Missing a chargeback deadline is one of the most expensive mistakes a merchant can make. It doesn't matter how strong your evidence is or how clear-cut the case—if you respond one day late, you automatically lose the dispute with no appeal. Each card network sets its own time limits, and they differ significantly. This guide covers every deadline across all four major networks so you never miss a response window.

| Deadline | Visa | Mastercard | Amex | Discover |
|---|---|---|---|---|
| Cardholder filing window | 120 days from transaction or expected delivery | 120 days from transaction or expected delivery | 120 days from transaction | 120 days from transaction |
| Merchant response (representment) | 30 calendar days | 45 calendar days | 20 calendar days | 30 calendar days |
| Pre-arbitration / second chargeback | 30 calendar days | 45 calendar days | N/A (single review) | 30 calendar days |
| Arbitration filing | 10 business days | 45 calendar days | N/A | 10 business days |
These are network deadlines. Your payment processor may impose shorter deadlines to give themselves processing time. Always check with your processor for their specific cutoff dates—they may subtract 5-10 days from the network deadline.
Visa Time Limits
Cardholder Filing: 120 Days
Cardholders can file a Visa dispute within 120 calendar days of the transaction date or the expected delivery date (whichever is later). For recurring transactions, the 120-day window starts from the date of each individual charge, not the original subscription date.
Merchant Response: 30 Calendar Days
Once you receive a chargeback notification, you have 30 calendar days to submit your representment response. This clock starts from the date the chargeback is processed, not the date you receive notification. If your processor delays notification by a week, you've already lost a week of your response window.
Pre-Arbitration: 30 Calendar Days
If the issuer rejects your representment and files a pre-arbitration case, you have another 30 calendar days to respond. At this stage, you can accept the chargeback, provide additional evidence, or proceed to arbitration.
Arbitration: 10 Business Days
If you choose to escalate to Visa arbitration, you must file within 10 business days of the pre-arbitration decision. Arbitration involves a $500 filing fee (charged to the losing party) and a binding decision from Visa.
Mastercard Time Limits
Cardholder Filing: 120 Days
Mastercard allows 120 calendar days from the transaction date or expected delivery date. For certain dispute categories (like processing errors), the clock may start from the date the cardholder discovered the error.
Merchant Response: 45 Calendar Days
Mastercard gives merchants the most generous response window: 45 calendar days from the chargeback date. This extra time can be valuable for gathering evidence, especially for complex disputes involving third parties or international shipping.
Second Presentment / Arbitration: 45 Calendar Days
Mastercard's collaboration process (their equivalent of Visa's pre-arbitration) also allows 45 calendar days. If the dispute proceeds to arbitration, the filing window is 45 calendar days with a filing fee of $300-$500 depending on the dispute amount.
Mastercard calculates chargeback ratios differently from Visa. While Visa uses the month the chargeback was filed, Mastercard uses the month the original transaction was processed. This means a chargeback filed in March for a January transaction counts against your January ratio. This distinction matters for chargeback ratio calculations.
American Express Time Limits
Cardholder Filing: 120 Days
Amex allows 120 days from the transaction date. Because Amex operates as both the network and the issuer for most transactions, their process differs from Visa and Mastercard.
Merchant Response: 20 Calendar Days
Amex gives merchants the shortest response window: just 20 calendar days. This tight deadline catches many merchants off guard, especially those accustomed to Visa's 30-day or Mastercard's 45-day windows. With Amex, you need to have your evidence gathering process streamlined and ready to go the moment a dispute notification arrives.
No Pre-Arbitration Stage
Amex does not have a formal pre-arbitration or second chargeback stage like Visa and Mastercard. Their dispute process is a single-round review: you submit your response, Amex reviews it, and they make a final decision. This makes your initial response even more critical—you typically get one shot.
Amex's 20-day window is the tightest in the industry. If your processor takes 3-5 days to forward the notification, you may have as few as 15 days to prepare and submit your response. Set up real-time dispute notifications with your processor if you accept Amex.
