I have to set up a tax called "Tax 17.5 "
It consists of 3 children taxes
'Getfund 2.5' = 2.5% of base amount
'Nhil Levy 2.5' = 2.5% of base amount
'VAT 12.5' = 12.5 of (base amount + (getfund2.5 + nhillevy2.5))
Sample Calculation:
base = 6589
getfund2.5 = 2.5% of 6589 = 164.73
nhillevy2.5 = 2.5% of 6589 = 164.73
vat12.5 = 12.5% of (6589 +(164.73+164.73))
= 12.5% of (6589 + 329.46)
=12.5% of 6918.46
=864.81
Total Tax(17.5) = getfund2.5 + nhillevy2.5 + vat12.5
= 164.73 +164.73 + 864.81
=1194.27
How can I achieve this?
