The National Pension System (NPS) is a government-sponsored retirement savings scheme in India. It aims to provide financial security to individuals after they retire. Under this system, individuals can contribute regularly during their working years, and the accumulated funds are invested in various financial instruments to grow over time. NPS is open to all citizens, including self-employed individuals and government employees. It offers tax benefits on contributions and allows for flexible investment choices. Upon retirement, subscribers can withdraw a portion of their savings as a lump sum and must use the remaining amount to purchase an annuity for regular income.
