The quiet rule change that reshaped creator tax: since 1 January 2024, digital platforms operating in the UK have had to collect information about the people earning money through them and report it to HMRC. The first reports were filed by 31 January 2025, covering calendar year 2024. The second landed in January 2026. By the time the January 2027 reports go in, HMRC will hold three consecutive calendar years of creator earnings data.

Nothing about the tax rules changed. What changed is detection — and one detail that catches out even creators who file properly, because the platform's numbers will never match your tax return.

What platforms actually send HMRC

The report is not a vague summary. Platforms collect and pass on your name, address, date of birth and tax identification number — your National Insurance number, if you are a UK individual — alongside your income through that platform, broken down by calendar quarter and net of any fees the platform deducted.

The platform must also give you a copy of what it reported. That copy is the single most useful document in creator bookkeeping and almost nobody downloads it. Get yours: it tells you exactly what HMRC has been handed, in the exact shape they have it.

The exclusion, and why creators almost never qualify

There is a genuine small-scale exclusion, and it is narrower than the headlines suggested. Your details are not reported if you make fewer than 30 sales of goods in a calendar year or receive less than €2,000 (about £1,700) for those sales.

Read that again: sales of goods. Selling a few second-hand bits on Vinted or eBay is what it was written for. Ad revenue, sponsorships, subscriptions, affiliate commission, tips and paid services are not sales of goods, and no equivalent exclusion applies to them. If you earn from content, assume you are reported.

The mismatch that causes the letters

Platforms report by calendar year, 1 January to 31 December. You are taxed by tax year, 6 April to 5 April. The two figures cannot agree, and a creator who copies the platform's annual total onto their return has filed a wrong number in both directions.

Worked example — reconciling one year. A creator's platform copy for calendar 2026 shows gross earnings by quarter: Q1 £4,800, Q2 £5,900, Q3 £6,400, Q4 £7,500 — £24,600 for the calendar year.

Their 2026/27 tax return covers 6 April 2026 to 5 April 2027. That is Q2, Q3 and Q4 of 2026 (£19,800) plus Q1 of 2027 (say £8,100) = £27,900 — £3,300 more than the platform's calendar figure, from the same account.

Two further adjustments. The quarters do not split cleanly at 5 April, so the first five days of April 2027 belong in the following tax year and only your own records can separate them. And the platform reports net of its deductions, whereas you declare gross income and claim the platform's fee as an expense — the same profit, but a turnover figure that matters for the VAT threshold. (Illustrative figures.)

This is why keeping your own records across platforms is not optional busywork. The platform copy is a cross-check, not a substitute.

What hasn't changed: the £1,000 trading allowance

The trading allowance is £1,000 of gross income per tax year, measured before expenses. Under it, you need no registration and no return for that income. Over it, you register for Self Assessment by 5 October following the end of the tax year in which you crossed the line.

You will have seen headlines about £3,000. In March 2025 the government announced that the Self Assessment reporting threshold for trading income will rise from £1,000 to £3,000 gross within this Parliament, taking around 300,000 people out of filing a return, with a new simple digital service instead. Two things about it: it has not started, and it is a reporting threshold, not a tax exemption. Income between £1,000 and £3,000 would still be taxable — just declared a different way. Until the service exists, the £1,000 rule is the one that binds. Our creator tax guide tracks it.

And what's coming: Making Tax Digital

Making Tax Digital for Income Tax started on 6 April 2026 for sole traders and landlords with qualifying income over £50,000, tested on the 2024/25 tax return. It extends to those over £30,000 from 6 April 2027 (tested on 2025/26) and over £20,000 from 6 April 2028 (tested on 2026/27). Qualifying income is turnover, not profit — a creator grossing £55,000 and netting £30,000 is in the first wave. HMRC writes to you when its review of your return puts you over. Our post on MTD for creators covers what quarterly updates involve.

What it costs to have waited

If you have undeclared years, the difference between coming forward and being found is measured in percentages of the tax owed. For an inaccuracy HMRC treats as careless, an unprompted disclosure can reduce the penalty to 0%; once HMRC has prompted you, the floor is 15% and the ceiling 30%. For a deliberate inaccuracy the range is 20% to 70% unprompted against 35% to 70% prompted. Coming forward first is worth real money, and it also keeps you off HMRC's published list of deliberate defaulters.

What to do this week

  1. Download the reported-information copy from every platform that pays you. Keep them with your records.
  2. Add the gross figures across platforms for the tax year — 6 April to 5 April — not the calendar year.
  3. Above £1,000 gross and not registered? Register for Self Assessment; the deadline is 5 October after the tax year end.
  4. Over £50,000 of turnover? Check whether you are already in Making Tax Digital and check quarterly-update software.
  5. Undeclared years behind you? Start a voluntary disclosure now, while it is still unprompted — see our guide to catching up with HMRC.

The era of platform income flying under the radar is over. The good news is unchanged: declared income with properly claimed expenses usually costs far less tax than creators fear. The people who lose are the ones who wait to be asked. Get started with us from £19 + VAT a month.
