reached HMRC in January 2025, covering calendar year 2024.

There is no "side hustle tax". That phrase is a press coinage, and HMRC has said so in terms: "There is no new tax for online selling." No rate changed, no allowance shrank, no new charge was created. What changed is HMRC's visibility.

Four "relevant activities" are in scope under HMRC's manual at IEIM901500, each where it is carried out for consideration:

• Sale of goods — eBay, Vinted, Depop, Etsy, Amazon Marketplace
• Personal services — Fiverr, Upwork, Deliveroo, TaskRabbit
• Rental of immoveable property — Airbnb, Booking.com, Vrbo
• Rental of a means of transport — car-sharing platforms such as Turo

Platforms report on the calendar year and must file by 11:59pm on 31 January following it. Calendar year 2026 therefore lands with HMRC by 31 January 2027. By that same date the platform must give you a copy of what it reported about you.

Does being reported to HMRC mean you owe tax?

No. This is the point the whole topic turns on, and it is where nearly every article goes wrong. GOV.UK states it plainly: a platform reporting your details to HMRC does not automatically mean you owe tax. HMRC's own Tax help for hustles campaign site is blunter still — being reported does not mean you necessarily owe anything or need to do anything.

The reporting threshold is not a tax-free allowance. It is a filing rule aimed at platform operators. Treating it as headroom is the single commonest error in this subject, and it fails in both directions. Keep the two questions apart:

Two examples make the independence obvious:

• Reported, owes nothing. You clear the loft and sell 200 items of your family's old clothing on Vinted for £900. You are comfortably over the 30-sale limb, so you are reported. You bought none of it to resell, everything sold for less than it cost, and you are not trading. Tax due: nil.
• Not reported, may well owe tax. You buy trainers at clearance prices and flip 12 pairs for roughly £800. Under 30 sales, under the value limb, so no report is filed about you. You bought stock intending to sell at a profit — that is trading, and if your gross receipts across all your side activities top £1,000 you have something to declare.

What is the platform reporting threshold, exactly?

The authority is HMRC IEIM901630, which lists four categories of "excluded seller" — sellers a platform does not have to report. The fourth is the one that matters to individuals. A seller is excluded only where the operator facilitated fewer than 30 relevant activities for the sale of goods and the total consideration paid or credited did not exceed EUR 2,000 during the reportable period.

The conjunction is and. Both limbs must be satisfied for you to escape reporting. Turn that round and the practical rule is:

The figure is in euros, not pounds. HMRC only ever converts it loosely — "about £1,700", "approximately £1,700". EUR 2,000 is the binding number, so the sterling equivalent drifts with the exchange rate. £1,700 is a rough translation, not a legal threshold, and the £2,000 you will see quoted on plenty of blogs is simply the euro figure with the wrong currency symbol attached.

The limb almost everyone misses: it only covers goods

Read the exclusion again and notice the four words that do all the work: for the sale of goods. The 30-sale and EUR 2,000 test exists only for goods. GOV.UK's operator guidance says so directly — the exclusion does not apply to services, transport rentals or property rentals.

There is no de minimis at all for the other three relevant activities. They are reportable from the first pound:

• An Airbnb host who let a spare room for two weekends and took £280 is reported.
• An Uber driver or Deliveroo rider who did four shifts is reported.
• A Fiverr or Upwork freelancer with one £60 job is reported.
• Someone renting out a car through a transport-rental platform is reported.

The reason is historical. The OECD's original 2020 rules covered services and property and transport rental. Second-hand goods marketplaces came in later, through a 2021 optional module — and it is that module that carries the small-seller exclusion. Consumer coverage almost universally presents "30 items or £1,700" as a universal trigger across every platform. It is not; it is a goods-only carve-out.

What actually decides whether you owe tax?

Three things, none of which mention a platform.

1. The £1,000 trading allowance. Statutory basis ss.783A–783AR ITTOIA 2005, in force since 6 April 2017, and confirmed still £1,000 for 2026/27 in HMRC BIM86000. If your gross trading income for the tax year is £1,000 or less, you do not have to tell HMRC or declare it. Above £1,000, you register and then choose to deduct either the flat £1,000 or your actual expenses — not both. Two traps: it is measured on gross turnover before costs, so £1,400 of sales with £900 of expenses breaches it even though the profit is only £500; and it is one £1,000 across all your casual trades combined, not £1,000 per platform. Our full guide to what the trading allowance is and how partial relief works covers the mechanics.

