Oh my, I'm already not liking this... Registering for VAT is going to leave me with almost no money at all

Thanks Alisonp! Still, they keep saying that I need to tell them my intracomunitary number, they keep telling me every day! Is there a website where I can apply online? I am really desperate!!

I have a similar problem. I send invoices from UK to Spain, and they say they want to know the VAT amount (but I make less, so I don't want to register) or give the my intracomunitary number, but it's nowhere to be found. What do I have to do?

Also, if someone could give me some help regarding the taxes, I'm new to this and I'm completely lost...
