In What States Is It Illegal to Charge a Credit Card Fee?

Navigating the rules around passing processing costs to customers can be tricky, as regulations vary significantly depending on where your business operates. Charging a credit card surcharge is strictly prohibited by state law in Connecticut and Massachusetts, as well as the U.S. territory of Puerto Rico. ^[1] While a handful of other states maintain historical bans on their statute books, federal court rulings have largely rendered those specific restrictions unenforceable or unconstitutional. Furthermore, imposing extra fees on debit card transactions remains strictly illegal nationwide under federal law.

States with Strict Surcharge Bans

If you operate a business in Connecticut, Maine, or Massachusetts, adding an extra fee for credit card use is off-limits. Connecticut enforces a complete prohibition on credit card surcharges, backed by financial penalties for non-compliant businesses. Maine implements an outright ban for standard retail and private transactions, with very narrow exceptions reserved for government bodies handling public fees. Massachusetts maintains a total statutory ban on passing processing costs directly to consumers. Businesses operating within these regions must absorb card processing costs or implement permitted alternatives like cash discounts.

States with Restrictions, Caps, or Evolving Rules

Outside of the strictly prohibited states, the regulatory environment shifts toward caps and disclosure requirements. Colorado restricts credit card surcharges to a maximum limit of 2%.^[2] Other jurisdictions, such as New York, New Jersey, Nevada, and South Dakota, permit surcharges only if they do not exceed the actual processing cost incurred by the merchant. In states like California, surcharges are generally permitted following legal challenges to older state statutes, but consumer protection and hidden fee laws require absolute transparency in how prices and fees are displayed.

Federal Rules and Debit Card Fee Prohibitions

No matter what state your business is located in, federal guidelines draw a hard line regarding debit cards. Charging extra fees or surcharges on debit card transactions is illegal nationwide. This prohibition applies even if a customer runs their debit card through a credit network or inputs a signature instead of a PIN. For credit cards, federal oversight limits standard merchant-applied surcharges while requiring clear upfront disclosures at both the point of entry and the point of sale.

Comparing Payment Processing Fee Methods

When managing transaction costs, businesses generally rely on three different approaches to handle processing overhead legally.

Credit Card Surcharges

1. Allowed in most states, but strictly banned in Connecticut, Maine, Massachusetts, and Puerto Rico.
2. Capped at actual processing costs or a maximum percentage (such as 2% in Colorado or up to 3% elsewhere).
3. Never allowed on debit or prepaid cards under any circumstances.

Cash Discounts & Dual Pricing

1. Permitted nationwide, including in states that ban credit card surcharges.
2. Displays a standard baseline price with a discount given to customers paying via cash or debit.
3. Must be clearly communicated to consumers prior to purchase.

Debit Card Transactions

1. Federal law prohibits extra fees or surcharges on debit purchases everywhere in the U.S.
2. Applies regardless of whether the transaction is processed via PIN or signature.
3. Merchants must absorb standard debit interchange rates without passing them directly as a surcharge line item.

Retail Compliance Adjustments

A retail business operating locations across multiple state lines needed to streamline its point-of-sale fee policies without running afoul of regional consumer protection laws.

The management team initially applied a blanket 3% surcharge across all storefronts, failing to account for regional nuances.

After receiving customer pushback and reviewing state-specific statutes, they realized their Massachusetts and Connecticut branches were in direct violation of strict state bans.

They updated their software to automatically disable credit card surcharges in restricted states while implementing a compliant cash discount model, successfully avoiding potential fines.
