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 Estonia and Ireland operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Ireland's top marginal rate of 40% is 18 percentage points above Estonia's 22%, 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, Estonia produces the lower effective burden at 21.6% versus 30.4% in Ireland — a 8.8 percentage-point gap that compounds to roughly $8,771 of additional take-home annually. The 18-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 40% in Ireland but only 22% in Estonia. 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.

Ireland offers the Irish Non-Dom Remittance (flat 30% on qualifying income) for qualifying incoming residents; Estonia has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Estonia schedule immediately. For movers who don't qualify for Ireland's Irish Non-Dom Remittance, both countries revert to their default progressive schedules, where Estonia's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Estonia edges Ireland by 8.8 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Irish Non-Dom Remittance is available: eligible movers may find Ireland the stronger play once the regime replaces the default schedule.
