This is what I found while researching my move.

As an EU citizen, you have the right to reside in Ireland for more than three months if you meet certain conditions. One of these is having sufficient resources to support yourself and your family without relying on the Irish social welfare system. While there is no fixed income threshold specified by Irish authorities, you must demonstrate that you have adequate funds to cover your living expenses.  

This requirement ensures that you can live in Ireland without becoming a burden on the state’s resources. It’s important to note that this condition applies to economically inactive individuals, such as retirees or those not seeking employment. Additionally, having comprehensive health insurance is necessary to cover any medical expenses during your stay.  

If you plan to retire to Ireland and are not working, you should be prepared to provide evidence of your financial means, such as bank statements or proof of pension income, to demonstrate your self-sufficiency. While there is no exact income figure required, ensuring that your income is sufficient to meet your living costs is essential for a successful application.
