Child's PPF Account: How Parents Can Build a Tax-Efficient Corpus Worth Lakhs by the Time Their Child Turns 18

A child's financial future often requires years of preparation, particularly when parents are planning for higher education, major life milestones or long-term financial security. Starting a savings plan early can provide a valuable foundation for meeting these expenses.
Child's PPF Account How Parents Can Build a Tax-Efficient Corpus Worth Lakhs by the Time Their Child Turns 18


The Public Provident Fund (PPF) is a government-backed savings scheme that offers a long investment horizon and tax-efficient returns. Parents can open an account for a minor and make regular contributions, subject to prescribed rules and limits.

How to Open a PPF Account for a Minor Child

The Public Provident Fund is a long-term savings scheme backed by the Government of India. It is available through authorised banks and post offices and can be used to build a financial reserve for a child.


A parent or legal guardian can open and operate a PPF account on behalf of a minor. However, an individual is generally permitted to maintain only one PPF account in their own name. The account opened for a child is separate from the parent's personal account, although the contribution limits apply collectively.

Parents who wish to open a minor PPF account can follow these steps:


  • Visit an authorised bank branch or a nearby post office offering PPF services.
  • Obtain the relevant account opening application form and complete the required details.
  • Submit the necessary KYC documents, including identity proof, address proof and photographs, as applicable.
  • Provide the child's birth certificate or other prescribed documents establishing the minor's identity and age.
  • Make the initial deposit according to the scheme's requirements.
Some banks also provide an online account opening facility through internet banking or mobile banking. Parents should check the availability of this service with their bank.

Once the child turns 18, the account must be updated to reflect their status as an adult account holder. The account holder will need to submit the prescribed application and supporting KYC documents to the bank or post office.

PPF Investment Limit for Children: Can Both Parents Deposit Rs 3 Lakh?

One of the most important aspects of opening a PPF account for a child is understanding the annual contribution limit.

Parents may assume that the father can deposit Rs 1.5 lakh and the mother can contribute another Rs 1.5 lakh, allowing the child to receive Rs 3 lakh annually. However, this is not permitted under the applicable PPF rules.


The maximum contribution allowed across an individual's own PPF account and accounts maintained on behalf of minor children is Rs 1.5 lakh in a financial year.

This means that the total deposits made by both parents into a child's PPF account cannot exceed the prescribed annual limit. The same restriction applies when parents contribute to their own accounts alongside the child's account.

The following examples explain how the contribution limit works.

Contribution arrangementTotal depositWithin the annual limit?
Father deposits Rs 1.5 lakh and mother deposits Rs 1.5 lakh into the child's accountRs 3 lakhNo
Both parents contribute Rs 75,000 eachRs 1.5 lakhYes
Father deposits Rs 1 lakh in his account and Rs 50,000 in the child's accountRs 1.5 lakh combinedYes
Father and mother each deposit Rs 1 lakh into the child's accountRs 2 lakhNo
Parents should also remember that the annual PPF contribution limit is not an additional allowance for each minor child. Contributions across eligible accounts must remain within the applicable aggregate limit.

How Are Contributions to a Child's PPF Account Taxed?

Deposits made by parents into a minor's PPF account are generally treated as gifts to the child. The interest earned on the account is tax-free under the PPF scheme.


However, parents should distinguish between the tax treatment of PPF interest and the deduction available for contributions.

Eligible PPF contributions can qualify for a deduction under Section 80C of the Income-tax Act, subject to the overall limit and the applicable tax regime. This deduction is available under the old tax regime, not the new tax regime.

The annual deduction limit under Section 80C is Rs 1.5 lakh, which includes eligible contributions to the parent's own PPF account and the child's account, along with other qualifying investments.

The PPF interest exemption is a separate benefit. Interest earned on a PPF account remains tax-free under the scheme's applicable provisions.

Understanding these distinctions can help parents avoid excess deposits and plan their investments more effectively.


How Much Can Your Child's PPF Account Grow by Age 18?

The long-term value of a PPF investment depends on the contribution amount, the interest rate and the period for which the account remains invested.

For illustration, consider annual investments of Rs 50,000, Rs 1 lakh and Rs 1.5 lakh over 18 years, assuming an interest rate of 7.1% throughout the period.

Illustrative calculations assume contributions are made at the beginning of each year. Actual returns will depend on prevailing interest rates and the timing of deposits.

Annual investment: Rs 1.5 lakh

Rs 55.14 lakh

Estimated corpus after 18 years


Total contributions

Rs 27 lakh

Estimated interest

Rs 28.14 lakh

Parents investing Rs 1.5 lakh annually could accumulate an estimated Rs 55.14 lakh by the time the child turns 18, provided the assumed interest rate remains unchanged.


The same annual contribution could be divided into monthly deposits of Rs 12,500. However, the actual maturity amount may differ because the timing of monthly deposits affects the interest earned.

Annual investment: Rs 1 lakh

Rs 36.76 lakh

Estimated corpus after 18 years

Total contributions

Rs 18 lakh


Estimated interest

Rs 18.76 lakh

With an annual investment of Rs 1 lakh, the estimated maturity value could reach approximately Rs 36.76 lakh after 18 years. Parents could also make monthly deposits of around Rs 8,333 to distribute the investment throughout the year.

Annual investment: Rs 50,000

Rs 18.38 lakh

Estimated corpus after 18 years


Total contributions

Rs 9 lakh

Estimated interest

Rs 9.38 lakh

A smaller contribution of Rs 50,000 a year could still build an estimated corpus of Rs 18.38 lakh over 18 years. This amount could be invested through monthly deposits of approximately Rs 4,167.


These figures are illustrations rather than guaranteed maturity amounts. The PPF interest rate is determined periodically by the government and may change during the investment period.

Can a Child's PPF Account Become a Retirement Corpus Worth Crores?

A PPF account does not necessarily have to be closed when the child reaches adulthood.

The scheme has an initial maturity period of 15 years from the end of the financial year in which the account was opened. After maturity, the account holder can extend it in five-year blocks, subject to the prescribed continuation rules.

This creates an opportunity for the child to continue saving after turning 18 and potentially use the account for long-term financial goals, including retirement.

For example, if an investment of Rs 1.5 lakh is made annually for 50 years, assuming a constant interest rate of 7.1% and contributions at the beginning of each year, the illustrative accumulated corpus could exceed Rs 6.75 crore.


The estimated total contributions over this period would be Rs 75 lakh, with the remaining amount arising from accumulated interest.

Similarly, the following illustrations show the potential value of continued investments:

Annual contributionEstimated corpus after 50 years
Rs 1.5 lakhRs 6.75 crore
Rs 1 lakhRs 4.51 crore
Rs 50,000Rs 2.25 crore
These projections assume the same interest rate over five decades. Actual returns could be significantly different because PPF interest rates may change over time. The account holder must also comply with the scheme's continuation and contribution requirements.

Why Parents Should Start Saving Early

A PPF account can be a useful option for parents seeking a government-backed savings instrument for their children's future.

Starting early gives investments more time to accumulate interest. Regular contributions, even when relatively modest, can gradually build a sizeable corpus.


However, parents should assess their financial circumstances before committing to long-term savings. They should also maintain adequate emergency funds and consider other suitable investment avenues based on their child's future requirements.

The key is to understand the scheme's contribution restrictions, taxation provisions and maturity rules before opening the account.
