Understanding how much income tax you owe is one of the most practical financial skills any working Australian can develop. Whether you are starting your first job, negotiating a pay rise, planning a career change, or simply trying to figure out how much of your salary actually lands in your bank account each fortnight, income tax sits at the centre of the calculation. The Australian Taxation Office (ATO) collects income tax on behalf of the federal government, and the amount you pay depends on how much you earn, what deductions you can claim, and which offsets or levies apply to your situation. This guide explains everything you need to know about Australian income tax for the 2026-27 financial year, and shows you exactly how to use our income tax calculator to estimate your liability, marginal rate, Medicare levy, and take-home pay. It is written for everyday Australians who want clear answers without wading through pages of legislative jargon.
What Is Income Tax?
Income tax is a tax levied by the Australian government on the income earned by individuals, companies, trusts, and other entities during a financial year. For most people reading this guide, that means the money you earn from employment, self-employment, investments, rental properties, and certain government payments. The financial year in Australia runs from 1 July to 30 June, so the 2026-27 financial year covers the period from 1 July 2024 to 30 June 2025.
Australia uses a progressive tax system, which means the rate of tax increases as your taxable income rises. You do not pay the same percentage on every dollar you earn. Instead, different portions of your income are taxed at different rates as they pass through each tax bracket. This is a fundamental concept that many people misunderstand, and it leads to one of the most common tax myths in Australia: the idea that earning a dollar more can somehow leave you worse off because you have moved into a higher tax bracket. We will address that misconception later in this guide.
The ATO administers the income tax system and requires most taxpayers to lodge an annual tax return. Your employer typically withholds tax from your pay throughout the year under the Pay As You Go (PAYG) withholding system. At the end of the financial year, your tax return reconciles what was withheld against what you actually owe, which may result in a refund or an additional tax bill.
Who Pays Income Tax in Australia?
Australian residents for tax purposes are generally taxed on their worldwide income. If you live in Australia, hold permanent residency, or satisfy the resides test or domicile test, you are likely an Australian tax resident. Non-residents are taxed differently: they pay tax on Australian-sourced income only and do not receive the tax-free threshold on the first $18,200 of income.
Temporary residents may also have different rules depending on their visa status and circumstances. This guide focuses on Australian resident individuals, which covers the vast majority of people using a standard income tax calculator for salary and wage earners.
Tax Brackets for 2026-27
The tax brackets for Australian resident individuals changed on 1 July 2024 as a result of the Stage 3 tax cuts legislated by the federal government. These changes reduced tax for most income earners by lowering marginal rates and adjusting bracket thresholds. Our calculator uses the current 2026-27 resident individual rates shown in the table below.
| Taxable Income | Tax Rate | Tax on This Bracket |
|---|---|---|
| $0 – $18,200 | 0% | Nil |
| $18,201 – $45,000 | 16% | 16c for each $1 over $18,200 |
| $45,001 – $135,000 | 30% | $4,288 plus 30c for each $1 over $45,000 |
| $135,001 – $190,000 | 37% | $35,100 plus 37c for each $1 over $135,000 |
| $190,001 and over | 45% | $51,600 plus 45c for each $1 over $190,000 |
The tax-free threshold of $18,200 means that if your taxable income is at or below this amount, you pay no income tax at all. This threshold has been a feature of the Australian system for many years and provides meaningful relief for low-income earners, part-time workers, and students who only work casually during the year.
The jump from 16% to 30% at $45,001 is the largest bracket change in the 2026-27 scale. If your taxable income is $45,000 exactly, your income tax is $4,288. If it is $45,001, you pay $4,288 plus 30 cents on that extra dollar, which is $4,288.30. Moving into a higher bracket never reduces your overall take-home pay.
Medicare Levy
In addition to income tax, most Australian residents pay the Medicare levy. This is a separate charge that helps fund Australia's public health system. For the 2026-27 financial year, the standard Medicare levy rate is 2% of your taxable income.
