I need some advice. A company I worked for untill 2019 is still on hmrc's system. When I left in early 2019 she issued my p45 and I moved on. Due to circumstances, I had to work reduced hours and needed to claim benefits.
I declared my earning. I was informed I would be entitled to much less and asked why I haven't declared the other place I work at. It turns out was told I am down as working in two places. I disputed this but HMRC has given me information to the effect that I had income from the former workplace in 2019/21. They started an investigation back in Jan but haven't heard back anything.
I spoke to the woman I worked for and she has not been helpful. I asked why she is paying someone who is using my NI. She said that's not true. I asked for a letter confirming when I left and the date of my last payslip. She wrote me a one sentence letter with no company logo or even her full name on it.
What can I do? I am planning to speak to my mp today but this has been very distressful. Shocking that HMRC is taking this long.
