How to register as self employed in the UK?

I would like to find out what should I actually do to register as self employed, well I mean could anyone give me any advice? Tips? On what to do etc? Someone with the experience? For example I'm not sure what to put down for the nature of my business? Internet Marketing? How do I go about tax etc? I've never really opened up a business before and need some good advice from someone with the UK experience.

Hi

I've just had to register self employed in the uk.

go to your local tax office, just google for it. they'll let you use their phones to ring up a number they give you. give them the information, name, address etc. takes about 10mins then they send u a national insurance bill and a few weeks later they send u the self assesment forms. It doesnt matter if you started trading/earning ages ago, you legally have 3mnths from when you started to register but i started 18mnths before i registered because i didnt know how to register and they gave me 100 pound fine and had to pay national insurance from the date i started, also i missed the self assesment deadline but you have 3 months from when the forms arrive so didnt get a fine for late filing. For the accounts get an accountant, mine charges 600 a year.

its really easy but if your earning over i think 37k you get 40%tax! Oh yeh and they need an exact date from when you started, i.e. day month year.

hope this helps, pm me if u have questions
