Ireland vs United Kingdom
Side-by-side comparison of Ireland and United Kingdom: residency, citizenship, tax, cost of living and lifestyle. Updated 2026.
Ireland versus the United Kingdom — close geographic neighbours with deeply intertwined histories but increasingly divergent migration regimes since Brexit. Ireland remains in the EU with full freedom of movement; the UK has implemented a points-based immigration system. Ireland's Stamp 0 retirement and Investor Pathway differ structurally from the UK's Innovator Founder and Skilled Worker visa categories. Tax: the UK abolished its non-dom remittance regime for new residents from April 2025 and replaced it with a four-year FIG window; Ireland retains the remittance basis for non-doms indefinitely with material consequences for cross-border families.
