Is NSC Interest Taxable? Yes — Taxed Yearly on Accrual

On accrual basis. Even though the interest is not physically paid each year and is automatically reinvested, you must declare the interest earned each year under 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 in that year.

NSC interest is added to your total income and taxed at your applicable income-tax slab rate — there is no special or concessional rate for it. So a person in the 30% bracket pays 30% plus 4% cess on the interest (after any 80C offset for years 1-4). It is not taxed at the 12.5% capital-gains rate; that applies only to equity long-term gains, not interest.

The NSC (VIII Issue) interest rate is 7.7% per annum, compounded annually. Small-savings rates including NSC and PPF were kept unchanged for the July–September 2025 (Q2 FY 2025-26) quarter. The rate applicable to your certificate is the one in force on the date you bought it, and it stays fixed for the full 5-year term.

No TDS is deducted on NSC interest. NSC is issued by India Post, which does not deduct any TDS on the interest — 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 accrued interest in your ITR each year as it remains taxable income.

Yes. "No TDS" does not mean tax-free. You must self-report the accrued NSC interest under Income from Other Sources every year. The accrued interest is increasingly reflected in your Annual Information Statement (AIS), so leaving it out can create a mismatch and trigger an income-tax notice.

Yes, for years 1 through 4. The interest earned on NSC is deemed to be reinvested in the same certificate, and this deemed reinvestment qualifies as a fresh 80C investment — so you can claim it (within the ₹1.5 lakh combined 80C limit) for years 1, 2, 3 and 4. The Year-5 interest is paid out at maturity, is not reinvested, and therefore gets no 80C deduction — it is fully taxable.

Yes. The amount you invest in NSC in the year of purchase qualifies for a Section 80C deduction, within the overall ₹1.5 lakh annual ceiling. Combined with the reinvested-interest benefit in years 1-4, NSC effectively gives two 80C claims — but both share the same ₹1.5 lakh limit and are available only under the old tax regime.

No. Section 80C deductions — including the NSC investment and the reinvested-interest deduction for years 1-4 — are available only under the old tax regime. If you have opted for the new regime, you get no 80C benefit, so all NSC interest is fully taxable each year with no offsetting deduction.

At maturity (end of Year 5) the principal plus accumulated interest is paid out. Years 1-4 interest has already been declared and taxed annually (and 80C was claimed on it). Only the Year-5 interest is freshly taxable in the maturity year — declared under Income from Other Sources with no 80C claim. The principal returned is not taxed again, as it came from post-tax or 80C-deducted money.

The principal portion of the maturity amount is not taxed again. The interest portion is taxable — but if you declared and taxed the interest annually on accrual (years 1-4), only the final Year-5 interest remains to be taxed in the maturity year. If you wrongly skipped the annual declarations, you may face a large one-time interest addition at maturity.

PPF is more tax-efficient on interest: PPF is EEE, so its interest is fully exempt under Section 10(11), while NSC interest is taxable. NSC pays a slightly higher rate (7.7% vs PPF 7.1%) and offers the reinvested-interest 80C benefit for years 1-4, but the interest is taxable. PPF has a 15-year lock-in versus NSC’s 5 years. For tax-free growth, PPF wins; for a shorter 5-year horizon with 80C, NSC is competitive.

They suit different risk profiles. NSC offers guaranteed ~7.7% returns, no market risk and a fixed 5-year tenure — good for conservative investors — but its interest is taxable. ELSS is an equity fund with a shorter 3-year lock-in and market-linked returns; its long-term gains above ₹1.25 lakh are taxed at 12.5% under Section 112A. For capital preservation and certainty NSC wins; for higher potential after-tax returns over a long horizon, ELSS typically outperforms.

Both interest streams are taxable, but a 5-year tax-saver FD suffers 10% TDS once interest crosses ₹40,000 a year (₹50,000 for seniors), whereas NSC has no TDS. NSC also gives the reinvested-interest 80C benefit in years 1-4, which a tax-saver FD does not. NSC currently pays a slightly higher rate. Both share the same 5-year lock-in and the ₹1.5 lakh 80C ceiling.

Report the accrued NSC interest each year under Schedule OS (Income from Other Sources) as interest income. For years 1-4, also show the same reinvested amount under Section 80C in Schedule VI-A (old regime). For year 5, report the interest in Schedule OS only, with no 80C entry. Use ITR-1 or ITR-2 depending on your total income and sources, and reconcile with your AIS before filing.

The frequent errors are: declaring all five years of interest only in the maturity year (it must be annual), claiming 80C on the Year-5 interest (not eligible), skipping the interest entirely because no TDS was deducted, and claiming NSC 80C deductions under the new tax regime where 80C does not apply. Any of these can cause an AIS mismatch or an income-tax notice.
