Fixed-deposit interest is taxable in India even when a bank does not deduct tax at source (TDS). TDS is only tax withheld in advance; your final tax depends on your total income, applicable tax regime and eligible deductions. For interest credited or paid from 1 April 2026, the Income Tax Act, 2025 applies. For an interest event before that date, the Income Tax Act, 1961 governs the TDS event, even if the money is paid or the TDS deposited later.

Is FD interest taxable?

Yes. Interest from a fixed deposit (FD) is taxable income. The Income Tax Department’s return materials classify interest from bank, post-office and cooperative-society deposits as interest income in the income-from-other-sources schedule. The fact that a bank did not withhold TDS does not make the interest exempt, and a bank’s TDS deduction does not by itself settle the final tax due.

There are two separate calculations to keep straight:

  • Withholding: whether the bank must deduct TDS, and how much it withholds, under the rules for the relevant interest event.
  • Final tax: the tax due after the interest is included with your other income and the applicable tax rules and eligible deductions are applied.

This distinction is why two people receiving the same FD interest can have different final tax outcomes. Their total income, tax regime, eligible deductions, residence status, age and applicable tax year may differ.

When does the bank deduct TDS on FD interest?

For resident payees, the Income Tax Department’s rate table lists a 10% rate under section 194A for interest other than interest on securities. The department’s current threshold guidance lists a threshold of ₹50,000 for non-senior citizens and ₹1,00,000 for senior citizens for bank time-deposit interest. These are TDS thresholds—not tax-free income limits.

In practical terms, the threshold is relevant to whether the bank withholds TDS. It does not determine whether interest must be reported or taxed in your return. A depositor can have interest below the relevant threshold and still have taxable interest income. Equally, TDS withheld is not necessarily equal to the final tax on that income.

The threshold guidance is year-sensitive. The figures above are the amounts listed in the Income Tax Department’s threshold guidance accessed in 2026. The department’s section 194A page has older threshold wording in places, so do not rely on an older figure without checking the current official threshold guidance for the relevant year. This distinction matters particularly around a change in tax law: the threshold is a withholding rule, while the governing Act depends on when the interest event occurs.

How banks aggregate deposits

Do not assess the threshold by looking only at one FD or one branch. For a bank using core banking solutions, interest is generally aggregated at the bank level rather than branch by branch. Several deposits held with the same bank may therefore matter together when the bank determines whether the threshold is crossed. The department’s guidance ties this aggregation point to banks using core banking solutions; it should not be generalized into a claim about every institution or every arrangement.

Resident and non-resident treatment

The 10% rate and threshold explanation here is for resident payees and bank time-deposit interest. Non-resident deposits can be subject to different treatment, and the general resident rate table is not enough to determine the tax or withholding for a non-resident. Missing or invalid PAN, special exemptions and other individual facts can also affect the applicable treatment. If any of those circumstances applies, use the rules relevant to that status and deposit rather than applying the resident explanation mechanically.

How to work out the tax on your FD interest

Work through the income reporting and tax calculation in sequence. The bank’s TDS statement is useful evidence, but it is not a substitute for identifying all interest and calculating your own liability.

  1. Collect the year’s interest information. Identify interest from all relevant FDs, including deposits at different branches or banks, and note the dates on which interest was credited or paid. Compare the figures with your bank records and tax records.
  2. Report the interest in the return. Include it under the relevant interest-income reporting category. The Income Tax Department’s return materials separately identify interest from bank, post-office and cooperative-society deposits in the income-from-other-sources schedule.
  3. Combine it with your other income. FD interest is part of the overall income picture. The TDS threshold is not an amount you can subtract from income as a tax-free allowance.
  4. Apply the rules for your tax regime and eligible deductions. The final result depends on your applicable regime and circumstances. For example, an eligible resident senior citizen may be able to claim a section 80TTB deduction, subject to the applicable eligibility and regime restrictions.
  5. Reconcile tax withheld against tax due. Compare TDS reflected in your tax records with your bank records, report the income correctly and account for the TDS credit when determining the remaining tax due or any excess withholding.

The department’s published TDS rate is therefore not a personal tax estimate. A 10% withholding rate does not mean every depositor’s final tax rate is 10%; nor does the absence of withholding mean there is no tax to pay. The return calculation uses total income and applicable tax rules, while TDS is a credit for tax already withheld.

