ATO Tax Guide 2025-2026:
Brackets, Refunds
& Audit Red Flags.
Your payslip shows a gross salary you negotiated. Then the ATO takes its share — and what lands in your account is significantly less. Most Australians accept this without ever understanding exactly what is being taken, why, whether they’re paying the right amount, or what actually puts a return under review.
This guide walks through every component of Australian income tax for 2025–26 — the brackets, the Medicare levy, LITO, HELP/HECS, refund timelines, the ATO’s own audit red flags, the caravan and vehicle FBT ruling, and the changes confirmed for 2026–27 — with real worked examples and a free calculator for your personal numbers.
The Australian financial year runs from 1 July 2025 to 30 June 2026. Tax returns for this year are due by 31 October 2026 — or later if you use a registered tax agent. The earlier you understand your position, the earlier you can act on deductions, salary sacrifice, and super top-ups before the year closes.
Stage 3 Tax Cuts — What Changed and Why It Matters
The most significant change to Australian personal income tax in a decade took effect on 1 July 2024. The Stage 3 tax cuts, legislated under the Treasury Laws Amendment (Cost of Living Tax Cuts) Act 2024, restructured the middle and lower brackets substantially. The 2025–26 financial year is the second consecutive year under these rates — unchanged from 2024–25.
The key winners from Stage 3: anyone earning above $45,000 saves at least $804/year compared to the old system. At $100,000 gross, the saving is approximately $1,679/year. The 30% bracket now covers a wide $90,000 income range ($45,001 to $135,000) — meaning most full-time Australian workers sit inside a single dominant marginal rate in 2025–26.
Australian Income Tax Brackets 2025–26 — All 5 Zones
These are the official ATO income tax rates for Australian residents for the 2025–26 financial year. Remember: these are marginal rates that apply only to the income within each bracket — not to your entire income.
The first $18,200 of income every Australian resident earns is completely tax-free. It is the foundation of Australia’s progressive system.
Maximum: $0
Applies to: All resident earners
Note: Foreign residents get no tax-free threshold
Income from $18,201 to $45,000 is taxed at 16% — reduced from 19%. LITO of up to $700 significantly reduces the effective rate here.
Max tax: $4,288
($26,800 × 16%)
On $30,000 total income: $1,888
The widest bracket — $90,000 of income from $45,001 to $135,000, reduced from 32.5% under Stage 3.
Max tax: $27,000
($90,000 × 30%)
On $80,000 total: $10,500 in this bracket
Only income above $135,000 hits this rate — a common misconception is that all income is suddenly taxed at 37%. That is false.
Max tax: $20,350
($55,000 × 37%)
On $150,000 total: $5,550 in this bracket
Adding the 2% Medicare levy, the effective top marginal rate is 47%. Applies to roughly 3–4% of taxpayers.
Tax in bracket: $4,500
(only $10,000 above $190k)
Total tax + Medicare: ~$65,700

Use the Free ATO Tax Calculator →The Bracket Myth That Costs Australians Money
The most persistent and damaging myth in Australian personal finance: “If I get a pay rise that pushes me into a higher bracket, I might take home less money.” This is completely false — and the fear of it causes some people to turn down pay rises.
❌ The Myth vs ✅ The Reality — $135,000 vs $135,001
❌ What People Believe
“If I earn $135,001, my entire salary is taxed at 37% instead of 30%. A $1 pay rise could cost me thousands.”
✅ What Actually Happens
“Only that single dollar above $135,000 is taxed at 37%. My previous $135,000 is taxed exactly as before. My take-home pay increases by $0.63 from that extra dollar.”
In Australia’s progressive system, crossing a threshold never makes you worse off. A pay rise always increases your take-home pay — even if part of it moves into a higher bracket.

How Long Does a Tax Refund Take in 2025–26?
