Geneva, Jun 17 - The Swiss Parliament today gave approval to amendments to tax treaties with countries, including India, that makes it easier for them to access information about the illegal funds held by their nationals in Swiss private banks. The upper house of the Swiss Parliament endorsed amendments to double-taxation agreements in line with internationally applicable standards. Governments which have signed DTAAs can now secure easy legal assistance and information as well as identify an account holder from their territories by providing an IBAN number or social security number.
