Post Office NSC 2026: Interest Rate & Tax Benefits

The National Savings Certificate (NSC) is a five-year, government-backed savings certificate sold at post offices that combines a fixed return with a tax deduction. It currently pays 7.7% a year, compounded annually, and qualifies for a Section 80C deduction, which makes it one of the most popular tax-saving instruments in India.

Because it is a Government of India small-savings scheme, the principal and interest are effectively guaranteed, so the NSC appeals to conservative savers who want a fixed, predictable outcome alongside a tax break. The saver buys a certificate for a lump sum and receives the full amount with interest after five years.

This guide explains how the NSC works in 2026: the current interest rate, how much a deposit grows to, the investment limits, the Section 80C tax benefit and how the reinvested interest is treated, the rules on withdrawal and pledging, and how to buy one.

What is the National Savings Certificate?

The NSC is a fixed-income certificate with a 5-year term, bought with a one-time lump sum. India Post issues the certificate, and the saver receives the principal plus accumulated interest at maturity, with the rate fixed for the whole term on the purchase date.

It is designed as a save-and-grow instrument rather than an income product: the interest is not paid out yearly but accrues and compounds, then is paid in full at the end. This makes it suitable for savers with a lump sum who want guaranteed growth and a tax deduction in the year of purchase.

As a sovereign-backed scheme available at every one of India Post's 154,000-plus branches, the NSC is one of the most widely accessible tax-saving options in the country, especially outside the big cities.

The certificate is now issued in electronic (e-mode) form rather than the printed paper certificates of the past, held within the saver's post office account. This makes it easier to track, transfer, and redeem at maturity, while keeping the same underlying rules.

NSC interest rate in 2026

The NSC interest rate is 7.7% per annum for the first quarter of FY 2026-27 (April-June 2026), compounded annually but paid at maturity. The rate is set by the Ministry of Finance and reviewed quarterly, and it was carried over unchanged from the previous quarter.

"The rates of interest on various small savings schemes for the first quarter of FY 2026-27 remain unchanged from those notified for the fourth quarter of FY 2025-26." (Ministry of Finance small-savings rate notification, 2026, as reported by ClearTax.)

Crucially, the NSC fixes its rate at the time of purchase, so a certificate bought today earns 7.7% for the full five years regardless of any later quarterly revisions. This rate certainty is one of the NSC's main attractions over floating-rate options.

NSC returns: how much it grows

At 7.7% compounded annually, an NSC roughly multiplies the investment by 1.449 over five years, so ₹1,00,000 grows to about ₹1,44,900. The table below shows approximate maturity values for common amounts.

Maturity values are approximate and depend on the exact rate at purchase; the certificate's value is fixed once bought. Because the interest compounds annually and is paid only at the end, the NSC behaves like a five-year cumulative deposit.

The compounding is what separates the NSC from a simple-interest product. At 7.7% simple interest, ₹1 lakh would earn ₹38,500 over five years; the annual compounding lifts that to about ₹44,900, roughly ₹6,400 more, purely from interest earning interest.

That fixed, knowable maturity value also makes the NSC easy to plan around. A saver can buy a certificate sized so it matures to a specific target - a tuition payment or an insurance renewal due in five years - with complete certainty about the amount that will be available.

Deposits, limits, and eligibility

The NSC has a low entry point and no upper limit: the minimum is ₹1,000, with further purchases in multiples of ₹100, and there is no maximum amount that can be invested. The 80C deduction, however, is capped regardless of how much is bought.

Any resident Indian adult can buy an NSC, individually or jointly, and a guardian can buy one on behalf of a minor. A minor aged 10 or above can hold a certificate in their own name within the rules.

Because there is no cap on the amount, savers often use the NSC for sums beyond the ₹1.5 lakh 80C limit too, simply for the guaranteed return, accepting that the excess does not get the deduction.

The certificate can also be transferred from one person to another and from one post office to another under defined conditions, which adds flexibility for gifting or relocation. A common use is buying NSCs in the name of a spouse or major child to organise family savings, within the applicable tax rules.

NSC tax benefits and how interest is treated

The amount invested in an NSC qualifies for a deduction of up to ₹1.5 lakh a year under Section 80C, the same overall limit shared with PPF, the 5-year TD, and life insurance. This is the headline reason most savers buy it.

The interest works in a useful way: because it is reinvested each year rather than paid out, the interest for the first four years is itself treated as a fresh 80C-eligible investment, effectively giving an additional deduction. Only the final year's interest is not reinvested and is fully taxable.

The total interest is taxable as income, but the annual reinvestment relief softens the impact for many savers. Because tax outcomes depend on the individual's total income and tax regime, the actual benefit varies, and this is general information rather than tax advice.

One point often missed is that the 80C deduction on both the original investment and the reinvested interest is available only under the old tax regime. Savers who have opted for the new regime get the NSC's guaranteed return but not the deduction, so the regime choice should be settled before counting on the tax benefit.

