What Is IMPS?
IMPS (Immediate Payment Service) is an NPCI system that transfers money between bank accounts instantly, 24×7, including weekends and holidays. It works through mobile and net banking using the account number and IFSC (or a mobile number and MMID), and is typically capped around ₹5 lakh.
Why IMPS matters
IMPS fills the gap between instant everyday UPI payments and larger NEFT/RTGS transfers. When you need money to arrive immediately — a mid-sized transfer at midnight, or an urgent payment on a holiday — IMPS delivers.
It also underpins UPI: UPI payments settle over IMPS rails, which is why they clear instantly around the clock.
How IMPS works
You send an IMPS transfer through your bank app or net banking using either the beneficiary’s account number and IFSC code, or their mobile number and MMID. The transfer is processed and credited instantly, any time of day or night. Most banks cap IMPS around ₹5 lakh per transaction, and a small fee may apply for larger amounts.
A real Indian example of IMPS
On a Sunday night, Priya needs to send ₹1,50,000 to a family member urgently. NEFT would work but she wants it credited instantly, and the amount is below the ₹2 lakh RTGS floor. IMPS is the perfect fit: she initiates the transfer with the account number and IFSC code, and the money arrives in seconds, even outside banking hours.
