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.
Panama uses a territorial system — only locally-sourced income enters the tax base, while United States taxes its citizens on worldwide income regardless of residence — a structural difference that shapes how each country treats foreign-source income. United States's top marginal rate of 37% is 12 percentage points above Panama'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, United States produces the lower effective burden at 24.4% versus 28.1% in Panama — a 3.7 percentage-point gap that compounds to roughly $3,738 of additional take-home annually. The 12-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 37% in United States but only 25% in Panama.

United States offers the Foreign Earned Income Exclusion (flat 0% on qualifying income) for qualifying incoming residents; Panama has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Panama 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 Panama's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, United States edges Panama by 3.7 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Panama'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.
