How Much Income Tax Do You Pay on FD Interest in India?

Fixed deposits feel safe. You put your money in, the bank promises a fixed rate, and at maturity you get your principal plus interest. No market swings, no sleepless nights. But there's a quiet thief in this picture that many savers overlook: tax. The return you see advertised — say 7.5% — is rarely the return that actually lands in your pocket.

Understanding the tax on FD interest is the difference between thinking you earned 7.5% and realising you actually kept 5.25%. This guide breaks down TDS, the ₹40,000 and ₹50,000 thresholds, and how to calculate your real post-tax yield so you can compare FDs honestly against other options.

How is FD interest taxed in India?

Here's the part that surprises people: interest from a fixed deposit is fully taxable. It gets added to your total income under the head "Income from Other Sources" and is taxed at your applicable income-tax slab rate.

So if you're in the 30% bracket, your FD interest is effectively taxed at 30% (plus cess). If you're in the 5% bracket, it's taxed at 5%. There is no special lower rate for FD interest the way there is for, say, long-term capital gains on equity.

This single fact changes everything. A senior citizen with little other income and a salaried professional in the top bracket can hold the exact same FD at the same rate — and walk away with very different net returns.

Rule of thumb: your FD's real return = advertised rate × (1 − your slab rate). A 7.5% FD for someone in the 30% bracket effectively yields about 5.1% after tax.

Is FD interest taxed every year or only at maturity?

This trips up a lot of people with multi-year FDs. The interest is taxable on an accrual basis every financial year, even if you receive the money only at maturity. So if you have a 5-year cumulative FD, you're expected to declare the interest accrued each year and pay tax on it annually — not wait until year five.

You can choose to report it either on an accrual basis (yearly) or a receipt basis (at maturity), but accrual is cleaner and avoids a huge tax shock in the final year. Whichever you pick, stay consistent.

What is TDS on FD interest and when does the bank deduct it?

TDS stands for Tax Deducted at Source. Banks are required to deduct tax before they pay you the interest, then deposit it with the government on your behalf and report it against your PAN.

Here are the key numbers for FDs held by individuals:

• TDS rate: 10% if your PAN is registered with the bank.
• Without PAN: a much steeper 20%.
• Threshold for non-senior citizens: TDS kicks in only when FD interest from a single bank crosses ₹40,000 in a financial year.
• Threshold for senior citizens (60+): the limit is higher at ₹50,000.

An important nuance: TDS is calculated across all your deposits with the same bank, not per FD. If you have three FDs at the same bank earning ₹15,000 each, that's ₹45,000 total — TDS applies even though no single FD crosses ₹40,000.

TDS is not the final tax

This is the biggest misconception. TDS at 10% does not mean your tax liability is settled at 10%. It's only an advance against your final bill.

• If you're in the 30% slab, the bank cuts 10%, but you still owe the remaining ~20% when you file your return.
• If you're in the 5% slab or have no taxable income, you may have overpaid through TDS and can claim a refund.

To estimate your overall liability across salary, FD interest and other income, run the numbers through an income tax calculator before the financial year ends. It helps you spot whether you'll owe extra or get a refund.

How much tax will I actually pay on FD interest? (Worked examples)

Let's make this concrete with three savers, each holding ₹10 lakh in FDs at 7.5%, earning ₹75,000 in interest for the year.

Example 1: Ramesh, 35, 30% bracket

• Interest earned: ₹75,000
• Bank deducts TDS at 10%: ₹7,500
• Actual tax owed (30% + 4% cess ≈ 31.2%): ₹23,400
• Extra tax to pay at filing: ₹23,400 − ₹7,500 = ₹15,900
• Net interest kept: ₹75,000 − ₹23,400 = ₹51,600 → real yield ≈ 5.16%

Example 2: Priya, 42, 20% bracket

• Interest earned: ₹75,000
• Tax owed (20% + cess ≈ 20.8%): ₹15,600
• Net interest kept: ₹59,400 → real yield ≈ 5.94%

Example 3: Mr. Sharma, 67, senior citizen, low income

If his total income stays below the basic exemption limit, his FD interest may not be taxable at all. Senior citizens also get a deduction under Section 80TTB of up to ₹50,000 on interest from deposits. By submitting Form 15H, he can ask the bank not to deduct TDS in the first place — so his real yield stays close to the full 7.5%.

