Dear Nagesh,
The matter in query is interpreted rightly by both Mr. Abbas and Mr. Madhu. The choice is yours, as both employee and employer, whether to choose to contribute or not, as the matter has become optional.
However, you mentioned the age of the employee being 60. Therefore, prior to 2 years, what was the position of contribution? Because after 58, pension contributions have to be stopped mandatorily.
Please check this point and proceed with a remedy.
Regards,
KIRAN KALE
