Surcharging, Decoded

Your One-Stop Guide to Understanding Surcharging

Surcharging can be a powerful tool for managing payment processing costs, but it’s also one that requires clarity, compliance, and careful consideration. Whether you’re a merchant looking to offset credit card fees or a software provider looking to enable surcharging for your users, we will break down everything you need to know about the basics of surcharging.

What Is Surcharging?

Surcharging is the practice of adding a fee to a customer’s transaction when they choose to pay with a credit card. This fee helps merchants recover the cost of credit card processing. The maximum surcharge allowable amount is 3% per transaction.

Important: Surcharging is only allowed on credit card transactions – not cash, debit card or prepaid transactions – and must comply with state laws and card brand rules.

Rules & Regulations Every Merchant Should Know

Surcharging is legal in most U.S. states—but it comes with strict rules that merchants must follow to stay compliant. Here’s a breakdown of the key regulations:

Check your state’s rules: Always verify your state’s current laws before implementing surcharging.
- Prohibited: California (unless the total price, including the surcharge, is displayed to customers), Connecticut, Maine, Massachusetts
- Restricted: Colorado (max 2%), New York, New Jersey, Texas, Minnesota (new rules effective January 2025)
Surcharge Only Credit Cards: You may only apply surcharges to credit card transactions. Debit and prepaid cards are strictly off-limits, even if processed as credit.
Cap the Surcharge: The surcharge must not exceed your cost of acceptance or 3%, whichever is lower.
Notify Card Brands: You must register with card networks (e.g., Visa, Mastercard) at least 30 days before implementing surcharging.
Display Clear Signage: You are required to post signage at the point of entry, point of sale, and on receipts disclosing the surcharge amount – including notification for online purchases.
Itemize the Fee: The surcharge must appear as a separate line item on the customer’s receipt and must be expressed as a percentage.

What Merchants Should Consider:

Compliance Is Key: You must follow the rules and regulations set by the card brands (Visa, Discover, Mastercard).
Technology Support: Your payment technology must be able to support compliant surcharging calculations and reporting. This includes the ability to distinguish between a credit and debit card.
Customer Experience Matters: Transparency and communication are essential to avoid loss of sales, confusion or customer frustration.

What Software Providers Should Consider:

Integration: Ensure your integrated payments platform can calculate, apply, and report surcharges accurately and ensure that your users are also following surcharging regulations.
Compliance Tools: Help merchants stay within legal and card brand guidelines.

Surcharging is the practice of adding a fee to a customer’s bill when they pay with a credit card. This fee helps offset the cost of credit card processing for the merchant and is capped at 3% per transaction. It’s only allowed on credit card payments—not debit or prepaid cards—and must follow specific rules set by card brands and state laws.

Surcharging is legal in most U.S. states, but some prohibit it entirely (e.g., Connecticut, Maine, Massachusetts), while others impose restrictions like fee caps or signage requirements. Before implementing surcharging, it’s important to check your state’s current laws and consult with legal or compliance experts.

To remain compliant:

Register with card brands (e.g., Visa, Mastercard) at least 30 days before starting.
Display clear signage at your entrance, point of sale, and online checkout.
Communicate the surcharge before completing a phone order.
Cap the surcharge at your actual processing cost or 3%, whichever is lower.
Only apply surcharges to credit cards, not debit or prepaid cards.

It depends on your pricing strategy, customer base, and transaction mix. If your prices already account for processing fees, adding a surcharge could result in overcharging. You’ll also want to consider how your customers might react—some may spend less or shift their business to a competitor that does not surcharge.

Surcharging adds a fee to credit card transactions, while cash discounting offers a reduced price to customers who pay with cash. With surcharging, the customer pays more than the advertised price; with cash discounting, they pay less. Both models have different compliance requirements.

You can’t surcharge more than your actual cost of acceptance or the card brand’s maximum—typically 3%. The fee is calculated as a percentage of the transaction amount and must be disclosed to the customer before payment.

You must provide clear disclosure:

At the entrance of your business.
At the point of sale or on the payment terminal.
On receipts and during online checkout.
For phone orders, the surcharge must be disclosed verbally.

No. Surcharges are only allowed on credit card transactions. Applying them to debit or prepaid cards—even if processed as credit—is prohibited by card brand rules.

Potential risks include:

Customer dissatisfaction.
Reduced or loss of sales.
Compliance violations if rules aren’t followed.
Negative brand perception, especially if surcharges aren’t clearly disclosed.

Some businesses report reduced credit card usage or lower overall sales after implementing surcharging.

Start by verifying legality in your state, registering with card brands, and working with your payment processor to enable surcharging. You’ll also need to set up signage and disclosures and train your staff to handle customer questions. Your processor may offer tools to help manage compliance and configuration.
