Moved Overseas, late penalty notice

Hi, I moved back to Australia in March 2020, completed my 19/20 self-assessment on time and advised HMRC of my new address and that I would not be returning to the UK. I have since received notice that my 20/21 and 21/22 self-assessments are overdue and have incurred penalties. I didn't realise that I needed to complete self-assessment for those years, as I am no longer a tax resident. I used the chat function, and was told to just submit the return and then appeal the penalty afterwards. I was never sent any paperwork about my 20/21 assessment, just my 21/22 one, which is why it is a shock. But when I go into do it, it asks my tax residency - and only gives the option of England and Wales. I was not a tax resident so I don't feel comfortable submitting. Does anyone have any advice?

Hi,

If you appeal against the late filing penalties by completing form SA370 , it will be clear from the information you provide what your residency position is.

Thank you.
