Dear Sanjay
The PF slip always shows the employee's contribution as 12% but employer's contributions will be shown as 3.67%. Please check the calculations based on your salary slip. The reason for doing this is that 8.33% employer's contribution goes to pension fund which is not shown in the calculations. You can confirm this fact from the covering letter that your company has received alongwith the PF slips from the PF Department. Dont worry, it is correct and normal practice of PF department.
