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 Ireland and Netherlands operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Netherlands's top marginal rate of 50% is 9 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 34.1% in Netherlands — a 3.8 percentage-point gap that compounds to roughly $3,762 of additional take-home annually. The 9-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 50% in Netherlands but only 40% in Ireland. Ireland levies a social-security contribution on employment income; Netherlands does not model one in the engine, so the bracket comparison here is relatively clean for Netherlands.

Both countries offer dedicated regimes for incoming professionals: Ireland's Irish Non-Dom Remittance (30% flat) and Netherlands's 30% Ruling (Expat Scheme) (30% flat). The two regime rates are nearly identical (30% vs 30%), so eligibility criteria and duration will determine which is more accessible rather than the rate itself.
For a digital nomad or remote worker on a $100k income, Ireland edges Netherlands by 3.8 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Netherlands's 30% Ruling (Expat Scheme) (30%) outperforms Ireland's default 30.4% effective rate — for qualifying applicants it often does.
