What is the Post Office Savings Account interest rate in 2026?

The Post Office Savings Account pays 4.0% per annum, fixed by the Government of India and reviewed quarterly. It has remained at 4% since 2011. Interest is calculated monthly on the minimum balance between the 10th and month-end, and credited once a year on March 31.

Is Post Office Savings Account interest tax-free?

Section 10(15)(i) exempts the first ₹3,500 of POSA interest for individual accounts and ₹7,000 for joint accounts. This is exempt income, not a deduction, and works in both the old and new tax regimes. Additionally, Section 80TTA (₹10,000) or 80TTB (₹50,000 for seniors) deductions apply only in the old regime.

What is the minimum balance for a Post Office Savings Account?

A minimum balance of ₹500 must be maintained. If the balance falls below ₹500 at the end of a financial year, a ₹100 penalty is deducted. If the balance reaches zero, the account is automatically closed.

Is a Post Office Savings Account safer than a bank account?

POSA carries a direct sovereign guarantee from the Government of India with no insurance ceiling, so the entire balance is backed regardless of amount. Bank savings are protected by DICGC insurance only up to ₹5 lakh per depositor per bank. For large sums, combining both diversifies deposit risk.

Q: Can I link Post Office Savings Account to UPI?

POSA does not support native UPI. The workaround is to open an India Post Payments Bank (IPPB) account and link it to your POSA, enabling UPI, IMPS/NEFT, bill payments and sweep-in/sweep-out between the two while keeping the sovereign backing.

Sovereign-Backed. 4% Fixed. The Conservative Parking Layer.

Published as on 29 June 2026

A Post Office Savings Account (POSA) is a government-backed deposit account run by India Post under the Department of Posts. It pays a fixed 4.0% per annum, set by the Government of India and reviewed quarterly — nearly double most bank savings rates (2.50-2.75%). Backed by a direct sovereign guarantee, not DICGC insurance. Section 10(15)(i) exempts the first ₹3,500 of interest (₹7,000 joint) in both tax regimes. Minimum balance ₹500. Best understood as a safe, liquid storage layer for idle cash — not an investment for growth, and not a substitute for a transaction bank account.

Executive Summary · 6 Findings

The Post Office Savings Account answers a narrow but real question: where do I keep idle cash safely, with government backing, when I value sovereign comfort over high returns? POSA earns 4% — almost twice a typical bank savings account — but offers limited digital features. It is a conservative storage layer, not a transaction account, emergency fund, or wealth creator.

Covers what POSA is and why it exists (financial inclusion across ~1.56 lakh post offices), the two-layer tax treatment (Section 10(15)(i) exemption plus 80TTA/80TTB), the 10th-to-month-end interest rule, sovereign guarantee vs DICGC, comparison with bank savings, time deposits and PPF, who it suits, common mistakes, and eight retail questions.

Key Findings

4% fixed — nearly double a bank savings account.

POSA pays 4.0% p.a., set by the Government of India and reviewed quarterly (unchanged since 2011). Most bank savings accounts pay 2.50-2.75%. Interest is calculated monthly on the balance held between the 10th and month-end, and credited once a year on March 31 — not quarterly like banks.

Sovereign guarantee, no insurance ceiling.

Bank deposits are insured by DICGC only up to ₹5 lakh per depositor per bank. POSA carries a direct Government of India guarantee with no limit — the entire balance is backed. No depositor has ever lost money in POSA across decades of economic stress.

Section 10(15)(i): tax-free in both regimes.

The first ₹3,500 of POSA interest (₹7,000 for joint accounts) is exempt income under Section 10(15)(i) — it never enters gross total income. Unlike 80TTA/80TTB (old regime only), this works in the new regime too, making POSA mathematically superior to bank savings for new-regime users.

₹500 minimum — and the penalty is real.

₹500 must be maintained. Fall below it at financial year-end and ₹100 is deducted; hit zero and the account is closed automatically. Aadhaar must be linked within 6 months and PAN within 2 months, or the account becomes inactive.

The 10th-to-month-end rule loses interest silently.

Interest is paid on the lowest balance between the 10th and the last day of each month. Withdraw after the 10th and drop below ₹500, and you earn ZERO interest for that entire month — even if the balance was high for the first two weeks. Time large withdrawals before the 10th.

