I was notified by HMRC that 2020/21 would be my last year for Self Assessment (I'm recently retired). I duly submitted one for that year. For 2021/22 I've checked and had confirmed that I am under the thresholds that would require a SA fo that year. That's fine, but where do I update e,g, dividends and interest for 2021/22. If its via my Personal Tax Account I can't find a page to update other than the current year 2022/23. My Dividend income for 2021/22 was less than £10k but more than £2k. I understand from the website that although this doesn't trigger an SA, I need to update HMRC. Going forward should I update my 2022/23 values and each subsequent year on my Personal Tax Account as soon as that financial year is concluded? Thanks
