For six years, the single most repeated fact about UPI has been that it is free. That is about to become a more complicated sentence.
On September 15, 2026, the National Payments Corporation of India published a detailed FAQ setting out a revised Merchant Discount Rate framework for UPI. It takes effect on October 15, 2026, and it ends the zero-MDR regime that has governed UPI merchant payments since January 2020. Within hours, "UPI charges" was trending, and within three days petrol pump associations in Madhya Pradesh had announced they would simply stop accepting UPI payments above ₹2,000 from October 16.
Most of the panic is misdirected. The most important line in the FAQ is the one saying consumers will not pay a rupee. What is actually changing is who funds the rails — and that is a genuinely consequential shift, just not the one people are arguing about on WhatsApp.
What Is MDR, and What Exactly Changed?
Merchant Discount Rate is the fee a business pays for accepting a digital payment. It is deducted from the amount the merchant receives and split among the entities that move the money — the bank that holds the customer's account, the bank that acquires the merchant, the payment service provider and the app.
MDR is not new in India and it is not a tax. Credit cards typically carry 1.5% to 2.5%. Debit card MDR is capped at up to 0.90%. UPI was the exception: since January 2020 it has carried none at all, which is a large part of why it scaled to 24.51 billion transactions worth ₹29.82 lakh crore in August 2026 alone.
What changed on September 15 is narrow. The UPI and Services Steering Committee, chaired by NPCI, introduced a 0.4% MDR on specified person-to-merchant transactions above ₹2,000. Nothing else in the FAQ expands that scope.
The New Rates at a Glance
| Transaction type | MDR from Oct 15, 2026 |
|---|---|
| P2P transfers (any amount) | Nil |
| P2M payments up to ₹2,000 | Nil |
| P2M payments above ₹2,000 (standard) | 0.40%, capped at ₹300 |
| Small P2PM merchants (up to ₹1 lakh/month via QR) | Nil |
| Railways, telecom, insurance, fuel & notified categories | Flat ₹5 per transaction above ₹2,000 |
| Capital markets (mutual funds, broking, securities) | 0.02%, capped at ₹300 |
| Educational institutions | Concessional or capped rates above ₹2,000 |
| Credit-linked UPI (RuPay credit card, credit line on UPI) | Outside this framework — existing credit rules apply |
What It Costs a Merchant: Worked Examples
NPCI's own FAQ gives the arithmetic. Because the cap is ₹300 and the rate is 0.4%, the fee stops growing the moment a payment reaches ₹75,000.
| Payment received | Rate applied | MDR borne by merchant |
|---|---|---|
| ₹2,000 | Nil | ₹0 |
| ₹3,000 | 0.40% | ₹12 |
| ₹50,000 | 0.40% | ₹200 |
| ₹75,000 and above | Capped | ₹300 |
Note the first row. The threshold is above ₹2,000, so a payment of exactly ₹2,000 is free. That detail matters more than it sounds, and we will come back to it.
Will Customers Pay Anything? No — and There Are Two Locks
This is where the confusion has been thickest, so it is worth stating the position precisely. NPCI's FAQ closes the door twice.
Lock 2: Merchants are not permitted to pass MDR on to customers. Consumers pay only the listed price for goods and services.
Scanning a QR code at a shop, a street vendor or a restaurant costs the customer nothing, whatever the bill. Sending money to family or between your own accounts costs nothing. NPCI also used the FAQ to ask users to trust only official updates from the Ministry of Finance, RBI, NPCI and PIB rather than forwarded messages — which tells you how much misinformation was already circulating.
Who Is Actually Exempt?
The exemption that covers the largest number of businesses is the P2PM category — small merchants receiving up to ₹1 lakh per month through UPI QR codes directly into their accounts. They continue at zero MDR, and crucially, GST registration is not required to qualify. Eligibility rests on monthly collection thresholds and merchant categorisation.
That last point answers the most common small-trader worry. Even when a P2PM merchant receives a single payment above ₹2,000, whether MDR applies depends on the merchant's overall categorisation, not on that one transaction crossing a line.
There is also no hardware cost. Existing QR codes keep working; nothing needs replacing or upgrading.
Why Now? The Money Behind the Decision
UPI's problem has never been adoption. It has been that nobody was being paid to run it. Every additional billion transactions added server capacity, fraud-monitoring and customer-support costs to banks and apps with no corresponding revenue line, funded instead by government incentive payouts that have shrunk in recent budgets.
