MasterCard chargeback time limits set how long a cardholder's issuing bank has to file a dispute—most range from 45 to 120 days from the transaction or notification date, depending on the reason code. Fraud and authorization codes (like 4837, 4870) generally allow up to 120 days, while data-request codes (4802) can be as short as 30 days. As a merchant, once a chargeback is filed you typically have around 45 days to respond with evidence. Miss the window and you forfeit the funds automatically. Tracking deadlines, organizing documentation, and automating responses with a platform like Chargeflow are the keys to winning.
Key Takeaways
- MasterCard time limits define how long the issuing bank has to file a chargeback—most fall between 45 and 120 days from the transaction or notification date.
- Each reason code carries its own deadline; fraud and cardholder-dispute codes usually allow up to 120 days, while data-request codes can be as short as 30 days.
- Once a chargeback is filed, merchants typically have about 45 days to submit a response with evidence.
- Missing a deadline—on either side—means an automatic loss, so accurate date tracking is essential.
- Organized documentation and automated dispute responses (like Chargeflow) are the most reliable way to meet deadlines and recover funds.
As a merchant accepting MasterCard payments, chargebacks are part of the reality of doing business. A chargeback occurs when a cardholder disputes a transaction and funds are reversed from your account. MasterCard groups these disputes into reason codes—covering fraud, authorization and processing errors, and customer disputes—and each code has its own time limit for filing and for submitting supporting documentation. Knowing those windows is the difference between recovering revenue and losing it by default.
What are MasterCard chargeback time limits?
A MasterCard chargeback time limit is the maximum period within which a dispute under a given reason code must be initiated by the cardholder's issuing bank. These deadlines exist to ensure prompt resolution and prevent indefinite disputes. If the issuer misses the window, the chargeback generally can't proceed; if you as the merchant miss your response window, you lose the ability to dispute the chargeback or recover funds. Staying under Mastercard's chargeback thresholds also keeps you clear of separate merchant audit checks like the Mastercard GMAP program.
What factors affect the time limit?
Three things determine the deadline that applies to any given dispute. First, the type of reason code: fraud-related codes often carry shorter windows because of the urgency, while customer-dispute codes allow longer periods. Second, the start date: the clock typically runs from the transaction or notification date, so accurate tracking is critical. Third, documentation submission deadlines: even with a valid case, late or incomplete documentation weakens or forfeits your response.

How can merchants meet MasterCard chargeback deadlines?
Meeting deadlines comes down to process. Monitor chargeback notifications daily so nothing slips past its window, and assign a dedicated owner who knows MasterCard's rules. Keep documentation organized—transaction records, receipts, shipping and delivery confirmation, and customer communications—in a centralized system so evidence is ready to submit on demand. And collaborate proactively with your acquirer, submitting complete, accurate responses within the required time frame. The merchant response window after a chargeback is filed is typically around 45 days, so speed matters as much as evidence quality.
