Legal — but sources describe the rule inconsistently
Hawaii permits credit card surcharges under Senate Bill 470 HD2. Some older guidance describes a broader ban tied to using a surcharge 'in place of cash' — that framing describes standard differential-pricing mechanics, not a Hawaii-specific prohibition. Card network rules (3% cap, disclosure) govern in practice.
Hawaii at a glance
| Credit card surcharge | Legal — but sources describe the rule inconsistently |
|---|---|
| Maximum surcharge | 3% (card network cap — no additional state cap) |
| 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 | Surcharging authorized under SB 470 HD2 (Haw. SB 470 HD2) |
| Disclosure | Card network rules: post notice at store entry and point of sale, show the surcharge as a separate line item on every receipt. |
What Hawaii merchants need to know
Hawaii permits credit card surcharging under SB 470 HD2, and in practice merchants follow the same card network rules as most other states: 3% practical cap, credit cards only, clear disclosure. You'll find some older guides describing Hawaii as prohibiting surcharges when used 'in place of cash or check' — that language is describing the general mechanic of differential pricing (charging more for one payment method than another), which is a normal part of how any surcharge works, not a Hawaii-specific restriction on top of it.
Because sources describe this state inconsistently, if you're setting up a surcharge program in Hawaii, it's worth a quick confirmation with your processor or an attorney that your specific structure aligns with SB 470 HD2's requirements before you go live — the substance is permissive, but the framing varies enough across guides that a direct check is worthwhile.
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.
Given the mixed framing in public guidance, some Hawaii merchants choose cash discount programs simply for the clean, universally-recognized compliance story — dual pricing is unambiguous everywhere, including Hawaii.
