(In the UK), I have, like some, an offline fulltime job - and have declared myself "self-employed" with the Tax Office for Google Adsense earnings.

Having not filled in a self cert tax form beofre, what kind of "things" can I claim back? Software purchased? Monitor purchased? New domains etc - and why "evidence" of purchase and for business use is needed?

Thanks
