Made money from content? HMRC counts you as self-employed
There's a myth going round that creator income "doesn't really count" until you're big, or that platforms sort your tax for you. Neither is true. The moment you earn money from making content — subscriptions, tips, ad revenue, brand deals, affiliate links — HMRC sees a self-employed sole trader, and the responsibility to declare it sits with you, not the platform.
The good news: registering is free, it's not as scary as it looks, and doing it properly early is far cheaper than being chased later. This guide walks you through when you have to register, the one allowance that might let you off, and how to actually get set up and file your first return.
First: do you actually need to register?
You need to register for Self Assessment and declare your creator income if your gross self-employed income (before any expenses) in a tax year is more than £1,000. That £1,000 is the trading allowance — a flat tax-free amount for casual or side income. Under it, and with no other reason to file, you generally don't need to register at all.
Important detail creators trip over: the £1,000 is measured on your total takings, not your profit. If OnlyFans paid you £3,000 across the year but you spent £2,500 on kit and props, you're still over the threshold on takings, so you must register — even though your profit is only £500.
Quick gut-check: Add up everything every platform paid you in the tax year (6 April to 5 April), before fees and before spending. Over £1,000? You need to register. Under it, and it's your only income of this type? You're probably fine — but keep the records anyway.
The trading allowance vs claiming expenses
If you're over £1,000, you get a choice each year: deduct the flat £1,000 trading allowance from your income, or deduct your actual business expenses — whichever leaves you paying less tax. You can't do both. Bigger, more established creators with real costs (equipment, editing, a home studio, software, travel to shoots) almost always do better claiming actual expenses. Someone with tiny costs may prefer the flat £1,000. Our creator tax key dates guide has the calendar side once you're set up.
How to register with HMRC, step by step
- Get a Government Gateway account at gov.uk if you don't have one. You'll need your National Insurance number and some ID details.
- Register for Self Assessment as a sole trader. Search "register for Self Assessment" on gov.uk and follow the self-employed route. You'll describe your work — "content creator", "online creator" or similar is fine.
- Note the deadline. You must register by 5 October following the end of the tax year you started earning. Started earning in, say, June 2026? You register by 5 October 2027.
- Wait for your UTR. HMRC posts you a Unique Taxpayer Reference (a 10-digit number). You need this to file. It can take a couple of weeks, so don't leave registration to the last minute.
Watch this: Class 2 National Insurance is effectively abolished, but if you're profitable you'll usually pay Class 4 NI — 6% on profits between £12,570 and £50,270, then 2% above (check the current rate). It's calculated automatically as part of your return.
What your first Self Assessment actually involves
Once you have your UTR, filing is a case of reporting your income and costs for the tax year. In practice:
- Total your income from every platform. Payouts in USD or EUR get converted to pounds — declare the sterling figure you actually received. Tips, subscriptions, ad revenue and brand-deal fees all count.
- Total your allowable expenses — the genuine costs of creating content. Keep receipts and screenshots.
- File online by 31 January after the tax year ends, and pay what you owe by the same date.
Your first bill can feel steep because tax and NI land together, and if your bill tops £1,000 HMRC also asks for payments on account — advance instalments towards next year. That's not a penalty; it's HMRC smoothing your future bill, but it's a nasty surprise if nobody warned you. We break the whole calendar down in creator tax key dates.
Already earned and not registered? Don't panic
If you've been earning for a while and never told HMRC, coming forward voluntarily is far better than waiting to be found. Platforms now share earnings data with HMRC, so "they'll never know" is a bad bet. Read what to do about undeclared creator income — the penalties for putting your hand up first are much lower than being caught.
The honest bottom line
Register once you're over £1,000 of takings, keep every receipt and payout statement, and file by 31 January. Do that and you're compliant. Where it gets situation-specific — big earnings, going limited, VAT, crypto payouts — it's worth a proper conversation rather than guessing. Get started with us and we'll make sure the first return is done right, so it becomes routine after that.
