"It's just a hobby" is the most expensive sentence in creator tax — because the line between hobby and business isn't about how it feels to you. It's about how it looks to HMRC.
The bright line: £1,000
The practical trigger is simple: total gross income from your creating passing £1,000 in a tax year. Under it, the trading allowance covers you — no registration, no return needed for that income. Over it, you normally register for Self Assessment whether or not you consider yourself 'a business'.
The character test: badges of trade
For edge cases — and for the question of whether you can claim losses — HMRC looks at the substance: Are you doing it regularly? Seeking profit (monetised channels, affiliate links, media kits count)? Operating in an organised way? A weekly upload schedule with a sponsorship rate card is trading; occasionally selling unwanted possessions on Vinted is not, no matter what the platform reports.
Why crossing the line isn't bad news
- Expenses become claimable — kit, software, home working: hobby spending becomes tax-deductible business cost.
- Losses can have value — a genuine trading loss in a build-year can often be relieved, sometimes against other income like your day job's PAYE. (Rules apply — this is one to do properly.)
- You look professional — brands increasingly ask for invoices and, sometimes, proof you're registered. 'Being a business' wins deals.
What to actually do
Passed £1,000 gross this tax year, or clearly heading there? Register by the 5 October following the tax year end, start a simple record of income (including gifted deals) and costs, and read the creator tax guide. Or skip straight to the £19 package and stop thinking about it entirely.