This is one of the most searched ATO questions every tax season, and the honest answer is: most electronically lodged returns are processed within 12 business days. Paper returns take considerably longer — often up to 10 weeks — because they require manual data entry before the ATO’s systems can assess them.
| Lodgement Method | Typical Processing Time | Common Delay Cause |
|---|---|---|
| myTax (online, e-lodged) | Up to 12 business days | Return flagged for manual review |
| Registered tax agent | 12–20 business days | Agent lodgement batching |
| Paper return | Up to 10 weeks | Manual data entry backlog |
| Amended return | Up to 20 business days | Requires reassessment of original |
If your refund is taking longer than expected, three things are almost always the cause: your bank account details are outdated in myGov, your return has been automatically flagged for the ATO’s data-matching checks (see the audit red flags section below), or you have an outstanding debt — HECS/HELP, Centrelink, or child support — that the refund is being offset against before it reaches you. You can track real-time status by logging into myGov and checking the ATO’s lodgement status page.
Why Do I Owe the ATO Money Instead of Getting a Refund?
A surprise tax bill is one of the most stressful outcomes of lodging a return, and it is almost never random. There are a handful of specific, well-known causes:
⚠️ Prevention Is Easier Than the Fix
The single most effective habit is reviewing your Tax File Number Declaration each time you start a new job or your income situation changes — particularly the tax-free threshold and HELP debt questions. Getting these right at the source avoids nearly all surprise bills.
ATO Tax Return Audit Red Flags — What Actually Triggers a Review
The ATO doesn’t manually review every return — it uses automated data-matching against banks, employers, share registries, property records, and other government agencies. When your lodged figures don’t line up with what those third parties report, your return is flagged for a closer look. Understanding the common triggers helps you lodge accurately the first time and avoid an unnecessary review.
Deductions well above your industry’s benchmark
The ATO publishes occupation-specific benchmarks for work-related expenses. Claiming significantly more than typical for your job — without matching evidence — is one of the most common triggers.
100% business-use claims on a vehicle
Very few people use a car exclusively for work with zero private use. Claiming 100% business use without a logbook is a well-known audit trigger — see the caravan and vehicle ruling below.
Rental property losses that don’t match reported income
Large negative-gearing losses claimed against a property with rental income figures that don’t reconcile with the loan and market rent data the ATO already holds.
Large, unexplained bank deposits
Banks report high-value and unusual transactions. A pattern of cash deposits with no corresponding declared income is a strong prompt for review.
Cash-in-hand income left undeclared
Industries with high cash turnover (hospitality, trades, personal services) receive extra scrutiny through the ATO’s benchmarking program.
Repeated late lodgements or frequent amendments
A pattern of late returns or multiple amendments to the same year raises your overall compliance risk profile with the ATO’s systems.
If your return is selected for review, it doesn’t automatically mean wrongdoing — many reviews close with no change once supporting evidence (receipts, logbooks, contracts) is provided. Keeping records for at least five years, as the ATO requires, is the simplest protection.
ATO Caravan & Vehicle Tax Ruling — What It Means for Your Deductions
The ATO’s guidance on caravans and other vehicles has become a frequently searched topic as more Australians combine work and travel. The core principle is straightforward but often misapplied: any private use of a vehicle or caravan reduces the deductible or FBT-exempt portion — there is no such thing as an automatic 100% work-use claim just because the vehicle is registered to a business or used occasionally for a work trip.
If Your Employer Provides the Vehicle or Caravan
Where an employer provides a vehicle (including a caravan used for remote or fly-in-fly-out work) that is also available for private use, it generally falls under Fringe Benefits Tax (FBT) rather than being deducted through the employee’s individual return. The employer, not the employee, is responsible for FBT obligations in this case.
If You’re Self-Employed or Claiming Individually
Individuals and sole traders must apportion the deduction based on actual work-related use, evidenced through a valid logbook kept for a minimum 12-week representative period, or the cents-per-kilometre method for lower-use claims. A caravan or vehicle used for a family holiday during the same period it’s claimed as 100% business cannot support that claim under an ATO review — this exact mismatch between claimed use and observable travel patterns (registration, fuel, toll records) is one of the more specific audit triggers the ATO has flagged in recent guidance.
