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
For an Irish resident who is non-domiciled:
| 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
After 3 years of Irish tax residence, a person becomes ordinarily resident.
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
Implication: 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
Irish CGT rate: 33% on gains above the annual exemption.
| 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.
Section 7 — Comparison with UK Non-Dom
| Feature | Ireland | UK (from April 2025) |
|---|---|---|
| Regime | Domicile-based remittance | 4-year FIG for new residents (domicile rules transitioning out) |
| Duration | Indefinite while non-dom | 4 years maximum FIG exemption |
| Minimum tax | None | None |
| Irish/UK source taxed in full | Yes | Yes |
| Annual exemption (CGT) | €1,270 | £3,000 |
