Hi FKRL,
Firstly, you will need to review the guidance at residence, domicile and remittance (RDR1)
Residence, domicile and the remittance basis: RDR1
From there you will need to review RDR3 (there is a link in RDR1) to determine your residence status and to determine if split year treatment applies in the 22/23 tax year.
From 23/24 you will be considered resident for the full tax year and all world-wide income will be reportable in the self assessment tax return.
In any case, as you have foreign income, you will need to register for Self Assessment.
You can do this her:
Register for Self Assessment
As you are not self employed, please ensure you do not select that option.
If using a paper tax return, the tax return SA100, is submitted along with SA109 (Residence) and any other relevant supplementary page, eg SA102 (employment), SA106 (foreign).
If your foreign bank interest is less than £2000.00, this can be entered on SA100 box 3.
If it is more than this, or you want to claim a Foreign Tax Credit, you need to declare on SA106.
The paper tax return must be in HMRC posession no later than 31 October 2023, to avoid late filing penalites:
File your Self Assessment tax return online
You can submit a tax return electronically.
To submit an electronic tax return with a residence section, requires that you purchase 3rd party commerical software:
(https://www.gov.uk/government/publications/self-assessment-commercial-software-suppliers).
The due date for an electronic submission is 31 January each year.
Thank you.
