Tax on FD: How Fixed Deposit Interest Is Taxed and How Tax-Saver FDs Work
When people search for tax on fd, two distinct questions get mixed together. The first is how the government taxes interest earned on an ordinary fixed deposit. The second is how a dedicated five-year tax-saving deposit works to reduce your taxable income.
These are opposite sides of the same coin. A regular fixed deposit is an investment where your interest is subject to tax every year. A tax-saving deposit is a specialized instrument that offers an upfront deduction on the principal you invest, while still taxing every rupee of interest you earn along the way. Understanding how direct tax rules treat both sides prevents unexpected tax bills and avoids locking your money into products you cannot access.

How fixed deposit interest is actually taxed
Fixed deposit interest does not receive special concessional tax treatment. Unlike qualifying long-term equity capital gains, which enjoy dedicated annual exemptions and lower rates, fixed deposit interest is treated as ordinary income.
Under the Income-tax Act, 2025, interest earned on fixed deposits is classified under the head Income from Other Sources.
The tax treatment follows three practical rules:
Taxed at Your Applicable Slab Rate: The interest earned during the tax year is added to your total income. It is taxed at whatever marginal income tax bracket applies to you (such as 5%, 10%, 15%, 20%, or 30%, depending on your chosen tax regime).
Method of Accounting (Accrual vs Cash): Under direct tax rules, interest is taxable based on the method of accounting regularly employed by the taxpayer. However, banking institutions report cumulative interest annually in the Annual Information Statement (AIS) on an accrual basis. Declaring interest annually as it accrues prevents severe tax compounding spikes in the year the deposit matures.
No Inflation Indexation: You do not receive indexation benefits on fixed deposit interest. If inflation is 5.0% and your deposit pays 6.8%, you pay tax on the full nominal 6.8%, eroding your real purchasing power.

The TDS rules: what institutions deduct and what you still owe
| Payer Category | Standard Depositor TDS Threshold | Senior Citizen TDS Threshold (Aged 60+) | Mandatory TDS Rate (With Valid PAN) | Rate Without Valid PAN |
|---|---|---|---|---|
| Banking Companies | Above ₹50,000 per tax year | Above ₹1,00,000 per tax year | 10% | 20% |
| Co-operative Banks | Above ₹50,000 per tax year | Above ₹1,00,000 per tax year | 10% | 20% |
| Notified Post Office Deposits | Above ₹50,000 per tax year | Above ₹1,00,000 per tax year | 10% | 20% |
| Ordinary Corporate Deposits | Above ₹10,000 per tax year | Above ₹10,000 per tax year | 10% | 20% |
| Qualifying Housing Finance Companies | Subject to statutory criteria | Subject to statutory criteria | 10% | 20% |
Important Statutory Qualifications on Thresholds
The banking thresholds apply to the aggregate interest earned across all branches of the same banking company where Core Banking Solutions (CBS) are adopted. If an institution has not adopted CBS, aggregation across branches does not automatically apply under the statutory terms.
Furthermore, direct tax provisions distinguish between general corporate deposits and qualifying housing finance companies. While ordinary corporate deposits operate under the baseline ₹10,000 threshold, certain qualifying housing finance entities covered under statutory notes may fall within the bank-like threshold framework. Depositors should verify the exact statutory classification of their deposit issuer.
The Differential Tax Example
To see why TDS is not the final tax, consider an illustrative calculation for a resident individual in the 30% tax bracket earning ₹80,000 in interest from an eligible commercial bank:
The bank deducts 10% TDS under Section 393 on the interest: ₹8,000.
The bank credits ₹72,000 net interest and reports the ₹8,000 credit in Form 26AS and AIS records.
The investor’s illustrative tax rate is 30% plus 4% health and education cess, making the base tax rate 31.2%.
Total illustrative tax due on ₹80,000 interest: ₹24,960.
Remaining balance payable at return filing: $₹24,960 – ₹8,000 = \mathbf{₹16,960}$.
If the taxpayer assumes that the bank’s deduction settled the debt, the undeclared income can create tax discrepancies during return processing, potentially leading to rectification demands.

