Ireland Non-Dom Remittance Basis: A Practical Guide

How Ireland's non-domiciled remittance basis works for resident non-doms: the tax position on foreign income and gains, remittance traps, and who it suits.

As several long-standing non-dom regimes around the world are narrowed or abolished, internationally mobile individuals are re-examining where they can live well and be taxed sensibly. Ireland is one of the jurisdictions that still operates a meaningful non-domiciled remittance basis, and it does so for individuals who become Irish tax resident without being Irish domiciled.

The proposition is straightforward in principle and nuanced in practice. An Irish-resident non-dom is generally taxed in Ireland on Irish-source income and gains in full, but on foreign income and gains only to the extent those amounts are remitted to Ireland. Money kept and used outside Ireland can, broadly, remain outside the Irish tax net.

For founders, investors and families considering a base in Europe, this can be highly attractive. But the regime rewards precision and punishes the careless. The detail of what counts as a remittance, and what does not, is where the real planning lies.

Residence and domicile: two separate tests

Irish personal tax turns on two distinct concepts, and conflating them is the most common early error.

Residence is largely a day-counting test. Broadly, you are Irish tax resident in a tax year if you spend 183 days or more in Ireland in that year, or 280 days or more across the current and preceding year combined, subject to a de minimis rule for the single year. There is also the related concept of ordinary residence, which is acquired after being resident for a run of consecutive years and which continues for a period after you leave.

Domicile is a different and stickier concept inherited from common law. It reflects your permanent home and long-term intentions, not where you happen to live this year. Most people have a domicile of origin acquired at birth, and shedding it for a domicile of choice requires genuinely severing ties and intending to remain elsewhere permanently. An individual can readily be Irish resident while remaining non-Irish domiciled, and it is that combination that unlocks the remittance basis.

How the remittance basis works

For an Irish resident, non-domiciled individual, the headline position is as follows.

Irish-source income and gains are taxable in Ireland in the normal way, regardless of where the money goes. There is no shelter for Irish earnings, Irish rental income, or gains on Irish assets.

Foreign income (for example, foreign employment income relating to duties performed outside Ireland, foreign dividends, foreign interest and foreign rents) is taxable in Ireland only to the extent it is remitted into Ireland. Foreign income that stays abroad is, broadly, outside the charge.

Foreign capital gains are likewise taxable only on remittance of the proceeds into Ireland. Gains realised on non-Irish assets and kept offshore are not taxed simply because they arose.

The practical effect is that a non-dom can fund an Irish lifestyle from clean capital or non-remitted sources while leaving foreign income and gains to accumulate outside Ireland untaxed there, provided the money genuinely stays out and is not brought in, directly or indirectly.

Remittance traps that catch people out

The word "remittance" is broader than most newcomers assume, and the traps are where good intentions go wrong.

A remittance is not only a bank transfer into an Irish account. Bringing money into Ireland in any form can be a remittance, including spending foreign income on an Irish credit or debit card, using foreign funds to settle an Irish debt, or importing assets purchased with untaxed foreign income.

Mixed funds are a persistent hazard. If foreign income and gains are blended with clean capital in a single account, a later transfer to Ireland can be treated as carrying the taxable income or gains out first, taxing what you hoped to keep clean. Disciplined account segregation, separating clean capital, foreign income and foreign gains into distinct accounts, is essential from the outset.

There are also specific anti-avoidance rules and the interaction with capital acquisitions tax (Ireland's gift and inheritance tax) and with reporting under the Common Reporting Standard to keep in view. And remember that the remittance basis affects Irish tax only. Your home country may continue to tax you, and double-tax treaties and exit rules must be considered before any move.

Practical planning before you arrive

The single most valuable step is pre-arrival planning, completed before you become Irish resident.

That typically means realising or restructuring gains before residence begins where appropriate, establishing clean segregated accounts, identifying a pool of clean capital that can be remitted to Ireland without tax, and documenting the source and character of funds so that later remittances can be traced and defended. Once you are resident and your accounts are mixed, options narrow considerably.

It also means being honest about your domicile position. If you intend to settle in Ireland permanently, you may over time acquire an Irish domicile of choice, which would end access to the remittance basis. The regime suits those whose long-term home remains genuinely elsewhere.

Who Ireland's non-dom regime suits

The remittance basis suits internationally mobile individuals with substantial foreign income or gains who want a stable, English-speaking, common-law EU base and who can comfortably fund their Irish life without remitting foreign income, or by remitting only clean capital. It suits founders who have realised offshore wealth, investors with foreign portfolios, and families relocating from a higher-tax or now-narrowing regime elsewhere.

It is less compelling for those whose income is largely Irish-source, for whom there is no foreign income to shelter, and it requires real discipline from anyone unwilling to run segregated accounts and keep records. It is also not a route to invisibility: reporting obligations apply, and the structure must be genuine.

How HPT helps

We advise non-domiciled individuals on whether the Irish remittance basis fits their circumstances and on implementing it properly: residence and domicile analysis, pre-arrival restructuring, clean-capital segregation, remittance planning, coordination with home-country exit and treaty rules, and ongoing Irish compliance. We work alongside Irish tax counsel so the position is both efficient and defensible.
