Post Office Time Deposits.
A Fixed Deposit With a Sovereign Guarantee. 80C on the 5-Year.
Published as on 29 June 2026
A Post Office Time Deposit (POTD), also called the National Savings Time Deposit, is the post-office equivalent of a bank FD — run by the Government of India through India Post. Lock a lump sum (min ₹1,000, multiples of ₹100, no upper limit) for 1, 2, 3 or 5 years at government-set, quarterly-revised rates: 6.9% to 7.5% for the Jan-Mar 2026 quarter. Backed by an unlimited sovereign guarantee, not DICGC insurance. Interest is calculated quarterly but paid annually. Only the 5-year tenure qualifies for a Section 80C deduction (Old Regime). A capital-preservation tool for conservative savers — designed for certainty, not for beating inflation.

Executive Summary · 6 Findings
POTD answers a narrow question well: how do I park money I'll need on a fixed future date, with absolute certainty about both the amount and its safety? You deposit a lump sum, choose a 1-5 year lock-in, earn a government-fixed rate, and collect principal plus interest at maturity — protected by the full sovereign guarantee of the Government of India, not the ₹5 lakh DICGC cap that limits bank FDs.
Covers how POTD works and current rates, quarterly-compounded interest paid annually, POTD vs bank FD, the 5-year 80C deduction (Old Regime only) with its caveats, premature withdrawal rules and penalties, taxation at slab with no TDS, the right place for POTD in a savings plan, and seven retail questions on opening online, nomination, NRI rules, loans and maturity.
Key Findings
Government FD: 6.9-7.5% across four tenures.
POTD is a fixed-tenure scheme via India Post. Jan-Mar 2026 rates: 1-yr 6.9%, 2-yr 7.0%, 3-yr 7.1%, 5-yr 7.5%. Rates are government-set and revised quarterly, but unchanged since April 2024. Minimum ₹1,000, then multiples of ₹100, no upper limit. Your rate is locked at opening for the full tenure.
Sovereign guarantee — no ₹5 lakh ceiling.
The biggest distinction from a bank FD is the backing, not the rate. POTD carries the unlimited sovereign guarantee of the Government of India. Bank FDs are insured by DICGC only up to ₹5 lakh per depositor per bank. For deposits above ₹5 lakh, POTD offers wider protection; under ₹5 lakh, both are effectively safe.
Interest: quarterly compounded, paid annually.
Interest is calculated every quarter but credited once a year to your linked Post Office Savings Account. ₹1,00,000 in a 5-year POTD at 7.5% earns ₹7,714 after one year (effective >7.5% due to quarterly compounding). No auto-reinvestment — to compound, you must manually redeploy the interest.
5-year tenure gets 80C — interest still taxable.
Only the 5-year POTD qualifies for a Section 80C deduction up to ₹1.5 lakh, and only under the Old Tax Regime. The deduction applies to the investment, never to the interest. A ₹12L earner in the Old Regime can save ~₹30,000 in tax. New Regime users (default since FY 2023-24) get zero 80C benefit.
Premature exit: locked 6 months, then penalised.
No withdrawal in the first 6 months. After that, completed years earn the TD rate minus 2%; any incomplete period earns only the Post Office Savings Account rate (~4%). The penalty is both the 2% cut and the opportunity cost of not having chosen a shorter tenure. If there's real chance you'll need the money in 2-3 years, pick a shorter POTD.
Taxed at slab, no TDS — and won't beat inflation.
Interest is added to income and taxed at your slab rate; unlike bank FDs, POTD deducts no TDS — but you must still declare it. At 7.5%, after a 30% slab (~5.25% post-tax) and 6-7% inflation, real returns are near zero. POTD is a capital-preservation tool for 1-5 year goals, not a wealth builder.

Rates set by the Government of India and revised each quarter; unchanged since April 2024. Once you open a POTD, your rate is fixed for the full tenure regardless of later quarterly revisions — protection if rates fall, reinvestment risk if they rise.
The Opening · Page 3
The Opening
A Post Office Time Deposit is a fixed-tenure savings scheme run by the Government of India through post offices across the country. You deposit a lump sum (minimum ₹1,000, then multiples of ₹100, no upper limit), choose a 1, 2, 3 or 5-year lock-in, earn a government-set rate, and get your money back with accumulated interest at maturity. Think of it as a government-run safe deposit box that grows at a fixed, predictable rate — and unlike a savings account, your money is locked for the chosen term in exchange for higher interest.
