Educate me... because I might be missing something.
I am paid through various jobs, but all through PAYE, and I have no other incomes/huge savings/property etc. I have one main job, and then periodically I do bits of work for other large organisations that are all paid via PAYE - I definitely pay tax and NI on these.
Why then, have I just received a letter from HMRC telling me that I owe them over a grand? Where are the errors in my tax payment occurring? My main job puts me in the higher-rate bracket already, so I think I'm paying higher-rate tax on everything already. What am I doing wrong here? Should I give up, and just enter a self-assessment tax return each year to avoid these unpleasant situations? Should I hire an accountant?
I'm on maternity leave right now, and can't really afford this kind of bill. I assume that my tax code will be re-adjusted to pay it off, but I kind of resent the surprise (not paying it - I'm more than happy to pay what I owe - I'd just prefer not to receive a bill I can't afford).
