Ireland vs Spain Tax in 2026: Which One Actually Costs You More?

For employees: the same salary, both systems

A single employee, no dependants, on €60,000 gross.

Effective rate: 25.1% in Ireland, 29.7% in Spain. The Irish employee is €2,741 a year better off — a real gap, but a fraction of what most people expect in either direction.

The ceiling that flips the result

One difference explains the whole shape of the table.

Spanish employee contributions are 6.5% of salary — 4.7% for general contingencies, 1.55% unemployment, 0.1% training, and 0.15% for the intergenerational equity mechanism. But they are charged on a base that stops at €5,101.20 a month, or €61,214.40 a year. Earn more and you pay nothing extra.

Ireland has no such ceiling. PRSI applies to the whole salary at 4.2%, and USC not only continues but rises to 8% above €70,044.

So at €100,000, the Spanish employee pays €3,978.94 in contributions — almost exactly what they paid at €61,214. The Irish employee pays €4,237.50 in PRSI plus €4,030.62 in USC. That's the entire crossover: Spain's headline income tax is heavier, but Ireland keeps charging social contributions long after Spain has stopped.

Two consequences worth holding on to. Below the ceiling, Ireland wins comfortably — Irish credits are flat-rate and generous at the bottom, which is why €30,000 is nearly ten points apart. Above it, Spain catches up fast, and in a low-tax region it overtakes.

The variable Ireland doesn't have

Spanish income tax is split roughly in half: a state scale that applies everywhere, and an autonomic scale set by your region. Madrid's tops out at 20.5%. Catalonia's scale runs to 25.5% at the top. Madrid also sets its own personal minimum — €5,956.65 against the state's €5,550 — which shaves a little more off the bill.

The practical effect is that the same salary produces a materially different net depending on which side of a regional border you live on. Moving from Madrid to Barcelona is a tax event in a way that moving from Dublin to Galway simply is not.

Ireland has no regional income tax at all. No county rate, no city surcharge, no local scale. Whatever else you think of the Irish system, your address inside the country does not change your tax bill — and that makes Irish figures portable in a way Spanish ones are not. Treat any single "Spain" number, including ours, as a regional example rather than a national fact.

What the table doesn't show

Three things that matter and appear in no comparison table.

In Ireland, nobody claims your reliefs for you. Rent credit, medical expenses, remote working relief, flat rate expenses — every one requires you to file. You have four years, and most people never do. A Spaniard used to the borrador arriving pre-filled from the Agencia Tributaria will find the Irish system leaves far more on the table, and leaves it there quietly. See the top Irish tax deductions you could be missing.

Investment income is taxed very differently. Spain applies a separate savings scale — 19% on the first €6,000, rising through 21%, 23% and 27% to 30% above €300,000. Ireland charges a flat 33% on capital gains with a €1,270 annual exemption. For most ordinary investors, Spain is the cheaper place to realise a gain, and the gap is widest on smaller disposals. See capital gains tax in Ireland.

Spain has a much broader regime for new arrivals than Ireland. The régimen de impatriados — widely called the Beckham law — taxes employment income at a flat 24% up to €600,000, and 47% above that, for the year of the move plus the following five. It requires that you were not resident in Spain in the five tax periods before the move. For a high earner relocating to Spain, this rewrites the entire comparison above; for anyone below roughly €60,000 it usually does not help at all, because the ordinary scale is already gentler. Ireland's closest equivalent, SARP, is far narrower: it applies only to executives assigned here by their employer, and exempts 30% of earnings above €125,000 from income tax.

For companies and the self-employed

For established companies, Ireland wins clearly. Spain's general rate is 25%, twice Ireland's trading rate. Spain has been stepping its small-company rates down — micro companies, meaning turnover under €1 million, pay 19% on the first €50,000 of taxable profit and 21% above it in 2026, and that reduction continues in later years — but the starting point is still well above 12.5%.

The usual Irish caveats apply. The 12.5% is for trading income only; rental and investment profits are taxed at 25%. And an Irish company needs at least one EEA-resident director — which Spanish residents satisfy.

For the newly self-employed, Spain has something Ireland doesn't. A new autónomo pays a flat €80 a month in social security for the first twelve months, extendable by another twelve if earnings stay below the minimum wage. After that the cuota is set by income band, reaching €605 a month and above at the top of the scale. An Irish sole trader pays PRSI at the same 4.2% as an employee — cheaper than a Spanish autónomo at mid and high incomes, but with nothing resembling that first-year flat rate. If you're starting out, Spain is materially cheaper for a year or two. If you're established and profitable, Ireland is cheaper indefinitely.

If you're moving between the two

Coming to Ireland from Spain. Your first year is usually your largest refund. Irish credits are spread across twelve months, so arriving mid-year means a full year's credits meet a part year's earnings. Split Year Treatment protects that by excluding pre-arrival employment income. And most new arrivals spend their first months on emergency tax without realising it. The country-specific detail is in tax for Spanish workers in Ireland.

Going the other way. Whether the Beckham regime is available to you is the question that matters most, and it turns on those five prior years of non-residence — which a spell in Ireland may well have supplied. On the Irish side, your departure year is usually a refund, and four years remain open behind you. 2022 closes permanently on 31 December 2026. See leaving Ireland and the refund you might be owed.

Ireland and Spain have had a double taxation convention since it was signed in Madrid on 10 February 1994, so the same income shouldn't be taxed twice — but relief is claimed and evidenced, not applied automatically. You can find the text on Revenue's page for the Ireland–Spain treaty. Note too that after three consecutive years of Irish residence you become ordinarily resident, which brings disposals of assets anywhere in the world within Irish CGT, and continues for three years after you stop being resident. The framework is in moving to Ireland: how cross-border taxes work, and the fundamentals are in the complete guide.
