Moved abroad - P85 submission timeline?

Hello, I have 2 queries relating to moving abroad: 1. I recently moved abroad and have worked April of the current tax year (24_25). Do I need to submit my self assessment return for 23_24 before I submit a P85 with P45 details ? 2. I have updated my address online via Personal tax a/c /Profile and settings but there is no section to change my mobile number, Where can this be updated?

Hi CuriousP,
Yes you need to submit the return in event there is any tax due that can then be paid from any refund due for 24/25. To update your telpehone number for your online account, please telephone +44 16 1930 8445.
Thank you.

Thank you, I forgot to omit that i usually complete a self assessment return as had rent from an overseas property so in this case do i need to wait until the end of the tax year to submit my self assessment for 24_25 and then notify via this form it is my last return OR should i still complete a P85 now ( as i have completed my 23_24 return)? Many thanks.

Hi,

In this case, complete your 24/25 tax return next April, include the form SA109, and send your return by post. You can read more here:

Thank you.

Not HMRC...you do not need to submit a P.85 as you are under SA. When you complete the 2024/25 return you will need to complete residence pages to claim split year (if approrpriate). See "how to tell HMRC" https://www.gov.uk/tax-right-retire-abroad-return-to-uk. n.b. You should then also complete a SA return for 2025/26 to claim full non residence for UK tax purposes.
