Tips, Service Charges, and Card Fees for California Restaurants

California restaurant card fees and tips have become a genuine source of confusion since 2024, and it is not the operators' fault. The state passed a junk-fee law, then amended it for restaurants, while the card networks kept their own surcharge rules, and payroll and tax rules for tips never changed. The result is three different kinds of money on a single check, each governed by a different set of rules. This post separates them. Nothing here is legal advice; confirm the current rules with counsel and your processor before changing your menu or your POS.

Three kinds of extra money on a check

• Tip (gratuity): voluntary, left by the guest, belongs to employees under California law. Employers may not take any portion, and the state does not allow a tip credit against minimum wage.
• Service charge: mandatory, set by the restaurant, belongs to the restaurant unless you choose to distribute it. It is revenue, taxable as such, and subject to disclosure rules.
• Surcharge: an additional fee specifically for paying with a credit card. Governed by card-network rules and, in California, by the same junk-fee statute.

Each of these hits your processing statement differently, and each generates a different kind of dispute when a guest is surprised.

SB 478 and the restaurant carve-out

SB 478 took effect in July 2024 and requires that the price advertised for a good or service include all mandatory fees. Shortly before it took effect, the legislature passed a follow-on measure that allows restaurants and similar food-service businesses to charge mandatory service fees as long as they are clearly and conspicuously displayed on the menu or wherever prices are shown. The practical upshot: a "20% service charge" can exist, but it must be visible before the guest orders, not discovered on the check. Check the current text of both statutes, because the details on what counts as conspicuous disclosure matter.

What SB 478 does not do is let you hide a card surcharge in the fine print. If you add a percentage for card payment, that is a mandatory fee for card-paying guests and the disclosure rules apply.

Card-network surcharge rules

Visa and Mastercard permit credit-card surcharges under conditions: the surcharge cannot exceed your actual cost of acceptance up to a network cap (check the current cap), you must disclose it at the entrance and at the point of sale, and it must appear as a separate line item on the receipt. You may not surcharge debit or prepaid cards, even when a debit card is run as credit. Your processor may require advance notice before you begin surcharging. If a guest disputes a surcharge and your signage was inadequate, you will likely lose the dispute and may hear from the network.

Many California operators have concluded that a menu-disclosed service charge is simpler to administer than a card surcharge, because it applies to everyone regardless of tender and avoids the debit-card problem. Others prefer to raise menu prices and skip both. There is no single right answer; it depends on your margins, your guests, and your tolerance for explaining the check.

How tips flow through your processor

For sit-down service, the card is authorized for the meal amount and the tip is added afterward. That requires tip adjustment support from your processor and POS, and the final captured amount will differ from the authorization. Interchange is charged on the total including the tip, so a 20% tip raises your processing cost by roughly 20% on that ticket. This is normal and unavoidable. What you can control is whether the processor's markup is a transparent interchange-plus figure or a flat rate that quietly overcharges on tip-inflated tickets. Pass-through pricing shows you the network cost and the processor's fee separately, which makes the tip effect visible.

Counter-service and QR-code ordering usually capture the tip at the time of sale, which avoids the adjustment step. Either way, tips must be paid out to employees on the normal payroll cycle; the processor's settlement timing (1-2 business days for cards) does not change your obligation.

Service charges and payroll

A mandatory service charge is restaurant revenue. If you distribute it to staff, it is wages, not tips, with the payroll tax treatment that implies. Some operators use service charges specifically to fund back-of-house pay, which tips cannot legally do in the same way. This is a payroll and tax question more than a payments question, so involve your accountant.

Chargebacks and guest surprise

The most common restaurant disputes are "I did not authorize this amount" (tip adjustment larger than the guest remembers) and "I was not told about the fee". Both are prevention problems. Print the service charge on the menu and the receipt, print the surcharge as its own line, have the guest sign or confirm the tip where practical, and keep the itemized ticket for at least the network's dispute window. Keep your dispute ratio well below the 0.9%-1% range where monitoring begins; restaurants rarely get there, but a busy weekend with a POS misconfiguration can produce a cluster.

What to ask your processor

Ask whether they support tip adjustment and how long after authorization it is allowed. Ask whether they will register you for surcharging and what signage they require. Ask for a written fee schedule so you can calculate your true cost of acceptance, which you need in order to set a compliant surcharge. And ask whether your POS integration handles service charges as a separate line for sales-tax purposes. The restaurants that get this right tend to be the ones that decided, deliberately, which of the three kinds of extra money they want on the check, and then disclosed it plainly.
