The local IRS considers that most of this revenue is sold though Google employees located in France that issues invoices in French language. Therefore it seeks to requalify the amount of taxes paid by Google up to 169 M euros / years from the 5 M euros actually paid.
Accounting information was seized in Google French premises. Google lawyers tried to invalidate the procedure
Looks like France may get a big one time payment but future customer will have to call Irland and receive invoice in English to be served.
