As a business attorney and template designer with over 12 years drafting payment and liability documents for U.S. companies, I have created and refined hundreds of credit card on file authorization forms for clients ranging from e-commerce stores to medical practices and property management firms. Today I'm giving you my most popular, attorney-reviewed credit card authorization form template completely free – available in editable Word, fillable PDF, and Google Docs formats.
This simple credit card authorization form is designed to protect your business under U.S. payment card industry rules while remaining easy for customers to understand and sign. Download it at the bottom of this page.
A credit card authorization form (sometimes called a credit card on file authorization form or payment authorization form) is a written document that gives a merchant explicit permission to charge a customer's credit or debit card for a specific amount or on a recurring basis. According to the card brands (Visa, Mastercard, Amex, Discover), obtaining written authorization is the safest way to defend against chargeback claims when you store or charge a card later.
In my experience, businesses that skip a proper standard credit card authorization form lose 70-80% of chargebacks they fight because they cannot prove the cardholder agreed to the charge. A signed form dramatically improves your representment success rate.
Common situations requiring a credit card authorization template:
Based on PCI DSS requirements, card brand rules, and Regulation E, your form should contain:
| Element | Why It's Required | Source |
|---|---|---|
| Full cardholder name & billing address | Verifies identity and reduces fraud | Visa Cardholder Dispute Guide |
| Complete card number OR last 4 digits + token reference | PCI compliance – never store full CVV | PCI DSS Requirement 3.4 |
| Expiration date | Needed for processing | All card brand rules |
| Exact amount(s) or “amount not to exceed” | Prevents unauthorized charges | Reg E §1005.10 |
| Description of goods/services | Cardholder must know what they're approving | Mastercard Dispute Guide |
| Recurring vs one-time language | Specific rules for ongoing authority | Visa Rules 5.4.3 |
| Clear cancellation/refund policy | Required disclosure | FTC & state laws |
| Wet or electronic signature + date | Proof of authorization | E-SIGN Act |

Step-by-step instructions I give all my clients:
I included two separate paragraphs in the template:
One-time or “card on file” version: “I authorize [Business] to charge the credit card listed above for the amount indicated, including any additional fees for damages, no-shows, or services rendered up to $[maximum amount].”
Recurring version: “I authorize [Business] to charge the credit card above according to the terms below on a recurring monthly basis until I cancel in writing…” (includes NACHA-compliant cancellation language).
Many businesses now accept both credit cards and bank (ACH) payments. I created a combined credit card ACH authorization form that satisfies both card brand rules and NACHA Operating Rules in a single two-page document. This is especially popular with gyms, childcare centers, and coworking spaces.

After 12 years of audits, here are my top storage rules:
Is a verbal OK enough in 2025?
No. Card brands require written (paper or electronic) authorization for card-on-file and future charges.
Can I use Square's built-in form instead?
Square's saved card feature includes authorization, but many merchants still use a separate Square credit card authorization form for non-Square charges (e.g., phone orders).
Do I need a new form every year?
Only if the card expires or the customer requests changes. Most merchants keep one on file indefinitely until cancelled.
Is this template compliant in all 50 states?
Yes for federal and card-brand rules. A handful of states have minor additional disclosures (included as optional paragraphs).
