Most of the gap is opened by Indonesia's Indonesia 4-Year Territoriality regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Indonesia 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 5 percentage points above Indonesia's 35%, 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, Indonesia produces the lower effective burden at 28.5% versus 30.4% in Ireland — a 1.9 percentage-point gap that compounds to roughly $1,874 of additional take-home annually. The 5-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 35% in Indonesia. The narrow effective-rate gap means the decision between the two countries is unlikely to rest on the default schedule alone — regime availability, cost of living, and social-security treatment will be the tiebreakers.

Both countries offer dedicated regimes for incoming professionals: Indonesia's Indonesia 4-Year Territoriality (0% flat) and Ireland's Irish Non-Dom Remittance (30% flat). On headline rate alone, Indonesia's Indonesia 4-Year Territoriality at 0% beats the alternative at 30% — a 30-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Indonesia edges Ireland by 1.9 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
