GST on UPI MDR: 18% Tax + ITC Rules, Now After Diwali

Search "GST on UPI" and you'll land on two contradictory-looking sets of headlines: the Finance Ministry calling GST-on-UPI reports "false and baseless" as recently as 8 August 2026, and a wave of tax-press coverage from 16–17 September 2026 saying an 18% GST will in fact apply from 15 October 2026, a start since deferred to after Diwali (see the 14 October update below). Both are true, because they're answering different questions. This post is about the second one — the GST and input tax credit mechanics on the new UPI Merchant Discount Rate (MDR) — with worked examples across transaction sizes and the ITC gap that catches unregistered and small-turnover merchants off guard.

If you haven't yet read up on the MDR change itself — who pays the 0.4%, what stays free, and the sector-specific exceptions — our companion piece, MDR on UPI Is Back: The New 0.4% Charge From 15 October 2026, Explained, covers that in full. This one assumes you know the basics and goes straight into the tax side.

This reflects NPCI's 15 September 2026 circular (official) for the MDR structure, CBIC official statements reported in the press on 16–17 September 2026 for the GST/ITC treatment, and NPCI's own clarification of 22–23 September 2026. The GST treatment still hasn't been issued as a standalone GST Council notification. All of this is current as of 25 September 2026, apart from the 8 October update below. Confirm the final position with your CA before filing, especially close to the rollout.

Update, 8 October 2026. The 57th GST Council met on 8 October. Finance Minister Nirmala Sitharaman said there was no MDR-related discussion at the meeting, as reported by Business Today, so the Council did not change the 18% GST on the fee. It is still not a standalone notification, so the position below is unchanged. At that date, NPCI's circular still set the MDR start at 15 October.

14 October: the start date has changed. As reported on 13 October, NPCI's steering committee deferred the 0.4% MDR to immediately after Diwali, on a date to be notified, so 15 October is no longer the start date in those reports. The 18% GST on the fee, the rates and the ₹2,000 threshold below are not described as changed. See the latest on the postponement.

Latest update (25 September 2026): NPCI says most merchants won't feel it

On 22 September 2026, and again in a post on X on 23 September, NPCI pushed back on claims that GST on the UPI MDR "will burden small merchants." Two points from that clarification matter here:

1. More than 96% of UPI merchant transactions are ₹2,000 or less. Those payments carry no MDR, so there's no GST on MDR either. Note what this figure measures: it's the share of merchant transactions by number, not by rupee value. A shop whose sales are mostly small-ticket UPI payments will barely notice the change. A business with fewer, larger bills — electronics, furniture, B2B supplies — sits in the other 4% more often, and that's where the fee lands. NPCI also restated that small merchants receiving up to ₹1 lakh a month through UPI stay at zero MDR under the P2PM framework.

2. NPCI's own framing of the ITC set-off. NPCI said GST paid on MDR "will be adjusted against the GST payable" on the merchant's sales, the same way any input tax is set off against output tax. Its worked example is the same one this post uses below: ₹40 MDR on a ₹10,000 payment, ₹7.20 GST on that fee, claimable as input tax credit. That's a useful, citable confirmation of the mechanics from the payments body itself, not just from tax-press sources.

The catch is in NPCI's own wording: the offset works for merchants eligible to claim and use input tax credit. The groups this post flags below — unregistered merchants, composition taxpayers, and businesses making exempt supplies — are not covered by that reassurance. For them the GST on MDR is still a straight cost. Nothing in the clarification changes the rates, the ₹2,000 threshold, the ₹300 cap, or the 15 October start date the circular originally set.

What actually changes when the MDR starts, in brief

Per NPCI's circular:

• 0.4% MDR on UPI person-to-merchant (P2M) payments above ₹2,000, capped at ₹300 per transaction (the cap kicks in at ₹75,000).
• UPI payments of ₹2,000 or below, and all P2P transfers, stay free — no MDR, no GST, at any value.
• Small merchants under the P2PM framework, receiving up to ₹1 lakh a month through a UPI QR code, pay zero MDR regardless of individual transaction size — until they cross that threshold for three consecutive months.
• Railways, telecom, insurance and fuel get a flat ₹5 instead of 0.4%; capital-market payments get 0.02%, capped at ₹300.

None of that is new information if you've read the companion post — it's the backdrop for everything below.

GST applies to the fee, not your sale — and that's the whole source of the confusion

This is the distinction that the "false and baseless" headlines and the "18% GST" headlines are both actually agreeing on, once you separate the two things being taxed. NPCI's 22 September clarification says the same thing in plain terms: on a ₹10,000 payment, the 18% GST applies only to the ₹40 fee, not to the ₹10,000.

1. GST on your underlying sale — the tax on whatever you sold the customer (goods or a service), charged at whatever rate your HSN/SAC code carries. This is completely unaffected by any of this. A ₹10,000 sale that carried 18% GST before 15 October still carries 18% GST after it. The Finance Ministry's repeated denials — that there's no GST being newly imposed on UPI transactions — are correct and are about this.
2. GST on the MDR itself — the 0.4% fee is payment for a service (processing and settling the digital payment), supplied to you by your bank, PSP, or aggregator. Like any other service, it attracts GST — 18%, the standard rate for financial and payment-processing services. This is the new cost, and it's what the September 2026 coverage is about.