"Government backing means safety, not superior returns. POTD rates (7.5% max) are only slightly higher than the FDs of major banks because the government doesn't need to offer high rates to attract deposits — the sovereign guarantee itself is the selling point. A government bond is safer than a corporate bond, but the corporate bond pays more precisely because it carries more risk."
The Safety-Not-Yield Frame
The mathematics. Interest is calculated quarterly and paid annually. ₹1,00,000 in a 5-year POTD at 7.5% compounds quarterly to ₹1,07,714 after one year — ₹7,714 of interest, slightly above simple 7.5%. The interest credits to your linked Post Office Savings Account; it does not auto-reinvest, so compounding beyond year one requires you to redeploy it manually.
The 2026 context. Rates have been unchanged since April 2024. Because the New Tax Regime became the default from FY 2023-24, most young professionals and new taxpayers are automatically in the New Regime — meaning the 5-year POTD's Section 80C benefit is irrelevant to them unless they have explicitly opted back into the Old Regime. For seniors, the Senior Citizens Savings Scheme (SCSS) at 8.2% is a better small-savings option than POTD.

How POTD Works, the Rates, Interest Mechanics, and vs the Bank FD
The four tenures and their government-set quarterly rates, how interest is compounded quarterly but paid annually, and the real difference between a Post Office Time Deposit and a bank fixed deposit — sovereign guarantee versus the ₹5 lakh DICGC cap.

How It Works
| Step | Detail |
|---|---|
| 1. Deposit | Lump sum, min ₹1,000, multiples of ₹100, no cap |
| 2. Choose tenure | 1, 2, 3 or 5 years |
| 3. Earn | Fixed govt rate, locked at opening |
| 4. Maturity | Principal + interest returned |
Current Rates (Jan-Mar 2026)
| Tenure | Rate |
|---|---|
| 1 year | 6.9% |
| 2 years | 7.0% |
| 3 years | 7.1% |
| 5 years | 7.5% |
Interest Mechanics
Quarterly Compounded, Paid Annually
₹1,00,000 in a 5-yr POTD at 7.5%: compounds quarterly to ₹1,07,714 after one year → ₹7,714 interest, above the simple 7.5%.
Interest credits annually to your linked Post Office Savings Account. It does not auto-reinvest — set a standing instruction or redeploy manually to keep compounding.
Worked Example
Priya, Pune, saving for a wedding in 3 years. She picks the 3-year POTD at 7.1% over a savings account (4%) or bank FD (~7%): the date is fixed, the rate is competitive, it is government-backed, and her post office is walking distance. ₹5 lakh grows to roughly ₹6,13,000 by maturity.
POTD vs Bank FD
| Feature | Post Office TD | Bank FD |
|---|---|---|
| Runs it | Govt of India | Banks |
| Safety | Sovereign, no cap | DICGC ≤ ₹5L |
| Rates (2026) | 6.9-7.5% | 6.75-7.25% majors |
| Senior bonus | None | +0.50-0.75% |
| Online | Limited | Fully digital |
| TDS | None | >₹40K/yr (₹50K sr) |
The Real Difference: The Backing
Sovereign vs DICGC ₹5 Lakh
POTD: backed by the Government of India's sovereign guarantee, no deposit limit.
Bank FD: DICGC insures up to ₹5 lakh per depositor per bank. ₹10 lakh in one failed bank returns only ₹5 lakh — though major-bank failures are extremely rare. Below ₹5 lakh, the distinction is academic; above it, POTD wins on protection.
Account Features
✓ Transfer: account moves freely between post offices across India.
✓ Nomination: up to 3 nominees via Form SB 8, with set shares. Strongly recommended.
✓ Loan: after 6 months, borrow up to 75% of value at ~2% above your POTD rate.
✓ Eligibility: resident Indians only; NRIs cannot open or renew.
Part II
The 5-Year 80C Benefit, Taxation at Slab, and TDS
Why only the 5-year tenure earns a Section 80C deduction, why it works only under the Old Tax Regime, why the deduction never covers the interest, and how POTD interest is taxed at your slab rate with no TDS deducted at source.
Part II · Page 6
The 5-Year 80C Deduction
Up to ₹1.5 Lakh — Old Regime Only
Investing in the 5-year POTD lets you reduce taxable income by up to ₹1.5 lakh under Section 80C — but only if you are in the Old Tax Regime. The ₹1.5 lakh ceiling is shared across all 80C investments (EPF, PPF, NSC, ELSS, tax-saver FD, life insurance, home-loan principal). 1/2/3-year tenures do not qualify.
