How it works
National Savings Certificate (VIII Issue) is a sovereign small savings instrument backed by the Government of India with a fixed tenure of 5 years.
Interest is compounded annually at the notified sovereign rate (currently 7.70% p.a.) and paid out as a lump sum along with the principal at maturity.
Section 80C Tax Deduction: The initial deposit qualifies for deduction under Section 80C up to ₹1,50,000.
Deemed Reinvestment Rule: Interest accrued at the end of years 1, 2, 3, and 4 is legally deemed to be reinvested into NSC and also qualifies for a fresh Section 80C deduction in those respective financial years. Only the year 5 interest is fully taxable.
Formula
Maturity Value = Principal x (1 + r/100)^5; Total Interest = Maturity Value - Principal
- Principal
- = Invested certificate amount (minimum ₹1,000)
- r
- = Annual interest rate notified by Ministry of Finance (7.70% p.a.)
- 5
- = Fixed statutory tenure of 5 years
No Tax Deducted at Source (TDS) is subtracted by the Post Office at maturity.
