❓ Frequently Asked Questions (Master PPF Guide)

1. What is the Critical "5th-Day Deposit Rule" in PPF?

The single most common mistake made by PPF account holders is depositing money late in the month:

• How Interest is Calculated: Under PPF rules, interest is calculated on the lowest balance in your account between the close of the 5th day and the end of the month.
• The Golden Rule: Always deposit your monthly PPF installment on or before the 5th of every month.
• The Annual Lump Sum Hack: If depositing the maximum annual limit of ₹1,50,000 as a lump sum, deposit it between April 1st and April 5th to earn a full 12 months of compounding interest for that financial year!

2. What are the Minimum and Maximum Deposit Limits in PPF?

• Minimum Annual Deposit: ₹500 per financial year (to keep account active; a default fee of ₹50 + ₹500 arrear applies for reactivation).
• Maximum Annual Deposit: ₹1,50,000 per financial year across all PPF accounts held in an individual's name (including accounts opened on behalf of minor children).
• Any deposit exceeding ₹1,50,000 in a single financial year does not earn interest and is not eligible for tax deductions.

3. How Does the 15-Year Maturity and 5-Year Block Extension Work?

A PPF account matures after 15 full financial years from the end of the year in which the account was opened. Upon maturity, you have three options:

1. Option 1: Complete Closure & Withdrawal: Withdraw 100% of the accumulated corpus completely tax-free.
2. Option 2: Extend with Fresh Contributions (Form H): Extend the account in blocks of 5 years with fresh deposits. You must submit Form H within 1 year of maturity.
3. Option 3: Extend without Fresh Contributions (Default): Continue earning the sovereign interest rate on your full balance indefinitely without adding new money, with the ability to withdraw any amount once per year!

---

4. Can I Take a Loan Against My PPF Account?

YES (Years 3 to 6):

• Eligibility: Available from the 3rd financial year up to the 6th financial year from account opening.
• Maximum Loan Amount: Capped at 25% of the total balance standing at the end of the 2nd financial year preceding the year in which the loan is applied.
• Interest Rate: Charged at a concessional 1.0% above the prevailing PPF interest rate (e.g., $7.1% + 1.0% = 8.1%$). Must be repaid within 36 months.

---

5. What are the Partial Withdrawal Rules in PPF?

Starting from the 7th financial year, account holders can make one partial withdrawal per year:

• Maximum Withdrawal Ceiling: Up to 50% of the account balance at the end of the 4th preceding financial year, OR 50% of the balance at the end of the immediately preceding financial year (whichever is lower).
• All partial withdrawals are 100% tax-free.
