The cruelest way to lose a dispute is not to have it denied — it is to file one day late and have the bank refuse to open the case at all. Dispute deadlines are hard cutoffs: once the window closes, the issuer generally does not have to consider the claim. The good news is that missing one is almost entirely preventable, because the failure is usually not the date math — it is forgetting.
This guide gives you a small, practical system: know the two clocks, set two reminders, and know exactly what to do when each one fires.
In our experience the pattern is always one of three:
All three are fixed by the same habit: a concrete date on your calendar, with reminders before the date — not on it.
Most disputes run under two overlapping clocks. The binding deadline is the earlier of the two.
Visa, Mastercard, American Express and Discover each publish a filing window of up to 120 days. It usually starts on the transaction date — but for goods or services you never received, it starts at the expected delivery date instead (typically capped at 540 days from the transaction). Run your dates through the deadline calculator rather than guessing which start date applies.
Separate from the networks, US federal law gives you 60 days from the statement date to dispute a billing error in writing — the Fair Credit Billing Act for credit cards (15 U.S.C. §1666) and the Electronic Fund Transfer Act / Regulation E for debit cards. Written matters: a phone call alone does not satisfy it. A secure message inside your banking app generally counts as writing, and it creates a dated record.
The takeaway: always file before the earlier deadline, and always file in writing, even if you also call.
The moment you have your deadline — from the calculator or your bank — put it on your calendar with two alerts:
Our tools do this for you: the calculator result page has a "Remind me before my deadline" block that adds the deadline to Google Calendar or downloads an .ics file with both reminders (7 days and 1 day before, 9:00 AM your local time) built in — no account, nothing stored, everything in your browser. The checker tools offer the same block once you enter your deadline date.
If you use your phone's calendar instead, set the same two alerts manually. The medium does not matter; the two alerts do.
Seven days out is preparation time — not filing time. Your job:
One day out, there is exactly one job: file.
Do not let "I need one more document" push you past the date. File with what you have; most issuers let you add evidence to an open case.
First, file anyway — issuers sometimes accept late disputes at their discretion, and a polite, documented late filing has occasionally worked where silence never does. Second, know the backup routes:
Sources: 15 U.S.C. §1666 (FCBA billing-error notice); 15 U.S.C. §1643 (unauthorized-use liability cap); 12 C.F.R. §1005.11 (Regulation E error resolution); published Visa, Mastercard, American Express and Discover dispute time limits (up to 120 days); UK Consumer Credit Act 1974, §75.
Both. US federal law (FCBA for credit cards, Regulation E for debit) generally requires written notice of a billing error within 60 days of the statement that showed the charge. Card networks separately allow up to about 120 days from the transaction date to file. The safe move is to file before the earlier of the two.
At minimum two: 7 days before (to gather evidence and draft your filing) and 1 day before (the last full day to actually file). Many people also add one at 30 days before. Calendar alerts you set today cost nothing and are the difference between a timely filing and a closed window.
A phone call starts the process, but the US federal 60-day protection (FCBA) requires written notice — follow up any call in writing (a secure message in your banking app usually counts) and keep a dated copy.
File anyway — issuers sometimes accept late disputes at their discretion. In the UK, Section 75 credit-card claims can run up to 6 years from the breach. Escalation options include the CFPB (US), the Financial Ombudsman (UK), and small claims court for larger amounts.
Yes. The "Remind me before my deadline" block creates the reminder in your own calendar app (Google Calendar link or a downloaded .ics file). Your dates never leave your browser — nothing is sent to or stored by Chargeback Clock.
