Fear not! this isn't a rant about paying taxes for stupid things etc, more a question about my situation.
I currently work part time and pay tax as you generally do.
I start a new job in a week full time on a 3 month contract, full time hours, but I'll also be keeping my other job, but cutting it down to 1 day a week.
Just want to know how I go about making sure I'm paying the right tax/ the right amount/not too much, don't want to get taxed massively on the wrong job as it'll be a secondary income etc.
Or do I not worry about it and HMrevenue and Customs will notice my NI number is registered twice and figure it all out (not likely
) I'm aware HMR&C are pretty useless at times though, so just after some advice from people who've been int he same boat
