Is NSC Interest Taxable?
Yes — Taxed Yearly on Accrual
How National Savings Certificate interest is taxed — the accrual rule, the ₹1.25 lakh myth, the Section 80C deduction on reinvested interest for years 1-4, why there is no TDS, and where to report it in your ITR.
Yes — NSC interest is fully taxable. National Savings Certificate interest is taxed under "Income from Other Sources" on an accrual basis every year, even though no cash is paid out (the interest is auto-reinvested). The interest that is reinvested in years 1 to 4 qualifies for a Section 80C deduction, so in those years the interest can be tax-neutral if you have 80C headroom. Year-5 interest is fully taxable with no 80C offset. India Post deducts no TDS — you must self-declare it. There is no ₹1.25 lakh exemption (that is for equity LTCG, not interest).
Why NSC Interest Is Taxed Every Year
NSC pays no interest during its 5-year term — the interest compounds and is paid as a lump sum at maturity. But the Income-tax Act taxes this interest on an accrual basis: the interest that accrues each year is your income for that year, taxed at your slab rate. You cannot defer all five years of interest to the maturity year. This is the single most common NSC mistake and a frequent trigger for an Income from Other Sources mismatch notice.
| Parameter | Position |
|---|---|
| Head of income | Income from Other Sources |
| Tax basis | Accrual — declared each year |
| Tax rate | At your applicable slab rate (no special rate) |
| TDS by India Post | None — no Form 15G/15H needed |
| 80C on investment | Yes — within ₹1.5L (old regime only) |
| 80C on reinvested interest | Yes, years 1-4 — deemed reinvestment |
| 80C on year-5 interest | No — paid out at maturity, not reinvested |
| Principal at maturity | Not taxed again (already taxed / invested from post-tax money) |
NSC (VIII Issue) current rate 7.7% p.a., compounded annually — unchanged for the Jul–Sep 2025 (Q2 FY26) quarter. Rate applicable is the one in force when the certificate was bought.
Because India Post deducts no TDS, many investors wrongly assume NSC interest is exempt or that nothing needs reporting. It is fully taxable — and since the accrued interest now appears in your AIS, skipping it in your return is a common cause of a mismatch notice. Report the accrued interest for each year even though you receive no cash.
Year-by-Year NSC Tax on a ₹1 Lakh Certificate
Approximate interest accrual on a ₹1,00,000 NSC at 7.7% p.a. compounded annually. Each year’s interest is taxable in that year; years 1-4 interest is also deductible under 80C (deemed reinvestment), year-5 interest is not.
| Year | Interest accrued | Taxable? | 80C on interest? | Net effect |
|---|---|---|---|---|
| Year 1 | ₹7,700 | Yes | Yes | Can be neutral with 80C |
| Year 2 | ₹8,293 | Yes | Yes | Can be neutral with 80C |
| Year 3 | ₹8,932 | Yes | Yes | Can be neutral with 80C |
| Year 4 | ₹9,620 | Yes | Yes | Can be neutral with 80C |
| Year 5 (maturity) | ₹10,361 | Yes | No | Fully taxed at slab |

Year 1-4 interest with 80C headroom
Year 5 interest, 30% slab
The “tax-neutral” benefit on years 1-4 only works if you still have room within the ₹1.5 lakh Section 80C ceiling. If you already max out 80C with EPF, PPF, ELSS or home-loan principal, the reinvested NSC interest becomes plain taxable income. And under the new tax regime, 80C is not available at all — so all NSC interest is taxable with no offset.
Section 80C on NSC — Investment and Reinvested Interest
NSC gives you two distinct 80C claims, both counting within the single ₹1.5 lakh annual ceiling (old regime only):
- The initial investment — the amount you put into NSC is deductible u/s 80C in the year of purchase.
- Reinvested interest (years 1-4) — interest that accrues and is deemed reinvested counts as a fresh 80C investment each year.
- Year-5 interest is not reinvested — it is paid out at maturity, so it gets no 80C deduction and is fully taxable.
- Both claims share the same ₹1.5 lakh 80C limit — they do not stack above it.
NSC vs PPF vs 5-Year Tax-Saver FD
| Feature | NSC | PPF | 5-yr Tax-Saver FD |
|---|---|---|---|
| Interest rate (approx.) | 7.7% | 7.1% | 6.5-7.25% |
| Interest taxability | Taxable (accrual) | Fully exempt (EEE) | Taxable |
| TDS | None | None | Yes — 10% over ₹40K/₹50K |
| 80C on investment | Yes (₹1.5L) | Yes (₹1.5L) | Yes (₹1.5L) |
| 80C on interest | Yes (yr 1-4) | N/A (exempt) | No |
| Lock-in | 5 years | 15 years | 5 years |
PPF interest is exempt u/s 10(11); NSC interest is taxable. Both 80C benefits apply under the old regime only. FD TDS threshold ₹50,000 for senior citizens.

Have NSC, PPF, FD and ELSS to slot into 80C and your ITR correctly? Get it filed by a CA.
File ITR with a CA →How to Report NSC Interest in the ITR
- Add each year’s accrued NSC interest under Schedule OS — “Interest from NSC / Other Sources”.
- For years 1-4, show the same reinvested interest under Section 80C in Schedule VI-A (old regime).
- For year 5, report the interest in Schedule OS only — no 80C entry.
- Cross-check the accrued interest against your AIS / Form 26AS before filing.
- Choose ITR-1 or ITR-2 based on your total income and other sources.
NSC works well if
- You want guaranteed, government-backed returns
- You still have 80C headroom for years 1-4
- You are in the old tax regime
- You want no equity/market risk
Reconsider if
- You are in the new regime (no 80C benefit)
- Your 80C ₹1.5L is already exhausted
- You want tax-free interest — PPF is better (EEE)
- You may need early liquidity — NSC has no premature exit
(1) Declaring all five years of interest only at maturity — it must be annual. (2) Claiming 80C on year-5 interest — not eligible. (3) Skipping the interest because “no TDS was deducted”. (4) Claiming any NSC 80C deduction under the new regime, where 80C does not apply.
