Frequently Asked Questions
Yes, all Cashbizly payment calculators and compliance tools are 100% free with no registration or credit card required. You can print and share results directly with your processor or legal advisor.
Our tools integrate the verified 2026 50-state legal matrix. If your state prohibits surcharges (such as Connecticut, Massachusetts, or Puerto Rico), the surcharge calculator alerts you immediately and provides dual-pricing cash discount alternatives.
Under Visa and Mastercard network rules effective in 2026, the maximum surcharge is capped at 3.0% (reduced from 4.0% in 2023) or your actual merchant cost of card acceptance, whichever is lower. Certain states like Colorado impose a lower 2.0% statutory cap.
No. Federal law (the Durbin Amendment) and major card brand rules strictly prohibit surcharges on debit card and prepaid card transactions, regardless of whether the transaction is processed as signature credit or PIN debit.
Educational content, not legal advice. Cashbizly is an independent educational resource. Nothing here is personalized legal advice and it does not replace a licensed attorney or your state’s Attorney General.
Our state-by-state status reflects the consensus of published 2025–2026 compliance guides (card-network rules, LawPay, Stax, NCSL) as of the “last verified” date on each page. Surcharge law changes frequently and is actively litigated — always confirm current figures with your state Attorney General or a professional. Read our full disclaimer.
