I am a PAYE tax payer suddenly asked by HRMC to submit tax returns for 2020/21, 2021/22 and 2022/23 - how do I do this? I have been through my HRMC account - all my P60s are in my account for these years. I have not changed employer during this period or done any other work. No help from HRMC chatbot or phone system which keeps kicking me out. Unclear guidance from HRMC on what to do. Do I now have to do self assessment for these 3 years? How can I do this retrospectively? The info would be as per my P60s. Any advice?
