Charging Customers a Card Fee (Surcharging Rules)

TL;DR

Most US states let you surcharge credit cards. Connecticut, Maine, Massachusetts and Puerto Rico ban it outright. California's pricing law killed it there too
Your cap is the lower of two numbers. The network limit, or your own merchant discount rate. Visa caps at 3%, Mastercard at 4%. Take both and 3% is your real ceiling
Never surcharge debit or prepaid. Not even when the cardholder picks "credit" at the terminal. It's the violation processors see most
Notify the networks and your acquirer 30 days before you start. Then disclose at the door and at checkout. The receipt needs its own line too
A "free processing" pitch at 3.5-4% is a Visa violation
If your state bans it, use a cash discount instead. Same economics, none of the network paperwork

You want to stop eating 3% on card sales. You've been told you can just pass it to the customer. Sometimes you can. Three things decide it. Your state's law, the network caps, the disclosure rules. Not hard, just specific. Get one wrong and it's a fine instead. This page is the compliance side. For whether it's worth doing at all, see Surcharging in Payments.

What is Surcharging?

A surcharge is a fee added for paying by credit card. It covers what the card costs you to accept.

Network rules banned it outright until 2013. A class action settlement opened it up. That was In re Payment Card Interchange Fee and Merchant Discount Antitrust Litigation. State law still decides where you can do it.

Term	Definition	Key Difference
Surcharge	Fee added for credit card payment	Added to base price
Convenience Fee	Flat fee for alternate payment channel	For non-standard channels only
Cash Discount	Lower price for paying with cash	Base price is credit price
Service Fee	General fee not specific to payment	Not payment-method specific

The distinctions matter. Each one carries its own rules. Calling a surcharge a "convenience fee" doesn't change which rules apply.

Network Surcharging Rules

Visa Requirements

Cap: 3% of transaction OR your merchant discount rate, whichever is lower

Advance Notice:

Notify Visa and your acquirer 30 days before implementing
Register at www.visa.com/merchantsurcharging

Card Type Restrictions:

Credit cards only
Never surcharge debit or prepaid cards (even if cardholder selects "credit" at point of sale)

Disclosure Requirements:

Clear disclosure at store entrance or website homepage
Clear disclosure at point of sale before payment processed
Separate line item on receipt (not buried in subtotal)

Equal Treatment:

Must surcharge Visa on same terms as equal-or-higher-cost competitors
Brand-level or product-level surcharging permitted

Non-Compliance Penalties:

Visa enforcement actions can result in significant fines
Penalties run from tens of thousands to over a million dollars

Mastercard Requirements

Cap: 4%, or your merchant discount rate, whichever is lower. A 2024 settlement would have changed the surcharging terms. The court rejected it in June 2024. A later settlement reached in 2025 has preliminary approval only. It isn't in force either. Nothing's changed yet. Don't plan around either one. Verified 1 August 2026.

Advance Notice:

Written notice to Mastercard and acquirer 30 days before start
Acquirer forwards notification to Mastercard

Card Type Restrictions:

Credit cards only
Never surcharge debit or prepaid cards

Disclosure Requirements:

Clear disclosure required at all customer touchpoints

Common Violations

Visa caps you at 3%. So a "free processing" program pitching 3.5-4% is pitching a violation. Most of them miss the disclosure requirements too. The fines land on you. Not on the reseller who sold it.

State-by-State Surcharging Status

States Where Surcharging Is Banned Outright

State	Status	Notes
Connecticut	Prohibited	No surcharges allowed
Maine	Prohibited	No surcharges allowed (9-A M.R.S. 8-509)
Massachusetts	Prohibited	No surcharges allowed
Puerto Rico	Prohibited	Territory prohibition

This list isn't complete, and it moves

Other states impose limits or sit in flux. Oklahoma is one. State surcharging law changes often. The table above was last checked against published state law in 2025. Check with local counsel before you switch a surcharge on.

States with Specific Restrictions

State	Restriction	Details
Colorado	2% cap	Lower than network caps
New York	Complex	Must display total credit card price; restricts how surcharges shown
New Jersey	Cost limit	Cannot exceed actual processing cost
Nevada	Cost limit	Cannot exceed actual processing cost
South Dakota	Cost limit	Cannot exceed actual processing cost
Minnesota	Disclosure rules	Mandatory fees must be in advertised price (Jan 2025)
California	Effectively prohibited	SB 478 (July 2024) bans displaying prices below total cost; surcharging is no longer viable for most merchants
Texas	Complex/Evolving	State law prohibits but federal courts ruled unconstitutional; AG says enforceable

New York: display the full credit card price up front. Most New York merchants switch to cash-discount presentation instead. It's the cleanest way to comply.

California: SB 478 took effect 1 July 2024. It bans showing a price below the full cost, mandatory fees included. A surcharge is technically avoidable rather than mandatory. That distinction hasn't made surcharging workable here. Treat California as a no-surcharge state.

