Chargeback Time Limits by Card Network [2026]: Complete Reference
Every chargeback dispute has a clock attached to it — and missing a deadline means an automatic loss, no exceptions. This reference covers cardholder filing windows and merchant response deadlines for Visa, Mastercard, Amex, and Discover, with the specific rules that catch merchants off-guard.

Why chargeback time limits matter
Every chargeback dispute is governed by a strict sequence of deadlines. Miss any one of them and the outcome is decided against you — regardless of the strength of your evidence, the legitimacy of the transaction, or whether the cardholder's claim has any merit at all.
For merchants, there are three critical deadlines in a dispute lifecycle:
- 1.Merchant response deadline: The window to submit representment evidence after receiving a chargeback notification. Missing this = automatic loss, full stop.
- 2.Pre-arbitration deadline: If the issuer upholds the chargeback after representment, you can escalate. Miss this window and you permanently lose the right to escalate.
- 3.Arbitration deadline: Final escalation to the card network. The losing party pays a fee ($250–$500). Missing this closes all avenues.
Time limits also vary by card network — and within networks, by dispute category. A Mastercard merchant has 45 days to respond; an Amex merchant has only 20. A merchant processing across multiple networks who applies the wrong deadline to the wrong dispute will lose cases they could have won. Tracking these correctly is non-negotiable for high-volume merchants.
Even winning the initial representment does not protect you if you later miss the pre-arbitration deadline. Issuers can reject your representment and re-initiate the chargeback — at which point you have a new (and shorter) window to act. Staying on top of every stage of the dispute cycle is what separates merchants who consistently win from those who lose on technicalities.
The master reference table
All times are in calendar days from the relevant trigger event. Cardholder deadlines run from the transaction date in most cases; merchant response deadlines run from the chargeback notification date. Pre-arbitration deadlines run from the date the issuer rejects your representment.
| Network | Cardholder deadline | Merchant response | Pre-arbitration |
|---|---|---|---|
| Visa | 120 days | 30 days | 30 days |
| Mastercard | 120 days | 45 days | 45 days |
| Amex | 120 days | 20 days | 20 days |
| Discover | 120 days | 30 days | 30 days |
All deadlines are calendar days, not business days. Network rules govern; your acquirer or processor may impose earlier internal deadlines — always confirm with them. Data reflects network operating regulations current as of June 2026.
Cardholder filing deadlines
All four major card networks use 120 days as the standard cardholder filing window — but the starting point of that clock is where the important differences lie, and where disputes that look late can still be valid.
When does the 120-day clock start?
- →Transaction date: The most common starting point — used for most fraud and authorization disputes across all networks.
- →Expected delivery date: For goods-not-received disputes on Visa and Mastercard, the 120 days runs from the date the item was supposed to arrive, not when the order was placed. This can significantly extend the effective window.
- →Statement closing date (Amex): Amex measures the 120 days from the monthly statement closing date on which the disputed transaction appeared — which can be up to 30 days after the transaction itself, giving cardholders effectively up to 150 days from the purchase date.
- →Date of last transaction (recurring billing): For subscription and recurring billing disputes on Visa and Mastercard, the 120 days typically runs from the most recently disputed charge — not the original subscription start date. A customer who cancels after 18 months and disputes the final three months of charges can still file a valid chargeback.
Important: Card network rules are more generous to consumers than US federal law. The Fair Credit Billing Act (FCBA) gives cardholders only 60 days from the statement date to dispute a billing error. But card network rules — which grant 120 days — take precedence in practice. Issuing banks follow network rules, not just the federal floor.
This gap matters for merchants: you may assume a transaction is safe after 60 days because you've heard "the dispute window has closed." Under network rules, you still have up to another 60 days of exposure. For goods-not-received disputes where delivery was expected weeks after the order, you may be exposed for longer still.
Merchant response deadlines by network
The merchant response window opens when your acquiring bank notifies you of the chargeback — not when the cardholder filed it, and not when the issuing bank initiated it. This notification typically arrives 3–7 business days after the dispute is initiated, which means a portion of your window is already consumed before you even know the dispute exists.
Visa gives merchants 30 calendar days from the chargeback notification date. With gathering evidence and writing your rebuttal, 30 days sounds comfortable — but if you batch-review disputes weekly, you can lose more than a third of your window before you start. For Visa, set a reminder the day you receive each notification.
Mastercard's 45-day window is the most generous among the major networks. The clock runs from the Central Site Business Date (CSBD) stamped on the chargeback notification. Despite the longer window, do not treat Mastercard disputes as low-urgency — the evidence requirements are thorough and good responses take time to compile.
Amex's 20-day window is the shortest of any major network and consistently catches merchants off-guard. Unlike Visa and Mastercard disputes (which route through the issuing bank), Amex acts as both issuer and network for most of its cards — which is why their process moves faster. Treat every Amex notification as urgent.
Discover's dispute process closely mirrors Visa, with a 30-day merchant response window. Discover also acts as its own processor for most cards, which means notifications can come directly from Discover rather than through an acquirer intermediary.
