Understanding PF Deductions
It appears that you are confused about the PF deduction.
Firstly, the total contribution to the Provident Fund is 24%, plus administrative charges borne by the employer. In that 24%, the employer's contribution is 12% plus admin charges, and the employee's contribution is 12%.
Secondly, this 12% is calculated on the basic salary amount.
Types of PF Contributions
There are mainly two kinds of PF contributions: 1) Limited PF and 2) Unlimited PF.
Limited PF, as discussed above, has a maximum limit of Rs. 6500/-. Limited companies that want to contribute a fixed amount of PF irrespective of the salary drawn by the employees would opt for the limited PF.
For example, if the employee's basic salary is Rs. 4500/- per month, the employer shall pay 12% of Rs. 4500/-. In case the employee's basic pay is Rs. 7500/-, then the employer pays 12% only for Rs. 6500/-, even if the employee's basic exceeds it.
Unlimited PF is where the company opts to pay 12% on whatever basic salary is drawn by the employees.
This whole concept of Limited and Unlimited PF is called the "PF Ceiling Effect."
Exemption from PF
There is also a situation where the employer is exempted from PF. This does not mean that the employer does not need to pay the PF amount, but they will not take the PF code from any of the PF authorities to pay the amount. Do not be surprised. These companies will have their own PF Offices at their companies, with the reason being the major turnover and transactions of the company. (Such PF authority at the company will be controlled by the government itself.)
From the 12% of the PF payment, 8.33% will go to the pension fund.
So, there should not be any confusion regarding the PF payment and the kinds of PF/Ceiling of PF. It is like PF is the tree and the Ceiling of PF is the branch.
