Two friends, ₹5 lakhs each, the same cautious instinct.

Priya opened a 5-year Post Office Time Deposit.

Arjun opened a 5-year bank FD. Both told themselves they’d made the boring, risk-free choice — the kind of decision you don’t have to think twice about.

Then tax season arrived, and the two of them ended up keeping genuinely different amounts of money.

Not because one rate card was better than the other.

Because of three things almost nobody compares properly: how the interest gets taxed, what happens if a bank runs into trouble, and how easily you can get your money back if life doesn’t go to plan.

The safest-sounding choice and the safest choice aren’t always the same one.

This article walks through all three, with real numbers, so you can make the call for your own money rather than borrow someone else’s rate table.

The Quick Comparison

If you only read one table on this page, make it this one.

Feature	Post Office Time Deposit (5-Year)	Bank Fixed Deposit
Interest rate	7.5% p.a., fixed by the government every quarter (Jul–Sep 2026)	Roughly 6.0%–8.4% p.a. depending on the bank, as of September 2026
Senior citizen benefit	None on the standard TD	Usually +0.25% to +0.75% p.a. over the regular rate
Tax on interest	Fully taxable at your income tax slab	Fully taxable at your income tax slab
TDS	Never deducted — you self-declare and pay	Deducted at 10% once interest crosses ₹50,000 (₹1,00,000 for senior citizens) in a year
Section 80C (5-year option)	Yes, up to ₹1.5 lakh on the principal	Yes, on a tax-saver FD, up to ₹1.5 lakh
Safety net	Sovereign guarantee — backed by the Government of India, no upper limit	DICGC insurance up to ₹5 lakh per depositor per bank (principal + interest combined)
Premature exit (5-year option)	Not allowed before 4 years, under any circumstances	Usually allowed anytime, with a 0.5%–1% rate cut
Compounding	Quarterly for rate-setting; interest paid out annually	Usually quarterly, reinvested until maturity

What a Post Office Time Deposit Actually Pays You Today

The Post Office runs four Time Deposit tenures — 1, 2, 3 and 5 years — and the government resets all four rates every quarter, using a formula tied to government bond yields rather than each post office deciding for itself.

For the July–September 2026 quarter, the ladder looks like this: 6.9% for 1 year, 7.0% for 2 years, 7.1% for 3 years, and 7.5% for 5 years.

You can see the full current breakdown and how these rates have moved since 2016 in our Post Office interest rates guide.

Only the 5-year option gets you the Section 80C deduction. The 1, 2 and 3-year options are purely for the interest rate — no tax break on the principal.

What a Bank FD Actually Pays You Today

Here’s the part most comparison articles gloss over: A Post Office TD has exactly one rate per tenure, set by the government.

A bank FD does not — every bank sets its own, and they can differ by more than two full percentage points on the very same 5-year tenure.

As of September 2026, India’s largest bank, SBI, pays 6.05% p.a. for the general public and 7.05% p.a. for senior citizens on a 5-to-10-year deposit. Several private banks sit in a similar 6.0%–7.5% band.

Small finance banks, on the other hand, often pay noticeably more — Suryoday Small Finance Bank, for instance, has offered 8.25% p.a. on its 5-year FD.

A bigger, better-known bank isn’t automatically paying you more. It’s usually paying you less — that’s part of what “big and stable” costs you.

That gap is not an accident, and it’s the first clue to where this comparison is actually headed.

The Number Most People Get Wrong: How Much FD Interest Is Actually TDS-Free

Search this exact comparison on Google and you’ll likely see ₹40,000 quoted as the TDS-free limit on FD interest.

That number is outdated.

Budget 2025 raised the Section 194A threshold, effective 1 April 2025: banks now deduct TDS only once your interest from that bank crosses ₹50,000 a year for the general public, and ₹1,00,000 a year for senior citizens.

But here’s the detail that actually matters for this comparison: that threshold only governs when a bank deducts TDS.

It says nothing about whether the interest is taxable — it always is, per your slab, regardless of TDS.

Myth vs Reality

Myth: “Post Office TD interest has no TDS, so it must be tax-free.”

Reality: Post Office deposits never deduct TDS — not at ₹50,000, not at ₹5 lakhs, not ever.

But you still owe tax on every rupee of that interest, self-declared under “Income from Other Sources” in your return.

No TDS just means nobody’s collecting it for you in advance — you have to remember to.

No TDS is not the same as no tax. It just means nobody’s reminding you until the tax return does.

