I'm currently studying uk tax, and I was wondering whether drools would be
suitable for calculating an individuals tax liability.
There are lots of rules such as:
if age < 65
then
allowance = 5225
if age >= 65 and age < 75
then
allowance = 7550 - ((net income - 20,900) * 0.5)
if allowance < 5225
then allowance = 5225
if age >= 75
then
allowance =7690 - ((net income - 20,900) * 0.5)
if allowance < 5225
then allowance = 5225
if 1=1 (run always)
// calculate taxableOtherIncome (earnings, trading profits)
taxableOtherIncome = otherIncome - allowance
allowanceUsed = taxableOtherIncome - otherIncome
allowanceRemaining = allowance - allowanceUsed
allowance = allowanceRemaining
// calculate taxableSavingsIncome
taxableSavingsIncome = savingsIncome - allowance
allowanceUsed = taxableSavingsIncome - savingsIncome
allowanceRemaining = allowance - allowanceUsed
allowance = allowanceRemaining
// calculate taxableDividendIncome
...
There seems to be a fairly strict order to some of the calculations. I.e.
allowance should be deducted from otherIncome before savingsIncome or dividend
income.
Is drools suitable for this type of application?
Many thanks,
Chris
