How to Reduce Taxable Income in Australia: Practical Tips

Vania Wang • November 18, 2025

When people ask how to reduce their taxable income in Australia, the answer boils down to two core strategies: boosting your allowable deductions and making smart use of tax-effective structures like superannuation.

The goal is to legally lower the amount of income the Australian Taxation Office (ATO) can tax. This usually involves claiming every single work-related expense you're entitled to or making pre-tax contributions to your super.

Understanding You r Taxable Income

Before diving into the "how," it's crucial to understand what taxable income actually is. It's not just your salary. Think of it as your total assessable income minus any allowable deductions. The final figure is what the ATO uses to calculate how much tax you owe.

So, what’s in your assessable income? More than you might think. It can cover:
  • Employment income (your salary, wages, and any bonuses)
  • Business income
  • Investment returns (interest from savings, share dividends, rental income)
  • Capital gains
From this total, you get to subtract deductions—these are simply the costs you incurred to earn that income. The whole thing is a simple formula that forms the foundation of all tax planning: Assessable Income - Allowable Deductions = Taxable Income.

How Marginal Tax Rates Work
Australia's tax system is 'progressive', which means you don't pay a single flat rate on everything you earn. Your income is divided into brackets, and you only pay the higher rate on the portion of your income that falls into that higher bracket.

For instance, if a tax bracket tops out at $120,000 and you earn $125,000, only that extra $5,000 gets taxed at the higher rate. This is exactly why even a small drop in your taxable income can have a big impact. If you can bring your income down to just under a higher threshold, the savings can be significant.

The key thing to remember is that every dollar you successfully deduct doesn't just lower your taxable income—it saves you tax at your highest marginal rate. If you're in the 32.5% tax bracket, every $100 you claim in deductions is $32.50 back in your pocket.

Government policies can also shake things up. Remember the Low and Middle Income Tax Offset (LMITO)? It provided a direct tax reduction of up to $1,500 for millions of Aussies. When it was removed after the 2021–22 financial year, many people felt the pinch, highlighting how quickly tax liabilities can shift with policy changes. You can dig into how these policies affect different incomes through OECD reports on taxing wages in Australia.


Maximising Your Work-Related Deductions
Claiming every legitimate work-related expense is one of the most direct ways to lower your taxable income in Australia. While most people know the basics, the real wins come from looking beyond the obvious. Even small, consistent claims add up to a significant tax reduction over the year.

The Australian Taxation Office (ATO) has three golden rules for claiming a work-related deduction. To be eligible, an expense must meet all three criteria:
  • You must have spent the money yourself and weren't reimbursed by your employer.
  • The expense must directly relate to earning your income. There has to be a clear link between the cost and your job.
  • You must have a record to prove it, like a receipt, invoice, or bank statement.
These principles apply to everything you might claim, ensuring claims are for genuine work-related costs, not private expenses.
Common But Often Overlooked Deductions

It's easy to claim the standard stuff, but a more thorough approach can uncover a lot more. For instance, a graphic designer paying for their monthly Adobe Creative Cloud subscription can claim that cost. In the same way, a registered nurse can deduct the annual fee for their professional registration with AHPRA. These are direct costs of being able to do their jobs.

Beyond subscriptions and professional fees, think about these other common areas:
  • Vehicle and travel expenses: This covers using your own car for work-related trips, like visiting clients or travelling between different work sites (but not your normal daily commute to and from home).
  • Clothing and laundry: You can claim the cost of buying and cleaning occupation-specific clothing, protective gear, or uniforms that feature your employer's logo.
  • Self-education expenses: If you undertake a course or training that is directly relevant to your current job and is likely to improve your skills, the fees are generally claimable.
  • Tools and equipment: The cost of buying or leasing equipment you need for work—from a mechanic's tools to a specialised laptop for a software developer—is deductible.
The Home Office Advantage
With many Australians working from home, understanding these deductions is crucial. The ATO allows you to claim a portion of your home running expenses, which can make a real difference to your tax bill.

You can claim costs for the hours you work from home, covering things like electricity, gas, internet, and the decline in value of your office furniture. For a full rundown of what you can claim and how to calculate it, check out our guide on claiming work-from-home expenses.

