TWITTER has acknowledged Ireland as one of two significant tax bases for the company ahead of the social media company's €750m public share flotation,
"The material jurisdictions in which the company is subject to potential examination by taxing authorities include the United States, California and Ireland," said a regulatory document filed in advance of the market flotation.
"The company believes that adequate amounts have been reserved in these jurisdictions. The company's 2007 to 2012 tax years remain subject to examination by the United States and California, and its 2011 to 2012 tax years remain subject to examination in Ireland."
Twitter recently announced plans to double its Dublin office workforce from 100 to 200.
While there are more sales and marketing jobs than technical roles listed, the social networking giant is creating its first engineering positions outside its Californian headquarters.
Twitter bosses emphasised it is the quality of the Irish workforce, not the tax structure here, that has resulted in its decision to expand in Dublin.
Ireland has come under pressure from governments around the world who are furious about the way multinationals use our tax laws to avoid paying taxes in other high-tax countries.
Last week, Google disclosed that it paid €17m on €15.5bn of revenue booked through its Dublin office. US multinational firms have courted controversy this year over the modest levels of tax paid through their Irish subsidiaries.
Meanwhile, Twitter has revealed it has racked up €324m in accumulated losses, with a €47m loss on €190m revenue in the first six months of this year. It also revealed a slowdown in advertising growth, with ad revenue down 13pc from Q4 2012 to Q1 2013.
The micro-blogging site makes money through advertising on its service. This takes the form of promoted content, which allows companies to purchase positions on the service's information stream according to user searches or keywords.
