TDS on FD Interest: How to Avoid Being Over-Taxed on Your Fixed Deposits

Every year, thousands of Indians open a fixed deposit, see interest credited to their account, and then get confused when the bank has quietly deducted a chunk of it as TDS before the money even reaches them. Some assume this deduction is the final tax they owe. Others assume it is unfair and try to dodge it by splitting deposits across banks. Both assumptions can cost you money if you get them wrong.

This post explains exactly how TDS on FD interest works, when it applies, and the legitimate ways to reduce or avoid being over-taxed on your fixed deposit income.

What is TDS on FD interest? #

TDS (Tax Deducted at Source) on fixed deposits means the bank or post office deducts a portion of your interest income and deposits it directly with the Income Tax Department, before crediting the remaining interest to you. It is not an extra tax on top of your normal liability; it is an advance collection of the tax you would eventually owe on that interest anyway.

The confusion usually comes from one fact: TDS is deducted at a flat rate regardless of your actual income tax slab, while your real tax liability on FD interest depends on your total taxable income for the year. This mismatch is exactly where people end up overpaying, or underpaying and getting a notice later.

How TDS on FD interest is calculated #

Banks are required to deduct TDS on FD interest under Section 194A of the Income Tax Act, based on these rules for FY 2026-27:

• Threshold for regular customers: TDS applies once interest from a single bank exceeds ₹40,000 in a financial year.
• Threshold for senior citizens: the limit is higher, at ₹50,000 in a financial year.
• TDS rate: 10% if you have provided your PAN to the bank.
• TDS rate without PAN: 20%, a steep penalty for not linking PAN, so always ensure your PAN is updated with your bank.
• Threshold is per bank, not overall. If you hold FDs in three different banks and earn ₹35,000 interest in each, no single bank crosses the ₹40,000 threshold, so no TDS gets deducted anywhere, even though your total interest income for the year is ₹1,05,000.

That last point is important and widely misunderstood, and we will come back to it in the myths section below.

Real example with Indian numbers #

Suresh, a 35-year-old software professional in Hyderabad, has a fixed deposit of ₹10,00,000 earning 7% annual interest, which comes to ₹70,000 in interest for the year.

Since ₹70,000 crosses the ₹40,000 threshold, the bank deducts TDS at 10%:

• TDS deducted: ₹70,000 × 10% = ₹7,000
• Amount credited to Suresh after TDS: ₹63,000

Now here is where it gets interesting. Suresh falls in the 20% tax slab (after accounting for his other income), so his actual tax liability on this ₹70,000 interest is:

• Tax owed on interest: ₹70,000 × 20% = ₹14,000
• TDS already deducted: ₹7,000
• Additional tax due while filing his return: ₹14,000 − ₹7,000 = ₹7,000

If instead Suresh had no other taxable income and fell below the basic exemption limit, his actual tax liability on that interest could be zero. In that case, the ₹7,000 TDS deducted by the bank would be fully refundable, but only if he files an income tax return to claim it back. Run your own FD amount and rate through the TDS calculator to see the exact deduction and compare it against what you would actually owe based on your slab.

Why TDS often does not match your real tax liability #

The bank deducting a flat 10% has no idea what tax bracket you fall into. This creates two scenarios:

1. You are in a higher slab (20% or 30%): TDS covers only part of your liability, and you owe more tax while filing your return.
2. You are in a lower slab or below the taxable limit: TDS over-collects, and you need to claim a refund by filing your income tax return, since the bank has no way of adjusting for this automatically.

Either way, TDS is not the final word on your FD tax liability. Your actual tax on interest income is determined by your total income and applicable slab under the income tax calculator, not by the flat rate the bank applies.

Legal ways to avoid or reduce TDS on FD interest #

Submit Form 15G or Form 15H. If your total income is below the basic taxable limit, you can submit Form 15G (for individuals below 60) or Form 15H (for senior citizens) to your bank at the start of the financial year, declaring that your income does not attract tax. This instructs the bank not to deduct TDS at all, rather than deducting it and forcing you to claim a refund later.

Spread deposits across banks thoughtfully, within reason. If your total interest income across all banks genuinely stays under the taxable threshold once combined with your other income, holding FDs in separate banks below the per-bank ₹40,000 threshold can avoid upfront TDS deduction and the resulting cash flow hit, since you are not out of pocket until you file your return.

