Change address of moving home

Dear HMRC staff, Since I filed my return 2022/23 on Apr 2023 with my current address already, if I will move home later on, I have 2 questions to ask as below in both submission method: 1. If I submitted my tax return 22/23 already on Apr 2023 through HMRC website, since other figures and details remain the same, do I need to amend again by only updating my new address in whole self-assessment return 2022/23? Or just update the address in personal detail in my personal tax account in HMRC portal? 2. If my parents used 3rd party software to submit their tax return 22/23 already on Apr 2023, since other figures and details remain the same, do they need to amend their whole self-assessment return 2022/23 again through 3rd party software by only updating the new address? Or just update the address in personal detail in their personal tax account in HMRC portal? Thanks for advise.

Hi Keung C,

You would not be required to amend the tax return to update your new address.
This can be done in the HMRC account as you mentioned.

Thank you.