The secret to maximising deductions isn’t about finding loopholes; it's about meticulous record-keeping. Use a dedicated app, a simple spreadsheet, or even just a folder for receipts. When tax time rolls around, you'll have everything ready to go, making it easy to claim what you're rightfully owed without any stress.

At the end of the day, it’s about thinking critically about every dollar you spend to support your job. Did that purchase help you earn your income? If the answer is yes, and you have the receipt, it’s probably a valid deduction that will help lower your taxable income.

Using Super Contributions To Your Advantage
Want to build your retirement savings and cut your tax bill at the same time? Making before-tax contributions to your superannuation is one of the smartest financial moves most working Australians can make.
The strategy is simple but powerful. These contributions, known as concessional contributions, are taxed at a flat rate of just 15% when they enter your super fund. For most people, that’s a significant discount compared to their personal marginal tax rate, which can climb as high as 45%.

You can make these contributions in two main ways:
  • Salary Sacrificing: This is an arrangement with your employer where they direct a portion of your pre-tax salary straight into your super. It’s a fantastic ‘set and forget’ method for regular contributions.
  • Personal Deductible Contributions: You can also make contributions from your own bank account and then claim a tax deduction for that amount when you lodge your tax return. This is ideal for the self-employed or if your employer doesn't offer salary sacrificing.
The Financial Impact of Concessional Contributions
So, how does this actually save you money? Every dollar you contribute this way lowers your taxable income by that exact amount.

Let’s say you earn $100,000 a year and decide to make a $10,000 pre-tax contribution. The ATO will now only assess you on $90,000 of income for that year. It’s an instant reduction in your tax bill.

Super contributions are a cornerstone of long-term tax planning in Australia. For the 2024–25 financial year, you can contribute up to $30,000 concessionally. It's a widely used strategy—the Australian Taxation Office (ATO) reported that Aussies contributed over $130 billion this way in the 2021–22 financial year alone.

The table below shows how a $10,000 salary sacrifice could work at different income levels, giving you a clear picture of the potential tax savings.

Table comparing annual salary, taxable income, tax on contribution, and potential tax saving.

Note: These figures are illustrative and based on 2024–25 tax rates, excluding the Medicare levy. Actual savings depend on individual circumstances.


As you can see, the higher your income, the more valuable this strategy becomes because you're saving tax at a higher marginal rate.

Staying Within The Caps

While this is a great strategy, there are limits. The ATO sets an annual cap on concessional contributions, and exceeding it can trigger extra tax. It’s vital to keep track of all your contributions, including the compulsory super guarantee payments made by your employer.


One important rule to note: high-income earners (those with a combined income and super contributions over $250,000) may face an additional 15% tax on their contributions, known as Division 293 tax.

As the visual shows, a solid tax reduction plan isn't about just one thing; it's about combining different strategies, from claiming work-related expenses to making savvy super contributions.


By consistently putting extra into your super, you're not just paying less tax today—you're building a much healthier nest egg for your future, powered by decades of compounding returns.

Exploring Salary Packaging and Fringe Benefits

Salary packaging, often called salary sacrificing, is one of the smartest ways to lower your taxable income in Australia. The idea is simple: you arrange with your employer to receive less in your take-home pay, and in return, they cover certain personal expenses for you using your pre-tax salary.


Because these costs are paid before tax is calculated, your total taxable income shrinks. For many people, this adds up to significant savings over the year, and it’s not just about super.


What Can You Typically Package?

Every workplace has its own rules, but a few common items pop up in most salary packaging arrangements.

  • A Car via a Novated Lease: This is easily one of the most popular options. A novated lease lets you bundle your car and all its running costs—fuel, insurance, rego, servicing—and pay for it all straight from your pre-tax income.
  • Portable Electronic Devices: Laptops, tablets, and mobile phones that you use mainly for work are often eligible. It’s a fantastic way to fund the tech you need without paying tax on that money first.
  • Other Work-Related Expenses: Think things like self-education courses, professional association fees, or even income protection insurance. Some employers will let you include these in your package too.


The benefit is crystal clear. Let’s say you package a $2,000 laptop. That’s $2,000 instantly removed from your taxable income. If you’re in the 32.5% tax bracket, that’s a direct tax saving of $650 right there.


Understanding Fringe Benefits Tax

Here’s the catch you need to know about. When an employer provides an employee a non-cash benefit like this, it can trigger Fringe Benefits Tax (FBT). This tax is paid by your employer, not you.


