What an over-limit fee is on a credit card

The US opt-in rule

12 CFR 1026.56 says a card issuer shall not assess an over-the-limit fee unless it gave you a notice and obtained your affirmative consent, the opt-in, to pay transactions that go over the limit. That consent has to be separate from other signatures. Signing a credit application is not, by itself, an opt-in. A checkbox or a signature line used only for this choice can be. The issuer may still pay an over-limit transaction without your consent if it does not charge a fee. A declined purchase with no fee is allowed. An issuer that simply declines anything that would go over the limit does not have to offer the opt-in.

The opt-in lasts until you revoke it, or until the issuer stops paying over-limit transactions. The issuer must put a revocation in place as soon as reasonably practicable. Revoking does not require the issuer to reverse fees already charged for earlier transactions. If a balance stays over the limit because of a transaction from before you revoked, a later cycle can still be charged under the rest of the rule. Joint account holders: any one joint consumer's consent counts, and any one joint consumer's revocation counts. An authorized user who is not jointly liable does not opt the account in.

The same section limits how often the fee can be charged. Not more than one over-limit fee per billing cycle. Not more than three billing cycles for the same over-limit transaction, unless another over-limit transaction happens in the way the rule describes for the last two cycles. The issuer cannot charge the fee for a cycle in which the limit was not actually exceeded. It cannot condition your credit limit on opting in. It cannot charge an over-limit fee if the limit was exceeded solely because of fees or interest imposed as part of the plan during that cycle. The regulation's examples use round dollar amounts to illustrate the timing. Those examples are not a typical fee and they are not your credit limit. This guide does not repeat them as prices.

What to look for on the statement

The fee has its own name, often over limit or over-the-limit fee, in the fees section. The purchase that crossed the limit is a different line. Write down both. If you never opted in, a fee on a US consumer card is the thing to ask about, with the date and the amount. The issuer can say the consent is on file. Ask when you opted in and how to revoke it. Revoking stops future fees under the rule. It does not erase a fee the rule still allows for an older transaction. How to ask is on how to ask your bank to refund a fee. A purchase you did not make is dispute a charge in the US, which is a different problem from a fee on a purchase you did make.

Going over the limit can also be interest and fees, not a new shopping trip. If the only reason you crossed the limit is fees or interest the issuer added that cycle, the US rule above says the over-limit fee itself should not be charged. Interest on the balance is still a separate topic, on credit card interest. A late fee is on US credit card late fees.

Canada

Canadian issuers are not covered by the US opt-in section. The amounts printed by RBC, Scotiabank, BMO, CIBC, and one TD card are on credit card fees by bank (Canada), opened 16 October 2026. On that page, Scotiabank, BMO, and the TD Cash Back Visa Infinite box each print $29.00, and CIBC prints $29, with the exceptions those documents state, including Quebec on several of them and a CIBC exception for Visa Infinite Privilege. The RBC page in that table does not print an overlimit dollar. American Express Canada was left out of that table because the pages opened that day did not print the dollar. Use the Canada page for the full cell, including cash advance and returned payment columns. Do not assume a US opt-in story applies to a Canadian card.

A card dispute in Canada is on dispute a charge in Canada. Asking the issuer to remove one over-limit fee is still a request. They can say no. The agreement and the information box control the number, not this page.

Upload the statement on Expenvo. The PDF stays on your device. Expenvo lists bank fee lines it recognizes so you can see the date, the name, and the amount before you call. It does not call the bank, and it does not promise a refund. How to ask is on how to ask your bank to refund a fee.

Questions

Can a US issuer charge an over-limit fee if I never opted in?

No. Regulation Z says the issuer needs a segregated notice and your affirmative consent before it assesses the fee. It may still decline the transaction, or pay it without charging a fee.

How many over-limit fees can one US billing cycle have?

Not more than one per billing cycle. The same over-limit transaction cannot be charged for more than three billing cycles, unless another over-limit transaction occurs in the way the rule describes.

Where are the Canadian dollar amounts?

On the Canada credit card fees page, opened 16 October 2026. Several banks print $29. The RBC page in that table does not print an overlimit dollar. Quebec and card-family exceptions are on that page.