However, low-income earners may pay a reduced levy or no levy at all. For singles with no dependants, the full 2% levy generally applies once taxable income exceeds $23,226. Below that threshold, no Medicare levy is payable. Between $23,226 and $29,033, a shaded reduction applies, meaning you pay a partial levy rather than the full 2%.
Our calculator applies a simplified Medicare levy estimate: if your taxable income is above $23,226, it calculates 2% of your entire taxable income. If your income is at or below $23,226, no Medicare levy is included. This is a reasonable approximation for most middle and higher income earners but may overstate the levy slightly for those in the shaded zone just above the threshold.
Medicare Levy Surcharge
High-income earners without appropriate private hospital cover may also be liable for the Medicare Levy Surcharge (MLS), which is an additional 1% to 1.5% on top of the standard levy. The MLS applies to singles earning above $97,000 and families above $194,000 (2026-27 thresholds, with adjustments for dependants). Our basic income tax calculator does not include the MLS, so if you are a high earner without private hospital insurance, your actual liability may be higher than the estimate shown.
HELP and HECS Repayments
If you have a Higher Education Loan Program (HELP) debt, formerly known as HECS, your repayments are handled separately from standard income tax withholding but are still collected through the tax system. Once your repayment income exceeds the minimum threshold, the ATO calculates a compulsory repayment as a percentage of your income. For 2026-27, the minimum repayment threshold is $54,435, at which point the repayment rate is 1% of your repayment income. The rate increases progressively, reaching 10% for repayment income of $159,664 and above.
Repayment income includes your taxable income plus any reportable fringe benefits, net investment losses, and other adjustments. This means your HELP repayment can be triggered even if your salary alone appears below a threshold once other income sources are included.
Important Note
Our income tax calculator does not include HELP or HECS compulsory repayments. If you have a student loan, your actual take-home pay after all obligations will be lower than the calculator shows. Check the ATO's HELP repayment thresholds and rates for 2026-27 to estimate your additional repayment amount.
Tax Offsets Overview
Tax offsets, sometimes called rebates, directly reduce the amount of tax you owe rather than reducing your taxable income. Deductions lower the income figure that tax is calculated on; offsets reduce the tax bill itself. Understanding the difference matters when you are trying to estimate your liability.
Low Income Tax Offset (LITO)
The Low Income Tax Offset is the primary offset available to resident individuals in 2026-27. The maximum offset is $700 for those with taxable income of $37,500 or less. The offset gradually reduces as income rises: it decreases by 5 cents for each dollar of taxable income between $37,500 and $45,000, and then by 1.5 cents for each dollar between $45,000 and $66,667. Once taxable income reaches $66,667, the LITO is fully phased out and no longer applies.
For example, someone with taxable income of $40,000 receives a LITO of $575 (the maximum $700 minus 5 cents times the $2,500 above $37,500). Someone earning $60,000 receives a much smaller offset. Our calculator does not currently apply LITO automatically, so your actual tax may be slightly lower than shown if you qualify for this offset.
Other Offsets
Several other offsets exist for specific circumstances, though they are less commonly encountered in a basic salary calculator:
- Seniors and pensioners tax offset (SAPTO): Available to eligible seniors and pensioners who meet age and income requirements.
- Private health insurance rebate: A partial rebate on the cost of private health insurance premiums, income-tested and claimed either as a premium reduction or a tax offset in your return.
- Zone and overseas forces offsets: For taxpayers living in remote areas or serving in specified overseas locations.
- Spouse super contributions offset: For contributions made on behalf of a low-income or non-working spouse.
The Low and Middle Income Tax Offset (LMITO), which provided temporary relief of up to $1,500 during previous years, has not been extended and does not apply in 2026-27.
PAYG Withholding vs Annual Tax
Most employees in Australia do not pay their entire tax bill in one lump sum at the end of the year. Instead, employers withhold tax from each pay cycle under the Pay As You Go (PAYG) withholding system. The amount withheld is based on tables published by the ATO that account for your income, tax file number declaration, and any claimed tax-free threshold.
