Legal — no state restriction
Washington permits surcharges up to the merchant's actual cost of acceptance or the card network cap (3% for Visa), whichever is lower. No additional state-specific restriction beyond that.

What Washington merchants need to know
Washington is among the majority of states with no law limiting a merchant's ability to add a credit card surcharge. The rules that apply come entirely from the card networks, not the state capitol: the surcharge can't exceed your actual cost of acceptance (never more than 3% if you accept Visa), it applies to credit cards only — never debit or prepaid, even when a debit card is run as 'credit' — and it must be disclosed at the entrance, at the register, and on the receipt.
Washington permits surcharging up to the merchant's actual cost of acceptance or the card network cap, whichever is lower — functionally the same standard most permissive states follow, just stated a bit more explicitly in Washington guidance. Washington also has no state income tax, part of its broader reputation as a business-friendly state for small operators.
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.
Because Washington has no surcharge-specific restriction, the choice between surcharging and a cash discount program comes down to what fits your business and customers, not legal risk — both are compliant here.
