Do Americans need to file US tax returns while living in Ireland?

If you’re an American living in Ireland, remember that your tax obligations back in the US are still required. All US citizens and green card holders must file a US tax return annually if their income meets the minimum threshold required by the IRS, regardless of their tax residency in Ireland.

Even if you’re an Irish citizen living in Ireland, you must file a US tax return if you hold US citizenship or a Green Card.

How does the US handle dual taxation?

The US has a tax treaty with Ireland designed to prevent dual taxation, allowing you to use benefits like the Foreign Tax Credit (FTC) and the Foreign Earned Income Exclusion (FEIE) to lower your tax burden.

Do I need to file US tax returns if I’ve never lived in the United States?

Yes, your physical presence in the US does not impact your filing requirements. However, possessing US citizenship alone makes you liable to file US tax returns, regardless of having never lived in the US.

How do you establish tax residency in Ireland?

In Ireland, you are considered a tax resident if you spend 183 days or more in the country during a tax year or 280 days across two consecutive tax years.

How do the tax systems differ?

While the US practices worldwide taxation, Ireland operates on a residence-based system, taxing individuals based on residency status. Both countries share a similar tax year, from January 1 to December 31.

What about tax filing statuses and rates in Ireland and the US?

The US tax system offers multiple filing statuses with varying standard deductions and rates. Ireland provides fewer options, with tax rates split into two bands: 20% and 40%.

How do I file my US tax return?

Gather all your financial documents, including income earned, taxes paid in Ireland, and any relevant statements from pensions and investments. Having your Irish tax return on hand is a good place to start. 

Consider using a US tax professional who works with Americans living in Ireland, such as Expat Tax Online.

When are US tax returns due for those living in Ireland?

Expats automatically receive a filing extension until June 15, but any taxes owed are still due by April 15. Further extensions until October 15 can be requested by filing Form 4868.

How does Ireland handle retirement and social security?

Contributions to Irish Social Security (PRSI) provide similar benefits to US Social Security and are covered under a Totalization Agreement to prevent double taxation of these contributions.