Senior citizens and section 80TTB

For assessment year 2026–27, the Income Tax Department’s guidance says eligible resident senior citizens can claim a deduction of up to ₹50,000 under section 80TTB for qualifying interest from deposits with banks, post offices or cooperative banks; FD interest is included. This is a conditional deduction, not an automatic payment or a change to the TDS threshold. Return validation guidance also restricts the deduction based on the selected tax regime. Check that you meet the conditions and that your chosen regime permits the claim before including it.

Which tax law applies to interest around 1 April 2026?

The transition date is determined by the TDS event, not simply by when you withdraw the FD or receive the money in your account. The Income Tax Department’s transition guidance says TDS liability arises at the earlier of interest credit or payment. That earlier date determines which Act governs the event.

Interest event Governing law for the TDS event What to keep in mind
Interest credited or paid before 1 April 2026 Income Tax Act, 1961 The 1961 Act governs that TDS event even if payment or TDS deposit happens later.
Interest credited or paid from 1 April 2026 onward Income Tax Act, 2025 The 2025 Act applies to tax-year events beginning on or after this date; provisions have been consolidated or renumbered.

For example, if interest is credited on 31 March 2026 and paid in April, the event is governed by the 1961 Act because the credit came first. For a new interest event on or after 1 April 2026, use the 2025 Act’s terminology and provisions. The department says the rates and monetary thresholds were retained under the new Act, but provision references were consolidated or renumbered. Do not carry an old section number into a post-transition explanation as though the numbering had not changed.

The department’s resident rate table identifies 10% under section 194A, while its transition guidance says rates were retained under the 2025 Act. These statements concern the rate and the statutory transition respectively; they do not make section 194A the correct new-Act section reference for every event from April 2026 onward. Use the applicable official guidance for the tax year and event date.

Can you avoid TDS with a declaration?

The declaration form depends on the tax year. For tax years beginning 1 April 2026 onward, eligible residents who estimate that their tax liability for the year will be nil can furnish Form 121 to request non-deduction. The department says Form 121 retains the earlier Forms 15G and 15H eligibility criteria. For relevant prior years, Forms 15G and 15H remain the applicable terminology.

A declaration changes withholding; it does not convert taxable FD interest into exempt income. It is a claim that you meet the eligibility conditions, including the relevant nil estimated tax liability condition described by the department. Do not submit the form merely because your interest is below a TDS threshold or because you would prefer the bank not to withhold tax. The form and the taxability of the income answer different questions.

A lower- or nil-withholding certificate is a separate route from Form 121. Do not treat it as another name for the declaration. Which route is available depends on the taxpayer’s circumstances and the applicable rules.

If TDS has already been deducted

If a bank has withheld TDS, compare the interest and TDS shown in your tax records with your own bank statements and deposit information. Include the interest in the return and claim the withholding credit accurately, using records that agree with the actual deposits and tax reporting. Do not assume that submitting Form 121 after a deduction automatically reverses tax already withheld. The correction or reconciliation needed for a mismatch depends on the records and filing circumstances.

Why can two FD holders have different outcomes?

When comparing withholding or final tax, check the factors that can change the result rather than comparing the headline interest amount alone.

Factor Why it matters
Interest-event date and tax year The earlier of credit or payment determines whether the 1961 Act or the 2025 Act governs the TDS event.
Resident or non-resident status The resident rate and threshold discussion does not establish the treatment for non-resident deposits.
Age and senior-citizen status The department lists different bank time-deposit TDS thresholds for senior and non-senior citizens; an eligible senior citizen may also qualify for a separate section 80TTB deduction.
Aggregate interest at the bank When the bank uses core banking solutions, interest is generally considered at bank level, not branch by branch.
Total income, tax regime and eligible deductions These determine the final tax calculation, not the TDS threshold alone.
TDS already withheld Withholding is reconciled against the final tax due; it is not itself the final liability.

A useful way to avoid errors is to keep the withholding question and return question separate. Ask first which rules apply to the event and whether the bank was required to deduct. Then determine all taxable interest, report it with other income, apply the correct regime and eligible deductions, and reconcile the tax already credited.
