The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Australia and France 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 France at 45% — 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 45.7% in France — a 19 percentage-point gap that compounds to roughly $18,978 of additional take-home annually. Social-security contributions also differ: France charges 22.0% 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.

France offers the Régime des Impatriés (Art 155B) (flat 30% 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 Régime des Impatriés (Art 155B) runs for up to 8 years from first qualification, giving France a meaningful medium-term advantage for eligible movers who plan to stay. Eligibility requires 5+ years of prior non-residency in France — the regime is unavailable to returning nationals and anyone who has held France tax residency recently. For movers who don't qualify for France's Régime des Impatriés (Art 155B), 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 France by 19 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Régime des Impatriés (Art 155B) is available: eligible movers may find France the stronger play once the regime replaces the default schedule.
