For almost 3 years I have been a resident in Ireland. I live, work and pay my taxes here. On January I am going to start my new job in Northern Ireland, but I will still live in ROI (my wife will still work here, my son will still attend primary school in ROI). My question – what might be the implications of this regarding my taxes? Essentially personal taxes in NI are little bit higher than in ROI – can I avoid it?
