To complete the Self Assessment tax return for 6 April 2022 to 5 April 2023, you will need to declare on SA100 (tax return), SA102 (employment), SA106 (foreign) and SA109 (residence), your income and tax deducted from the date you arrived in the UK, to the end of the tax year.
Even if your pay is taxed under the PAYE system, it should be declared on SA102.
Your overseas income from interest, property, and any other source should be shown on SA106. You can claim a Foreign Tax Credit for up to 100% of any foreign tax paid on the income.
You also need to complete SA109, to claim split year treatment. All of this should be done in conjunction with SA100, which is the main tax return. You can download the tax return and supplementary pages here:
