Taxation on CSB Bank FD Interest

As of FY 2025-26, interest earned on CSB Bank Fixed Deposits (FDs) is fully taxable under the heading “Income from Other Sources.” TDS is deducted at 10% if the total FD interest exceeds ₹50,000 in a financial year (₹1 lakh for senior citizens). If the investor fails to submit their PAN, TDS is deducted at 20%. To avoid unnecessary deductions, eligible individuals can submit Form 15G/15H (for senior citizens) at the start of the financial year, provided their total income is below the taxable threshold. Interest must still be reported in the income tax return. Besides, deposits under the CSB Tax Savings Support scheme (tax saver FD) are eligible for income tax deduction up to ₹1.5 lakh under Section 80C of the Income Tax Act.

Key Benefits of CSB Bank Fixed Deposit

Here are some of the key benefits of opening a CSB Bank FD.

• Low Minimum Deposit Requirement: You can start a CSB Bank FD with a minimum of just ₹1,000, making it accessible to small savers and first-time investors.
• Senior Citizen Benefits: Senior citizens get up to 0.50% extra interest on select schemes and enjoy higher annualised yields through the Acharya Deposit option.
• Nomination & Joint Holding: All FDs offer nomination facilities and can be opened individually, jointly, or in the name of minors (under guardianship).
• Premature Withdrawal Penalty: CSB Bank typically applies a 1% reduction in the applicable interest rate as a penalty if an FD is withdrawn before its maturity date.
• Loan & Withdrawal Options: Loans against FDs are available. The bank may levy applicable interest or charges on loans against FD.
• Sweep-In and Sweep-Out Facility: CSB Bank provides a Flexi Fixed Deposit facility with sweep-in and sweep-out features. When a customer’s savings or current account balance exceeds a defined threshold, the surplus is automatically transferred into a fixed deposit. If the balance falls below a minimum set level, funds are swept back from the FD into the account.
