The Legal Landscape: What You Need to Know (Not Legal Advice)
We’ll say it up front: we’re not lawyers.
Cash discounting is legal in all 50 states. Surcharging, however, is not legal in 6 states.
It all comes down to how fees are presented to your customers. Some states allow surcharges, others restrict them. Most importantly, there’s a clear legal difference between surcharging and cash discounting — and that’s matters most.
California has some of the strictest laws in the country when it comes to passing credit card processing costs on to customers. This legal landscape evolved significantly starting in July 2020, when Assembly Bill 1478 (AB 1478) went into effect, followed by additional clarifications through Senate Bill 478 (SB 478) and related executive actions by the governor.
AB 1478, signed into law in July 2020, largely prohibited most California businesses from adding surcharges to credit card transactions. This meant businesses couldn’t simply add a 3% or 4% fee on top of a bill when customers chose to pay by credit card.
However, recognizing the special operational needs of the restaurant industry, California later provided an exception through SB 478 and executive clarifications, explicitly allowing restaurants to continue adding surcharges, provided they follow strict disclosure rules. This means that today, restaurants in California can legally add a credit card surcharge if it’s clearly stated on the menu and the customer’s receipt.
For all other types of businesses — retail, automotive, salons, contractors, professional services, and more — surcharging remains prohibited under California law.
While surcharges are heavily restricted, cash discounting is fully legal across all industries in California. A cash discount program is structured differently: businesses list prices assuming customers will pay by card, and then offer a small discount (typically 3-4%) at checkout to customers who pay with cash or check.
This method has repeatedly been found compliant with both federal regulations and California state law, as long as it’s properly structured and clearly disclosed at the point of sale.
Some businesses try to add a general “service fee” or “non-cash adjustment.” In California, this can be risky. If the fee applies only when a customer pays by card, it’s likely considered an illegal surcharge under AB 1478. However, if it’s a general fee that applies to all customers regardless of payment method, it may be legal.
As always, the key is transparency and fairness. Fees that single out credit card use are tightly regulated.
Surcharging is generally illegal in California, except for restaurants under the specific carve-out provided by SB 478 and related clarifications.
Cash discounting remains completely legal, provided it’s implemented with clear signage and compliant systems..
Because the penalties for non-compliance can be significant, it’s wise to work with a provider (like us) who specializes in fully compliant cash discount systems — or consult with your attorney to make sure your pricing structure is safe under California law.
Look — this isn’t about squeezing more out of customers. It’s about survival.
