Key Takeaways
- A tax saving fixed deposit is a 5-year lock-in FD that qualifies for deduction under Section 80C, up to Rs 1,50,000 per financial year.
- Available only to resident individuals and HUFs filing under the old tax regime. Section 80C is not available under Section 115BAC (new regime).
- Interest earned is fully taxable as income from other sources every year on accrual basis. The FD falls under the EET (Exempt-Exempt-Taxed) category.
- No premature withdrawal, no loan against deposit, and cannot be pledged as collateral during the 5-year tenure.
- Current bank rates range from 6.50% (SBI, PNB) to 7.00% (HDFC, ICICI, Axis). Post Office NSC offers 7.70% with the same lock-in and 80C eligibility.
- TDS is deducted if annual interest exceeds Rs 40,000 (Rs 50,000 for senior citizens under Section 194A).
- NRIs are not eligible for tax saving FDs: only resident Indians can invest.
A tax saving fixed deposit remains one of the simplest instruments for risk-averse taxpayers looking to utilise the Section 80C deduction window. Unlike ELSS or equity-linked products, it carries zero market risk and offers a guaranteed return over a fixed tenure. However, the interest is fully taxable, the lock-in is rigid, and the effective post-tax yield may be lower than alternatives like PPF.
This guide covers eligibility, current interest rates across major banks, the tax treatment of interest income, and a head-to-head comparison with other Section 80C instruments so you can decide whether the tax saving FD fits your financial plan for FY 2026-27.

What Is a Tax Saving Fixed Deposit?
A tax saving FD is a term deposit with a mandatory 5-year lock-in period, offered by all scheduled commercial banks and certain post office schemes. The principal invested (up to Rs 1,50,000 in a year) qualifies for deduction under Section 80C of the Income Tax Act 1961.
Unlike regular fixed deposits that can be broken prematurely or used as collateral for loans, the tax saving variant comes with strict restrictions in exchange for the tax benefit. The government mandates these constraints to ensure that the investment is genuinely long-term and not merely a short-term parking strategy.
Key characteristics:
- Tenure: Exactly 5 years. Cannot be broken before maturity.
- Maximum qualifying amount: Rs 1,50,000 per financial year (combined 80C cap under Section 80CCE).
- Minimum investment: Varies by bank, typically Rs 1,000 to Rs 10,000.
- Interest payout: Monthly, quarterly, or cumulative (reinvested), depending on your choice. Tax treatment does not change regardless of payout frequency.
- Nomination: Facility available. If the depositor dies before maturity, the nominee can withdraw the full amount without penalty.
Who Can Invest: Eligibility
| Parameter | Requirement |
|---|---|
| Eligible assessees | Resident individuals and HUFs only |
| Companies, firms, LLPs | Not eligible |
| NRIs | Not eligible |
| Tax regime | Old regime only (Section 80C not available under 115BAC) |
| Joint holding | Deduction available only to the first holder |
| Minors | Can invest through guardian; deduction claimed by guardian |
If you have opted for the new tax regime under Section 115BAC for FY 2026-27, investing in a tax saving FD provides no deduction benefit. The 5-year lock-in still applies, making it a poor choice for new regime filers.
Current Interest Rates: Tax Saving FD (July 2026)
The table below shows approximate interest rates on 5-year tax saving fixed deposits offered by major banks and post office schemes. Rates are subject to revision; confirm with your bank before investing.
| Institution | Rate (General) | Rate (Senior Citizen) | Lock-in |
|---|---|---|---|
| SBI | 6.50% | 7.00% | 5 years |
| HDFC Bank | 7.00% | 7.50% | 5 years |
| ICICI Bank | 7.00% | 7.50% | 5 years |
| PNB | 6.50% | 7.00% | 5 years |
| Axis Bank | 7.00% | 7.50% | 5 years |
| Post Office NSC | 7.70% | 7.70% | 5 years |
| Post Office Time Deposit (5Y) | 7.50% | 7.50% | 5 years |
Note: Senior citizen rates typically carry an additional 0.25% to 0.50% premium over the general rate at most banks. Post Office schemes do not differentiate between age groups.
Features and Restrictions
What you get
- Guaranteed, fixed returns with no market risk
- Section 80C deduction on principal invested (old regime)
- Nomination facility for seamless transfer on death
- Available at every scheduled bank branch: no paperwork complexity
What you cannot do
- No premature withdrawal: The deposit cannot be broken before 5 years under any circumstance (except death of the depositor).
- No loan against deposit: Banks will not provide an overdraft or loan against a tax saving FD.
- No pledge or collateral use: The FD certificate cannot be hypothecated, assigned, or used as security.
- No auto-renewal: After maturity, the amount moves to a savings account or converts to a regular FD at prevailing rates. It does not auto-renew as a tax saving FD.
Tax Treatment of Interest
This is the critical area where the tax saving FD loses its appeal compared to PPF or Sukanya Samriddhi. While the principal qualifies for deduction, the returns do not enjoy any tax shelter:
- Interest is fully taxable as "Income from Other Sources" in your ITR, every year, on accrual basis.
- The bank deducts TDS under Section 194A if total interest across all FDs in that bank exceeds Rs 40,000 in a financial year (Rs 50,000 for senior citizens).
- Even if you choose the cumulative option (no periodic payout), interest is taxed each year on accrual, not at maturity.