With a bank FD, the reminder is automatic — sometimes painfully so.

If you’re not actually liable to pay tax (say your total income is below the basic exemption limit), you can stop the bank from deducting TDS in the first place by submitting Form 15G (under 60) or Form 15H (60 and above) at the start of the financial year.

What Happens If the Bank Fails? The ₹5 Lakh Question

This is the one most people genuinely don’t think about — until they need to.

Every bank FD in India is insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC), but only up to ₹5 lakhs per depositor, per bank — and that ₹5 lakhs covers everything you hold at that bank combined: savings account, recurring deposit, and every FD, added together. It is not ₹5 lakhs per FD.

A Post Office Time Deposit has no such ceiling. It carries a sovereign guarantee — the full backing of the Government of India — on any amount, ₹5 lakh or ₹50 lakhs.

Myth vs Reality

Myth: “A bank FD and a Post Office TD are equally safe — both are practically government-backed.”

Reality: Only the Post Office TD carries an uncapped sovereign guarantee. A bank FD is insured, not guaranteed — and only up to ₹5 lakh total per bank.

This is exactly why financially cautious depositors with large sums split their money across several banks — it’s damage control for a cap most people don’t realise exists until it’s explained to them.

If most of your fixed-income money sits in one bank and comfortably exceeds ₹5 lakhs, that’s worth a second look — either spread it across banks, or let a Post Office TD absorb the amount above the insured limit.

Can You Actually Get Your Money Out Early?

Rate and safety get all the attention. Liquidity is where the Post Office option quietly surprises people.

Since a Department of Posts rule change that took effect on 10 November 2023, a 5-year Post Office TD cannot be closed before completing 4 full years — under any circumstances. Not with a penalty, not at a reduced rate. It simply cannot be withdrawn.

The 1, 2 and 3-year options are more forgiving: no withdrawal before 6 months; between 6 months and 1 year you earn only the Post Office savings rate; after 1 year, you earn the rate for completed years minus 2%.

A bank FD, by contrast, can almost always be closed early — usually online, in minutes — for a rate cut of roughly 0.5% to 1%. You lose some interest. You don’t lose access.

A 5-year commitment should feel like a plan, not a trap. Check the exit door before you walk through the entrance.

So what does this mean for you?

If there’s any real chance you’ll need this money in year 2 or 3 — a child’s admission, a medical situation, a job changes — a 5-year Post Office TD is a considerably harder commitment than a 5-year bank FD, even though both are marketed as “5-year fixed deposits.”

Senior Citizens: Where the Math Tips

For most senior citizens, a standard Post Office TD is not actually the best government-backed option — the comparison itself is slightly the wrong one.

Banks add 0.25%–0.75% for senior citizens on an FD. The standard Post Office TD adds nothing extra.

But the Senior Citizen Savings Scheme (SCSS), a separate Post Office product exclusively for those 60 and above, currently pays 8.2% p.a. with quarterly pay-outs — comfortably ahead of most bank FD senior citizen rates, while still carrying the sovereign guarantee.

If you’re comparing options specifically as a senior citizen, put SCSS in the running before you decide between a Post Office TD and a bank FD.

The Section 80C Angle

Both instruments offer a 5-year, lock-in version that qualifies for a Section 80C deduction of up to ₹1.5 lakh a year — the Post Office 5-year TD, and a bank’s tax-saver FD.

The deduction applies only to the amount you deposit, not to the interest you earn. The interest on both is fully taxable, exactly as it would be on any other TD or FD.

This is one of the more common mix-ups: people assume an 80C-eligible deposit means tax-free interest too. It doesn’t.

Real Numbers: ₹5 Lakh, 5 Years, Two Products

Illustrative only, using each product’s actual pay-out convention — Post Office TD interest is paid out annually rather than compounded within the deposit, while a bank FD in cumulative mode compounds quarterly and pays at maturity.

Option	Total interest over 5 years	Post-tax interest (20% slab)	Post-tax interest (30% slab)
Post Office TD at 7.5%	₹1,87,500	₹1,50,000	₹1,31,250
SBI FD, general public, 6.05%	₹1,75,088	₹1,40,070	₹1,22,562
SBI FD, senior citizen, 7.05%	₹2,09,129	₹1,67,303	₹1,46,390
Small finance bank FD at 8.25%	₹2,52,132	₹2,01,706	₹1,76,492

Notice what this actually shows: at today’s rates, the Post Office TD beats SBI’s own general-public FD rate, loses to SBI’s senior citizen rate, and loses more clearly to a higher-paying small finance bank.

