French investigators raided Google's Paris headquarters on Tuesday as part of a probe over tax payments, according to a Reuters report. Google was not immediately available for comment.
France, Britain and other countries have long complained at the way Google, Yahoo! and other digital giants generate profits in their countries but have their tax base in other countries, where corporate tax rates are far lower.
France is seeking some 1.6 billion euros ($1.79 billion) in back taxes from U.S. Internet giant Google, criticised for its use of aggressive tax optimisation techniques, another finance ministry source had told Reuters in February.
Google had in January agreed to pay 130 million pounds in back taxes to Britain, prompting criticism from opposition lawmakers and campaigners.