Same FD, same rate — but the net outcome ranges from 5.16% to 7.5% depending purely on who holds it. That's why comparing the headline rate alone is misleading.

How do I avoid or reduce TDS on FD interest legally?

You can't escape the tax if you're liable, but you can avoid unnecessary TDS and manage cash flow better:

1. Submit Form 15G / 15H: If your total income is below the taxable limit, file Form 15G (under 60) or Form 15H (60+) with your bank at the start of the financial year. The bank then won't deduct TDS.
2. Always register your PAN: This alone keeps TDS at 10% instead of 20%.
3. Use Section 80TTB if you're a senior: Claim up to ₹50,000 deduction on deposit interest.
4. Pay advance tax if you're in a high bracket: Since TDS only covers 10%, set aside the balance and pay advance tax in instalments to avoid interest penalties under Sections 234B/234C.
5. Spread thoughtfully: Splitting FDs across banks can keep each below the TDS threshold — but remember the tax is still owed; you're only deferring the TDS, not the liability.

One thing to avoid: don't split FDs purely to dodge TDS while hiding income. The interest is reported to the tax department through your PAN and shows up in your Annual Information Statement (AIS). Declare everything.

How does post-tax FD return compare to other investments?

Once you account for tax, the picture shifts. For someone in the 30% bracket, a 7.5% FD yielding ~5.1% post-tax struggles to beat inflation. Run your assumed inflation rate through an inflation calculator and you may find your "safe" money is barely holding its purchasing power.

This doesn't make FDs bad — they're brilliant for emergency funds, short-term goals and capital you simply can't afford to risk. But for long-term wealth building, it's worth comparing:

• PPF: interest is fully tax-free, which makes its effective yield far higher for high earners. See how PPF stacks up against NPS for retirement.
• Equity SIPs: taxed more gently on long-term gains. Curious how much you'd need monthly? Try our SIP calculator or read how much SIP it takes to reach ₹1 crore.
• FD laddering: a smart way to manage reinvestment risk while staying in deposits — covered in our FD laddering guide.

To see your FD maturity value before tax, plug your numbers into the FD calculator, then apply your slab rate to estimate the real take-home. For recurring deposits, the RD calculator works the same way — and yes, RD interest is taxed identically to FD interest.

A quick post-tax FD checklist

• Confirm your PAN is registered with every bank holding your FDs.
• Add up interest from all FDs at each bank to check against the ₹40,000 / ₹50,000 threshold.
• Declare FD interest on accrual basis each year, even for cumulative FDs.
• If below the taxable limit, submit Form 15G/15H early in the year.
• If you're a senior, claim the ₹50,000 Section 80TTB deduction.
• If in the 20% or 30% bracket, budget for tax beyond the 10% TDS.
• Compare the post-tax yield — not the headline rate — before locking funds in.

Frequently asked questions

Does TDS at 10% mean my FD interest is only taxed at 10%?

No. TDS is just advance tax collection. Your FD interest is taxed at your full slab rate. If you're in the 30% bracket, you'll owe the difference when you file your return; if you're in a lower bracket or have no taxable income, you can claim a refund.

Is FD interest tax-free for senior citizens?

Not automatically, but senior citizens get a deduction of up to ₹50,000 on deposit interest under Section 80TTB. If total income stays below the exemption limit, they can submit Form 15H so the bank doesn't deduct TDS at all.

Will I pay tax even if the bank didn't deduct TDS?

Yes. If your interest stays under the ₹40,000/₹50,000 threshold, no TDS is deducted — but the income is still taxable. You must add it to your return and pay tax according to your slab. It will appear in your AIS, so don't skip it.

Is the tax treatment the same for tax-saving 5-year FDs?

The interest is taxed exactly the same way — fully at your slab rate. The only difference is that the principal invested (up to ₹1.5 lakh) qualifies for a Section 80C deduction under the old tax regime. The interest earned never becomes tax-free.

How do I estimate my real post-tax FD return quickly?

Multiply the FD rate by (1 minus your slab rate). For example, an 8% FD for someone in the 20% bracket gives roughly 8% × 0.80 = 6.4% post-tax. For a precise figure including cess and other income, use our income tax calculator.

The bottom line

FDs are dependable, but they're not as generous as their headline rates suggest once the taxman takes his share. Understanding the tax on FD interest — how it follows your slab, when TDS applies, and how the ₹40,000/₹50,000 limits work — lets you judge your savings on their real, post-tax merit rather than a number on a poster.
