Credit Card Dispute Timelines by Issuer: Chase, Amex, Capital One & More

Under US law, a credit card issuer has at most 90 days to resolve a billing-error dispute on a consumer card, and most big issuers tell cardholders to expect anything up to that limit. That issuer clock runs alongside a much shorter one on the merchant’s side: the processor usually gives the merchant 7 to 21 days to respond. This guide covers what each major issuer publicly says, the federal rules behind those numbers, how the UK differs, and what it all means if you’re the merchant on the other end.

Everything below reflects issuers’ public help pages and the federal regulations as published in November 2026. Issuers can and do resolve cases faster than the limits; they can’t legally take longer on a consumer credit card billing error.

The short answer

The US legal backbone

Credit cards: Fair Credit Billing Act and Regulation Z

The Fair Credit Billing Act, implemented by Regulation Z (12 CFR 1026.13), sets the clock for billing errors on consumer credit cards:

• 60 days for the cardholder. The written notice must reach the issuer no later than 60 days after the issuer sent the first statement showing the error, at the address the issuer designates. Online submission counts as written only if the issuer’s billing-rights statement says it accepts electronic notices.
• 30 days to acknowledge. The issuer must send written acknowledgment within 30 days of receiving the notice, unless it has already resolved the error.
• Two billing cycles, 90 days maximum, to resolve. The issuer must resolve the error within two complete billing cycles, and in no event later than 90 days after receiving the notice.
• No collection while it investigates. The cardholder doesn’t have to pay the disputed amount, and the issuer can’t try to collect it or report it as delinquent, though it can note that the account is in dispute.

Issuers often accept disputes after the 60-day window anyway, because card network rules give cardholders longer. Capital One, for example, recommends filing within 60 days of the statement date but says it may still be able to help after that.

Debit cards: Regulation E

Debit card disputes fall under Regulation E (12 CFR 1005.11), with a different clock:

• The consumer must notify the bank within 60 days after the statement showing the error.
• The bank must investigate and decide within 10 business days.
• It can take up to 45 days if it provisionally credits the consumer’s account within those 10 business days.
• That extends to 90 days for point-of-sale debit card transactions, transfers not initiated within a state, and transfers in the first 30 days after an account’s first deposit (where the initial window is also 20 business days instead of 10).

Debit timelines matter to merchants because a large share of card-not-present volume is debit, and a provisional credit within 10 business days means the cardholder has their money back long before your case is decided.

Dispute timelines by issuer

Here is what each major US issuer publicly says about dispute timing. Where an issuer doesn’t publish a number, we say so; those disputes still follow the Regulation Z limit.

Three patterns stand out.

American Express is fastest because it controls more of the chain. Amex is usually both the card network and the issuer, and for many merchants the acquirer too, so fewer handoffs are involved. Amex’s non-US pages give longer windows (its UK guidance says investigations can take up to six to eight weeks).

“Up to 90 days” is the regulatory ceiling, not the typical case. Chase and Capital One quote the legal maximum. Simple cases where the merchant doesn’t respond often close much sooner.

Fraud claims and merchant disputes run on different tracks. A fraud claim (“I didn’t make this purchase”) usually gets a new card and a fast provisional credit. A merchant dispute (“I never received it”, “it wasn’t as described”) depends more on the merchant’s response, so it tends to take longer.

Apple Card’s issuer transition

Apple Card’s support page states that Apple Card is issued by Goldman Sachs Bank USA, Salt Lake City Branch, and formal billing-error notices go to Goldman Sachs in writing. On January 7, 2026, JPMorgan Chase announced it will become the new issuer, with the transition expected to take about 24 months and subject to regulatory approvals. Mastercard remains the network. Until the transition is complete, disputes are handled by Goldman Sachs; either way, the Regulation Z limits apply.

Business credit cards

Regulation Z’s billing-error rules apply to consumer credit. Credit extended primarily for business purposes is generally exempt, so business and corporate card disputes follow the cardholder agreement and card network rules. In practice, many issuers handle them on similar timelines, but there’s no federal 90-day guarantee. Chase’s business disputes page, for instance, says disputes can take up to 90 days and arbitration cases longer.

UK credit card disputes

UK cardholders have two separate routes, and they run on different rules.

Section 75 of the Consumer Credit Act 1974 makes the credit card provider jointly responsible with the merchant for breach of contract or misrepresentation, where the cash price of the item is more than £100 and not more than £30,000. It covers credit cards, point-of-sale loans and certain catalogue accounts, but not debit cards or charge cards. Section 75 is a legal right, has no 120-day cap, and the Act gives the card provider a right to be indemnified by the supplier. There is no fixed timescale for a Section 75 claim to be decided.

Chargeback is a card scheme process, not a legal right. It covers debit and credit cards, has no minimum value, and the cardholder usually has around 120 days to raise it, per the Financial Ombudsman Service, longer or shorter depending on circumstances. A bank doesn’t have to raise a chargeback.

If the cardholder isn’t satisfied, they make a formal complaint to the card provider. If the provider doesn’t send a final response within eight weeks (shorter limits apply to some payment-services complaints), or the cardholder disagrees with it, they can refer the complaint to the Financial Ombudsman Service, generally within six months of the final response.

For UK merchants, a chargeback looks the same as anywhere else: it arrives through your acquirer under Visa or Mastercard rules, and your representment deadline is set by your acquirer or processor. A Section 75 claim may not reach you as a chargeback at all, which is why keeping clean records of delivery and terms matters even outside the dispute process.

How the issuer’s clock meets the merchant’s clock

From the merchant’s side, the issuer timeline looks like this:

1. Cardholder contacts the issuer. The issuer may try to resolve it, issue a provisional credit, or ask the cardholder to contact you first.
2. The issuer files a chargeback through the network. Your processor debits the funds (usually plus a chargeback fee) and notifies you.
3. You respond within your processor’s deadline, typically 7 to 21 days. Networks allow acquirers somewhat longer, but your processor’s date is the one that counts. See chargeback time limits.
4. The issuer reviews your representment, often 30 to 75 days.
5. The cardholder can push back, which can lead to pre-arbitration and adds weeks or months.

The key interaction: the issuer has to resolve the cardholder’s billing error within its Reg Z window, and your representment is the evidence it weighs. A missed response usually means the case closes for the cardholder without your side ever being read. A timely, complete response is the only way your evidence is part of the decision. The full sequence is mapped in the chargeback dispute lifecycle and how long a chargeback takes.

What this means for merchants

• Your clock is the short one. The issuer may have 90 days; you have days. Build a process that reacts within 24 hours of notification.
• Answer inquiries. Amex and Discover often send an inquiry before a chargeback. Responding can stop the dispute before it starts.
• Don’t count provisional credits as outcomes. A cardholder’s temporary credit isn’t a ruling, and neither is your processor’s debit.
• Expect cash to be tied up for months. Between the debit and the final decision, plan for 30 to 90 days, longer with escalation.

The response window is where automation helps most. DisputeDash detects a dispute as soon as your processor reports it, gathers the reason-code-specific evidence, writes the rebuttal and submits inside the window, so the issuer’s decision is always made with your side in the file.

Bottom line

For US consumer credit cards, issuers must resolve billing-error disputes within two billing cycles and 90 days at most; Chase and Capital One quote up to 90 days, and Amex says most US cases close in under two weeks. Debit disputes follow Regulation E’s 10-business-day and 45 or 90-day rules. UK disputes run through scheme chargebacks or Section 75, with the Financial Ombudsman as the backstop. Whatever the issuer’s clock says, the merchant’s window is 7 to 21 days, and that’s the one that decides whether you have a case at all.
