What is the New MDR Rule?
Starting from October 15, 2026, the National Payments Corporation of India (NPCI) has introduced a Merchant Discount Rate (MDR) on certain Unified Payments Interface (UPI) transactions. Specifically, a charge of 0.4% will apply to person-to-merchant (P2M)
payments valued over ₹2,000. It's crucial to understand that this is not a charge on customers. All person-to-person (P2P) transfers—like sending money to friends or family—remain completely free, regardless of the amount. The new rule targets the business payment ecosystem to create a sustainable revenue model for the operators who keep the massive UPI infrastructure running.
Decoding the Merchant Discount Rate (MDR)
MDR is not a new concept; it's a standard fee that merchants have long paid for accepting payments via credit or debit cards. It’s essentially a processing fee that covers the cost of the transaction. In the UPI context, this fee is now being applied to larger merchant transactions. The 0.4% rate is significantly lower than typical credit card MDRs, which can range from 1.5% to 2.5%. For very high-value UPI payments of ₹75,000 or more, the MDR is capped at a maximum of ₹300 per transaction. So, even on a payment of ₹1 lakh, the merchant would only pay ₹300, not ₹400. This money is not a government tax; it is distributed among the players in the payment ecosystem, such as the banks and payment app providers.
Who Actually Pays the Charge?
The MDR is borne by the merchant receiving the payment, not the customer making it. The government and NPCI have been clear that banks should ensure merchants do not pass this cost on to consumers by adding a surcharge at checkout. For example, if you buy an item for ₹5,000, your bank account will be debited for exactly ₹5,000. The merchant, in turn, will receive ₹4,980 after the ₹20 MDR (0.4% of ₹5,000) is deducted. This structure is intended to make merchants contribute to the upkeep of the digital payment infrastructure they benefit from. The revenue helps fund everything from server maintenance to cybersecurity.
Are Small Businesses Exempt?
Yes, there are important protections for small businesses. The MDR framework does not apply to small merchants classified under the 'P2PM' (Person-to-Person Merchant) category. This category includes small vendors, like street food sellers and local kirana stores, who receive up to ₹1 lakh per month via UPI QR codes. These merchants will continue to enjoy zero MDR on all transactions, even those above ₹2,000. This exemption is designed to protect the vast majority of small retailers who have been crucial to UPI's widespread adoption and ensures that going digital remains cost-free for them. The government estimates that over 95% of all merchant transactions will remain unaffected by the new charge.
Special Rates for Essential Services
Recognising that a percentage-based fee could be burdensome for sectors with thin margins, the framework includes special concessional rates for essential services. Instead of the standard 0.4%, a flat MDR of just ₹5 will apply to transactions over ₹2,000 for categories like railways, fuel, insurance, telecom, and utility bill payments. This flat-rate model provides cost certainty for critical industries. Similarly, capital market transactions, such as payments for mutual funds or to stockbrokers, will attract a minimal MDR of 0.02%, capped at ₹300, to encourage retail investment.
Why Was This Change Necessary?
For years, the UPI ecosystem operated on a zero-MDR regime, with the government providing subsidies to support the payment infrastructure. However, relying solely on government incentives was not seen as a sustainable long-term model for an ecosystem that processes billions of transactions monthly. Introducing a nominal MDR on high-value business transactions provides a reliable revenue stream for banks and fintech companies. This income incentivises them to invest further in technology, security, and expanding the payments network into rural and semi-urban areas, ultimately strengthening the entire digital payments landscape.
