The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Argentina and Brazil operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Argentina's top marginal rate of 35% is 7 percentage points above Brazil's 28%, making the statutory gap one of the largest variables in this comparison. Brazil uses a fixed 184-day threshold for residency; Argentina relies on a multi-factor test with no single day-count trigger.

On a $100k single-resident employment profile under each country's default schedule, Argentina produces the lower effective burden at 35.0% versus 35.5% in Brazil — a 0.5 percentage-point gap that compounds to roughly $534 of additional take-home annually. The 7-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 35% in Argentina but only 28% in Brazil. Brazil levies a social-security contribution on employment income; Argentina does not model one in the engine, so the bracket comparison here is relatively clean for Argentina. 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.

Brazil offers the 10% Foreign Investment Income (flat 10% on qualifying income) for qualifying incoming residents; Argentina has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Argentina schedule immediately. For movers who don't qualify for Brazil's 10% Foreign Investment Income, both countries revert to their default progressive schedules, where Argentina's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Argentina edges Brazil by 0.5 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the 10% Foreign Investment Income is available: eligible movers may find Brazil the stronger play once the regime replaces the default schedule.
