Visa & Mastercard surcharge rules: staying compliant in 2026

The 40-second answer

A surcharge is a fee you add when a customer pays by credit card. The card networks allow it where state law permits, but they cap it and wrap it in rules. Visa caps a surcharge at 3% (or your actual cost of acceptance, whichever is lower). Mastercard caps it at 4%. You must give 30 days' written notice before you start, never surcharge a debit or prepaid card, and disclose the fee clearly — at the door, at checkout, and as its own line on the receipt. If your state sets a lower limit, the state limit wins.

Visa's surcharge rules

Visa lowered its surcharge ceiling to 3% in 2023, and that's still the number in 2026. You can surcharge up to 3% or your true cost of acceptance for that transaction, whichever is lower — so if your effective rate is 2.6%, you can't round up to 3%. Surcharges apply only to credit cards: Visa debit and prepaid cards are off-limits. You also have to notify your acquirer (your processor) at least 30 days before you begin, register the program, and post clear notice that a surcharge applies. Done wrong, surcharging is one of the faster ways to draw card-network fines, which can be steep.

Mastercard's surcharge rules

Mastercard's ceiling is 4%, but the practical limit is usually lower. Mastercard lets you surcharge two ways. A brand-level surcharge applies the same rate to every Mastercard credit card, capped at the lesser of your average effective rate for Mastercard credit or the 4% ceiling. A product-level surcharge targets a specific Mastercard credit product and can't exceed your cost to accept that product. Like Visa, Mastercard bars surcharges on debit and prepaid cards and requires advance notice — no less than 30 days before you start, to both Mastercard and your acquirer.

The rules both networks share

Strip away the brand differences and the core requirements are the same. Never surcharge debit or prepaid — only credit. Never charge more than your cost of acceptance, and never exceed the brand cap. Give 30 days' notice before you start. Disclose the surcharge at the point of entry, at the point of sale, and as a separate line item on the receipt — it can't be baked silently into the price. And surcharge consistently across the brands you accept; you can't single one network out unfairly. These rules exist so the customer always sees the fee before they pay.

State law can override the networks

The card brands set a ceiling, but your state can set a lower one — or ban surcharging entirely. A handful of states prohibit credit-card surcharges, and at least one caps them below the brand limit, so the strictest applicable rule is the one you have to follow. This is exactly where merchants get tripped up: a setup that's fine in one state can be a violation in another.

The simpler alternative: dual pricing

Here's the move most of my clients prefer. Instead of adding a fee on credit, you post two prices — a card price and a lower cash price — and let the customer choose. Because the cash price reads as a discount rather than a surcharge, a properly built cash-discount or dual-pricing program is legal in all 50 states, with far fewer of the registration and signage traps. You still need both prices shown clearly before checkout and correct programming on your terminal, but you skip the state-by-state surcharge map. See how cash discount vs. dual pricing vs. surcharging compares, and how zero-cost processing takes your fees toward zero.
