UPI MDR 2026: Rates, GST Rules & Business Impact Explained 

For six years, UPI has settled money instantly and for free, on both sides of the transaction. That changes from October 15, 2026. NPCI has confirmed a 0.4% MDR on specified UPI merchant payments above ₹2,000, ending the zero-charge era that began in 2020. If you run a retail store, a trading business, or any operation that takes UPI payments over the counter, this is the first change to your payment costs in years — and it touches your books in ways the news coverage isn’t spelling out.

Quick answer: From October 15, 2026, merchants pay a 0.4% MDR on UPI transactions above ₹2,000 (capped at ₹300 for payments over ₹75,000). Specified sectors like fuel and agri-inputs pay a flat ₹5 instead. Customer-to-customer transfers remain free, and small merchants processing under ₹1 lakh a month via QR code are exempt. GST is expected to apply to the MDR amount itself, not to the transaction value.

What Exactly Is Changing

UPI launched in 2016 with nominal fees, but by January 2020 the government moved to a zero-MDR model to accelerate digital payment adoption. That worked — UPI now processes over 24 billion transactions a month across more than 550 million users. But a zero-revenue model isn’t free to run. A Parliamentary Standing Committee on Finance has flagged that existing government incentives don’t fully cover the ecosystem’s operating costs. The new MDR is the government’s answer: a targeted fee that keeps everyday and small-ticket UPI use free while asking higher-value merchant transactions to contribute toward upkeep.

NPCI has been explicit that merchants cannot pass this fee on to customers, so your invoice amount and your customer’s payment amount stay the same. What changes is what actually lands in your bank account.

What the fee looks like in practice:

Does GST Apply to the New MDR?

This is the question your accountant is going to ask you, and it’s worth getting ahead of it. In 2025, when UPI still ran on zero MDR, the Finance Ministry stated plainly that since no MDR was charged, there was consequently no GST applicable to UPI transactions. That logic runs the other way now that MDR exists again. GST on payment processing fees — the kind already charged on card transactions and other digital instruments — is typically levied at 18%, charged on the fee itself rather than on the underlying transaction value.

So the reasonable expectation is that the new UPI MDR will follow the same pattern: GST applied to the 0.4% fee, not to your ₹5,000 sale. That said, this is a new framework, and the CBIC has not issued a dedicated notification specific to UPI MDR as of this writing. Don’t file returns based on assumption — confirm the applicable rate with your CA once formal guidance is published.

The Part That Actually Affects Your Books

Here’s where this stops being a news story and starts being a bookkeeping task. Three things change in your day-to-day accounting:

1. MDR becomes a recordable expense. Every UPI settlement above ₹2,000 now needs a corresponding entry for the fee deducted, typically booked under bank charges or payment processing costs, separate from your revenue line.
2. Settlement amounts stop matching invoice amounts. If you raise an invoice for ₹5,000, the amount that hits your account will be ₹4,980 (or less, once GST on the fee is factored in) — not ₹5,000 flat. If your reconciliation process assumes a 1:1 match between invoice and bank credit, it will start throwing mismatches every single day.
3. Margins on high-ticket UPI sales tighten slightly. For retailers and traders doing volume business in electronics, apparel, or wholesale goods, where individual transactions regularly cross ₹2,000, this is worth factoring into pricing conversations — even at 0.4%, it adds up over a month of transactions.

Before October 15: A Quick Checklist

• Talk to your CA about GST treatment once CBIC guidance is out, so your first post-October invoices are coded correctly from day one.
• Update your bookkeeping categories now to include a “UPI MDR / payment processing charges” line, rather than lumping it into general bank charges later.
• Flag high-ticket product lines where MDR will apply most often, and decide if pricing needs a small adjustment to protect margin.
• Check if your business falls under a specified sector (fuel, agri-inputs, telecom, insurance) — your MDR treatment is flat-rate, not percentage-based, and different accounting logic applies.
• Brief your billing/counter staff so they don’t mistakenly tell customers they’ll be charged extra — NPCI has been clear the MDR isn’t passed on to the payer.

How Elixir Books Handles This

Elixir Books keeps your bank feed, invoicing, and GST-aware ledgers connected, so a settlement that’s short by the MDR amount gets flagged and categorised automatically instead of sitting as an unexplained variance. For retailers and traders taking regular UPI payments above the ₹2,000 threshold, that means your books stay accurate without someone manually tracing every fee deduction back to its source invoice.

If you’re setting this up for the first time, our guide on GST-ready billing for retail businesses and our breakdown of how integrated finance cuts reconciliation errors cover the underlying workflow this change plugs into. If you’re still finalising your e-invoicing setup, our e-invoicing guide for small businesses is a good next read.

Frequently Asked Questions

When does the new UPI MDR come into effect?

October 15, 2026, for specified person-to-merchant transactions above ₹2,000.

Will customers be charged extra for paying via UPI?

No. NPCI has stated merchants cannot pass the MDR on to customers. Person-to-person UPI transfers remain free regardless of amount.

Are all merchant sectors charged the same MDR?

No. Most sectors pay 0.4% (capped at ₹300), but railways, telecom, insurance, fuel, and agri-inputs pay a flat ₹5, and capital-market transactions pay 0.02% capped at ₹300.

Are small shopkeepers affected?

Micro-merchants processing under ₹1 lakh a month via UPI QR codes are exempt from the new MDR.

How should I record the MDR fee in my books?

Book it as a payment processing or bank charge expense, separate from revenue, and reconcile it against each affected settlement rather than netting it off in bulk at month-end.

Does the ₹2,000 threshold affect my daily UPI transaction limit?

No — this is a separate rule from UPI’s transaction limits. It only determines when MDR applies.
