Credit Suisse Admits to U.S. Tax Evasion Scheme, Agrees to Over $510 Million Settlement

Credit Suisse Services AG, a subsidiary of the former Swiss banking giant Credit Suisse Group, has pleaded guilty in a U.S. federal court to conspiring with American clients to hide more than $4 billion in offshore accounts. The admission marks a significant breach of a previous plea deal from 2014 and underscores the ongoing global effort to clamp down on tax evasion involving undeclared foreign assets.

A Repeated Pattern of Misconduct

The guilty plea stems from a wide-ranging investigation by the U.S. Department of Justice and the Internal Revenue Service (IRS). According to court filings, from 2010 to 2021, Credit Suisse AG—prior to its acquisition by UBS—deliberately helped U.S. taxpayers shield assets from U.S. tax authorities. These efforts included opening undeclared accounts, falsifying records, and even fabricating charitable donation documents to disguise the source of funds. Authorities reported over 475 undeclared accounts, with more than $1 billion held in non-compliant holdings.

This conduct violates the terms of a 2014 plea agreement, in which Credit Suisse paid $2.6 billion to resolve similar charges and committed to ending its involvement in undeclared offshore banking for U.S. clients. However, the latest findings reveal that the bank continued this behavior well beyond the agreed period, breaching the original deal and facing new charges as a result.

Additional Violations in Singapore Operations

Separate from the U.S.-focused misconduct, Credit Suisse AGs Singapore branch was found to have failed in properly managing accounts linked to U.S. persons. Between 2014 and mid-2023, Credit Suisse AG Singapore oversaw more than $2 billion in U.S.-related accounts without conducting the due diligence required under U.S. regulations.

The misconduct came to light in 2023, following the merger of UBS AG and Credit Suisse AG. UBSs internal review uncovered the unreported accounts, which were promptly frozen and disclosed to U.S. regulators. In response, Credit Suisse AG Singapore entered into a non-prosecution agreement with the U.S. Department of Justice, resolving the issue without criminal charges in exchange for cooperation and compliance commitments.

Penalties and Future Oversight

As part of the resolution, Credit Suisse Services AG will pay over $510 million in penalties, including restitution and asset forfeiture. The agreement does not protect any individuals from prosecution, signaling the Justice Departments intent to hold those responsible accountable beyond institutional fines.

UBS, now the legal successor of Credit Suisse, is required to fully cooperate with any further investigations. This includes disclosing any additional undiscovered accounts that may involve undeclared U.S. taxpayers.

As regulatory scrutiny intensifies, this case serves as a stark warning to other institutions that aiding in tax evasion—even indirectly—can result in significant financial and legal consequences.
