India's UPI Charges Set to Change: Merchants Face New Fees From October 15

India's wildly popular Unified Payments Interface (UPI) is about to get a price tag for businesses, marking a significant shift in its operating model. From October 15, 2026, the National Payments Corporation of India (NPCI) will implement a 0.4% Merchant Discount Rate (MDR) on Person-to-Merchant (P2M) UPI transactions exceeding ₹2,000. This move, officially notified by the Central Government and detailed by NPCI on September 15, 2026, aims to build a sustainable revenue model for the rapidly expanding digital payment ecosystem. The new charges are a direct outcome of the Payment and Settlement Systems Act, 2007 being amended in August 2026, which removed the statutory ban on MDR for UPI. While Person-to-Person (P2P) transfers and P2M transactions up to ₹2,000 will remain free, larger payments to businesses will incur this fee, capped at ₹300 for transactions of ₹75,000 and above. Small merchants earning up to ₹1 lakh monthly via UPI QR codes are also exempt under a special Person-to-Person-Merchant (P2PM) framework. Certain sectors like railways, telecom, and fuel will see a flat ₹5 MDR for transactions over ₹2,000. This marks an end to nearly six years of entirely free UPI for many merchant categories, a policy that significantly drove its mass adoption across India. While the government has 'advised' banks to prevent merchants from passing these MDR costs to customers, concerns are already bubbling among businesses about potential impacts on operating margins and possible downstream price adjustments. The coming weeks will see payment aggregators and fintech platforms scrambling to update their systems before the October 15 deadline. As India grapples with the 'who pays for convenience?' question, all eyes will be on how this new fee structure influences the future trajectory of its world-leading digital payments infrastructure and whether it truly achieves financial sustainability without hindering growth.
