I am a UK tax resident starting from June 2023 (date of arrival to UK) and I will apply for split year treatment for 23-24 tax year. After I arrived the UK, my Singapore employer continued to paid salaries for my remote support service from Jun until Aug 2023 when my employment ended. I had paid tax to the Inland revenue authority of Singapore in Aug 2023 once my employment ended. As there is a double treaty agreement between the UK and Singapore, is that mean I would not require to report this oversea incomes in the UK tax return 23-24 year ? Do I need to make a remark in the freehand notes box on SA100 "Any other information box ?" Thank you very much
