“A new standard of exchanging information on tax is expected to be introduced in countries belonging to the OECD. The new system will probably by based on US anti-tax evasion legislation known as FATCA, according to Pascal Saint-Amans, director of the OECD’s Centre for Tax Policy and Administration. Saint-Amans spoke to swissinfo.ch about the plans to introduce automatic exchange of tax information which the OECD intends to present for scrutiny next February. This future international standard is considered to be much more exacting than the current model and incompatible with the present system in Switzerland.”
