The National Pension System (NPS) is a voluntary, long-term retirement savings scheme designed to enable systematic savings. Upon maturity at age 60, a portion of the corpus is paid as a lump sum, and the remaining must be invested in an annuity to provide a regular monthly pension.
No, you can withdraw up to 60% of the corpus as a tax-free lump sum. The remaining 40% must be used to purchase an annuity to receive a monthly pension.
NPS offers an additional deduction of up to INR 50,000 under Section 80CCD(1B), over and above the INR 1.5 Lakh limit of Section 80C.
