National Pension System (NPS) is a retirement benefit Scheme introduced by the Government of India to facilitate a regular income post retirement to all the subscribers. PFRDA (Pension Fund Regulatory and Development Authority) is the governing body for NPS. This scheme allows subscribers to contribute regularly in a pension account during their working life. On retirement, subscribers can withdraw a part of the corpus in a lumpsum and use the remaining corpus to buy an annuity to secure a regular income after retirement.
