Is NSC interest taxable? Yes, every year, with a twist: interest of years one to four counts as reinvested in the certificate, and an old regime filer can deduct that deemed reinvestment in the very year it is taxed. In practice, for most holders, only the fifth year's interest ends up taxed.
Below: the deduction mechanics, the return entries, and the new regime difference. It explains rules; for your own return, check with a tax adviser.

Is NSC interest taxable? The short answer with numbers
You invest ₹1 lakh in NSC. Interest added: ₹7,700 in year 1, ₹8,293 in year 2, ₹8,931 in year 3, ₹9,620 in year 4 and ₹10,359 in year 5. You show each year's figure as income. In years 1 to 4, you also claim the same figure as a deduction, so it nets to zero, provided your ₹1.5 lakh limit has room. In year 5, the ₹10,359 is taxed at your slab.
The yearly figures come straight from the NSC calculator.
NSC tax benefit on the deposit
The amount you put into NSC counts toward the yearly deduction of up to ₹1.5 lakh. The new Income-tax Act moved it to section 123 with Schedule XV in place of 80C; the cap and the eligible list stayed. It applies only to individuals filing under the old regime.
That one ₹1.5 lakh ceiling also has to fit PPF, EPF, insurance premiums, home loan principal and school fees. If those already fill your limit, NSC adds no further deduction.
Is NSC tax free? Common myths
| Myth | Fact |
|---|---|
| NSC is tax free | The interest is taxable; only the deposit and reinvested interest are deductible |
| No tax because there is no TDS | No TDS does not mean no tax; you must declare it |
| Tax only at maturity | You can choose to declare yearly or at maturity, but yearly lets you use the deduction |
| The new regime gives the same benefit | No deduction in the new regime |
How to show NSC interest in income tax
- Work out each certificate's interest for the year using the rate on the certificate.
- Report it under income from other sources.
- Under the old regime, claim the same amount (for years 1 to 4) in the deduction section along with your other eligible savings.
- Keep the passbook or statement in case the department asks.
If you skipped yearly reporting, the whole interest is taxable in the maturity year. That can push you into a higher slab in one year, so yearly reporting is usually better.
New regime vs old regime for NSC holders
Under the new regime, neither the deposit nor the reinvested interest is deductible, and each year's interest is still taxable as it accrues, or at maturity. NSC then works like any other fixed return deposit. If you chose the new regime, compare NSC with a post office FD or KVP purely on return and lock in.
NSC compared with other tax savers
| Option | Lock in | Return taxed? |
|---|---|---|
| NSC | 5 years | Yes (mostly year 5) |
| PPF | 15 years | No, fully tax free |
| 5 year post office FD | 5 years | Yes, every year |
| SCSS (60+) | 5 years | Yes, every year |
PPF is the only fully tax free one. See the PPF guide.
