Can I charge customers a credit card fee? Rules, limits & how to do it right
Surcharges, convenience fees, state laws, and network rules (Visa/Mastercard) — everything you need to know before adding a fee at checkout.
Short answer: Yes, in most U.S. states you can charge customers a fee for paying with a credit card. The fee is capped at 4% (or your actual processing cost, whichever is lower). You must notify the card networks (Mastercard, Visa) and clearly disclose the surcharge at checkout and on the receipt. Debit cards and prepaid cards are excluded from surcharging. 11 states still have restrictions — see full map below.

🔁 Surcharge vs convenience fee — what’s the difference?
Many people use the terms interchangeably, but card network rules and state laws treat them differently. According to Bankrate and Stripe:
| Fee type | Definition | Where allowed | Typical % |
|---|---|---|---|
| Surcharge | Extra fee for using a credit card as a payment method (any transaction) | Legal in 39 states (with rules) | up to 4% |
| Convenience fee | Fee for using an alternative payment channel (e.g. paying by phone for an online store) | All 50 states | usually 2–3% |
“A convenience fee is only allowed if the payment channel is not standard for the business — and there must be an alternate fee‑free way to pay.” (Stripe resource)
🗺️ Where is credit card surcharging legal? (2026 update)
Based on Bankrate and NCSL (National Conference of State Legislatures), here is the current landscape. Eleven states have restrictions or bans (though some bans have been challenged).
States with active restrictions (as of Feb 2026): Connecticut, Massachusetts, Maine. Also Colorado, Kansas, Oklahoma have had partial restrictions — always verify locally.
Even in states where surcharging is legal, you cannot surcharge debit cards or prepaid cards (Mastercard, Visa rules). Also, some states like New York require specific signage.
💳 Mastercard & Visa surcharge rules (the compliance must‑read)
Mastercard’s official merchant surcharge page details the requirements. Visa has similar rules. Here’s the summary:
Mastercard key provisions (effective 2013 / current)
- Cap: surcharge ≤ 4% or your effective discount rate, whichever is lower.
- Registration: merchant must notify acquirer and Mastercard 30 days before starting. (Mastercard registration link)
- Disclosure: clear signage at point of entry and checkout; dollar amount on receipt.
- No surcharge on Debit Mastercard / prepaid.
- If you accept American Express or Discover, you must also follow their rules (often they prohibit surcharging).
What Visa says
Visa caps surcharges at 3% (for credit) and also requires registration via the acquirer. Merchants must treat all card brands equally – you cannot single out Visa if you also accept Amex (unless you surcharge all).
💰 How much can you actually charge a customer?
The maximum is the lower of: your effective processing cost (what you pay Stripe, Square, etc.) OR 4% (Mastercard) / 3% (Visa). Most merchants just use a flat 3% to stay compliant with both.
| Transaction amount | Typical 3% surcharge | You receive (after fee) |
|---|---|---|
| $20.00 | +$0.60 | $20.00 (if you pass fee) |
| $50.00 | +$1.50 | $50.00 |
| $127.50 | +$3.83 | $127.50 |
| $1,000.00 | +$30.00 | $1,000.00 |
Remember: you cannot charge more than your actual processing fee. If your effective rate is 2.2% + 10¢, you must cap the surcharge at that amount (not 3%).

📋 How to start charging credit card fees (5 steps)
- Check your state law — use the map above. If you’re in CT, MA, ME, consult a lawyer (or consider a convenience fee instead).
- Review your processor agreement — Stripe, Square, etc. allow surcharging? (Stripe supports it with Radar or via third‑party apps).
- Notify Mastercard/Visa — at least 30 days before. Mastercard has an online form; Visa requires you to inform your acquirer.
- Display clear disclosure — at store entrance, at checkout, and on the receipt (dollar amount).
- Apply surcharge only to credit cards — exclude debit/prepaid (technically you must not surcharge them).
“If you plan to add a surcharge, make sure your customers know about it before they check out to avoid sticker shock and potential chargebacks.” (Experian blog)
