Most of the gap is opened by Costa Rica's Costa Rica Digital Nomad Visa regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Brazil taxes residents on worldwide income, while Costa Rica uses a territorial system — only locally-sourced income enters the tax base — a structural difference that shapes how each country treats foreign-source income. Top statutory rates are close — Brazil at 28% vs Costa Rica at 25% — 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, Costa Rica produces the lower effective burden at 28.3% versus 35.5% in Brazil — a 7.2 percentage-point gap that compounds to roughly $7,197 of additional take-home annually. 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: Brazil's 10% Foreign Investment Income (10% flat) and Costa Rica's Costa Rica Digital Nomad Visa (0% flat). On headline rate alone, Costa Rica's Costa Rica Digital Nomad Visa at 0% beats the alternative at 10% — a 10-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Costa Rica edges Brazil by 7.2 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Brazil's 10% Foreign Investment Income (10%) 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.