Texas: unresolved. Federal courts ruled the prohibition unconstitutional. The state AG says it's still enforceable. Don't be the test case. Talk to local counsel first.

States Where Surcharging is Generally Permitted

The remaining ~40 states allow it. Network rules and the disclosure requirements still apply. Verify your own state before you switch anything on. These laws move.

Implementation Requirements

Before Surcharging

Confirm state law allows surcharging in all locations where you operate
Determine your merchant discount rate (MDR) for applicable cards
Set surcharge at the lower of MDR or network cap (3% for Visa)
Notify Visa: www.visa.com/merchantsurcharging
Notify Mastercard: Written notice to acquirer who forwards to Mastercard
Wait 30 days before implementing

Disclosure Requirements

Touchpoint	Requirement
Entry point	Sign at store entrance or website homepage
Point of sale	Clear notice before payment is processed
Receipt	Surcharge as separate line item
Online	Visible before checkout completes

Signage Examples

Visa publishes sample compliant signage at https://usa.visa.com/support/small-business/regulations-fees.html.

Sample In-Store Sign:

"We impose a surcharge on credit card transactions that is not greater than our cost of acceptance. We do not surcharge debit cards."

Sample Online Disclosure:

"A [X]% surcharge will be added to credit card transactions. This fee covers our cost of accepting credit cards. We never surcharge debit cards."

Surcharging vs. Cash Discount Programs

Feature	Surcharging	Cash Discount
Listed price	Base price (lower)	Credit card price (higher)
Adjustment	Fee added for credit	Discount for cash
Perception	Penalty for using card	Reward for using cash
Disclosure	Network-mandated requirements	State consumer protection laws
Debit cards	Cannot surcharge	Discount applies to cash only
Network notification	Required 30 days in advance	Not required

New York Implications (Feb 2024)

New York wants the full credit card price up front. Not a lower pre-surcharge subtotal. That breaks the usual model.

Common Approaches in NY:

Use a cash-discount approach (list higher price, discount for cash)
Show only the final card price (no line-item surcharge)

Convenience Fees

Convenience fees are not surcharges. Different rules apply.

Requirements

Must cover a genuine alternate payment channel
Flat fee, never a percentage
The channel has to differ from how you normally get paid
You can't charge one if cards are your only channel
You can't charge one if you're 100% card-absent

Eligible Merchants

Convenience fees usually fit:

Government agencies (paying taxes online when mail is standard)
Educational institutions (tuition payments)
Utility companies (bill payments)
Other merchants with primary non-card payment channel

Example

A utility normally takes payment by mail or in person. It can charge a convenience fee for phone or online. They're genuine alternate channels.

A card-first retailer can't. There's no alternate channel to be convenient about.

Issuer Perspective

Issuers see surcharging in the cardholder base:

What you'll see:

Cardholders steering away from the cards that get surcharged hardest
More "hidden fee" complaints
Some cardholders switching to debit, which can't be surcharged

What you can do:

Issuers can't stop a compliant surcharge. They can:

Educate cardholders about surcharge limits and rights
Provide information about disputing non-compliant surcharges
Monitor for reports of excessive or deceptive surcharging
Report non-compliant merchants to networks

Compliance Monitoring

For Acquirers

Ensure merchants have properly notified networks before surcharging
Monitor for excessive surcharge percentages (above caps)
Respond to cardholder complaints about surcharging
Visa runs mystery shopping audits, so assume the signage gets checked

For Merchants

Documentation to Maintain:

Your merchant discount rate (to prove the surcharge doesn't exceed it)
Network notification confirmations
Staff training records on disclosure requirements
Photos of compliant signage

Ongoing Compliance:

Train staff on proper disclosure
Audit receipts for correct line-item display
Monitor customer complaints
Update signage if rates change

Common Compliance Failures

Failure	Why It's a Problem
Surcharging debit cards	Never permitted, even if "credit" selected
Exceeding network caps	3% Visa max often violated
No advance notice	Must notify networks 30 days prior
Missing disclosures	Required at entry, POS, and receipt
Surcharging in prohibited states	CT, ME, MA, PR outright bans
Burying surcharge in total	Must be separate line item

Before you switch this on

Wondering whether surcharging is worth it at all? See Surcharging in Payments. It has the business case, the ROI math, and the implementation approach.

Just trying to cut processing costs? Check whether you're overpaying first. On flat-rate pricing (2.9% + $0.30), moving to interchange-plus often saves more. And it costs your customers nothing. Start with Understanding Your Costs and Buying Payments.

Next Steps

Evaluating surcharging?

Check state-by-state status - Prohibited in CT, ME, MA, PR
Understand network rules - Visa 3%, Mastercard 4%
Compare to cash discount - Different rules

Implementing surcharging?

Follow implementation requirements - Notify, wait, disclose
Set up disclosures - Entry, POS, receipt
Avoid common failures - Debit, caps, states

For acquirers and issuers?

Monitor compliance - Acquirer responsibilities
Understand issuer impact - Cardholder effects
Track violation patterns - What to watch for
