I still fill out a self-assessed tax return, even though I've been employed for 3 years.
I filled it out using my P60, I don't have any savings or other earnings whatsoever.
The demand says I owe £1, but if I look at the working sheet accompanying it, its all zero. Would they really fine me £100 if I didn't pay it by 31 Jan?
It'd cost at least £1 in a phone call to find out what they're on about!
So I've paid it online...
