The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Australia taxes residents on worldwide income, while Georgia uses a territorial system — only locally-sourced income enters the tax base — a structural difference that shapes how each country treats foreign-source income. Australia's top marginal rate of 45% is 25 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 26.7% in Australia — a 4.7 percentage-point gap that compounds to roughly $4,722 of additional take-home annually. The 25-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 45% in Australia but only 20% in Georgia.

Georgia offers the Small Business Status (1% Turnover) (flat 1% on qualifying income) for qualifying incoming residents; Australia has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Australia schedule immediately. For movers who don't qualify for Georgia's Small Business Status (1% Turnover), both countries revert to their default progressive schedules, where Australia's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Georgia edges Australia by 4.7 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. 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.
