What Exactly is Changing?
Starting October 15, 2026, a Merchant Discount Rate (MDR) of 0.4% will be applied to person-to-merchant (P2M) UPI transactions above ₹2,000. This is not a tax that goes to the government, but a fee that will be shared among the banks and payment companies
that facilitate the transaction. The government has been clear that this charge is to be borne by merchants, not consumers, who will continue to use UPI for free. Importantly, the vast majority of transactions will remain unaffected; person-to-person (P2P) transfers are exempt, as are all merchant payments below the ₹2,000 threshold. This means an estimated 96% of UPI merchant transactions will continue to have zero MDR.
The Problem with 'Free' Payments
Since January 2020, UPI has operated under a zero-MDR regime, a policy designed to drive mass adoption, especially among small merchants who were wary of transaction fees. The strategy worked spectacularly, making UPI the backbone of India's retail payments. However, while the service was free for users and merchants, it was never free to operate. Banks, payment apps like PhonePe and Google Pay, and the National Payments Corporation of India (NPCI) have been bearing the substantial costs of infrastructure, cybersecurity, and customer support. Government subsidies were introduced to help, but they proved insufficient to cover the industry's ever-growing costs as transaction volumes soared into the billions each month.
Why Bring Back MDR Now?
The core reason for reintroducing MDR is financial sustainability. Both the RBI and key players in the payments industry have argued that a viable revenue model is essential for the long-term health and security of the UPI ecosystem. With transaction volumes rising and the average ticket size shrinking, the cost of processing payments has been compounding. The new MDR framework is designed to create a revenue stream to fund necessary investments in technology and security, reducing reliance on government incentives and ensuring the system can continue to scale reliably. The fee structure has been carefully designed, with lower rates for essential sectors and a cap of ₹300 for very large transactions to keep UPI affordable compared to credit or debit cards.
A New Playing Field for Fintech
The return of MDR is set to significantly alter the business models of India's leading fintech companies. For years, major players like PhonePe, Google Pay, and Paytm have been processing massive volumes of UPI transactions with no direct revenue. The MDR provides a long-awaited revenue stream directly from their core payments business. Since the infrastructure is already in place, much of this new revenue could directly boost profitability. This financial boost is expected to trigger a fresh wave of investment in expanding merchant networks, especially in rural and semi-urban areas. Companies like MobiKwik and PhonePe have already indicated that the move strengthens the business case for acquiring more merchants. Furthermore, 5% of the total MDR collected will be put into a dedicated fund to promote UPI adoption among small merchants.
What This Means for Merchants and Users
For consumers, nothing changes directly; UPI remains free to use. For merchants, the impact is nuanced. Small vendors collecting up to ₹1 lakh per month via UPI are exempt from MDR. Larger merchants, however, will now face a new cost on higher-value transactions. While the government has directed that this cost should not be passed on to customers, some industry experts worry that smaller businesses might try to recover it through pricing or by encouraging cash payments. The move has also faced legal challenges, with the Supreme Court recently issuing a notice to the government to explain the nature of the charge, though it refused to stay its implementation.
