Answer:
No. Workers comp does not calculate like a tax where you can have deductions that reduce taxable income (and the amount). Workers comp will calculate only on gross earnings. No taxes will modify the calculation.
If you need to calculate workers come on after tax income you will need to do this manually. You can run an earnings history report to get the gross earnings. You can run a deduction history report filtered for the appropriate deduction codes that affect your workers come. You may also need to run a benefit history report and add it any benefit codes that INCREASE taxable wages for workers comp. You will need to manually calculate the subject wages and amount of workers comp. This will need to be keyed into the workers comp tab of the Review/Modify Calculated payroll.