Form 121: preventing TDS when your total tax liability is nil
If your total estimated taxable income for the year leads to zero net tax liability, having a bank deduct 10% TDS forces you to file an income tax return simply to claim a refund.
For Tax Year 2026-27 under the Income-tax Act, 2025, the Central Board of Direct Taxes replaced historical Forms 15G and 15H with a single consolidated declaration: Form No. 121, framed under Section 393(6) and Rule 211.
Eligibility Rules for Form 121
Form 121 allows eligible resident individuals and Hindu Undivided Families (HUFs) to receive interest without tax deduction if they satisfy statutory conditions:
Resident Individuals Below 60 Years and HUFs: You can submit Form 121 only if two tests are met: the tax on your estimated total income for the tax year is nil, and the aggregate income covered by the declaration does not exceed the applicable basic tax exemption limit.
Resident Senior Citizens (Aged 60 and Above): Senior citizens have a more flexible condition. A resident senior citizen can submit Form 121 as long as the tax on their estimated total income is nil, even if their total interest income exceeds the basic exemption threshold.
How and When to Submit Form 121
Form 121 should be furnished to each payer institution before the interest is credited or paid, or at the start of the tax year.
Most scheduled banks provide digital submission tools inside internet banking and mobile apps. Each declaration is processed by the institution, which assigns a Unique Identification Number (UIN) and reports the declaration in its quarterly TDS statements to the Income Tax Department.
Before signing the verification, declarants must satisfy themselves that the statements are true and complete. Making a false declaration in Form 121 is punishable under Section 482 of the Act, which carries potential prosecution and financial penalties.
What is a 5-year tax-saving deposit?
A tax-saving deposit is a specialized fixed-term investment designed specifically to qualify for personal tax deductions.
Under Section 123 of the Income-tax Act, 2025 (which corresponds to Section 80C of the repealed 1961 Act), eligible individuals and HUFs can claim a deduction from gross total income for investments in notified deposits, subject to the conditions in Schedule XV and an aggregate statutory ceiling of ₹1,50,000.
However, qualifying products operate under strict regulatory schemes that must be distinguished from ordinary banking deposits.
Eligible Instruments under Schedule XV
Not every five-year deposit qualifies for a deduction. Schedule XV restricts eligibility to specific notified schemes:
Bank Tax-Saver Term Deposits: Issued by scheduled banks under the Bank Term Deposit Scheme, 2006 (notified by the Central Government).
Post Office Time Deposits: Five-year time deposits opened under the National Savings Time Deposit Scheme, 2019 (administered by India Post).
Operational Rules under the Bank Term Deposit Scheme, 2006
For bank tax-saver deposits, the notified scheme establishes clear operational boundaries:
Strict Five-Year Lock-In: The deposit must have a maturity period of not less than five years.
No Premature Encashment: Under the terms of the 2006 scheme, the deposit cannot be encashed before the expiry of five years from the date of receipt, except in the event of the demise of the depositor.
No Pledging or Loan Facilities: The 2006 scheme explicitly prohibits pledging the term deposit certificate to secure a loan or advance, and banks cannot sanction overdraft facilities against it.
Joint Account Rules: When a deposit is held jointly by two adults, the deduction under Section 123 is available only to the first holder named in the certificate.
Post Office Five-Year Time Deposits (POTD)
Five-year Post Office Time Deposits operate under a different statutory framework under the Government Savings Promotion Act.
Unlike bank tax-saver deposits, the Post Office Time Deposit scheme contains specific provisions that permit premature closure after specified holding durations (such as after four years, subject to savings account interest adjustments).
However, closing a deposit prematurely affects statutory compliance and can trigger tax consequences if a deduction was previously claimed under Section 123.
Furthermore, while bank deposits are insured up to ₹5 lakh per depositor by the Deposit Insurance and Credit Guarantee Corporation (DICGC), Post Office deposits are backed directly by the sovereign credit of the Central Government.

