About Canberra and Australian Capital Territory
The ACT is Australia's smallest state/territory by population but has the highest median income — largely due to the concentration of federal public-sector employment in Canberra.
What about Australian Capital Territory state-level taxes?
- Payroll tax: ACT payroll tax is 6.85% above $2M wages (the highest threshold in the country).
- Stamp duty: ACT charges stamp duty (called "Conveyance Duty") with progressive rates and first-home buyer concessions.
- Land tax: applies to investment property holdings above the state threshold.
None of these affect your fortnightly paycheck.
Australian income tax (FY 2025-26)
Australia has a single national income tax — no state income tax. Stage 3 cuts have been in effect since 1 July 2024 and continue through FY 2025-26. The system is progressive with a tax-free threshold of $18,200.
| Taxable income | Rate |
|---|---|
| $0 – $18,200 | 0% (tax-free) |
| $18,201 – $45,000 | 16% |
| $45,001 – $135,000 | 30% |
| $135,001 – $190,000 | 37% |
| $190,001+ | 45% |
Australia has no joint filing — each spouse files their own return. A Low Income Tax Offset of up to $700 reduces tax for incomes under $66,667.
Medicare Levy + Medicare Levy Surcharge
The Medicare Levy is a flat 2% of taxable income for most residents (with a low-income exemption around $27,000). On top of that, the Medicare Levy Surcharge (MLS) applies to higher earners who don't hold private hospital cover:
- Singles $101,001–$118,000: 1.0%
- Singles $118,001–$144,000: 1.25%
- Singles $144,001+: 1.5%
- Family thresholds: roughly double the single thresholds, plus $1,500 per dependent after the first
Superannuation Guarantee (12%)
Employers must contribute 12% of your ordinary time earnings to your super fund (FY 2025-26 is the first year at 12% — the final step of the legislated increase). Super sits on top of your salary in most awards — though some employment contracts quote a "total package" that bundles super into the headline number.
You can voluntarily redirect pre-tax salary into super via salary sacrifice. Sacrificed amounts reduce your taxable income — saving tax at your marginal rate. The annual concessional cap for FY 2025-26 is $30,000 (including the SG).
HECS-HELP — new marginal system (from 1 July 2025)
HECS-HELP repayments switched to a marginal system starting FY 2025-26. Previously the entire income was taxed at a single bracket rate; now repayments apply only to the portion above the threshold, with cascading rates:
| Repayment income | Repayment |
|---|---|
| $0 – $67,000 | $0 |
| $67,001 – $125,000 | 15c per $1 over $67,000 |
| $125,001 – $179,285 | $8,700 + 17c per $1 over $125,000 |
| $179,286+ | 10% of total repayment income |
This change saves most borrowers money — particularly those who were just over the previous $54,435 threshold.
