Contested — most current guides describe California as a ban state
Sources are genuinely split. A growing majority of 2026 compliance guides describe California as prohibiting credit card surcharges under SB 478 (effective July 1, 2024), the state's 'Honest Pricing' law. Other sources point to the old surcharge ban (Civil Code § 1748.1) being ruled unconstitutional and describe surcharging with disclosure as generally permitted. Restaurants have a specific SB 478 carve-out for disclosed service fees. Given the split, treat California as high-risk for a standard line-item surcharge and consult an attorney before implementing one.
California at a glance
| Credit card surcharge | Contested — most current guides describe California as a ban state |
|---|---|
| Maximum surcharge | N/A — status contested; all-in or dual pricing recommended |
| Debit & prepaid cards | Never — prohibited nationwide by federal rules and card networks, in every state |
| Cash discount / dual pricing | Legal — permitted in all 50 states with a compliant structure |
| State rule | SB 478 ('Honest Pricing,' eff. July 2024) widely described as an effective ban; old Civil Code § 1748.1 ban separately ruled unconstitutional (Cal. Civ. Code § 1748.1 (enjoined — Italian Colors v. Becerra); Cal. SB 478 (eff. July 1, 2024)) |
| Penalty | SB 478 violations: fines up to $1,000 per instance |
| Disclosure | Advertised prices must include mandatory fees under SB 478. Most current guides treat a separately added card surcharge as exactly the kind of drip-priced fee SB 478 was written to stop. Restaurants have an SB 478 exemption allowing disclosed service fees. All-in pricing or true dual pricing is the defensible structure regardless of which reading is correct. |
What California merchants need to know
California is the state where the public guidance has genuinely shifted, and it's worth being direct about that: as of mid-2026, most current compliance guides describe California as prohibiting credit card surcharges under SB 478, the 'Honest Pricing' law effective July 1, 2024 — a noticeably firmer position than the 'permitted with disclosure following court rulings' framing that was common in earlier 2024 and 2025 guidance. The older framing wasn't wrong when it was written; the practical enforcement and industry consensus around SB 478 has hardened since.
The one part of this that's stable: restaurants have a specific SB 478 carve-out permitting clearly disclosed service fees, and true dual pricing (posting both a card price and a cash price) or all-in pricing (one price that already includes acceptance cost) are treated as compliant under either reading of California law. If you operate in California, that's the practical answer regardless of which interpretation of SB 478 ultimately prevails — a line-item 'credit card surcharge' added at checkout is the structure carrying the most legal exposure right now, and this is one page where we'd tell you directly: talk to a California attorney before implementing anything beyond dual or all-in pricing.
The cash discount alternative
Wherever surcharge rules get complicated, dual pricing doesn't: posting a card price and offering a discount for cash is legal in all 50 states when it's structured correctly — the posted price must be the card price, with cash receiving a true discount. The economics match a surcharge; the compliance profile usually beats it.
California's SB 478 environment points merchants toward the cash discount / all-in pricing structure almost by default: post the card-inclusive price, discount for cash. It satisfies the all-in disclosure principle regardless of how the surcharge question is ultimately resolved.
