I don't realy get this. Say that you're based in Spain for example.
You have to pay tax on Ireland, and then in Spain to? If you do deductions in your company in Ireland, for example the rating, a headset and so on, will this deduction follow you to spain or will you have to pay more tax in spain instead?
How do you contractors out in europe do, where do you pay taxes and what does the percentage end up in with all the deductions you are allowed to do?
