I have just realised that ive stupidly forgotten to inform the tax office that my hours had increased about a year ago. will i be in trouble or can i just inform them now and pay them back any money that ive mistakingly had last year. i'm a bit worried about ringing them.
That's quite a lot. I still wouldn't worry though. Just give them a ring and explain you'd forgotten. They'll take it from your latest award. Do it asap though because they could check how much tax you're paying and you don't want to look dishonest.
as my circumstances hadn't changed for ages i got used to them automatically renewing them. so it didn't cross my mind until a colleague mentioned it yesterday and i started to panic! i'll ring them.
thank you for all the advice everyone
