Hello, I work for an American company based on the UK. As an employee rewards, few years back I recieved stock options which were vested in the last financial year. During the process, a witholding tax of 47% were deducted and the money from the stock options process was transferred to my UK bank account. Question: 1-Which section I need to use for self assessment to declare these transactions? 2-UK and US have double taxation benefits, which shows a 15% max tax, is it possible to recliam the remainder tax paid and which section to complete for the tax reclaim? Self assessment page is like complex for an individual who have only one source of income. Please advise?
