Confusion about telling HMRC that I’ve left the UK to live abroad permanently

I’m confused about how to tell HMRC that I’ve left the UK to live abroad permanently. I am no longer a UK resident and I’m self employed. I left in Jan 2021, but have paid UK taxes via self assessment every year since as I was unsure if the move would be permanent and there was no way for me to pay tax abroad at that stage, and I was advised to ensure I’m paying tax somewhere so I kept paying UK tax. I’m now based abroad permanently and set up to pay tax here. I’ve already filed a P85 form. On the Gov.uk website, it looks like I also need to complete a self assessment with the SA109 section by post. I haven’t filed a self assessment for this year, I started to fill it out but I didn’t see the SA109 or any sections about living abroad, and at the stage of near completion it looked like I would be charged UK taxes just the same as previous years so I abandoned it. Do I need to submit anything else to let HMRC know I’ve left the UK permanently? Or is the P85 sufficient? Do I need to post an SA109 across the world or can this be done online at all? Thank you

Hi james123456789y,
If you have left the UK and do not need to complete a tax return, please complete the online form P85 at Get your Income Tax right if you're leaving the UK (P85).  
If you need to complete a tax return in the tax year you left the UK, you would need to include the supplementary page SA109.
Thank you.
 

Hello, its almost one year that me and my wife left the Uk..... How can I inform hmrc about that?

HI
Please see the guidance here: Tax if you leave the UK to live abroad

Hi! I'm self employed and about to leave the UK permanently. I submitted my self assessment tax return for 2023/2024, but cannot just yet do it for 2024/2025 (which is when I'm leaving). Will do it from abroad when HMRC unlocks it next year. Now I'm confused with the SA109 form, as it's asking me questions for 2023/2024 for which I have already sent the self assessment tax return. What do I do now? Thanks?

Hi L. Czekala,
You cannot submit the return until after 6/4/25 and the updated SA109 will be available then to tie in with the 24/25 dates.
Thank you.

I've never been a UK resident. Do I have to report to HMRC when I am living overseas permanently?

Hi, I will be leaving the UK permanently in January. Besides submitting the tax return and form SA109 after 6/4/25, does HMRC need proof (e.g. departure date, flight details) of the date I will actually leave the UK? Thanks

Hi,
If you have never been resident in the UK, then there is no requirement to nofify HMRC that you live permanently overseas.
Thank you.
 

Hi ,
 

If leaving the UK from P85 can be completed to inform HMRC : Get your Income Tax right if you're leaving the UK (P85)    . Thank you .
