Compute a tax

You don’t need a tax object or taxList() to perform a calculation. Just call the top-level compute function:

<?php
include('taxes.php');
$amt = compute('OH',            // tax name
                2000,           // gross earnings
                0,              // ytd earnings
                $filingSingle,  // filing status (0=single)
                0,              // exemptions
                1,              // state exemptions
                12);            // pay periods per year (12=monthly)
print "Tax amt: $amt<br>";
?>
