Small businesses across India can breathe a sigh of relief as the government clarifies conditions allowing them to remain exempt from the new Unified Payments Interface (UPI) Merchant Discount Rate (MDR), even for transactions above ₹2,000. While a 0.4% MDR is set to be introduced for select Person-to-Merchant (P2M) transactions from October 15, 2026, a crucial provision safeguards micro-businesses.
Understanding the New UPI MDR Framework
The National Payments Corporation of India (NPCI) is implementing an MDR of 0.4% on UPI P2M transactions exceeding ₹2,000. This move aims to create a sustainable funding model for the rapidly expanding UPI ecosystem, supporting infrastructure, cybersecurity, innovation, and customer service. However, it's vital to distinguish between standard P2M transactions and those under the Person-to-Person-Merchant (P2PM) framework.
Zero MDR Protection for P2PM Small Merchants
The key to continued zero MDR lies in a merchant's classification under the P2PM framework. This category is specifically designed for small vendors who receive UPI QR payments directly into their own bank accounts. To qualify for zero MDR under P2PM, merchants must not exceed a cumulative collection of ₹1 lakh per month through UPI QR transactions.
This means that if a small merchant operating under the P2PM framework receives an individual payment above ₹2,000, they will not automatically incur the MDR charge. The applicability of MDR depends on the overall categorization of the merchant account and their monthly transaction volume, not on single large payments.
How Banks Identify Eligible Small Merchants
Acquiring banks and payment service providers are responsible for monitoring merchants operating under P2PM. Merchants whose inward UPI credits consistently exceed ₹1 lakh per month for three consecutive months will be formally transitioned from the P2PM category to the standard P2M category. Once reclassified, these merchants would then be subject to the 0.4% MDR on transactions above ₹2,000.
Key Clarifications for Small Vendors
- GST Registration: Small merchants are not required to have GST registration to qualify for zero-MDR protection under the P2PM tier. Eligibility is solely determined by the monthly collection threshold and bank account categorization.
- Existing QR Codes: There is no need for small merchants to replace or modify their existing UPI QR infrastructure. Current QR codes, physical stands, and soundboxes will continue to function normally without re-registration.
- Transactions Below ₹2,000: All UPI P2M transactions up to ₹2,000 will remain outside the MDR framework, continuing to be free for both merchants and consumers. These small-value transactions constitute over 95% of total UPI P2M volume.
- Consumer Charges: Consumers will continue to use UPI without paying any transaction charges, regardless of the payment amount or merchant category.
Why MDR is Being Introduced
With UPI processing billions of transactions monthly (e.g., 2,451 crore transactions worth ₹29.9 lakh crore in August 2026), continuous investment in infrastructure, cybersecurity, and innovation is critical. The MDR aims to provide a sustainable funding model for this massive digital payment ecosystem. Even with the new MDR, UPI charges remain significantly lower than traditional card-based payment fees, which typically range from 1.5%-2.5% for credit cards and up to 0.90% for debit cards.
What This Means for Small Shopkeepers
For small vendors covered by the P2PM framework, the message is clear: zero MDR continues as long as they remain within the applicable P2PM classification and their monthly inward UPI payments do not consistently exceed ₹1 lakh. An individual payment above ₹2,000 does not, by itself, trigger MDR for an exempt P2PM merchant. Staying within the ₹1 lakh monthly threshold is the key to maintaining this crucial benefit.
