Buying in Dublin vs the US: costs and taxes

Ireland will sell you a house in Rathmines without a second look at your passport. The hard part is the mortgage rules, and then two tax systems that both want a say when you sell.

The short version

Americans can buy in Ireland on the same terms as Irish citizens. There's no foreign-buyer approval or surcharge.
Stamp duty is low: 1% up to EUR 1 million, 2% on the slice to EUR 1.5 million and 6% above [1].
The Central Bank caps borrowing: first-time buyers at 4 times income and 90% of the price, everyone else buying a home at 3.5 times, and buy-to-let at 70% [2].
Ireland taxes gains at 33%, but your main home is usually exempt under principal private residence (PPR) relief [3][4].
The IRS taxes your worldwide gain anyway. Section 121 shelters up to USD 250,000 (USD 500,000 joint) [5], and Irish tax on a rental's gain can usually be credited [6].

USD conversions use the Federal Reserve H.10 rate of October 30, 2026 (USD 1.1163 per euro), rounded.

Can Americans buy in Dublin?

Yes. Ireland has no foreign-ownership approval, no residency test and no surcharge for non-citizens. You can buy a redbrick in Drumcondra or an apartment in the Docklands on a Critical Skills permit, a Stamp 4, an Irish passport through your grandparents or no Irish status at all.

A Dublin purchase runs differently from a closing in Boston:

Offers aren't binding. Bidding goes through the seller's agent, and "sale agreed" means nothing legally until contracts are signed. Gazumping (a higher offer after yours was accepted) is legal, if maddening.
Your solicitor does the heavy lifting. A solicitor checks title, raises questions on planning and the building, and handles the closing and the stamp duty return. Get a structural survey too.
Apartments come with a management company. Ask about the annual service charge, the sinking fund and any fire-safety or defects work, a real issue in some Celtic Tiger-era blocks.
Mortgage approval in principle comes first. Irish sellers' agents want to see it before taking your bid seriously.

Getting a loan: Irish bank or US lender?

In Dublin. Irish lenders work under the Central Bank's mortgage measures. Since January 1, 2023, first-time buyers can borrow up to 4 times gross income with a 10% down payment; second and later buyers 3.5 times income with 10% down; buy-to-let buyers need 30% down. Lenders can go over the limits for a small share of loans each year [2]. Banks generally want you living and working in Ireland, with Irish payslips and some time in the country. If you have income in dollars, expect a lender to discount it or not count it at all.

That 4-times cap is the reality check. A couple earning EUR 150,000 together can usually borrow about EUR 600,000 as first-time buyers, which is less than many Americans expect coming from a US system that runs on debt-to-income ratios.

Back home. Using equity in a US home, or taking a stateside mortgage and paying cash in Dublin, is the other route, but US lenders get cautious with euro income and an overseas address. Our guide to US mortgages for Americans living abroad has the details.

The currency trap. The IRS measures a euro mortgage in dollars. If the euro weakens while you owe it, paying the loan off can create a taxable US currency gain, even though you repaid exactly what you borrowed, and a currency loss on a personal home loan usually isn't deductible. Our guide to currency gains on a foreign mortgage explains it.

Illustration only. On a EUR 550,000 house (about USD 614,000), stamp duty is EUR 5,500 (about USD 6,140) [1]. On EUR 1.6 million (about USD 1.79 million), it's EUR 10,000 on the first million, EUR 10,000 on the next half-million and EUR 6,000 on the last EUR 100,000, so EUR 26,000 (about USD 29,000).

Tax when you sell

The Irish side

Ireland taxes capital gains at 33%, with a small annual exemption of EUR 1,270 per person [3]. PPR relief removes the tax entirely if the home was your main residence for the whole time you owned it. The last 12 months always count as occupied, and so do some absences, including time when your job's duties were all performed outside Ireland. If you lived there for part of the time, only that share of the gain is exempt: 11 years out of 14 means 11/14 of the gain [4].

Selling a house or apartment for more than EUR 1 million? The buyer must withhold 15% of the price unless you hand over a CGT clearance certificate (Form CG50A) before closing [7]. Irish CGT on sales in January through November is due by December 15 of that year [3].

The US side

Uncle Sam taxes your worldwide gain, in dollars:

Section 121 can cover a Dublin home. Own it and live in it as your main home for at least 24 months of the 5 years before the sale, and up to USD 250,000 of gain (USD 500,000 for most joint filers) is excluded [5]. The rules don't limit it to US homes.
The timing tests differ. PPR relief looks at your whole ownership period; Section 121 looks at the last five years. A Dublin home you lived in for years, then rented out for four, can be partly exempt in Ireland and fully taxable in the US.
The foreign tax credit. Irish CGT is an income-type tax, so on a rental sale it can go on Form 1116 against US tax on the same gain [6]. Stamp duty and Local Property Tax don't count.
Currency counts. Your dollar cost uses the exchange rate when you bought and your proceeds use the rate when you sell, so a stronger euro can create a US gain on a house that didn't go up in euros.

Your old house in Boston

The 2-of-5-years clock keeps running after you move. More than three years away, and the exclusion is usually gone, while depreciation from renting it out is taxed on sale either way. Massachusetts can tax the gain on Massachusetts property, and Ireland may tax it too if you're Irish resident when you sell, with the US-Ireland tax treaty sorting out who credits whom. Our guide to selling your US home after moving abroad walks through it.

Renting it out

The Irish side. Irish rent is taxed as income at your marginal rates, after allowable expenses such as mortgage interest, repairs, insurance and agent fees. You must register each tenancy with the Residential Tenancies Board, and Dublin's rent rules limit how much you can charge and raise. If you move away and keep renting it, Ireland wants its tax collected locally: through an Irish collection agent, or by the tenant withholding tax from the rent. Short-term letting in Dublin generally needs planning permission unless it's your own home and you stay within the limits.

The US side. Report the rent on Schedule E. A Dublin home is used predominantly outside the United States, so you must depreciate it under the Alternative Depreciation System over 30 years, not the 27.5 years you'd use for a rental in Boston [8][9]. Irish income tax on the rent can go on Form 1116.

If it's the house back home you're renting out, see our guide to rental income from a US property.

Which makes sense for whom

Staying long term. Buying in Dublin can beat renting in one of Europe's tightest rental markets. Stamp duty is low, PPR relief usually wipes out Irish tax, and Section 121 covers most US gains if you sell after living there two of the last five years.
Irish passport through a grandparent. Citizenship changes nothing about the purchase rules, but it may make Ireland your long-term base, which is when buying pays off.
Retiring in Ireland. Possible, but plan for two estate regimes: Ireland's capital acquisitions tax falls on heirs, and the US estate tax looks at the whole estate. See wills and estate planning across two countries.
Moving back in a few years. Renting in Dublin and keeping (or buying) a home stateside is usually simpler. A Dublin home you rent out after leaving brings Irish rental tax, US depreciation rules and a shrinking Section 121 window.

Want to compare notes with people who've done it? Ask in our community group for Americans in Ireland. A US expat tax preparer (or an Irish solicitor) can check your situation before you go sale agreed.