The tax regime choice: why tax-saver FDs require verification
The most critical factor when considering a five-year tax-saving deposit today is your choice between personal income tax regimes.
Parliament established the New Tax Regime as the default direct tax framework under the Income-tax Act, 2025. While the new regime features wider income slabs and lower baseline rates, it disallows most personal deductions.
Under the Default New Tax Regime: Deductions under Section 123 (and general Chapter VIII deductions) are not permitted. If you file under the new regime, depositing money into a five-year tax-saving FD provides zero tax relief. You lock away capital for five years without reducing your taxable income.
Under the Optional Old Tax Regime: Section 123 deductions remain available up to the statutory limit of ₹1,50,000 across eligible instruments (such as EPF, PPF, qualifying life insurance, ELSS, and notified five-year term deposits).
Because individual circumstances vary, taxpayers should compare their total tax liability under both regimes based on their actual income, standard deductions, and eligible investments.
The availability of a ₹1,50,000 deduction does not, by itself, determine which tax regime yields a lower overall tax liability.
Is the interest on a 5-year tax-saving FD tax-free?
No. This is a persistent misconception among retail depositors.
A tax-saving deposit provides an upfront deduction on the principal invested, not on the interest earned.
The amount you invest (up to ₹1,50,000) is deducted from your gross taxable income for that tax year under the old tax regime.
Every rupee of interest generated by that deposit across its five-year tenure is fully taxable.
The interest earned each year is classified under Income from Other Sources and taxed at your applicable personal slab rate under Section 393. If the annual interest paid by the bank exceeds ₹50,000 (or ₹1,00,000 for senior citizens), the bank will deduct 10% TDS, exactly as it does on a regular fixed deposit.
Illustrative Post-Tax Return
If an investor in the 30% marginal slab deposits capital into a five-year tax-saving bank deposit paying a 7.00% card rate:
The gross nominal interest rate is 7.00%.
Tax at 30% plus 4% cess amounts to an effective rate of 31.2% on the interest.
The illustrative post-tax return on the deposit is 7.00% x (1 – 0.312) = 4.82%.
While the initial deduction under Section 123 delivers a one-time tax saving in the year of deposit, the ongoing interest return remains subject to annual direct tax erosion.
Regular FD vs tax-saving FD: comparison
To see how operational parameters differ between ordinary fixed deposits and dedicated tax-saving deposits, examine the comparison below:
| Dimension | Regular Bank Fixed Deposit | Notified 5-Year Bank Tax-Saver FD | 5-Year Post Office Time Deposit |
|---|---|---|---|
| Permitted Tenures | 7 days to 10 years (flexible) | Exactly 5 years | Exactly 5 years |
| Principal Deduction | Nil (no deduction under any regime) | Up to ₹1,50,000 under Section 123 (Old Regime only) | Up to ₹1,50,000 under Section 123 (Old Regime only) |
| Interest Taxation | Taxed at personal slab rate | Taxed at personal slab rate | Taxed at personal slab rate |
| Section 393 TDS Threshold | ₹50,000 (₹1,00,000 for seniors) | ₹50,000 (₹1,00,000 for seniors) | ₹50,000 (₹1,00,000 for seniors) |
| Premature Closure Rules | Permitted subject to issuer terms | Prohibited during 5-year lock-in (except death) | Permitted under scheme rules with rate adjustments |
| Loan or Pledging Facility | Available up to 90%–95% of value | Prohibited under 2006 Scheme | Regulated under Post Office rules |
| Safety Backing | Insured up to ₹5 lakh by DICGC | Insured up to ₹5 lakh by DICGC | Backed by Central Government |

Evaluating your options
Deciding whether to use a five-year tax-saving deposit involves balancing liquidity, returns, and tax regulations:
A tax-saving deposit may not align if: You file under the default New Tax Regime, you may need emergency access to your capital within the next five years, or you require borrowing flexibility through loan-against-deposit facilities.
A tax-saving deposit may be worth evaluating if: You have deliberately chosen to file under the Old Tax Regime, you have unutilized deduction room within your Section 123 limit, you seek capital stability backed by banking insurance or sovereign support, and you are prepared to commit capital for five full years.
Review the governing scheme rules, calculate your tax regime position, and verify your liquidity requirements before committing funds.
Common Questions
No. Fixed deposit interest is taxable from the first rupee. The ₹50,000 figure (₹1,00,000 for senior citizens) is strictly a Tax Deducted at Source (TDS) threshold under Section 393 for banking institutions and post offices. If your interest falls below this limit, the bank does not withhold tax, but you must still report the interest in your return and pay applicable tax.
For Tax Year 2026-27, Form No. 121 under Section 393(6) and Rule 211 replaces historical Forms 15G and 15H. It is a single unified self-declaration that allows eligible resident individuals and HUFs with nil estimated tax liability to receive specified interest and other incomes without deduction of TDS.
No. Under the Bank Term Deposit Scheme, 2006, five-year tax-saving bank deposits cannot be encashed prematurely under any circumstances before five years, except in the event of the depositor’s demise.
No. The Bank Term Deposit Scheme, 2006 explicitly bars pledging a tax-saving term deposit to secure loans, advances, or overdraft facilities.
No. Deductions under Section 123 (formerly Section 80C) are not available under the default New Tax Regime in the Income-tax Act, 2025. Tax-saving deposits provide upfront tax relief only for taxpayers who file under the optional Old Tax Regime.
