Swiss banks accused of helping Americans to dodge taxes have been summoned to a parliamentary committee hearing this week at which they will be asked to explain their actions, Swiss newspaper NZZ am Sonntag reported on Sunday.
The hearing is set to take place on Monday and Tuesday, the newspaper said.
Representatives from the banks will be asked to explain which rules they used for their business with private U.S. clients in America and Switzerland.
The United States has been pushing for Switzerland to supply information on bank clients who may have evaded taxes.
