Hi there, I'm a sole trader which is where I make all my income. I have been offered 2 days work through an agent and to do so I have to sign up to an umbrella company. Here's my question.. Does this make the umbrella my main employer and being a sole trader secondary? And if so how does this effect my tax free allowance, since I would only be making a tiny amount (one job) through the umbrella? The umbrella company seem like a bunch of robots not knowing how to give any answers on this.