2. The badges of trade. Whether you are trading at all is decided by the nine badges set out in HMRC BIM20205: profit-seeking motive, the number of transactions, the nature of the asset, existence of similar trading transactions, changes made to the asset, the way the sale was carried out, the source of finance, the interval between purchase and sale, and the method of acquisition. HMRC's own caveat is that the badges will not all be present, and some may point each way — courts decide on the overall impression, following the summary in Marson v Morton [1986] 59 TC 381. Badge nine is the one that helps ordinary sellers most: goods acquired by gift or inheritance point away from trade. If your side activity is growing into something more, our guide to the journey from side hustle to full-time self-employment sets out where the line falls in practice.

3. Selling your own unwanted possessions is normally not trading at all. It is a capital disposal, and for tangible movable property (chattels) section 262 TCGA 1992 exempts a gain where the consideration does not exceed £6,000. That figure has been unchanged since 1989 and is still £6,000 for 2026/27. It applies per item or per set — matching vases, a chess set — not to your annual proceeds. Two further reasons ordinary second-hand selling produces no CGT: used clothing, furniture and electronics almost always sell for less than they cost, so there is no gain at all; and items with a predictable life of 50 years or less are exempt as wasting assets unless used in a business.

Put those three together and you have the real answer. If you are unsure where you land, our side-hustle Self Assessment checker runs the same logic — gross receipts across every activity, the badges of trade, and each separate Self Assessment trigger — and tells you whether you need to register.

Why the platform's figure will never match your tax return

You will receive a copy of what the platform reported. Do not copy it into a tax return box. It cannot be right, for two structural reasons.

The periods do not line up. Platforms report 1 January to 31 December. Your income tax liability runs 6 April to 5 April. A calendar-year figure spans the back half of one tax year and the front half of the next, so it can never equal any Self Assessment entry. A seller reported for calendar 2026 is looking at a number built from parts of both 2025/26 and 2026/27.

The basis does not line up either. The figure the platform shows you is your total earnings on that platform less fees, commission and taxes deducted — a net number. The £1,000 trading allowance is tested on gross receipts before any of that comes off. Sellers who compare the net platform figure with £1,000 will systematically underestimate where they stand, and some who believe they are under the allowance are not.

What happens if you miss the 5 October 2026 deadline?

Section 7 Taxes Management Act 1970 requires anyone chargeable to income tax or capital gains tax, who has not been issued with a return, to notify HMRC within six months of the end of the tax year. That is where 5 October comes from.

The live deadline is 5 October 2026, and it covers the 2025/26 tax year — 6 April 2025 to 5 April 2026. HMRC repeated it in a press release on 21 July 2026: new entrants to Self Assessment should register for 2025/26 by 5 October 2026. It is roughly six weeks away.

It catches more people than first-timers. It also applies to anyone who registered previously but did not need to file for 2024/25 and now does — that group may need to reactivate a dormant Self Assessment record through the same service.

• 5 October 2026 — notify HMRC that you need to file for 2025/26, at gov.uk/register-for-self-assessment. You will be issued a Unique Taxpayer Reference; leave time, because you cannot file without it.
• 31 October 2026 — deadline for a paper return for 2025/26.
• 31 January 2027 — deadline for the online return and for paying the tax. Our January 2027 Self Assessment checklist covers the filing run itself, and the autumn 2026 money checklist puts this deadline alongside the other dates competing for your attention this quarter.

Miss 5 October and the exposure is a failure to notify penalty. It is a percentage of "potential lost revenue" (PLR), and the percentage depends on your behaviour and on whether you came forward before HMRC prompted you. These are the ranges in HMRC's factsheet CC/FS11:

Notice what "unprompted" buys you: for a non-deliberate failure disclosed within 12 months, the floor is 0%. Once HMRC has written to you, the same disclosure becomes prompted and the floor rises to 10%. That is the concrete reason to act before a letter lands rather than after. HMRC also states that a reasonable excuse for a non-deliberate failure to notify means no penalty at all.

What should you do if an HMRC nudge letter arrives?

HMRC uses the platform data mainly for risk-profiling and "one to many" letters — standard-format letters sent to a group HMRC believes has undeclared income. A nudge letter is not an enquiry and not an assessment. It is a prompt, usually with a stated response window of around 30 days.

What to do, in order:

• Do not ignore it. The window is short, and silence invites a formal enquiry, which is a far worse conversation.
• Check it is genuinely from HMRC before doing anything else. This letter format is heavily imitated by scammers. Never respond via a phone number or link in the letter alone.
• Rebuild the actual figures for each tax year in question — gross receipts, re-cut to 6 April – 5 April, with fees added back.
• Work out whether you were trading against the badges of trade. Plenty of recipients were selling their own possessions and owe nothing; the correct reply in that case is a reply explaining that, not a disclosure.
• If you do owe tax, disclose and pay. Paying in full by the 31 January following the tax year keeps the failure-to-notify penalty base at nil.
• Recognise what the letter costs you. Receiving it converts any later disclosure from unprompted to prompted, which lifts the penalty floor off 0%. That is why acting first is worth real money.

