More Europe Banks Identified in US Tax Probe: Report

Nearly 10 more Swiss and other European banks holding wealthy US citizens accounts were identified using a tax-evasion amnesty program in the US, the Wall Street Journal reported on its Web site Wednesday.

Swiss banks Credit Suisse, Julius Baer, Zurcher Kantonalbank and Union Bancaire Privee are among the banks named in the voluntary disclosures, the newspaper said.

Contacted by CNBC, Credit Suisse and Julius Baer declined to comment.

The paper said other banks either declined comment or weren't immediately available.

The disclosures don't signal wrongdoing at the banks, as they may mean that a US citizen simply kept money with a European bank and now wants to report it, according to the Wall Street Journal.

Applicants to the tax amnesty program, which closes on September 23, must list all "accounts or assets where you have control or are a beneficial owner of the account or assets."

They must also disclose the dates when the accounts were opened or closed.

The US is building criminal cases against more than 150 US customers of UBS as part of a crackdown on tax evasion.
