I'm a comic artist in the UK. I earn money from my website, 3rd party merchandise sales and commissions. I've recently been commissioned to draw illustrations for an international magazine. They want my VAT number and other details so they can pay me online. I don't earn much money so I've never registered for VAT. Can they pay me without a VAT number? Do I need to register my business? Do I need to pay tax?
I'm lost so if anyone could help, I'd be very appreciative.