Discover Time Limits
Cardholder Filing: 120 Days
Discover allows 120 days from the transaction date, consistent with the other networks.
Merchant Response: 30 Calendar Days
Discover gives merchants 30 calendar days to respond, matching Visa's timeline. Discover operates its own dispute resolution process that is similar to but independent from Visa's.
Arbitration: 10 Business Days
If the dispute is not resolved at the first review stage, merchants have 10 business days to file for arbitration. Discover's arbitration process involves a compliance review and binding decision.
Processor vs. Network Deadlines
There's an important distinction between network deadlines (listed above) and the deadlines your processor gives you. Most processors impose earlier deadlines to give themselves time to process and forward your response to the network.
| Scenario | Network Deadline | Typical Processor Deadline | Your Effective Window |
|---|---|---|---|
| Visa representment | 30 calendar days | 20-25 calendar days | 15-20 days (after notification delay) |
| MC representment | 45 calendar days | 30-40 calendar days | 25-35 days |
| Amex representment | 20 calendar days | 15-17 calendar days | 10-14 days |
| Discover representment | 30 calendar days | 20-25 calendar days | 15-20 days |
Always use your processor's deadline, not the network's deadline. If your processor says you have 20 days, treat that as your hard deadline even though the network allows 30.
How to Track Deadlines
With potentially dozens of active disputes across multiple networks, deadline tracking is a critical operational process.
- Set up real-time notifications: Configure your processor's portal or API to send immediate email/SMS alerts when a new chargeback is filed.
- Calendar the response deadline immediately: The moment you receive a dispute notification, calculate the deadline and add it to your calendar with a reminder 7 days before and 3 days before.
- Track by network: Maintain a dispute log that records the network, case number, filing date, your processor's deadline, and the current status.
- Build in buffer time: Aim to submit your response at least 3-5 days before the deadline. Technical issues, processor delays, or evidence-gathering complications can consume your remaining time.
- Assign ownership: Every dispute should have a clear owner responsible for meeting the deadline. Unassigned disputes are missed disputes.
Consequences of Missing Deadlines
There are no extensions, exceptions, or appeals for missed chargeback deadlines. The consequences are absolute:
- Automatic loss: You forfeit your right to represent the transaction. The chargeback stands permanently.
- No appeal: You cannot appeal a deadline miss. The network and issuer will not review late submissions.
- Ratio impact: The chargeback counts against your chargeback ratio with no possibility of reversal.
- Revenue loss: You lose the transaction amount, the chargeback fee, and the merchandise or service already delivered.
- Precedent effect: Missed deadlines for recurring customers may embolden future disputes, as the cardholder learns they can file without opposition.

Do weekends and holidays count toward chargeback deadlines?
For most deadlines, yes. Visa, Mastercard, and Discover use calendar days (including weekends and holidays) for representment deadlines. The exception is arbitration filing windows, which some networks measure in business days. Always count calendar days for representment and check with your processor for arbitration-specific rules.
Can I request an extension on a chargeback deadline?
No. Card network deadlines are non-negotiable and non-extendable. Neither your processor nor the network will grant extensions for any reason, including holidays, staffing issues, or evidence delays. The only way to manage deadlines is to respond within them.
When does the clock actually start?
The network clock starts when the chargeback is processed (the date the issuer formally files it with the network). However, there's often a delay of 2-7 days between processing and when you receive notification from your processor. Your effective response time is the network deadline minus this notification delay. This is why processor-imposed deadlines are shorter than network deadlines.
What if my processor notified me late and I missed the deadline?
Unfortunately, the merchant bears the risk of processor notification delays. If your processor's notification system was significantly delayed, you may have a contractual claim against your processor, but the chargeback itself cannot be reversed. This is why real-time dispute notifications and proactive monitoring are essential. Consider switching processors if notification delays are a recurring problem.