Storage layer — not an inflation-beater.

As of Feb 2026, POSA's 4% trails 4.8% CPI inflation: a real return of -0.8%. It preserves capital better than cash at home (which loses the full 4.8%) but does not build wealth. Match it to the right job — safe, liquid parking with government backing — and it works exactly as designed.

30% bracket. POSA: ₹3,500 exempt under 10(15)(i), ₹500 taxed at 30% = ₹150. Bank savings in the new regime loses 80TTA entirely. Under the new regime, POSA delivers roughly 2× the post-tax return of a bank savings account.

The Opening · Page 3

The Opening

A Post Office Savings Account is a deposit account operated by India Post — the government postal network. Like a bank savings account, it stores money securely with government backing, earns modest interest (4% per year), and lets you withdraw whenever needed. The core difference is purpose: POSA is built for capital safety and liquidity, not growth. Keep ₹50,000 in it and you earn ₹2,000 a year (₹167 a month). That is not competing with mutual funds or FDs — it is a safe holding place that pays more than a shoebox under the bed.

"POSA lives in the 'conservative storage' layer of your financial life — below the transaction account, beside the emergency buffer, far from the growth layer. It exists to solve inclusion and trust, not to compete with commercial banking. India has roughly 1.56 lakh post offices, over 90% of them rural — penetration no bank network matches."
The Storage-Layer Frame

The mathematics. 4.0% per annum, fixed by government, reviewed quarterly but stable since 2011. Interest is calculated monthly on the balance between the 10th and month-end, and credited annually on March 31. Section 10(15)(i) exempts the first ₹3,500 (₹7,000 joint) in both tax regimes. Minimum balance ₹500, ₹100 penalty if breached at year-end, account closes at zero.

Feb 2026 context. CPI inflation at 4.8% puts POSA's real return at -0.8% — preservation, not growth. For new-regime savers who have lost the 80TTA deduction, POSA's exempt-income status makes it about twice as tax-efficient as a bank savings account earning 2.7%. Linking to India Post Payments Bank (IPPB) adds UPI and digital transfers without sacrificing the sovereign backing.

The Honest Boundary: POSA is NOT an investment — it will not beat inflation (4% vs 4.8% CPI). It is NOT a transaction account — native UPI/NEFT are absent (use IPPB to bridge). It is NOT for large idle sums — ₹5 lakh+ belongs in liquid or ultra-short debt funds earning 6-7%. It IS government-backed, liquid storage at a modestly better rate than most bank savings accounts, with unmatched rural access.

How POSA Works: Features, the Interest Rule, and Account Mechanics

Account opening and eligibility, how interest is actually calculated and credited, the 10th-to-month-end rule that quietly costs careless savers, access methods, and the dormancy rules — the operational details that decide whether POSA earns its 4%.

Part I · Page 4

Account Opening & Eligibility

Criterion	Rule
Min deposit	₹500 to open and maintain
Who can open	Resident individual / joint (≤3)
Minors	10+ in own name; guardian if below
Nomination	Mandatory at opening
KYC linking	Aadhaar in 6 mo, PAN in 2 mo

The Balance Rule

₹500 Floor — Penalty & Closure

Maintain ₹500 at all times. If the balance falls below ₹500 at the end of any financial year, ₹100 is deducted as penalty. If the balance reaches zero, the account is closed automatically. Documents needed: ID proof (Aadhaar/PAN/Voter ID/Passport), address proof, one photo, nomination.

Access & Dormancy

Access: passbook withdrawal at any post office, cheque facility (if opted), ATM/debit card (select branches), limited transfers via India Post Mobile Banking.

Dormancy: no transactions for 3 consecutive financial years → dormant (not closed; money safe). Revive by updating KYC and presenting the passbook; interest continues to accrue if balance stays above ₹500.

Interest Calculation & Credit

Element	Detail
Rate	4.0% p.a. (since 2011)
Set by	Govt of India, quarterly review
Calculated	Monthly, on 10th-to-month-end balance
Credited	Annually, March 31
Below ₹500	No interest that month

The 10th-to-Month-End Rule

Where Interest Is Quietly Lost

Interest is paid on the lowest balance held between the 10th and the last day of each month.