There’s no single winner — there’s a winner for your specific bank, your specific slab, and your specific need for safety versus yield.

These figures are illustrative, based on the rates and slabs stated above as of September 2026; actual bank FD rates change frequently and vary by bank, so treat this as a way to compare methods, not a guarantee of what you’ll earn.

So Which Should You Actually Pick?

There’s no universal right answer here — only a right answer for your situation. A quick way to think about it:

• Large sum, safety is the priority — a Post Office TD’s uncapped sovereign guarantee beats the ₹5 lakh DICGC ceiling on a bank FD.
• You’re a senior citizen — check SCSS first; if you still prefer a TD-style product, compare a bank’s senior citizen FD rate against the standard Post Office TD rate before deciding.
• You might need the money in 2–3 years — lean toward a bank FD, or a shorter Post Office TD tenure; avoid locking into a 5-year Post Office TD you can’t touch before year 4.
• You’re chasing the highest possible rate — a small finance bank FD often wins on headline rate, but keep the ₹5 lakh DICGC cap in mind and consider splitting larger amounts across banks.
• You want to avoid TDS paperwork entirely — a Post Office TD never deducts TDS, though you still owe the tax; a bank FD with Form 15G/15H achieves a similar result if you’re genuinely not liable.

Where a Financial Planner Fits In

None of this is a call for picking a side. Post Office TDs and bank FDs both belong in a well-built fixed-income portfolio — often both at once, for different amounts and different purposes.

What actually moves the needle is matching the product to your slab, your time horizon, and how much of your money is sitting exposed above ₹5 lakhs in a single bank.

That’s a five-minute conversation for someone who’s mapped it before, and a surprisingly easy thing to get wrong on your own.

Frequently Asked Questions

Q1. Is Post Office FD better than bank FD?

It depends on what you’re optimising for. Post Office TD wins on safety (uncapped sovereign guarantee) and, at today’s rates, sometimes on yield too. A bank FD wins on flexibility, senior citizen top-ups, and easier premature exit. Neither is universally “better” — see the decision checklist above.

Q2. Which Post Office scheme is best for tax saving?

For a straightforward 80C deduction with a fixed rate, the 5-year Post Office Time Deposit works well. For senior citizens specifically, the Senior Citizen Savings Scheme (SCSS) is usually the stronger 80C-eligible option, since it also pays a higher rate.

Q3. Is Post Office FD interest tax-free?

No. Post Office TD interest is fully taxable at your income tax slab, exactly like a bank FD. The only difference is that the Post Office never deducts TDS on it — you’re still required to declare and pay the tax yourself.

Q4. Can I double my money in 5 years in the Post Office?

Not through a 5-year Time Deposit at current rates — 7.5% p.a. over 5 years grows ₹5 lakhs to roughly ₹6.87 lakh, not ₹10 lakh. Kisan Vikas Patra is the Post Office product built specifically to double your money, and at its current 7.5% rate it takes 115 months (about 9 years 7 months), not 5 years.

Q5. Which bank is currently giving the highest FD interest rate?

This changes often and varies by bank, so always check current rates before investing. As of September 2026, several small finance banks have offered 5-year FD rates above 8%, well ahead of large public sector banks — but remember the trade-off: DICGC insurance still caps at ₹5 lakhs per depositor per bank, regardless of how small or large the bank is.

Q6. What happens if I withdraw my Post Office TD before maturity?

For a 5-year TD, nothing — it cannot be withdrawn before 4 years under the current rules. For 1, 2 and 3-year TDs, withdrawing after 6 months but before 1 year gets you only the Post Office savings rate; withdrawing after 1 year gets you the rate for completed years, minus 2%.

Q7. Is a Post Office FD insured like a bank FD?

No — and that’s actually to its advantage. A bank FD is insured by DICGC up to ₹5 lakhs per depositor per bank. A Post Office TD isn’t “insured” in that sense; it carries a direct sovereign guarantee from the Government of India, with no upper limit.

Q8. Which FD is best for tax saving — Post Office or bank?

Both the 5-year Post Office TD and a bank tax-saver FD offer an identical ₹1.5 lakh Section 80C deduction on the amount deposited. The deciding factor usually isn’t the tax benefit — it’s the interest rate and the safety net, both covered earlier in this article.
