What is a Tax-Saving Fixed Deposit?
A fixed deposit account offering the facility to claim deductions under Section 80C of the Income Tax Act, 1961, is known as a tax-saving fixed deposit. This type of term deposit is an attractive investment in terms of safety, deduction and long-term investment approach.
These deposit accounts have a fixed lock-in period of 5 years. The other features of a tax-saving fixed deposit are the same as regular fixed deposits. Tax-saving fixed deposit accounts can have maturity up to 10 years. It can be a suitable investment with a long-term approach to compound the returns.
How Does it Work?
Similar to other deposits, a tax-saving fixed deposit collects investment income from the account holder and compounds its returns over the maturity period. Here is the detailed process:
- Investors can complete the ‘Know Your Customer’ (KYC) process and open a fixed deposit account.
- Based on the maturity period and interest frequency, interest compounds over the period.
- After a minimum period of 5 years, investors can withdraw their investments before the decided maturity.
- This income, up to ₹1.5 lakhs, can become a deduction under Section 80C. The remaining amount above ₹1.5 lakhs will be added to other incomes to be taxed as per the income tax slab.
- However, tax will be deducted by the institution before transferring the interest amount. As of January 2025, Tax Deducted from Source (TDS) is 10% on interest as follows:
- Regular investors: Interest above ₹40,000
- Senior citizen investor: Interest above ₹50,000
Benefits and Drawbacks of Tax-Saving Fixed Deposit
Investors should evaluate the positive and negative side of an investment before deciding its suitability.
Benefits | Drawbacks |
Due to its lock-in period, sufficient time is given for investment to grow through compounding. | Its interest may not match market returns. Therefore, inflation may outpace the FD returns. |
Investment in the bank FD accounts can be considered secure, as deposits up to ₹5 lakhs are insured. | Investors cannot withdraw the investment before 5 years as it is the mandatory lock-in period. |
Income tax deduction up to ₹1.5 lakhs. | Interest above ₹40,000 will be taxable. |
A wide range of options with different interest rates and from different issuers are available for investment. | Pre-mature withdrawal may cost investors the interest for the rest period up to maturity. |
Investing in these FDs may not be suitable for all types of investors. Therefore, investors can allocate a part of their investment rather than locking a large part of their investment.
Consider this Before Opting for Tax-Saving Fixed Deposit
Investors should also check their suitability with the investment rather than opting for it only for the deduction purpose as it locks the investment for 5 years. Here are some brief points to consider before selecting the investment:
- Compare the different available tax-saving fixed deposit products from different issuers.
- Evaluate the current asset allocation and nature of the portfolio. Moreover, investors should also check their investment objectives. If the purpose is short-term, the 5-year lock-in may not be suitable.
- Calculate the potential tax implication at the end of maturity and check whether the deduction can be claimed.
- Invest in tax-saving fixed deposits for diversification and capital preservation. It may not be feasible for all types of investors to allocate a significant part of their portfolio as the fixed deposit interest rate can be low.
Conclusion
The tax-saving fixed deposit is a term deposit account that allows investors to claim income tax deductions under section 80C. It can be a potential avenue for investors with a potentially long-term financial objective. However, this instrument is charged 10% TDS if it exceeds the threshold of ₹40,000. Investors can calculate their potential income tax deductions to decide their investment.
