EEE Tax Benefit Explained

PPF enjoys triple exemption:

1. Investment — qualifies for Section 80C deduction (up to ₹1,50,000)
2. Interest — completely tax-free every year
3. Maturity — entire amount is tax-free on withdrawal

For someone in the 30% tax bracket, PPF’s effective pre-tax equivalent return is approximately 10.14% — making it extremely competitive against taxable alternatives.

Partial Withdrawal and Loan Rules

• Partial withdrawal: Allowed from Year 7 onwards (up to 50% of balance at end of Year 4)
• Loan against PPF: Available from Year 3 to Year 6 (up to 25% of balance at Year 2)
• Premature closure: Only after Year 5, for serious illness or higher education (1% interest penalty)
• Extension: After 15 years, extend in 5-year blocks (with or without contributions)

Tips to Maximize PPF Returns

1. Invest before April 5th — interest calculated on minimum balance between 5th and month-end
2. Invest full ₹1,50,000 — don’t leave money on table
3. Lump sum in April vs monthly — full year’s investment earns interest for 12 months
4. Continue after 15 years — extension with contribution keeps compounding

FAQ

Q: What is the maximum PPF investment per year? A: ₹1,50,000 per financial year. Deposits can be made in lump sum or up to 12 installments. Minimum is ₹500/year to keep the account active.

Q: Can NRIs open a PPF account? A: NRIs cannot open new PPF accounts. Existing accounts (opened before becoming NRI) can continue till maturity but cannot be extended. Interest rate drops to savings account rate.

Q: Is loan against PPF a good idea? A: Generally no — you pay interest on the loan while your PPF earns less. Only useful for short-term emergencies when you can’t access other credit.

Q: What happens if I don’t invest minimum ₹500 in a year? A: Account becomes inactive. To reactivate, pay ₹500 for each inactive year plus ₹50 penalty per year. Interest continues to accrue on existing balance.

Q: PPF or ELSS mutual fund — which is better for 80C? A: PPF for guaranteed tax-free returns with zero risk. ELSS for potentially higher returns (12-15%) with market risk and only 3-year lock-in. Many investors split between both.
