How Post Office MIS works
Post Office Monthly Income Scheme (MIS) is a government-backed, lump-sum savings scheme that generates a fixed monthly income. It is designed for investors who need predictable cash flow — typically retirees, homemakers, or anyone with a lump sum who prefers guaranteed monthly interest over market-linked returns.
Key mechanics:
- Minimum deposit: ₹1,000 (in multiples of ₹100).
- Maximum deposit: ₹9,00,000 per single account; ₹15,00,000 for joint accounts (individual cap still ₹9L).
- Term: 5 years. Renewable on maturity.
- Interest: 7.4% p.a. (Q1 FY 2026-27), paid monthly — no compounding on principal.
- Principal at maturity: Returned in full (no deduction unless prematurely closed).
- Sovereign backing: Government of India guarantee.
How monthly payout is calculated
MIS uses simple interest — the principal does not compound:
Monthly payout = (Principal × Annual rate) ÷ 12
At 7.4% p.a. on ₹9,00,000: Monthly payout = (9,00,000 × 7.4%) ÷ 12 = ₹5,550/month
Over 5 years, the total interest earned = ₹5,550 × 60 = ₹3,33,000.
Deposit limits
| Account type | Maximum deposit |
|---|---|
| Single account | ₹9,00,000 |
| Joint account (2 or 3 adults) | ₹15,00,000 combined |
| Individual limit (all accounts) | ₹9,00,000 (their share of joint + single) |
Premature closure penalty
| Time since opening | Penalty |
|---|---|
| Less than 1 year | Not permitted |
| 1 to 3 years | 2% of principal deducted |
| 3 to 5 years | 1% of principal deducted |
| At 5-year maturity | Full principal returned, no penalty |
Tax treatment
| Item | Rule |
|---|---|
| Monthly interest received | Taxable as ‘Income from Other Sources’ |
| TDS by India Post | Not deducted |
| Section 80C deduction | Not available |
| Principal at maturity | Not taxable |
Compounding your MIS payout
MIS pays simple interest — the ₹5,550/month is not automatically reinvested. To compound your returns, you can open a Post Office RD and deposit your monthly MIS payout:
- MIS payout at ₹9L: ₹5,550/month
- Invest this ₹5,550/month into Post Office RD at 6.7%: builds a parallel compounded corpus
- 5-year RD maturity on ₹5,550/month: approximately ₹3.89 lakh (vs ₹3.33 lakh from simple MIS interest)

Post Office MIS vs Senior Citizens Savings Scheme (SCSS)
| Feature | Post Office MIS | SCSS |
|---|---|---|
| Eligible investors | All adults | 60+ (or 55+ for VRS retirees) |
| Rate (Q1 FY 2026-27) | 7.4% p.a. | 8.2% p.a. |
| Payout frequency | Monthly | Quarterly |
| Maximum deposit | ₹9L (single) | ₹30L |
| 80C deduction | No | Yes |
| Lock-in (no penalty) | 5 years | 5 years |
| Extension | Renewable | 3-year extension allowed |
If you are 60+, SCSS is generally more attractive than MIS due to the higher rate, larger cap, and 80C benefit.
Post Office MIS vs Systematic Withdrawal Plan (SWP)
| Feature | Post Office MIS | SWP (mutual fund) |
|---|---|---|
| Returns | Guaranteed 7.4% | Market-linked (not guaranteed) |
| Principal safety | Sovereign guarantee | Subject to NAV fluctuation |
| Tax on payout | As regular income | Capital gains (can be lower tax) |
| Flexibility | Fixed monthly amount | Adjustable withdrawal amount |
| Suitable for | Risk-averse income seekers | Investors comfortable with market risk |
For risk-averse investors, MIS is the safer choice. For those seeking potentially higher post-tax income with some market exposure, a debt mutual fund SWP may offer better tax efficiency (long-term capital gains taxed at slab vs regular income). Use our SWP calculator to compare.
