Ignore the doom merchants. If you can manage the basic maths and you record all your spend in relation to your business an accountant won't save you money. If an accountant costs you £400 he will need to find £2,000 worth of costs to your business that you didn't find. Unless you are totally syupid, that is unlikely. However, if you don't want to do your own return or you find it too daunting, get an accountant. But it ain't difficult.
