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.
Estonia 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. United States's top marginal rate of 37% is 15 percentage points above Estonia's 22%, 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, Estonia produces the lower effective burden at 21.6% versus 24.4% in United States — a 2.8 percentage-point gap that compounds to roughly $2,771 of additional take-home annually. The 15-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 22% in Estonia. Social-security contributions also differ: United States charges 7.6% versus 1.6% in Estonia, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone.

United States offers the Foreign Earned Income Exclusion (flat 0% on qualifying income) for qualifying incoming residents; Estonia has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Estonia 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 Estonia's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Estonia edges United States by 2.8 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Foreign Earned Income Exclusion is available: eligible movers may find United States the stronger play once the regime replaces the default schedule. Estonia taxes residents on worldwide income, so the headline effective rate applies to total global earnings — not just locally-sourced pay.
