I would like to setup income tax calculations using tax slabs. Our income tax calculation is as follows:
Annual Income Annual Income Tax
P0 – P36,000 P0
P36,001 – P72,000 5%
P72,001 – P108,000 P1,800 + 12·5% of excess over P72,000
P108,001 – P144,000 P6,300 + 18·75% excess over P108,000
P144,001 and above +P13,050 +25% of excess over P144,000
How do add formulas on the tax slabs to achieve this?
