Mastercard Chargeback Time Limits at Each Stage
Mastercard sets a clock on each step of a dispute, from the first chargeback to the final appeal. Here is who the clock applies to, when it starts, and what a missed deadline costs.
A Mastercard dispute is a chain of steps, and each step has its own clock. The issuer files the chargeback. The acquirer answers it. The issuer may escalate, then arbitrate, then appeal. Miss a clock and the case can die on a technicality. This page walks through the Mastercard chargeback time limit at each stage. The steps run in order. Mastercard's own chargeback guide is the source. For the wider picture across card brands, start with the site's page on the chargeback credit card time limit.
What the Mastercard chargeback time limit means, and whose clock it is
Each deadline in a Mastercard dispute belongs to one party. The issuer's bank has a deadline to file. The merchant's bank has a deadline to answer. The issuer has another to escalate. The clocks run in calendar days, and they start from a fixed point in the transaction, not from the day someone notices a problem.
The numbers below come from Mastercard's rules. If you are on the merchant side of this, the Mastercard chargeback guide covers the merchant view of the same process.
When the clock starts: day zero
Every clock needs a starting day. Mastercard's guide says the Settlement Date of the disputed transaction is counted as day zero. For Single Message System transactions, the guide says the Settlement Date is counted as day zero. That date sits in DE 15 of the message.
For Dual Message System transactions, the guide says the Central Site Business Date is counted as day zero. That date sits in PDS 0158, subfield 5, of the GCMS message.
The short version: the clock does not start when the cardholder complains. It starts on a date recorded inside the payment message itself.
The issuer's chargeback deadline
How long the issuer has depends on why it is charging back. Mastercard ties the issuer's time limit for a chargeback to the chargeback reason code. The reason code is set by what went wrong, so the deadline moves with the problem.
One example shows the pattern. Mastercard generally gives the issuer 90 calendar days from the transaction to charge back when required authorization was not obtained. Other reason codes carry their own windows. A merchant answering a chargeback should read the code on the case first. Do not assume anything about timing.
A chargeback may be for the total transaction amount or a lesser amount. The guide says the total amount being charged back must not exceed the total transaction amount.
The acquirer's second presentment window
Once the issuer files, the clock moves to the merchant's side. Mastercard generally gives the acquirer 45 calendar days from the chargeback to send a second presentment. That is the merchant's bank pushing the money back the other way with its evidence.
Pre-arbitration deadlines and the waiting period
When a second presentment arrives, the issuer can escalate to pre-arbitration. Two clocks govern that move.
First, the documents. Mastercard makes the issuer wait at least eight calendar days for promised second presentment documents before filing pre-arbitration. The guide says a pre-arbitration case is invalid if the issuer files it too soon. The wait for documents must run out first. There is one way around the wait. The issuer may file the pre-arbitration case right away when the second presentment supporting documentation indicator code is 0.
Second, the filing itself. Mastercard generally gives the issuer 30 calendar days from the second presentment to file a pre-arbitration case. Once a case is filed, Mastercard accepts a pre-arbitration case for the acquirer on its own after 30 calendar days from the submit date.
Not every transaction gets this step. The guide says pre-arbitration is prohibited for ATM transactions. It also says pre-arbitration is optional for most transactions. An issuer may skip it and file an arbitration case. Mastercard's guide strongly recommends skipping the optional pre-arbitration step and filing an arbitration case.
Arbitration filing deadlines and the appeal window
If pre-arbitration is rejected, the issuer can go to arbitration. Mastercard generally gives the issuer 15 calendar days after a pre-arbitration rejection to file an arbitration case.
ATM and Maestro disputes run on a different track. Mastercard gives the issuer 45 calendar days from the second presentment to file arbitration in ATM and Maestro disputes.
The case is not locked once filed. The guide says the issuer may withdraw an arbitration case at any time. The cutoff is when the acquirer accepts it or Mastercard rules on it. An acquirer may accept an arbitration case before Mastercard rules on it. By accepting, it also takes on the cost of the disputed transaction.
After a ruling, one more clock runs. A party must get its appeal to Mastercard within 45 calendar days of the Mastercard ruling. And the appeal has hard edges. The guide says new or updated information will not be accepted in any appeal.
What happens when a deadline is missed
A chargeback filed late is not a chargeback that stands. Mastercard's guide says a chargeback is invalid if it was processed past the time frame specified for the chargeback. The guide names reason code 2702, Past Chargeback Time Limit, for Dual Message System transactions. It is used when a chargeback was processed past its time limit on those transactions.
The code marks a chargeback that came in past its time limit.
There is a trap on the other side too. Mastercard holds the issuer liable if it skipped a required pre-arbitration case or filed arbitration too late.
One more wrinkle. The guide says GCMS will not reject a message solely because it was sent after the time frame for the cycle. A late message can slip through the system. That does not make it valid.
Late documentation: what counts and what does not
Documents have their own clocks, and they are strict. Mastercard's guide says chargeback supporting documentation received after the allowed time frame will not be considered. The guide also says late documents do not count. This holds even if they arrive on the same day as the arbitration filing.
For pre-arbitration and arbitration, the guide says the documents must be sent with the case. They cannot follow later. Arbitration is stricter. Mastercard will not consider documents in an arbitration filing if they were needed earlier but were not sent then.
The lesson for anyone building a case: the documents travel with the filing, or they do not travel at all.
On the receiving end, the guide says the issuer must accept supporting documents. This holds as long as the issuer has not yet filed a pre-arbitration case.
Special cases: ATM, Maestro, hardship and translation
A few situations bend the rules. ATM and Maestro disputes carry the 45-day arbitration window noted above. Pre-arbitration is barred for ATM transactions.
Mastercard names one narrow case for special treatment. Mastercard's guide says a hardship variance is considered when a natural disaster causes severe operational difficulties.
Translation matters too. The guide says Mastercard will likely rule against the issuer if the required translations are missing. A strong case in the wrong language can lose on its own.
How these deadlines compare with Visa's
Mastercard is not the only brand with clocks on its disputes. Visa's deadlines have their own page on this site. The site's page on the chargeback time limit for Visa lays them out side by side. New to Mastercard disputes? The page on chargebacks under Mastercard covers the basics of the process behind these deadlines.
The pattern to carry away is simple. Each party gets a fixed window at each step. Each window starts on a date recorded in the payment message. And a chargeback processed past its time frame is invalid, while an issuer that files arbitration too late is held liable.
