I'm hoping to start up a small business. Nothing exciting, new, or ground-breaking. I have a sound technical background and hope to set up a small web hosting company (I already have a few people interested in buying hosting). I assume I can't just take cash payments and ignore the tax man. Could anyone explain the basic steps from going to a guy with an idea to a guy who runs a small company, ensuring that all legal/tax requirements are being met. If it helps: > I initially expect to be spending/earning no more than a few thousand a year (this is not my primary source of income, I see it as more of a hobby which should be able to sustain itself). > I am not allowed to 'carry on any formal or registered trade business or profession' at my home address. I don't know if this is a problem, can be ignored, or means I will need a PO box (I don't understand a lot of this). Any more information I can provide to help, please let me know.