Time your FD maturity across financial years. If a large FD is about to mature and push your interest income over the threshold in one financial year, check whether restructuring the tenure so interest gets credited across two financial years instead keeps you under the annual threshold in each year.

Use the tax-saving FD wisely, but understand its limits. A 5-year tax-saving FD gives you a Section 80C deduction on the principal invested, but the interest earned on it is still fully taxable and subject to the same TDS rules as any other FD. Do not confuse "tax-saving" with "tax-free interest".

Claim TDS credit correctly at tax filing time. Whatever TDS gets deducted shows up in your Form 26AS and the Annual Information Statement (AIS). Always cross-check these against your bank interest certificates before filing, since TDS credit only reduces your tax if you correctly report the interest income and claim the deduction in your return.

Common myths and mistakes #

Myth: If TDS was not deducted, the interest is tax-free. This is false and one of the most expensive misunderstandings in Indian personal finance. Interest income is taxable at your slab rate regardless of whether TDS was deducted. Splitting deposits across banks avoids TDS deduction, not your actual tax liability, and you are legally required to report and pay tax on the full interest earned across all your FDs.

Mistake: Not filing Form 15G/15H even when eligible. Many people eligible for zero TDS never submit these forms, and end up going through the refund process every year unnecessarily, tying up cash for months.

Mistake: Forgetting to report FD interest because "the bank already deducted tax". The bank deducting TDS does not remove your obligation to report the gross interest income in your income tax return. Missing this can trigger a mismatch notice from the tax department, since your bank reports the interest to the department regardless.

Mistake: Submitting Form 15G/15H when not actually eligible. Declaring income below the taxable limit when it is not true is a false declaration with penal consequences. Only submit these forms if your total income genuinely falls below the basic exemption limit for the year.

Tips for managing FD taxation better #

• Check the interest certificate from each bank annually and reconcile it with Form 26AS before filing your return.
• If you hold FDs specifically for tax efficiency, compare the after-tax return against alternatives like debt mutual funds or the PPF calculator, especially if you are in a higher tax slab where FD interest taxation eats significantly into your return.
• Renew Form 15G/15H every financial year; a form submitted last year does not automatically apply to the new year.
• If you are a senior citizen, remember the exemption threshold is higher at ₹50,000 per bank, and there is also a separate deduction available under Section 80TTB for interest income up to ₹50,000, which is worth factoring into your overall income tax calculator planning.
• Keep FD maturity dates staggered rather than bunched, both for liquidity planning and to manage which financial year the interest income falls into.

Frequently asked questions #

At what FD interest amount does TDS get deducted? #

TDS applies once interest income from a single bank exceeds ₹40,000 in a financial year for regular customers, or ₹50,000 for senior citizens. This threshold applies per bank, not across all your FDs combined.

What is the TDS rate on fixed deposit interest? #

The standard TDS rate is 10% if your PAN is linked with the bank. If PAN is not provided or is invalid, banks are required to deduct TDS at a much higher rate of 20%.

Can I avoid TDS on FD interest legally? #

Yes, by submitting Form 15G (if you are below 60 and your income is below the taxable limit) or Form 15H (if you are a senior citizen) to your bank at the start of the financial year. This tells the bank not to deduct TDS, provided your declaration is accurate.

Does TDS mean I do not have to pay any more tax on FD interest? #

No. TDS is only an advance deduction, not your final tax liability. If your applicable tax slab is higher than the TDS rate, you owe additional tax at the time of filing your return. If your slab is lower, you can claim a refund of the excess TDS deducted.

Do I need to report FD interest in my tax return even if no TDS was deducted? #

Yes. All FD interest income is taxable and must be reported in your income tax return regardless of whether TDS was deducted. Splitting deposits across multiple banks to stay under each bank's TDS threshold does not exempt the income from tax, it only avoids upfront deduction at source.

Getting your FD taxation right #

TDS on fixed deposits is often misunderstood as either the full tax you owe or an unfair deduction you can dodge entirely. In reality, it is simply an advance collection mechanism, and your actual liability depends on your total income and slab for the year.

Use the TDS calculator to check exactly how much tax will be deducted on your FD interest before it happens, and plan whether Form 15G/15H, staggered deposits, or an alternative like a tax-saving calculator comparison makes more sense for your situation this financial year.