Example: withdraw ₹80,000 on 15 January, dropping the balance to ₹200 (below ₹500). You lose January's entire interest, despite holding ₹80,000+ for the first 14 days.

Fix: make large withdrawals before the 10th of the month.

Worked Example

✓ Hold ₹50,000 from 1 April to 31 March.

✓ Never drop below ₹500 between the 10th and month-end.

✓ Annual interest: ₹50,000 × 4% = ₹2,000.

✓ Credited once, on 31 March.

The operational insight: POSA's 4% is only fully earned if you respect the calendar. Treat it as a place for stable, long-horizon idle cash that will not need mid-month withdrawals — and keep your day-to-day money in a bank or IPPB account for transactions.

Part II

Tax Treatment, Safety, and Comparison with a Bank Savings Account

The two-layer tax structure — Section 10(15)(i) exempt income (both regimes) plus 80TTA/80TTB deductions (old regime only) — why sovereign backing differs from DICGC insurance, and where POSA beats or loses to a bank savings account.

Part II · Page 6

Two-Layer Tax Treatment

Layer 1 — Section 10(15)(i) (Both Regimes)

First ₹3,500 of interest tax-free (individual); ₹7,000 (joint). This is exempt income, not a deduction — it never enters gross total income, and it works in both the old and new tax regimes.

Layer 2 — 80TTA / 80TTB (Old Regime Only)

80TTA (below 60): ₹10,000 deduction on savings interest from all sources combined.
80TTB (60+): ₹50,000 deduction on interest from all deposits (savings + FD + post office). Both apply only in the old regime.

Worked: New-Regime Saver

POSA interest ₹4,000 → ₹3,500 exempt under 10(15)(i), ₹500 taxable. Bank interest ₹8,000 fully taxable (no 80TTA in new regime). Net effect: POSA's exempt status preserves efficiency exactly where bank savings loses it.

TDS

No TDS in practice — POSA interest rarely crosses thresholds. It would take ₹10 lakh+ parked at 4% to approach the ₹40,000 (₹50,000 senior) TDS trigger, which defeats POSA's purpose.

Safety: Sovereign vs DICGC

Aspect	POSA	Bank
Backing	Sovereign	DICGC ≤ ₹5L
Ceiling	None	₹5L / bank
Risk	Govt default (~nil)	Bank failure
History	No depositor loss	Yes Bank, LVB stress

For amounts above ₹5 lakh, splitting across banks (₹5L each, DICGC) plus POSA (sovereign) diversifies deposit risk better than one bank holding everything.

POSA vs Bank Savings

Feature	POSA	Bank Savings
Rate	4.0%	2.50-2.75%
Credit	Annual	Quarterly
Digital	Limited (IPPB)	Full UPI/NEFT
Nominee	Mandatory	Optional
Reach	1.56L offices, 90% rural	Urban-skewed

The honest truth: this is not "better or worse" — it is different institutional design. POSA prioritises sovereign backing and rural access; banks prioritise convenience and digital sophistication. For most urban professionals, a bank account for transactions plus liquid funds for emergencies beats POSA on returns and convenience. POSA wins for the elderly, rural savers, and new-regime parkers wanting simple government-backed storage.

Part III

Who It Suits, Common Mistakes, and How It Compares to Liquid Funds, PPF & Time Deposits

The five situations where POSA genuinely fits, the five mistakes that waste its value (treating it as an investment, comparing only nominal rates, holding it against credit-card debt), and where it sits against liquid mutual funds, PPF, and the Post Office Time Deposit.

Part III · Page 8

When POSA Fits

Sovereign-backing psychology

For deeply risk-averse savers — a 70-year-old who distrusts private banks but needs somewhere better than a steel almirah for ₹2 lakh of idle cash.

Rural / remote access

Where the nearest bank is 20 km away but the post office is 2 km — physical proximity outweighs digital features.

Deposit-risk diversification

Already at the ₹5L DICGC limit in a bank? Split, e.g. ₹5L bank FD plus ₹3L POSA, to spread risk across two backing structures.

New-regime parking

No 80TTA in the new regime. POSA ≈3.85% post-tax vs bank savings ≈1.89% — roughly twice the post-tax return for idle cash.

