ATO Tax Basics for New Residents in Australia (2026)

Australia's tax system is progressive and residency-based, which means the single biggest factor determining how much tax you pay isn't your visa type — it's whether the ATO considers you a resident for tax purposes. Here's what every newcomer needs to understand for the 2025–26 and 2026–27 financial years.

Australia's Tax Year Is Different From the Calendar Year

The Australian financial year runs from 1 July to 30 June. So the "2025–26" tax year covers 1 July 2025 to 30 June 2026, and returns for that year are generally due by 31 October 2026 if you lodge yourself, or later (up to 15 May 2027) if you use a registered tax agent.

Tax Residency: Why It Changes Everything

The ATO uses several tests to determine residency, and satisfying any one of them generally makes you a resident for tax purposes:

• Resides test: You live in Australia permanently or for a significant, settled period.
• Domicile test: Your permanent home (domicile) is in Australia.
• 183-day test: You spend 183 or more days in Australia during the tax year.
• Commonwealth superannuation test: A special rule for certain government employees.

If you're not sure of your status, check the ATO's official residency guide or speak to a tax agent — it's worth confirming, because the tax difference between residents and non-residents is substantial.

Expert Insight

Determining residency for tax purposes is distinct from your visa status under the Department of Home Affairs. Many temporary visa holders working in Australia on a settled basis meet the "resides test" within months of arrival, making them eligible for resident tax brackets and the tax-free threshold.

2026–27 Tax Brackets for Residents

• 0% on income up to $18,200 (the tax-free threshold).
• 15% on $18,201–$45,000 (reduced from 16% starting 1 July 2026).
• 30% on $45,001–$135,000.
• 37% on $135,001–$190,000.
• 45% on income above $190,000.

Plus a 2% Medicare levy on top for most residents.

Tax Brackets for Foreign Residents (Non-Residents)

If you don't meet the residency tests, you're taxed differently — and less favorably:

• No tax-free threshold — you're taxed from your very first dollar of income.
• 30% on income up to $135,000.
• 37% from $135,001 to $190,000.
• 45% above $190,000.
• No Medicare levy, but also no access to Medicare itself.

Special Rate for Working Holiday Makers

If you're on a Working Holiday visa (subclass 417 or 462), the ATO applies a specific "working holiday maker" tax rate: you don't get the tax-free threshold, but your first $45,000 of income is taxed at just 15%, rather than the standard 30% non-resident rate.

The Tax-Free Threshold If You Arrive Partway Through the Year

If you become an Australian tax resident partway through the financial year, your tax-free threshold is apportioned — not the full $18,200. It's calculated as a base amount plus an additional sum for each month you were a resident, counted from your arrival month through to 30 June. This means new arrivals pay slightly more tax on the same income than someone who was a resident for the full year, simply because their apportioned threshold is lower.

Why This Matters in 2026

With the introduction of the legislated tax cuts reducing the second income tax bracket to 15% and new simplified work-related expense measures in 2026–27, staying aligned with correct ATO withholding guidelines prevents over-paying or under-paying your tax obligations as a newcomer.

Getting Set Up: Your Tax File Number (TFN)

Every worker in Australia needs a Tax File Number, free to obtain from the ATO. Without one, your employer is legally required to withhold tax at the highest emergency rate — so apply as soon as possible after arrival, ideally before your first paycheck.

Understanding Superannuation

Superannuation ("super") is Australia's compulsory retirement savings system. Key facts for 2026:

• Employer contribution rate: 12% of your ordinary earnings, paid on top of your salary — this is a permanent rate as of 1 July 2025, the final scheduled increase.
• Contributions tax: Super contributions are taxed at just 15% inside the fund, significantly less than most people's marginal income tax rate.
• Concessional contribution cap: $32,500 for 2026–27 (includes employer contributions).

If you're on a temporary visa and leave Australia permanently, you may be eligible to claim back your superannuation through the Departing Australia Superannuation Payment (DASP) scheme — worth researching before you depart.

The Medicare Levy Surcharge

If your income exceeds certain thresholds (around $105,000 for singles in 2026–27) and you don't hold private hospital cover, you'll pay an additional 1%–1.5% Medicare Levy Surcharge on top of the standard 2% levy. Basic private hospital cover often costs less than the surcharge itself, making it worth comparing before tax time.

Application Checklist

• Apply for your Tax File Number immediately upon arrival.
• Determine your residency status using the ATO's official tests.
• Understand whether the working holiday maker tax rate applies to you.
• Check whether your income triggers the Medicare Levy Surcharge.
• Confirm your employer is correctly paying 12% superannuation on your behalf.
• Lodge your return by 31 October if self-filing, or engage a registered tax agent for a later deadline.
