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.
Georgia 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 17 percentage points above Georgia's 20%, 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, Georgia produces the lower effective burden at 22.0% versus 24.4% in United States — a 2.4 percentage-point gap that compounds to roughly $2,362 of additional take-home annually. The 17-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 20% in Georgia. Social-security contributions also differ: United States charges 7.6% versus 2.0% in Georgia, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone.

Both countries offer dedicated regimes for incoming professionals: Georgia's Small Business Status (1% Turnover) (1% flat) and United States's Foreign Earned Income Exclusion (0% flat). The two regime rates are nearly identical (1% vs 0%), so eligibility criteria and duration will determine which is more accessible rather than the rate itself.
For a digital nomad or remote worker on a $100k income, Georgia edges United States by 2.4 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether United States's Foreign Earned Income Exclusion (0%) outperforms Georgia's default 22.0% effective rate — for qualifying applicants it often does. Georgia'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.