Premature withdrawal and pledging

The NSC has a strict 5-year lock-in and cannot generally be encashed early. Premature closure is permitted only in limited cases: the death of the holder, a court order, or forfeiture by a pledgee who is a government body.

The certificate can, however, be pledged as security for a loan from banks and other approved lenders, which provides liquidity without breaking the investment. This makes the NSC more flexible than its lock-in alone suggests, since the holder can borrow against it in an emergency.

Because early exit is so restricted, the NSC should be treated as a genuine five-year commitment. Savers who may need the money sooner are usually better served by a shorter Time Deposit.

The pledging route is the practical workaround for liquidity. Rather than trying to break a certificate early, a holder facing a cash need can pledge it to a lender and borrow against its value, keeping the NSC intact so it still matures at the guaranteed amount with the tax benefit preserved.

NSC compared with PPF and the 5-year FD

Among 80C options, the NSC sits between the PPF and the 5-year Time Deposit. It pays 7.7%, higher than PPF's 7.1% and the TD's 7.5%, but its interest is taxable, whereas PPF is entirely tax-free.

The choice depends on horizon and tax position: PPF suits very long-term, tax-free goals with a 15-year lock-in, the 5-year TD and NSC suit medium-term tax-saving, and the NSC's annual reinvestment relief can make its effective tax hit lighter than a plain taxable deposit. Many savers hold more than one to balance return, liquidity, and tax, as compared in IndiaPost's guide to NSC vs PPF vs FD.

A practical edge of the NSC over the 5-year bank tax-saver FD is the reinvestment relief on interest, which a bank FD does not offer. Against PPF, the NSC wins on horizon flexibility - five years versus fifteen - making it the natural 80C choice for savers who want the deduction without locking money away for a decade and a half.

Who the NSC suits best

The NSC fits a saver with a lump sum and a five-year horizon who wants a guaranteed return plus a Section 80C deduction, particularly one on the old tax regime. It is a natural choice for a salaried taxpayer anchoring part of their 80C limit in a safe instrument rather than a market-linked one.

It suits less well a saver who may need the money within five years, given the strict lock-in, or one on the new tax regime who would forgo the deduction. For those, a shorter Time Deposit or a tax-free option like PPF may serve better, depending on the goal.

NSC in a family savings plan

Because there is no upper limit and certificates can be held jointly or in a spouse's or major child's name, the NSC is often used to organise family savings within the tax rules. A household can buy certificates sized to specific future needs, each maturing to a known amount.

Used alongside PPF for the long term and an RD for monthly saving, the NSC fills the medium-term, tax-saving slot in a family's plan. Its certainty of outcome makes it easy to earmark for a dated goal a few years away.

How to buy an NSC

Buying an NSC takes one visit to any post office with three standard documents: a completed application form, KYC proof (Aadhaar and PAN), and a passport-size photograph. Payment is made by cash or cheque, and the certificate is issued in electronic form in the saver's account.

An existing Post Office Savings Account makes the process smoother, and India Post Payments Bank is gradually enabling more digital access, as set out in IndiaPost's guide to how to open a Post Office savings scheme. Nominating a beneficiary at purchase is advisable, as it simplifies matters for the family.

The best time to buy for tax purposes is before the financial year ends, since the deduction applies to the year of investment. Many savers buy in the January-to-March window to claim the deduction, though buying earlier in the year starts the interest clock sooner and is generally the better financial choice.

"The National Savings Certificate is a five-year scheme that can be purchased at any departmental post office, with interest compounded annually and payable at maturity." (India Post, Banking Services.)

Why the NSC remains a tax-season favourite

The NSC's enduring popularity comes from a simple combination: a guaranteed return higher than many bank deposits, a Section 80C deduction, and the reach of the post office network. For a saver who wants to use part of their 80C limit without market risk, it is a dependable default.

Its reinvestment relief, which quietly lowers the effective tax on the interest, gives it an edge over a plain bank tax-saver FD that many savers overlook. That mix of safety, return and a softer tax hit keeps it a fixture of the January-to-March tax season.

Key takeaways

• The NSC pays 7.7% a year (FY2026-27 Q1), compounded annually and paid at maturity over a fixed 5-year term, with the rate locked at purchase.
• A ₹1 lakh certificate grows to about ₹1.44 lakh in five years.
• Minimum ₹1,000 in multiples of ₹100, no maximum; the amount qualifies for an 80C deduction up to ₹1.5 lakh.
• Reinvested interest for the first four years also earns 80C relief; only the final year's interest is fully taxed.
• The 80C deduction applies only under the old tax regime, so settle the regime choice first.
• There is a strict five-year lock-in, but the certificate can be pledged for a loan; rates reset quarterly, so confirm before buying.
