Hi, i have been hired but at the same you i left as before it was only for a christmas temp job. i did not receive my P45 and still haven't received tax money back after getting in contact with you a while back. my new pay slip is tomorrow and again, ive been taxed. would you be able to give me a P45?? as i am being taxed by "emergency tax" and im only 17 with one job, and haven't earned my first £12,000.