PAYG withholding is designed to spread your tax liability across the year. When you lodge your tax return after 30 June, the ATO compares the total tax withheld during the year against your actual tax liability calculated on your full annual income, deductions, and offsets. If too much was withheld, you receive a refund. If too little was withheld, you owe the difference.
Several situations commonly cause a difference between PAYG withholding and your final tax bill. You may have changed jobs mid-year, earned income from multiple employers, had significant deductions that were not reflected in withholding, received a bonus taxed at a higher marginal rate through the schedule, or earned investment income that had no tax withheld at all. Self-employed individuals and contractors typically pay tax through PAYG instalments rather than withholding, making annual reconciliation even more important.
PAYG Withholding
Tax deducted from your salary each pay period by your employer. Based on estimated annual income and ATO withholding schedules. Provides regular prepayment of your expected tax liability throughout the year.
Annual Tax Assessment
Your actual tax calculated when you lodge your return. Accounts for total income, all deductions, offsets, Medicare levy, and any other adjustments. The final word on what you owe or are owed.
How to Use the Income Tax Calculator
Our Australian income tax calculator for 2026-27 is designed to give you a quick, clear estimate of your tax position based on two simple inputs. Here is what each field means and how to enter your information accurately.
Annual Gross Income
Enter your total income before any tax is deducted. For salaried employees, this is your annual salary plus any regular taxable allowances, bonuses, and overtime expected over the full financial year. Include bank interest, dividend income, and rental income if you want a complete picture, or enter salary alone for a employment-only estimate. Do not subtract superannuation contributions made by your employer, as employer super is not part of your assessable income.
Tax Deductions
Enter the total amount of allowable tax deductions you expect to claim for the year. Common deductions include work-related expenses, charitable donations, tax agent fees, and the cost of managing tax affairs. If you are unsure, enter zero for a baseline estimate based on gross income alone. The calculator subtracts deductions from gross income to arrive at taxable income.
What the Results Mean
After entering your figures, the calculator displays several results that together paint a picture of your tax position:
- Taxable Income: Gross income minus deductions. This is the figure used to calculate tax.
- Income Tax: Tax calculated using the 2026-27 progressive rate scale.
- Medicare Levy: Estimated 2% levy if taxable income exceeds $23,226.
- Total Tax: Income tax plus Medicare levy combined.
- Marginal Rate: The tax rate that applies to your next dollar of income.
- Effective Rate: Total tax as a percentage of taxable income, showing your overall tax burden.
- Estimated Take-Home Pay: Gross income minus total tax, representing what you keep.
Step-by-Step: How Income Tax Is Calculated
Calculating Australian income tax manually follows a clear sequence. Understanding each step helps you verify calculator results and builds intuition about how changes to income or deductions affect your tax bill.
- Determine gross income. Add up all assessable income for the financial year, including salary, wages, bonuses, interest, dividends, rental income, and business income.
- Subtract allowable deductions. Deduct work-related expenses, gifts to deductible gift recipients, and other eligible claims to arrive at taxable income.
- Apply the tax-free threshold. No tax is payable on the first $18,200 of taxable income.
- Calculate tax in each bracket. Apply the relevant rate to each portion of income that falls within each bracket, using the cumulative amounts shown in the tax table.
- Add the Medicare levy. If taxable income exceeds $23,226, apply 2% (subject to low-income exemptions and shading).
- Subtract any tax offsets. Offsets such as LITO reduce the tax payable. Our calculator does not apply offsets automatically.
- Calculate take-home pay. Subtract total tax from gross income to find what remains.
Taxable Income = Gross Income − Deductions
Income Tax = Progressive rates applied to taxable income
Take-Home Pay = Gross Income − Income Tax − Medicare Levy
Worked Examples
The best way to understand income tax is to walk through real numbers. The following examples use the 2026-27 tax rates and match the logic in our calculator.
