Irish CGT and your move to Dubai: what stays taxable

Does moving to Dubai mean you stop paying Irish CGT?
For many gains, yes, eventually. But the transition is not immediate, and two categories of asset never fully leave the Irish net.
The first is straightforward: Irish land and buildings remain subject to Irish CGT for non-residents, permanently. There is no residency workaround for property sitting on Irish soil. If you own a rental property in Cork or a site in Galway, the 33% rate applies to any gain whenever you sell, whether you’re living in Ranelagh or Ras Al Khaimah.
The second is more nuanced and catches far more people off guard.
What is the ordinary-residence tail?
Irish tax residency is determined by day counts: 183 days in the tax year, or 280 days combined across the current and preceding year (though that second test doesn’t apply if either year had 30 days or fewer in Ireland). Spend enough time away and you stop being resident.
Ordinary residence is different. It arrives after three consecutive years of being tax resident in Ireland and it doesn’t disappear the moment you land in Dubai. You remain ordinarily resident until you’ve completed three consecutive tax years of non-residence.
During that tail, Ireland retains the right to tax some worldwide income and gains. For capital gains specifically, assets that aren’t Irish land or buildings can still fall within the Irish net while you’re ordinarily resident, the exception that applies to employment and trade income exercised wholly abroad doesn’t carry across to CGT in the same way.
If you’re planning a significant disposal, shares in a company you’ve built, a large investment portfolio, crypto holdings that have appreciated, and you’ve been resident in Ireland for years, the timing of that disposal relative to your departure date and your ordinary-residence clock is a material financial question.
You can map out where you’d stand using the residency and three-year tail calculator.
Which assets are most at risk during the tail?
| Asset type | Non-resident but not yet ordinarily resident gone | Ordinarily resident (tail active) |
|---|---|---|
| Irish land and buildings | Irish CGT applies | Irish CGT applies |
| Shares in Irish company | Potentially in scope | In scope |
| Shares in non-Irish company | Generally outside scope | Potentially in scope |
| Irish business interest | Potentially in scope | In scope |
| UAE or other foreign property | Generally outside scope | Potentially in scope |
This table gives a broad shape, not a legal opinion. The actual position depends on asset type, structure, treaty interaction, and personal facts. The point is that the tail is real and affects a wider range of assets than most people assume when they first hear it described.
What about split-year relief in the year you leave?
Split-year relief exists for Irish tax purposes in the year of departure, but it applies to employment income, not capital gains. If you’re selling an asset in the same year you leave, the CGT position is determined by your residency and ordinary-residence status at the time of disposal, not by the split-year rules. Sequencing matters: a disposal before departure sits in a different position to one made after you’ve established UAE residency.
The UAE side of the equation
The UAE levies no personal income tax and no capital gains tax on individuals. There is nothing on the Dubai or broader UAE side to offset against an Irish CGT liability because there is no liability to offset. The Ireland–UAE double taxation agreement exists, but its practical relevance on CGT is limited for this reason.
Corporate profits above AED 375,000 are subject to UAE corporation tax at 9%, but that’s a business-level charge, not a personal CGT equivalent.
For a broader picture of how the Irish and UAE tax systems interact across income and gains, the Ireland vs Dubai take-home pay calculator gives a useful starting point.
The common mistake: selling after you’ve moved, before the tail clears
The scenario that creates the most expensive surprises is a founder who moves to Dubai, establishes residency, and assumes Irish tax is behind them, then disposes of their company shareholding two years later while still ordinarily resident. The gain can be larger than expected (businesses often grow after a move) and the ordinary-residence tail is still active.
Getting the sequencing right, departure date, disposal date, day counts, ordinary-residence clock, is not something to reconstruct after a transaction has completed. The decisions are straightforward once they’re mapped out properly; it’s the assumptions that create the problems.
