Last verified: October 2026. Surcharge law moves with legislation and court decisions — check the date on this page, and confirm with your state attorney general or processor before enabling surcharging.
The short answer: surcharging is legal in most of the U.S., but three states ban it outright (Connecticut, Maine, Massachusetts — plus Puerto Rico), several cap it below the card-network maximums, and a few impose strict disclosure rules with real penalties. Cash discounts and dual pricing remain legal everywhere, including the ban states.
Before building a surcharge program, model what it actually recovers — the Payment Processing Cost Analyzer shows your true cost, which is the legal ceiling for any surcharge.
States that ban surcharging outright
| State | Rule |
|---|---|
| Connecticut | Surcharges prohibited. Cash discounts allowed. |
| Maine | Surcharges prohibited. Cash discounts allowed; the non-discounted price must be clearly shown upfront. |
| Massachusetts | Surcharges prohibited. Cash discounts allowed. |
| Puerto Rico | Surcharges prohibited. |
In these states, a compliant cash discount or dual pricing program is the legal path to the same economics. Cash Discount vs. Surcharge vs. Dual Pricing
States with caps or special rules
| State | Rule |
|---|---|
| Colorado | Surcharges allowed but capped at 2% of the transaction (or actual cost, if lower) — below Visa’s 3% network cap. |
| Illinois | Surcharges capped at 1% or actual processing cost, whichever is lower. (Illinois has also moved to restrict interchange on the tax and gratuity portions of transactions — confirm current status before relying on it.) |
| New York | Surcharging allowed, but the total credit-card price must be displayed in dollars and cents before checkout. Listing a lower price and adding the surcharge at the register violates the law — penalties run $500 per occurrence. |
| California | The old ban was struck down in federal court on First Amendment grounds; surcharging with proper disclosure is generally permitted as of 2026. This is the most litigated state in this area — verify current guidance. |
| Texas, Florida, Kansas | Bans remain on the books but have been struck down or rendered unenforceable by federal court rulings. Treat as legally uncertain: compliant disclosure is the safe posture. |
| Minnesota | Requires mandatory fees — including surcharges — to be included in the advertised price unless the fee is reasonably avoidable by the consumer. Structure your disclosure accordingly. |
All other states
In the remaining states, surcharging is generally permitted subject to the card-network rules, which apply nationwide regardless of state law:
- Visa cap: 3% (lowered from 4% in April 2023). Mastercard cap: 4%. Practical ceiling for merchants accepting both: 3%.
- Never exceed your actual cost of acceptance. If your effective rate is 2.4%, your surcharge tops out at 2.4%.
- Never surcharge debit or prepaid cards — even when run as “credit.” Federal law and network rules both prohibit it.
- 30-day advance notice to Visa/Mastercard (through your processor) before your first surcharge.
- Clear disclosure: signage at the entrance and point of sale; the surcharge itemized as its own line on every receipt. Online, disclose on the checkout page before the transaction.
Violating network rules risks fines from $50,000 into the millions and loss of surcharging privileges — the state being permissive doesn’t make the network rules optional.
How to use this page
- Find your state above. Ban → use cash discount/dual pricing. Cap → set your program at or below it. Special disclosure → build the disclosure into your signage and checkout before launch.
- Confirm it’s current. Laws change every legislative session. Your processor publishes state rules (their compliance depends on them) — ask for the current sheet.
- Do the network compliance too. State permission + network violation still equals fines. The 30-day notice, the debit exclusion, and the actual-cost cap are non-negotiable everywhere.
- Model the economics. A surcharge capped at 2% (Colorado) or 1% (Illinois) recovers far less than the 3% headline — run your volume through the analyzer to see what your state’s cap actually recovers.
Your surcharge can never legally exceed your true processing cost — the analyzer computes that number from your statement or quote, so your program stays inside the lines.
Methodology
State rules compiled October 2026 from multiple merchant-compliance surveys published in 2026, cross-checked across sources. Where sources conflicted or a state’s status rested on litigation rather than statute (Texas, Florida, Kansas, California), the page says so instead of picking a winner. Network rules (caps, debit exclusion, 30-day notice) are Visa/Mastercard program rules. This page is a reference, not legal advice — for high-volume or multi-state operations, confirm with counsel.
Frequently asked questions
How often does this change?
Often enough to matter: the last decade saw bans struck down in New York, Texas, California, Florida, and Kansas, new caps added in Colorado and Illinois, and disclosure laws tightened in New York and Minnesota. Treat any surcharge-law page without a verification date — including this one, if it’s old — as suspect.
I’m in a ban state. What are my options?
Cash discount or dual pricing programs, which are legal in all 50 states. They achieve similar economics without triggering surcharge bans or the debit-card prohibition.
Do these rules apply to online businesses?
Yes. Your business location’s state law generally governs, and network rules apply regardless of channel. Online, the disclosure must appear on the checkout page before the transaction is processed.
What about American Express and Discover?
Both permit surcharging within their own program rules (Amex historically capped at similar levels; Discover follows the same disclosure framework). If you accept all four networks, the strictest applicable cap governs your program in practice.
My processor set up my surcharge program. Am I covered?
Mostly — processors handle the network notice and terminal configuration. But state-law compliance (caps, disclosure wording) remains your responsibility, and not every processor’s default setup respects every state’s quirks. Verify, don’t assume.
