Fixed‑Deposit Taxation in FY 2025‑26: How TDS, Form 15G/15H, and Tax Slabs Shape Your Returns
Fixed deposits (FDs) remain the most common way Indians lock in savings for a fixed period. While banks advertise attractive rates, the tax treatment can erode the real yield. This article walks through every tax‑related nuance you need to know before you sign a deposit agreement: the 10 % TDS rule, when to file Form 15G/15H, how interest is taxed at the end of the term, the impact of the old versus new tax regimes, and why debt‑fund indexation matters after the 2023 reforms. A step‑by‑step example shows how cumulative tax on accrual versus payout can change your net gain.

| Category | Annual Interest Threshold | TDS Rate |
|---|---|---|
| Non‑senior (under 60) | ₹40 000 | 10 % |
| Senior (60‑80) | ₹50 000 | 10 % |
| Super‑senior (80+) | ₹50 000 | 10 % |
The Income Tax Act mandates that if the interest earned in a calendar year exceeds the above thresholds, the bank must deduct 10 % TDS at source. This deduction is made before the interest is credited to your account. It is not a final tax; you still need to report the interest in your annual return and pay any additional tax based on your slab.
---
| Situation | Form | Eligibility |
|---|---|---|
| Non‑taxable interest (e.g., below ₹40 000 or if you are in the lowest slab) | 15G | Any taxpayer |
| Senior or super‑senior with interest below ₹50 000 | 15H | Age ≥ 60 (or 80 for 15H) |
Submitting Form 15G/15H tells the bank that you expect the interest to be below the TDS threshold or that you are in a tax‑exempt bracket. If you do not submit and the interest exceeds the threshold, the bank will still deduct 10 % TDS. However, if you later find that the interest was below the threshold, you can claim a refund by filing a revised return.
Tip: For long‑term FDs (≥ 5 years), the cumulative interest often exceeds the threshold. In such cases, it is safer to let TDS be deducted and claim the credit later.

FD interest is accrued each year but paid only at maturity. Therefore, the tax is applied when you receive the interest, not when it accrues. Let’s see how this works.
#### Step‑by‑step calculation
| Year | Interest earned | Cumulative interest | Taxable at maturity | TDS (10 %) | Net interest after TDS | Tax payable (30 %) | Net after tax |
|---|---|---|---|---|---|---|---|
| 1 | ₹65 000 | ₹65 000 | ₹65 000 | ₹6 500 | ₹58 500 | ₹19 500 | ₹39 000 |
| 2 | ₹65 000 | ₹1 30 000 | ₹1 30 000 | ₹13 000 | ₹1 17 000 | ₹35 100 | ₹81 900 |
| 3 | ₹65 000 | ₹1 95 000 | ₹1 95 000 | ₹19 500 | ₹1 75 500 | ₹52 650 | ₹122 850 |
| 4 | ₹65 000 | ₹2 60 000 | ₹2 60 000 | ₹26 000 | ₹2 34 000 | ₹70 200 | ₹163 800 |
| 5 | ₹65 000 | ₹3 25 000 | ₹3 25 000 | ₹32 500 | ₹2 92 500 | ₹87 750 | ₹204 750 |
Total interest earned: ₹3 25 000 Total TDS deducted: ₹1 62 500 Total tax payable: ₹3 48 750 Net after tax: ₹1 76 250
#### What does this tell you?

| Regime | Standard Deduction | Tax Slabs (FY 2025‑26) | Impact on FD Interest |
|---|---|---|---|
| Old | ₹50 000 | 5 % up to ₹2.5 L, 20 % up to ₹5 L, 30 % above | If you claim deductions (e.g., HRA, PF), your taxable income may fall into a lower slab, reducing tax on FD interest. |
| New | No standard deduction | 5 % up to ₹3 L, 20 % up to ₹5 L, 30 % above | No deductions; higher marginal tax for the same income, potentially increasing tax on FD interest. |
Example: Suppose your annual income is ₹12 00 000. Under the old regime, after a ₹50 000 standard deduction and ₹1 00 000 from PF, taxable income becomes ₹10 50 000, placing you in the 30 % slab for the amount above ₹5 L. Under the new regime, taxable income is ₹12 00 000, still in the 30 % slab but with no deductions. The difference in tax on ₹3 25 000 FD interest is minimal (₹3 48 750 vs ₹3 48 750), but for higher incomes the new regime can increase tax liability by up to ₹10 000–₹15 000 annually.
Bottom line: If you have significant deductions, the old regime may give you a tax advantage on FD interest. Evaluate your total tax liability before deciding which regime to adopt.

In 2023, the Income Tax Department clarified that debt mutual funds are treated as capital assets for tax purposes. Long‑term capital gains (LTCG) on debt funds held for more than 36 months are taxed at 20 % with indexation. Short‑term gains (≤ 36 months) are taxed at your slab rate.
Why this matters for FDs:
| Instrument | Taxable event | Tax rate | Indexation | Holding period |
|---|---|---|---|---|
| FD | Interest at maturity | Your slab | No | N/A |
| Debt fund | Capital gain | 20 % (LTCG) | Yes | > 36 months |
| Debt fund | Capital gain | Slab rate | No | ≤ 36 months |

| Mistake | Consequence | How to Avoid |
|---|---|---|
| Ignoring the TDS threshold | Unnecessary TDS deduction or missing refund | Check interest amount against ₹40 000/₹50 000 before filing |
| Not filing Form 15G/15H when eligible | Unnecessary TDS | Submit the form if you are in the lowest slab or expect interest below threshold |
| Assuming tax is paid at accrual | Misjudging cash flow | Remember tax is due only at maturity |
| Choosing the new regime without evaluating deductions | Higher tax on FD interest | Compare total tax under both regimes |
| Treating debt fund gains like FD interest | Overpaying tax | Apply indexation for LTCG on debt funds held > 3 years |

| Question | Answer |
|---|---|
| What is the exact TDS rate on FD interest? | 10 % on interest exceeding ₹40 000 (₹50 000 for seniors). |
| Can I avoid TDS by filing Form 15G? | Yes, if your total interest for the year is below the threshold or you are in the lowest slab. |
| Does the FD interest get taxed at the time of accrual? | No, it is taxed when the interest is paid at maturity. |
| How does the new tax regime affect my FD returns? | Without deductions, your marginal tax may increase, raising the tax on FD interest. |
| Is there any benefit to investing in debt funds instead of FDs? | For long‑term holdings (> 3 years), debt funds offer indexation on capital gains, potentially lowering tax compared to FD interest. |
| Do I need to keep any special documents for FD tax? | Keep the deposit receipt, interest statement, and TDS certificate (Form 16A) for audit and filing. |

1. Calculate expected interest and compare it with the TDS threshold. 2. Decide on the tax regime after reviewing your total deductions. 3. Submit Form 15G/15H if eligible to avoid unnecessary TDS. 4. Plan for tax at maturity: Use the example above to estimate net returns. 5. Consider debt funds if you can hold them for > 3 years to benefit from indexation. 6. Keep all documents (deposit slip, interest statement, TDS certificate) in a single folder for filing.

Fixed deposits offer safety and predictable returns, but tax can erode the headline yield. By understanding TDS thresholds, leveraging Form 15G/15H, and comparing the old and new tax regimes, you can optimise your net gain. Remember that debt funds, with their indexation advantage for long‑term holdings, may provide a better after‑tax return if you are comfortable with market risk. Use the tables and example above to run your own numbers and make an informed choice for FY 2025‑26.
