Perhaps the UK citizens amongst you might like to take a look at this website.

It may not be exactly right for you if you are employed by EZY or RYR but it does give you some insight into the way HMRC works when dealing with individuals and small businesses.
You might also like to take a look here and note bullet point 6.

Most important is this page. It explains for instance, that RYR is a UK based company for all tax purposes, however unpleasant that fact might be!
http://www.direct.gov.uk/en/MoneyTax...UK/DG_10026136 Read this and the related pages carefully to see if you are taxable. Chances are, you are, were, and forever will be!
I hope this helps.
p.s. maybe we should open a Tax info thread?
