If personal income tax (PIT) is not calculated for an employee, the reason is usually related to the settings of their personal data in the program. Tax accrual is handled by the system based on the entered parameters, and if something is specified incorrectly or left blank, the PIT calculation will not be performed.
What needs to be done
Open the employee's card and check the settings in the personal data section. This is where the parameters affecting the PIT calculation are stored — if they are filled in incorrectly or missing, the program will not withhold the tax automatically.
Carefully go through all the fields of the employee's personal data: perhaps some attribute, status, or parameter required for correct calculation is not specified. After correcting the settings, recalculate the accrual and check whether the PIT appears on the pay slip.
If the problem persists after checking and adjusting the settings, it is worth examining the specific fields in the employee's card in more detail — you may need the help of a specialist who can review your specific configuration and pinpoint exactly which setting is preventing the calculation.
