For me paying accountants to do this is some of the best money I spend every year.
Some of the worst money I spend every year is the fecking cheque made out to HM Revenue and Customs that I signed today. I nearly shed a tear. Still I'm sure Mr Darling will spend it wisely. Mmmmm.
As for how much accountants/tax consultants cost is not the best way to judge them - it's better to look at the value...mine cost 10% of what he and his team saved me with their cunning and guile (all legit and above board of course).
use an accountant now, doing it myself just took too long......................then I set up a limited company..........................................................., which has now closed but he still does my accounts because, the IR demand I fill whatever forms are needed, because I have ticked a particular box and as such I must complete self assessment returns.......................................
