When is the Payroll freeze Date every month in TCS?

20th every month

It's the 8th of every month, as per the HR policy. Any modifications post 8th, will be adjusted and credited as "arrear" in the next month.

I think it's the 12th of every month because my managers ask us to make sure to fill the night shift allowance data within that specified date so it gets reflected in the same month payslip.
