Frequently asked questions
What is the Sukanya Samriddhi interest rate now?
8.2% a year for October–December 2026, tax-free. The government reviews it every quarter and the new rate applies to the whole balance, so it is not locked for 21 years.
What is the maximum amount in Sukanya Samriddhi?
With the maximum ₹1.5 lakh a year (₹12,500 a month) paid by 5 April for 15 years, the account grows to about ₹71.82 lakh at 21 years, if 8.2% stays the same. You invest ₹22.5 lakh; about ₹49.32 lakh is interest.
Can I exit Sukanya Samriddhi after 15 years?
No. Deposits stop after 15 years but the account matures 21 years from the date of opening. Before that, money can come out only for education (up to 50% after age 18 or Class 10), marriage (closure from age 18), hardship (after 5 years) or the girl’s death.
Do I need to extend Sukanya after 15 years?
No form is needed. From year 16 to 21 interest keeps compounding automatically. Sukanya cannot be extended after 21 years; it matures and is paid out.
Can I open Sukanya Samriddhi for a third daughter?
Only two accounts per family are allowed. The exception is twins or triplets in the first or second birth, with an affidavit and birth certificates.
Why deposit before 5 April?
Interest is calculated each month on the lowest balance between the 5th and month-end. Money deposited by 5 April earns for all 12 months. At the maximum, paying by 5 April gives about ₹5.44 lakh more than paying in March.
Is Sukanya Samriddhi useful in the new tax regime?
The ₹1.5 lakh deduction (Section 123 of the Income Tax Act 2025, earlier 80C) is available only in the old regime, but interest and the maturity amount are tax-free in both regimes.
