Thanks for your reply.
As I see the notes of SA109 mentioned that "the resident arrive UK during this tax year" requires to fill in SA109.
I have checked that I am a tax resident for this year. Do I require to fill in SA109 if I arrive at UK within this tax year even if the case of split year treatment do not apply to my case?
I have an rent-out UK property and paid for the non-UK resident tax for last2 years. I move to UK this year and become a UK resident and I continue to own this rent-out property. Do the split year treatment applies to my case ? or any other attention I need to pay when I fill in the self assessment tax return?
