2. What the rules say

Plain-English summary as of November 1, 2026. Rules change; verify current rules with the card networks, your state and your own advisor. Not legal or tax advice.

For gas & convenience

• Federal law allows merchants to offer discounts for payment by cash, check or debit, which is why separate cash and credit fuel prices are common. State fuel-price posting rules still apply. Sources: 15 U.S.C. § 1693o-2 (discounts for cash, check and debit); Find your state attorney general (NAAG).
• Pay-at-pump transactions use network rules for automated fuel dispensers, including pre-authorization amounts and completion timing. Sources: Visa Core Rules (public); Mastercard Rules.

Surcharges, cash discounts and debit (all industries)

• Surcharges under card-network rules apply to credit cards only, never to debit or prepaid cards, even when a debit card is run as credit. Sources: Visa: merchant surcharging and fees; Mastercard: merchant surcharge rules.
• Network rules generally require advance notice to the network or your provider, disclosure at the store entrance (or first page online) and at checkout, and the surcharge shown as a separate receipt line. Network caps sit around 3% and may not exceed your cost of acceptance; confirm the current cap in the network rules. Sources: Visa Core Rules (public); Mastercard Rules.
• Some states ban or cap surcharges, and some state laws have been challenged in court, so the current rule in your state may differ from what you've read. Check your state attorney general's office and get advice before you start. Source: Find your state attorney general (NAAG).
• A cash discount (a lower price for cash or other non-card payment) is treated differently from a surcharge. Federal law lets merchants offer discounts for paying by cash, check or debit, and networks allow properly disclosed discount and dual-pricing programs. Signage and receipts still must be accurate. Source: 15 U.S.C. § 1693o-2 (discounts for cash, check and debit).
• Debit interchange for large issuing banks is capped under the Federal Reserve's Regulation II, which is one reason debit usually costs less than credit. Source: Federal Reserve: Regulation II (debit interchange).
• Card-interchange litigation: a proposed settlement between merchants and the major card networks has only preliminary court approval. Nothing changes for merchants until final approval is granted and the networks implement new rules. Source: Consumer Financial Protection Bureau.
