April 5 is not just another deadline for Public Provident Fund (PPF) and Sukanya Samriddhi Yojana (SSY) investors – it is your last chance this year to ensure your money earns interest from April itself. Miss it by even one day, and your deposit will not earn any interest for this month, effectively reducing your annual returns.

For those investing up to Rs 1.5 lakh, the loss may look small at first – around Rs 888 in a year but over time, this adds up to more than Rs 1.23 lakh in completely tax-free income. In long-term investing, this is where timing quietly makes a big difference.

PPF follows a simple but strict rule:

• Interest is calculated on the lowest balance between the 5th and month-end

• Deposit on or before April 5 – full amount earns interest for April
• Deposit after April 5 – no interest for April on that amount

So even if you invest the same money, a one-day delay can cost you a full month’s return.

Here’s how timing impacts your returns:

• Invest before April 5

  Interest at 7.1 per cent – Rs 10,650 in a year

• Invest after April 5

  Interest for 11 months – Rs 9,762.50

• Difference – nearly Rs 888 lost in one year

If you follow the April 1–5 strategy every year:

• Over 15 years, you can earn over Rs 1,23,610 extra
• This entire amount is tax-free

That is the power of compounding working in your favour – simply because you invested early.

The government has kept the PPF interest rate unchanged at 7.1 per cent for the April–June 2026 quarter.

This continued stability makes PPF one of the most dependable long-term savings options, especially for conservative investors.

Even if you have opted for the new tax regime and do not get Section 80C benefits, PPF and SSY remain attractive because:

• Interest earned is fully tax-free
• Maturity amount is fully tax-free

Both schemes fall under the EEE (Exempt-Exempt-Exempt) category, making them among the few completely tax-efficient investments available.

• Deposit before the 5th of every month
• Ensure your money earns interest for that month

Sukanya Samriddhi Yojana continues to offer higher interest:

• 8.2 per cent interest rate (April–June 2026)
• Fully tax-free returns

• Available for girl children below 10 years
• 21-year maturity period
• Contributions required for 15 years only

If you are planning your investment, a lump sum deposit made on or before April 5 remains the most effective strategy, as it ensures your entire amount earns interest for the full financial year.
