Cui bono?
Simple: the pilots and Lufthansa and the german airlines that have regular vertrag...
I am working as a consultant on this matters (side business in order to get out of being a propilot) for few italian CPTS/FOS.
Let me say it clear: pilots are naives. They think that the model "a la RYR" that paid off very well at the end of last century and beginning of this, will be sustainable for the future.
Let me tell you this(if you don't already know): in many countries tax evasion has a statue of limitation of 10 years(10!!!!!).
Social contributions dues are considered taxes in some of these countries.
Some of these gentleman are finding themself in deep **** right know. Some might even face the possibility of imprisonement.
Few might not even claim any damage against contract agencies. (Free advise for everyone: DO NOT SIGN A CONTRACT/AGREEMENT WITCH FORCE YOU INTO ARBITRATION IN CASE OF DISPUTE. Thanks me later)
Tax planning is a very complex matter, requires profesionnal with particular experience and is not for the faint of heart.
Another free advise(I am vey generous today): take whatever number the agency is offering to you and divide it by 2. That's more or less the netto you will get. More is a bonus.
Furthermore, consider this: for tax porpuses is always better direct employement with airlines instead of agencies. The double tax agreement are always very pro direct employement with airlines/ships operators...not so much with agencies....
Take care out there
