Credit Card Surcharge by Merchants: Legal or Not in India?

Bottom Line: Merchants in India are not supposed to pass on the MDR (Merchant Discount Rate) to you as a surcharge. The cost of accepting card payments is the merchant’s to bear — if a shopkeeper slaps 2% extra on your bill for swiping your credit card, you have every right to push back and report them.

The 2% Tax That Shouldn’t Exist

You’ve been there. You pick out a ₹15,000 jacket, tap your HDFC Infinia at the counter, and the shopkeeper says: “Card pe 2% extra lagega.”

It happens at electronics stores in Nehru Place, jewellers in T Nagar, even at some dentist clinics. The merchant treats the card processing fee as your problem. But is it actually legal?

Let’s break it down.

What Is MDR and Who’s Supposed to Pay It?

MDR — Merchant Discount Rate — is the fee that payment networks (Visa, Mastercard, RuPay) and acquiring banks charge the merchant for processing a card transaction. It typically ranges from 1% to 2.5% depending on the card type and merchant category.

Component	What It Is	Who Pays
MDR (Merchant Discount Rate)	Fee for processing the card payment	Merchant
Interchange Fee	Portion of MDR that goes to the card-issuing bank	Merchant (indirectly)
Surcharge on customer	Extra amount added to the bill for card use	Should not be charged
Convenience Fee	Legitimate fee for offering an alternative payment channel (e.g., online booking)	Customer (when disclosed upfront)

The key distinction: MDR is a cost of doing business for the merchant, just like rent or electricity. Passing it to you is like a restaurant charging you extra for using their plates.

What Do RBI Rules Actually Say?

Here’s where it gets nuanced. The RBI’s Master Direction on Card Acceptance Infrastructure (2021, updated 2024) requires:

Transparency: Any charges applied to card transactions must be clearly disclosed before the transaction.
Card network agreements: Visa and Mastercard’s merchant agreements explicitly prohibit merchants from adding surcharges to card transactions in India. When a merchant signs up for a POS terminal, they agree to absorb the MDR.
GST treatment: The government removed GST on MDR for debit card transactions up to ₹2,000 (post-2020 budget). For credit cards, GST on MDR still applies — but again, to the merchant, not you.

The Grey Area: Convenience Fees

There’s one exception merchants love to exploit. Convenience fees are technically permitted when:

The merchant offers an alternative payment channel (e.g., paying utility bills online instead of in person)
The fee is disclosed before you initiate the transaction
It’s a flat, reasonable amount — not a percentage that mirrors MDR

So when IRCTC charges you a convenience fee for booking train tickets online, that’s technically permissible. But when a local shop charges you 2% just for tapping your card at their existing POS machine — that’s not a convenience fee. That’s MDR pass-through, and it violates their merchant agreement.

How Common Is This in India?

Extremely common. A quick look at r/CreditCardsIndia shows dozens of posts every month about this exact issue. The usual offenders:

Jewellery stores — Especially during wedding season. “Gold pe card? 2% extra, sir.”
Electronics markets — Nehru Place (Delhi), SP Road (Bangalore), Lamington Road (Mumbai)
Small medical clinics and labs — Dentists, pathology labs, even some hospitals
Fuel stations — Some pump attendants still try this, despite fuel being a zero-surcharge category
Government offices — Ironic, but some municipal counters add “processing charges”

What About Online Merchants?

Most large e-commerce platforms (Amazon, Flipkart, Myntra) do not charge surcharges on credit card payments. In fact, they often offer card-specific discounts. But some smaller online sellers, particularly on direct websites, do add a “payment gateway fee” of 1.5–2%. This is more of a grey area, but if they’re framing it as a mandatory surcharge for choosing credit card over UPI, it’s still questionable.

What Can You Actually Do About It?

Here’s your playbook when a merchant tries to charge you extra:

1. Refuse and Cite the Agreement

Tell the merchant: “Your POS terminal agreement with your bank doesn’t allow you to charge me extra. The MDR is your cost.” Most merchants back down when they realize you know the rules.

2. Complain to the Acquiring Bank

Every POS machine is tied to an acquiring bank (HDFC, ICICI, Axis, SBI, etc.). Call the bank’s merchant helpline and report the shop. Banks take these complaints seriously because they risk losing their Visa/Mastercard certification.

3. File a Complaint on the RBI’s CMS Portal

Go to cms.rbi.org.in and file a complaint under “Banking — Credit/Debit Cards.” Include the merchant name, date, amount, and the surcharge charged.

4. Use the Consumer Helpline

Call 1800-11-4000 (National Consumer Helpline) or file online at consumerhelpline.gov.in. This creates a formal record.

Tag the brand, the bank, and @RBI on X (Twitter). Public pressure works faster than formal complaints in India.

The Merchant’s Side: Why They Do It

Let’s be fair. For a small merchant earning thin margins — say a kirana store owner making 5–8% margin on products — absorbing a 2% MDR genuinely hurts. UPI’s zero-MDR policy (for transactions under ₹2,000, and effectively zero for most small merchants) has made card acceptance feel like a penalty by comparison.

This is a real structural issue. But the solution isn’t to illegally surcharge customers — it’s for acquiring banks and card networks to offer more competitive MDR rates for small merchants.

Frequently Asked Questions

Is it legal for a merchant to charge 2% extra for credit card payments in India?

No. The MDR is the merchant’s cost as per their agreement with the acquiring bank and card network. Passing it to customers as a surcharge violates Visa/Mastercard merchant agreements and RBI transparency guidelines.

What is the difference between a surcharge and a convenience fee?

A surcharge is an extra charge for using a specific payment method (like a credit card). A convenience fee is a charge for offering an alternative payment channel. Only convenience fees — disclosed upfront and at a flat rate — are generally permissible.

Can I report a merchant who charges me extra for using a credit card?

Yes. You can complain to the acquiring bank (the bank that provided the POS machine), file a complaint on the RBI’s CMS portal at cms.rbi.org.in, or call the National Consumer Helpline at 1800-11-4000.

Do online merchants also charge credit card surcharges?

Some smaller online merchants add a “payment gateway fee” of 1.5–2% for credit card payments. Large platforms like Amazon and Flipkart do not. If an online seller charges extra specifically for card payments without upfront disclosure, it’s reportable.

Are debit card transactions also subject to surcharges?

Post the 2020 Union Budget, MDR on debit card transactions was effectively removed for merchants with turnover above ₹50 crore. For smaller merchants, MDR on debit cards still exists but is capped at lower rates. Either way, surcharging the customer is not permitted.

What should I do if a petrol pump charges extra for credit card payment?

Fuel stations fall under a regulated category where surcharging is explicitly prohibited. If a petrol pump charges you extra, note the station name and date, and report it to the oil marketing company (IOCL, BPCL, HPCL) as well as the acquiring bank. You can also file an RBI complaint.
