Chargeback Time Limit: Everything You Should Know as a Merchant

Quick answer: A chargeback time limit is the fixed window each party has to act during a dispute. Cardholders generally have up to 120 days from the transaction or delivery date to file a chargeback (some fraud reason codes are shorter, and a few Visa codes stretch to 540 days). Merchants have much less time to respond—typically 30 days for Visa and Discover, 45 days for Mastercard, and 20 days for American Express, per dispute phase. Miss your window and you forfeit the dispute automatically.

The chargeback time limit is a fixed period in which all parties involved in the dispute can respond at any phase of a chargeback process. Cardholders, banks, and vendors must adhere to the card network's stipulated dispute timeline to initiate a chargeback or contest a claim.

As a merchant, you need to understand the time limits of the card brands your store accepts. This knowledge gives you a clear runway to exercise your dispute-mediation rights and contest any meritless chargeback so you don't lose cases by default.

Chargeback Time Limits by Card Network (2026)

Here's the at-a-glance comparison of cardholder filing deadlines and merchant response windows across the major networks:

The two time limits that matter most are:

1. The time limit for cardholders: 60 to 120 calendar days to dispute a charge (longer for select reason codes).
2. The time limit for merchants: the period you have to respond to a claim at each phase.

How Long Do Merchants Have to Respond to a Chargeback?

By and large, merchants have 30 days to respond to each chargeback phase when a Visa or Discover card is involved. Mastercard gives merchants 45 days for each stage of the dispute, while American Express sets a 20-day response limit for any phase of the case lifecycle.

It's essential to note that chargeback time limits for acquirers differ from those for merchants. Depending on the issuer, acquirers use 20 or 45 days to complete administrative tasks, which can eat up huge chunks of time at any stage and leave you with a tiny window to:

• Gather compelling evidence
• Craft a bullet-proof response letter
• Submit your representment case

What Goes Into Deciding a Chargeback Time Limit?

Several factors determine chargeback time limits. First is the chargeback reason code. On the cardholder's side, most reason codes allow a dispute 90–120 days from the transaction date. Chargebacks caused by internal merchant errors have a shorter time frame, since the issuer or processor can catch them before they reach the consumer.

Aside from issuers, your payment service provider also controls how much time you have. If your processor is PayPal, customers have 180 days to file a claim—twice what the major card brands give—yet you may have only a short window to respond. Compare how PayPal disputes work to plan your response strategy.

While card chargeback time limits begin on “Day One” of each dispute phase, you may get the chargeback notice much later—sometimes 2–3 days before the response deadline due to administrative delays from your acquirer. The Day One qualifier resets at every chargeback phase, so even though limits are predefined, they shift with your progress through the dispute stages. Arbitration typically gives the merchant 10 days to refute claims.

Insight Into Card Network Time Limits

Card schemes have the most significant control over chargeback time limits. There are no uniform rules or wording, but the underlying principle is the same: to expedite the process and ensure a clear consensus. Below we review each network in detail.

Visa Chargeback Time Limits

Visa gives cardholders up to 120 days from the original transaction or delivery date to file a chargeback. Unauthorized/fraudulent transaction disputes may attract exceptions where Visa allows filing within 75 days. For acquirers and merchants, Visa demands a response within 30 days of Day One for each dispute phase, with a 10-day exception for arbitration or pre-arbitration.

Mastercard Chargeback Time Limits

Cardholders in the Mastercard network have 120 days from the Central Site Business Date (CSBD) to file a chargeback—the day the merchant processed the transaction or delivered the order. Mastercard gives acquirers and merchants 45 days as the standard response limit, with a key exception: when they issue a request for more information, the merchant must respond within 18 days.

Discover Chargeback Time Limits

Discover acts as both a bank and a card network. Like Visa and Mastercard, it gives cardholders a maximum of 120 days after a transaction to file a dispute (shorter for some reason codes). On the merchant side, Discover sets the initial response limit at 20 days. If any party wishes to appeal a representment outcome, they must do so within 30 days, and merchants have 15 days to request arbitration.

Amex Chargeback Time Limits

Amex cardholders must dispute a charge within 120 days of the original transaction, and cardmembers can file only two disputes on one order. For acquirers and merchants, Amex requires a response within 20 days by either accepting the dispute or proving the chargeback is meritless.

What Happens If You Miss the Chargeback Deadline?

If a merchant misses the response deadline, the chargeback is automatically resolved in the cardholder's favor—you lose the disputed amount, pay the chargeback fee, and the loss counts toward your dispute ratio. Repeatedly missing deadlines pushes you toward network monitoring programs (and their penalties), so a reliable, fast response workflow is essential. Much of this volume is friendly fraud, which is winnable—but only if you respond in time with the right evidence.

2026 Rule Updates to Watch

Card networks continually refine dispute rules. In 2025 Visa consolidated its older dispute- and fraud-monitoring programs into the Visa Acquirer Monitoring Program (VAMP), changing how dispute and fraud ratios are measured. Visa's Compelling Evidence 3.0 also reshaped what qualifies as proof for certain fraud (reason code 10.4) disputes, rewarding merchants who can show a prior undisputed transaction history with the same customer. Staying current on these rules directly affects whether your evidence is accepted within the response window.

Beat the Clock and Win More Disputes

Chargeback time limits speed up the dispute process but pile pressure on merchants. If you manage chargebacks manually, it's hard to respond within the allotted time—and rushing means you omit evidence that could win the case or fall foul of ever-changing rules.

With Chargeflow's automated chargeback solution, you stay on top of every dispute. You can gather compelling evidence, customize responses to optimize win rates, and submit on autopilot—removing redundancies and scaling as your business grows. Pair it with real-time chargeback prevention alerts to resolve issues before they ever become chargebacks. And because Chargeflow uses success-based pricing, you only pay when you win.
