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 Northern Territory 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.
The Northern Territory has the smallest population of any Australian state or territory, with Darwin as its capital and largest city. The NT's tropical climate, remote geography, and resources-based economy (including mining and increasingly liquefied natural gas processing) create a distinct economic profile compared to the southern states. Income tax remains entirely federal, identical to the rest of the country. The NT government offers various incentive schemes to attract residents and workers to the territory, given its smaller population base and the challenges of attracting skilled labour to a remote, tropical part of the country, though these incentives operate alongside (not instead of) the standard federal income tax system.
| 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.
