What was announced on September 15

On September 15, 2026, it emerged that a 0.4% merchant fee would apply from October 15 to some customer-to-merchant transfers above 2,000 rupees through the Unified Payments Interface (UPI). For payments of 75,000 rupees or more, the fee is capped at 300 rupees; certain categories carry a fixed fee of 5 rupees.

Transfers between individuals remain free. Exemptions are provided for small merchants, and the published explanations state that shoppers must not face a separate surcharge for paying through UPI. This is an announced rule change with a future effective date, rather than an outcome that has already been measured.

What will change for online stores

For an online store, the fee turns some payments that previously carried a zero rate into a variable acceptance cost. Businesses will have to decide whether to absorb the expense in their margins, change their payment mix or offset it through their overall pricing policy, without charging shoppers directly for UPI.

UPI remains an instant bank-transfer infrastructure operated by NPCI. The sources do not show exactly how the fee will be distributed among banks, apps and payment intermediaries under each contract, so the precise effect on an individual seller depends on its category and order-value profile.

Expert commentary

The change shifts the UPI discussion from transaction-volume growth to the economics of sustainable infrastructure. For the payment system, the fee creates a source of funding for processing, fraud protection and service development. For merchants, the same mechanism becomes a new expense, particularly noticeable in categories with high prices and thin margins.

The impact will be uneven. A store where most purchases fall below 2,000 rupees will barely feel the rule, while an electronics or travel seller will encounter it regularly. An average rate across all transactions is therefore of little use: businesses need to model the fee against the distribution of order values, exemptions and the actual share of UPI payments.

A more explicit price enters the competition among payment methods. Cards, wallets and UPI will be compared on total cost, refund speed and fraud risk as well as conversion. Hidden compensation through overall prices may increase, although the sources rule out passing the fee directly to users.

For customer relationships, how a seller explains the change matters. If UPI remains available without a separate surcharge, shoppers may not notice the new economics at all. If stores start restricting the payment method or reducing discounts without explanation, customers may feel that terms have worsened without disclosure. The sources establish the fee rule, but do not predetermine each seller’s communications or pricing response.

For customers, the main risk is that merchants become less willing to accept UPI for expensive purchases or offer less favorable discounts. An alternative explanation is that predictable revenue will improve the reliability of payment services and competition among them. Both scenarios remain conditional: the rules have yet to take effect, and market behavior has not been observed.

The public outcome is also ambiguous. Free small payments and the exemption for small merchants should limit the impact on financial inclusion, but an amount-based threshold does not account for differences in product margins or between regions. If larger sellers return to cash, payment transparency will decline; if the fee funds sustainable digital acceptance, access may be preserved. The sources do not yet allow a choice between these scenarios.

The effect should be tested after October 15 through UPI’s share of high-value orders, failed payments, changes in conversion, merchants’ acceptance costs, cash use and complaints about hidden surcharges. Initial signals will emerge within a few weeks, but a sustained response is better assessed after the festive season.
