How Long Does It Take to Dispute a Transaction?

How long it takes to dispute a transaction depends mostly on which card you used and how complicated the charge is. Debit card disputes can wrap up in as little as 10 business days, or run 45 to 90 days if the bank needs more time. Credit card disputes take longer on the front end but are capped by federal law at two billing cycles, and never more than 90 days. Both share one deadline that controls everything else: you generally have 60 days from the statement date to report the problem.

The 60-Day Filing Window

Miss this and you lose the federal protections that make the rest of the timeline work.

For credit cards, the Fair Credit Billing Act requires you to send a written notice of the billing error to your card issuer within 60 days of the date the issuer sent the statement containing the charge. The notice must go to the address your issuer designates for billing inquiries, not the payment address. A phone call does not count.¹

For debit cards, Regulation E gives you 60 days from the date your bank sent the statement showing the error. You can report the problem by phone, though the bank can ask you to follow up in writing within 10 business days. If it does and you don’t, the bank isn’t obligated to issue provisional credit while it investigates.²

Credit Card Disputes: Up to 90 Days

Once your written notice reaches the issuer, two deadlines apply. The issuer must send you a written acknowledgment within 30 days of receiving your notice, unless it resolves the dispute entirely within that same 30 days.¹ It must then complete its investigation and either correct the error or explain in writing why the bill is accurate within two complete billing cycles, and no later than 90 days after receiving your notice.³

While the investigation is open, you don’t have to pay the disputed amount or related finance charges. The issuer cannot try to collect that portion, and it cannot report your account as delinquent based on your withholding payment. You still owe the undisputed portion and should keep paying it to avoid late fees.³

If the issuer misses any of these deadlines, it forfeits the right to collect up to $50 of the disputed amount, even if the charge turns out to be valid.⁴

Debit Card Disputes: 10, 45, or 90 Days

The debit card track is generally faster on the initial review. Once your bank receives your error notice, it has 10 business days to investigate. If it finds an error, it must correct it within one business day and report the results to you within three business days.²

If the bank needs more time, it can extend the investigation to 45 calendar days, but only if it provisionally credits your account for the disputed amount (plus any applicable interest) within the initial 10 business days. That credit gives you access to the money while the review continues.⁵

Three categories of transactions get the longest window, up to 90 calendar days: point-of-sale debit card purchases, transfers initiated outside the United States, and transactions on a new account (opened within the previous 30 days). For new accounts, the bank has 20 business days rather than 10 to issue the provisional credit.⁵

Provisional credit is not permanent. If the bank ultimately concludes no error occurred, it can reverse the credit, but it must notify you in writing, explain its findings, and tell you that you can request the documents it relied on. It also has to honor checks and preauthorized payments from your account without charging overdraft fees for five business days after the reversal.²

Why Some Disputes Take the Full 90 Days

Federal law sets your bank’s deadlines, but a separate set of rules runs in the background between the banks and the merchant. Card networks control how long the merchant has to fight back, and that back-and-forth often accounts for the biggest chunk of the total timeline.

Under Visa’s process, a merchant has 30 days to respond to a chargeback with evidence supporting the original transaction. If that response doesn’t settle things, the dispute can move into pre-arbitration (another 30-day window on each side) and finally arbitration, where Visa issues a ruling within 10 days.⁶ Mastercard allows up to 45 calendar days for a second presentment on most transactions, with a separate 30-day pre-arbitration window.⁷

If a merchant misses its response deadline, the card network generally resolves the dispute in the consumer’s favor by default. When a merchant does respond with evidence, such as a signed delivery confirmation or a usage log, the issuing bank weighs it against your claim, and that review is where most of the calendar goes.

A Realistic Timeline From Start to Finish

Day 1: You file the dispute with your bank, within 60 days of the statement date.
Days 1–10: Debit card banks investigate or issue provisional credit and extend. Credit card issuers begin review.
Days 10–30: Credit card issuers send written acknowledgment. Merchants get notified of the chargeback.
Days 30–45: Merchants submit rebuttal evidence (30 days for Visa, up to 45 for Mastercard). Issuing banks weigh both sides.
Days 45–90: Complex cases (international transactions, point-of-sale debit purchases, new accounts) may still be under review. Credit card disputes must be fully resolved by day 90.

Straightforward disputes where the merchant does not respond often resolve in two to four weeks. Contested disputes that go through a full merchant rebuttal and evidence review tend to take 45 to 90 days. Disputes that escalate to card network arbitration can take longer, though most consumers never reach that stage.

If the Dispute Is Denied

A denial is not the end. For debit card disputes, the bank must send a written explanation of its findings and tell you that you can request copies of the documents it relied on. The bank has to hand those over promptly once you ask.² For credit card disputes, the issuer must similarly explain its reasoning in writing and provide documentary evidence of the debt on request.¹

Review the explanation and the documents carefully. If the bank’s evidence is thin or the investigation missed something, you can escalate by filing a complaint with the Consumer Financial Protection Bureau. The agency forwards the complaint to the institution, which must respond. Complaints go through consumerfinance.gov or (855) 411-2372. If the dollar amount justifies it, small claims court is another option; filing fees vary by jurisdiction but are generally modest, and you don’t need a lawyer.
