Get round the tax issue, risky business these days.
Three former colleges of mine got letters from their national tax office a while ago. They where accused of not reporting correct amount taxable income. Two of the guys were given the option to pay each a fine of € 200.000,- or face criminal prosecution. Their lawyer adviced them to take the 200 K fine since the documentation provided by the tax office was massive. The documentation was released by the end user low cost airline well known across Europe.
The last college brought his case in for the court. He is fighting his case all at his own expense. He was never given the option of paying off his problem since he was supposed to pay his tax to a different country.
It is interesting to see that the airlines, when approached by the tax offices, release all info and cover their own back.
