The National Pension System (NPS) is a voluntary, defined-contribution retirement savings scheme designed to enable systematic savings during working life.
The National Pension System (NPS) is a voluntary, defined-contribution retirement savings scheme created by the government to provide financial security and monthly income to individuals post-retirement. It enables working professionals to systematically accumulate a pension corpus throughout their career.
Contributions in NPS are professionally managed by pension fund managers across four asset classes: Equities (E), Corporate Bonds (C), Government Securities (G), and Alternative Assets (A). Investors can customize their asset split or choose an automated age-based allocation that dynamically reduces equity exposure as they approach retirement age.
Upon reaching age 60, up to 60% of the accumulated NPS corpus can be withdrawn completely tax-free as a lump sum. The remaining minimum 40% must be invested in a regulated annuity plan to ensure a guaranteed lifelong monthly pension stream. NPS also offers exclusive additional income tax deductions, making it a cornerstone for retirement planning.