- Tax saving FDs are classified as EET (Exempt-Exempt-Taxed): the principal gets a deduction, but the interest is fully taxed at your marginal slab rate.
Section 80TTB benefit for senior citizens
Resident senior citizens (60 years and above) can claim an additional deduction of Rs 50,000 under Section 80TTB on interest income from all deposits (FDs, RDs, savings accounts combined). This effectively shelters a portion of the FD interest from tax. Section 80TTB is also available only under the old tax regime.
Comparison with Other Section 80C Instruments
| Instrument | Return | Lock-in | Tax on Returns | Risk |
|---|---|---|---|---|
| Tax Saving FD | 6.50%-7.00% | 5 years | Fully taxable (EET) | Zero |
| PPF | 7.10% | 15 years | Exempt (EEE) | Zero |
| ELSS Mutual Fund | Market-linked (10-14% historical) | 3 years | LTCG above Rs 1.25 lakh taxed at 12.5% | High (equity) |
| NSC (National Savings Certificate) | 7.70% | 5 years | Interest taxable (reinvested interest deductible under 80C until Year 4) | Zero |
| Sukanya Samriddhi Yojana | 8.20% | Until girl child turns 21 | Exempt (EEE) | Zero |
| Life Insurance (endowment) | 4-6% effective | 10-20 years | Exempt if conditions met (Section 10(10D)) | Low |
| EPF (employee share) | 8.25% | Until retirement | Exempt (EEE) | Zero |
Key observations
- PPF beats tax saving FD on post-tax returns because PPF interest is entirely exempt. The trade-off: 15-year lock-in vs 5 years.
- NSC offers a higher rate (7.70%) with the same 5-year lock-in. Additionally, reinvested interest in Years 1-4 qualifies for fresh 80C deduction. NSC is often the better choice for fixed-income investors.
- ELSS has the shortest lock-in (3 years) and potentially higher returns, but carries equity market risk.
- Sukanya Samriddhi (8.20%, EEE) is the highest-yielding safe instrument, but restricted to parents of a girl child below 10 years.
When Does a Tax Saving FD Make Sense?
A tax saving FD is a reasonable choice when:
- You are a risk-averse investor who wants zero market exposure.
- You file under the old tax regime and need to fill the Rs 1,50,000 Section 80C basket.
- You want guaranteed, fixed returns with no NAV fluctuation.
- Your 80C bucket is partially filled (EPF, insurance, tuition) and you need a top-up with a shorter lock-in than PPF.
- You prefer bank deposits over post office visits (otherwise, NSC at 7.70% is better).
It does not make sense when:
- You are on the new regime: no deduction benefit, and the lock-in is unnecessary.
- You can tolerate equity risk: ELSS offers higher long-term potential with a shorter 3-year lock-in.
- You want tax-free returns: PPF or Sukanya Samriddhi are EEE instruments.
Joint Holding and Deduction Rules
When a tax saving FD is held jointly:
- The Section 80C deduction is available only to the first holder (primary depositor).
- The second holder cannot claim any portion of the deduction.
- Interest income is also assessable in the hands of the first holder unless the contribution is clearly from the second holder's funds (in which case, proportional income allocation applies under Section 60/64 clubbing provisions).
Effective Post-Tax Return Calculation
To understand the real cost of taxable interest, consider an investor in the 30% slab (plus 4% cess, effective 31.2%):
- Tax saving FD at 7.00%: Post-tax yield = 7.00% x (1 - 0.312) = 4.82%
- PPF at 7.10%: Post-tax yield = 7.10% (entirely exempt under EEE)
- NSC at 7.70%: Post-tax yield = 7.70% x (1 - 0.312) = 5.30% (but reinvested interest gets 80C deduction, improving effective yield)
For a 20% slab taxpayer (effective 20.8%), the post-tax yield on a 7.00% FD is approximately 5.54%. The lower your tax bracket, the less damaging the taxable interest becomes.
Practical Tips
- Compare NSC before committing: The Post Office NSC offers 7.70% with the same 5-year lock-in and 80C eligibility. Unless you need the convenience of a bank FD or periodic interest payouts, NSC often delivers better post-tax returns.
- Submit Form 15G/15H: If your total income is below the basic exemption limit, submit Form 15G (or Form 15H for senior citizens) to the bank to avoid TDS deduction on interest.
- Track accrued interest in ITR: Even if you selected the cumulative option, report accrued interest each year in Schedule OS of your ITR. Do not wait until maturity.
- Plan around the Rs 1.5 lakh cap: Your EPF contribution, tuition fees, and insurance premiums already consume part of the 80C limit. Calculate the remaining headroom before investing in a tax saving FD.
- Set a maturity reminder: Since there is no auto-renewal, the proceeds after 5 years may earn negligible savings-account interest if you do not reinvest promptly.
Frequently Asked Questions
Can I break a tax saving FD before 5 years?
No. Premature withdrawal is not permitted under any circumstance during the lock-in period. The only exception is death of the depositor, in which case the nominee or legal heir can claim the full maturity amount.
What happens if I switch to the new regime after investing?
The FD lock-in continues regardless of regime choice. You will not get a deduction reversal or penalty, but you simply lose the tax benefit for that year. The interest remains taxable irrespective of regime.
Can I open multiple tax saving FDs?
Yes, you can open tax saving FDs at different banks in the same financial year. However, the combined 80C deduction across all instruments (including EPF, PPF, insurance, tuition) remains capped at Rs 1,50,000.
