Citi provisional credit: when do you get your money back?

"Provisional credit" is a temporary refund while your dispute is investigated. Whether Citi owes you one, and by when, depends entirely on whether the disputed charge was on a debit card (Regulation E) or a credit card (Regulation Z).

Debit card · Reg E

Within 10 business days

If Citi cannot finish investigating a debit card dispute within 10 business days, Regulation E (12 CFR 1005.11(c)) requires it to provisionally credit your account within 10 business days and give you full use of the money while it investigates — up to 45 days, or 90 days for point-of-sale and foreign transactions. Accounts opened in the last 30 days get 20 business days instead of 10.

Credit card · Reg Z

No fixed deadline

Regulation Z (12 CFR 1026.13) sets no provisional-credit deadline for credit card disputes. Instead, while Citi investigates a billing error you filed within 60 days, it cannot make you pay the disputed amount or report it delinquent, and it must resolve the dispute within two billing cycles (no more than 90 days). Any earlier credit is a courtesy, not a legal right.

Does Citi give provisional credit while a dispute is investigated?▼

It depends on which card.

For a Citi credit card dispute, Regulation Z (12 CFR 1026.13) sets no provisional-credit deadline; instead, you are not required to pay the disputed amount and it cannot be reported delinquent until the dispute is resolved, within two billing cycles (no more than 90 days).
