Most of the gap is opened by Ireland's Irish Non-Dom Remittance regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Spain and Ireland operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Spain's top marginal rate of 47% is 7 percentage points above Ireland's 40%, making the statutory gap one of the largest variables in this comparison.

On a $100k single-resident employment profile under each country's default schedule, Ireland produces the lower effective burden at 30.4% versus 38.7% in Spain — a 8.4 percentage-point gap that compounds to roughly $8,384 of additional take-home annually. The 7-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 47% in Spain but only 40% in Ireland. The gap widens at higher incomes as marginal rates diverge further; remote workers earning above $150k or $200k should run the full engine scenario with their actual figures for a more precise read.

Both countries offer dedicated regimes for incoming professionals: Spain's Beckham Law and Ireland's Irish Non-Dom Remittance (30% flat).
For a digital nomad or remote worker on a $100k income, Ireland edges Spain by 8.4 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
