No. Unlike the US, Canada, or even the UK's devolved system, Australian income tax is set entirely at the federal level — there is no separate South Australia state income tax. Every Australian resident pays the exact same income tax brackets and Medicare Levy regardless of which state or territory they live in. What differs by state is payroll tax (which employers pay, not employees directly), stamp duty, and land tax — none of which affect your personal income tax return.
South Australia is known for its world-class wine regions, including the Barossa Valley and McLaren Vale, alongside a manufacturing and defence industry base centred on Adelaide, the state capital. Adelaide consistently ranks as one of the more affordable Australian capital cities for housing, making it an increasingly popular choice for people seeking a major-city lifestyle without Sydney or Melbourne's price tag. Income tax remains entirely federal, identical nationwide. South Australia's economy has diversified in recent years beyond traditional manufacturing into renewable energy, defence technology, and space industry initiatives centred in Adelaide.
| Taxable income | Tax rate |
|---|---|
| $0 – $18,200 | Nil |
| $18,201 – $45,000 | 16c for each $1 over $18,200 |
| $45,001 – $135,000 | $4,288 + 30c for each $1 over $45,000 |
| $135,001 – $190,000 | $31,288 + 37c for each $1 over $135,000 |
| Over $190,000 | $51,638 + 45c for each $1 over $190,000 |
Tax on $80,000: $4,288 + 30% × ($80,000 − $45,000) = $14,788. Medicare Levy: $80,000 × 2% = $1,600. Take-home: approximately $63,612 per year — identical to the same salary anywhere else in Australia, since income tax doesn't vary by state.