However, the cost of that FBT is usually passed back to you within your salary package, so it’s essential to know how it works.

The good news is that some of the best items to package are either exempt from FBT or receive concessional treatment. Work-related laptops, for instance, are often FBT-exempt. If you want to get into the nitty-gritty, we’ve broken down the rules in our guide to Fringe Benefits Tax explained on our blog.


A well-structured salary package ensures that the tax savings you gain are greater than any FBT costs incurred. Always do the maths to confirm the arrangement puts you ahead financially.


Special Benefits for Certain Sectors

For people working in specific industries, the perks of salary packaging get even better. If you work for a public benevolent institution (like many charities) or a public hospital, the government allows for more generous packaging arrangements.

For example, eligible health and charity workers can package up to $9,010 and $15,900 respectively each year on everyday living expenses. This can include things like mortgage payments, rent, or even credit card bills—all FBT-free.


This is a massive advantage that can dramatically boost take-home pay and is a major reason people choose to work in these sectors. If you’re eligible, it’s one of the most powerful tax-reduction tools you’ll find in Australia.


The Smart Way to Time Income and Expenses

When it comes to your tax bill, when you receive income and when you pay for expenses can make a huge difference. It’s a powerful but often overlooked strategy that’s all about timing your moves around the end of the financial year.


Hand pointing at calendar date June 7, with a receipt hanging below.

The idea is pretty straightforward: bring your deductions forward into the current financial year and, if possible, defer receiving income until the next. This simple shift can have a massive impact, especially if your income fluctuates from one year to the next.


Bringing Deductions Forward Before June 30

One of the most effective ways to lower your taxable income is to prepay for deductible expenses before June 30. This allows you to claim the deduction in the current financial year instead of waiting another 12 months.

Think about the costs you can pay in advance. The ATO generally allows prepayments for items where the service period is 12 months or less, such as:

  • Professional Subscriptions and Memberships: Got an annual industry fee? Pay it in June and claim the whole lot this year.
  • Insurance Premiums: You can often prepay for 12 months of income protection or business insurance.
  • Interest on Investment Loans: If you have a loan for an investment property or share portfolio, prepaying the interest for the next year can be a smart move.
  • Work-Related Education: Enrolling and paying for that professional development course before the EOFY locks in the deduction right now.


This tactic is especially useful if you’ve had a particularly high-income year. Those deductions will work harder for you by offsetting income at a higher marginal tax rate.


Deferring Income to the Next Financial Year

On the flip side, sometimes it’s better to delay receiving income until after July 1. This pushes the tax liability into the next financial year, which is a great strategy if you expect your income to be lower then.


A classic example is for contractors or consultants. If you have the flexibility, you could time your invoicing so that a large payment hits your bank account in July instead of June. That simple delay means the income won’t be counted in this year’s tax assessment.


A word of caution: this is about smart timing, not tax evasion. The ATO has clear rules around when income is officially earned. Make sure any deferral lines up with your legal and contractual obligations.


Managing Capital Gains and Losses

Timing is also everything when you’re dealing with investments like shares or property. When you sell an asset for more than you paid, you create a capital gain, and that profit gets added to your taxable income for the year.

If you’ve sold an asset and realised a big gain, you can offset it by selling another asset that’s currently sitting at a loss—all within the same financial year. This is called tax-loss harvesting, and it can help you reduce or even completely wipe out the tax you owe on your gains.


Here’s a quick rundown of these timing strategies to help you see how they fit together.

Getting the timing right on these key financial moves can save you a significant amount of money come tax time. It’s all about planning ahead and making the calendar work for you.


A Few Common Tax Questions Answered

When you start digging into tax deductions and offsets, a lot of questions pop up. Getting the right answers, straight from ATO guidelines, is the only way to feel confident you're legally trimming your taxable income. Here are a few of the most common queries we tackle for clients.


Can I Claim My Travel To and From Work?

This is a big one, and for most people, the answer is no. The daily trip from your home to your primary workplace is considered private travel by the tax office, so those costs aren't deductible.


