Basically the last year I have taken on some overtime, and I had a letter a few weeks ago advising my tax code has changed, so I thought nothing of it until today when I have been told I am now down £100 on my latest pay packet because of my new tax code.
Whats the procedure with this? is this the correct procedure, why wasnt my tax changed when I first started the overtime 8 months ago?
