NSC Complete Guide 2026: National Savings Certificate Interest Rate, Lock-in, and Tax Rules
By Nitish Bharadwaj · Published Jul 21, 2026 · 7 min
The National Savings Certificate (NSC) is a post office scheme with a 5-year lock-in, currently earning 7.7% per annum compounded annually, paid at maturity. It qualifies for Section 80C deduction on the deposit amount. The interest earned each year is taxable, but the same interest is also deemed reinvested — which means it counts as a fresh 80C deduction for years 1 through 4. Only the fifth year's interest is taxable with no offsetting deduction. NSC suits investors who want guaranteed returns and have already used their PPF and ELSS limits.
The National Savings Certificate is one of the most overlooked instruments in the Indian small savings universe. It's government-backed, earns 7.7% per annum compounded annually, qualifies for Section 80C deduction, and has no upper investment limit — yet most investors default to PPF or ELSS without considering it. The reason is usually that its tax treatment is confusing. This guide explains exactly how NSC works, what the Section 80C and interest taxation looks like year by year, and when it actually makes sense.

How the Interest Compounds — A ₹1 Lakh Illustration
NSC interest is compounded annually but not paid out each year — it accumulates and is paid along with the principal at the end of 5 years. Here's what a ₹1 lakh investment at 7.7% looks like year by year:
| Year | Opening Balance | Interest (7.7%) | Closing Balance |
|---|---|---|---|
| Year 1 | ₹1,00,000 | ₹7,700 | ₹1,07,700 |
| Year 2 | ₹1,07,700 | ₹8,293 | ₹1,15,993 |
| Year 3 | ₹1,15,993 | ₹8,932 | ₹1,24,925 |
| Year 4 | ₹1,24,925 | ₹9,619 | ₹1,34,544 |
| Year 5 | ₹1,34,544 | ₹10,360 | ₹1,44,904 |
After 5 years, ₹1 lakh becomes ₹1,44,904 — a total interest of ₹44,904. No amount is paid during the 5-year period; everything comes at maturity.
Section 80C and Taxability — The Year-by-Year Picture
This is where NSC gets complicated — and where most guides get it wrong. There are two separate tax events: the 80C deduction on the deposit, and the annual taxability of the interest that accrues. Here's the complete picture:
| Year | What Is Deductible (80C) | What Is Taxable as Income |
|---|---|---|
| Year 1 | The original deposit (up to ₹1.5L 80C cap) | Year 1 interest — but deemed reinvested into NSC, so also 80C deductible* |
| Year 2 | Year 1 accrued interest (deemed reinvestment) | Year 2 interest — also 80C deductible as deemed reinvestment* |
| Year 3 | Year 2 accrued interest (deemed reinvestment) | Year 3 interest — also 80C deductible as deemed reinvestment* |
| Year 4 | Year 3 accrued interest (deemed reinvestment) | Year 4 interest — also 80C deductible as deemed reinvestment* |
| Year 5 | Year 4 accrued interest (deemed reinvestment) | Year 5 interest — TAXABLE, no 80C offset |
* The deemed reinvestment mechanism works like this: the interest that accrues each year is treated as if you reinvested it into a new NSC deposit. That reinvestment qualifies for 80C in the same year the interest accrues. So for years 1–4, the interest income and the 80C deduction cancel each other out — the net tax impact is zero. Only the Year 5 interest (₹10,360 on a ₹1 lakh investment) is truly taxable as income from other sources, with no offsetting deduction.
NSC vs Tax-Saving FD vs ELSS — Quick Comparison
| Feature | NSC | Tax-Saving FD | ELSS |
|---|---|---|---|
| Section 80C | Yes | Yes | Yes |
| Lock-in period | 5 years | 5 years | 3 years (shortest) |
| Returns | 7.7% (fixed) | 6.5–7.5% (fixed by bank) | Market-linked — 12–15% historical CAGR |
| Risk | Nil (sovereign guarantee) | Nil (up to ₹5L DICGC) | Market risk — can lose value |
| Interest / return taxability | Interest taxable (partially offset by 80C years 1–4) | Interest fully taxable each year | LTCG above ₹1.25L taxed at 12.5% |
| Upper limit | No limit | No specific limit (80C up to ₹1.5L) | No limit (80C up to ₹1.5L) |
| Premature withdrawal | Not allowed (except on death) | Not allowed (with penalty) | Not allowed |
How to Buy NSC in 2026
- Visit your nearest post office with PAN card, Aadhaar, and a passport-size photo for in-person purchase
- Online: log in to the DOP (India Post) net banking portal or the India Post Payments Bank (IPPB) mobile app — NSC can be purchased digitally and held in electronic (e-mode) form
- Select the investment amount (minimum ₹1,000; multiples of ₹100 thereafter)

- A physical certificate is issued for in-person purchases; electronic mode shows in your DOP savings account ledger
Who Should Invest in NSC
- Investors in the 10–20% tax bracket who want guaranteed, risk-free 80C investments and have maxed out their PPF contribution for the year
- Those who don't want the 3-year lock-in of ELSS and prefer a known return over market-linked outcomes
- Investors who have exhausted the ₹1.5 lakh PPF deposit limit and need another guaranteed-return 80C avenue
- Retirees or conservative investors who want sovereign-guaranteed fixed income with a moderate return (7.7%) — though senior citizens above 60 should first exhaust the SCSS limit at 8.2%
- NSC is less suitable for investors in the 30% tax bracket — at that rate, the taxable Year 5 interest is a meaningful cost, and better post-tax returns are often available from ELSS over any 5-year period
- It doesn't suit investors who might need the money before 5 years — premature exit is not allowed under any circumstances for living investors
Frequently Asked Questions
Is NSC interest taxable every year or only at maturity?
Technically, the accrued interest is taxable each year — but for years 1 through 4, it's simultaneously eligible for Section 80C as a deemed reinvestment, which cancels the tax. Only the Year 5 interest is taxable with no 80C offset. In practice, many investors declare it at maturity; declaring annually is the technically correct treatment.
What is the current NSC interest rate in 2026?
The NSC interest rate for Q1 FY 2026–27 (April–June 2026) is 7.7% per annum, compounded annually and paid at maturity. The rate is reviewed quarterly by the government and linked to G-Sec yields.
Can I take a loan against NSC?
Yes. NSC certificates can be pledged as collateral for bank loans. The certificate is transferred to the lender's name as security, and the loan amount is typically up to 85–90% of the face value. After the loan is repaid, the certificate is transferred back. This is useful if you need liquidity without breaking the instrument.
Is NSC better than PPF?
They serve different purposes. PPF has a 15-year lock-in (though with partial withdrawals after 7 years) and offers 7.1% tax-free returns — meaning no tax on interest at all. NSC offers 7.7% but the Year 5 interest is taxable. For investors in the 10–20% tax bracket and a 5-year horizon, NSC's higher rate and shorter lock-in can make it the better choice. For long-term wealth building with complete tax exemption on returns, PPF is superior despite the lower rate.
