Reunification with Ireland Estimated to Cost €20 Billion Annually Over 20 Years, Requiring Tax Hikes and Public Spending Cuts

A united Ireland would cost €20 billion annually for 20 years, largely funded by the Republic, says new study
There would need to be substantial tax hikes (up to 25%) and cuts to public spending to fund reunification
It would take at least 20 years to align productivity between the North and Republic
Northern Ireland would benefit from EU single market access post-unification
Critics argue the estimates are based on unrealistic assumptions about immediate reunification without a transition period
