I am thinking about applying for an Irish Passport (My Grandparents are Irish)vas I would like the option of being able to stay in europe for longer than 90 days. I currently have a UK Passport. If I manage to get an Irish Passport and spend less than 180 days a year in Ireland, do I just need to continue paying Tax in the UK. I don't plan on living in Ireland, just want the passport to travel to Europe.
