What Happens to NSC After Maturity — Withdrawal, Extension & Tax

Your National Savings Certificate has completed its 5-year term. The maturity date is printed on the certificate itself. Now you need to know: what happens next, how do you get your money, can you extend it, and what happens to the interest if you leave it unclaimed?

Can NSC Be Extended After 5 Years?

No. NSC does not have an extension option. Unlike PPF, which can be extended in 5-year blocks, an NSC certificate simply matures at the end of its term. There is no facility to roll it over or continue it at the same interest rate.

If you want to reinvest, you purchase a new NSC certificate — which will be issued at the current interest rate prevailing at the time of purchase, not the rate from your original investment. As of Q1 FY 2026-27, the NSC interest rate is 7.7% p.a.

What Happens If You Don't Withdraw NSC After Maturity?

If you do not encash your NSC on or after the maturity date, the amount does not sit idle at the NSC rate. Instead, it earns interest at the Post Office Savings Account (POSA) rate — currently 4% p.a. — for a maximum of 2 years from the maturity date.

After those 2 years, no further interest is earned at all. The amount simply sits at the post office waiting to be claimed, with no return accruing.

This is a significant loss if you forget. An NSC earning 7.7% that silently drops to 4% — and then to 0% — is one of the most common quiet losses Indian families face with Post Office investments. If you have an NSC approaching maturity, set a reminder to withdraw promptly.

How to Withdraw NSC After Maturity

You can encash a matured NSC at any post office in India — you do not need to go to the branch where it was originally purchased. This is particularly useful if you have moved since buying the certificate.

At a CBS-enabled post office (faster)

Most post offices now operate under the Core Banking Solution (CBS) platform. At a CBS-enabled branch the process is faster:

• Submit the original NSC certificate and valid photo ID (Aadhaar, PAN, passport)
• The dealing official verifies your details through the CBS system with the issuing branch
• Payment is processed immediately after successful verification
• Amount is credited to your post office savings account or paid by cheque

At a non-CBS post office (takes longer)

If the encashing post office is not on CBS, the process takes 10–12 days:

• Submit a handwritten maturity claim with the original NSC certificate, your identity slip (issued at the time of purchase, if you have it), and valid photo ID
• If you have the identity slip, processing is faster
• Without the identity slip, the encashing post office verifies with the issuing branch's divisional office — this is the step that adds time
• Once verified, payment is issued by cheque

Documents to carry

• Original NSC certificate (mandatory)
• Identity slip issued at purchase (if available — speeds up processing)
• Valid photo ID — Aadhaar card, PAN card, or passport
• If encashing at a different post office from where it was issued: also carry your full name, address at the time of purchase, serial number, and issue date

If you have lost the NSC certificate

You can apply for a duplicate certificate at the post office using Form NC-29. If you have a photocopy of the original, the process is simpler. Once the duplicate is issued, you can encash it normally.

Tax on NSC Maturity — What You Actually Owe

NSC has a specific tax treatment that many investors misunderstand:

Years 1 to 4 interest — deemed reinvested, 80C-eligible: The interest credited in each of the first four years is treated as reinvested into the NSC. This means you can claim it as a fresh investment under Section 80C each year (subject to the overall ₹1.5 lakh annual cap). Most people who hold NSC in tax-saving portfolios do this annually.

Year 5 interest — taxable at your slab rate: The interest earned in the fifth and final year is not deemed reinvested. It is taxable as income from other sources at your applicable income tax slab rate in the year of maturity.

No TDS: The post office does not deduct TDS on NSC maturity proceeds. You receive the full amount and are responsible for declaring and paying tax on the year-5 interest when filing your return.

The principal at maturity: Not taxable — it is a return of your original investment.

What to Do With the Maturity Amount

If you want to continue earning at the current NSC rate, purchase a new certificate immediately after encashing the old one. The new certificate will earn interest at the rate prevailing on the date of purchase — which may be higher or lower than your original rate depending on when the government last revised it.

NSC is particularly useful for families who want guaranteed returns with 80C tax benefit and no market risk. If your tax-saving requirement and risk profile remain the same, rolling the maturity amount into a fresh NSC is the simplest path.
