Employer Contributions to Pension Fund
If your previous employer has contributed to the Pension Fund, your current employer should also continue contributing to the Pension Fund, even if your salary exceeds Rs 15,000. Whether to contribute on a salary higher than Rs 15,000 or not is a decision to be taken by the employer. Unless you had an agreement about it as part of your employment contract, the employer's act of contributing based on Rs 15,000 (which is Rs 1,800 per month) is unquestionable. However, when doing so, the employer should contribute Rs 1,250 to the Pension Fund and the remaining Rs 550 of their contribution to the Provident Fund, along with your contribution of Rs 1,800.
Checking Previous Contributions
Please check whether you informed the employer of your contribution to the Pension Fund in your previous company. Also, see if you provided Form 11 of EPF, declaring your existing PF account with a Universal Account Number and other details.
Post-September 2014 Joiners
If you joined after 1st September 2014, then you are not entitled to receive a pension. In such cases, if your previous employer contributed to the Pension Fund, that act should be void. In that scenario, the amount contributed to the Pension Fund will be redirected back to your Provident Fund.
