First, A Quick Refresher: What Is MDR?
Merchant Discount Rate, or MDR, is a fee that businesses pay to banks and payment service providers for processing digital transactions. Think of it as a service charge for accepting payments via cards, wallets, or UPI. Since 2020, the government mandated
a zero-MDR policy for UPI and RuPay debit cards to supercharge digital payment adoption. This meant merchants didn't have to pay a fee for accepting UPI payments, which was a huge factor in its nationwide success. However, this also meant that banks and payment companies incurred costs without any revenue from these transactions, raising questions about the long-term sustainability of the ecosystem.
What Is the New UPI Framework?
Effective October 15, 2026, the National Payments Corporation of India (NPCI) has introduced a revised framework. It's not a blanket fee for everyone. Instead, it targets specific Person-to-Merchant (P2M) transactions. Under the new rules, a 0.4% MDR will apply to UPI payments merchants receive that are above ₹2,000. This fee is capped at ₹300 for any single transaction of ₹75,000 or more. Crucially, this charge is for the merchant to bear; it cannot be passed on to the customer. Person-to-Person (P2P) transfers, like sending money to a friend, remain completely free.
The Key Qualification For Small Merchants
Here is the most important part for small businesses: the zero-MDR benefit is not going away, but it now comes with a clear definition. To qualify for zero-fee UPI transactions, a merchant must be classified under the Person-to-Person-Merchant (P2PM) category and receive up to ₹1 lakh per month through UPI QR codes. This special category is designed specifically to protect micro-businesses, street vendors, and neighbourhood kirana stores from these new charges. If a small merchant's monthly UPI collections stay within this ₹1 lakh threshold, they will continue to enjoy zero MDR on all transactions, even on individual payments that are over ₹2,000.
What Happens If You Exceed The Limit?
The rules are designed to be gradual. A small merchant is moved from the protected P2PM category to the standard P2M category only after their monthly UPI collections exceed the ₹1 lakh threshold for three consecutive months. Once re-categorised, they will be subject to the new MDR structure—meaning a 0.4% fee on transactions above ₹2,000. According to government estimates, this change will be surgical. Over 95% of all P2M UPI transactions are below the ₹2,000 mark and will remain free for all merchants anyway. Combined with the small merchant exemption, this means only about 4% of all merchant transactions are expected to be affected by the new MDR.
Why The Change? The Bigger Picture
The introduction of a targeted MDR is a strategic move to ensure the financial health and sustainability of the UPI ecosystem. Processing billions of free transactions puts a significant strain on the infrastructure of banks and payment service providers. The revenue generated from MDR on higher-value transactions will be reinvested into the ecosystem to fund crucial aspects like server capacity, fraud prevention, and cybersecurity. Furthermore, a portion of the MDR collected will be set aside for a dedicated fund to help expand UPI acceptance among more small businesses, especially in Tier-3 to Tier-6 cities and rural areas.
