Your First UK Self Assessment — The No-Nonsense Tax Guide for Freelancers, Gig Workers & Side Hustlers
HMRC's self assessment portal is confusing, the guidance notes read like they were written by robots, and Googling "do I need to do a tax return" sends you down a rabbit hole with no clear answer. This guide cuts through all of it. Written specifically for UK freelancers, gig workers, Etsy sellers, OnlyFans creators, tradesmen, and anyone earning outside of PAYE who needs to file their first self assessment — in plain English, without the jargon.
Who needs to complete a UK self assessment tax return?
If you earned more than £1,000 from self-employment, sold goods or services on platforms like Etsy or eBay, drove for Uber or Deliveroo, created content for income, or did any paid work outside a regular PAYE job — you almost certainly need to file a self assessment. This guide tells you exactly what applies to your situation and walks you through every step.
