Ptax Calculation Issue

Dear Experts,

I have an issue pertaining to the Ptax Calculation. We have run the Payroll for April & May 2012 and the Ptax for these months has been deducted properly i.e. Rs. 175/- (Maharashtra State).

But for the month of June the Ptax is being deducted as Rs. 200/- which is incorrect.

Below are the details:

Earnings

Basic Pay : 7500

HRA : 1943

Conveyance : 188

Medical : 250

Total : 9881

Deductions

Ee PF Contri : 900

Ee ESI Contri : 173

Ee LWF : 12

PTax - Split Period: 200

Salary Advance: 1500(-)

Total: 2785

/101 Wage Type Amount : 9881

/3PS Amount : 10381

Can you please advise if there is some issues with the Processing or Cumulations Class

Thanks,

Ayubi
