Is NSC Interest Taxable? Complete Tax Guide 2026-27

Updated: 3 June 2026

Short answer: Yes — NSC (National Savings Certificate) interest is fully taxable. It accrues every year and must be declared as "Income from Other Sources" in your ITR annually, even though no cash is paid out. The good news: years 1–4 interest qualifies for Section 80C deduction (deemed reinvestment). No TDS is deducted by India Post.

NO TDS

NSC does not deduct TDS. You must self-report accrued interest in your ITR every year under "Income from Other Sources." Missing this is a common ITR error that can trigger an income-tax notice.

What Is NSC and How Does It Work?

National Savings Certificate (NSC) is a fixed-income savings scheme issued by India Post (Government of India). Key features for Tax Year 2026-27:

Tenure: 5 years (VIII Issue)
Interest rate: ~7.7% p.a. (compounded annually; revised quarterly by the government)
Interest payout: none during the 5-year period — interest is automatically reinvested each year
Maturity: lump-sum payout of principal + accumulated interest at end of Year 5
Available at: all post offices and select scheduled banks
Minimum investment: ₹1,000; no maximum

The "no payout" structure means many investors mistakenly assume they don't need to report interest until maturity. That is incorrect — the Income-tax Act 2025 taxes interest on an accrual basis.

Year-by-Year NSC Tax Treatment (₹1 Lakh Investment)

Below illustrates approximate interest accrual on a ₹1,00,000 NSC at 7.7% p.a. — actual figures depend on the rate at time of purchase.

Year	Interest Earned (approx.)	Taxable as Income?	80C Deduction Available?	Net Tax Impact
Year 1	₹7,700	Yes — "Other Sources"	Yes (deemed reinvestment)	Can offset with 80C claim
Year 2	₹8,293	Yes — "Other Sources"	Yes (deemed reinvestment)	Can offset with 80C claim
Year 3	₹8,932	Yes — "Other Sources"	Yes (deemed reinvestment)	Can offset with 80C claim
Year 4	₹9,620	Yes — "Other Sources"	Yes (deemed reinvestment)	Can offset with 80C claim
Year 5 (maturity)	₹10,361	Yes — "Other Sources"	No — paid out, not reinvested	Fully taxable, no deduction

Note: Interest figures are illustrative at 7.7% compounding. Actual interest depends on the rate applicable at the time your NSC was purchased.

Section 80C and NSC — Two Ways to Claim

NSC gives you two separate 80C benefits — both count within the overall ₹1.5 lakh annual 80C limit (old tax regime only):

Benefit	What Qualifies	When to Claim
Initial investment	The lump sum you invest in NSC	Year of purchase
Reinvested interest (Years 1–4)	Interest accrued and auto-reinvested	Each year (Years 1 to 4)
Year 5 interest	Not reinvested — paid at maturity	Taxable only; no 80C deduction

Practically, if you are in the 30% tax bracket and the NSC interest is both taxable income and an 80C deduction in the same year (years 1–4), the net tax effect on that year's interest is zero — provided you haven't already exhausted your ₹1.5L 80C limit with other investments.

NSC vs FD vs PPF — Tax Comparison

Feature	NSC	Fixed Deposit (5yr Tax Saver)	PPF
Interest rate (approx.)	7.7% p.a.	6.5–7.25% p.a.	7.1% p.a.
Interest taxability	Taxable (accrual basis)	Taxable (accrual or receipt)	Fully exempt
TDS deducted	No	Yes — 10% if interest >₹40K/yr	No
80C on investment	Yes (up to ₹1.5L)	Yes (up to ₹1.5L)	Yes (up to ₹1.5L)
80C on interest	Yes (years 1–4)	No	N/A (exempt)
Lock-in	5 years	5 years	15 years
Premature withdrawal	Not allowed (except death/court)	Allowed with penalty	Partial after 7 years
Best for	Tax saving + moderate return	Flexibility + TDS visibility	Long-term tax-free growth

How to Report NSC Interest in ITR

In your ITR, NSC interest is reported under Schedule OS (Income from Other Sources):

Add the accrued interest amount each year under "Interest from NSC"
In Schedule VI-A (Deductions), show the same amount (years 1–4) under Section 80C as "NSC reinvested interest"
Year 5: show maturity year interest in Schedule OS only — no 80C entry
ITR forms: ITR-1 or ITR-2 depending on your total income and source of income

Many bank CBS systems and AIS (Annual Information Statement) now auto-populate NSC interest data from India Post — cross-check your AIS before filing.

Common Mistakes to Avoid

Declaring all 5 years' interest only in the maturity year — incorrect; must be declared annually
Claiming 80C deduction on Year 5 interest — not eligible
Forgetting to declare NSC interest in ITR because "no TDS was deducted"
Claiming NSC benefits under the new tax regime — 80C deductions are only available under the old regime

Frequently Asked Questions

Is NSC interest taxed on accrual basis or receipt basis?

NSC interest is taxed on an accrual basis, not on receipt. Even though the interest is not physically paid out each year — it is automatically reinvested — you are still required to declare the interest earned each year as "Income from Other Sources" in your ITR. You cannot defer the tax to maturity and declare five years of interest in one go. Each year's accrued interest must be shown for that Tax Year.

Is there TDS on NSC interest? Can senior citizens avoid it?

No TDS is deducted on NSC (National Savings Certificate) interest. NSC is issued by India Post and the post office does not deduct any TDS on the interest earned. This applies to all investors — including senior citizens — so there is no need to submit Form 15G or 15H for NSC. However, you must still self-declare the interest in your ITR each year, as it is taxable income under "Income from Other Sources".

Can I claim 80C deduction on NSC reinvested interest?

Yes, for years 1 through 4. The interest earned on NSC is deemed to be reinvested in the same NSC. This deemed reinvestment qualifies as a fresh investment for Section 80C purposes — so you can claim up to the applicable 80C limit (₹1.5 lakh combined) for the interest reinvested in years 1, 2, 3, and 4. However, the Year 5 interest (maturity year) is not reinvested and therefore does not qualify for any 80C deduction — it is fully taxable without an offsetting deduction.

NSC vs ELSS — which is better for 80C?

They serve different risk profiles. NSC offers guaranteed returns (~7.7% p.a.), no market risk, and a fixed 5-year tenure — ideal for conservative investors. ELSS (Equity Linked Savings Scheme) has a shorter lock-in of 3 years and market-linked returns (historically 10-14% over long periods) but carries equity risk. A key difference: NSC interest is taxable; ELSS long-term capital gains above ₹1.25 lakh are taxed at 12.5%. If capital preservation and certainty matter more than growth, NSC wins. For higher after-tax returns over a 10-year horizon, ELSS typically outperforms.

What happens to NSC tax at maturity?

At maturity (end of Year 5), the entire principal plus accumulated interest is paid out. For tax purposes, years 1–4 interest has already been declared and taxed annually (and 80C deductions were claimed). Only the Year 5 interest is freshly taxable in the maturity year — you declare it under "Income from Other Sources" and cannot claim 80C on it since it is not reinvested. The principal returned is not taxed again (it was invested from post-tax or 80C-deducted money).
