OnlyFans income is business income. That is the whole philosophy of this post: no euphemisms, no judgement, just the same tax treatment any subscription business gets — with two platform quirks that change the numbers, and a full worked calculation so you can see what a real year actually costs.

The basics: when you register, and by when

Subscriptions, tips, pay-per-view and custom content are trading income. Once your gross income from it passes £1,000 in a tax year, the trading allowance no longer covers you and you register for Self Assessment. The deadline is 5 October following the end of the tax year you crossed it in — so income earned in 2026/27 means registering by 5 October 2027, filing by 31 January 2028 and paying on the same date.

Note the word gross. OnlyFans deducts 20% of what fans pay before the money reaches you, and creators routinely report only what landed in the bank. That is the wrong figure twice over: the £1,000 test is applied to gross income, and understating turnover hides the point at which VAT becomes your problem. Record the full fan payment as income and claim the 20% as an expense. The profit is identical; the turnover is not.

What a real year actually costs

Worked example — £65,000 of fan payments, 2026/27. A sole-trader creator whose fans pay £65,000 across the tax year.

Income £65,000. Less the OnlyFans fee at 20% (£13,000). Less other allowable costs of £6,500 — camera and lighting, a fair business share of phone and broadband, a share of home costs for the room used for filming, editing software, and accountancy fees. Taxable profit: £45,500.

Income tax: the personal allowance is £12,570, so £32,930 is taxed at the 20% basic rate = £6,586. Class 4 National Insurance: 6% on profits between £12,570 and £50,270 = £32,930 × 6% = £1,975.80. Class 2 is treated as paid without payment because profits exceed £7,105. Total due: £8,561.80.

That is 18.8% of profit, and 13.2% of what the fans paid. It is almost always lower than creators fear. (Illustrative figures; the rates are the real 2026/27 ones.)

Now the part that pays for the accountant. Had that creator not claimed the £6,500 of legitimate costs, profit would be £52,000, tax £7,886 and Class 4 £2,365.80 — £10,251.80. Claiming them saved £1,690. At a 20% tax rate plus 6% Class 4, every £100 of genuine expense you fail to claim costs you £26.

Expenses that genuinely apply — and the ones that don't

Content equipment (cameras, lighting, phones, apportioned fairly for private use), props and outfits that are genuinely performance-only, a share of home costs for the space you film and edit in, software and subscriptions, platform fees, and accountancy fees. What does not qualify: everyday clothing, most cosmetic and grooming spending, and anything with a substantial private benefit — the creator expenses guide sets out the clothing rules in detail, because they are the ones HMRC challenges.

The VAT quirk, and where it actually bites

This is genuinely unusual, and it has been litigated. Fenix International Limited, the UK VAT-registered company that operates OnlyFans, argued it should account for VAT only on the 20% it deducts. HMRC disagreed and assessed it for £8,222,566 covering periods from 07/17 to 01/20, plus a further £3,015,912 for 04/20. The Court of Justice ruled on 28 February 2023 (Fenix International, C-695/20) that Article 9a of the VAT Implementing Regulation is valid — so the platform accounts for VAT on the full amount fans pay, not just its commission.

Practically: VAT on what fans pay is handled by the platform, not by you. Your own registration question is separate and turns on your own taxable turnover — compulsory registration at £90,000 on a rolling twelve-month basis, meaning any twelve consecutive months rather than your accounting year, with 30 days from the end of the month you crossed it to register. Because the supply chain here is a deemed one, get your position modelled before you are within striking distance of the line rather than after. The creator VAT guide has the detail.

The January that catches everyone: payments on account

Once your Self Assessment bill exceeds £1,000, and less than 80% of your tax was deducted at source, HMRC also collects next year in advance: 50% on 31 January alongside the bill itself, and 50% on 31 July.

Take the example above. The £8,561.80 for 2026/27 is due on 31 January 2028 — but so is the first payment on account of £4,280.90, making £12,842.70 payable that day, with another £4,280.90 on 31 July 2028. If your income genuinely falls you can apply to reduce the payments on account, online or on form SA303; reduce them too far and HMRC charges interest on the shortfall at 7.75% from 9 January 2026 (base rate 3.75% plus four percentage points). Our post on payments on account for creators works through the timing.

Undeclared years: fix them first, and fix them unprompted

HMRC has actively reviewed subscription-platform income, and platform reporting rules have made creator earnings visible by default since January 2024. If you have unfiled years, the Digital Disclosure Service is the route: you notify HMRC of your intention to disclose, receive a disclosure reference number, and then have 90 days to submit the disclosure and pay.

How far back you go depends on behaviour: 4 years where you took reasonable care, 6 years for careless behaviour, 20 years where it was deliberate. And the penalty gap is the reason to move now. For a careless inaccuracy, an unprompted disclosure can reduce the penalty to 0% of the tax owed; once HMRC has prompted you the floor is 15%. For deliberate behaviour it is 20%–70% unprompted against 35%–70% prompted, and coming forward voluntarily also keeps you off HMRC's published list of deliberate defaulters. The disclosure guide walks the process.

What to do this week

  1. Export your OnlyFans earnings statements for the tax year and record the gross fan payments, with the 20% fee as a separate expense line.
  2. Total your gross income for 6 April to 5 April. Over £1,000 and not registered? Register — 5 October after the tax year end is the deadline.
  3. List your allowable costs now rather than in January; at a 26% combined rate, forgotten receipts are real money.
  4. Work out your rolling twelve-month turnover and diarise a VAT review well before £90,000.
  5. Move a fixed share of every payout into a separate tax account, and add the payment-on-account uplift to your January figure.
