Hello

I'm starting out as a freelancer. I live in Japan and I am English. I will be working for agencies around the world but I don't know where I should register my trading name or how.

Additionally, what about tax / vat. For example, If I work for a British agency but I pay tax in Japan - what happens to the money the agency pay me?

Can anyone give me any pointers?