How to Check Your TFN & Spot ATO Scam Warnings
Search interest in “how to check TFN” and “ATO tax return warning” spikes every tax season for two very different reasons — people genuinely need their number, and scammers exploit that exact moment of uncertainty.
Finding Your Tax File Number
Your TFN appears on: a previous notice of assessment, a payslip from a current or recent employer, your myGov account once linked to the ATO, or a letter from the ATO or your superannuation fund. If none of these are accessible, the ATO can reissue confirmation through myGov or, for identity-verified cases, by phone.
Recognising a Genuine ATO Tax Return Warning vs a Scam
The ATO will never ask for your TFN, bank login, or payment details via SMS link, unsolicited phone call, or social media message, and it never demands payment through gift cards, cryptocurrency, or direct bank transfer to a personal account. If you receive a message claiming a return is under warning or a payment is overdue, do not click any embedded link — log into myGov directly and check your account status there instead.
⚠️ Three-Second Scam Check
Urgency + a payment method that isn’t a standard bank transfer to the ATO’s official BPAY details + a request to click a link = almost certainly a scam. Genuine ATO correspondence is always visible inside your myGov inbox, not only in a text message.
Medicare Levy vs Medicare Levy Surcharge — They Are Not the Same
These two charges are consistently confused. They are completely different in how they work, who pays them, and what they fund.
Medicare Levy (2% — Almost Everyone Pays This)
The Medicare levy is a 2% charge on your taxable income that funds Australia’s public healthcare system (Medicare). Low‑income earners are exempt: singles earning below $27,000 pay no Medicare levy. A shade‑in zone from $27,000 to $33,750 applies a reduced rate of 10% of the amount above $27,000. Above $33,750, the full 2% applies.
Medicare Levy Surcharge (1%–1.5% — Only If You Earn Above $96,000 Without Private Health)
The Medicare Levy Surcharge (MLS) is a completely separate charge that applies only if: (1) your income for MLS purposes exceeds $96,000 (singles) or $192,000 (families) in 2025–26, AND (2) you do not hold appropriate private hospital cover for the full year.
| Income (Singles, 2025–26) | MLS Rate | Annual MLS on $100,000 | Cheapest Cover Alternative |
|---|---|---|---|
| Below $96,000 | 0% — No MLS | $0 | N/A |
| $96,001 – $112,000 | 1.0% | $1,000 at $100,000 | Basic hospital cover ~$360–$600/yr |
| $112,001 – $151,000 | 1.3% | $1,560 at $120,000 | Basic hospital cover ~$360–$600/yr |
| Above $151,000 | 1.5% | $2,400 at $160,000 | Basic hospital cover ~$360–$600/yr |
⚠️ The Private Health Maths Almost Always Favours Cover
At $100,000 income without private hospital cover, you pay $1,000 MLS. Basic private hospital cover starts from about $30–$50/month ($360–$600/year) — you can compare policies via privatehealth.gov.au. The cover costs less than the surcharge — and you also get the healthcare benefit.
Low Income Tax Offset (LITO) 2025–26 — How It Works
The LITO is an offset that directly reduces the amount of tax you owe — dollar for dollar. A $700 LITO means $700 less tax, not $700 less taxable income.
The LITO phases out across two income ranges: first at 5 cents per dollar between $37,500 and $45,000, then at 1.5 cents per dollar between $45,000 and $66,667. The offset is applied automatically by the ATO — you do not claim it separately.
