What Expenses Can I Claim on Tax? A Guide for Australians

So, what expenses can you actually claim on tax? The short answer in Australia is pretty simple: you can claim expenses you paid for that are directly related to earning your income. Of course, you need the records to prove it. This opens the door to a huge range of costs, from home office bills and car use to professional subscriptions and the tools of your trade.

Which year? This guide covers the rules for your 2025–26 return. From 1 July 2026 (your 2026–27 return), a standard deduction of up to $1,000 for work-related expenses applies automatically. Work-related expenses you claim reduce it dollar for dollar, while union fees, gifts, tax agent fees and income protection premiums are claimed on top.

Your Quick Guide to Claimable Tax Expenses

Getting your head around what you're entitled to is the first step to making the most of your tax refund. While the Australian Taxation Office (ATO) provides clear guidelines, let's be honest—it can feel like navigating a maze. The secret is to break down all your potential claims into simple, manageable categories. Think of your tax deductions as legitimate, work-related costs that chip away at your taxable income. The lower your taxable income drops, the less tax you owe, which very often translates into a bigger refund in your pocket.

Common Tax Deduction Categories at a Glance

To get you started, we've put together a quick summary of the most common work-related expenses people claim on their Australian tax returns. Use this list as a handy reference to get a feel for the main categories before we dig into the nitty-gritty rules for each one.

• Vehicle and travel: fuel, maintenance, registration, insurance and travel for work-related trips. You must use either the cents per kilometre or logbook method to calculate your claim.
• Home office: electricity, gas, internet, phone bills, stationery and the decline in value of your computer. The claim must relate to the hours you work from home.
• Clothing and laundry: occupation-specific clothing, protective gear, or a compulsory uniform with your employer's logo. Conventional clothing, even if you only wear it for work, is not claimable.
• Tools and equipment: the cost or decline in value of tools, technology and equipment you need for your job. Apportionment is required if you also use the item for personal purposes.
• Self-education: course fees, textbooks and stationery for study directly related to your current job. The study must maintain or improve the skills you need for your current job, or be likely to increase your income from it.
• Other deductions: union fees, professional subscriptions, tax agent fees, gifts to deductible gift recipients and income protection insurance. These are often overlooked but can add real value to your return.

This list gives you a clear roadmap for spotting potential claims. Once you're familiar with these categories, you can start thinking more critically about your spending all year round. Just remember the golden rule: if you spent money to earn your income, it’s always worth investigating whether you can claim it.

The Three Golden Rules for Tax Deductions

Before we start digging into specific expense categories, we need to get our heads around the fundamental framework the Australian Taxation Office (ATO) uses. I like to think of every potential claim as needing to pass through three checkpoints. If an expense stumbles at even one of these, it’s not going to be a valid deduction. Mastering these three golden rules is the absolute key to confidently answering the question, "what expenses can I claim on tax?" for almost any situation you'll ever face. Let's break them down.

Rule 1: You Paid for It Yourself

The first rule is as straightforward as they come:

you must have spent the money yourself. This means the cost came directly out of your own pocket, and critically, you weren't paid back for it by your employer or anyone else. For example, if your company pays for your professional association fees directly, you can't claim a thing. The same goes if they reimburse you for the full cost. But, if they only reimburse you for half the cost, you can absolutely claim the portion you personally paid for. An allowance is different: you include it as income, and you can claim the work expenses it was meant to cover, as long as you actually spent the money and have records. It all comes down to who was ultimately left out of pocket.

Rule 2: The Expense Directly Relates to Your Income

This is the big one—the most critical and most misunderstood rule of all. The expense must have a direct connection, or "nexus," to earning your income. It isn't enough for an item to be vaguely helpful or convenient; it has to be a necessary part of doing your job. Here’s an analogy I use with my clients: a professional chef can definitely claim the cost of their high-quality knives. Those knives are essential tools used directly in the process of making food, which is how they earn their living. No question. However, that same chef couldn't claim a new designer watch, even if they argue they use it to time dishes. While it might be useful, the watch is primarily a private expense, and a simple kitchen timer would do the job just as well. The direct link to generating income just isn't strong enough for the ATO.

The core question the ATO always asks is: "Did you incur this expense in the course of gaining or producing your assessable income?" If the answer isn't a clear and immediate "yes," the claim is on shaky ground.

This principle is what separates a genuine work expense from a personal cost that happens to have some minor work benefit.

Rule 3: You Have a Record to Prove It

The final checkpoint is all about proof. If you can’t prove you spent the money and what you spent it on, you can't claim it. This is what we call your substantiation requirement. So, what counts as a valid record?

