Mutual funds, on the other hand, are professionally managed schemes which invest in multiple investments. Both NPS and mutual funds are eligible for tax deductions under Section 80C of the IT Act, 1961. Both have a lock-in period; however, mutual funds have an advantage here. The lock-in period of ELSS funds is three years while NPS allows withdrawal only after the individual has attained 60 years of age or at the time of retirement. NPS has strict rules for premature withdrawals. A person can only withdraw 25 per cent of his corpus, and the limit to such withdrawals is 3 times during the scheme tenure. Mutual funds, on the other hand, do not have such restrictions. A person can withdraw the entire amount after the lock-in period of three years.
