Most of the gap is opened by United States's Foreign Earned Income Exclusion regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Argentina taxes residents on worldwide income, while United States taxes its citizens on worldwide income regardless of residence — a structural difference that shapes how each country treats foreign-source income. Top statutory rates are close — Argentina at 35% vs United States at 37% — so the outcome turns on bracket structure, social charges, and available regimes rather than the headline rate alone. United States uses a fixed 183-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, United States produces the lower effective burden at 24.4% versus 35.0% in Argentina — a 10.6 percentage-point gap that compounds to roughly $10,638 of additional take-home annually. Argentina's uncapped social-security charge lifts its effective burden above what the bracket schedule alone would imply; United States's contributions are capped, so high earners there pay a lower marginal social rate on income above the cap. United States 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 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.

United States offers the Foreign Earned Income Exclusion (flat 0% 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 United States's Foreign Earned Income Exclusion, 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, United States edges Argentina by 10.6 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Argentina taxes residents on worldwide income, so the headline effective rate applies to total global earnings — not just locally-sourced pay.
