i would i was warned by a customer that i could be due for inland revenue inspection. and explained that if i joined fsb covered for all accounting costs for inspections. joined up and following week letter drops thru door inspection in 2 weeks time. stuck there sticker up and i know this sounds incredible but tax inspector was really nervous once he spotted that i was a member (i think its because they know you can phone up for advise on inspectors decisions free of charge with fsb) the fact i had there support was real peace of mind. have asked them several questions since re tax rules the fsb knew more than my accountant, and got thru to there top adviser very easily and he really knew his stuff. you may join and not use for months but when you do it could be just the help you needed and the peace of mind is well worth it
