Payment processing in Arizona.
VitaPay serves merchants in Arizona, as it does in every US state. Below are the Arizona rules and official offices worth knowing before you take your first card payment there: the surcharging rule, the sales-tax agency and where the business is registered.
Adding a credit card surcharge in Arizona.
No state surcharge restriction foundNo Arizona statute restricting credit card surcharges was found, and the NFIB’s 2025 state guide and current industry summaries list Arizona as having no state-specific surcharge rule. Card network rules on notice, disclosure and limits still apply.
General information, not legal advice. Surcharging laws change, and card network rules apply in addition to Arizona law. Confirm the current rule with the state or your own adviser before adding a surcharge; the sources below show when this was last read.