Example 1: Part-Time Worker on $35,000
Sarah, retail assistant, no deductions
Tax on income above $18,200: ($35,000 − $18,200) × 16% = $2,688
Sarah's marginal rate is 16%. Her effective rate is 9.7%. She may also qualify for a LITO of around $575, which would reduce her actual tax below this estimate.
Example 2: Full-Time Professional on $85,000
James, accountant, no deductions
Bracket 2 ($18,201–$45,000): ($45,000 − $18,200) × 16% = $4,288
Bracket 3 ($45,001–$85,000): ($85,000 − $45,000) × 30% = $12,000
Total income tax: $4,288 + $12,000 = $16,288
James's marginal rate is 30%. His effective rate is 21.2%. Every additional dollar he earns is taxed at 30 cents plus 2 cents Medicare levy until he reaches $135,001.
Example 3: Senior Manager on $120,000 with Deductions
Priya, project manager, $5,000 in deductions
Bracket 2: $4,288
Bracket 3: ($115,000 − $45,000) × 30% = $21,000
Total income tax: $4,288 + $21,000 = $25,288
Priya's $5,000 in deductions saved her approximately $1,600 in income tax plus $100 in Medicare levy compared to claiming nothing. Her marginal rate is 30% and her effective rate is 24.0%.
Tax Deductions Explained
Deductions reduce your taxable income, which in turn reduces the amount of tax you pay. The value of a deduction depends on your marginal tax rate: a $1,000 deduction saves you $160 if you are in the 16% bracket, but $450 if you are in the 45% bracket. You can only claim deductions for expenses that are directly related to earning your income, and you must be able to substantiate your claims with records.
Common Work-Related Deductions
- Vehicle and travel expenses: Costs for travel between work sites (not commuting from home to your regular workplace), using either the cents-per-kilometre method or a logbook.
- Uniforms and protective clothing: Occupation-specific clothing, protective gear, and laundry costs for eligible items.
- Self-education expenses: Courses and study materials directly connected to your current employment, subject to certain restrictions.
- Tools and equipment: Items you purchase for work use, which may be claimed outright if under $300 or depreciated over time if more expensive.
- Working from home expenses: A fixed rate of 67 cents per hour or actual cost methods for home office running expenses.
- Phone and internet: The work-related portion of mobile phone and internet bills.
Other Deductions
- Charitable donations: Gifts of $2 or more to deductible gift recipients (DGRs) registered with the ATO.
- Cost of managing tax affairs: Fees paid to a registered tax agent for preparing and lodging your return.
- Income protection insurance: Premiums for policies that replace lost income (but not life, trauma, or critical illness insurance).
- Investment expenses: Costs related to managing investments, such as account-keeping fees and advice fees, though capital expenses are treated differently.
The $300 Rule
For many work-related expense categories, you can claim up to $300 without written evidence, provided the claims are reasonable. Above $300 total for a category, you need receipts and records. The ATO uses data matching and random audits to verify claims, so keep your records for at least five years.
Marginal Rate vs Effective Rate
These two rates answer different questions and are both displayed in our calculator for good reason. Confusing them leads to poor financial decisions, so it is worth taking a moment to understand the distinction clearly.
Marginal Tax Rate
Your marginal tax rate is the rate of tax applied to your last dollar of income. It tells you how much tax you would pay on the next dollar you earn. If your taxable income is $85,000, your marginal rate is 30% because the next dollar falls in the $45,001 to $135,000 bracket. Marginal rate is the number you should use when evaluating decisions like overtime, a salary increase, or the tax impact of additional investment income.
Effective Tax Rate
Your effective tax rate is your total tax (including Medicare levy) divided by your taxable income, expressed as a percentage. It represents your overall tax burden as a share of everything you earn. For someone on $85,000 with no deductions, the effective rate is approximately 21.2%, well below the 30% marginal rate, because a large portion of income is taxed at 0% and 16%.
