Western Europe, I believe all countries as France, Germany, Netherlands act in a similar way.
The trigger was a relationship with a tax paradise such as Hong Kong, Malta, UAE,..
Annual revenue only around 10 million usd, they seek a similar amount in taxations and contact all other tax authorities we have a related business with requesting exchange of information. The structure was set up correctly and all the work force is located in the other jurisdictions, but once they start such an operation and even they didn't︀ find what they expected or the reason they used for the raid is proven false,︁ they will still make sure to find many other things and make tax claims of︂ millions are sent.
So even you set up your structure well, plan everything correctly, once︃ tax authorities at this level take action you can expect high bills in legal fees,︄ lengthy legal cases and tax bills that easily reach several millions which you then have︅ to dispute in court by providing loads of evidence.
Every case is different but know︆ this situation is possible as soon as they link you to a tax heaven. Something︇ we never expected (audit yes, raids no)
