Hi, As stated in my title, I work full-time in the UK in a permanent job, earning £33,000 per year. Between August and September this year, I worked on two projects on Upwork and earned $1,170, which is approximately £923.65. Do I need to declare this income for tax purposes? If yes, how should I go about it? If I don't need to declare it yet, at what point should I inform HMRC? Thank you.
