If your contracted to brookfield and your only customer is Ryanair for a long period of time with possible clauses of you only flying for them regarding public transport hours.
Wouldn't a government tax authority either in Ireland or your home country, take a position of you being an employee of Ryanair. Also, assuming your main place of work or rather base. How come you dont pay tax in that location? Is it the whole Irish company and being employee of it.
I spend a lot of time in Norway working and offering my services in another profession. Although I live in another country, I have to pay tax also in Norway, partly because its outside of the EU.
I find it quite interesting in how this all works and assume the EU will be trying to look into this and reading a few of the threads of this forum regarding Ryanair and France etc.
