Why surcharging suddenly matters
Payment processing fees take an average of 2.5% to 3.5% out of every credit card sale. On $500,000 in annual card volume that is $12,500 to $17,500 gone before you pay a single employee.
surcharging is how merchants claw some of that back: add a fee to the sale and the customer who chooses to pay by card covers the cost of it. The idea is simple. The rules are not.
What is perfectly legal in Arizona can cost you a fine in Connecticut. The ceiling changes when you cross a state line, and in one state the whole practice was rebuilt from the ground up in 2024.
This guide walks through all of it. Which states ban it, which cap it, what you have to tell the customer and where you still have to ask permission from a card network.
For reference only, not legal advice. Talk to an attorney before turning on a surcharge program and verify your state’s current rules directly.
States where surcharging is banned
Start with the clean answers. In three states, adding a fee to a credit card sale is simply not allowed:
| State | Status | What you can do instead |
|---|---|---|
| Connecticut | Illegal | Cash discounts with proper disclosure |
| Maine | Illegal | Cash discounts |
| Massachusetts | Illegal | Cash discounts |
Connecticut goes further than the other two. A business cannot advertise one price as a discount and then charge cardholders the higher number at checkout. That is treated as a surcharge wearing a costume. Each occurrence carries a $500 fine.
Cash discounting is the legal sibling in all three states. Post a cash price, add the card cost for anyone who pays another way, and disclose it the way your state requires.
California rebuilt the rules
California rewrote the rules on July 1, 2024. Senate Bill 478, the state’s junk-fee law, works through the Consumer Legal Remedies Act and it is broad enough to catch payment surcharges.
A credit card surcharge listed as its own line item is now illegal in California. What remains permitted:
- Dual pricing: a posted cash price and a posted card price
- all-in pricing: the processing cost built into the price everyone sees
- Restaurant exemptions, which exist but are not clearly drawn
The penalty for getting it wrong runs up to $1,000 per violation. For a shop with a card reader at every register and a checkout page that adds a fee, violations stack fast.
If you sell into California, the practical read is this: stop adding a line at the end and start building the cost into the price you advertise.
Caps, ceilings and legal gray zones
Most states that allow surcharging also narrow it. Two cap it at 2%. Six tie the ceiling to your own costs:
| State | The restriction |
|---|---|
| Colorado | 2% maximum, or your actual cost of processing, whichever is lower. The tightest cap in the country, a ceiling Oklahoma now shares. |
| Oklahoma | Legal for credit cards from November 1, 2025 under SB 677. Only if you also take cash, ACH or check, and only up to the lesser of 2% or your actual cost. Notice is required at the point of entry and the point of sale, on the home page and the checkout page, or verbally by phone. Our Oklahoma breakdown. |
| New York, New Jersey, Nevada, South Dakota, Nebraska, Georgia | Your surcharge cannot exceed your cost of acceptance. You recover what you pay. You do not profit from it. |
| Texas | State law still prohibits surcharging. Federal courts have found those bans unconstitutional, so the working path is convenience fees, service fees and cash discounts. |
| Kansas | Legal with proper point-of-sale disclosure as of January 1, 2025. The 1986 prohibition was struck down in 2021. |
| Minnesota | Mandatory fees have to be inside the advertised price unless the customer can reasonably avoid them. |
| Wyoming | Surcharging is allowed, but cash discounts are capped at 5%. The only state with that limit. |
Georgia adds a second test. A convenience fees is only allowed if you also let people pay by cash, check or money order without charging them anything for the privilege.
Colorado deserves a second look on the math. If your real cost of acceptance is 1.8%, the 2% ceiling does not help you. You are capped at 1.8%.
States running on standard federal rules
The rest of the country runs on the federal baseline:
- Maximum 4%, or your actual processing cost, whichever is lower
- Disclosure at the door and at the register, in person and online
- A separate line on the receipt showing the surcharge
- Card network rules still apply, and they sit on top of state law
| Surcharging legal | Surcharging legal | Surcharging legal |
|---|---|---|
| Alabama | Alaska | Arizona |
| Arkansas | Delaware | Florida |
| Hawaii | Idaho | Illinois |
| Indiana | Iowa | Louisiana |
| Michigan | Mississippi | Missouri |
| Montana | New Hampshire | New Mexico |
| North Carolina | North Dakota | Ohio |
| Oklahoma | Oregon | Pennsylvania |
| Rhode Island | South Carolina | Tennessee |
| Utah | Vermont | Virginia |
| Washington | West Virginia | Wisconsin |
Maryland is not covered in this guide. Confirm its current rules with counsel before surcharging there.
Disclosure you can't skip
Legal in your state is only half the test. Card networks write their own disclosure rules, and a fine is not the only way this goes wrong. Undisclosed surcharges turn into chargebacks, and a chargeback costs you the sale plus a fee whether you win it or not.
At the door
- Clear signage at the entrance, or on the landing page for an online store
- Wording that says a surcharge applies to credit card transactions
At the register
- A verbal disclosure in person before the transaction completes
- Written disclosure on the checkout page online
- The surcharge printed as its own line on the receipt
Before you switch it on
- Visa wants 30 days’ advance notice before a surcharge program goes live
- Mastercard requires registration through your acquirer
- American Express and Discover carry similar notification requirements
Debit is the sharpest line in the source guidance for this guide: debit card surcharging is treated as not permitted, with no exceptions. If your mix leans debit, the whole calculation changes.
Illinois 2026: interchange on tax and tips
Illinois is worth watching because it points at something every merchant pays without noticing. Effective July 2026, it prohibits interchange on the tax and gratuity portions of a transaction, where the acquiring bank is told during authorization or settlement that those amounts are separate.
Run the numbers on a restaurant where tips average 20% and sales tax adds another 10%. That is 30% of every ticket that should never have carried an interchange charge on top.
Watch for other states to follow. The mechanism is not Illinois-specific, and the industry has not finished responding to it.
Our take
Surcharging sounds simple in theory: hand the processing cost to the customer who chose to pay by card. In practice a patchwork of state law turns compliance into a minefield.
We have watched merchants switch it on without knowing their state’s specific rules and end up with fines, or something worse: damaged relationships with customers who saw a 3% add-on nobody mentioned. The math does not work if you lose regulars over a fee they did not expect.
Before you turn on any program, answer three questions:
- Is it legal in my state? This guide is a starting point. Verify with counsel.
- Will my customers accept it? A neighborhood restaurant with loyal regulars absorbs this differently than a gas station where the next pump is a block away.
- Is there a better option? Sometimes fixing what you already pay saves more than a surcharge ever could.
That third one matters more than most merchants realize. A lot of businesses are paying well over the market not because interchange is fixed and high, but because of processor markups, hidden fees and contract terms nobody has read in three years.
What to do next
Surcharging is one tool for handling processing cost. In Connecticut, Maine and Massachusetts it is not even a tool. In California it has been rebuilt into all-in pricing.
The smarter play in any state is knowing exactly what you pay and whether that number is competitive. Most merchants do not. They signed three years ago, have not opened their statements since, and have no idea their effective rate drifted from 2.4% to 3.1%.
VeriFee reads your statements, finds the hidden costs and shows you the real number. No switching, no disruption to how you take payment. Send us a statement and you will know what processing actually costs your business, whether or not you ever add a surcharge.
