period between after the late 1950s and up to the mid-1970s can be viewed as a period of radical change in the evolution of the Irish Corporate Taxations system. The increasing realisation of the government that Ireland would be entering into an age of increasing free trade encouraged a number of reforms of the tax system. By the mid-1970s, a number of amendments, additions and changes had been made to the CPT, these included fifteen-year tax holidays for exporting firms, the decision by the government to allow full depreciation in 1971 and in 1973, and the Section 34 of the Finance Act, which allowed total tax relief in respect of royalties and other income from licenses patented in Ireland. This period from c.1956 to c.1975, is probably the most influential on the evolution of the Irish corporate tax system and marked the development of an 'Irish' corporate tax system, rather than continuing with a version of the British model. This period saw the creation of Corporation Tax, which combined the Capital Gains, Income and Corporation Profits Tax that firms previously had to pay. Future changes to the corporate tax system, such as the measures implemented by various governments over the last twenty years can be seen as a continuation of the policies of this period. The introduction in 1981 of the 10% tax on manufacturing was simply the easiest way to adjust to the demands of the EEC to abolish the export relief, which the EEC viewed as discriminatory. With the accession to the EEC, the advantages of this policy became increasingly obvious to both the Irish government and to foreign multi-nationals; by 1982 over 80% of companies who located in Ireland cited the taxation policy as the primary reason they did so. Charles Haughey low-tax economy (1987–2009) The Irish International Financial Services Centre ("IFSC") was created in Dubin in 1987 by Taoiseach Charles Haughey with an EU approved 10% special economic zone corporate tax rate for global financial firms within its 11-hectare site. The creation of the IFSC is often considered the birth of the Celtic Tiger and the driver of its first phase of growth in the 1990s. In response to EU pressure to phase out the 10% IFSC rate by the end 2005, the overall Irish corporation tax was reduced to 12.5% on trading income, from 32%, effectively turning the entire Irish country into an IFSC.
