ATO Tax Calculator 2025–26 & 2026–27: Calculate Your Australian Income Tax Instantly

Every Australian employee needs to know what they actually take home — not just their gross salary. The ATO tax calculator on this page doubles as a full income tax calculator and take home pay calculator, using the official Australian Taxation Office tax brackets for both the current FY 2025–26 year and the upcoming FY 2026–27 year, which introduces a further rate cut on the lowest bracket. Whether you are an employee, contractor, or comparing a job offer, this tool gives you an accurate estimate in seconds — annually, monthly, fortnightly, or weekly — for whichever year matters to you.

Australian tax time for 2025–26 runs from 1 July 2025 to 30 June 2026, with returns due by 31 October 2026. The 2026–27 year begins 1 July 2026. Getting your estimate right now — for either year — helps you plan deductions, salary sacrifice, and super contributions.

How to Use This ATO Tax Calculator

The calculator is designed to be fast and simple. Follow these steps:

1. Enter your income — type your annual, monthly, or weekly gross salary before tax.
2. Select financial year — choose FY 2025–26 (1 Jul 2025 – 30 Jun 2026) or FY 2026–27 (1 Jul 2026 – 30 Jun 2027), which uses the reduced 15% second-bracket rate.
3. Set your residency — Australian residents, foreign residents, and Working Holiday Makers (visa 417/462) all face different rates.
4. Toggle HELP/HECS ⓘ — if you have a student loan, the ATO uses a marginal repayment system starting at $67,000 income.
5. Check private health insurance — without hospital cover, high earners pay a Medicare Levy Surcharge of 1%–1.5% on top of the standard 2% Medicare levy.
6. Add deductions — work‑related expenses, donations, and other deductions reduce your taxable income before tax is calculated.
7. View results — click Calculate My Tax and see your full breakdown: income tax, Medicare levy, LITO offset, HELP repayment, take‑home pay, and employer super — annually, monthly, fortnightly, or weekly.

How Australian Income Tax Works

Australia uses a progressive income tax system ⓘ, which means you pay more tax as you earn more — but only on the income that falls within each bracket. You never pay a higher rate on your entire income when you cross a threshold; only the extra dollars above the threshold are taxed at the new rate.

The Stage 3 tax cuts, legislated under the Treasury Laws Amendment (Cost of Living Tax Cuts) Act 2024, changed the brackets from 1 July 2024. A further cut is scheduled for 1 July 2026: the 16% rate on the second bracket drops to 15%. Every Australian earning above $45,000 will save an additional amount on top of the Stage 3 savings once FY 2026–27 begins.

The Australian financial year runs from 1 July to 30 June. Most workers pay tax through PAYG (Pay As You Go) ⓘ withholding, where employers deduct tax from each pay. After June 30, you lodge a tax return and either receive a refund or pay additional tax depending on your exact circumstances.

Australian Tax Brackets 2025–26 & 2026–27

These are the official Australian tax brackets for Australian residents, sourced directly from the Australian Taxation Office. Use them alongside the calculator above, or as a quick reference on their own — including the confirmed tax brackets 2026 update taking effect 1 July 2026:

Plus Medicare Levy ⓘ: 2% of taxable income for most Australian residents. Low‑income earners are exempt: the full exemption applies up to $27,222, with a shade‑in zone up to $34,027 (2025–26 thresholds; 2026–27 thresholds are indexed slightly higher).

For foreign residents (non‑residents): no tax‑free threshold. Income up to $135,000 is taxed at a flat 30%, then 37% and 45% at the same thresholds — unchanged in 2026–27.

Working Holiday Makers (visa 417/462): flat 15% on income up to $45,000, then 30% up to $135,000, 37% up to $190,000, and 45% above.

Weekly & Fortnightly Tax Tables and Take-Home Pay

Most Australians are paid fortnightly or weekly, not annually — so seeing your tax as a yearly lump sum isn’t always useful. The calculator above works as a weekly tax calculator or fortnightly tax calculator as well as an annual one: switch the pay frequency toggle and every result — income tax, Medicare levy, and take-home pay — recalculates instantly for that period.

If you just need a quick reference rather than entering your exact figures, here’s how a $80,000 annual salary (2025–26, no HELP) breaks down by weekly tax table and fortnightly tax table equivalents:

These figures follow the same ATO withholding schedule used in the official weekly and fortnightly tax tables, but with your actual income tax and Medicare levy applied precisely rather than rounded to a withholding bracket — which is why the calculator above is often more accurate than a printed tax table for figuring out your real take-home pay.

