The National Pension System (NPS) [1] is a defined contribution based pension system launched by Government of India with effect from 1 January 2004. Like most other developing countries, India does not have a universal social security system to protect the elderly against economic deprivation. As a first step towards instituting pension reforms, Government of India moved from a defined benefit pension to a defined contribution based pension system. Apart from offering wide gamut of investment options to employees, this scheme would help government of India to reduce its pension liabilities. Unlike existing pension fund of Government of India that offered assured benefits, NPS has defined contribution and individuals can decide where to invest their money. The scheme is structured into two tiers:

Tier-I account: This NPS account does not allow premature withdrawal and is available from 1 May 2009

Tier-II account: The tier-II NPS account permits withdrawal.

Since 1 April 2008, the pension contributions of Central Government employees covered by the National Pension System (NPS) are being invested by professional Pension Fund Managers in line with investment guidelines of Government applicable to non-Government Provident Funds. A majority of State Governments have also shifted to the defined contribution based National Pension System from varying dates. 28 State/UT Governments have notified the NPS for their new employees. Of these, 5 states have already signed agreements with the intermediaries of the NPS architecture appointed by Pension Fund Regulatory and Development Authority (PFRDA) for carrying forward the implementation of the National Pension System. The other States are in the process of finalization of documentation.