New Regime Users Get Nothing
The New Tax Regime (default since FY 2023-24) offers lower rates but no deductions. If you have not actively opted back into the Old Regime, the 5-year POTD gives you zero tax benefit — you get only the 7.5% interest. Most young professionals fall here.
Worked Example: Tax Saved
Rahul, ₹12L salary, Old Regime, invests ₹1.5L in a 5-year POTD. Gross ₹12,00,000 − standard deduction ₹50,000 − 80C ₹1,50,000 = taxable ₹10,00,000. Tax (Old slabs FY 2025-26) works out to ₹1,12,500 + 4% cess ≈ ₹1,17,000, versus ~₹1,47,000 without the 80C investment. Tax saved: ~₹30,000 — a 20% return on the ₹1.5L just from the deduction, before the 7.5% interest.
Taxation of Interest
| Item | Treatment |
|---|---|
| Interest | Added to income, taxed at slab |
| TDS | None deducted |
| Declaration | Must self-report |
| 5-yr investment | 80C deductible (Old) |
"Tax-Saving FD" ≠ Tax-Free
A common myth. The investment earns the 80C deduction; the interest is fully taxable each year at your slab. On ₹1.5L at 7.5%, the ~₹11,250 annual interest adds to income — about ₹3,375 of tax in the 30% slab. You still come out ahead (deduction > tax on interest), but returns are not tax-free.
No TDS, But Still Taxable
Unlike bank FDs — which deduct TDS once interest crosses ₹40,000 a year (₹50,000 for seniors) — POTD deducts no TDS. This is not a loophole: the interest remains fully taxable at your slab and must be declared in your return.
Should You Use 5-Year POTD for 80C?
✓ Yes if: Old Regime, 80C limit not yet exhausted, you want safe fixed returns and can lock 5 years.
✕ Skip if: New Regime, EPF/PPF already fills ₹1.5L, you need liquidity, or you can take market risk (ELSS shares the 80C benefit with higher upside).
Part III
Premature Withdrawal, Misconceptions, and Where POTD Fits
The strict early-exit rules and the penalties they impose, four common myths corrected (better returns, tax-free, always beats banks, auto-reinvesting interest), and the three-bucket model that shows where a Post Office Time Deposit belongs in a savings plan.
Part III · Page 8
Premature Withdrawal Rules
| When | Interest You Get |
|---|---|
| First 6 months | No withdrawal allowed |
| Completed years | TD rate − 2% |
| Incomplete period | Savings rate (~4%) |
| 5-yr after 4 yr | 3-year TD rate applies |
Penalty Example
Anjali Exits a 5-Year POTD at 2.5 Years
₹2L at 7.5%. 2 completed years earn 5.5% (7.5% − 2%) ≈ ₹11,540; the incomplete 6 months earn ~4% ≈ ₹2,000. Total ≈ ₹2,13,540. The real cost is not just the 2% cut — it is the opportunity cost of not having chosen a tenure matching her actual horizon.
The Pro Tip
If there is even a 20% chance you will need the money in 2-3 years, choose a shorter tenure. The rate gap (7.0% for 2-year vs 7.5% for 5-year) is only 0.5% — far smaller than the 2% premature-withdrawal penalty.
Four Misconceptions
"Government-backed means better returns"
Backing means safety, not yield. At 7.5% max, POTD is only marginally above major-bank FDs because the sovereign guarantee is itself the draw.
"5-year POTD is tax-free"
Only the investment is 80C-deductible (Old Regime). The interest is fully taxed at your slab every year.
"Post office always beats banks"
Depends. Seniors do better with a bank FD (+0.50-0.75%) or SCSS (8.2%); banks win on digital access.
"Interest auto-reinvests"
It does not. Interest is paid annually to your savings account; set a standing instruction to compound it.
Where POTD Fits: Three Buckets
Emergency Liquidity (3-6 mo)
Needs instant access. Right fit: savings account, liquid funds. POTD: wrong — 6-month lock-in too rigid.
Short-Term Goals (1-5 yr)
Fixed date, capital safety critical. Right fit: POTD, bank FD. POTD: perfect for defined 1-5 year goals.
Long-Term Wealth (10+ yr)
Needs inflation-beating growth. Right fit: equity funds, PPF, NPS. POTD: wrong — 7.5% barely beats inflation.
