Hi guys, I have a full-time proper job paying around £50K per year. In addition to this, an opportunity has arisen for me to earn a little bit extra as a freelancer. We're talking small amounts here - absolute most it would be during a full year is about £2,500 extra. Anyhow, I want to make sure I do things right with the tax man. Can anyone advise what I need to do? Do I have to register as self-employed and/or make any payments on account (I have read that self employed people make 2 payments on account throughout the year)? Do I need to do a tax return, and if so, how do I go about doing this? Do I need to start paying Class 2 NI contributions in addition to what I pay via my main employer?Any advice would be really welcomed please. I plan to call HMRC tomorrow to find out more. I would contact an accountant for advice, but it doesn't seem worth it seeing as we're talking about such small sums of money. But I do want to make sure I do everything properly.Thanks again.
