Credit card processing fees are rising. For B2B merchants, what was once a comfortable 2.5% effective rate is now closer to 3% — and industry insiders expect that to climb to 3.5–4% within the next two years. It’s no surprise that more businesses are looking at surcharging as a way to offset those costs.
The strategy makes sense on paper: pass the processing fee to the customer and protect your margins. But surcharging comes with a thicket of rules, registration requirements, and state-level restrictions that can expose your business to fines if you’re not careful. Before you flip the switch, here’s what you need to know.
What Surcharging Actually Allows
Surcharging is permitted by all four major card networks: Visa, Mastercard, Discover, and American Express. Note that this applies to credit cards only — surcharging debit cards, including those run as credit, is prohibited under card network rules.
Each network sets its own surcharging limits:
- Visa allows up to 3%
- Mastercard allows up to 4%
- Discover and Amex generally follow Visa’s lead
Because Visa accounts for the majority of credit card transaction volume in the U.S., 3% has become the industry standard cap for surcharging programs. Charging more than your network’s limit — even if another network allows it — puts you out of compliance.
Where It Gets Complicated
State law can override network rules
A handful of states restrict or prohibit surcharging entirely, regardless of what the card brands allow. Colorado, for example, caps surcharges at 2% — meaning Mastercard’s 4% limit is irrelevant there. Maine has additional restrictions. Before implementing a program, you need to verify the rules in every state where you do business.
You cannot profit from surcharging
This is one of the most commonly misunderstood requirements. The surcharge amount cannot exceed your actual cost to process the transaction. If your overall effective processing rate is 2.8%, your maximum surcharge is 2.8% — not 3%. Charging 3% when your cost is 2.8% means you’re pocketing the difference, which is a violation.
As rates continue to rise, this creates a real squeeze. If your effective rate climbs to 3.25%, you’re capped at 3% — meaning you’ll still absorb the remaining 0.25% yourself.
Registration is required, but easier than it used to be
Operating an unregistered surcharge program exposes your business to fines and scrutiny from the card brands. The good news: registration has been simplified considerably. In most cases, registering through Mastercard’s portal — combined with notifying your processor — satisfies the notification requirements for the major card brands. Confirm the process with your processor to make sure all bases are covered.
We just mentioned it, but we can’t stress this enough. You should notify your payment processor that you’re implementing a surcharge program. Your payment processor understands all the regulations and finer nuances of payment setups, and they will make sure things get done right.
How to Register Your Surcharge Program with Mastercard
From there, registering is straightforward. Here’s the process:
- Go to Mastercard’s surcharge registration portal at www.mastercard.us/en-us/business/overview/support/merchant-surcharge-notification.html
- Submit your business information: including your merchant name, location(s), and the surcharge rate you intend to apply
- Receive confirmation: in most cases, this satisfies notification requirements across the major card brands, but confirm with your processor that all networks are covered
- Notify your processor: inform your payment processor that you’ve registered and are implementing a surcharge program
Registration should be completed before your first surcharged transaction.
Alternatives That Don’t Require Registration
If the registration requirements or state restrictions make surcharging impractical for your business, two alternatives accomplish a similar outcome without triggering card brand registration obligations.
Cash Discount Programs
A cash discount program works by setting your listed price to include the cost of card acceptance (for example, a price that reflects a 3.5% processing cost), then offering a discount to customers who pay with cash. No card brand registration is required. However, compliance still matters: you must clearly display the card price and the cash discount. Customers cannot be surprised at checkout.
Dual Pricing
Dual pricing takes the same concept a step further. Both the card price and the cash price are displayed side by side at the point of sale. This is the most transparent approach and is fully compliant with Visa and Mastercard guidelines, provided both prices are visible before the customer completes the transaction.
Neither program requires registration with card brands, but both require clear, consistent price display. In e-commerce environments especially, the card price must be shown prominently. It cannot be revealed only at checkout.

*Applies if implemented incorrectly. Consult your payment processor before implementing any program.
What Happens If You Violate Surcharging Rules
Violating surcharging rules can result in real consequences from card networks and state regulators. Visa and Mastercard can issue fines, suspend your ability to accept their cards, or terminate your merchant account entirely.
State-level violations can also carry additional penalties depending on local law. Beyond formal discipline, chargebacks and customer disputes can increase when surcharging is applied incorrectly, which creates further financial exposure and can damage your relationship with your processor.
Beware of Secret Shoppers
Card networks actively monitor surcharge compliance through secret shopper programs. Representatives visit or transact with merchants to verify:
- Disclosures are displayed correctly
- Surcharge amounts do not exceed the allowed cap
- Debit cards are not being surcharged
Violations identified this way are documented and can trigger formal review. If your program is not set up correctly, you may not know there is a problem until a fine arrives.
The Bottom Line
Surcharging is a legitimate tool for managing rising processing costs, but it comes with real compliance obligations. The break-even rule, state-by-state restrictions, and registration requirements mean it’s not as simple as adding a line item to invoices. Done wrong, it creates liability. Done right, it’s a meaningful margin protection strategy.
If the compliance complexity isn’t worth it for your business, cash discount and dual pricing programs offer a registration-free path to the same goal.
