South Indian Bank Fixed Deposits offer a secure investment avenue with competitive interest rates that appeal to conservative investors seeking capital protection. The bank provides an additional interest rate of 0.50% per annum for senior citizens across all tenure buckets, making it particularly attractive for retired individuals looking for stable income. With a low minimum investment threshold of just ₹1,000 and no maximum investment limit, these FDs are accessible to investors across all economic segments.
The bank offers multiple interest payout options including monthly, quarterly, half-yearly, annual, and cumulative interest payments to suit different customer requirements and cash flow needs. Depositors can avail loans against their fixed deposits up to 90% of the deposit value, providing crucial liquidity during financial emergencies without breaking the deposit. The auto-renewal facility ensures that funds continue to earn interest after maturity, while the nomination facility provides for smooth transfer of funds to beneficiaries.
The Regular Fixed Deposit scheme is available to all resident individuals and offers attractive interest rates for tenures ranging from 7 days to 10 years. Investors can choose from various interest payout frequencies including cumulative, monthly, quarterly, half-yearly, or annual options based on their income requirements and financial goals.
This specialised scheme is designed exclusively for individuals aged 60 years and above, offering an additional 0.50% interest rate above the regular FD rates across all tenures. The enhanced returns provide senior citizens with a stable and higher regular income to meet their post-retirement expenses, healthcare needs, and other financial requirements.
South Indian Bank's Tax Saver Fixed Deposit comes with a mandatory lock-in period of 5 years as per Income Tax regulations, with investments up to ₹1.5 lakh qualifying for tax deduction under Section 80C of the Income Tax Act, 1961. No premature withdrawals are permitted under this scheme except in case of the depositor's demise, and no loan facility is available against these deposits, ensuring the lock-in period is strictly maintained.
In the Cumulative Fixed Deposit scheme, the interest is compounded quarterly and reinvested with the principal amount, leading to a significantly higher maturity value compared to the initial investment due to the power of compounding. This option is perfect for investors who do not require regular interest income and are focused on long-term wealth accumulation for goals like children's education, marriage expenses, or retirement planning.
The Non-Cumulative Fixed Deposit scheme is designed for investors who require regular income from their investments to meet ongoing expenses, with interest payout options available monthly, quarterly, half-yearly, or annually as per the depositor's convenience. This scheme is particularly beneficial for retirees, senior citizens, and other individuals who depend on their investments for regular cash flow to cover living expenses, medical costs, or other recurring financial obligations.

Medium-term fixed deposits span tenures from 1 year to 2 years, offering attractive interest rates with regular customers earning up to 7.00% and senior citizens up to 7.50% for this tenure bracket.

Existing South Indian Bank customers can invest in fixed deposits through the bank's internet banking platform by logging into their account using their user ID and password. Once logged in, navigate to the 'Deposits' section and select the 'Open Fixed Deposit' option, which will display the various FD schemes available along with their current interest rates for different tenures. Choose the desired FD type, specify the investment amount, select the tenure from the available options, indicate the preferred interest payout frequency (cumulative, monthly, quarterly, etc.), and provide nominee details if required for succession planning and risk mitigation.
After entering all the required information, carefully review the details displayed on the confirmation screen, including the maturity date, applicable interest rate, interest payout frequency, and maturity amount to ensure accuracy. Authorise the transaction using the preferred authentication method such as internet banking password or OTP received on your registered mobile number, following which the investment amount will be debited from your linked savings account. Upon successful processing, the system generates a digital fixed deposit receipt immediately, which can be downloaded and saved for future reference, and an electronic confirmation is also sent to your registered email address and mobile number for records and documentation purposes.
To open a fixed deposit offline, visit your nearest South Indian Bank branch and collect a fixed deposit application form from the customer service desk or relationship manager. Fill the form completely and accurately in block letters, providing all required personal details, KYC information, FD specifics (amount, tenure, type), interest payout frequency preference, and nominee details with proper percentage allocation if multiple nominees are specified.
Submit the duly filled application form along with self-attested copies of KYC documents (PAN card, Aadhaar card, address proof, and passport-sized photographs) to the bank executive at the counter. Make the initial deposit through cash (subject to regulatory limits), cheque, or by transferring funds from your existing South Indian Bank savings account, and obtain an acknowledgement for your application submission.
South Indian Bank allows resident individuals, either singly or jointly, to open fixed deposit accounts, with joint accounts permitting up to three holders as per the bank's policy and operational guidelines. Senior citizens aged 60 years and above are eligible for special higher interest rates across all FD schemes, while minors can open fixed deposits through their natural guardians or legal representatives with proper documentation and identification.
The eligibility extends to various non-individual entities including Sole Proprietorship firms, Partnership Firms, Limited Liability Partnerships (LLPs), Private and Public Limited Companies, Clubs, and Associations with proper registration and operational documents. Registered Trusts and Societies are also eligible to invest in South Indian Bank fixed deposits, subject to submission of relevant registration certificates, trust deeds, and operational documents establishing their legal status and authority to invest.
For identity verification, a PAN card is mandatory for all applicants opening fixed deposits with South Indian Bank, along with other valid identity proofs such as Aadhaar card, Passport, Voter ID card, or Driving Licence as per regulatory requirements and the bank's policy. Address proof can be established through documents like Aadhaar card, Passport, utility bills (electricity, water, or gas connection bills not older than 3 months), property tax receipt, or bank account statements with recent transactions indicating the current address.
For non-individual entities, additional documents are required including Certificate of Incorporation/Registration, Memorandum and Articles of Association, Board Resolution authorising the investment and specifying authorised signatories, and PAN card of the entity. Partnership firms need to submit the Partnership Deed and authorisation letter from all partners, while Trusts must provide the Trust Deed, registration certificate, and resolution from trustees authorising the investment and specifying operating instructions.
The interest earned on South Indian Bank Fixed Deposits is fully taxable under the head "Income from Other Sources" as per the Income Tax Act, 1961, and must be included in the investor's total annual income, taxed according to their applicable income tax slab rate. The bank is required to deduct Tax Deducted at Source (TDS) at the rate of 10% if the total interest income from all fixed deposits with the bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens as per recent amendments to the Income Tax Act).
Investors whose total income is below the taxable limit can submit Form 15G (for individuals below 60 years) or Form 15H (for senior citizens aged 60 years and above) to the bank at the beginning of the financial year to avoid TDS deduction, provided they meet the specified conditions regarding total income and tax liability as per current regulations. For Tax Saver FDs, while the principal investment up to ₹1.5 lakh qualifies for deduction under Section 80C, the interest earned is taxable each year on accrual basis, meaning tax liability arises even though the interest is not received until maturity in cumulative options.
South Indian Bank permits premature withdrawal of fixed deposits before the completion of the agreed tenure, subject to the bank's specific terms and conditions and applicable penalties as mentioned in the FD application form and account opening documents. The bank typically charges a penalty of 1.00% on the contracted interest rate for the period the deposit was held, meaning the investor receives interest at a rate 1% lower than the original rate for the actual duration the funds remained with the bank.
Log in to your South Indian Bank internet banking account and navigate to the deposits section to access the fixed deposit application. Select your preferred FD type, tenure, and amount, then authorise the transaction to instantly create your fixed deposit with digital receipt.

Opt for cumulative FDs to benefit from quarterly compounding and select medium-term tenures of 1-2 years which typically offer the highest interest rates in the bank's portfolio. Senior citizens should always avail of the additional 0.50% interest and avoid premature withdrawals to prevent penalty charges that reduce overall returns.
