Important, before anything else
This is a general explanation, not legal advice. Surcharging rules are set by a combination of card network operating regulations and state law, both of which change, and several states have seen active litigation over their statutes. Verify the current position for the states you operate in with your processor and, where the amounts are material, with a lawyer. Do not implement surcharging based on a blog post, including this one.
What surcharging is
A surcharge is a fee added to a transaction specifically because the customer is paying by credit card. The customer sees a line item that increases the total.
It is distinct from a cash discount program, where the posted price includes the card cost and customers paying cash receive a reduction. The two are often discussed together and are treated differently under both card brand rules and state law. CoreCommerce supports compliant surcharging.
The card brand rules
These apply regardless of where you operate, and they are more restrictive than most merchants expect.
Credit only, never debit
Debit cards cannot be surcharged, full stop, regardless of whether the customer runs it as debit or credit. This is the single most common compliance failure.
A capped percentage
Card networks cap the surcharge, and it cannot exceed your actual cost of acceptance for that card. You cannot profit from a surcharge.
Advance notice to the networks and your processor
Surcharging generally requires notifying the card networks and your acquirer before you begin. Starting without notice is a violation even where state law permits the practice.
Clear disclosure at entry and at the point of sale
Signage where customers first see prices and again at checkout, plus a separate line item on the receipt showing the surcharge amount.
Consistency across brands
You generally cannot surcharge one card brand and not another in a way that disadvantages a specific network.
Why state law varies
Beyond the card brand rules, individual states regulate surcharging separately. Some prohibit it outright, some cap it below the network cap, some impose specific disclosure language, and several have had their statutes challenged in court with mixed outcomes.
The practical consequence is that a national business cannot apply one policy everywhere without checking each state, and a policy that was compliant two years ago may not be now. This is genuinely a moving target, which is why the verification step matters more here than in most areas of payments.
Whether it is right for your business
Worth thinking about commercially, not just legally.
It works best on large tickets
On a $4,000 invoice the surcharge is meaningful money. On a $12 sale it is a rounding error that annoys the customer for no material gain.
It works best in B2B and trades
Business customers generally understand card costs. Retail and hospitality customers frequently react badly, and the reputational cost can exceed the saving.
Your competitors matter
If nobody in your category surcharges, being the only one is a competitive disadvantage regardless of how well you disclose it.
Debit is the escape valve
Since debit cannot be surcharged, a surcharge program tends to push customers toward debit, which is cheaper for you anyway. That shift is often worth more than the surcharge revenue itself.
If you decide to do it
Confirm state position for every state you operate in, notify the networks and your processor in advance, configure your terminals and gateway so debit is automatically excluded, post compliant signage at the entrance and at the point of sale, show the surcharge as a separate line on every receipt, and cap it correctly against your actual cost of acceptance.
Getting any one of those wrong exposes you to network fines and, in some states, statutory penalties. Have your processor configure it rather than doing it yourself.
Common questions
Is it legal to charge customers a fee for paying by credit card?+
In most of the country, yes, but it is tightly governed. Card network rules apply everywhere and are stricter than most expect, and individual states add their own rules, some prohibiting it. Confirm the position for your states first. This is not legal advice.
What is the difference between surcharging and a cash discount?+
A surcharge adds a fee when a customer pays by credit card, shown as a line item that raises the total. A cash discount builds the card cost into your posted price and reduces it for cash payers. The two are regulated differently.
What are the card brand rules for surcharging?+
Credit cards only, never debit, even when run as credit. The surcharge is capped at the lower of your cost of acceptance or the networks' fixed percentage cap, so you cannot profit. Notify the networks and your processor in advance, and disclose it clearly. Not legal advice.
Why can't I surcharge debit cards?+
Card network rules prohibit surcharging debit outright, regardless of how the customer runs it. It is the most common compliance failure. In practice a surcharge program nudges customers toward debit, which costs you less anyway, so that shift is often worth more.
Should my business surcharge at all?+
It works best on large tickets and in B2B or the trades, where customers understand card costs. In retail and hospitality, customers often react badly and the reputational cost can exceed the saving. Your competitors matter too: being the only one who surcharges is a disadvantage.
