How NSC works
National Savings Certificate (NSC) — currently the VIII Issue — is a government-backed fixed-income investment offered through India Post. It is specifically designed as a tax-saving, medium-term instrument with a 5-year lock-in.
Key mechanics:
- Minimum investment: ₹1,000 (in multiples of ₹100). No maximum limit.
- Term: 5 years (strictly — no premature closure except death/court order).
- Interest rate: 7.7% p.a. (Q1 FY 2026-27), compounded annually.
- Payout at maturity: Principal + all 5 years of compounded interest.
- 80C eligibility: Principal investment + reinvested interest (years 1–4) both qualify.
NSC maturity formula
NSC compounds annually for 5 years:
Maturity value = Principal × (1 + 7.7%)⁵
For ₹1,00,000 invested: ₹1,00,000 × (1.077)⁵ ≈ ₹1,44,903
Tax treatment — EET status
| Year | 80C deduction available | Taxable event |
|---|---|---|
| Year of investment | Yes (on principal) | None |
| Year 1 accrual | Yes (interest reinvested ≤ ₹1.5L cap) | None |
| Year 2 accrual | Yes (interest reinvested ≤ ₹1.5L cap) | None |
| Year 3 accrual | Yes (interest reinvested ≤ ₹1.5L cap) | None |
| Year 4 accrual | Yes (interest reinvested ≤ ₹1.5L cap) | None |
| Year 5 maturity | No | Full maturity value taxable at slab |
Important: The 80C benefit on reinvested interest is subject to the ₹1.5L aggregate cap. If your total 80C investments already exceed ₹1.5L, the reinvested NSC interest does not provide additional deduction.
NSC vs PPF
| Feature | NSC | PPF |
|---|---|---|
| Rate (Q1 FY 2026-27) | 7.7% | 7.1% |
| Compounding | Annual | Annual |
| Tax status | EET (interest taxable at maturity) | EEE (fully tax-free) |
| Term | 5 years (fixed) | 15 years (minimum) |
| Max deposit | No limit | ₹1.5L/yr |
| Premature closure | Not permitted (except death/court) | After 5 years (with penalty) |
| 80C on investment | Yes | Yes |
| 80C on accrued interest | Yes (notionally reinvested) | Not applicable (EEE) |
Key takeaway: NSC has a higher headline rate (7.7% vs 7.1%) but PPF is EEE — no tax on interest accrual or maturity. For investors in the 30% slab, the post-tax effective yield from NSC may be lower than PPF despite the higher gross rate. NSC is better for shorter investment horizons (5 years) and for investors who do not want a 15-year commitment.
NSC vs 5-year Post Office FD
| Feature | NSC | 5-yr Post Office FD |
|---|---|---|
| Rate | 7.7% p.a. (annual compounding) | 7.5% p.a. (quarterly compounding) |
| Effective yield | 7.7% | ~7.71% |
| 80C eligible | Yes | Yes |
| Premature closure | Not permitted | After 1 year (with penalty) |
| Interest treatment | Taxable at maturity (notionally reinvested 1–4) | Taxable annually or at maturity |
| Sovereign guarantee | Yes | Yes |
NSC’s annual compound rate (7.7%) vs Post Office FD’s quarterly compound rate (7.5% = ~7.71% EY) are very close. NSC has the advantage of 80C-eligible reinvested interest — an indirect tax shelter — while Post Office FD allows premature closure after 1 year with a penalty.
