India’s influential UPI system, which handles nearly half of the world’s real-time transactions, faces a pivotal shift as New Delhi debates levying merchant charges to sustain its rapid growth and infrastructure costs.
India’s Unified Payments Interface, or UPI, has become the emblem of the country’s digital payments boom since its launch in 2016. The system now handles nearly half of the world’s real-time payment transactions, according to the International Monetary Fund, underscoring both its scale and the dependence of millions of users on it. But the question now emerging in New Delhi is whether such a vast public payments network can remain free forever. The Hindu BusinessLine said a provision in the Taxation and Other Laws (Amendment) Bill, 2026, points towards a shift that would allow merchant transaction charges to be levied on some UPI payments.
That debate is not without logic. The newspaper noted that the Centre has been absorbing part of the cost of keeping the system running through incentives for low-value person-to-merchant transactions, while Reserve Bank of India Governor Sanjay Malhotra has said someone must bear the expense of upkeep and investment. Industry data cited by IBEF shows the system’s growth has been extraordinary: in 2025-26, UPI processed about 24,162 crore transactions, up roughly 12,000-fold from its first full year, with annual value rising to nearly ₹314 lakh crore. As usage has scaled up, so too have the demands on NPCI, the body that runs the network, and on the banks and processors that support it.
The proposal under discussion would let the government notify payment systems where merchant discount rate, or MDR, can be charged. Banks would collect the fee from merchants and share it across the payments chain. That would bring UPI closer to the model already used for debit and credit cards, where fees help cover operating costs. The Hindu BusinessLine argued that the current arrangement cannot be sustained indefinitely, especially as banks and payments firms also need a revenue stream to justify their investment.
Still, the article suggested that any fee should be introduced cautiously. It noted that transactions below ₹500 account for 86% of volume, while those between ₹500 and ₹2,000 make up another 10%. If MDR were limited to transactions above ₹2,000, about 96% of person-to-merchant payments would remain exempt, shielding smaller users from added charges. That approach, the paper argued, would preserve affordability for lower-income users while allowing the system to recover costs from larger transactions, where modest fees are less likely to affect behaviour.
Timing, however, may matter as much as design. The Reserve Bank has indicated that UPI’s user base could still double from around 50 crore, while per-user transaction counts remain well below global levels. At the same time, annual growth in both volume and value has slowed from the explosive pace seen in UPI’s early years. For that reason, The Hindu BusinessLine argued that any move to impose MDR should wait until the network reaches a more durable scale.