Quick Comparison at $85,000 Taxable Income
The gap between these two figures illustrates why the progressive system is designed to be fair: lower portions of income are taxed lightly, while higher portions bear more of the burden.
Tax Planning Tips for 2026-27
Smart tax planning is not about avoiding tax illegally. It is about understanding the rules and making informed decisions within them. Here are practical strategies relevant to the current financial year.
Salary Sacrifice into Superannuation
Contributions from pre-tax income into your super fund are taxed at 15% rather than your marginal rate. This can be especially valuable if you earn above $45,000. Be mindful of the concessional contributions cap of $30,000 per year (including employer contributions).
Track Deductions Throughout the Year
Do not wait until tax time to hunt for receipts. Use a simple spreadsheet or app to log work expenses as they occur. Missing deductions is effectively leaving money on the table.
Consider Private Health Insurance
If your income exceeds the Medicare Levy Surcharge thresholds ($97,000 for singles in 2026-27), appropriate private hospital cover can save you from paying the surcharge of 1% to 1.5%. Compare the cost of premiums against the surcharge amount.
Time Deductions and Income Where Possible
If you expect to be in a higher tax bracket next year, consider deferring deductions or accelerating income strategically. This is more relevant for self-employed individuals and those with variable income.
Review Your PAYG Withholding
If you consistently receive large refunds or tax bills, adjust your withholding by updating your tax file number declaration with your employer or requesting a variation through the ATO.
Common Mistakes to Avoid
Even experienced taxpayers make errors that cost them money or attract ATO attention. Being aware of the most frequent mistakes helps you lodge an accurate return and set realistic expectations when using a calculator.
- 1. Thinking your entire income is taxed at your top rate: This is the most pervasive myth in Australian tax. Moving from $44,999 to $45,001 does not mean all your income is suddenly taxed at 30%. Only the dollar above $45,000 is taxed at the higher rate.
- 2. Forgetting to include all income sources: The ATO receives data from employers, banks, share registries, and other sources. Omitting interest, dividends, or a second job from your return will likely be detected through data matching.
- 3. Claiming personal expenses as work deductions: Commuting from home to your regular workplace, everyday clothing, and personal meals are not deductible. The ATO publishes occupation-specific guides listing what is and is not claimable.
- 4. Ignoring the Medicare Levy Surcharge: High earners without private hospital cover may owe significantly more than a basic calculator shows. Check whether the surcharge applies to you before relying on a simple estimate.
- 5. Not accounting for HELP repayments: Graduates with student debt face compulsory repayments on top of income tax. A salary of $60,000 triggers a 2% HELP repayment on repayment income, which is not reflected in our calculator.
- 6. Using gross salary when you have significant deductions: Entering your full salary without subtracting expected deductions overstates your tax. If you know you will claim $3,000 in work expenses, include that in the deductions field.
Frequently Asked Questions
When do the 2026-27 tax rates apply?
The 2026-27 financial year runs from 1 July 2024 to 30 June 2025. The updated tax brackets and Stage 3 tax cuts took effect from 1 July 2024. When you lodge your tax return for this year (typically between July and October 2025), these are the rates that apply.
Do I need to lodge a tax return?
You must lodge a tax return if your taxable income exceeds the tax-free threshold of $18,200, unless the ATO has notified you that lodging is not necessary. Even if your income is below the threshold, you may want to lodge to claim a refund of tax withheld or to report deductible expenses.
Is superannuation taxed?
Employer superannuation guarantee contributions are not included in your assessable income and do not appear in the income tax calculator. Contributions are taxed at 15% within the super fund. When you access super in retirement, different tax rules apply depending on your age and the type of benefit.
What is the difference between a tax deduction and a tax offset?
