The majority of war tax stamps were produced during and immediately after World War I, primarily within the British Empire and its dominions. In most cases, they were produced by overprinting regular issues with "WAR TAX" or "WAR STAMP", though the overprint "WAR" was occasionally used (as in the issues of British Honduras). While they were meant to pay for the war tax only, they were often applied toward postage and registration fees. The following British colonies and dominions produced war tax stamps: Antigua, Bahamas, Barbados, Bermuda, British Guiana, British Honduras, Canada, Cayman Islands, Ceylon, Dominica, Falkland Islands, Fiji, Gibraltar, Gilbert and Ellice Islands, Gold Coast, Grenada, Jamaica, Malta, Montserrat, New Zealand, St. Helena, St. Kitts and Nevis, St. Lucia, St. Vincent, Trinidad and Tobago, Turks and Caicos Islands and Virgin Islands.
