Government Imposes 18% GST on UPI Merchant Discount Rate; Merchants Can Claim ITC

From October 15, 2026, select person-to-merchant UPI payments will attract a 0.4% MDR on transactions above ₹2,000, and an 18% GST will apply to that MDR. GST-registered merchants can claim the GST component as input tax credit where eligible.

Useful takeaways from this story.

GST paid on MDR is claimable as input tax credit (ITC) by GST-registered merchants, subject to usual ITC eligibility rules.

Other fee structures — a flat ₹5 on specified transactions and the ₹300 cap on MDR — will also have 18% GST applied to the fee component where MDR/fees are chargeable.

A government decision makes merchant discount rate (MDR) charges on certain UPI person-to-merchant (P2M) payments subject to 18% GST. The tax applies only to the MDR or fee actually levied on eligible UPI transactions — not to the whole payment amount.

How the charge works — a concrete example If a merchant receives a ₹10,000 UPI payment and MDR of 0.4% is applied, the MDR equals ₹40. An 18% GST on that ₹40 is ₹7.20. The merchant's total transaction cost becomes ₹47.20. The GST is calculated only on the ₹40 fee, not on the ₹10,000 sale value.

A flat fee of ₹5 that applies to specified transactions (for example, certain railway payments) will also attract 18% GST on that fee amount. Where the MDR cap of ₹300 applies, GST will be levied on the applicable MDR amount in line with the rules. These are procedural applications of GST to the fee component.

How this aligns with existing practice Credit and debit card MDRs already attract 18% GST because card processing fees are treated as taxable services. The government says the same tax treatment will now apply to eligible UPI transaction fees.

  • Check whether your business is GST-registered and whether your outward supplies make you eligible to claim ITC. If eligible, you can offset the GST on MDR through the normal ITC route.
  • For businesses with exempt supplies, plan for the MDR GST to be a potential cost. Review pricing and margins where MDR applies.
  • Monitor applied MDR and fee amounts (0.4% above ₹2,000, flat ₹5 where specified, and the ₹300 cap) to calculate cash flow and tax credits accurately.

UPI transaction exemptions continue as before. The change only adds GST to the fee component where an MDR or specified charge is levied.

From October 15, 2026, eligible UPI merchant-facing fees will be taxable at 18%, but GST-registered merchants can generally recover that tax through ITC when their supplies permit recovery. Merchants whose supplies are exempt should account for this as an added cost.
