Understanding the MDR Shift
For years, UPI operated on a 'zero-MDR' policy. MDR, or Merchant Discount Rate, is a fee merchants pay to banks and payment service providers for processing digital transactions. This fee was waived for UPI to encourage widespread adoption, which was incredibly
successful. However, starting October 15, 2026, this policy has been updated. The National Payments Corporation of India (NPCI) has introduced a 0.4% MDR on person-to-merchant (P2M) UPI transactions above ₹2,000. This charge is not a tax and is meant to be distributed among the payment ecosystem players to cover the costs of infrastructure, security, and innovation. For very large transactions of ₹75,000 or more, the MDR is capped at ₹300.
The Rule: Customers Should Not Be Charged
The most crucial point in the new framework is explicit: merchants are prohibited from passing this MDR cost on to customers. If you buy an item for ₹3,000, you pay exactly ₹3,000. The merchant is the one who bears the 0.4% MDR, which in this case would be ₹12. The government, RBI, and NPCI have all been clear that banks must ensure merchants comply with this rule. The policy is designed to make the UPI system financially sustainable for the companies that run it without burdening the end consumer. Person-to-person (P2P) transfers, like sending money to a friend, remain completely free, as do all merchant transactions up to the ₹2,000 threshold. According to the government, this means around 96% of all merchant UPI transactions will remain free of any MDR for businesses.
Exemptions for Small Businesses and Key Sectors
The framework includes significant protections for small businesses. Merchants receiving up to ₹1 lakh per month via UPI QR codes will remain completely exempt from MDR, even on individual transactions over ₹2,000. This is intended to protect kirana stores and other small vendors who were crucial to UPI's growth. Furthermore, certain essential and thin-margin sectors have special, lower rates. For example, payments for railways, telecom, insurance, and fuel will attract a flat MDR of ₹5 for transactions over ₹2,000, instead of the 0.4% rate. This tiered approach aims to balance the need for ecosystem revenue with the economic realities of different types of businesses.
The Evidence: Reality on the Ground
Despite the clear directive, evidence suggests some merchants are indeed passing the cost on to customers. Reports have noted that some shopkeepers have started adding a small flat fee or percentage for UPI payments above a certain amount, directly violating the rules. While officials are monitoring compliance, the practice stems from the economic pressure on businesses operating with thin profit margins. For these merchants, even a small percentage fee on a large transaction can feel significant. This has led to concerns that some businesses might start discouraging UPI payments for larger amounts and ask customers to pay with cash instead, potentially undermining the very goal of digital adoption.
The Bigger Picture: Sustainability vs. Adoption
The introduction of a calibrated MDR marks a major turning point for India's digital payments journey. For years, the zero-MDR policy was funded by government incentives and the payment industry itself, which many argued was unsustainable as transaction volumes soared into the trillions of rupees. The operational cost of running the massive UPI network is substantial, estimated to be between ₹0.4 to ₹1 per transaction. Proponents of the new system, including the RBI, argue that allowing the ecosystem to generate its own revenue is vital for long-term investment in technology, fraud prevention, and expansion into rural areas. The challenge lies in striking a balance: creating a self-sustaining financial model without penalizing the small merchants and consumers who made UPI a global success story.
