I really hope someone can help. I am a locum solicitor and have been self-employed for nearly two years. My tax is paid up to date and I have not had a problem with that. My latest assignment is with Sellick partnership who told me that I need to be with an Umbrella company to work for them. They put me in touch with Danbro who said they would charge me about £10 Pw for their services. Stupidly, I didn’t look any further into it and the firm wanted me to start asap so I signed up…Fast forward to my first pay slips and they taken a significant amount of money for what they term ‘ company deductions’ which include something called ‘employer margin’ and employment costs. They have declared my gross income to HMRC to be total money earned less these ‘employment costs’. In total I estimate I will lose nearly a third of all money earned this month to these costs. I also can’t claim any expenses anymore as I am classed as employed. Why would anyone use these companies and if I leave them will I have to give up the role with Sellick? Any advice much appreciated.
