Income Tax Calculator Australia 2025-26

How Australian Income Tax Works in 2025-26

The Australian income tax calculator computes your total tax liability for the 2025-26 financial year (1 July 2025 to 30 June 2026) based on official ATO progressive tax brackets. Australia taxes residents on worldwide income using a marginal rate system where each portion of income is taxed at its applicable bracket rate, not your entire income at the highest rate.

For Australian residents, the 2025-26 tax brackets are: nil on the first $18,200 (tax-free threshold), 16% on $18,201 to $45,000, 30% on $45,001 to $135,000, 37% on $135,001 to $190,000, and 45% on income above $190,000. These rates were updated from 1 July 2024 under the Stage 3 tax cuts, reducing the 32.5% rate to 30% and raising the $120,000 threshold to $135,000.

Non-residents pay tax from the first dollar with no tax-free threshold: 30% on $0 to $135,000, 37% on $135,001 to $190,000, and 45% above $190,000. Working holiday makers (subclass 417/462 visa holders) pay a flat 15% on the first $45,000 and standard rates above that threshold. Last updated: April 2026, based on ATO 2025-26 published rates.

Medicare Levy and Surcharge Explained

The Medicare levy funds Australia's public healthcare system and is charged at 2% of taxable income for most taxpayers. Low-income individuals earning below approximately $26,000 receive a full exemption, with a phase-in range where a reduced levy applies. Non-residents and working holiday makers are generally exempt from the Medicare levy.

The Medicare Levy Surcharge (MLS) is an additional charge of 1% to 1.5% that applies to Australian residents who earn above $93,000 (singles) or $186,000 (families) and do not hold an appropriate level of private hospital insurance. The surcharge is tiered: 1% for $93,001 to $108,000, 1.25% for $108,001 to $144,000, and 1.5% above $144,000. This calculator applies the applicable MLS rate based on your income and insurance status.

HELP/HECS Repayment Thresholds 2025-26

If you have a Higher Education Loan Program (HELP) or HECS debt, compulsory repayments are deducted through the tax system once your repayment income exceeds $54,435 for the 2025-26 year. The repayment rate starts at 1% and increases progressively: 2% at $62,851, 2.5% at $66,621, 3% at $70,619, and continuing up to 10% for incomes above $151,201.

HELP repayments are calculated on your total repayment income, which includes taxable income, reportable fringe benefits, and net investment losses. These repayments are separate from your income tax and are collected by the ATO when you lodge your tax return. Your outstanding HELP debt is indexed annually by CPI on 1 June.

Superannuation Guarantee for 2025-26

Australian employers are required to contribute superannuation at a rate of 11.5% of ordinary time earnings for the 2025-26 financial year (increasing to 12% from 1 July 2026). This calculator shows your estimated super contribution based on your gross income and the selected rate. Super is paid on top of your salary and is not deducted from your take-home pay unless you make additional voluntary contributions through salary sacrifice arrangements.
