Google staff pursued over unpaid taxes.
REVENUE is pursuing millions of euro in unpaid tax from workers in some of the biggest companies based here.
RTE News reported the move is focusing on employees who cashed in company shares but failed to pay tax.
Some staff at Google's Dublin office are among those who have been asked to pay taxes owed on profits made from share options.
Revenue is calling this a "compliance programme" for people who exercised a share option within their company in recent years.
The responsibility for paying tax on the profits falls to the workers not the firm.
Revenue expects the move to yield a figure in the low millions.
