As credit card processing costs rise, more merchants are exploring ways to offset these fees and protect their profit margins. One increasingly common approach is implementing surcharge fees on credit card transactions. While potentially beneficial, adding surcharges requires a deep understanding of legality, customer impact, technology, and compliance.
In this in-depth guide, we’ll explain what surcharge fees are, how they differ from other pricing strategies like cash discounts, and how your business can implement a compliant and effective surcharge program. Whether you’re a brick-and-mortar store or an online merchant, knowing how to navigate surcharge rules in 2025 is key to maximizing profitability while staying within legal and card brand regulations.
What Is a Surcharge Fee?
A surcharge fee is an additional amount a merchant adds to a customer’s total when a credit card is used as the method of payment. The purpose of this fee is to recover the cost associated with credit card processing, which typically includes network fees, processor markups, and interchange charges.
Surcharges apply only to credit card transactions—not to debit cards, even if those are run as credit. Most major card networks strictly prohibit surcharges on debit or prepaid card payments.
Why Merchants Use Surcharge Fees
Businesses adopt surcharging to:
- Offset rising credit card processing costs
- Maintain price transparency while protecting margins
- Encourage customers to use lower-cost payment methods like cash or debit
Especially in industries with thin margins or high average ticket sizes, recouping these fees can have a significant financial impact.
Surcharge vs. Cash Discount: What’s the Difference?
Though similar in purpose, surcharging and cash discounting are two different strategies:
Surcharge Fee
- Adds a fee to a credit card purchase
- Must be clearly disclosed at the point of sale and on receipts
- Regulated by state laws and card brand rules
Cash Discount
- Offers a lower price to customers paying with cash or debit
- Doesn’t add fees; instead reduces the base price for cash buyers
- Typically subject to fewer regulatory hurdles
Understanding which model best suits your business depends on your goals, technology, and local laws.
Is It Legal to Add Surcharge Fees?
State Laws
As of 2025, surcharge legality varies by state. Some states prohibit surcharging, others allow it with restrictions, and some have active legal challenges pending.
Merchants must:
- Confirm surcharge legality in their state
- Understand specific notification and signage requirements
- Keep updated on legislative changes
Card Brand Rules
Visa, Mastercard, Discover, and American Express all have rules merchants must follow:
- Surcharge must not exceed the cost of processing
- Cannot exceed a maximum cap (generally 4%)
- Must be disclosed at checkout and on the customer’s receipt
- Merchant must notify the card brands and payment processor 30 days in advance
Failing to comply with card brand policies can lead to penalties, revocation of merchant accounts, or legal exposure.
How to Implement a Surcharge Program
1. Verify State and Card Brand Regulations
Check the current legal status of surcharging in your state and review the specific requirements from your card processor and each card network.
2. Notify Card Brands and Processors
Before implementation, you must:
- Provide at least 30 days’ notice to Visa, Mastercard, and your payment processor
- Ensure system readiness for surcharging
3. Update Your POS or Gateway System
Your technology must:
- Differentiate credit vs. debit payments
- Apply surcharges only to credit cards
- Display surcharge amounts clearly before checkout
- Include fees on digital and printed receipts
Most modern POS systems now offer built-in surcharge support or compatible software integrations.
4. Post Required Signage
Surcharge disclosures must be clearly posted:
- At the entrance of your business (if brick-and-mortar)
- At the point of sale or checkout
- On receipts
Online merchants must include disclosures on checkout pages prior to payment.
5. Train Staff and Monitor Compliance
Ensure your team understands how to explain surcharges to customers and handle questions. Regularly audit transactions and receipts for accuracy.

Real-World Use Cases
Retail Store
A regional electronics retailer implemented surcharges on credit card purchases over a specific threshold. Customers were informed at checkout and via signage, resulting in increased use of debit and reduced card processing expenses.
Online Services Platform
A SaaS provider added a surcharge for monthly subscriptions paid by credit card. To balance transparency, they offered ACH and debit options without added fees. This shift reduced their effective transaction costs.