But there are some important exceptions. The Australian Taxation Office (ATO) will let you claim travel costs if your job requires you to, for example:

  • Travel directly between two different workplaces during your workday.
  • Drive from your main workplace to an alternative one (and then back again).
  • Transport bulky tools or equipment essential for your job, but only if they genuinely can't be stored securely at your workplace.


A classic example is a tradesperson who has to transport heavy ladders and a full set of power tools from their home to various job sites. In that case, the travel is a necessary part of doing the job, not just getting to the job. That's the key distinction.


What’s the Real Difference Between a Tax Deduction and a Tax Offset?

Understanding this is fundamental to smart tax planning. While both will reduce the tax you pay, they work in completely different ways.


A tax deduction reduces your taxable income. The actual dollar value of that deduction depends on your marginal tax rate. A $100 deduction is worth more to someone in the top tax bracket than it is to someone earning a lower income.


On the other hand, a tax offset (sometimes called a tax credit) directly reduces your final tax bill, dollar-for-dollar. A $100 tax offset will cut your tax payable by exactly $100, no matter how much you earn.


Here’s a simple way to think about it: a deduction is like a discount on the price of an item before the total is calculated. An offset is like a voucher you apply to the final bill. Offsets are often designed to give a more even benefit across all income levels.


Do I Really Need to Keep Receipts For Absolutely Everything?

Good records are the foundation of a tax return that won't cause you sleepless nights. For almost every expense you claim, you need solid proof—a receipt, an invoice, or a bank statement—to show the ATO if they ask.


That said, there are a couple of small exceptions. The ATO lets you claim up to $300 total for work-related expenses without receipts, as long as the claims themselves are legitimate. You can also claim laundry expenses up to $150 based on a reasonable estimate ($1 per load for a mixed wash) without written evidence.


But relying on these is not a smart strategy. The best practice, without a doubt, is to keep a digital or physical record of every single work-related purchase you make. That discipline ensures you can confidently claim everything you're entitled to and have the evidence to back it up.

Virtual Chief Financial Officer for Australian Businesses

By Vania Wang • December 4, 2025
Many businesses operate by only looking at historical data from their bookkeeper or accountant. This tells you where you’ve been, but offers little guidance on where you’re going or how to navigate the road ahead. A virtual CFO, or vCFO, acts as your financial co-pilot, focusing on the future. They go beyond basic compliance and tax lodgements to provide the strategic direction needed to make informed decisions that drive growth. The Strategic Partner Your Business Is Missing While an accountant is essential for maintaining accurate records and meeting ATO obligations, a vCFO’s role is fundamentally different—it's about shaping the future financial health of your business. They analyse your financial data to identify opportunities and flag risks before they become significant issues. For Australian businesses, this strategic partnership delivers clear advantages: Actionable Insights: They translate complex financial reports into plain English. Instead of just seeing a profit figure, you’ll understand which products are most profitable, where costs are increasing, and what specific actions you can take to improve performance. Improved Decision-Making: Key decisions—such as hiring new staff, investing in equipment, or adjusting pricing—are no longer based on gut feelings. A vCFO supports these moves with solid data and financial modelling. Sustainable Growth: They help you manage cash flow, position your business for funding, and build a resilient financial foundation for long-term success. A virtual CFO doesn't just manage your finances; they manage your financial future. Their primary goal is to use financial intelligence to help you build a more profitable and stable business, turning historical data into a roadmap for growth. Building Your Financial Roadmap Many business owners seek a vCFO when facing a specific challenge, such as inconsistent cash flow, shrinking profit margins, or preparing the business for sale. A vCFO addresses these issues by creating financial clarity and developing a clear plan. If you want to dive deeper into this process, our guide on crafting a strategic plan as your roadmap to business growth is a great resource. By building accurate forecasts and tracking relevant key performance indicators (KPIs), they provide the visibility needed to navigate economic challenges and seize opportunities. This proactive approach ensures your business is always prepared for what’s next. What a Virtual CFO Actually Does for Your Business Many business owners view finance through two lenses: a bookkeeper for daily transactions and an accountant for tax compliance. Both are critical, but a virtual chief financial officer (vCFO) operates on a strategic level. They are focused on shaping what happens next quarter, next year, and five years from now. A vCFO acts as your strategic guide, translating financial data into clear, actionable intelligence. It’s about moving beyond simply reporting the numbers to explaining what those numbers mean for your future. Moving Beyond Reporting to Strategic Insight A traditional accountant will prepare a profit and loss statement that tells you if you made money. A vCFO takes this further by analysing that P&L to pinpoint exactly which products or services drive your profits and which ones are underperforming. This analysis leads to crucial strategic questions. Should you invest more in your most profitable offering? Is it time to discontinue a low-margin service? A vCFO provides the data-backed confidence to make these decisions. Their forward-looking role includes: Strategic Financial Planning: They help build a long-term financial roadmap aligned with your business goals, ensuring you have the resources to achieve them. Cash Flow Optimisation: This involves proactively managing cash. A vCFO creates detailed cash flow forecasts to identify potential shortfalls months in advance, helping you avoid liquidity issues. Insightful Forecasting and Budgeting: They build dynamic financial models to simulate scenarios. For instance, they can project the financial impact of hiring new staff or investing in major equipment. A simple way to differentiate the roles: A bookkeeper records the game's score. An accountant ensures the score is reported correctly. A virtual CFO is the coach, analysing the play, calling shots, and creating a strategy to win.

