Quick answer

If you are an individual creator living in the UK, the tax identification number a platform like OnlyFans asks for is normally your National Insurance number, not your UTR. HMRC rules require digital platforms to collect it and report your earnings each year. Giving it does not create tax, but it does mean HMRC will see your income.

Problems you face, answered

Not for this purpose. HMRC tells platforms to collect a UK individual seller's National Insurance number. Your UTR is your Self Assessment reference.

If the company is the registered seller, HMRC says a UK company's tax ID is its company registration number. If the account is in your own name, it is your NI number.

Tax explained

How OnlyFans Tax Identification Works

Why is OnlyFans asking for a tax ID now? Under HMRC's digital platform rules, which started in the UK on 1 January 2024, platform operators may need to collect seller details and report them to HMRC. For individuals, the tax identification number is the National Insurance number if you live in the UK. Find it on payslips, a P60, HMRC letters, the HMRC app or your personal tax account.

What does the platform report? Information is collected for each calendar year and sent to HMRC by the following January. It shows your earnings less fees and commission, and the platform must give you a copy. The exemption for fewer than 30 sales and under €2,000 applies to sales of goods, so creators selling content or services should not expect to fall outside it.

Does giving my NI number mean I owe tax? No. HMRC says the report does not automatically mean you owe tax. If your total trading income is over the £1,000 trading allowance, you generally need to tell HMRC, register for Self Assessment and file a return.

When do I need a UTR? You get a UTR when you register for Self Assessment. For income in the 2025/26 tax year you needed to tell HMRC by 5 October 2026; registering after that can lead to a penalty. Your UTR goes on your tax return, not on platform forms.

From our experience: Because HMRC will receive platform figures, the safest position is a return that matches the platform statement, with fees and expenses shown separately. If earlier years were missed, raising it before HMRC writes to you usually leads to a better outcome.

What to do when the platform asks

  1. 1

    Enter your NI number

    Capital letters, no spaces, if the account is in your own name.

  2. 2

    A company-registered seller gives its company registration number instead.

  3. 3

    Register for Self Assessment

    If your trading income is over £1,000 and you have not registered yet.

  4. 4

    Keep the annual statement

    Reconcile it with your records before filing your return.

Allowable expenses for content creators

How HMRC’s rules apply to content creators

If you are self-employed

Self-employed costs must be incurred wholly and exclusively for your trade. If you use the £1,000 trading allowance, you cannot also deduct actual expenses against that same income. Equipment treatment depends on cash basis or traditional accounting.

If you run a limited company

A limited company deducts costs incurred wholly and exclusively for its business. Equipment may need capital allowances rather than an immediate expense deduction. Personal use or company-paid private costs can create a taxable benefit or director’s loan entry; company ownership is not a blanket deduction.

For separable mixed-use costs, such as a phone bill, claim only the identifiable business proportion and keep evidence. This does not make ordinary clothing or every dual-purpose purchase deductible. A receipt alone does not prove a business purpose: retain the brief, invoice or usage record too.

Costs to review for your work

  • Business-use cameras, lighting, audio equipment and editing software
  • Editors, thumbnail designers, virtual assistants and licensed music
  • Travel to business shoots and the evidenced business share of home-working costs

Everyday clothing, ordinary grooming, personal meals, private gaming and fines are generally not deductible. Qualifying costumes or protective clothing and business-travel subsistence have different rules. Client entertaining is generally disallowed. Receiving a product from a brand does not automatically create an expense: record the income treatment separately and deduct only an allowable business cost.

Keep records alongside our creator expenses checklist, or discuss your costs with our bookkeeping team.

General UK guidance, not personal advice. The deduction depends on your facts and accounting basis.

No. Your NI number exists regardless, but you still need to register if your trading income is over £1,000.

Talk to us confidentially. A voluntary disclosure made before HMRC contacts you is usually the better route.
