TheRepublic of Panama is one of the oldest and best-knowntax havens inthe Caribbean, as well as one of the most established in the region.[1] Panama has had a reputation fortax avoidance since the early 20th century, and Panama has been cited repeatedly in recent years as a jurisdiction which does not cooperate with international tax transparency initiatives.
Panama's offshore sector is intimately tied to thePanama Canal, which has made it a gateway andentrepôt for international trade.[2] There are strong similarities between Panama and other leading tax havens like Hong Kong, Singapore and Dubai. On paper at least, Panama has the largest shipping fleet in the world, greater than those of the US and China combined, according to theTax Justice Network.

A 2014 investigation by journalistKen Silverstein published inVice Magazine explains how Panama came into being, with US help:
In 1903, the administration of Theodore Roosevelt created the country after bullying Colombia to hand over what was then the province of Panama. Roosevelt acted at the behest of various banking groups, among themJ. P. Morgan & Co., which was appointed as the country's official "fiscal agent".[3]
TheRoosevelt administration sought to foment armed rebellion by Panamanian nationalists,[4] forcing Panama away from a politically fragile Colombia. Roosevelt achieved this goal with the help ofWilliam Nelson Cromwell, a well-connected US Republican lawyer and also legal counsel for JP Morgan's railroad interests. The administration's key objective was allegedly to install a pro-US Panamanian government that would secure US rights over thePanama Canal.[5] TheHay–Bunau-Varilla Treaty resulted, establishing permanent U.S. rights to aPanama Canal Zone several miles wide, across the neck of the isthmus. Panama became independent from Colombia the same month, and the Panama Canal opened in 1914.[6]
According to a 2013 academic study published by the Norwegian Center for Taxation, Panama's reputation as atax haven began in the year 1919, when it began registering foreign ships in order to helpStandard Oil avoid US taxes and regulations; other US ship owners followed, some seeking to avoid the higher wages and better working conditions imposed by US legislation such as the Seaman's Act and safety standards for sea vessels.[7] Also, during theProhibition era, US passenger ships were allowed to serve alcohol to their customers without breaking the law if they had Panamanian registration.[8]
Within a few years, Panama extended its minimalist approach to taxation, regulation and financial disclosure requirements to the world ofoffshore finance. According to the study, "Wall Street interests helped Panama introduce lax company incorporation laws, which let anyone start tax-free, anonymous corporations, with few questions asked".[8]
For decades, offshore finance had a relatively modest profile in Panama, but it took off in the 1970s as world oil prices surged. During this time, the Republic of Panama passed legislation "entrenching corporate and individual financial secrecy".[9]
By 1982, partly attracted by business opportunities deriving from the Panama Canal and its free trade zone, more than 100 international banks had offices in Panama City.[9]
According toInvestopedia: "Panama's offshore jurisdiction offers a wide array of excellent financial services, including offshore banking, the incorporation of offshore companies, registration of ships and the formation of Panama trusts and foundations."[1] In Panama, no taxes are imposed on offshore companies which engage in business solely outside of the jurisdiction; therefore, the companies which are incorporated in the Republic of Panama and the owners of these companies are exempt fromcorporate taxes,withholding taxes,capital gains tax,local taxes,estate taxes andinheritance tax. However, businesses within Panama itself are permitted to conduct business there so long as the company pays its local taxes.[1]
Panama has been cited repeatedly in recent years by theState Department of theUnited States and theInternational Monetary Fund (IMF) as a jurisdiction which does not cooperate with international tax transparency initiatives due to the legislation which regulates the country's offshore jurisdiction and financial services.[10] Panama has over 350,000international business companies (IBCs) registered, the third largest number in the world afterHong Kong and theVirgin Islands. Alongside incorporation of IBCs, Panama is active in forming tax-evading foundations and trusts, insurance, and boat and shipping registration, according to theTax Justice Network.[2]

An extensive amount of legislation currently exists in the Republic of Panama to protect corporate and financial privacy. However, organisations such as theTax Justice Network and otheradvocacy groups andnon-governmental organisations state that the main intention of these laws is financial secrecy, as opposed to privacy.[11][12]
The names ofshareholders of Panamanian corporations, trusts and foundations are still not required by law to be publicly registered. Panama has noexchange controls: this means that for individual clients of Panama's offshore banking, as well as for offshore business entities incorporated in Panama, there are no limits or reporting requirements on money transfers into or out of the country.[1][9]
Panama also has very strict banking secrecy laws: for example, it is forbidden for Panamanian banks to share any information about offshore bank accounts or account holders, except under special circumstances instigated by the Panamanian authorities. Such regulation has made it difficult to investigate the true extent of thePanama Papers leak, as severe criminal penalties are enacted to individuals who breach confidentiality.[1][9]
Despite this, Panama does not appear on theTax Justice Network's top ten list for financial secrecy,[13] with Alex Cobham of Tax Justice Network saying "There is a double standard: many developed countries host or support jurisdictions where there is an absence of financial transparency".[14]
Pascal Saint Amans, Director of theCentre for Tax Policy and Administration in theOECD[15] said: "From the standpoint of reputation, Panama is still the only place where people still believe they can hide their money."[9][2] Writing forVICE News,Ken Silverstein explained theMossack Fonseca history in the region: "These laws attracted a long line of 'dirtbags' and dictators who used Panama to hide their stolen loot, includingFerdinand Marcos,'Baby Doc' Duvalier, andAugusto Pinochet. WhenManuel Noriega, commander of thePanama Defence Forces, took power in Panama in 1983, Silverstein said, Noriega essentially nationalised the money-laundering business; he partnered with theMedellin drug cartel and gave it free rein to operate in the country."[9][3]
In theUnited Kingdom,Private Eye used data collected from theLand Registry to create "an easily searchable online map ... of properties in England and Wales owned by offshore companies. It reveals for the first time the extent of the British property interests held by companies based in tax havens." Most of these properties are tax avoidance vehicles and in some cases also to conceal wealth of dubious origin."[16]
A 2003 examination of tax havens byJeffrey Robinson quotes a US Customs official as saying:
[Panama] is filled with dishonest lawyers, dishonest bankers, dishonest company formation agents and dishonest companies registered there by those dishonest lawyers so that they can deposit dirty money into their dishonest banks. TheFree Trade Zone is the black hole through which Panama has become one of the filthiest money laundering sinks in the world.[17][2][18]
Theadvocacy group theTax Justice Network has describedPanama as "the recipient of drugs money from Latin America, plus ample other sources of dirty money from the US and elsewhere".[17] It said "now is a good moment to draw attention to how Panama developed as a secrecy jurisdiction and how it continues to provide full service – wash, rinse and dry – to crooks and money launderers from around the world."[17][19]
Ramón Fonseca Mora, the co-founder ofMossack Fonseca, told theNew York Times: "I assure you there is more dirty money in New York, Miami and London than there is in Panama".[14] The United States isan alleged tax haven despite theForeign Account Tax Compliance Act.[20] The US has refused theCommon Reporting Standard set up by theOrganisation for Economic Co-operation and Development.[21] This means the US receives tax and asset information for American assets and income abroad, but does not share information about what happens in the United States with other countries; in other words, the US has become attractive as atax haven.[22]
