Chargeback Time Limits in 2026: Deadlines for Merchants

Chargeback time limits run on two separate clocks. The first is how long a cardholder has to dispute a charge. The second is how long you have to answer once the dispute reaches you. The first clock is long, often about 120 days for standard disputes and longer in delayed-delivery cases. The second is short, and the due date on your case notice is the only date that counts.

This guide explains both clocks for Visa and Mastercard, what U.S. consumer law adds, how reason codes change the timing, and how to build a process that never misses a deadline.

TL;DR

• Cardholder clock: card network disputes are commonly described as having a 120-day window, with longer limits for some delayed-delivery cases. Consumer law adds its own 60-day billing-error rule for credit cards.
• Merchant clock: your response deadline is set by your processor and is shorter than the network's own stage windows. Treat the date on the case notice as final.
• Reason codes decide the details: Mastercard ties timing to the reason code and chargeback cycle, so there is no single universal number.
• Monitoring programs matter: a rising dispute ratio can bring network programs, fees and reviews. Rules and thresholds change, so confirm current figures with your acquirer.
• Prevention beats speed: clear descriptors, fast refunds and saved evidence shorten every dispute.

The two clocks of a chargeback

A chargeback starts with the cardholder's bank, the issuer. The issuer files a dispute through the card network. Your acquirer or processor passes it to you. From that point you work against a deadline set by the processor, which is built to fit inside the network's stage windows.

The numbers differ by network, reason code and issuer. Always read the case notice for the real due date.

Cardholder filing windows

What U.S. law says

Federal law sets a floor for credit card billing errors. Under the CFPB's Regulation Z, a written billing-error notice must reach the creditor no later than 60 days after the first statement showing the alleged error was sent. The FTC gives the same guidance for credit and debit card errors: report within 60 days of the first statement containing the charge, in writing, to the address the issuer lists for billing disputes.

The CFPB also tells consumers who want a refund for defective, undelivered or misdescribed goods to contact the seller first and send a billing-error notice within 60 days of the charge appearing on the statement.

There is a longer route for some disputes. The California Attorney General explains that billing errors are generally disputable up to 60 days after the bill date, while certain claims and defenses may be raised up to one year after the bill date when conditions are met. Those conditions include an amount over $50, a qualifying seller location, a good-faith effort to resolve the matter with the seller, and a balance not already paid in full.

What card networks add

Card network rules are separate from consumer law. Issuers dispute through network reason codes, and each code has its own time frame. Many guides describe 120 days as the standard window, counted from the transaction date or, for goods and services not yet received, from the expected delivery date. Some delayed-delivery disputes can run much longer, up to 540 days under Visa's published approach. Check the current Visa rules with your acquirer before relying on any single figure.

Issuers also have their own policies. Capital One, for example, says cardholders should file as soon as an issue is identified, ideally within 60 days of the statement date, and that it may still help after that window. So a customer who contacts a bank at day 90 or day 130 may still get a hearing. Approval is not automatic, but you should expect late disputes to arrive.

Can a cardholder dispute after 120 days?

Sometimes. Reason-code windows differ, delayed delivery can extend them, and some U.S. claims-and-defenses rights reach one year. Ordinary billing-error protections generally do not extend that far. For a merchant, the practical rule is to keep your evidence for well over four months after a sale, and longer for prepaid, subscription or delivery-based sales.

Merchant response windows

You do not respond to the network. You respond to your processor, through the dispute portal or a notice email. Networks give stages of their own, commonly described as about 30 days for each response stage, and the stage that follows a rebuttal has its own short window. Your processor needs time to package and submit your evidence, so its internal deadline is shorter.

That gap is where most late responses come from. A merchant reads a general guide, sees 30 days, and plans accordingly. The processor's notice says seven or ten. The case is lost without a rebuttal.

Three habits prevent it:

1. Read the due date on every notice. Ignore generic numbers.
2. Log the date you received the notice, not the date you opened it.
3. Set a reminder at half the time remaining. That leaves room for missing records.

Our guide to chargeback representment walks through how to build the evidence package once the clock is running.

Mastercard rules for 2026

Mastercard does not state one universal merchant or consumer deadline for U.S. transactions. Its official Chargeback Guide for merchants makes timing depend on the reason code and the chargeback cycle. That means the answer to "how long does the cardholder have?" is "it depends on the dispute type."

A few rules from that guide are worth knowing:

• One chargeback per amount. An issuer is limited to one chargeback for each presented transaction amount within the time frame of the relevant reason code. A chargeback can be full, partial, or multiple partial amounts, as long as the total does not exceed the original clearing amount.
• Rules change. Mastercard states on its rules page for merchants that its rules and standards change over time and that documents on its site may not always be current. Verify the applicable current rules with your acquirer.
• Hardship variances exist. The guide recognizes variances for severe operational difficulties caused by a natural disaster. A variance can remove processing-time edits for specified chargeback cycles, while other reason-code requirements stay in place. See the Mastercard guide copy for the wording.

Visa reason codes and what they mean for timing

Visa groups disputes into categories, and merchants usually meet them as a number on the case notice. The categories are fraud, authorization problems, processing errors and consumer disputes. Visa's current dispute framework organizes these under condition-based categories, and your acquirer's portal translates the code into plain language.