So both claims are true at once: no new tax on the sale you make, but a real, new 18% tax on the fee your bank charges you for processing that sale digitally above ₹2,000. Nothing about your invoice to the customer changes. What changes is a line item on your settlement statement that didn't carry a tax before, because the fee itself didn't exist before.

Worked examples: ₹2,500, ₹10,000, ₹50,000

Same no-concessional-category retail sale, paid by UPI, at three different sizes — a small ticket just past the ₹2,000 free threshold, a mid-size sale, and a larger one:

The customer pays the same sale value either way and gets an invoice at whatever GST rate their purchase carries — that part is untouched at every size. What changes is purely the settlement deduction: on the ₹2,500 sale it's ₹11.80 (a sale just ₹500 over the free threshold still pulls the full MDR-plus-GST hit), and it scales linearly up to ₹236.00 on the ₹50,000 sale. Run the same math on a ₹75,000+ sale and the MDR caps at ₹300, so GST on it caps too — a flat ₹54, for a total deduction of ₹354 regardless of how much larger the sale gets.

Who can actually claim input tax credit

This is the part that most coverage glosses over: ITC on the ₹7.20 isn't automatic, and it isn't available to everyone paying it.

You can generally claim it if:

• You're GST-registered, and
• The UPI collection this MDR was deducted from relates to a taxable outward supply (i.e., you're making sales that themselves attract GST, not exempt or nil-rated ones), and
• You meet the ordinary Section 16 conditions for any ITC claim — you hold a valid tax invoice or debit note for the MDR-and-GST charge, the service has actually been supplied to you, the tax has actually reached the government, you've filed your return, and the credit shows up matched in your GSTR-2B.

You generally can't — or can't claim it in full — if:

• You're not GST-registered at all (below the registration threshold and haven't opted in voluntarily). You still pay the 18% GST on the MDR — it's baked into the deduction whether or not you're registered — but with no GSTIN, there's no mechanism to claim it back. It's a straight cost.
• You deal in exempt or nil-rated supplies (common in healthcare, education, and some agricultural trade) — GST paid on inputs used for exempt supplies generally can't be credited, and MDR-on-UPI is no exception.
• You're on the Composition Scheme — composition taxpayers don't take ITC at all under the scheme's design, on this or anything else. If you're weighing whether composition still makes sense once this fee starts, our GST Composition Scheme explainer covers the rates, limits and how to compare it with regular GST.

The documentation problem

Unlike a GST-registered vendor invoice you receive and file away, the MDR-and-GST deduction here is typically netted off automatically inside your settlement — you don't get handed a separate tax invoice at the point of each transaction the way you would for, say, an aggregator's monthly platform-fee invoice. To actually claim the credit, you need your bank, PSP, or acquiring aggregator to issue a proper GST-compliant tax invoice or a consolidated monthly statement itemising the MDR and the GST charged on it — the same way banks already issue GST invoices today for other chargeable services (demand drafts, certain account charges, POS terminal rental). Ask for this explicitly if your current settlement report only shows a single blended deduction line; without an itemised, GSTIN-linked document from the deductor, there's nothing to match against your GSTR-2B, and the credit is at risk of being disallowed on review even if you were otherwise eligible.

The gap: crossing the UPI threshold without crossing the GST threshold

Here's the scenario the outline for this piece specifically wanted to nail down, because it's a real and fairly common gap, not an edge case.

GST registration is currently mandatory once your aggregate turnover crosses ₹40 lakh a year for goods (₹20 lakh in special-category states) or ₹20 lakh a year for services (₹10 lakh in special-category states) — with several situations (inter-state supply, selling through an e-commerce operator, and a few others) requiring registration regardless of turnover.

The UPI small-merchant carve-out, separately, is based on ₹1 lakh a month in UPI QR receipts — which annualises to ₹12 lakh a year. Do the comparison:

• A merchant doing ₹12 lakh a year through UPI crosses the P2PM zero-MDR threshold (after three consecutive months over ₹1 lakh) and starts paying 0.4% MDR + 18% GST on it — while sitting comfortably under both GST registration thresholds (₹40 lakh goods / ₹20 lakh services), and therefore likely unregistered.
• That merchant now pays real money on every UPI sale above ₹2,000, with no way to claim it back, because they have no GSTIN. A GST-registered competitor doing the identical volume nets the GST portion out through ITC; this merchant absorbs all of it as cost.

This is the group worth flagging specifically if you run or advise a small business near that ₹1 lakh/month UPI mark: crossing the UPI threshold has a tax consequence that crossing the GST threshold would normally offset, and for a while — potentially indefinitely, if turnover stays under ₹20–40 lakh — it doesn't. The two thresholds aren't aligned, and nothing about the NPCI circular or the GST treatment closes that gap; it's simply a byproduct of two separate rules that were never designed against each other.

