if you pay an accountant something in the region of £150-£200 to do your tax return what exactly does he do for you? if that's not a daft question...do they give you advice on record keeping (which presumably makes his/her job easier)? do they actively chase the figures they need from you? or do you have to give them near perfect records? do they advise you about what's tax deductable and what's not? and - a connected question - what proportion of your household bills do you claim (if any) and did your accountant advise you on this?