Semi-digital via IPPB

Link POSA to an IPPB account for UPI, IMPS/NEFT, bill pay and sweep facilities — government backing with a digital bridge.

vs PPF & Time Deposit

Feature	POSA	PPF / TD
Rate	4.0%	PPF 7.1% / TD 6.9-7.5%
Liquidity	Anytime	Locked / tenured
80C	No	PPF & 5-yr TD: Yes
Use For	0-2 yr parking	Long-term / fixed tenure

Five Common Mistakes

Treating POSA as an investment

₹10 lakh "for growth" becomes ₹10.4 lakh while 4.8% inflation erodes it. POSA is capital preservation, not wealth creation — for growth, use equity funds.

Comparing only nominal rates

"FD gives 7%, POSA 4%, so FD wins" ignores tax treatment (especially the new regime), liquidity, and backing. Compare post-tax, post-liquidity returns for your case.

Holding POSA while paying card interest

Earning ₹4,000 at 4% while carrying ₹50,000 card debt at 36-42% loses ₹14,000+ net. Clear high-interest debt first.

Not linking Aadhaar / PAN on time

Account turns inoperative if Aadhaar is unlinked in 6 months or PAN in 2 months. Complete KYC in the first month.

Ignoring the 10th-to-month-end rule

A mid-month withdrawal below ₹500 forfeits the whole month's interest. Time withdrawals before the 10th.

vs Liquid Mutual Fund

✓ POSA: zero NAV risk, government backing, small amounts, physical passbook preference.

✓ Liquid fund: ₹1L+ idle cash, 6-7% returns, 1-day withdrawal, comfortable with NAV (per-unit market value, not guaranteed).

The reassessment trigger: if ₹5 lakh+ sits idle in POSA earning 4% while inflation runs 4.8%, move the surplus to liquid or ultra-short debt funds for better real returns. POSA was never built to beat FDs or inflation — expecting 8% from a 4% account is a category mismatch, not a product failure.

Part IV

The Verdict

Assign the right job. It works exactly as designed.

Part IV: The Verdict · Page 10

30-Second Summary

A Post Office Savings Account is a government-run savings account earning a fixed 4% — nearly double most bank savings rates (2.50-2.75%) — but without advanced digital features. Backed by a direct sovereign guarantee with no insurance ceiling, not DICGC. Section 10(15)(i) keeps the first ₹3,500 (₹7,000 joint) of interest tax-free in both regimes. Minimum balance ₹500; interest calculated monthly on the 10th-to-month-end balance and credited annually on March 31.

It is a conservative storage layer for idle cash you might need in 1-2 years — not a transaction account, emergency fund, or wealth creator. As of Feb 2026 its 4% trails 4.8% CPI for a -0.8% real return: preservation, not growth. It shines for new-regime savers (where 80TTA is gone), rural savers, the elderly preferring physical banking, and as deposit-risk diversification above the ₹5L DICGC limit. Link to IPPB to add UPI without losing the backing.

"Financial clarity comes from matching tools to jobs, not judging every tool by investment-return standards. POSA is neither exciting nor high-performing — it will not double your money or beat inflation. But it does one thing well: government-backed, liquid storage at a modestly better rate than most bank savings accounts. Give it the right job and it works exactly as designed."
The Final Orientation

The Bottom Line: Use POSA for safe, liquid parking of idle cash where you value sovereign backing or need rural post-office access — ideally under ₹1 lakh, or as a deposit-risk split above the ₹5L DICGC ceiling. It is especially compelling in the new tax regime, delivering roughly twice the post-tax return of a bank savings account. Do NOT use it for growth, large idle sums, full digital banking, or money needing frequent mid-month withdrawals. Respect the ₹500 floor and the 10th-to-month-end rule, link Aadhaar/PAN on time, and clear high-interest debt before optimising savings.

Investor FAQ

Questions Indian Savers Ask

Eight questions, answered directly.

Investor FAQ · Page 12

Frequently Asked Questions

Q1 Can I open more than one POSA?

No — only one single account per person at any one post office. You can, however, also participate in multiple joint accounts where you are not the primary holder. If you relocate, you can transfer your account to another post office branch at no extra cost.