The flip side is also worth knowing: if you're already voluntarily GST-registered specifically to serve B2B customers who need input credit from you, this MDR change is one more reason that registration continues to pay for itself — you get the ITC on the MDR too, on top of whatever else drove the decision to register.

Recording it in your books

Because the deduction is typically netted inside settlement rather than paid separately, it's easy to under-record: many small businesses simply book the net settlement amount as the sale, which understates both revenue and the input credit you're entitled to. The cleaner treatment:

1. Record the full sale value as revenue/receivable at the time of sale — same as you always would, regardless of payment mode.
2. Book the MDR as a separate expense (a bank charges / finance cost line), and the GST on it as input tax credit receivable, not folded into the expense — only do this if you're actually eligible to claim it per the section above; if you're not, the full ₹47.20 is expense, not a partial credit.
3. Reconcile monthly against the itemised statement or tax invoice from your bank/aggregator, not just the net figure that hit your account — this is also your audit trail if the ITC claim is ever questioned.

On the ₹10,000 example above, for a registered merchant able to claim the credit, the entries would be:

If you're not eligible to claim the credit, the ₹7.20 simply folds into the MDR expense line instead of sitting in a receivable account — the total deduction is identical either way; only where it lands in your books changes.

Our UPI MDR & GST Calculator does this whole chain for you — MDR, GST on it, net settlement, and whether you can actually claim the ITC — for any merchant category and transaction size, rather than working through the 18%-of-0.4% math by hand each time. Our GST Invoice Generator can help separately if you're issuing your own debit notes to reconcile aggregator charges.

What's actually confirmed versus still pending

Keep these two tracks separate, because they carry different levels of certainty:

Confirmed, via an official NPCI circular dated 15 September 2026:

• The 0.4% MDR structure, the ₹2,000 threshold, the ₹300 cap, the P2P exclusion, and the ₹1 lakh/month small-merchant carve-out.
• Effective date: 15 October 2026 per the circular; reported on 13 October as deferred to immediately after Diwali, date to be notified.

Restated by NPCI itself, 22–23 September 2026:

• More than 96% of UPI merchant transactions (by number) are ₹2,000 or less, and so carry no MDR and no GST on MDR.
• GST paid on MDR can be set off against output GST by merchants eligible to claim and use ITC.

Reported via CBIC-official statements to the press, not yet a standalone notification as of this writing:

• The specific application of 18% GST to the MDR fee, and the ITC eligibility mechanics described above. This follows from applying the existing GST rate on financial/payment-processing services to a newly created fee, rather than a brand-new tax rule — but at least one report noted any remaining ambiguity could be taken up separately by the GST Council.
• The 57th GST Council meeting (8 October 2026) did not take this up. The Finance Minister said there was no MDR-related discussion, so the Council has not clarified or changed the 18% GST on the fee. What it did decide is covered in 57th GST Council Decisions (8 Oct 2026): ITC, Arrest Powers.

Why the "false and baseless" headlines aren't a contradiction: those denials, most recently on 8 August 2026, predate NPCI's 15 September 2026 circular and were responding to a different, broader claim — that GST would apply to UPI transactions themselves, or that MDR would be reintroduced at all. Both of those, taken literally, remained false right up until the circular that actually introduced the MDR. Once the MDR itself became real, GST following it — on the fee, not the transaction — is just ordinary tax law applying to a new taxable service, which is a narrower and different claim than what was being denied.

What to do before the MDR starts

1. Work out if this touches you at all — sales at or below ₹2,000, and small P2PM merchants under ₹1 lakh/month, see no MDR and therefore no GST on it either.
2. Check your GST registration status against your UPI volume, specifically if you're doing more than ₹1 lakh/month through UPI but sit under the GST registration threshold — you're in the gap described above, paying the GST with no way to claim it back.
3. Ask your bank, PSP, or aggregator now for an itemised, GSTIN-linked tax invoice or monthly statement covering MDR and the GST on it — don't wait until filing season to discover your settlement reports only show a blended figure.
4. Update your bookkeeping to record the gross sale value and the MDR/GST deduction separately, rather than just the net settlement amount, so the ITC (if you're eligible) is actually traceable.
5. Re-check this after the rollout itself. The 57th GST Council meeting on 8 October did not discuss MDR, so treat the GST/ITC mechanics above as the current official-source-backed position, not a locked notification.

The bottom line

Nothing changes about the GST on what you sell. What changes is that the fee your bank charges you for processing a UPI sale above ₹2,000 — new once the MDR starts — carries its own 18% GST, the same as most services do, and registered merchants making taxable supplies can generally claim that back as input tax credit provided they get proper documentation from whoever deducted it. Unregistered merchants and those under composition or dealing in exempt supplies pay it as a flat cost with no offset. If your UPI receipts are anywhere near ₹1 lakh a month, work out which side of that gap you're on before the rollout, not after.