Example: chargeback received June 1
| Network | Received | Response due | Window |
|---|---|---|---|
| Visa | June 1 | July 1 (30 days) | 30 calendar days |
| Mastercard | June 1 | July 16 (45 days) | 45 calendar days |
| Amex | June 1 | June 21 (20 days) | 20 calendar days — act fast |
| Discover | June 1 | July 1 (30 days) | 30 calendar days |
Warning: These are the network deadlines. Your processor or acquirer may impose internal deadlines that are several days earlier — particularly if they need time to review and forward your submission to the network. Always check your processor's documentation for their internal cutoff.
Pre-arbitration and arbitration deadlines
Submitting a representment (dispute response) is not the end of the process. If the issuing bank reviews your evidence and upholds the original chargeback, they will reject your representment and issue a pre-arbitration notice. This opens a new, shorter window during which you can escalate to the card network for a binding decision.
Pre-arbitration deadlines
- →Visa: 30 days from the date the issuer rejects your representment
- →Mastercard: 45 days from the issuer's second presentment rejection
- →Amex: 20 days consistent with their overall compressed timelines
- →Discover: 30 days from the issuer's rejection of your response
If you escalate to pre-arbitration and the issuer still upholds the chargeback, the final step is arbitration — where the card network itself makes a binding decision. Arbitration is rarely used in practice because:
- →The losing party pays an arbitration fee of $250–$500 (depending on network and dispute amount)
- →Network decisions at arbitration are final and binding — there is no further appeal
- →Arbitration outcomes tend to follow strict rule interpretation, which may not favour the merchant even with compelling evidence
- →Most experienced dispute managers resolve at the representment or pre-arbitration stage
Missing the pre-arbitration deadline is particularly costly because it comes after you have already invested time gathering evidence and submitting a response. Even if your representment was strong, a missed pre-arb deadline means the chargeback stands permanently. Tracking pre-arb deadlines separately from initial response deadlines is essential for merchants with any dispute volume above a handful per month.
Exceptions and special categories
The standard 120-day cardholder window and the network-standard merchant response windows are starting points, not universal rules. Several categories operate under different time constraints:
Visa fraud disputes (reason code 10.4)
Visa's 10.4 reason code (Card Absent Environment fraud) has a compressed cardholder filing window of 75 days from the transaction date — shorter than the standard 120 days. This affects a large volume of disputes, since 10.4 is among the most commonly filed Visa reason codes. Merchants dealing with high online fraud volumes should be aware that these disputes arrive faster.
Recurring billing and subscription disputes
For recurring transactions, the 120-day window typically runs from the date of the most recent disputed charge — not the original subscription start. A subscriber who was billed monthly for 18 months before cancelling can dispute the final several billing cycles. Each billing cycle effectively resets the exposure window for that transaction.
Delayed delivery disputes
For goods-not-received disputes where a delivery date was stated or reasonably implied, the filing window runs from the expected delivery date rather than the purchase date. For merchants selling custom-made goods, pre-orders, or items with long lead times, this means chargeback exposure extends well beyond the payment date.
ATM and PIN-debit transactions
ATM cash withdrawal disputes and PIN-debit transactions are governed by Regulation E (Electronic Fund Transfer Act) rather than card network rules. The cardholder has 60 days from the statement date to report an unauthorized transaction, and two business days to report if they want liability protection capped at $50. These rules differ significantly from credit card network dispute rules.
Non-receipt of cash from ATM
Disputes where a cardholder did not receive cash from an ATM dispense are treated as errors rather than chargebacks in the traditional sense. Banks investigate these internally and the timelines are governed by Regulation E error resolution requirements (typically 10 business days for initial provisional credit).
Tips for never missing a chargeback deadline
Missing a deadline is one of the most avoidable losses in chargeback management. Unlike losing on the merits — where the evidence wasn't strong enough — a missed deadline means an automatic loss on a case you might have won. Here is a practical system for staying ahead of every deadline:
Set a calendar alert the day you receive each notification
Do this before you do anything else with the dispute. Calculate the deadline (notification date + network window) and put it in your calendar with a reminder 5 days prior. This creates a hard stop even if the dispute sits in a queue for days.
Work backwards from the deadline
Allocate your available days deliberately: 2–3 days for evidence gathering, 1–2 days for writing the rebuttal, 1 day for internal review, 1 day buffer for submission. With a 20-day Amex window, this leaves almost no slack. With a 30-day Visa window, you have a bit more room — but not as much as it seems.
Treat Amex deadlines as 15 days
Amex's 20-day window is the tightest of any major network. Build in a 5-day personal buffer and treat every Amex chargeback as requiring immediate action. If your team processes disputes in batches, Amex cases need to be pulled out and handled on their own track.
Never batch-process disputes across networks
If you review and respond to all chargebacks on the same day each week, you will routinely lose days of your window to queue time. Handle each dispute individually, with its own deadline tracked, rather than treating all disputes as interchangeable.
Use dispute management software that tracks deadlines automatically
Manual spreadsheet tracking works at low volumes but fails as dispute counts grow. Tools like ChargeMate automatically track deadlines per dispute, send reminders, and flag cases approaching their response window — eliminating missed deadlines from operational oversight.
Monitor your processor inbox daily
Chargeback notifications frequently arrive in processor email notifications or portal alerts. If these go to a shared inbox, a spam folder, or an email that is not monitored every business day, you may not see a notification until several days after it arrived — when a meaningful portion of your response window is already gone.
