Not a resident for full year

Dear HMRC I moved from Australia to the UK in September 2021. I started work in the UK in November 2021 and have not received any foreign income since I moved aside from minimal interest on an Australian bank account (approx £300), which is taxed in Australia. I understand I still need to do a UK self assessment to declare this amount (which I have registered to do), but I am wondering if I have to disclose my Australian income/earnings from before I moved to the UK as well. If not, how do I make clear on the self assessment that a) I moved to the UK in August and b) that I paid tax in Australia? I want to ensure this is recognised so I’m not double taxed. Thanks in advance for any assistance!

Hi broadfurd13,

If you qualify for split year then you only report any foreign income for the UK part of the year:
RDRM12000 - Residence: The SRT: Split year treatment: Contents
If you do not qualify then you will need to report all your foreign income to the UK:
Tax on foreign income.  
The guidance at
RDRM12150 - Residence: The SRT: Split year treatment: Case 4: Starting to have a home in the UK only
will help you work out if split year treatment applies. 

 Thank you.
