Hi, Deepika.
The present upper limit for PF is Rs. 6,500. So, the 12 percent of Rs. 6,500 is Rs. 780. The employee pays Rs. 780, and the employer also puts in Rs. 780. Out of the contribution paid by the employer (out of Rs. 780), Rs. 541 goes to EPS, which is the pension scheme, and Rs. 239 goes to the individual's PF account.
Now, if your basic plus DA is more than Rs. 6,500, you cannot be forced to join EPF. Furthermore, you can increase your contribution, which means you can contribute more than 12 percent of your basic and DA, but the employer need not match that. It is up to the employer. If the employer matches the increased contribution, that amount minus Rs. 541 goes into your PF account.
Whereas your company has opted for a full 8.33 percent contribution to EPS, out of the contribution given by the employer, the full 8.33 percent will be credited to the EPS. For example, if your basic plus DA is Rs. 10,000, your contribution is Rs. 1,200 and the employer's contribution is Rs. 1,200. Out of the employer's Rs. 1,200, an amount of Rs. 833 will be credited to the EPS account, and the rest to your PF account.
In this case, when you retire, your average salary of the last 10 months will be taken into account for calculating your PF pension. Whereas, where the limit is Rs. 6,500, your last salary is considered only Rs. 6,500, even if your total salary when you retire is Rs. 100,000.
