Australia Income Tax Guide (2026-27)

The 2026-27 Tax Brackets

Australia uses a progressive income tax system, where each portion of your income is taxed at the rate for its bracket. For the 2026-27 financial year (1 July 2025 to 30 June 2026), the resident rates are: 0% on income up to $18,200 (the tax-free threshold); 16% on income from $18,201 to $45,000; 30% from $45,001 to $135,000; 37% from $135,001 to $190,000; and 45% on income above $190,000. These are the brackets introduced by the Stage 3 tax cuts (effective 1 July 2024), which lowered the second bracket to 16% and the third to 30% and raised thresholds. A worked example: on an $80,000 income you pay nothing on the first $18,200, 16% on the next $26,800 (to $45,000) which is $4,288, and 30% on the remaining $35,000 which is $10,500 — a total income tax of $14,788 before the Medicare levy. Because the system is marginal, a pay rise pushing you into a higher bracket only taxes the portion above the threshold at the higher rate, so you're never worse off overall. A further legislated change reduces the lowest bracket rate to 15% from 1 July 2026 and 14% from 1 July 2027. This calculator uses the 2026-27 rates; check the ATO for current figures.

The Medicare Levy

On top of income tax, most Australian residents pay the Medicare levy, which funds the public healthcare system. The standard Medicare levy is 2% of your taxable income, calculated separately from and in addition to your income tax — so it's easy to forget when estimating tax, but it meaningfully increases your total. This calculator can include it. Low-income earners may pay a reduced levy or be exempt entirely, depending on income thresholds that are adjusted each year. Separately, higher earners who don't have an appropriate level of private hospital insurance may also pay the Medicare Levy Surcharge (an additional 1% to 1.5% depending on income) — this is designed to encourage take-up of private health cover and is separate from the standard 2% levy. The surcharge isn't included in this calculator's standard estimate, so high earners without private cover should factor it in separately. For most working residents, the practical position is income tax plus the 2% Medicare levy, which this calculator combines to show your total tax and take-home pay. The levy and surcharge rules have income thresholds and family adjustments, so check the ATO for your specific situation.

Other Factors in Your Take-Home Pay

Several things beyond income tax and the Medicare levy affect what you actually take home. Superannuation: your employer must pay the Superannuation Guarantee (12% of your ordinary earnings from 1 July 2025) into your super fund — this is on top of your salary (for most employees) rather than deducted from it, building your retirement savings, though salary packages quoted as 'including super' work differently. HECS/HELP debt: if you have a student loan (HECS-HELP), compulsory repayments are deducted through the tax system once your income exceeds the threshold, at a rate that rises with income — this reduces take-home pay and isn't included in this calculator's basic estimate. Tax offsets: the Low Income Tax Offset (LITO) reduces tax for lower earners, and seniors and pensioners may get additional offsets — these can reduce your actual tax below the bracket figure. Salary sacrifice: arrangements like sacrificing salary into super or other benefits reduce your taxable income. PAYG withholding: your employer withholds tax from each pay based on ATO tables, and you reconcile the exact amount when you lodge your annual return (due 31 October if self-lodging), receiving a refund or bill for any difference. This calculator gives the core income tax plus Medicare levy; for an exact take-home figure including HECS, offsets, and super arrangements, use the ATO's tools or a detailed pay calculator.

Lodging and Planning

Understanding the system helps with planning and compliance. The Australian financial year runs 1 July to 30 June, and individual tax returns are generally due by 31 October if you lodge yourself, or later if you use a registered tax agent. Throughout the year, your employer withholds PAYG tax from your pay, and at year-end you lodge a return to reconcile — claiming deductions (work-related expenses, donations, and so on) that reduce your taxable income and may generate a refund. Keeping records of deductible expenses for at least five years is important, as the ATO can review returns. Deductions worth knowing about include work-related expenses, self-education costs, and donations to registered charities. For tax planning, salary sacrificing into superannuation can be tax-effective (super contributions are taxed at a concessional rate), and timing deductible expenses or income can matter near year-end. Higher earners should be aware of Division 293 tax (an extra 15% on concessional super contributions above an income threshold) and the Medicare Levy Surcharge if without private health cover. This calculator estimates your income tax and Medicare levy for 2026-27 to give you a clear core figure; for deductions, offsets, HECS, super strategy, and your exact position, the ATO's resources and a registered tax agent provide official, personalised guidance. These figures are estimates for general information only.
