India's digital payments landscape stands at a historic crossroads. The Lok Sabha has passed the Taxation and Other Laws (Amendment) Bill, 2026, fundamentally altering the regulatory framework that has governed Unified Payments Interface (UPI) transactions since January 2020. This legislation amends Section 10A of the Payment and Settlement Systems Act (PSSA), 2007, removing the blanket prohibition on banks and payment service providers (PSPs) from levying charges on electronic payments. The shift from a fixed list of prescribed modes under Section 269SU of the Income-tax Act to a flexible government-notification model represents one of the most significant policy changes in India's fintech history.
The amendment replaces the rigid reference to Section 269SU-mandated electronic modes with broader language empowering the central government to specify which payment methods may attract charges through notification. This legislative flexibility enables a tiered pricing structure that protects small merchants and low-value transactions while allowing cost recovery from large merchants and high-value payments. The government's approach emphasizes a "small charge" model designed to balance financial sustainability with affordability, particularly for vulnerable segments.
The causal relationship between UPI's explosive growth and the banking sector's push for MDR authorization is rooted in simple mathematics.
Transaction value climbed from ₹7,000 crore to ₹314 lakh crore over the same period. Today, UPI accounts for 81% of retail payment transactions by volume and 49% of global real-time payment transactions.
But this success comes at a staggering cost.
The government's incentive scheme allocated only ₹1,500 crore for FY25—down from ₹3,500 crore in FY24—covering merely 11% of industry costs. Banks and PSPs have absorbed these losses through cross-subsidization, but this model is fundamentally unsustainable. A modest 0.1% MDR on UPI's FY2025 value would generate approximately USD 3.1 billion (₹26,000 crore) annually, creating a viable revenue stream for infrastructure investment.
The proposed MDR structure targets merchants with annual turnover above ₹50 crore, with rates ranging from 0.3% to 0.6% on transactions exceeding ₹2,000. This approach protects 96% of person-to-merchant transactions by volume while capturing 67% of transaction value where merchants have greater ability to pay. Large retailers like Amazon and Flipkart already pay 1-3% MDR on credit cards and up to 0.9% on other debit cards, so aligning UPI costs with existing payment channel expenses eliminates a structural subsidy funded by banks and PSPs.
This cautious stance reflects the central bank's methodical evaluation of payment infrastructure cost recovery mechanisms.
The RBI's perspective is shaped by several causal factors driving the need for sustainable funding models. First, the sheer scale of UPI operations—23 billion transactions worth ₹29.9 lakh crore in July 2026 alone—requires massive ongoing investment in authorization systems, settlement infrastructure, cybersecurity, fraud detection, cloud storage, and network monitoring. Second, the current subsidy model creates long-term vulnerability, as evidenced by declining government allocations from ₹3,500 crore in FY24 to ₹427 crore in recent budget estimates. Third, international experience shows that sustainable payment systems require predictable revenue streams for continuous innovation and resilience.
If the Union government exercises its new notification power, the RBI's regulatory oversight will likely evolve toward more sophisticated pricing supervision, enhanced consumer protection mechanisms, and data-driven monitoring of payment system health. The central bank may develop frameworks for MDR rate reasonableness, transparency requirements for fee disclosure, and systems for monitoring competitive neutrality across payment channels.
For small businesses, the proposed MDR structure offers significant protection. Merchants with annual turnover up to ₹1.5 crore remain exempt from MDR, while the government continues its incentive scheme reimbursing up to 0.15% for transactions up to ₹2,000. This targeted approach shields the kirana stores and micro-merchants where UPI has been most transformative.
However, businesses near the threshold face competitive pressures. For a typical business with 10% net margins, even a 0.3% MDR consumes 30% of profit on each transaction. The margin equation becomes particularly acute for low-ticket, high-volume businesses where processing fees represent a substantial portion of earnings. Yet the government's incentive scheme—budgeted at ₹2,000 crore for 2026-27—provides a buffer for small merchants, maintaining the accessibility that has driven UPI's remarkable adoption.
Merchant adoption dynamics will be influenced by strong consumer resistance to fees.
This resistance creates pressure on merchants to absorb costs rather than pass them to consumers, potentially affecting adoption rates among price-sensitive segments.
Payment service providers will fundamentally restructure their pricing strategies and revenue models in response to MDR authorization. The current zero-MDR regime has forced PSPs to rely on platform fees, SaaS subscriptions, and value-added services rather than transaction-based revenue. With MDR authorization, PSPs can implement tiered pricing structures that align with merchant capabilities and transaction values.
The competitive landscape will favor PSPs that can balance MDR implementation with customer retention. Bank-affiliated PSPs like HDFC Bank, ICICI Bank, and Axis Bank leverage their infrastructure ownership and regulatory relationships to offer bundled pricing combining payment services with banking products. Fintech PSPs like Razorpay and PayU compete through technology leadership, superior APIs, and transparent total cost of ownership models. Consumer app PSPs like PhonePe and Paytm utilize their massive user bases and merchant networks to maintain adoption through ecosystem integration and value-added services.
Payment infrastructure firms will realign investment priorities toward technology modernization, geographic expansion, and product innovation. New revenue streams from MDR will enable investments in AI-powered fraud detection, smart routing technology, instant settlement infrastructure, and cross-border capabilities. The industry estimates that even a 0.25% MDR on eligible UPI transactions could generate approximately ₹13,000 crore in annual revenue, funding the next phase of India's digital payments evolution.
The Union government's amendment represents a sophisticated policy balancing act between promoting digital payments and ensuring sustainable revenue models. The zero-MDR policy delivered remarkable inclusion benefits—exponential growth in vendor adoption, especially in semi-urban and rural areas; integration of low-income segments into the formal financial system; and significant contributions to economic formalization and tax compliance. However, the sustainability imperative cannot be ignored. RBI Governor Malhotra emphasized that UPI "cannot be free indefinitely" given the substantial operational costs required for smooth system operation.
Global comparative analysis supports a differentiated hybrid funding model. Brazil's Pix system charges business fees while keeping individual transactions free. Singapore's PayNow imposes fees selectively while preserving widespread adoption. The UK's Faster Payment System charges monthly connectivity and per-transaction fees to cover infrastructure costs. These international examples demonstrate that nominal charges on commercial users can coexist with free consumer access, creating stable revenue streams for infrastructure development while maintaining adoption momentum.
The government's notification power to specify chargeable electronic modes introduces both flexibility and uncertainty. On one hand, it enables adaptive, targeted policy implementation that can respond to market developments and technological changes. On the other hand, it creates predictability challenges for business planning and cost forecasting. The success of this balanced approach will depend on robust safeguard mechanisms including transparent notification processes, stakeholder consultation, gradual implementation, and periodic review of effectiveness.
India's digital payments revolution has achieved what many thought impossible—becoming the world's largest real-time payment system by volume while driving unprecedented financial inclusion. The challenge now is building a financially sustainable foundation that preserves these gains while enabling continued innovation. The MDR authorization represents not an end to this journey, but a necessary evolution toward a mature, self-sustaining digital payments ecosystem that can serve India's 1.4 billion citizens for decades to come.