• Receipts or tax invoices are the gold standard. They need to show the supplier, date, cost, and exactly what the goods or services were.
• Bank or credit card statements can work, but only if they clearly identify the specific expense.
• Logbooks or diaries are non-negotiable for tracking the work-related use of things like your car or phone.

Without these records, your claim has no leg to stand on if the ATO ever decides to ask a few questions. This brings us to a vital concept called apportionment. When an expense is used for both work and private purposes—like a mobile phone or your home internet—you can only claim the work-related portion. To do this, you must have a reasonable basis for calculating that percentage, like a detailed logbook or diary. This ensures you're only claiming the part that directly helped you earn your income, bringing you right back in line with Golden Rule #2.

Unpacking Your Work-Related Expenses

Alright, now that you’ve got the three golden rules down, let’s get to the good stuff. This is where the theory hits the road and you start identifying the specific, high-value claims that can seriously fatten up your tax refund. The question of "what expenses can I claim on tax?" gets a lot simpler when you start thinking in categories. Let's dive into the most common work-related deductions you're likely to encounter, complete with real-world examples, straightforward explanations, and exactly what paperwork the ATO wants to see.

Vehicle and Travel Expenses

For a huge number of Aussies, their car is basically a mobile office. If you're using your personal vehicle for work—think driving to see clients, heading to a meeting at a different office, or travelling between two separate jobs—you can almost certainly claim a deduction for it. Here’s the big one to remember: driving from your home to your main workplace and back again each day is just your regular commute. It’s considered private travel and is not claimable. The exceptions are few and far between, like if your boss makes you transport bulky tools that you can’t safely leave at the worksite. You’ve got two ways to calculate your claim:

1. Cents per Kilometre Method: This is the no-fuss option. You claim a set rate for every single business kilometre you drive, capped at 5,000 kilometres per car, per year. For 2025–26 (and 2024–25) the rate is 88 cents per kilometre, rising to 91 cents for 2026–27. You don't need a shoebox full of fuel receipts, but you do need to show the ATO how you worked out the kilometres, like with a diary of your work trips.
2. Logbook Method: This one demands more from you in terms of record-keeping, but it can lead to a much bigger tax deduction, especially if you drive a lot for work. You need to keep a detailed logbook for 12 weeks straight to work out your work-use percentage. Once you have that magic number, you can claim that percentage of all your car's running costs—fuel, insurance, rego, servicing, and even the car's depreciation.

Picking the right method is absolutely crucial. For a much deeper dive into which one suits you, check out our complete guide on claiming work-related car expenses.

Home Office Expenses

Working from home has become the new normal for many, whether it's full-time or just a couple of days a week. This means you're definitely paying for things that are directly helping you earn your income, and those costs are claimable. For 2025–26, the ATO gives you two ways to calculate this:

• Fixed Rate Method: This is the shortcut. You can claim 70 cents for every hour you work from home (the rate for 2024–25 and 2025–26). This rate covers your energy (electricity and gas), internet, mobile and home phone costs, plus stationery and computer consumables, so you can't claim those separately. You need a record of every hour you worked from home during the year, like a timesheet, roster or diary, and at least one bill for each type of expense the rate covers.
• Actual Cost Method: The more detailed approach. Here, you calculate the work-related slice of every single home office expense separately. This means keeping records of all your bills and working out the percentage you used for work, such as the hours you used your equipment, or the floor area of your work space for heating, cooling and lighting.

A key point here: no matter which method you use, you can still make a separate claim for the depreciation (decline in value) of big-ticket items like your work laptop, office desk, and printer. You just need to calculate the work-related portion.

Clothing and Laundry Expenses

This is easily one of the most misunderstood categories. You can't just claim your nice new shirt because you wear it to the office. To be deductible, the clothing has to fit neatly into one of three very specific boxes:

1. Protective Clothing: This is gear that literally protects you from getting sick or hurt on the job. Think steel-capped boots, high-vis vests, or non-slip shoes for a kitchen.
2. Occupation-Specific Clothing: These are items that aren't everyday clothes but are uniquely tied to your profession, like a chef's chequered pants or a nurse's scrubs.
3. Compulsory Uniform: This is a uniform your employer insists you wear, and it has to clearly identify you as part of the company, usually with a logo stitched on.

If your work gear ticks one of those boxes, you can also claim the cost of washing it. The ATO has a standard rate of $1 per load if it's a wash of only work clothes, or 50 cents per load if you mix them in with your regular laundry.

Tools and Equipment

Bought tools or equipment to do your job? You can claim some or all of that cost back. How you claim it all comes down to the price tag.