Our detailed walkthrough of how to respond to an HMRC nudge letter covers the reply itself, evidence to gather and what happens next.

For scale: accountancy firm BDO reported in March 2026 — a secondary source, not an HMRC publication — that HMRC received income reports on close to 4 million online sellers for calendar year 2025, up from roughly 1.5 million for 2024, covering nearly £55 billion of platform earnings against £25.5 billion the year before. Treat the precise numbers with the caution any secondary figure deserves, but the direction is not in doubt: the dataset has grown several-fold and automated cross-matching against Self Assessment returns is being rolled out.

Common myths, corrected

• "There's a new side hustle tax." No. HMRC: there is no new tax for online selling. Only reporting changed.
• "The 30 item rule means 30 items makes you a business." No. Thirty sales is a reporting trigger for the platform. Whether you are trading is decided by the badges of trade, and one purchase made with intent to resell can be trading while 200 sales from your own wardrobe are not.
• "You're only reported if you exceed 30 sales and £1,700." Wrong way round. The exclusion needs both limbs, so you are reported on either.
• "The threshold is £2,000." No. It is EUR 2,000. HMRC's own rough conversion is about £1,700, and it moves.
• "£1,700 is my tax-free allowance." No. The only allowance is the £1,000 trading allowance, on gross receipts, on the tax year, across all your side activities combined.
• "The 30 items / £1,700 exclusion applies to Uber and Airbnb too." No. It is goods-only. Services, property rental and transport rental are reportable from the first pound.
• "The trading allowance is £1,000 of profit." No. It is £1,000 of gross turnover before expenses.
• "It's £1,000 per platform." No. It is one £1,000 across everything — £600 of photography plus £500 of sponsored posts breaches it.
• "I'm under the reporting threshold, so I'm fine." Not necessarily. A small buy-to-resell operation can be fully taxable and never appear in a platform report.
• "The CGT allowance is £6,000 so I'm covered." Two errors at once. The annual exempt amount is £3,000 for 2026/27; £6,000 is the separate chattels exemption, applied per item.
• "If HMRC has the data, they'll just tell me what I owe." No. The obligation to notify chargeability by 5 October is yours, and the penalty regime assumes you knew that.

What is changing, and what is not

Two forward-looking items get muddled into this topic. Neither is law today.

The Self Assessment reporting threshold, £1,000 to £3,000. Announced on 11 March 2025: the income tax Self Assessment trading income reporting threshold is to rise from £1,000 to £3,000 gross within this parliament, taking an estimated 300,000 people out of Self Assessment. Read the words carefully — this changes whether you file a return, not whether you owe tax; the government's own line is that people's tax liability will not change. The £1,000 trading allowance is not rising, and it was untouched at Budget 2025. No commencement date has been legislated, so any specific year you see quoted for it is speculation.

The OECD is consulting on the goods exclusion itself. A public consultation on targeted amendments to the Model Reporting Rules for Digital Platforms ran from 15 June 2026 to 14 August 2026, prompted in part by concern that the current design reports private individuals who are unlikely to owe anything — people selling multiple low-value second-hand items. Proposals under discussion include raising the low-value goods exclusion and removing the 30-transaction limb altogether. If adopted and then implemented in the UK, that would retire the "30 items" rule that dominates every search result on this subject. It is a consultation, not a change: nothing about the current test has moved.

Sources and methodology

The reporting framework and the four relevant activities are from GOV.UK's reporting rules for digital platforms and HMRC IEIM901500, with the legal basis in section 349 Finance (No.2) Act 2023 and SI 2023/817. The excluded-seller test is quoted from IEIM901630 in preference to the plain-English summary at Selling goods or services on a digital platform, for the reason set out above. Operator obligations, including the goods-only limitation, are from GOV.UK's operator guidance.

Liability rules: the trading allowance from HMRC BIM86000 and GOV.UK's tax-free allowances guidance; badges of trade from BIM20205; the chattels exemption from s.262 TCGA 1992 and GOV.UK on personal possessions; the £3,000 annual exempt amount from HMRC's CGT rates and allowances table.

Deadlines and penalties: notification under s.7 Taxes Management Act 1970 and gov.uk/register-for-self-assessment; penalty ranges from factsheet CC/FS11; potential lost revenue from Compliance Handbook CH72700. Volume figures for calendar 2025 platform reports are BDO's published analysis of 17 March 2026 and are labelled in the text as secondary. All figures checked against the sources above on 25 August 2026.
