GST on UPI Transactions: The Hidden Trap for Small Merchants

If your business is unregistered for the Goods and Services Tax (GST), you will incur an unrecoverable 18% GST on UPI transactions subject to the new 0.4% merchant fee for amounts over ₹2,000. Indian tax law legally restricts input tax credits to registered businesses, making this charge a permanent cost for informal retailers.

Why Can’t Unregistered Merchants Claim Input Tax Credit on UPI Fees?

The government justifies the upcoming 0.4% Merchant Discount Rate (MDR) on UPI payments by pointing to the Input Tax Credit (ITC) mechanism. Officials have stated in press briefings that because merchants can claim back the 18% GST applied to the fee, the tax creates no extra burden on businesses.

However, this assurance is legally inapplicable to India’s smallest retailers. Under Section 22 of the Central Goods and Services Tax (CGST) Act, businesses selling goods with an annual turnover below ₹40 lakh, or services below ₹20 lakh, are exempt from GST registration.

While remaining unregistered is entirely legal, it severs a business from the credit chain. Section 16(1) of the CGST Act clearly states that only a “registered person” is entitled to take credit for input tax charged on services. This creates an absolute statutory barrier against unregistered entities reclaiming these costs. Consequently, millions of unregistered merchants will be forced to absorb the GST on UPI fees as a permanent operational loss.

How Much Will the UPI MDR Fee Actually Cost Small Merchants?

Payment aggregators and banks must levy an 18% GST on their processing fees under the tax code’s SAC Code 9971. Because payment aggregators are required to deduct this statutory tax at the source before settling funds, the effective deduction for merchants unable to claim credit rises from 0.40% to 0.472%.

Transaction Amount	Base MDR (0.4%)	GST on Fee (18%)	Total Deduction	Net Settlement
₹2,500	₹10.00	₹1.80	₹11.80	₹2,488.20
₹5,000	₹20.00	₹3.60	₹23.60	₹4,976.40
₹10,000	₹40.00	₹7.20	₹47.20	₹9,952.80

Aggregators cannot waive a statutory tax for unregistered entities. The nominal 0.4% MDR incurs an 18% GST, adding 0.072% to the total deduction regardless of the merchant’s GSTIN status.

Are GST Composition Scheme Dealers Exempt from the UPI Tax?

No. The 1.5 million Indian businesses registered under the GST Composition Scheme are explicitly prohibited by Section 10(4) of the CGST Act from claiming any input tax credit. The inability to recover this tax extends directly from the informal sector into formally registered small businesses.

The GST Council offers the Composition Scheme for businesses with a turnover up to ₹1.5 crore, allowing them to pay a flat tax rate—usually 1% or 5%—instead of filing complex monthly returns. Despite participating in the formal tax system, these dealers pay the 18% GST on their UPI fees directly out of their gross margins.

How Many Merchants Will Absorb the UPI GST Burden?

Comparing national payment infrastructure against tax registries reveals that the vast majority of physical endpoints accepting digital payments belong to entities outside the formal ITC network.

While official policy aims to protect daily micro-purchases at local markets and street vendors, data from the National Payments Corporation of India (NPCI) shows that the total number of active merchant UPI QR codes vastly exceeds the roughly 1.4 crore active GST registrations reported by the Goods and Services Tax Network (GSTN). The tax-offset mechanism cited by the Finance Ministry covers only a fraction of the merchants required to pay the fee.

Why Did the Finance Ministry Assume GST Would Not Burden Merchants?

When drafting the new UPI fee structure, policymakers modeled the tax flow on traditional card interchange systems—the backend networks where banks exchange transaction data and fees. Before the zero-MDR mandate for UPI, point-of-sale card terminals were predominantly deployed by formal corporate retailers who could naturally offset business-to-business tax debits.

The Ministry maintains that the UPI transaction limit of ₹2,000 specifically excludes micro-purchases. Officials argue that retailers consistently processing larger single tickets generate substantial turnover and should integrate into the formal tax system. Furthermore, the 0.4% base fee remains significantly lower than global credit card MDRs, which typically range from 1.5% to 2.5%.

How Are Retailers Bypassing the ₹2,000 UPI Transaction Limit?

To avoid the unrecoverable 0.472% hit on higher-value sales, unregistered micro-merchants and consumers are actively restructuring how they accept payments. Merchants indicate two primary workarounds for bills exceeding the limit.

The first is transaction splitting. For a ₹3,500 repair bill, a vendor asks the customer to scan the QR code twice, authorizing one payment for ₹1,900 and a second for ₹1,600, keeping both under the fee threshold.

The second approach is a direct cash discount. By offering a ₹15 reduction on a ₹3,000 purchase if paid in cash rather than UPI, the merchant spends less than the ₹14.16 fee deduction, retaining the difference while avoiding the tax leakage entirely.

Frequently Asked Questions

Do I pay GST on UPI transactions if I don’t have a GST number?
Yes. Payment aggregators deduct an 18% GST at the source on all MDR fees regardless of your registration status. Under Section 16(1) of the CGST Act, you cannot claim this tax back without a GST registration.

What is the actual deduction rate for merchants who cannot claim ITC?
For unregistered merchants and composition dealers, the 18% GST on the 0.4% base fee acts as an unrecoverable surcharge. This raises the effective cost of accepting UPI payments over ₹2,000 from 0.40% to 0.472%.

Can a GST Composition Scheme dealer claim Input Tax Credit on UPI fees?
No. While composition dealers are formally registered taxpayers, Section 10(4) of the CGST Act explicitly prohibits them from claiming any input tax credit. They must absorb the GST applied to their UPI merchant charges.
