You need to take a view regarding the type of expenses your company will have too. I run a small, one man, UK Limited company and was for a time VAT registered.

You need to take a view regarding the type of expenses your company will have too. I run a small, one man, UK Limited company and was for a time VAT registered. This is because when I first started the company I spent a few thousand Pounds on equipment. All the VAT I paid on this equipment was able to be offset against any VAT I collected through invoicing. For a while I was ahead and it helped my cash flow, even factoring in the accountancy bills each quarter (which weren't really all that much). I made this move on advice from my accountant, and at the appropriate time, when I was no longer "ahead" on VAT, I was advised to de-register for VAT. My revenues still aren't £81k.
