PPF vs NSC on ₹10 lakh: maturity, tax and return trade-offs

According to Mint, a ₹10 lakh comparison between the Public Provident Fund and National Savings Certificate hinges on more than the advertised interest rate. PPF cannot accept a ₹10 lakh lump sum because of its annual investment ceiling, while NSC can; the tax treatment then changes what the maturity value is actually worth to an investor. (Source: Mint)

What happened

PPF currently pays 7.1% annual interest and matures 15 years after the end of the financial year in which the account is opened. It can be extended in five-year blocks, with or without further contributions, and has partial withdrawal and loan provisions. Its exempt-exempt-exempt status means contributions qualify for Section 80C, while interest and maturity proceeds are tax-free. (Source: Mint)

NSC offers 7.7% for October-December 2026 with a five-year maturity. Unlike PPF, NSC accepts a ₹10 lakh lump sum, and the rate stays fixed for the tenure. Interest compounds annually and is paid at maturity, but it is taxed under the investor’s income tax slab. Mint’s example shows a ₹10 lakh NSC investment at 7.7% would mature at approximately ₹14.49 lakh after five years, including ₹4.49 lakh of interest before tax. (Source: Mint)

Both schemes qualify for Section 80C deductions up to ₹1.5 lakh a year, but only under the old tax regime. In NSC, interest accrued in the first four years is treated as reinvested and can be claimed under Section 80C, subject to the overall limit; the interest itself remains taxable. Fifth-year interest is taxable and is not treated as reinvested for another deduction. (Source: Mint)

Our analysis

The core difference is not just the modest rate gap; it is the tax status and lock-in. PPF’s EEE treatment means the entire accumulation escapes tax at contribution, accrual and withdrawal. That can make its lower headline rate more significant for investors in higher tax slabs who are building long-horizon savings. NSC’s higher fixed rate is dampened by slab taxation on the ₹4.49 lakh of estimated interest in Mint’s example. (Source: Mint)

The ₹1.5 lakh annual PPF cap means a ₹10 lakh target cannot be deployed at once; the same capital would have to be spread over multiple financial years. That forces a slower compounding path and changes the liquidity profile. NSC, by contrast, allows the full lump sum immediately into a fixed five-year tenure, which is useful if the goal is a defined short-to-medium horizon with predictable fixed accrual. (Source: Mint)

There is also a behavioural angle. NSC’s reinvested interest in the first four years can create Section 80C deductions only in the old regime, but investors must still pay tax on that interest as income. This can create a mismatch between the deduction claimed and the eventual cash outflow at maturity, particularly for those who do not track accrual-based tax. (Source: Mint)

What this could mean for you

• PPF account holders get tax-free interest and maturity proceeds, but a ₹10 lakh lump sum cannot be placed in one year; the account grows within the annual contribution cap and a 15-year lock-in. (Source: Mint)
• NSC investors can place ₹10 lakh at once at 7.7% for five years, but the estimated ₹4.49 lakh interest is added to taxable income, so the post-tax return depends on the slab. (Source: Mint)
• Old tax regime savers can use Section 80C deductions for both schemes, including reinvested NSC interest in the first four years, subject to the overall ₹1.5 lakh annual limit. (Source: Mint)
• Retirement-focused savers may value PPF’s EEE status more than NSC’s higher headline rate; those with a five-year lump-sum need may find NSC predictable but must account for annual tax liability.

What to watch next

• The next quarterly NSC rate reset, because the 7.7% applies to October-December 2026 and a change would affect only new investments, not existing holdings. (Source: Mint)
• Whether the old tax regime remains part of an investor’s filing strategy, since Section 80C deductions for both schemes are not available under the new regime. (Source: Mint)
• PPF extension rules at maturity, as the option to continue in five-year blocks with or without contributions determines long-term tax-free compounding.

Bottom line

The PPF-NSC choice is less about 7.1% versus 7.7% and more about lock-in, liquidity and post-tax treatment. In our view, PPF favours long-horizon tax-free accumulation, while NSC is a fixed-tenure lump-sum tool whose headline maturity value should be read after slab tax. (Source: Mint)
