The head of the IDA says Ireland could win more foreign investment if taxes were lower here.
Its chief executive Barry O'Leary says setting out a clear plan of how the government would cut taxes for workers would bring more firms to Ireland.
He was launching the IDA annual report for 2013, in which the agency says it created over 13,000 jobs for Ireland.
It also found that over 100 investments were secured in the first six months of 2014, compared to 70 at the same time last year.
Of those investments secured, 40% have come from companies investing in Ireland for the first time - with the remainder represented by expansions and transformations by existing firms.
Thee IDA claims the projects approved during the first half of 2014 will lead to the creation of 8,000 jobs this year and over future years, as the companies roll out investment plans.
During the first six months of the year, there were investments in various locations including Limerick, Dundalk, Athlone, Galway and Mayo.
The report says that at the end of 2013 there were 161,112 people now working at IDA client companies - a new record for the FDI sector in Ireland.
Barry O'Leary says that the tax base is something raised by many of the firms considering an investment in Ireland.
