NTX tax code

I recently moved to Dubai where I am working. My tax code changed to NTX a month later. I was still paying tax up until then. Is there a way that I can have my tax refunded in my next payslip or do I have to wait until next year for a rebate? I was told that if they remove the X in the my tax code then I will be refunded all of the tax I have paid this year and I will have to pay back what I am owe next year. Is that correct?

Hi,

The "NTx" tax code is correctly being applied, as you will be taxable on your UK employment income up to the date you left the UK. The "NTx" will ensure that your employer does not repay all the tax deducted from the 6 April 2023. You will need to complete a Self Assessment Tax Return after 5 April 2024, to claim back any overpaid tax prior to NTx being applied.

Thank you.
