I am british, based in Portugal on a Portugese contract. I am a full resident paying Portugese tax and social security and I am also a Non Habitual Resident. Pilot is not on the list so we do not qualify for the 20% tax rate on income however I keep it as there are some other benefits and if they suddenly decide to add pilot to the list I hopefully will become eligible for the rate. You must complete the NHR application before filling your first tax return in Portugal as a resident I believe. I would not pay anyone to do this as all the info is there.