Q2 How does POSA interest compare to inflation?

As of Feb 2026, POSA pays 4.0% while CPI inflation is 4.8% — a real return of -0.8%. POSA preserves capital in nominal terms but purchasing power slowly erodes. Cash at home loses the full 4.8%; liquid funds (6-7%) gain over inflation; equity (10-12% long term) gains far more. POSA is a capital-preservation tool, not an inflation-beater.

Q3 Is POSA better than a bank savings account?

It depends on what you optimise for. POSA wins on rate (4% vs 2.50-2.75%), sovereign backing (no ceiling), post-tax return under the new regime, and rural reach. Banks win on digital features (UPI/NEFT), quarterly credit, bill-pay/standing instructions, and auto-sweep to FD. Most urban professionals are better served by a bank account plus liquid funds; the elderly, rural and new-regime savers may prefer POSA.

Q4 Can NRIs open a POSA?

No — POSA is available only to resident Indians. NRIs use NRE/NRO accounts at banks; most post office products require resident status. If you move abroad after opening a POSA, inform the post office and close or convert the account per RBI/FEMA guidelines to stay compliant.

Q5 What if I don't operate it for years?

With no transactions for 3 consecutive financial years, the account becomes dormant — not closed; your money is safe but you cannot transact. Revive it at any branch with the original passbook and updated KYC (Aadhaar, PAN, photo); reactivation typically takes 2-3 working days. Interest keeps accruing during dormancy as long as the balance stays above ₹500.

Q6 POSA or Post Office Time Deposit?

Different jobs. POSA (4%) is liquid, anytime-access savings. The Post Office Time Deposit (6.9-7.5% depending on tenure) is a 1-5 year fixed deposit, locked till maturity with a penalty for early exit; the 5-year variant gives an 80C deduction in the old regime. Use POSA for an emergency buffer or short-term parking; use the TD when you can lock funds for higher guaranteed returns.

Q7 How safe is my money vs a bank?

Both are very safe but backed differently. POSA has a direct Government of India guarantee with no insurance limit — the whole balance is backed, and no depositor has ever lost money in POSA. Bank savings are insured by DICGC only up to ₹5 lakh per depositor per bank; beyond that you are an unsecured creditor if the bank fails. For sums above ₹5 lakh, splitting across banks plus POSA diversifies safety.

Q8 Can I link POSA to UPI?

Not directly — POSA has no native UPI. The workaround is to open an India Post Payments Bank (IPPB) account and link it to your POSA, enabling UPI, IMPS/NEFT, bill payments and sweep-in/sweep-out between the two. This bridges the conservative-storage and transaction layers without sacrificing the sovereign backing.

Key Terms & Definitions

Post Office Savings Account (POSA)

A government-backed savings deposit account operated by India Post under the Department of Posts. Pays a fixed 4.0% per annum set by the Government of India, with a sovereign guarantee rather than DICGC insurance. Designed for capital safety and liquidity, not growth.

Section 10(15)(i) Exemption

Tax provision exempting the first ₹3,500 of POSA interest for individual accounts (₹7,000 for joint) as exempt income — it never enters gross total income. Critically, it applies in both the old and new tax regimes, unlike 80TTA/80TTB.

Section 80TTA / 80TTB

Deductions on interest income in the old tax regime only. 80TTA gives non-seniors up to ₹10,000 on savings interest from all sources combined; 80TTB gives seniors (60+) up to ₹50,000 on interest from all deposits (savings, FD and post office).

Sovereign Guarantee vs DICGC

POSA is backed directly by the Government of India with no insurance ceiling — the entire balance is protected. Bank deposits are insured by the Deposit Insurance and Credit Guarantee Corporation only up to ₹5 lakh per depositor per bank.

10th-to-Month-End Rule

POSA interest is calculated on the lowest balance held between the 10th and the last day of each month. A withdrawal after the 10th that drops the balance below ₹500 forfeits the entire month's interest, even if a high balance was held earlier in the month.

India Post Payments Bank (IPPB)

A payments bank under India Post that can be linked to a POSA to add UPI, IMPS/NEFT, bill payments and sweep-in/sweep-out — providing digital convenience while preserving the sovereign-backed storage of the underlying savings account.
