Chargeback Time Limits in 2026: Cardholder Filing and Merchant Response Deadlines Explained
Cardholders on major networks like Visa, Mastercard, American Express, and Discover have up to 120 days to file chargeback disputes. This period runs from the transaction date, expected delivery, or problem discovery. Merchants generally get 20-45 days to respond, depending on the network and dispute phase. These timelines remain steady in sources from 2025 and 2026. They let consumers challenge problems like non-delivery or billing errors without rushing, while merchants have a tight window to submit evidence and avoid automatic losses. Cardholders who file early often secure refunds more easily. Merchants that respond on time reverse many disputes. Knowing these deadlines helps both sides avoid missed chances.
Cardholder Chargeback Filing Windows Across Major Networks
Major card networks provide a standard 120-day window for cardholders to start chargeback disputes. This covers typical issues such as fraud, defective products, duplicates, and merchant errors. Visa sets 120 days for most reason codes, including fraud and processing errors. Mastercard provides around 120 days, with some disputes having shorter limits depending on the issue. American Express offers 120 days, adjusted by reason code--for example, from expected delivery in non-delivery cases. Discover follows the 120-day standard (chargebackhelp.com (2025); chargebacks911.com (2026)).
In the US, cardholders also have a legal right to dispute within 60 days, which acts as a baseline next to network rules. Networks typically extend past this minimum.
| Network | Filing Window | Key Notes |
|---|---|---|

| Mastercard | ~120 days | Varies slightly by issue; medium confidence paycompass.com (2025) |
| American Express | 120 days | Starts from transaction, delivery, or discovery; medium confidence chargebacks911.com (2026) |

How Filing Deadlines Are Calculated (Transaction Date vs. Other Triggers)
The 120-day clock for chargeback filing doesn't always begin on the transaction date. Networks adjust it based on the dispute type and reason code. For billing errors or duplicates, it starts from the transaction settlement date. Non-delivery claims typically begin from the expected delivery date. Defective products trigger the period from the date of discovery.
These adjustments promote fairness, giving cardholders facing shipping delays or service issues the full window from the right starting point. Visa, Mastercard, American Express, and Discover each outline these rules by reason code.
Merchant Response Time Limits: 20-45 Days to Fight Chargebacks
Merchants have shorter deadlines to respond to chargebacks, usually 20-45 days from notification. Visa, American Express, and Discover often allow 20 days for the first response. Mastercard and certain Visa phases stretch to 30 or 45 days, which includes time to submit documents. After a merchant representment, issuers get 45 days to rule on pre-arbitration or arbitration chargebacks. Issuers can start pre-arbitration within 20 days of representment.
Merchants lose automatically if they miss these deadlines. Timelines vary by network and phase to balance quick resolution with thorough evidence review. The 20-45 day range accounts for those differences, with 20 days standard for initial responses on Visa, Amex, and Discover (chargebackhelp.com (2025); chargebacks911.com (2026)).
Cardholder vs. Merchant Timelines: Who Has More Time and Why It Matters
Cardholders enjoy up to 120 days to file, compared to merchants' 20-45 days to respond. This setup prioritizes consumer protection but requires merchants to monitor alerts and act fast.
| Timeline | Time Limit | Networks/Phases | Implications |
|---|---|---|---|
| Cardholder Filing | 120 days | Visa, Mastercard (~120), Amex, Discover | Allows time for issue discovery; file early to avoid expiration |
| Merchant Response | 20-45 days | Visa/Amex/Discover (often 20 days); Mastercard/Visa phases up to 45 | Quick evidence submission needed; miss it for auto-loss |
| Issuer Pre-Arbitration | 20 days | Post-representment across networks | Limits merchant appeal window |
| Post-Representment | 45 days | Issuer decision on arbitration | Final chance before resolution |
For consumers:
- Use the 120-day window across networks, but note the US 60-day legal right as a safer prompt threshold.
- Track from transaction date, expected delivery, or discovery to stay within limits.
For merchants:
- Respond in 20-45 days per network rules to avoid automatic chargeback wins for cardholders.
- Prepare evidence ahead for phases like representment, where issuers decide in 45 days.
