I've done a couple of small projects for my previous Web Development company. I hadn't done any freelance before. I'm not registered as a self-employed, nor as a Limited Company. I'm simply employed somewhere else now. I don't think I'll do any more freelance work.
I got paid the whole amount (stating VAT 0%) and was wondering if I should pay the included VAT? I'm not VAT registered. What do I do?
