NSC
National Savings Certificate (NSC) is a 5-year fixed-income post office savings scheme guaranteed by the Government of India, offering a fixed interest rate (revised quarterly) with maturity proceeds and accrued interest qualifying for Section 80C tax benefit.
Understanding NSC
NSC is one of the safest fixed-income instruments in India — sovereign-guaranteed, fixed-rate (locked at issuance), with no credit or interest-rate risk during the 5-year term. Available at any post office; cannot be bought online directly (some banks offer NSC purchases through their branches).
The interesting tax feature: interest accrued in years 1–4 is reinvested in the certificate and qualifies for fresh 80C deduction in those years. Effectively, you can keep the same NSC investment qualifying for 80C through reinvestment of interest — though the final-year interest is paid out and doesn't reinvest.
Why it matters
NSC's combination of safety, fixed-rate, and tax-stacking makes it attractive for conservative investors who want predictable returns and a tax shelter. The 5-year lock-in is shorter than PPF's 15 years; the rate is competitive with bank tax-saver FDs but with sovereign guarantee. Particularly suited for senior citizens and risk-averse savers.
Example
An old-regime taxpayer invests ₹1 lakh in NSC. Annual interest accrual at 7.7%: Year 1 ≈ ₹7,700; Year 2 ≈ ₹8,293 (on ₹1,07,700); Year 3 ≈ ₹8,931, etc. At maturity (Year 5), they receive ₹1,44,920. The accrued interest in years 1–4 (~₹26,924 total) can be claimed as fresh 80C deduction in those years — a useful tax-stacking opportunity.
