The issue of pensions became politically emotive in some recent Assembly elections. Some states, then run by non-National Democratic Alliance governments — such as Rajasthan, Chhattisgarh, and Punjab — reverted to the OPS, which will shift the pension burden to future generations. The Union government on its part formed a committee under then finance secretary T V Somanathan to look into the matter. Instead of “pay as you go” in the OPS, while the UPS will have a defined benefit, it will also have a defined contribution like the NPS. In the UPS, the employee will continue to contribute 10 per cent of the basic pay plus dearness allowance. The government on its part will now contribute 18.5 per cent instead of 14 per cent, which was stipulated in the NPS. The additional contribution would cost Rs 6,250 crore in the first year and another Rs 800 crore as a one-time expenditure on account of arrears. People who have taken voluntary retirement since the launch of the NPS will also be allowed to switch to the UPS. The scheme will be open to state government employees.