What matters for deadlines:

• Fraud disputes are often filed early, when the cardholder spots an unknown charge on a statement.
• Authorization and processing errors tend to be clear-cut and are usually settled with a refund or a correction.
• Consumer disputes (goods not received, not as described, canceled subscriptions) are the ones that run long, because the clock can start from the expected delivery date, not the purchase date.

If you sell anything that ships later, renews or is delivered in stages, your exposure window is longer than 120 days. That is true for annual SaaS plans, pre-ordered products, catering deposits and healthcare payment plans.

Monitoring programs: why dispute volume has its own deadlines

Card networks track the ratio of disputes to sales. When a merchant crosses a threshold, the network can place it in a monitoring program. Visa runs a program for acquirers and their merchants, and Mastercard runs an excessive chargeback program. Thresholds, fees and review periods change. Reported figures have shifted in recent years, so ask your acquirer for the current numbers instead of relying on an article.

What monitoring means in practice:

• Your processor may ask for a remediation plan with its own deadlines.
• Fees can apply per dispute while you are enrolled.
• Repeated time in a program can lead to reserve requirements or account review.

The point for time limits is simple. Missed deadlines turn into lost disputes, and lost disputes raise your ratio. Responding on time to every case protects the number the networks watch.

A worked timeline

Here is an example of how the two clocks interact. The dates are illustrative, not a promise of how any single issuer will act.

1. Day 0: A customer buys an annual software plan.
2. Day 20: The customer stops using the product and forgets to cancel.
3. Day 75: The renewal reminder is missed. The customer sees the charge and calls the bank.
4. Day 80: The issuer files a dispute. Your processor sends a case notice with a due date.
5. Day 85: You submit the signed terms, login history and the renewal reminder email.
6. Day 120 and beyond: Any later dispute on a new reason code arrives in a fresh window.

In this example the cardholder's clock was still far from running out. Your clock was the short one, and it began the day the notice arrived.

How to never miss a chargeback deadline

1. Send alerts to a shared inbox, not one person's email. A vacation should not cost you a case.
2. Track every case in one sheet with notice date, processor due date and status.
3. Store evidence by transaction: receipts, signed terms, delivery proof, login or usage logs, and customer emails.
4. Keep records at least a year, longer for subscriptions and delayed delivery.
5. Refund early when the claim is valid. A refund before a dispute is filed costs less than a lost dispute.
6. Use clear billing descriptors so customers recognize the charge.
7. Reconcile monthly. Our chargeback accounting guide shows the journal entries and reconciliation steps finance teams need.

Keep consent and entry data clean

Many disputes on recurring charges come down to proof of permission. Documented consent and correct entry modes make a rebuttal faster. Our guide to card-on-file consent covers what to capture at signup.

Watch surcharges and fee notices

If you add a surcharge, the notice and disclosure rules apply, and a missing disclosure can become a dispute. See card brand surcharge rules and U.S. credit card surcharge laws for the notice requirements.

Deadlines by business type

The same rules play out differently by industry.

If you sell CBD, approval and monitoring are a larger concern. See our CBD payment processor approval guide.

Our perspective

We see deadline problems as process problems. Merchants rarely lose because the evidence does not exist. They lose because it was not found in time, or because the notice went to someone who was out of office.

Our approach has three parts. First, pricing that shows the real cost. With Network Offset Pricing, wholesale interchange is passed through, so each dispute fee and each transaction is visible in detailed transaction reporting. Second, reporting you can act on. When data on every transaction is available, finding the order, the descriptor and the date is quick. Third, support that knows the vertical. Restaurants, SaaS, eCommerce, healthcare and CBD each have their own dispute patterns, and a team that knows them helps you set the right retention periods.

Our advice is plain: assume the cardholder has more time than you do, keep records longer than you think you need, and answer every case early.

FAQ

Is there a time limit for chargebacks?

Yes, several. Federal rules require a written billing-error notice on credit cards within 60 days of the first statement showing the charge. Card networks apply their own reason-code windows, commonly described as about 120 days, with longer limits for some delayed-delivery disputes. Your processor then sets a separate, shorter deadline for your response.

Can a customer dispute a charge from three months ago?

Usually yes. The 60-day billing-error rule may have passed, but network windows and issuer policies often allow disputes at three months. Some claims and defenses can reach one year in certain U.S. situations. Approval depends on the issuer and the facts.

How long do I have to respond to a chargeback?

Use the due date on the case notice from your processor. It is set to fit inside the network's stage windows, so it is often shorter than the general figures you see in guides. Submit early so there is time to fix missing evidence.

What are the Mastercard chargeback rules for 2026?

Mastercard ties timing to the reason code and chargeback cycle rather than one universal number. Its guide also limits an issuer to one chargeback per presented amount, and Mastercard notes that its rules change. Confirm the current rules with your acquirer.

Do chargeback monitoring programs have their own time limits?

Yes. Programs set review periods, and your processor may require a remediation plan by a given date. Thresholds and fees change, so ask your acquirer for the current terms.
