India Moves to End Decade of Free UPI Payments with Merchant Fees

India is preparing to introduce merchant discount rates on Unified Payments Interface (UPI) transactions, a move that could end a decade of free digital payments for businesses. The government is considering a fee of 0.3% to 0.5% on larger transactions at big businesses, while person-to-person payments and small merchant transactions would likely remain free. This shift aims to ensure the financial sustainability of the network, which processed 23.6 billion transactions in July alone, but raises concerns about potential resistance from users and the impact on small merchants.

Launched in 2016, UPI has grown into one of the world's biggest real-time payment networks, with over 550 million users and availability in 11 countries outside India. In the financial year just ended, UPI processed approximately 241.6 billion transactions. The system is run by the National Payments Corporation of India, a non-profit entity, with banks and technology companies like PhonePe and Google Pay providing consumer-facing services.

The government has yet to decide the final rate or exact application of the fees, but proposals under discussion target transactions above 2,000 rupees at larger merchants. Transactions above the proposed threshold account for only about 4% of merchant-payment volumes but roughly 67% of their value, potentially generating up to a billion dollars in new revenue for banks and payment companies.

New research by economists Abhinav Motheram and Sharon Buteau suggests that merchant acceptance is a key driver of UPI growth, and fees could slow expansion if they reach small and informal merchants. A 2024 survey by LocalCircles found that 75% of UPI users said they would stop using the service if transaction fees were introduced.

For years, the government has helped compensate banks and payment firms for providing a service treated as public infrastructure, but the Reserve Bank of India has indicated that someone must pay the operational costs. Brazil's Pix system serves as a comparative model, being free for individuals but permitting low-cost charges for businesses, and is used by more than 140 million people.

Economist Renuka Sane believes the right pricing structure could finally restore commercial sanity to India's digital payment rails, allowing the market to price risk and build a more resilient payments ecosystem. The bigger risk may not be that Indians suddenly abandon UPI because a large retailer is charged a fraction of a percentage point, but that charging merchants makes some of them less enthusiastic about accepting UPI.

The key question is not simply whether UPI should remain free for every merchant transaction, but whether the pricing structure protects the marginal merchants who are still being brought into the digital payments ecosystem. That may be the real test of India's next UPI experiment, as the country figures out how to pay for the system without making it less useful.
