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 Greece and Ireland operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Greece at 44% vs Ireland at 40% — so the outcome turns on bracket structure, social charges, and available regimes rather than the headline rate alone.

On a $100k single-resident employment profile under each country's default schedule, Ireland produces the lower effective burden at 30.4% versus 46.5% in Greece — a 16.1 percentage-point gap that compounds to roughly $16,120 of additional take-home annually. Ireland's uncapped social-security charge lifts its effective burden above what the bracket schedule alone would imply; Greece's contributions are capped, so high earners there pay a lower marginal social rate on income above the cap. Social-security contributions also differ: Greece charges 13.9% versus 4.3% in Ireland, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone. 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: Greece's Greek Foreign Pensioner 7% (7% flat) and Ireland's Irish Non-Dom Remittance (30% flat). On headline rate alone, Greece's Greek Foreign Pensioner 7% at 7% beats the alternative at 30% — a 23-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Ireland edges Greece by 16.1 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Greece's Greek Foreign Pensioner 7% (7%) outperforms Ireland's default 30.4% effective rate — for qualifying applicants it often does.