Where POTD Excels vs Fails
| Strength | Weakness |
|---|---|
| Defined goal dates | Emergency access |
| Risk-averse savers | Beating inflation |
| Sovereign safety, no cap | Wealth multiplication |
| Safe 80C (5-yr, Old) | Senior-citizen bonus |
Senior-Citizen Note
If you are 60+, the Senior Citizens Savings Scheme (SCSS) pays 8.2% — well above POTD (7.5%) and most bank FDs. The catch: a ₹30 lakh deposit cap and seniors-only eligibility. POTD offers no extra rate for seniors.
Part IV
The Verdict
Certainty by design. Not growth.
Part IV: The Verdict · Page 10
30-Second Summary
A Post Office Time Deposit is the post-office equivalent of a bank FD, run by the Government of India through India Post. Lock a lump sum (min ₹1,000, no cap) for 1, 2, 3 or 5 years at government-set, quarterly-revised rates — 6.9% to 7.5% for Jan-Mar 2026, unchanged since April 2024. Interest is calculated quarterly and paid annually. The defining advantage is the unlimited sovereign guarantee, not the rate, which sits within ~0.5% of bank FDs.
Only the 5-year tenure earns a Section 80C deduction, and only under the Old Tax Regime; the interest is always taxed at your slab. No TDS is deducted, but interest must be declared. Premature exit is barred for 6 months, then penalised (rate minus 2% on completed years, ~4% on the rest). Use POTD for fixed 1-5 year goals where capital safety is non-negotiable — not for emergencies, not for beating inflation. The certainty is the point.
"POTD is about certainty, not growth. It answers one question — 'how do I guarantee a known sum, safely, on a known date?' — and answers it well. The moment you ask it to do more — to be liquid in a crisis, or to outrun inflation over a decade — it disappoints. The discipline is not in choosing the highest rate; it is in matching the tenure to the goal and leaving the money alone until it matures."
The Final Orientation
ADWIZR · June 2026
Decision Rules
Use Correctly As
✓ Fixed 1-5 year goal money
✓ Tenure matched to goal date
✓ 5-yr for Old-Regime 80C
✓ Uncapped sovereign safety
Misuse Destroys Value
✕ Emergency fund
✕ Long-term wealth building
✕ 5-yr lock-in under New Regime
✕ Expecting to beat inflation
Triggers to Reassess
When to Rethink the Choice
(1) You turn 60 — compare SCSS at 8.2%. (2) Single-bank deposit exceeds ₹5L — POTD's uncapped guarantee becomes valuable. (3) Your horizon shrinks below the chosen tenure — you face the 2% penalty; shorter tenures fit better. (4) You switch to the New Regime — the 5-year 80C benefit vanishes.

Key Terms & Definitions
Post Office Time Deposit (POTD)
Also called the National Savings Time Deposit — a fixed-tenure savings scheme run by the Government of India through post offices. The post-office equivalent of a bank FD, available in 1, 2, 3 and 5-year tenures at government-set, quarterly-revised rates, backed by an unlimited sovereign guarantee.
Sovereign Guarantee
The Government of India's own backing of POTD principal and interest, with no deposit limit. This differs from a bank FD, which is insured by DICGC only up to ₹5 lakh per depositor per bank — making POTD's protection wider for large balances.
Section 80C Deduction
A tax provision allowing up to ₹1.5 lakh of taxable income to be reduced via approved investments. Only the 5-year POTD qualifies, and only under the Old Tax Regime. The deduction applies to the investment, never to the interest, and the ₹1.5 lakh ceiling is shared with EPF, PPF, ELSS and others.
Premature Withdrawal
Early closure of a POTD. Barred entirely in the first 6 months. Thereafter, completed years earn the TD rate minus a 2% penalty and the incomplete period earns only the Post Office Savings Account rate (~4%) — so early exit forfeits a meaningful share of interest.
Quarterly Compounding
POTD interest is calculated every quarter but paid out once a year. Quarterly compounding makes the effective return slightly higher than the headline rate — ₹1,00,000 at 7.5% earns ₹7,714 in year one rather than a simple ₹7,500.
Senior Citizens Savings Scheme (SCSS)
A small-savings scheme for those aged 60+, paying 8.2% — higher than both POTD and most bank FDs. Capped at a ₹30 lakh deposit and limited to seniors, it is generally the better choice for older savers than a POTD, which offers no senior-citizen rate bonus.