Absentee Owner Surcharge Explained: A Guide to Land Tax

By Vania Wang • November 25, 2025
What Is the Absentee Owner Surcharge? The absentee owner surcharge is a state-level tax applied to land owned by individuals, corporations, or trusts classified as 'absentee'. It ensures that owners living abroad contribute to the state services—like roads, emergency services, and public amenities—that help maintain and increase the value of their property. This surcharge is not a federal tax. The rules, rates, and exemptions differ significantly between states like Victoria, New South Wales, and Queensland. The primary goal is to ensure overseas investors contribute fairly to the funding of state infrastructure that underpins their property's value. It also aims to encourage the active use of local land. For any international investor, Australian expat, or trustee holding Australian property, determining your liability is crucial. Whether you must pay the surcharge depends on several factors: Your residency status, including the amount of time you spend in Australia. The ownership structure (individual, company, or trust). The state in which your property is located. Essentially, it's a financial acknowledgement of your investment in a community you are not physically part of for most of the year.

Understanding The Land Tax Threshold

By Vania Wang • November 22, 2025
Your Guide To The Land Tax Threshold For anyone holding investment properties, understanding the land tax threshold is critical for managing your annual costs. It acts as a starting line; you don't begin to incur tax until your portfolio's total land value crosses that state-specific point. This state-based tax is calculated solely on the unimproved value of your land. This is a crucial detail. It means the state revenue office disregards the value of any buildings, landscaping, or other structures on the property. It’s the land itself, not the dwelling on it, that is taxed. This is why a modest house on a large, valuable block in a sought-after suburb could attract a much higher land tax bill than a brand-new luxury apartment that occupies a very small land footprint. The visual below illustrates this point, showing how the assessment focuses on the land's value alone. This concept is the foundation for how the land tax threshold is applied to your portfolio. It’s all about the value of the underlying land. Why Does This Tax Exist? At its core, land tax is a significant source of revenue for state and territory governments. It helps fund essential public services that benefit the entire community, such as schools, hospitals, roads, and emergency services. The system is specifically designed to apply to those who own land as an investment, which is why your principal place of residence is almost always exempt. The land tax framework is built on a few key principles: Progressive Taxation: The more valuable your total land holdings are, the higher the rate of tax you will pay. State-Based System: This is a critical point. Each state and territory sets its own rules, rates, and land tax threshold. There is no single national system. Aggregation: All the taxable land you own within a single state is added together to determine if you’ve crossed the threshold for that jurisdiction. Because it's a state-based system, an investor with properties in both New South Wales and Victoria is assessed separately in each state. This means they can benefit from two different tax-free thresholds. Effective tax planning is essential for investors, just as it is for small business owners who need to stay current with the latest ATO tips for small business . How Land tax Thresholds Differ Across Australia If you own investment properties across Australia, you cannot view land tax as a single, national rule. Land tax is a state-based system, meaning every state and territory operates under its own distinct set of regulations. This is a critical point for any investor to grasp. A property portfolio with a specific land value in New South Wales could face a completely different tax bill compared to an identical portfolio in Queensland. The differences are not minor. Each state sets its own land tax threshold —the value your unimproved land must reach before the tax applies. Additionally, they set their own tax rates, which typically increase as your land value grows.
