If you’re a UK-based OnlyFans creator, HMRC has almost certainly already received your earnings data for last year — whether or not you filed anything yourself. Since 1 January 2024, digital platforms operating in the UK have been legally required to collect and report seller information to HMRC annually, and the next submission, covering all of 2025, is due by 31 January 2026.
What OnlyFans is required to hand over
Under the platform reporting rules, OnlyFans and similar sites must report, for each UK creator: full legal name, date of birth, home address, National Insurance number or UTR, bank account details, gross consideration received (broken down quarter by quarter), and any platform fees withheld. Unlike the exemption that applies to people selling secondhand goods online, there is no minimum-transaction threshold for services — content subscriptions, tips and pay-per-view messages all count from the very first transaction.
The first report under these rules, covering 2024 activity, was filed by the 31 January 2025 deadline. The one covering 2025 activity is due by 31 January 2026, and HMRC is expected to start cross-referencing that data against individual Self Assessment returns during 2026 and 2027 — sending “nudge letters” to anyone whose declared income doesn’t match what the platform reported.
The dates that actually matter
- 31 January 2026 — OnlyFans’ second annual report to HMRC, covering your 2025 earnings, is due.
- 5 October 2026 — if your OnlyFans income first went over £1,000 in the 2025/26 tax year and you haven’t registered for Self Assessment, this is your registration deadline.
- 2026–2027 — the window in which HMRC is expected to begin sending mismatch letters based on the data platforms have already handed over.
Why this changes the calculation on “just not declaring it”
This isn’t a new tax or a new rate — it’s a change in how much HMRC already knows before you file anything. That has a direct, practical consequence: if you’ve under-declared or not filed at all, the sensible move is to get ahead of it. HMRC’s own penalty structure reflects this — a voluntary disclosure made before HMRC contacts you attracts a penalty of 0–30% of the tax owed, while the same error corrected only after a “nudge letter” arrives can attract 30–100%. The reporting requirement itself doesn’t change what you owe; it just makes the gap between what you declare and what OnlyFans already told them far easier for HMRC to spot.
This sits alongside the broader shift already under way for UK creators under Making Tax Digital for Income Tax, which is separately changing how higher-earning creators have to file. Between the two, UK creator income is now visible to HMRC from more directions than at any point since OnlyFans became a mainstream income source.
What to do now
- If you’re already registered for Self Assessment and filing accurately, this changes nothing practical for you — it just confirms HMRC has the same numbers you do.
- If you’re not registered, or you know your declared income doesn’t match reality, get advice on a voluntary disclosure before a nudge letter arrives rather than after.
- Keep your own records of gross earnings and platform fees separate from what OnlyFans reports, so any mismatch is easy to explain rather than discover for the first time in a letter from HMRC.
