Australian personal income tax reform 2026

For the 2026–2027 Australian financial year, the highest marginal tax bracket threshold applies to taxable income exceeding $190,000 Verified Answer #1.

2026–27 Resident Tax Rates

The Australian Taxation Office (ATO) has established the following progressive brackets for resident individuals Verified Answer #2:

Additional Levies and Surcharges

The total effective tax rate is influenced by several additional components beyond the base progressive rates Verified Answer #1. A mandatory Medicare Levy of 2% is applied to taxable income for most taxpayers Verified Answer #2. For income exceeding $190,000, the combination of the 45% marginal rate and the 2% Medicare Levy results in a combined marginal rate of 47% on each additional dollar earned Verified Answer #2.

High-income earners without private hospital cover may also be subject to the Medicare Levy Surcharge (MLS), which ranges from 1.0% to 1.5% Verified Answer #1. Unlike progressive brackets, the MLS applies to the entire income for MLS purposes once a specific threshold is crossed, creating a "cliff" effect where a small increase in income can trigger a large tax liability Verified Answer #1.

Standard Deduction

Effective 1 July 2026, eligible taxpayers can claim a $1,000 standard deduction for work-related expenses without providing receipts Verified Answer #1. This deduction reduces taxable income, which is the primary component used to calculate income for Medicare Levy Surcharge purposes Verified Answer #1. By reducing taxable income, the $1,000 deduction may allow some taxpayers to drop into a lower MLS tier or avoid the surcharge entirely, potentially resulting in tax savings that exceed the base value of the deduction itself Verified Answer #1.
