The National Savings Certificate (NSC) is a five-year, fixed-rate investment sold at post offices and backed by the Government of India. You invest a lump sum from ₹1,000 upward, it earns a rate fixed for five years – around 7.7% this quarter – compounded yearly and paid at maturity, and the deposit qualifies for the Section 80C deduction. Its quirk is that the reinvested interest of the first four years also counts for 80C.
NSC is often bundled with PPF and tax-saving FDs as "an 80C option", but its tax mechanics are different from both, and understanding them is where the value hides.
NSC at a glance
How does the National Savings Certificate work?
You buy an NSC certificate for a lump sum at a post office, choosing any amount from ₹1,000 upward in multiples of ₹100. There is no maximum. The certificate carries a rate fixed at purchase, around 7.7% for the current quarter, and that rate stays with it for the full five years even if the government revises the small-savings rate later.
Interest compounds annually but is not paid out along the way. It is added to the certificate, and the entire amount – principal plus accumulated interest – is paid at the end of five years. So there is no monthly or yearly payout to rely on; NSC is a grow-and-collect instrument.
What makes NSC's tax treatment unusual?
This is the heart of NSC. The amount you invest qualifies for Section 80C, up to the shared ₹1.5 lakh cap, in the old regime. That much it shares with PPF and tax-saving FDs.
The twist is the interest. NSC interest is taxable, but because it is reinvested into the certificate rather than paid to you, it is treated as a fresh 80C investment in each of the first four years. So in years one to four, the interest is added back and also claimed under 80C, which cancels out the tax on it. Only the fifth and final year's interest is not reinvested, so it is taxable with no matching deduction.
| Year | Interest treatment | 80C on the interest? |
|---|---|---|
| 1 to 4 | Reinvested into the certificate | Yes, counts as fresh 80C |
| 5 (final) | Paid out at maturity | No |
The practical effect is that a large slice of NSC's interest escapes tax in the years it accrues, provided you have room left under the ₹1.5 lakh cap to absorb it.
Can you exit NSC early?
In the ordinary course, no. NSC has no premature encashment. It can be closed before five years only in narrow situations: the death of the holder, a court order, or forfeiture by a pledgee. This makes NSC less flexible than an RD or a bank FD, and it is a fixed commitment for the full term.
What it can do is serve as security. An NSC certificate can be pledged to a bank as collateral for a loan, then returned to you once the loan is settled.
NSC or a five-year tax-saving FD?
Both are five-year, 80C-eligible options often shelved side by side, and the choice between them is structural rather than a case of one being better. NSC carries a government-set rate fixed for the term, plus its reinvested-interest quirk on 80C. A five-year tax-saving bank FD carries a rate the bank sets, with interest that is taxable each year and, for most people under 60, not covered by any interest deduction. Both are locked for the full five years. Which one fits depends on the rate on offer, your remaining 80C headroom and how you want the interest handled, not on a single verdict.

NSC is a five-year commitment with a clever tax detail rather than a headline rate. Its reinvested-interest deduction rewards people who track their 80C cap closely, and quietly penalises those who assume every 80C option works the same way.
