I came to the UK for good in 2021. I am completing the SA100 to apply for a Split Year Treatment, so that my part of the year before migrating to the UK will not be considered for tax. 2 questions please:
1) Can I leave Box 3 (page TR3) blank if my total foreign bank's interest is less than £2,000 during the UK-part of the year? I noted that I don't need to file a self-assessment if I fulfill the 3 bullet points in https://www.gov.uk/tax-foreign-income/paying-tax
2) Do I still need to complete SA102 if I already have paid tax through PAYE in my UK job which started after I arrived UK?
