The pension sector regulator has said all eligible government employees (central & state) on the rolls of the government can be enrolled into the National Pension System (NPS), irrespective of age at the time of entry.
However, this is subject to the condition that the total period of contribution to NPS account shall not be more than 42 years. NPS is the contributory pension scheme launched by the Union government in January 2004. It was made compulsory for all new government employees.
