hi,
calculation of employee and employer contribution is as below:
PF:-
Employee : - 12% of basic salary + DA (if you have in salary structure)
Employer:- 13.36% of Basic Salary + DA (if you have in salary structure) - 12% is PF Contribution & 1.36% is towards Admin Charges, EDLI & EDLI Admin charges.
ESI:-
Employee:- 1.75% of Gross Salary before deduction of PF,TDS etc.
Employer:- 4.75% of Gross Salary before deduction of PF,TDS etc.
TDS & PT:- as per the rules applicable.
hope i was able to clarify your doubts.
Warm Regards
Abhinav
