Most of the gap is opened by Italy's Regime Impatriati regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Australia and Italy operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Australia at 45% vs Italy at 43% — so the outcome turns on bracket structure, social charges, and available regimes rather than the headline rate alone.

On a $100k single-resident employment profile under each country's default schedule, Australia produces the lower effective burden at 26.7% versus 39.7% in Italy — a 13 percentage-point gap that compounds to roughly $13,017 of additional take-home annually. Australia's uncapped social-security charge lifts its effective burden above what the bracket schedule alone would imply; Italy's contributions are capped, so high earners there pay a lower marginal social rate on income above the cap. Social-security contributions also differ: Italy charges 9.2% versus 2.0% in Australia, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone. 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.

Italy offers the Foreign Pensioner 7% (flat 7% 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. The Foreign Pensioner 7% runs for up to 10 years from first qualification, giving Italy a meaningful medium-term advantage for eligible movers who plan to stay. Eligibility requires 5+ years of prior non-residency in Italy — the regime is unavailable to returning nationals and anyone who has held Italy tax residency recently. For movers who don't qualify for Italy's Foreign Pensioner 7%, 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, Australia edges Italy by 13 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Foreign Pensioner 7% is available: eligible movers may find Italy the stronger play once the regime replaces the default schedule.
