I completed self-assessmnet returns each year for foreign income whilst living abroad for 4 years between 2018-2022, I have since returned and been in PAYE employment. I recently received a reminder to fill in a sel-assessment return if I was still required to (which I should not be). To be sure, I wanted to end any requirement to complete self-assessment. I have attempted numerous times to complete the 'Ending self assessment' form but every time It gets declined due to not recognising my previous address. I have attempted every variation of every single previous address that I can think of but it still gets declined for not recognising the address. Any suggestions for how to end it any other way?
