Surcharge fees let businesses pass credit card processing costs to customers who pay by credit card. These fees can help protect your margin, but the compliance requirements, customer response, and competitive risks can outweigh the savings. Whether your business should implement surcharge fees depends on your margins and market. One survey found 35% of small businesses in the US include surcharge fees.

Below, we’ll discuss how surcharge fees work, where they’re legal, what the risks are, and how to correctly set up surcharges if you decide to implement them.

Highlights

• Jurisdiction is important. Credit card surcharges are legal in most US states and Canada but banned in the EU.

• A surcharge can’t exceed your cost of card acceptance or your card network’s set percentage, and it must exclude debit cards.

• Businesses with thin margins and high average transaction values tend to benefit most from surcharge fees.

What is a surcharge fee?

A surcharge fee is an additional charge a business adds to a transaction when a customer pays by credit card. The fee passes the cost of credit card processing to the customer who chooses that payment method.

When a customer pays with a credit card, the business is typically charged several fees, including an interchange fee. The fees often add up to between 1.5% and 3.5% of the transaction, depending on card type, market, and how the card is presented. Premium rewards cards and corporate cards tend to cost more, while basic customer credit cards cost less.

How does a surcharge fee work?

A surcharge fee passes on some or all of the credit card processing cost to the customer as a line item at checkout. Here’s how it works:

• Percentage cap: Card network rules usually dictate that the surcharge can’t exceed the business’s merchant discount rate (MDR) or a fixed percentage (e.g., Visa sets a 3% cap in the US), whichever is lower.

• Pre-transaction disclosure: The surcharge is shown to the customer before the transaction completes—at the point of sale and on the receipt.

• Credit cards only: The surcharge applies only to credit cards. Debit cards, including prepaid cards, are excluded.

• Network registration: Visa requires official notice before a business starts surcharging. Mastercard no longer requires this. Stripe can handle the registration process and apply surcharges through its platform.

Are surcharge fees legal?

Credit card surcharges are legal in many US states. Sellers have been allowed to add surcharge fees in the US and US territories since 2013. But 10 US states (California, Colorado, Connecticut, Florida, Kansas, Maine, Massachusetts, New York, Oklahoma, and Texas) have surcharging restrictions in the form of fee caps or bans. The relevant laws can change, so check them before you implement surcharge fees.

Even where surcharging is legal, you must disclose the surcharge dollar amount on every receipt, and disclosures must be posted at the point of entry and point of sale. In online stores, the surcharge policy must be disclosed on the first page that references credit card brands.

Outside the US, the rules can vary:

• EU: The revised Payment Services Directive (PSD2) banned surcharging on card payments.

• Canada: As of 2022, Visa and Mastercard allow surcharging in the country.

• Australia: Surcharging will no longer be permitted starting October 1, 2026.

Should businesses introduce a surcharge fee?

Whether your business should use a surcharge fee depends on your margins, your customer base, and what your competitors are doing. A surcharge can be a financially rational decision or a customer relations problem (and sometimes both at once).

Here’s how surcharge fees can help:

• Credit card fees accumulate. A business that processes $1 million annually with an average interchange rate of 2.5% pays $25,000 to card networks and issuing banks. Industries with thin margins feel this acutely.

• Surcharge fees can make pricing more transparent. Customers who pay cash stop subsidizing customers who pay with premium rewards cards.

Here’s how surcharge fees can backfire:

• Unexpected fees at checkout can increase cart abandonment online and create negative brand associations in physical locations. If a customer is surprised by a surcharge, it can change their decision to buy from you.

• If your closest competitor accepts credit cards without a surcharge, customers might wonder why they have to pay you more.

Customer demographics and average transaction size matter when you’re deciding whether to implement a surcharge fee. If your customers skew toward cash or check payments, a surcharge might have less impact. But if they’re expecting a friction-free digital checkout, it will likely create more resistance. The bigger the transaction size is, the more likely customers are to notice an additional fee: a 2.5% surcharge on a $15 purchase is about 38¢, but the same surcharge on a $4,000 service is $100.

What are the risks of adding a surcharge fee?

The biggest risk of adding a surcharge fee is incorrect implementation. Card network rules on surcharging are specific, and violations can result in fines for your acquirer.

Avoid these surcharge fee mistakes:

• Skipping network registration: Visa requires notice before you start surcharging. Don’t start surcharging without registering.

• Surcharging debit cards: This isn’t permitted, even when it’s a prepaid card.

• Exceeding the cap: Your surcharge can’t exceed your MDR or the network cap, whichever is lower.

• Failing to disclose: The surcharge must be visible before the transaction and clearly posted in the store or on your website.

Beyond compliance, there’s reputational risk. Retail customers who encounter an unexpected surcharge are more likely to complain publicly than to switch payment methods. B2B customers, who often pay by Automated Clearing House (ACH) payment or check, tend to be more pragmatic.

How should businesses implement a surcharge fee?

Implementing a surcharge fee follows a specific sequence in the US, and skipping steps can create compliance exposure. Before you start, confirm that surcharge fees are permitted where you operate.

Once you do so, here’s how you implement a surcharge fee in the US:

• Register with card networks: Visa requires you to notify it and your acquirer of your intent to surcharge at least 30 days before surcharging begins.

• Set your surcharge percentage: Your surcharge can’t exceed your cost of acceptance or the percentage set by the card network, whichever is lower. If you don’t know your effective interchange rate, your payment provider can tell you.

• Update your disclosures: Add signage at physical locations, disclosure on your website for online sales, and a surcharge line item on every receipt.

• Configure your checkout: The system must be able to distinguish credit from debit at the point of card entry and apply the surcharge automatically when applicable.

• Train customer-facing staff: Anyone who handles payments needs to know how to explain the fee plainly (e.g., “We charge a fee for credit card payments to cover our processing costs. You can avoid it by paying with cash or debit.”).

How high should a surcharge fee be?

The surcharge fee ceiling for Visa is 3% or your MDR, whichever is lower. The cap for Mastercard is 4%.

Setting the surcharge at exactly your processing cost is permitted and easier to explain to customers. If you’re using surcharges to increase revenue beyond the cost of interchange, you’re noncompliant and likely to hear about it from your payment provider or auditor.

Some businesses might want to apply a flat fee instead of a percentage (e.g., $2 per credit card transaction). But the calculation requires care: on small transactions, a flat fee might exceed Visa’s 3% cap, which makes it noncompliant. A percentage-based surcharge avoids that problem.