HECS/HELP Repayment Thresholds 2025–26
If you studied at an Australian higher education provider, you likely have a HELP debt. It is repaid compulsorily through the tax system once your repayment income exceeds $67,000. Below that, no compulsory repayment is required.
| Repayment Income 2025–26 | Repayment Rate | Annual Repayment at Bottom of Tier | Status |
|---|---|---|---|
| Below $67,000 | Nil | $0 | No repayment |
| $67,000 – $77,999 | 1.0% | $670 | Low |
| $78,000 – $91,999 | 2.0% | $1,560 | Low |
| $92,000 – $99,999 | 2.5% | $2,300 | Medium |
| $100,000 – $109,999 | 3.0% | $3,000 | Medium |
| $110,000 – $120,999 | 3.5% | $3,850 | High |
| $121,000 – $130,999 | 4.0% | $4,840 | High |
| Above $279,000 | 10.0% | $27,900 | Maximum |
⚠️ HELP Repayment Is Based on Repayment Income — Not Just Salary
Your HELP repayment threshold is calculated on repayment income — which includes your salary PLUS reportable fringe benefits, reportable employer super contributions, and total net investment losses. This is one reason HELP debt is a frequent cause of the “why do I owe money” surprise covered earlier.
Superannuation Guarantee 2025–26
The Superannuation Guarantee (SG) rate from 1 July 2025 is 12% — the final permanent rate. Your employer pays 12% of your ordinary time earnings on top of your salary, not from it. From 1 July 2026, Payday Super rules will require super to be paid on each payday, with contributions due within 7 business days.
Key super facts for 2025–26: concessional contributions cap: $30,000 (including employer contributions). Tax inside super on concessional contributions: 15%. Division 293 tax: high earners above $250,000 taxable income pay an additional 15% contributions tax inside super.

What Changes in 2026–27? The Second Tax Cut Phase
The Government has announced a further reduction in the lowest tax bracket rate from 16% to 15% on income between $18,201 and $45,000, effective 1 July 2026. A further cut to 14% has been announced for 1 July 2027. Both measures require legislative approval and are not yet law.
The maximum annual saving from the proposed 2026–27 change is $268 — modest individually, but applying to over 11 million taxpayers. The subsequent 14% rate is also subject to Parliament.
Expert Pro Tips to Reduce Your Australian Tax Bill
Preparing Your Return Before October
Tax returns for FY 2025–26 are due 31 October 2026. Identify every deductible expense you can claim — home office days, work vehicle use, professional development, tools, subscriptions. Use the ATO tax calculator to estimate your refund before you lodge.
Evaluating a Job Offer or Pay Rise
You have been offered $95,000. After income tax and Medicare levy, your take‑home is approximately $71,000 – $72,000 per year, depending on HECS and MLS. Know your real net income before accepting, especially if relocating cities with a different cost of living.
Newly Self-Employed With a Work Vehicle
Starting to claim vehicle expenses for the first time? Set up a logbook from day one rather than reconstructing use later — it’s the single biggest protection against the audit triggers covered above.
Immigrant or Newcomer to Australia
New to Australia and confused by your first payslip? The tax-free threshold ($18,200), Medicare levy (2%), and PAYG withholding system explain most of what your employer deducts. Claim the tax-free threshold with your primary employer only.

Three Things to Take Away and Act On Before 30 June 2026
Australian income tax for 2025–26 is more transparent and more generous than most people realise. The Stage 3 cuts mean most full-time workers pay less tax than they did three years ago. But understanding the system — and knowing exactly what draws ATO attention — is still essential for making the right decisions on super, deductions, and vehicle or property claims.
First: Calculate your real take-home pay using the free ATO tax calculator below. Know exactly what you earn after tax before you make any financial commitment — mortgage, rent, investment, or life change.
Second: Act before 30 June 2026. Super contributions, deductible expense prepayments, and private hospital cover decisions must all be made within the current financial year to affect your 2025–26 return.
Third: If anything you claim involves mixed personal and work use — a vehicle, a caravan, a home office — keep the evidence as you go. It’s the difference between a routine review closing quietly and a drawn-out dispute.
