The Post Office Monthly Income Scheme (POMIS) is one of India's most trusted savings instruments, backed by the Government of India through India Post. It offers a fixed monthly income on a lump-sum investment, making it especially attractive for retirees, senior citizens, and anyone seeking a predictable, risk-free income stream without equity market exposure.

In this complete guide, we cover everything you need to know about POMIS in 2025 — the current interest rate, investment limits, eligibility, tax treatment, premature withdrawal rules, and a step-by-step explanation of how to calculate your monthly returns.

What Is the Post Office Monthly Income Scheme (POMIS)?

POMIS is a small savings scheme managed by India Post under the Ministry of Finance. You make a one-time deposit, and the post office pays you a fixed interest every month for 5 years. At the end of the 5-year tenure, your original deposit is returned in full.

The scheme is not market-linked — your returns are entirely determined by the government-notified interest rate, which is revised quarterly. This makes it one of the safest ways to generate passive monthly income in India.

Key characteristics of POMIS:

• Government-backed — zero default risk
• Fixed monthly payout — simple interest, not compounded
• 5-year fixed tenure
• Open to resident Indian individuals and minors
• Premature withdrawal allowed after 1 year (with penalty)

Post Office MIS Interest Rate in 2025

The interest rate for Post Office MIS is announced quarterly by the Ministry of Finance. It has been stable at 7.4% per annum for several consecutive quarters, making it competitive with many bank fixed deposits of similar tenure.

The rate is reviewed every quarter. Always verify the latest rate at your nearest post office or the India Post official website before investing.

Investment Limits: Single and Joint Accounts

One of the most important aspects of POMIS planning is knowing the investment limits by account type. These limits apply per individual, not per account.

All deposits must be in multiples of ₹1,000. In a joint account, all holders have equal share of the deposit. Importantly, each individual's total across all POMIS accounts (single + share in joint) must not exceed ₹9 lakh.

Who Is Eligible for Post Office MIS?

POMIS has straightforward eligibility rules:

• Resident Indians: Any adult resident Indian can open a single or joint account.
• Minors (10+): Minors above 10 years can open an account in their own name.
• Minors (below 10): Guardians can open and operate the account on the minor's behalf.
• Joint accounts: All three joint holders must be resident adults.

How Is Monthly Income Calculated?

The formula is simple — Post Office MIS pays simple interest monthly. There is no compounding involved.

Monthly Income = (Principal × Annual Interest Rate) ÷ 12

Let us work through three real examples:

Example 1 — Retired Teacher from Lucknow (Single Account, ₹9,00,000):

Monthly Income = (₹9,00,000 × 7.4%) ÷ 12 = ₹66,600 ÷ 12 = ₹5,550/month
Total Interest over 5 years = ₹5,550 × 60 = ₹3,33,000
Maturity Amount = ₹9,00,000 (principal returned)

Example 2 — Couple from Pune (Joint Account, ₹15,00,000):

Monthly Income = (₹15,00,000 × 7.4%) ÷ 12 = ₹1,11,000 ÷ 12 = ₹9,250/month
Total Interest over 5 years = ₹9,250 × 60 = ₹5,55,000
Maturity Amount = ₹15,00,000

Example 3 — International Comparison (₹5,00,000 ≈ $6,000 USD equivalent):

Monthly Income = (₹5,00,000 × 7.4%) ÷ 12 = ₹3,083/month
Total Interest = ₹3,083 × 60 = ₹1,85,000. At 7.4% p.a., POMIS compares favourably with many developed-market savings accounts offering sub-5% annual yields in 2025.

Premature Withdrawal Rules

POMIS is designed as a 5-year scheme, but premature closure is allowed under specific conditions. Here are the rules:

The penalty is deducted from the principal amount at the time of closure. Any interest already paid to you on a monthly basis is not recovered.

Tax Treatment of Post Office MIS Income

Understanding the tax rules is crucial before investing in POMIS:

• Interest is fully taxable: Monthly interest income is added to your total income and taxed as per your applicable income tax slab.
• No TDS at source: India Post does not deduct TDS on MIS interest. However, this does not mean the income is tax-free. You must self-declare it in your Income Tax Return (ITR).
• Section 80C: POMIS investment does not qualify for deduction under Section 80C.
• Maturity amount: The principal returned at maturity is not taxable as it is your original deposit.

POMIS vs Bank FD vs Other Schemes — A Quick Comparison

POMIS stands out for investors who specifically need monthly income with zero risk to their principal. PPF is better for long-term tax-free wealth creation, while bank FDs offer more flexibility in tenure.

How to Open a Post Office MIS Account

Opening a POMIS account is straightforward and can be done at any post office branch in India:

1. Visit your nearest post office or head post office.
2. Fill in the MIS account opening form (available at the counter).
3. Submit KYC documents: Aadhaar card, PAN card, and a passport-size photograph.
4. Provide a savings account number at the same post office for monthly credit.
5. Make the deposit via cash or cheque in multiples of ₹1,000.
6. Collect your passbook, which serves as proof of investment.

Many post offices also allow account opening and management via the India Post Payments Bank (IPPB) app, making it convenient for digital-first investors.

Frequently Overlooked POMIS Rules

Here are some rules that investors often miss:

• A single individual can hold only one single MIS account but can be a joint holder in multiple joint accounts — as long as the total investment share does not exceed ₹9 lakh.
• The monthly interest is credited to your linked savings account. If uncollected, it does not earn additional interest within the MIS account itself.
• Nomination is mandatory at the time of account opening.
• The account can be transferred from one post office to another anywhere in India.
• On the account holder's death, the nominee or legal heir can claim the deposit plus any pending interest.

Is Post Office MIS Right for You?

POMIS is an excellent choice if you match one or more of these profiles:

• ✅ Retired individuals needing a monthly income supplement
• ✅ Senior citizens who prefer capital safety over high returns
• ✅ Families with surplus savings seeking a steady secondary income
• ✅ Conservative investors who want government-backed returns

It may not be the best fit if you need Section 80C tax benefits, long-term compounding growth, or the flexibility to withdraw anytime within the first year.
