I am currently a non tax resident but I will return to take up employment in the UK from 1 November 2024. My annual salary from new UK job will be 120k but since I will be joining the company on 1 November only 50k of my annual salary will fall in tax year 24/25 which means I should receive full Personal Allowance of 12.75k. However if my UK employer uses my current tax code it will be based on my annual salary giving me reduced PA? Should I ask HMRC to issue a different tax code for the 5 months of this tax year and then revert to normal tax code from 6 April 25?
