Section 2 — Who is Non-Dom in Ireland?

Domicile in Ireland follows general law (not tax law):

• Domicile of origin: derived from father's domicile at birth
• Domicile of choice: acquired by residing in a country with indefinite intent to remain

A foreign national living in Ireland who was born outside Ireland typically retains their foreign domicile of origin unless they form a definite intention to live in Ireland permanently and indefinitely.

Residency: Separate from domicile. An individual is ordinarily resident in Ireland after 3 consecutive years of Irish tax residence. "Ordinary residence" affects how long you remain taxable after departing Ireland.

Section 3 — Remittance Basis: What Is Taxed

Remittance Basis: What Is Taxed

Income/Gain type	Tax treatment
Income arising in Ireland	Taxed in full — Irish rates
Employment income from Irish employer	Taxed in full
Foreign income remitted to Ireland	Taxed at Irish rates
Foreign income NOT remitted to Ireland	Not taxed in Ireland
Capital gains on Irish assets	33% — taxed regardless
Capital gains on foreign assets, remitted	Taxed at 33%
Capital gains on foreign assets, NOT remitted	Not taxed

• Remittance — broadly interpreted — includes bringing money/assets to Ireland, using foreign income/gains to pay Irish debts, or acquiring property in Ireland with foreign funds.

Section 4 — Clean Capital

Funds accumulated before becoming Irish tax resident are not remittances when brought to Ireland. These are "clean capital." Maintaining separate accounts for pre-Irish-residence capital vs post-residence income is strongly recommended.

Section 5 — Ordinary Residence: The Trap

• Ordinary residence threshold — After 3 years of Irish tax residence, a person becomes ordinarily resident.
• Worldwide income taxable after departure — An ordinarily resident individual who leaves Ireland remains taxable on their worldwide income (not just Irish-source) for 3 years after departure — except: Foreign employment income (if duties performed wholly outside Ireland); Certain foreign-source income that is not remitted

Moving to Ireland and then leaving after a few years doesn't immediately terminate Irish tax obligations. This is similar to the UK's rule but differently structured.

Section 6 — CGT: 33% on Irish Assets

• Effective CGT rate for companies — 33% percent (Section 28 TCA)

CGT rates and amounts

Item	Rate/Amount
CGT rate	33%
Annual exemption (individual)	€1,270
Entrepreneur Relief	10% on qualifying business disposals (up to €1M lifetime)

• Irish assets — Irish shares, Irish property, Irish business goodwill. A non-dom individual pays 33% CGT on gains from Irish assets regardless of domicile status.

Working paper only. Irish domicile determination is fact-specific and can have significant estate tax implications in addition to income tax. Engage a qualified Irish tax adviser.
