E-2 Investors From Ireland: Tax on the Business, the Investment and You

E-2 investors from Ireland often assume a nonimmigrant visa means nonresident for tax. It usually does not. Here is how the company, the investment and your own residence are taxed.

Quick answer

Is an E-2 investor from Ireland a US tax resident?

Usually yes, once living in the US for most of the year. E-2 is not an exempt-individual category under IRS Pub 519, so your days count under the substantial presence test, and a resident is taxed on worldwide income. If Ireland also treats you as resident, Article 4 (Residence) of the treaty breaks the tie. Your company files its own returns: Form 1120, and Form 5472 while it is foreign-owned.

Structuring the E-2 business from Ireland

The structure you choose in the US decides the filings, not the visa. A corporation files Form 1120 every year (IRS). An LLC follows Treas. Reg. section 301.7701-3: disregarded with one owner, a partnership with more, or a corporation if it elects (IRS). Foreign ownership adds Form 5472 and its US$25,000 penalty (IRS), and a new business set up by someone from Ireland generally needs a BE-13 within 45 days (BEA rule).

Putting your money in

Capital or loan? Both fund the E-2 business, but they are reported differently. Amounts the company borrows from a foreign owner, and interest on them, are reportable on Form 5472 while the company has a foreign owner (IRS). Capital stays in the company as equity. Document each transfer from Ireland so the books and the returns tell the same story.

Your own filings after the move

FBAR and Form 8938 for accounts you keep in Ireland; see FBAR and FATCA and Form 8938.
Form 5471 if you keep control of a company in Ireland: a US person controlling more than 50% of a foreign corporation is a Category 4 filer, with a US$10,000 penalty per year for not filing (IRS). See Form 5471.
Funds held in Ireland can be PFICs; see PFIC and Form 8621 for how the rules work.
Once you are a US resident you are no longer a foreign person for Form 5472, which the IRS defines as an individual who is not a citizen or resident (IRS). Whether the company still files depends on who else owns it.
Form 1040 on worldwide income every year you are resident, including income from Ireland.

Residence: when the US taxes you on everything

E-2 status does not make you an exempt individual: IRS Pub 519 limits that to foreign government-related individuals, teachers and trainees on J or Q visas, students on F, J, M or Q visas and certain athletes (IRS Pub 519). So your days in the US count under the substantial presence test in Code section 7701(b), and most E-2 investors become US tax residents in the first year they live here. That first year is usually dual-status.

If Ireland also treats you as resident, Article 4 (Residence) of the treaty is the tie-breaker; relying on it on a US return needs Form 8833 under Treas. Reg. section 301.7701(b)-7 (IRS).

For social security, the US and Ireland have an agreement in force since September 1, 1993 (SSA); a certificate of coverage can keep you in one system (Pub 519).

Taking money out before you are resident

While you still live in Ireland, dividends and interest from your US company are not reported on a US return the usual way: the company withholds, at 30% unless the treaty gives a lower rate (IRS Pub 515).

Payment to a resident of Ireland	General treaty rate (IRS Table 1)	Treaty citation
Dividends from a US corporation	15%	Article 10(2)
Interest on a loan you made to the company	0%	Article 11(1)

Rates from IRS Tax Treaty Table 1 (Rev. May 2023). The IRS notes the table is not a complete guide to eligibility; the treaty's conditions, including any limitation on benefits, must be met. Once you are a US resident these rates no longer apply to you.

Common questions

What counts as a substantial E-2 investment from Ireland?

USCIS does not set a fixed minimum. The investment must be substantial in relation to the total cost of the business, and the lower the cost, the higher the proportion expected. The enterprise may not be marginal. Your immigration lawyer advises on this.

Does an E-2 investor from Ireland pay US tax on worldwide income?

Usually yes, once resident. E-2 is not an exempt-individual category, so the substantial presence test applies, and a US resident is taxed on worldwide income from the residency starting date.

What if Ireland also treats me as resident?

Article 4 (Residence) of the treaty decides residence for treaty purposes; claiming it on a US return needs Form 8833.

Does the E-2 company file Form 5472?

A US corporation that is 25% or more foreign-owned files Form 5472 with Form 1120, and a single-member LLC files it while its owner is a foreign person. Once you are a US resident you are no longer a foreign person for this purpose.
