The short answer
In most states, yes, on credit cards only. Visa caps a surcharge at your processing rate or 3%, whichever is lower, requires 30 days' notice to your acquirer, and bans surcharges on debit and prepaid cards. Connecticut, Massachusetts, Maine and Puerto Rico ban surcharges; Colorado and Oklahoma cap them. A cash discount is protected by federal law.
Can You Legally Charge Customers a Credit Card Fee?
Usually, within the rules. Visa says merchants in most states "may add a surcharge to credit card transactions," subject to its requirements, and a handful of states ban or limit the practice. State law is checked against each statute below, as of October 7, 2026. For the October 2026 ban in the news, which is Australian, and the New Jersey and New York rules, see is there a credit card surcharge ban in October 2026.
What Are Visa's Surcharge Rules?
Visa's US rules are specific.
- Notice: "Merchants must notify their acquirer 30 days before they begin surcharging."
- Credit only: "debit cards and prepaid cards cannot be surcharged."
- Cap: your merchant discount rate for the card or 3%, whichever is lowest.
- Disclosure: signs at the point of entry and point of sale, and the surcharge on every receipt.
- Enforcement: the acquirer of a merchant surcharging improperly may be "assessed an immediate US $1,000 fine."
Which States Ban or Limit Credit Card Surcharges?
States change these rules, so check your own state's current law before you start.
| State | Rule | Law |
|---|---|---|
| Connecticut | No surcharge on any transaction; discounts for cash or debit allowed | Conn. Gen. Stat. ch. 739 |
| Massachusetts | No surcharge for using a credit card | M.G.L. c.140D, s.28A |
| Maine | No surcharge for using a credit or debit card | 9-A M.R.S. s.8-509 |
| Puerto Rico | No surcharge | Ley 150-2008 |
| Colorado | Capped at 2% of the total, or the merchant discount fee, at the seller's choice; signage required | SB21-091 |
| Oklahoma | Allowed since Nov. 1, 2025; capped at 2% or the actual processing cost, whichever is less | SB 677 (2025) |
| Louisiana | No surcharge on debit cards, from Aug. 1, 2026 | Act 751 (2026) |
Can You Add a Fee to Debit Card Payments?
No. Visa bans surcharging debit and prepaid cards everywhere in the US, and Maine and Louisiana write it into state law: Louisiana's new law says a retail business "shall not impose a surcharge on a cardholder who uses a debit card."
Is a Cash Discount Different From a Surcharge?
Yes, and it is protected. Federal law bars card networks from rules that "inhibit the ability of any person to provide a discount or in-kind incentive for payment by the use of cash, checks, debit cards, or credit cards," provided the discount is offered to all buyers and disclosed clearly. Even Connecticut's ban allows a discount for paying by cash, check or debit.
The difference is how the price is built: a cash discount takes money off the posted card price; a surcharge adds a fee on top. Compare them in cash discount vs surcharge. BatchOut sets up either, inside the rules for your state.
