Retire in Ireland

Americans are non-visa-required, so you don't need the D-Reside entry visa. You apply for Stamp 0, receive a Conditional Letter of Offer, travel to Ireland, then register in person for your Irish Residence Permit. Budget a few months for the process.

No. Stamp 0 doesn't allow paid work or running a business unless you get specific permission. You can live on passive income like pensions and investments, and you're free to volunteer.

You'll need a verifiable income of at least €50,000 per person per year (€100,000 for a couple), plus access to a lump sum roughly equal to the price of an Irish home, which runs well north of €300,000. The money has to come from pensions or readily accessible funds, not speculative investments, and an Irish accountant has to certify it before you apply.

Probably some in each, but treaties soften it. If you're an Irish tax resident but not Irish-domiciled, foreign income and gains are generally taxed only when you bring them into Ireland. Under the US-Ireland treaty, US Social Security is usually taxed only in Ireland, though you still file a US return. Get advice for your own situation.

No, and this is the big catch. Stamp 0 is a temporary permission that doesn't count toward long-term residency or naturalisation. You renew it one year at a time. If citizenship is your goal, it's the wrong stamp.

No. Stamp 0 holders can't use public hospitals or state benefits, so private medical insurance is mandatory. Cover needs to be at or above the VHI Plan D level, with in-hospital cover of at least €25,000, and you keep it for every renewal.
