Credit Card Surcharge Rules: Can You Pass Card Fees to Customers?

Card processing fees often run around 3% of every sale. For a service business with thin margins, that can be a large share of profit, so it is natural to ask: can I just charge customers the fee? Sometimes, yes. But US surcharging is governed by card network rules and state laws, and getting it wrong can lead to processor penalties, consumer complaints or legal trouble. This guide explains your options as of 2026 and the safer alternatives.

Warning: This is general information, not legal advice. Card network rules and state laws change. Confirm current requirements with your payment processor and your state attorney general's office before adding any fee.

Three different things people call a "card fee"

They have different rules. Mixing them up is a common mistake.

Surcharge rules: the basics

Card networks allow surcharges on credit cards in most states, with conditions. Common requirements include:

• Credit cards only. Surcharging debit cards and prepaid cards is not allowed, even when the customer chooses "credit" at the terminal.
• A cap. The surcharge generally cannot exceed your actual cost of acceptance, and networks set maximum percentages. Visa's cap has been 3% since 2023. Check each network's current rules.
• Advance notice. Networks and processors have historically required notice before you begin surcharging, often 30 days. Ask your processor what it requires.
• Clear disclosure. Customers must be told before they pay, typically at the store entrance or website entry point and at the point of sale, and the surcharge must appear as a separate line on the receipt.
• Consistency. Surcharges usually must apply the same way across brands of credit cards, or by card brand or product according to network rules.

State law

A small number of states prohibit or restrict surcharges. Connecticut and Massachusetts have long prohibited them, and other states cap the amount, require specific disclosures or require the total price including fees to be shown upfront. "Junk fee" and price transparency laws in some states also affect how you advertise prices. Always check your state's current rules.

Tip: Ask your processor directly whether it supports compliant surcharging. Many processors offer built-in surcharge programs that handle debit detection, caps and receipt lines automatically.

Cash and ACH discounts

Instead of adding a fee for cards, you can offer a lower price for cheaper payment methods. For example: "Price $1,000. Pay by ACH and save 3%: $970."

Why many businesses prefer discounts:

• They are generally permitted more broadly than surcharges
• They feel like a reward rather than a penalty
• They encourage ACH, which is often much cheaper to process

The discount must be real: the posted price is the card price, and the discount comes off for other methods.

Convenience fees

A convenience fee applies when a customer uses a payment channel that is not your normal one. Card network rules typically require it to be a flat amount, disclosed upfront and offered alongside a fee-free alternative. Convenience fees are not a general way to pass card costs to every customer. Check your processor's rules before using one.

A worked example: three approaches for a contractor

A home services contractor bills $4,000 jobs. Card processing costs about 2.9% plus 30¢.

The last approach often works well: the price includes the cost of doing business, and customers who pay by bank transfer are rewarded. It avoids most surcharge rules entirely.

Should you surcharge at all?

Consider:

• Customer expectations. In some industries, surcharges are common; in others, they feel petty and cost repeat business.
• Competitors. If nearby competitors absorb fees, a surcharge may cost you jobs.
• Average ticket. On large B2B invoices, fees matter more, and ACH is a practical alternative.
• Admin effort. Compliance, disclosures and debit detection add complexity.

For many small businesses, the simplest answer is to price fees into rates and encourage ACH for large invoices.

Lowering card costs without any customer fee

Before adding a surcharge, look at the cost itself. Often you can recover more by reducing fees than by passing them on.

• Move large invoices to ACH. Bank transfers and ACH debit are commonly far cheaper than cards for large B2B payments, sometimes a small capped fee rather than a percentage.
• Compare processors. Flat-rate processors are simple, while interchange-plus pricing can be cheaper at higher volume. Ask for a written quote and check monthly fees, PCI fees and chargeback fees.
• Reduce disputes and refunds. Each dispute carries a fee on top of the lost sale.
• Use deposits and progress billing so a single large card payment does not carry the whole job.
• Review your statements quarterly for added fees you did not agree to.

A business processing $40,000 a month by card that moves $15,000 of large invoices to ACH could save several hundred dollars a month without changing a single price or adding a single disclosure.

Disclosure examples

If you do surcharge, keep wording clear and neutral:

"A 3% surcharge applies to credit card payments. This is not greater than our cost of acceptance. No surcharge applies to debit cards, ACH or checks."

For a cash or ACH discount:

"Prices shown are for card payments. Pay by ACH or check and receive a 3% discount."

Checklist before adding any card fee

• ☐ State law checked for surcharge bans, caps and price display rules
• ☐ Processor confirms it supports compliant surcharging
• ☐ Card network notice requirements met
• ☐ Debit and prepaid cards excluded from surcharges
• ☐ Surcharge capped at your cost of acceptance and network limits
• ☐ Disclosures at entry point, point of sale and on receipts
• ☐ Invoices and quotes updated to show fees clearly
• ☐ Staff trained to explain the policy
• ☐ Alternative considered: price increase plus ACH discount

Mistakes to avoid

• Surcharging debit cards
• Adding a percentage higher than your actual cost
• Hiding the fee until the final receipt
• Calling a surcharge a "convenience fee" to avoid the rules
• Ignoring state price transparency laws
