What Is Surcharging?
A credit card surcharge is an additional fee merchants add to a transaction when a customer pays with a credit card—as opposed to cash or debit. The fee is intended to recover a portion of the interchange fee the merchant pays on every card transaction.
Credit card networks (Visa, Mastercard, American Express) have their own rules about surcharging. These rules have shifted over time, and 2025–2026 has seen a notable comeback in merchant surcharging programs as card fees continue to rise.
Why Surcharging Is Making a Comeback
For years, many merchants avoided surcharging due to customer perception concerns and complexity. But three things have changed:
- Interchange fees keep climbing: The all-in cost of accepting credit cards has risen significantly, especially for premium rewards cards
- Surcharge rules clarified: Network rules are now well-established, and merchant acquirers have streamlined the compliance process
- Consumer shift to credit: Cash usage continues to decline, meaning fewer customers benefit from the “discount” that motivated cash discounting programs
As a result, restaurants, retailers, and service businesses are increasingly adopting or re-adopting surcharge programs.
State-by-State Rules: What ISOs Need to Know
Surcharging is legal in most states, but with important conditions. Here is a state-by-state overview for 2026:
States Where Surcharging Is Fully Legal (with network compliance)
- California: Surcharging legal; capped at 3% or the merchant’s actual interchange cost, whichever is lower; must be disclosed before payment
- Texas: Surcharging legal; no state-specific cap; must be clearly disclosed
- Florida: Surcharging legal; same disclosure requirements as federal rules
- New York: Surcharging legal; same cap as California (3%); disclosure required at point of entry
- Illinois: Surcharging legal; must be clearly posted at the business entrance and register
- All 47 other states: Surcharging generally legal under federal network rules; check with your acquirer for state-specific disclosure requirements
States Where Surcharging Is Restricted or Prohibited
- Connecticut: Surcharging effectively prohibited; merchants may offer a discount for cash but cannot add a fee for credit
- Massachusetts: Surcharging prohibited; only cash discounts are permitted
- Oklahoma: Surcharging prohibited; only cash discounts permitted
- Kansas: Surcharging prohibited; cash discount only
- New York (for credit cards specifically): Surcharging technically legal but heavily restricted; many merchants use dual pricing instead
Note: Rules change. Always verify current regulations with your payment processor and legal counsel before implementing a surcharge program.
Surcharging vs. Cash Discounting vs. Dual Pricing
These three models are often confused, but they work differently and have different legal profiles:
| Model | How It Works | Best For |
|---|---|---|
| Surcharge | Adds fee when credit card is used | States where legal; businesses with high credit card mix |
| Cash Discount | Offers discount for cash; credit card is regular price | States where surcharging is restricted (CT, MA, OK, KS) |
| Dual Pricing | Lists two prices—one for cash, one for card | Most states; simplest customer communication |
What Merchants Need to Do to Comply
A compliant surcharge program requires:
- Network registration: Both Visa and Mastercard require merchants to register their surcharge program and pay an annual fee
- Clear disclosure: Posted at the entrance and at the point of sale before the customer enters their card information
- Consistent application: The surcharge must apply to all credit card transactions of the same type (e.g., all Visa consumer credit cards)
- No surcharge on debit cards: Visa and Mastercard rules prohibit surcharging on debit transactions
- Maximum cap: The surcharge cannot exceed the merchant’s actual cost of accepting that card type, or 3% (whichever is lower for Visa/MC)
The Risk: Chargebacks and Customer Complaints
Surcharging generates customer friction. Some customers will pay and leave; others will dispute the charge, especially if they weren’t clearly informed beforehand. Merchants should expect a modest increase in chargebacks in the first few months after implementing a surcharge program—until customer expectations adjust.
The fix is disclosure: clear signage at the entrance, a notice on the menu or invoice, and a terminal prompt that confirms the customer saw the fee before they approve it.
What ISOs Should Do
If your merchant portfolio includes businesses in states where surcharging is legal, this is a value-add conversation worth having. Many merchants don’t know they can surcharge, don’t know how to implement it compliantly, or think it’s more complex than it is.
Your role:
- Know the rules for each state where your merchants operate
- Help merchants understand the revenue opportunity and compliance requirements
- Coordinate with your acquirer to ensure proper network registration and processing configuration
- Provide compliant signage—many processors offer ready-made templates
The Bottom Line
Surcharging is a legitimate, legal tool for offsetting card processing costs—and adoption is growing. The states where it’s restricted are narrowing. Merchants who implement it correctly can recover 1–3% per transaction; those who do it incorrectly face fines and chargebacks. If you’re an ISO with merchants in states where surcharging is legal, this is a conversation worth having in your next merchant review.