Worked Examples by Income Level (FY 2025–26)

Most calculators only show you one example salary. Here’s the breakdown at three common income levels so you can find the one closest to your own situation:

Key Offsets & Deductions That Reduce Your Australian Tax Bill

Low Income Tax Offset (LITO) ⓘ

The LITO reduces your income tax payable by up to $700 if your taxable income is $37,500 or below. It phases out between $37,500 and $66,667. At $80,000, you receive no LITO. This offset automatically applies — you do not need to claim it separately.

Work‑Related Deductions

You can deduct the cost of earning your income: home office expenses, vehicle use for work, uniforms, tools, professional subscriptions, and self‑education related to your current job. The current threshold for claiming without written evidence is $300; a government proposal to increase it to $1,000 has not yet been legislated.

Salary Sacrifice to Super

Pre‑tax salary sacrificed into superannuation reduces your taxable income. Super contributions are taxed at 15% inside the fund — significantly less than most people’s marginal rate. The concessional cap is $30,000 in 2025–26 (including employer contributions).

Medicare Levy Surcharge (MLS) Avoidance

If your income exceeds $101,000 (singles) in 2025–26 and you do not hold private hospital cover, you pay an additional 1%–1.5% MLS on top of the standard 2% Medicare levy. Basic private hospital cover (from ~$30–$50/month) typically costs less than the surcharge. The 2026–27 MLS threshold rises to $105,000.

HELP / HECS Repayments ⓘ

Use the calculator above as a HECS repayment calculator by toggling on HELP/HECS — it applies the same marginal repayment system the ATO uses. For a single, compulsory repayment begins at $67,000 taxable income — you pay 15 cents for every dollar above $67,000 up to $125,000. Above $125,000, the rate increases to 17 cents per dollar over $125,000, and for incomes over $179,285, the repayment is a flat 10% of total income. Note: the ATO applied a 20% reduction to all student loan balances that existed on 1 June 2025.

Common Mistakes Australians Make at Tax Time

1. Confusing marginal tax rates with your effective rate. Australia’s marginal tax rates (e.g. 30%) only apply to the last dollars you earn — not your whole salary. On $80,000, your effective rate is about 20.5%, not 30%.
2. Not claiming all work deductions. Many Australians under‑claim home office expenses, vehicle use, and professional development. Keep records throughout the year, not just at June.
3. Forgetting to update tax withholding after a salary change. If you get a raise mid‑year, update your withholding tax variation with your employer to avoid a surprise bill in October.
4. Using outdated calculators with old rates. Some tools still show pre-Stage-3 rates, or don’t yet reflect the confirmed 2026–27 cut to 15% — resulting in inaccurate estimates in either direction.
5. Missing the HELP repayment income threshold. Your HELP repayment is calculated on repayment income (including fringe benefits and reportable super), not just your salary. Many people are surprised by an unexpected HELP repayment at lodgement.

5 Legal Ways to Reduce Your Australian Tax

1. Maximise concessional super contributions. Contribute up to $30,000 (including employer contributions) before 30 June. Each dollar contributed reduces your taxable income at your marginal rate and is taxed at only 15% inside the fund.
2. Claim home office expenses properly. The ATO’s fixed rate method allows 67 cents per hour worked from home. Keep a diary record from 1 July — this is the most under‑utilised deduction for employees.
3. Pre‑pay deductible interest or subscriptions. Under ATO rules, you can pre‑pay up to 12 months of deductible expenses (investment loan interest, professional memberships) in the current year to bring the deduction forward.
4. Consider an investment structure review. Income‑producing assets held in a spouse’s name with a lower marginal rate, or through a family trust, can legally distribute income to lower‑rate taxpayers. Speak to a registered tax agent.
5. Lodge your return early if you are due a refund. The ATO processes most returns within 12 business days. Lodging in July rather than October means you receive any refund months sooner — money you can immediately deploy into super or investments.

Why Use This Instead of the Official ATO Calculator?

The ATO’s own Income Tax Estimator is thorough but takes 15–25 minutes and is built for a full return, not a quick check. Its Simple Tax Calculator is faster but splits Medicare levy, LITO, and HELP across separate tools you have to run one at a time. This calculator combines all of it — income tax, Medicare levy, LITO, HELP repayment, and take-home pay — into one result, for both FY 2025–26 and FY 2026–27, in under a minute, with no login and no data stored.
