Hi,
As you arrived in the UK in the 2022 to 2023 tax year, you were able to determine your residence status. This must be declared in a Self Assessment tax return, that included all of your UK income and capital gains.
For tax year 2023 to 2024, you will automatically be resident in the UK for the whole tax year, as a non domiciled UK resident. You will automatically be taxed on your worldwide income in the UK in each tax year. You would also have the option to claim the remittance basis, you can see guidance here:
Guidance note for residence, domicile and the remittance basis: RDR1
In either case, a Self Assessment tax return is required for each tax year you have foreign income or capital gains or claim the remittance basis. The deadline for paper tax returns for 2022 to 2023 was 31 October 2023. Any paper tax returns received after that date, are late and subject to penalties being imposed. Online tax returns can still be submitted on time up to 31 January 2024.
Please note the HMRC online tax return does not have a residence section, so cannot be used to sumbit a residence based tax return. You would need to be able to obtain a government gateway user ID and password. You can register below and set up a personal tax account, as well as register for Self Assessment:
HMRC online services: sign in or set up an account
For an online tax return that supports residence, you will need to buy a commercial software tax return and submit it with the government gateway user ID and password.
