How It Works
The Post Office Monthly Income Scheme (POMIS) is a small-savings deposit that pays a fixed interest amount into your linked savings account every month. You deposit a lump sum, lock it in for 5 years, and receive monthly interest at the rate prevailing on the date of deposit. The principal is returned in full at maturity.
Monthly Interest Formula
Monthly interest = Deposit × Rate% ÷ 100 ÷ 12
POMIS uses simple interest — there is no compounding because the interest is paid out every month rather than reinvested. Annual interest is simply the monthly payout multiplied by 12, and the total interest over the 5-year tenure is the annual interest multiplied by 5.
Deposit limits and account types
The minimum deposit is ₹1,000 and must be in multiples of ₹1,000. The maximum is ₹9 lakh for a single-holder account and ₹15 lakh for a joint account (up to 3 holders). These limits were raised in Union Budget 2023 from ₹4.5 lakh and ₹9 lakh respectively. You may hold multiple POMIS accounts at one or more post offices, but the combined balance — including your share in joint accounts — cannot exceed these caps.
Tax treatment
The principal does not qualify for a Section 80C deduction. Interest is fully taxable as Income from Other Sources at your marginal slab. The Post Office does not deduct TDS, but you must declare the interest in your ITR. Senior citizens can claim a Section 80TTB deduction of up to ₹50,000 per year against interest income from all small-savings and bank deposits combined.
Premature withdrawal
Withdrawal is not allowed in the first year. A 2% penalty on the principal applies between years 1 and 3, and a 1% penalty applies between years 3 and 5. At maturity the full principal is returned with no penalty.
Frequently Asked Questions
The Post Office Monthly Income Scheme rate is 7.4% per annum for Q1 FY 2026-27. The rate is revised quarterly by the Ministry of Finance and notified through small-savings circulars. The rate that applies to your account is the rate prevailing on the date of deposit and stays fixed for the full 5-year tenure of that account — later rate changes do not affect existing deposits.