Brokerage estimates put the new revenue pool at roughly ₹15,000–20,600 crore a year for banks and fintechs. How it splits is still being finalised, and analysts differ: Jefferies has modelled roughly 16 basis points to issuing banks, 12 to acquiring banks, 8 to the payer's app and 4 to the PSP bank, while Goldman Sachs projects about half the pool to issuers and PSPs, 30% to acquirers and 20% to apps.
NPCI frames the purpose as technology upgrades, fraud-prevention systems, cybersecurity and long-term sustainability. The framing most likely to survive scrutiny is simpler: an ecosystem that funds itself does not need to keep asking the exchequer for a subsidy.
The Pushback Is Real — and Mostly About One Number
Reaction has split along a predictable line, and the fault line is the ₹2,000 threshold rather than the 0.4%.
CAIT's leadership initially called the framework balanced, arguing most retailers would see limited impact. But traders' bodies have since urged the Centre to reconsider and to keep petrol and diesel outside the net, and CAIT national secretary Shankar Thakkar has warned that retailers will respond by splitting transactions or quietly raising prices on unbranded goods to absorb the cost.
The most concrete response so far came on September 19, when petrol pump associations in Madhya Pradesh said their members would stop accepting UPI payments above ₹2,000 from October 16 — a fuel-station tank fill sits almost exactly at that boundary, and margins there are thin enough that even a flat ₹5 is contested.
SEBI has separately said it will examine concerns raised by stockbrokers about MDR on capital market payments, despite the concessional 0.02% rate.
Underneath all of this is a behavioural question nobody can answer yet. A merchant facing 0.4% above ₹2,000 has three options: absorb it, split the bill into two sub-₹2,000 payments, or steer the customer to cash or a bank transfer. The first is what the framework assumes. The second is trivially easy on UPI. The third is what the last six years of policy were designed to prevent.
What You Should Actually Do Before October 15
If you are a small merchant: check your monthly UPI collections against the ₹1 lakh P2PM threshold and confirm your categorisation with your acquiring bank or payment aggregator. Your QR code does not need to change.
If you are a larger merchant: model your above-₹2,000 ticket mix against 0.4%, and check whether your sector falls into the flat-₹5 or concessional list before assuming the standard rate applies.
The honest summary is that UPI remains free for the people who use it and cheap for the people who accept it — cheaper than any card rail in the country. What ended on September 15 was not free UPI. It was the idea that a payments network handling 24 billion transactions a month could run indefinitely on somebody else's budget.

Rates, thresholds, exemptions and worked examples are drawn from NPCI's FAQ document on MDR for select UPI (P2M) transactions dated September 15, 2026, and the corresponding FAQ published by the Department of Financial Services. Revenue estimates, brokerage split projections, trader reactions and transaction volume data are from reporting by Business Standard, MediaNama, Business Today and Free Press Journal. Operational parameters and category-wise caps are set by the UPI and Services Steering Committee and may be revised before implementation. Last verified: September 19, 2026.
Frequently Asked Questions
Will customers have to pay a fee for UPI from October 15, 2026?
No. NPCI's FAQ states plainly that consumers continue to use UPI free of cost at any transaction value. Apps cannot levy a platform fee, and merchants cannot add MDR as a surcharge on your bill.
What is the new UPI MDR rate?
0.4% on specified person-to-merchant transactions above ₹2,000, capped at ₹300 per transaction. The cap binds from ₹75,000 upwards.
Are P2P transfers affected?
No. Transfers to family, friends and your own accounts remain free for both sender and recipient, at any value.
Which merchants are exempt?
Small merchants under the P2PM framework receiving up to ₹1 lakh per month through UPI QR codes. GST registration is not required to qualify.
How much MDR is payable on a ₹3,000 payment?
₹12, borne by the merchant. A ₹50,000 payment costs ₹200 and anything at or above ₹75,000 costs a flat ₹300.
Do petrol pumps and railways pay 0.4%?
No. Railways, telecom, insurance, fuel and other notified categories pay a flat ₹5 per transaction above ₹2,000 instead of the percentage rate.
Does a RuPay credit card linked to UPI fall under this?
No. Credit-linked UPI payments, including RuPay credit cards on UPI and pre-sanctioned credit lines, sit outside this framework and follow existing credit product guidelines.
Do merchants need new QR codes?
No. Existing QR infrastructure continues to work normally with no replacement or upgrade required.
How much of UPI merchant volume is actually affected?
NPCI says transactions of ₹2,000 or less — which remain free — account for more than 95% of total UPI merchant transaction volume.
