Question

how to compute tax due if the taxable compensation income is P 118,999.60?

Answer 1

I'm sorry but your data is incomplete.  You must also give the following:

1.  Marital status of the employee/taxpayer;

2.  Number of children, if any; and

3.  Whether the amount of P118,999.60 was earned prior to implementation of RA 9504 that is on July 4, 2008.
