I am an UK resident since June 2023 and i got some pending bonus from my previous company in czechia in march 2024 for working till may 2023 there. I came to UK first time last year and split residency applies to me. 1. czechia already deducted 15 percent tax on bonus. so, do i need to file a self assesment form and pay remaining 27 percent tax [42-15=27] here now considering i am in 42 percent tax bracket in scotland? 2. if i keep the money in chechia and dont bring to UK , do i still need to pay 27 percent tax here? If 2nd option is allowed to keep the money in czechia and dont bring to UK immediately, later when i will bring the money e.g. say in 2030, do i need to pay this 27 percent tax that time or it will depend on my income and income tax rate that time ?
