Card Surcharging

Card surcharging is the practice of adding an extra charge to a purchase when the customer pays with a card rather than another method. Merchants use it to recover part or all of the fee they pay to accept cards, known as the merchant discount rate.

Surcharging sits at the centre of a long dispute between merchants and the card networks over who should bear the cost of card acceptance. It is often confused with a cash discount, which lowers the price for non-card payers instead of raising it for card users. Rules differ sharply by country: the practice is capped in the United States, banned for most consumer cards in the European Union and the United Kingdom, and being removed in Australia.

Think of a restaurant that adds a small line to the bill when you pay by card, the same way some hotels add a charge for room service. The restaurant is saying: "Taking your card costs us money, so we are asking you, not every customer, to cover it." Customers who pay in other ways do not see the extra line.

The idea sounds simple, but it raises questions. How big can the extra charge be? Must it be announced at the door? Does it apply to every kind of card? Different countries answer these questions in very different ways, and the card companies have their own rulebooks on top of the law. That is why the same surcharge can be normal in one place and illegal a short drive away.

For decades the major networks barred merchants from charging card users more than other customers, a rule known as the no-surcharge rule. In the United States, a federal ban on credit card surcharges in the Truth in Lending Act was extended in 1981 and allowed to lapse in 1984, but network rules kept the practice rare.

That changed through the long-running US merchant class action over interchange fees. Under a settlement reached with Visa and Mastercard, merchants were allowed to surcharge credit cards from 27 January 2013. In 2017 the US Supreme Court held in Expressions Hair Design v. Schneiderman that New York's no-surcharge law regulated how merchants communicate prices, which brought free-speech arguments into later challenges to state bans. A revised settlement, announced in November 2025 and given preliminary court approval in June 2026, would widen merchants' surcharging options further if finally approved.

Network rules set the outer limits. Visa caps a US credit card surcharge at 3% and Mastercard at 4%, and in both cases the surcharge may not exceed what the merchant actually pays to accept that card. Merchants must give their acquirer 30 days' notice, disclose the surcharge at the store entrance and at the point of sale, and show it as a separate line on the receipt. Surcharges are not permitted on debit cards or prepaid cards, even when the customer signs rather than enters a PIN.

State law can be stricter. Connecticut and Massachusetts prohibit credit card surcharges, while some other states, such as Colorado, cap them below the network limits. A merchant selling across many states, including through e-commerce payments, therefore has to track several sets of rules at once.

In the US, the permitted surcharge rate is the lower of the network cap and the merchant's cost of acceptance, and the customer pays:

• $T$ is the total the card customer pays.
• $P$ is the posted price of the goods or services.
• $s$ is the surcharge rate, written as a decimal.
• $c$ is the merchant's average cost of accepting that card brand, as a decimal.

Suppose a merchant's average cost of accepting Visa credit cards is 2.6% and a customer buys goods priced at $200. The cap is 3%, so the lower figure, 2.6%, applies. The surcharge is $200 \times 0.026 = 5.20$, and the customer pays $205.20. Charging 3% would exceed the merchant's real cost and break the network rules.

The second Payment Services Directive (PSD2) bans surcharges, from 13 January 2018, on consumer debit and credit cards whose interchange is capped by the EU Interchange Fee Regulation, and on euro credit transfers and direct debits. The ban covers the European Economic Area; surcharges on commercial cards and some three-party cards remain possible but must not exceed the merchant's cost. The United Kingdom introduced a similar, broader ban on consumer payment surcharges from the same date.

In Australia, merchants could surcharge up to their cost of acceptance for many years. On 31 March 2026 the Reserve Bank of Australia announced it would remove surcharging on debit, prepaid and credit cards on the eftpos, Mastercard and Visa networks from 1 October 2026, alongside lower interchange caps.

Supporters say surcharging makes the cost of each payment method visible and lets merchants steer customers toward cheaper options. It can also reduce the cross-subsidy in which customers who pay cash help fund rewards for card users. Critics answer that surcharges are often confusing, sometimes exceed the true cost, and fall on customers who have little practical choice. Regulators that ban surcharging usually pair the ban with lower interchange, so that the merchant's effective acceptance cost falls instead of being passed on line by line.
