This function calculates the Withheld Income Tax based on the employee’s gross income, including deductions related to dependent(s).

This tax is to be collected for the month in which the beneficiary receives the income.

Through the process Integration of Dependents the calculation of withheld income tax is integrated into the payroll.

During Customizing, parameters must be set for the following:

• Entry of amounts regarding income tax constants:
• Minimum income tax discount amount (included in MIINC)
• Income tax deduction amount for seniority (included in SEDED)
• Income tax deduction amount per dependent (included in TXDEP)
• Maximum age limit for income tax deduction for seniority (included in SENIO)
• Maintenance of the table of Income Tax deduction values
• Definition of special ranges of the table of Income Tax deduction values

The constants represented by monetary amounts (MIINC, SEDED, and TXDEP) can be found in the T511P view. In turn, these amounts are used by the BRIR function, which calculates the Withheld Income Tax discount. The main features of this function are:

1. When the PREP parameter is activated, it checks the Income Tax table and the information about dependents recorded in Infotype 0021.
2. When the TOLR parameter is activated, it transfers the last tax result.
3. When no parameters are activated, it calculates the tax.

The BRFIR feature is used for customizing new amounts of income tax deduction ranges, that is, it determines how the table will be read when new amounts are added by the user.
