UBS pays €5 million to settle inherited Credit Suisse tax case

UBS will pay €5 million, around CHF 4.7 million, to close a Dutch tax case inherited from Credit Suisse. The Swiss bank announced the agreement with the Dutch public prosecutor’s office on Tuesday, September 22, 2026, bringing a long-running investigation into former Credit Suisse activity closer to its legal conclusion.

Dutch authorities examined potential criminal liability linked to allegedly incorrect tax returns involving 12 former Dutch clients. The returns at issue date from 2005 to 2015, a period when Credit Suisse operated independently of UBS. UBS absorbed its former rival in 2023 and assumed responsibility for its outstanding legal and regulatory matters.

The settlement carries a clear legal qualification. UBS said the agreement does not constitute an admission of criminal liability. The payment resolves the proceedings without the bank accepting criminal responsibility for the conduct under investigation.

The case adds another item to the legal workload created by the emergency takeover of Credit Suisse. For UBS, the immediate task is to settle the Dutch matter while separating inherited conduct from the compliance standards it says govern the combined bank today.

The investigation covered 10 years of tax returns and 12 former clients. Dutch prosecutors focused on possible criminal liability connected to information submitted to tax authorities during the period from 2005 through 2015.

The available details do not identify the former clients, the specific tax declarations under scrutiny, or the alleged inaccuracies in those returns. They also do not indicate the amount of tax that may have been at stake. Those limits matter because the settlement figure alone does not describe the underlying conduct or establish that every allegation was proven in court.

UBS’s payment follows an agreement with the Dutch public prosecutor’s office rather than a reported trial verdict. The bank has presented the outcome as a settlement of a legacy matter connected to Credit Suisse. Its legal position remains that the agreement is not an admission of criminal liability.

For Dutch authorities, the resolution closes a case linked to historic cross-border banking activity. For Swiss observers, it illustrates how tax compliance cases can remain active years after the transactions, returns, and client relationships under examination have ended.

UBS inherited the case when it took over Credit Suisse in 2023. The acquisition created the largest banking integration in modern Swiss history and transferred more than a balance sheet. UBS also acquired Credit Suisse’s unresolved legal exposures, including investigations involving conduct that predates the takeover.

The Dutch settlement shows the continuing cost of that inheritance. The €5 million payment is modest beside the scale of UBS and the broader financial consequences of the Credit Suisse rescue, yet each legacy case requires legal review, negotiations with authorities, and public disclosure. Settling a matter can also remove uncertainty over future proceedings and management time.

UBS has drawn a distinction between historic Credit Suisse conduct and its current compliance framework. The bank said it maintains a zero-tolerance policy on tax evasion and regularly updates its guidelines on tax compliance. That statement reflects the scrutiny Swiss banks face when serving clients with international tax obligations.

The settlement does not provide evidence that UBS itself committed the alleged conduct. It confirms that the bank, as Credit Suisse’s successor, accepted a financial agreement with Dutch prosecutors to resolve the inherited proceedings.
