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.
Italy 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. Italy's top marginal rate of 43% is 6 percentage points above United States's 37%, 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 39.7% in Italy — a 15.4 percentage-point gap that compounds to roughly $15,377 of additional take-home annually. The 6-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 43% in Italy but only 37% in United States. 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: Italy's Foreign Pensioner 7% (7% flat) and United States's Foreign Earned Income Exclusion (0% flat). On headline rate alone, United States's Foreign Earned Income Exclusion at 0% beats the alternative at 7% — a 7-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, United States edges Italy by 15.4 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Italy's Foreign Pensioner 7% (7%) outperforms United States's default 24.4% effective rate — for qualifying applicants it often does. Italy taxes residents on worldwide income, so the headline effective rate applies to total global earnings — not just locally-sourced pay.
