Montana Credit Card Surcharge Laws
Montana credit card surcharge laws for 2026 — no state cap or statute, where the '3% cap' myth comes from, card network rules, and alternatives.
Montana has no state law that caps or regulates credit card surcharges by merchants. Surcharging is legal in Montana, governed only by card network rules — including Visa's 3% cap on credit card surcharges. A 'Montana 3% cap' is widely repeated online, but it comes from a 2021 legislative draft (LC 350) that was never enacted, and a 2025 bill to create one (SB 528) died in committee.
Montana Code Annotated Section 7-6-617, often cited as the state's surcharge law, actually covers local government finance — it lets counties and municipalities accept card payments and charge a service fee. It says nothing about private merchants. For businesses, the rules that matter come from the card networks, not from state law.

Is Credit Card Surcharging Legal in Montana?
Yes, credit card surcharging is legal in Montana — and no state law restricts it. Montana has no surcharge statute, so merchants need only follow the card network rules — Visa caps credit card surcharges at 3% and requires clear disclosure.
A widely repeated claim holds that financial institutions and credit card companies cannot prohibit the collection of surcharge fees in Montana. That language comes from LC 350, a 2021 bill draft that was never enacted — the same text returned as SB 528 in 2025 and died in committee on May 23, 2025.
What's allowed in Montana
Montana businesses can implement credit card surcharges under these card network conditions:
- Maximum 3% surcharge - Visa's network rules cap credit card surcharges at 3%
- Pre-transaction disclosure - customers must be informed before processing payments
- All business types - merchants of all types can surcharge under card network rules
- Advance notice - your processor needs 30 days' written notice before a surcharge program begins (Mastercard also requires its web form)
- Government entity surcharges - separately, Mont. Code Ann. § 7-6-617 lets local governments charge a service fee on card payments
What's not allowed in Montana
Card network rules and federal regulations prohibit these surcharge practices:
- Exceeding 3% surcharge limit - Visa's 3% ceiling applies even though Montana sets no cap of its own
- Surcharging debit cards - prohibited by card network rules in every state
- Inadequate disclosure - failing to inform customers before processing transactions
- Post-transaction surprises - surcharges must be disclosed upfront, not after payment
- Store-branded card fees - cannot surcharge customers using the business's own credit cards
Disclosure Requirements for Montana Businesses
Card network rules require businesses to disclose surcharge fees prior to the transaction being processed. This creates transparency and ensures customers can make informed payment decisions.
Required Disclosure Elements:
- Clear notification of surcharge fees before payment processing
- Visible signage at points of sale for brick-and-mortar businesses
- Website disclosure during checkout process for online transactions
- Verbal notification for telephone transactions
- Receipt itemization showing surcharge as separate line item
Penalties for non-compliance in Montana
Montana businesses face enforcement through multiple channels:
State Law: Montana has no surcharge statute, so there is no state surcharge cap or disclosure rule to violate. Compliance exposure for Montana merchants comes from card network rules and federal requirements instead.
Card Network Penalties: Visa, MasterCard, and other networks can impose fines ranging from $1,000 to $1 million for merchants violating surcharge rules or disclosure requirements.
Federal Violations: Even with no state statute in play, businesses still must comply with federal requirements regarding debit card restrictions and proper disclosure.

- Montana Department of Justice Office of Consumer Protection

- Mail/Fax: Complaint forms available for download from the website
Is Debit Card Surcharging Legal in Montana?
No — card network rules prohibit debit card surcharging in Montana and all 50 states. These network rules bar surcharges on debit card transactions regardless of how they are processed. (Debit interchange is separately capped under the federal Durbin Amendment — the economics behind the networks' rule.)
No Montana statute addresses debit surcharges — the network prohibition is what governs. Businesses must ensure their payment systems can distinguish between credit and debit cards to avoid accidentally surcharging prohibited transactions.
This prohibition applies to all debit card types:
- Traditional PIN debit cards
- Signature debit transactions processed as credit
- Prepaid debit cards
- FSA/HSA debit cards
Where the 'Montana 3% Cap' Actually Comes From
The 'Montana 3% cap' repeated across the web is not state law. It traces to LC 350, a 2021 legislative draft that was never enacted; the same language returned in 2025 as SB 528, which died in standing committee on May 23, 2025.
Legal Hierarchy in Montana:
No state limit - Montana law sets no cap on merchant credit card surcharges
Card network limits - Visa's 3% cap is the binding ceiling for Montana merchants
Mastercard's 4% network cap - higher than Visa's; merchants accepting both brands typically stay at 3%
Practical Example: A Montana business charging a 3.5% surcharge on Visa credit cards would violate Visa's 3% network cap even though no state law applies. Enforcement would come from the card network, not the state.
That leaves Montana among the majority of states with no surcharge statute of their own — NCSL lists Montana as having none — in contrast to states that cap or ban surcharging by law.
How the Rules Apply to Different Montana Organizations
With no state surcharge statute, the rules that apply depend on the entity type:
Private Businesses: Merchants can surcharge credit cards under card network rules — up to Visa's 3% cap, credit cards only, with clear disclosure and the required advance notice.
Local Government Entities: Montana Code Annotated Section 7-6-617 — the statute often miscited as a merchant surcharge law — allows local governments to accept card payments and charge a service fee for taxes and other amounts owed to them. It does not apply to private businesses.
State Agencies: May have similar authority under related statutes, though specific provisions may vary.
Professional Service Providers: Legal professionals, healthcare providers, and other service businesses can implement surcharges following card network requirements and any applicable professional conduct rules.