A deduction reduces your taxable income before tax is calculated. An offset reduces the tax payable after it has been calculated. A $1,000 deduction saves you tax at your marginal rate (e.g. $300 at 30%), while a $1,000 offset reduces your tax bill by the full $1,000 (subject to offset caps and phase-outs).
How accurate is this calculator?
Our calculator provides a solid estimate for Australian resident individuals using the official 2026-27 tax brackets and a simplified Medicare levy calculation. It does not include LITO, HELP repayments, Medicare Levy Surcharge, private health rebate, or other offsets and adjustments. Use it for planning purposes and consult a registered tax agent for your actual return.
Can I claim working from home expenses?
Yes. For 2026-27, the ATO offers a fixed rate method of 67 cents per hour worked from home, covering electricity, internet, phone, stationery, and computer consumables. Alternatively, you can use the actual cost method if you keep detailed records. You cannot claim mortgage interest or rent under the fixed rate method.
What happens if I have two jobs?
Each employer withholds tax based on the assumption that their job is your only source of income. If you work two part-time jobs that individually fall below the tax-free threshold but combined exceed it, you may end up with a tax bill at the end of the year because insufficient tax was withheld overall. Consider requesting no tax-free threshold from one employer.
Are COVID-related tax concessions still available?
Most temporary COVID-19 tax measures have expired. The fixed rate for working from home was updated to 67 cents per hour from 1 July 2022 and continues to apply. Temporary full expensing for business assets has also ended, replaced by the permanent instant asset write-off for eligible small businesses.
Recent Tax Changes for 2026-27
The most significant change for the 2026-27 financial year is the implementation of the revised Stage 3 tax cuts. Originally legislated in 2019 with different parameters, the cuts were modified in early 2024 to provide greater relief to lower and middle income earners. The key changes that took effect from 1 July 2024 include:
- The rate on income between $18,201 and $45,000 was reduced from 19% to 16%.
- The 32.5% and 37% brackets were consolidated into a single 30% bracket covering income from $45,001 to $135,000.
- The threshold for the 37% rate was lifted from $120,000 to $135,000.
- The threshold for the top 45% rate was lifted from $180,000 to $190,000.
These changes mean that most taxpayers pay less income tax in 2026-27 compared to the previous financial year. Someone earning $60,000 saves approximately $804 in income tax. Someone earning $100,000 saves approximately $2,179. Higher earners above $146,000 also benefit, though the savings are proportionally smaller relative to income at the top end.
Other Notable Updates
- The Medicare levy low-income threshold for singles increased to $23,226, with the shade-in threshold at $29,033.
- The HELP minimum repayment threshold for 2026-27 is $54,435, with the lowest repayment rate at 1%.
- The concessional superannuation contributions cap remains at $30,000, with unused cap amounts able to be carried forward for up to five years if your total super balance is below $500,000.
- The tax-free threshold of $18,200 remains unchanged and continues to benefit all resident individual taxpayers.
Putting It All Together
Income tax affects nearly every financial decision you make, from accepting a job offer to choosing how many hours of overtime to work. The Australian system is progressive by design, ensuring that those who earn more contribute a larger share while protecting low-income earners through the tax-free threshold and offsets like LITO. Our income tax calculator gives you a fast, reliable starting point for the 2026-27 financial year, using the official ATO resident individual rates and a Medicare levy estimate.
Use the calculator to compare scenarios: what happens if you earn a bonus, claim an extra $2,000 in deductions, or move from part-time to full-time work. Understand your marginal rate so you can evaluate the true value of additional income. Remember that the estimate is a guide, not a substitute for a lodged tax return, and that factors like HELP repayments, the Medicare Levy Surcharge, and tax offsets may adjust your final position.
Tax law changes regularly, and individual circumstances vary widely. If your situation involves investment properties, trust distributions, foreign income, or business structures, seek advice from a registered tax agent. For the majority of Australian salary and wage earners, however, understanding the brackets, knowing your deductions, and running the numbers through a calculator is enough to take control of your tax planning with confidence.
