Credit Suisse is expected to pay almost $2.5 billion to settle a probe into how the firm allegedly helped Americans evade taxes, including roughly $700 million to US regulators and approximately $1.7 billion to the Justice Department, according to people familiar with the discussions.

Under tentative terms of a deal still being discussed, the bank would plead guilty to US allegations and pay the Federal Reserve about $100 million and the New York State Department of Financial Services approximately $600 million, these people said. The settlement could come as early as next week.
