OnlyFans taxes in the UK: a simple guide to declaring your income to HMRC

In the UK, OnlyFans income is self-employment income. Once your trading income passes the trading allowance, you register for Self Assessment with HMRC, file a return each year and pay Income Tax and National Insurance on your profit. Allowances, rates and dates change, so check gov.uk for the current tax year. This is not tax advice. Check the current rules with HMRC or an accountant.

What counts as income

Declare everything the account earns, from every source:

• Subscriptions
• Tips
• PPV messages and paid posts
• Custom content
• Merchandise and brand deals connected to the account

If you also earn from other platforms, that income goes on the same return. Keep each source labelled in your records so you can show where each figure came from.

Registering for Self Assessment

1. Check whether you need to register. HMRC has a trading allowance for small amounts of self-employment income. If your gross trading income for the tax year goes over it, you need to register. The current figure is on gov.uk.
2. Register as self-employed on gov.uk. HMRC sets a deadline for registering after the end of the tax year in which you started. Don't leave it late.
3. Keep your UTR safe. HMRC sends a Unique Taxpayer Reference after you register. You need it for every return. Keep it somewhere safe; HMRC and your accountant will ask for it.
4. Set up your online account so you can file and pay digitally.

Filing dates and payments

HMRC publishes the deadlines for paper returns, online returns and payment on gov.uk every year. Put them in your calendar the day you register.

• Online filing is the usual route and has a later deadline than paper.
• Payments on account may apply once you are established. HMRC can ask you to pay towards next year's bill in two instalments. Your return calculation shows it.
• Late filing and late payment carry separate penalties and interest. File on time even if you can't pay the full amount yet, and contact HMRC about a payment plan.

How much to set aside

You pay Income Tax on your total taxable income above your Personal Allowance, including this profit, plus Class 4 National Insurance on self-employed profit above a threshold. Both the bands and the rates are published on gov.uk for each tax year.

A workable habit:

1. Open a separate savings account for tax.
2. Move a fixed share of every OnlyFans payout into it as soon as it arrives.
3. Choose the share with an accountant, or by running last year's figures through HMRC's own guidance and calculators.
4. Review it when your income changes a lot.

Expenses and records

You can deduct allowable business expenses from your income, or use the trading allowance instead of claiming actual expenses. You can't do both against the same income, so work out which one leaves you better off.

Common allowable categories include equipment, software and editing tools, promotion, and a share of phone and internet used for the business. Read HMRC's guidance on "expenses if you're self-employed" before you claim working from home or wardrobe costs, as the rules are narrow.

Keep:

• Monthly earnings statements downloaded from OnlyFans
• Bank statements showing each payout
• Receipts for every expense
• A simple log: date, amount, category, note

HMRC expects records to be kept for several years after the filing deadline. Digital records are fine. Making Tax Digital for Income Tax started on 6 April 2026 for sole traders whose qualifying income for the 2024 to 2025 tax year was over £50,000, and lower thresholds follow in later years; gov.uk lists the thresholds and the tax year each one uses.

A note on VAT

VAT registration applies once your taxable turnover passes the VAT threshold, which is much higher than the trading allowance. Platform rules matter here too, so read OnlyFans' tax help pages and HMRC's VAT guidance, and get professional advice before you register or decide you don't need to.

Keeping records per creator

Agencies with UK creators need a clean per-creator trail, because each creator files their own return. In Inflowwww, per-creator earnings are at /analytics/creator-reports, and the message, PPV and tips log is at /analytics/message-dashboard. The OF Manager Statements screen is not built yet. For your return, use the official statements from OnlyFans.

The pitch. Self Assessment questions belong with HMRC and an accountant; Inflowwww is a free, self-hosted CRM and keeps no tax records. Deploy it yourself.
