When a payment actually becomes late. Regulation Z sets out the mechanics with unusual specificity, and several of the provisions are protections a cardholder can use.
Under 12 CFR 1026.10(a) a creditor "shall credit a payment to the consumer's account as of the date of receipt," subject to the reasonable requirements in paragraph (b). Under 1026.10(b)(2)(ii) a creditor may set reasonable cut-off times for payments received by mail, electronically, by telephone and in person, "provided that such cut-off times shall be no earlier than 5 p.m. on the payment due date at the location specified by the creditor." The one exception concerns in-person payments: 1026.10(b)(3)(i) allows a card issuer that is a bank, savings association or credit union to impose an earlier cut-off for payments made at a branch, if that branch closes before 5 p.m.
Three further provisions are worth knowing because they hand a cardholder an argument. Under 1026.10(d)(1), where a creditor does not receive or accept payments by mail on the due date, it "may generally not treat a payment received the next business day as late for any purpose," although 1026.10(d)(2) qualifies that for payments made by other methods on the due date. Under 1026.10(b)(4)(i), where a creditor accepts a payment that does not conform to the requirements it has published, it must credit that payment within five days of receipt. And under 1026.10(f), if the issuer makes a material change to its payment address or procedures and that change causes a material delay in crediting during the following 60 days, it "may not impose any late fee or finance charge for a late payment" during those 60 days. Separately, 12 CFR 1026.5(b)(2)(ii)(A)(2) requires an issuer not to treat as late, for any purpose, a minimum payment received within 21 days after the statement disclosing that due date was mailed or delivered.
There is also a rule about how you are allowed to pay: 1026.10(e) prohibits a card issuer from charging a separate fee for using any particular payment method unless that method "involves an expedited service by a customer service representative of the creditor."
The ladder, in order, with each rung's owner named. This sequence is the reason the page exists, because almost nobody has the timing right.
Day one. A late fee may be imposed under the account agreement, and the interest-free grace period is lost, so purchases made in the next cycle begin accruing interest from their transaction dates rather than after the following due date.
The next statement. Interest appears on the balance carried and on the new purchases the lost grace period exposed. That second component is usually the larger of the two, and it is covered on the grace period page.
Thirty days. This is the first point at which the account can be reported past due, because delinquency reaches the credit file in 30-day bands. Until then the reported status for the cycle is generally current.
Sixty days. A minimum payment not received within 60 days of its due date opens the delinquency exception in 12 CFR 1026.55(b)(4), which permits the issuer to raise the rate on the existing balance, and requires the increase to cease once it receives six consecutive minimum payments on or before the due date. The credit card page carries that rule in full.
A hundred and eighty days. The territory where a creditor charges the account off in its own accounting and typically sells or refers it. That is the charge-off page's subject, and note that charging off is an accounting event rather than forgiveness of the debt.
On the fee, the honest answer is a standard rather than a number. 15 USC 1665d requires that a penalty fee be reasonable and proportional to the violation, and Regulation Z implements that partly through safe-harbor amounts an issuer may rely on. Those amounts have been the subject of rulemaking and litigation, including a 2024 rule vacated by a federal court in April 2025, and the codified figures currently render inconsistently across official sources, so no dollar figure belongs on this page. What must not be concluded from that is that no federal limit applies. 12 CFR 1026.52(b) requires a penalty fee to satisfy both paragraph (b)(1) and paragraph (b)(2), and (b)(2) is unaffected by the vacatur. Under (b)(2)(i)(A) an issuer must not impose a fee "that exceeds the dollar amount associated with the violation," which for a late payment means the minimum payment that was due; under (b)(2)(i)(B) no fee at all may be charged where there is no dollar amount associated with the violation, which the regulation enumerates as a declined transaction, account inactivity, and closure or termination; and under (b)(2)(ii) only one such fee may be imposed for a single event or transaction. The credit card page sets out the full analysis, and the number that applies to you is the one in your cardholder agreement read against that standard.
Curing it, without asserting what creditors do as a class. A furnisher's obligation under 15 USC 1681s-2(a)(1)(A) is not to furnish information it "knows or has reasonable cause to believe" is inaccurate. So an accurate late mark is not something the dispute process is designed to remove, and a request that a creditor delete a correct mark as a courtesy is exactly that, a request, with no legal entitlement behind it and no way to predict the answer. Where the mark is wrong, the dispute machinery is the route, and that belongs to the credit dispute page.
