Hi, I am in the process of completing a P85. My circumstances are that I worked in the UK last year, but for my last pay cheque, the company I worked for forgot to add on my overtime. The did, however, issue a P45. The outstanding amount was paid to me the following month (same tax year) with an emergency tax code, and no additional/replacement P45 was issued, despite my asking for it. In the section where I am asked about the earnings and tax paid as it appears on my P45, I can put in those numbers, but it doesn't reflect my total earnings/tax paid for that tax year. What do I do?
