<p class=MsoNormal style='margin-bottom:12.0pt'><font size=2 face=Tahoma><span
style='font-size:10.0pt;font-family:Tahoma'>I'm currently studying <st1:country-region
w:st="on"><st1:place w:st="on">uk</st1:place></st1:country-region> tax, and I
was wondering whether drools would be suitable for calculating an individuals
tax liability.<br>
<br>
There are lots of rules such as:<br>
<br>
if age < 65<br>
then <br>
allowance = 5225<br>
if age >= 65 and age < 75 <br>
then <br>
allowance = 7550 - ((net income - 20,900) * 0.5)<br>
if allowance < 5225<br>
then allowance = 5225<br>
if age >= 75 <br>
then <br>
allowance =7690 - ((net income - 20,900) * 0.5)<br>
if allowance < 5225<br>
then allowance = 5225<br>
<br>
if 1=1 (run always)<br>
// calculate taxableOtherIncome (earnings, trading profits)<br>
taxableOtherIncome = otherIncome - allowance<br>
allowanceUsed = taxableOtherIncome - otherIncome<br>
allowanceRemaining = allowance - allowanceUsed<br>
allowance = allowanceRemaining<br>
<br>
// calculate taxableSavingsIncome<br>
taxableSavingsIncome = savingsIncome - allowance<br>
allowanceUsed = taxableSavingsIncome - savingsIncome<br>
allowanceRemaining = allowance - allowanceUsed<br>
allowance = allowanceRemaining<br>
<br>
// calculate taxableDividendIncome<br>
...<br>
<br>
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.<br>
<br>
Is drools suitable for this type of application?<br>
<br>
Many thanks,<br>
