The Old Pension Scheme and the NPS: The Debate

No question in Indian pension policy has been more contested than the choice between the Old Pension Scheme (OPS) and the National Pension System (NPS). The shift from one to the other in 2004 was among the most significant fiscal reforms of its time; the demand to reverse it became a major political issue from 2022, and led to the Unified Pension Scheme in 2025. Understanding the debate requires understanding how the two systems differ in law, in economics and in who bears the risk.

1. The Old Pension Scheme

• Defined benefit: a pension of 50 per cent of the last pay drawn (or of average emoluments, whichever was more beneficial) after qualifying service, under the CCS (Pension) Rules.
• Non-contributory: employees did not contribute to the pension, though they contributed to the General Provident Fund, a separate savings scheme.
• Unfunded: pensions were paid from current revenues of the Government, not from an accumulated fund.
• Inflation-protected: pensions rose with dearness relief and were revised with pay commissions.
• Family pension: continued to the spouse and eligible dependants.

2. Why the NPS Replaced It

• Fiscal burden: pension spending was growing faster than revenues, as life expectancy rose and pay commissions raised pensions.
• Intergenerational fairness: unfunded pensions shift the cost of today's services to future taxpayers.
• Coverage: the OPS covered only Government employees, a small fraction of the workforce. A funded, portable system could be extended to everyone.
• Capital formation: a funded system builds long-term savings that can finance infrastructure and development.
• Reform path: the change followed the OASIS report (2000) and later expert advice, was notified on 22 December 2003 for recruits from 1 January 2004, and was given statutory basis by the PFRDA Act, 2013.

3. The Case for Returning to the OPS

• Income certainty: NPS pensions depend on markets and annuity rates, and many early retirees received pensions far below what the OPS would have paid.
• Inflation risk: a level annuity loses value over time; the OPS was indexed.
• Employee contribution: NPS employees pay 10 per cent of pay, while OPS employees paid nothing towards the pension.
• Equity among employees: employees doing the same work receive very different retirement benefits depending on when they joined.
• Short-term fiscal relief: a State that stops NPS contributions saves money immediately, because OPS pensions for new recruits fall due only decades later.

4. The Case against Reversion

• Long-term cost: an RBI staff paper published in the RBI Bulletin in September 2023 estimated that if all States reverted, the cumulative fiscal burden could be up to 4.5 times that of the NPS, with additional annual pension spending reaching about 0.9 per cent of GDP by 2060. The RBI noted that the views were those of the authors.
• Deferred liability: the short-term savings come at the cost of large unfunded liabilities for future Governments, crowding out spending on development.
• Equity with the wider population: most citizens have no assured pension at all; a generous, tax-funded pension for Government employees is paid for partly by them.
• Legal complications: accumulated NPS corpus cannot simply be returned to States.

5. The Political and Legal Course of the Debate

• Reversions: from 2022, Rajasthan, Chhattisgarh, Jharkhand, Punjab and Himachal Pradesh announced a return to the OPS for their employees and informed PFRDA.
• Central position: the Central Government has repeatedly stated in Parliament that it has no plan to restore the OPS for its employees, most recently in December 2025.
• One-time option for some employees: by an Office Memorandum of 3 March 2023, Central Government employees appointed against posts advertised or notified before 22 December 2003, but who joined on or after 1 January 2004, were given a one-time option to move to the OPS.
• Review committee: in 2023, a committee chaired by T.V. Somanathan was set up to review the NPS for Government employees. Its work led to the Unified Pension Scheme, effective 1 April 2025.

6. The UPS as a Middle Path

The UPS keeps the contributory, funded structure of the NPS, with the employee paying 10 per cent and the Government 18.5 per cent, but promises an assured payout of 50 per cent of average basic pay of the last year for 25 years' service, a minimum of ₹10,000, family payout and dearness relief. It thus answers the demands for certainty and indexation while avoiding a return to an unfunded system. Critics on one side say it is less generous than the OPS; critics on the other say it reintroduces an open-ended fiscal guarantee.

7. Comparison at a Glance

• Nature: OPS defined benefit; NPS defined contribution; UPS assured payout on a contributory base.
• Funding: OPS unfunded; NPS and UPS funded.
• Employee contribution: OPS none to pension; NPS and UPS 10%.
• Risk-bearer: OPS the Government; NPS the employee; UPS largely the Government.
• Indexation: OPS yes; NPS no, unless an increasing annuity is bought; UPS yes.
• Legal basis: OPS CCS (Pension) Rules; NPS PFRDA Act and CCS (Implementation of NPS) Rules, 2021; UPS 2025 Rules within the NPS.
