Credit card surcharge in Washington: the 2026 rules
Yes, a credit card surcharge is legal in Washington right now. The card networks set the terms: credit cards only, capped at their limit, disclosed before payment, and itemized on the receipt. Here is the current rule set, how it differs from dual pricing and a cash discount, and what it's worth to a Washington business.
The four rules that matter
Credit cards only
Debit and prepaid cards can never be surcharged. That holds even when the customer picks 'credit' at the terminal. The terminal must spot the card type. It must apply the surcharge only where that is allowed.
Capped, twice
The surcharge can't exceed the network cap: 3% on Visa, 4% on Mastercard. And it can't exceed your actual cost of credit acceptance. The lower of the two wins.
Disclosed before payment
Posted notice at the door and at the register, before the customer commits. Surprise is the thing the rules exist to stop.
Itemized on the receipt
The surcharge appears as its own labeled line with the amount. No blending it into the price after the fact.
Surcharge, dual pricing, or cash discount: how they differ
Surcharging keeps one posted price. It adds the disclosed cost to credit sales only, on top of the price. It fits where credit is most of the volume, like B2B and professional services. It leaves the debit cost on you, because debit cannot be surcharged. See how a surcharge program is set up, and what Washington businesses pay to accept cards for the numbers behind it.
Dual pricing posts a cash price and a card price before the sale. The customer chooses. The program covers all card types, including debit, which is why counter businesses with mixed card use often prefer it. A cash discount program looks similar at the register but is framed as a discount off the card price rather than a fee added to it. The receipt math ends up close; the framing and the paperwork differ.

What it's worth: a real example
We have read 36 recent statements from Washington businesses that switched to a compliant surcharge or dual pricing program. The average business kept over $1,000 a month that used to go to card fees. That is not a projection; it is what showed up on the next statement once the cap, the disclosure, and the receipt line were set up correctly.
The number moves with your card mix and your ticket size, which is exactly why we read your statement line by line before recommending a program. Businesses in Federal Way and across Puget Sound send us one recent statement for a free rate analysis; we tell you the real number for your business before you change anything.
The part nobody should DIY
Every rule above is enforced at the terminal. It spots the card type, holds the cap, prints the receipt line. A program set up wrong works fine right up until it doesn't. Ours ship set up, with the signs in the box. That is why this page can be short.

Fair questions
Is a credit card surcharge legal in Washington in 2026?
Yes. Washington has no state law against surcharging, and the card networks (Visa, Mastercard, Discover, Amex) allow it under their own rules: credit cards only, capped, disclosed before payment, and itemized on the receipt. No state law has changed that in 2026.
Who can set up a compliant surcharge or dual pricing program in Washington?
A local merchant services broker who does this daily. Northwest Payment Brokers, based in the Seattle-Tacoma area, sets up surcharge and dual pricing programs for Washington businesses and handles the parts that trip up a DIY setup: the 30-day network notice, the cap, the debit exclusion, the signage, and the receipt line. Send one recent statement for a free rate analysis and we tell you which program fits before you switch.
Can I surcharge debit cards in Washington?
No, nowhere in the U.S. Network rules prohibit surcharges on debit and prepaid cards even when they're run as credit. This is the rule most DIY setups get wrong.
How much can the surcharge be?
No more than your actual cost of credit acceptance, and never above the network cap: Visa limits credit card surcharges to 3%, Mastercard to 4%. Whichever number is lower, that's your ceiling. We set the cap on the terminal, so the register can't get it wrong.
What disclosure is required?
You need a clear notice at the entrance and at the point of sale, before payment. The surcharge also has to show as its own line on the receipt. We supply compliant signs with every setup.
What's the real difference between surcharging, dual pricing, and a cash discount?
Surcharging keeps one posted price and adds a disclosed fee only on credit sales. Dual pricing posts two prices, cash and card, before the sale, and covers every card type including debit. A cash discount also posts one card price but frames the cash option as a discount off it. All three are permitted in Washington. Which one fits depends on your card mix and your counter.
What happens if a setup breaks the rules?
Card brands can fine or shut down acceptance, and customers complain to the issuer. The fix is cheap: set it up correctly the first time, which is the part we do.
