I am wanting to sit down and do my tax return for last year. I was self-employed for a chunk of the year and had other PAYE jobs on the go too. This has made for a very complex tax situation. I called up HMRC and got them to send me a letter with all of my employers and tax paid. I noticed, however, that one of my employers was missing from the list. I am wondering why this is the case? Do they only show up at the tax office when a P60 is generated? This is annoying the heck out of me, as I know for a fact that I was overpaying tax in that job. I want that to come off my totals. I guess I better call my old workplace to get the information from them.
