Module G: Interactive FAQ
What was the exact PPF interest rate for SBI in 2018-19?
The SBI PPF interest rate for financial year 2018-19 was 7.6% per annum, compounded annually. This rate was notified by the Ministry of Finance through their quarterly small savings scheme revisions. The rate was slightly lower than the previous year’s 7.8%, reflecting the overall downward trend in interest rates during that period.
Can I deposit more than ₹1.5 lakh in my PPF account?
No, the maximum deposit limit for a PPF account is ₹1.5 lakh per financial year. Any amount deposited beyond this limit will not earn any interest and will not be eligible for tax benefits under Section 80C. The excess amount can be withdrawn at any time without attracting any interest.
How is PPF interest calculated monthly?
PPF interest is calculated on the minimum balance in your account between the 5th and the last day of each month. The actual interest crediting happens annually at the end of the financial year. For example, if you deposit ₹10,000 on the 4th of a month, it will earn interest for that month, but if deposited on the 6th, it won’t count toward that month’s interest calculation.
What happens if I don’t deposit the minimum ₹500 in a year?
If you fail to deposit the minimum ₹500 in any financial year, your PPF account will become inactive. To reactivate it, you’ll need to pay a penalty of ₹50 for each year of default along with the minimum deposit of ₹500 for each defaulted year. The account will then be restored to active status.
Can I have multiple PPF accounts?
No, an individual can have only one PPF account in their name. However, you can open a separate account for your minor child. The combined deposit in both accounts cannot exceed ₹1.5 lakh per financial year. Having multiple accounts in your own name is against PPF rules and can lead to closure of additional accounts without any interest.
What are the tax benefits of PPF?
PPF offers triple tax benefits (EEE status):
- Contributions are eligible for deduction under Section 80C (up to ₹1.5 lakh)
- Interest earned is completely tax-free
- Maturity amount is also tax-free
This makes PPF one of the most tax-efficient investment options in India.
How can I extend my PPF account after 15 years?
After the initial 15-year term, you can extend your PPF account in blocks of 5 years indefinitely. You need to submit Form H to your bank before the account matures. During the extension period, you can continue making deposits (subject to the ₹1.5 lakh annual limit) and earn interest. If you don’t extend, the account will continue to earn interest but you won’t be able to make fresh deposits.
