To be honest, I wasn't aware I needed to do such a thing. I just assumed that I would supply my books etc., to an accountant after trading for a year for them to sort everything out. Sorry for being so naive.
Is it a big process to register?
Thank you for your reply and openness in your answer.You should register for self assessment as self employed within 3 months of becoming self employed. You can register for self assessment here
Once you have been issued with a UTR number, you should forward it to your customer and they wouldenable them to pay you for your invoices without tax deducted at source.In the meantime, the customer company is protecting them selves and also ensuring tax deducted is paid to HMRC.It is not a big process to register and you don't need an accountant to do this for you.If you get stuck, come back and I will help you here.
I hope this is helpful and answers your question.
If you have any other questions, please ask me before you rate my service – I’ll be happy to respond.
Many thanks for your kind help.
I will get back if I have problems registering.
