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 Mexico operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Indonesia at 35% vs Mexico at 35% — 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, Indonesia produces the lower effective burden at 28.5% versus 30.4% in Mexico — a 1.9 percentage-point gap that compounds to roughly $1,883 of additional take-home annually. 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 Mexico's RESICO (Simplified Regime) (2% flat). The two regime rates are nearly identical (0% vs 2%), 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, Indonesia edges Mexico by 1.9 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Mexico's RESICO (Simplified Regime) (2%) outperforms Indonesia's default 28.5% effective rate — for qualifying applicants it often does.
