Self Employment & tax
It may be considered illegal self employment in Spain but I don't think that they can force a UK resident who only sets foot in Spain for a few hours at the start and end of a duty cycle to pay income tax, the EU regulation 833/2004 however gives the Spanish some sort of lever to apply the social taxes but only if they only read the parts of the regulation that support their case and not the parts that don't.
A getting on and off an aircraft at one place along with the occasional night in a hotel is hardly the basis for taxing someone, being resident is, that is why I pay my taxes in my country of residence and as long as I comply with the states tax regulations it is nothing to do with Spain or any other EU state that wants a bit of the action.
In short in my case it is for the UK tax authority's to tax me according to the UK law and my responsabiltity to pay the correct amount of tax.
