Hi all I am currently employed by a company where i work part time and self employed as i am registered as a sole trader for the freelance work i do. I have been doing some freelance work for a small design agency run by one woman who does most of the work herself. She has now asked me to become more involved and take over a large part of the design duties. She wants me to do this on a freelance basis still but my worry is that i will have problems with the tax office if a lot of my freelance income is coming from one place. I know there's the whole IR35 thing and they can try and class you as employed in certain circumstances which i don't want. Does anybody know how they decide if they want to class you as employed or self employed? Every site i look on seems to say different things and i don't really understand the IR35 rules, they don't seem to be very clear. I will still be getting some freelance work from other sources but this will probably make up the majority. A friend of mine seems to think that if 50% of your work comes from one place they will question self employment, has anyone experienced that? Thanks in advance.
