Credit Card Surcharge Law & Calculator (2026)

Under nationwide Visa Core Rules and Mastercard Operating Regulations enacted in April 2023, the maximum allowable credit card surcharge is capped at 3.00% (reduced from the previous 4.0% cap), or the merchant's actual verified cost of card acceptance—whichever is lower. Federal law does not impose a federal percentage cap, but individual state statutes and card brand operating agreements strictly enforce this 3.0% ceiling.

No. Under the federal Durbin Amendment (Section 1075 of the Dodd-Frank Act, codified at 15 U.S.C. § 1693o-2), it is strictly illegal to surcharge debit cards or prepaid debit cards. This applies uniformly across all 50 states, even when a customer runs a debit card as 'Credit' (signature debit) without entering a PIN. Point-of-sale terminals must perform automated BIN lookups to suppress surcharges on debit cards.

As of 2026, Massachusetts (Mass. Gen. Laws ch. 140D § 28A) and Connecticut (Conn. Gen. Stat. § 42-133ff) maintain strict statutory prohibitions against credit card surcharges. In California, Florida, Texas, and several other states, earlier statutory bans were invalidated by federal courts on First Amendment commercial speech grounds. Colorado permits surcharges but caps them at the lower of 2.0% or actual cost. New Jersey and Minnesota cap surcharges strictly at the merchant's actual processing cost.

Effective February 11, 2024, New York General Business Law § 518 was amended by Senate Bill S1048A to require merchants who surcharge to display the total credit card price (in dollars and cents) anywhere prices are shown. A business can no longer simply post a sign stating '3% fee added at the register.' The price tag, menu, or website must explicitly show the higher card price, or display both the cash price and card price side-by-side.

A credit card surcharge adds an extra fee (up to 3%) onto the listed sticker price for cardholders. A cash discount program sets the listed price as the card price and gives a discount to customers paying with cash or check. A convenience fee is a flat or percentage fee charged only on non-standard payment channels (such as online portal or phone orders) where in-person payment is the standard channel, governed by distinct card brand rules.

Yes. Both Visa and Mastercard require merchants to provide at least 30 calendar days advance written notice to their acquiring bank before implementing a credit card surcharging program. Merchants must also certify that their terminals suppress debit surcharges and provide itemized receipt disclosures.

Card network regulations and state consumer protection statutes require merchants to post conspicuous signage at the point of store entry and at every point of checkout or POS counter. Signage must clearly state the surcharge percentage (up to 3.0%), inform customers that the fee does not exceed the merchant's cost of acceptance, and specify that debit cards are exempt.

The surcharge must be displayed as a distinct, itemized line item with its exact dollar amount on the customer's transaction receipt. It cannot be combined with sales tax or hidden in general delivery or service fees. The receipt must clearly delineate: (1) Base Transaction Amount, (2) Credit Card Surcharge Dollar Amount, (3) Applicable Sales Tax, and (4) Total Charged.

In the vast majority of US states, credit card processing surcharges passed along to the customer are considered part of the gross taxable sales price for tangible personal property. As a result, sales tax must be computed on the post-surcharge total. Merchants should consult their state Department of Revenue or certified CPA for tax matrix configuration.

To net an exact target amount T when paying rate r and fixed fee f, the gross invoice must equal: Gross = (T + f) / (1 - r). Merely adding r to T creates a shortfall because the processor deducts its percentage fee on the entire gross charge (including the surcharge).

Penalties for surcharging debit cards include immediate merchant assessment fines from payment card networks ($5,000 for first violation, escalating to $25,000/month), chargeback reversals with non-refundable dispute fees, civil lawsuits under state deceptive trade practice laws, and potential merchant account termination (MATCH list listing).

Yes. B2B businesses, manufacturing distributors, law firms, and consulting practices can legally surcharge invoices paid via credit card up to 3.0%, provided the payment terms are clearly stated on the invoice and contract, and an alternative fee-free payment method (such as ACH or corporate check) is provided.

Leading POS platforms provide purpose-built surcharge compliance settings. When enabled, the terminal reads the card's Bank Identification Number (BIN) upon insertion or tap. If a debit card is detected, the terminal automatically bypasses the surcharge prompt, protecting the merchant from federal Durbin Amendment violations.

Following the nationwide class action settlement effective October 6, 2022, Canadian merchants can surcharge credit cards up to 2.4% (or actual cost), except in the province of Quebec where Section 12 of the Consumer Protection Act strictly prohibits credit card surcharges. Surcharging Interac debit cards is illegal nationwide.

Under Article 62(4) of the EU Payment Services Directive II (PSD2) and UK Payment (Fee) Regulations 2018, surcharging on consumer credit and debit cards is completely banned across the UK and EEA. Merchants cannot add any fee for Visa, Mastercard, or Maestro consumer cards. Surcharging is only permitted on commercial/corporate business cards up to direct costs.

In Australia, the RBA Standard No. 3 and the Competition and Consumer Act 2010 ban 'excessive' payment surcharges. Australian merchants can only charge their verified 'cost of acceptance' as reflected on their merchant statement (typically ~0.5% for eftpos, 1.0%–1.5% for Visa/Mastercard). Surcharging above actual cost results in severe ACCC fines.
