The one hard ceiling that exists, and it is a percentage rather than a dollar amount. 12 CFR 1026.52(a)(1) provides that "the total amount of fees a consumer is required to pay with respect to a credit card account under an open-end (not home-secured) consumer credit plan during the first year after account opening must not exceed 25 percent of the credit limit in effect when the account is opened," and adds that an account is considered open no earlier than the date the consumer may first use it to engage in transactions. Paragraph (a)(2) excludes two things from the cap: late payment fees, over-the-limit fees and returned-payment fees, and any fee the consumer is not required to pay. Paragraph (a)(3) makes clear the cap authorizes nothing that is otherwise prohibited.
Two features of that rule decide where it bites. It runs off the credit limit, so it constrains a small-limit account tightly and a large-limit account hardly at all. And it applies to the first year only, so it is a rule about the cost of getting in rather than a cap on what a card may charge over time.
A related disclosure sits alongside it and contains a trap. Under 12 CFR 1026.60(b)(14) and its twin at 1026.6(b)(2)(xiii), where required fees for issuance or availability plus any required security deposit charged at opening come to 15 percent or more of the minimum credit limit for the card, the issuer must disclose the available credit remaining after those amounts are debited. The threshold is measured against the card's minimum credit limit, not against the applicant's own limit. 1026.6(b)(2)(xiii) says so expressly: "the determination whether the 15 percent threshold is met must be based on the minimum credit limit for the plan. However, the disclosure provided under this paragraph must be based on the actual initial credit limit provided on the account." On a card where every account gets the same limit the two are equal and the distinction is invisible, which is exactly how it gets misapplied to a card where they differ. The same paragraph also requires the creditor to disclose that the consumer "has the right to reject the plan and not be obligated to pay those fees or any other fee or charges until the consumer has used the account or made a payment on the account after receiving a periodic statement."
The prohibition most summaries miss entirely: an annual fee may not simply be raised. 12 CFR 1026.55(a) provides that, except under the exceptions in paragraph (b), "a card issuer must not increase an annual percentage rate or a fee or charge required to be disclosed under § 1026.6(b)(2)(ii), (b)(2)(iii), or (b)(2)(xii)" on a credit card account. The first of those cross-references is the fees-for-issuance-or-availability paragraph, so the annual fee sits inside a substantive prohibition on increases, not merely inside a notice requirement.
Two of the exceptions matter here, and both carry limits worth knowing. The temporary fee exception at 1026.55(b)(1) permits an increase "upon the expiration of a specified period of six months or longer," but only where the issuer disclosed in writing beforehand, clearly and conspicuously, both the length of the period and the fee that would apply after it. A fee waived for three months and then charged cannot be raised on that route at all. The advance notice exception at 1026.55(b)(3) permits an increase after the issuer complies with the notice requirements in 1026.9, and 1026.55(b)(3)(iii) puts a hard fence around it: that exception "does not permit a card issuer to increase … a fee or charge required to be disclosed under § 1026.6(b)(2)(ii) … during the first year after the account is opened, while the account is closed, or while the card issuer does not permit the consumer to use the account for new transactions." So an annual fee on a new account cannot be increased in year one by giving notice, and an issuer that has stopped letting you transact cannot raise it either.
What the notice route then requires, which takes four paragraphs to state and is why almost nobody states it correctly. The chain runs like this.
12 CFR 1026.9(c)(2)(ii) defines a "significant change in account terms" as, among other things, a change to a term required to be disclosed under 1026.6(b)(1) and (b)(2). The annual fee is disclosed under 1026.6(b)(2)(ii), so an increase in an annual fee is a significant change in account terms.
1026.9(c)(2)(i)(A) then requires the creditor to "provide a written notice of the change at least 45 days prior to the effective date of the change" to each consumer who may be affected.
1026.9(c)(2)(iv)(B) requires that notice on a credit card account to state that the consumer has the right to reject the change before its effective date, and 1026.9(h)(1) gives effect to that right: the consumer "may reject that change by notifying the creditor of the rejection before the effective date of the change."
1026.9(h)(2) says what rejection does. The creditor "must not: (i) Apply the change to the account; (ii) Impose a fee or charge or treat the account as in default solely as a result of the rejection; or (iii) Require repayment of the balance on the account using a method that is less beneficial to the consumer than one of the methods listed in § 1026.55(c)(2)."
And here is the half that makes the right honest rather than a free option. 1026.9(c)(2)(iv)(B)(3) requires the notice to include, if applicable, "a statement that if the consumer rejects the change or changes, the consumer's ability to use the account for further advances will be terminated or suspended." So rejecting an annual-fee increase can cost the use of the card while leaving the existing balance to be repaid on the protected terms. The right is a right to decline a repricing, not a right to keep the card at the old price. Separately, 1026.9(h)(3) switches the whole of paragraph (h) off "when the creditor has not received the consumer's required minimum periodic payment within 60 days after the due date for that payment," so a seriously delinquent account has no rejection right at all.
The exception that covers the situation people most expect to be protected in. 12 CFR 1026.9(c)(2)(v)(B) provides that no change-in-terms notice is required "when the change is an increase in an annual percentage rate or fee upon the expiration of a specified period of time," subject to three conditions that must all be met: before the period began, the creditor disclosed in writing and in a clear and conspicuous manner both the length of the period and the rate or fee that would apply after it; those two disclosures were "set forth in close proximity and in equal prominence to the first listing" of the rate or fee applying during the period; and the rate or fee that applies afterwards does not exceed what was disclosed.
Read against a real offer, that means the "annual fee waived for the first year" card which starts charging in year two triggers no 45-day notice and no right to reject, because the year-two fee was disclosed up front and nothing changed. The fee arriving is the disclosed term operating, not a change to it.
A separate notice is owed every year the fee renews, and it has to tell you how to get out. This is the provision most easily missed, because it sits three subsections away from the change-in-terms machinery. 12 CFR 1026.9(e) requires a card issuer that "imposes any annual or other periodic fee to renew a credit or charge card account of the type subject to § 1026.60, including any fee based on account activity or inactivity," to mail or deliver written notice of the renewal to the cardholder. The timing is set by the regulation: the notice must come "at least 30 days or one billing cycle, whichever is less, before the mailing or the delivery of the periodic statement on which any renewal fee is initially charged to the account." And its required contents include the application-table disclosures that would apply on renewal, plus, where applicable, "how and when the cardholder may terminate credit availability under the account to avoid paying the renewal fee." The notice may be made on or with a periodic statement, which is why it is so often read as ordinary statement furniture rather than as a deadline.
Why the fee is invisible in the APR. An annual percentage rate on a credit card is essentially the annualized interest rate, and it does not fold in an annual fee. That is the opposite of the position on a closed-end loan such as a mortgage, where the APR does capture certain financing costs, which is why "compare the APR" is sound advice on a mortgage and incomplete advice on a card. The consequence for this page is simple: the fee has to be compared separately, and no single advertised number contains it.
