Explanation:

A tax haven is generally an offshore country that offers foreign individuals and businesses little or no tax liability in a politically and economically static environment.

• Characteristics of tax haven countries generally include no or low-income taxes, minimal reporting of information, lack of transparency obligations, lack of local presence requirements, and marketing of tax haven vehicles.
• Generally, tax havens do not require residency or business presence for individuals and businesses to benefit from their tax policies.
• Individuals and corporations can potentially benefit from low or no taxes charged on income in foreign countries where loopholes, credits, or other special tax considerations may be allowed in accordance with the law.
• Worldwide, there are some programs in place to increase the enforcement of offshore investment reporting.
• The Standard for Automatic Exchange of Financial Account Information, developed by the OECD with G20 countries, represents the international consensus on automatic exchange of financial account information for tax purposes, on a reciprocal basis.

Hence both statements 1&3 are correct.
