I came to the UK in March 2019. Due to other formalities, my bank account was opened in April 2019. So in March 2019 my Indian salary got credited in an Indian bank account after tax deductions.
In April 2019, my salary was placed in a UK bank account and the balanced UK part on March salary as arrears.
So my April UK salary has April India salary, April UK allowances along with March UK allowance as arrears and March India salary as deductions.
UK tax deductions are beyond my calculations in April payslip.
So my question is: Is there any tax applicable on March arrears? If yes is it because of the fact that it is credited in April? Isn’t the double taxation on the same amount?
