The term international offshore financial centre or IOFC is an alternative and now generally preferred term for a tax haven.
There are five basic classes of such jurisdictions as follows (the examples given being a non-exhaustive list):

1. Countries that have no income tax or that grant extensive tax exemptions:
Andorra, Anguilla, the Bahamas, Bahrain, Bermuda, Brunei (individuals), Campione, the Cayman Islands, the Cook Islands, French Polynesia, Grenada, Kuwait, Maldives, Monaco (individuals), Nauru, Oman (individuals only), the Turks and Caicos Islands, United Arab Emirates, Vanuatu

2. Countries that impose no income tax on foreign source income:
Botswana, Costa Rica, Djibouti, Dominican Republic, Ecuador, France (special rules for certain corporations), Guatemala, Hong Kong, Ireland (non-resident company), Jordan, Kenya, Lebanon, Lesotho, Liberia, Macau, Namibia, Panama, Swaziland, Uruguay, Venezuela

3. Seemingly high tax countries that can be used as low tax areas in certain respects, but also have certain tax treaty benefits:
Cyprus, the Netherlands, the Netherlands Antilles and Switzerland

4. Low tax financial centres and countries offering special incentives
and privileges:
Angola, Anguilla, Antigua, Barbados, the British Virgin Islands, Brunei, Cyprus, Gibraltar, Grenada, Guernsey, Hong Kong, Ireland, the Isle of Man, Jamaica, Jersey, Liechtenstein, Luxembourg, Macau, Madeira, Malta, the Marshall Islands, Mauritius, Montserrat, the Netherlands, Nevis, Philippines, Puerto Rico, Samoa, San Marino, Seychelles, Solomon Islands, Sri Lanka, St. Helena, St. Vincent, Switzerland
Note: Certain of these countries may also offer tax treaty benefits.

5. High tax countries offering special incentives and privileges.
Such countries are those offering incentives and could cover a high percentage of seemingly high countries. Most such countries would deny the appellation of IOFC.

There has been a vast increase in the number of persons participating in offshore activities. There is a hitherto unimaginable proliferation of offshore companies and trusts, with very many expatriates changing residence for tax reasons.

The increase in the number of countries offering tax haven or finance centre possibilities is due in major part to the seeming high tax jurisdictions now actively seeking a slice of the world’s offshore business. The widened scope of offshore transactions and operations has favored an ongoing merging of onshore and offshore.
