Hi uramakr1 Ramakrishnan,

Income Tax: general enquiries
We can provisionally cease the employment that is still incorrectly open, allowing us to update your code and restore at least some of your tax free allowance.
If you have your P45 from the previous employer, we can fully update and close the old employment, and fully restore your tax code, allowing us to issue any repayment due to you through your next wage.
Thank you.
