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.
Costa Rica uses a territorial system — only locally-sourced income enters the tax base, while Indonesia taxes residents on worldwide income — a structural difference that shapes how each country treats foreign-source income. Indonesia's top marginal rate of 35% is 10 percentage points above Costa Rica's 25%, 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, Costa Rica produces the lower effective burden at 28.3% versus 28.5% in Indonesia — a 0.2 percentage-point gap that compounds to roughly $150 of additional take-home annually. The 10-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 35% in Indonesia but only 25% in Costa Rica. Social-security contributions also differ: Costa Rica charges 10.7% versus 3.0% in Indonesia, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone. 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: Costa Rica's Costa Rica Digital Nomad Visa (0% flat) and Indonesia's Indonesia 4-Year Territoriality (0% flat). The two regime rates are nearly identical (0% vs 0%), so eligibility criteria and duration will determine which is more accessible rather than the rate itself. Indonesia's regime runs for 4 years versus 2 in Costa Rica — a longer runway worth factoring into a multi-year relocation plan.
For a digital nomad or remote worker on a $100k income, Costa Rica edges Indonesia by 0.2 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Indonesia's Indonesia 4-Year Territoriality (0%) outperforms Costa Rica's default 28.3% effective rate — for qualifying applicants it often does. Costa Rica's territorial system means foreign-source income stays off the resident tax base entirely — a structural advantage for nomads paid by overseas clients that no rate comparison fully captures.