• For anything that costs $300 or less (and isn't part of a set that together costs more than $300), you get an immediate, full deduction. You claim the entire cost in the same financial year you bought it.
• For items over $300, you can't claim it all at once. Instead, you claim its decline in value, or depreciation, over its effective lifespan.

This is a critical distinction for bigger buys like a new work laptop, specialised machinery, or expensive tech gear. And just like everything else, if you use that new tool for personal stuff too, you have to apportion the cost and only claim the percentage you used for work. Getting these categories right is how you maximise your tax refund.

Uncovering Less Obvious Tax Deductions

Once you've got a handle on the big-ticket items like your car, home office, and work clothes, it's time to dig a little deeper. So many people leave good money on the table simply because they stop at the most obvious claims. Thinking beyond the basics is where you can really start to boost your refund. These less common deductions often hide in plain sight, covering costs for professional development, memberships, and even the fee you pay to get your tax return done. Let's shine a light on these often-forgotten opportunities.

There are always conditions. For things like uniforms, travel, and home office costs, you need clear proof that the expense has a direct connection to how you earn your income.

Maximising Your Self-Education Expenses

Investing in your own skills is one of the smartest career moves you can make, and the ATO often gives you a tax break for it. The key is that any self-education course you claim must have a direct link to your current job. The course doesn't have to lead to a formal qualification, but it must tick at least one of these boxes:

• It maintains or improves the specific skills you need for your current role.
• It's likely to lead to a pay rise in your current job.

This means you can’t claim a course that's only vaguely related to what you do, or one you’re taking to switch careers entirely. For instance, a real estate agent doing a Certificate IV in Property Services can claim those costs. But if that same agent decided to study nursing, those fees wouldn't be deductible.

The core test is relevance to your current income-earning activities. If you can prove that direct link, a wide range of costs become deductible, including course fees, textbooks, stationery, and even travel to your place of education. You also no longer reduce your claim by $250: that rule was removed for expenses incurred from 1 July 2022.

Other Work-Related Deductions You Might Miss

This is a fantastic catch-all category for a bunch of smaller, but still valuable, work expenses that don't quite fit anywhere else. It’s a goldmine if you’re trying to make sure your tax return is as thorough as possible. Common items you can claim here include:

• Union and professional association fees: Your annual fees for union membership or professional bodies are fully deductible.
• Professional subscriptions and journals: The cost of industry magazines, online news subscriptions, or other publications directly tied to your job is claimable.
• Work-related phone and internet costs: You can claim the work-related portion of your personal mobile and home internet bills. Just be sure to keep a diary for a typical four-week period to figure out a reasonable percentage.
• Gifts to deductible gift recipients (DGRs): You can claim gifts of money to a DGR, with no minimum amount for gifts made from 1 July 2024, as long as you didn't get anything in return. Not every charity is a DGR, so check before you give, and keep the receipt.
• Income protection insurance: Premiums for a policy you hold outside super that replaces your salary or wages are deductible. Premiums paid through your super fund, and life, trauma or critical illness cover, aren't.

The Cost of Managing Your Tax Affairs

Here’s one deduction nearly every single taxpayer can claim. Fees you pay a registered tax agent (like us!) for preparing and lodging your tax return are deductible in the income year you incur them, so the fee for last year's return is usually claimed on this year’s return. This also covers the cost of travel to see your tax agent and fees for tax advice from a registered tax agent during the year. One change to note: interest the ATO charges on late payments or amended assessments (the general interest charge and shortfall interest charge) can't be claimed if it was incurred on or after 1 July 2025. From 2026–27, tax agent fees are claimed on top of the $1,000 standard deduction rather than reducing it. It’s a simple but powerful deduction that many people forget.

Mastering the Art of Record Keeping

A tax deduction is only as good as the proof you have to back it up. Without solid evidence, even the most legitimate claim can be knocked back by the Australian Taxation Office (ATO). This is where good record keeping transforms from a tedious chore into your most powerful tool for maximising your refund. Think of it this way: every claim you make is a statement, and your records are the evidence that proves it's true. This process, known as substantiation, is non-negotiable. It’s your best defence against an audit and the key to lodging your tax return with complete confidence.

What Counts as a Valid Record

Forget the old shoebox overflowing with faded receipts. These days, a valid record can take many forms, and the ATO accepts a range of digital and paper documents as proof of purchase and work-related use. Your goal is to build an audit-proof file for every single expense. The essential records include:

• Tax Invoices or Receipts showing the supplier's name, the amount, the date, and what you actually bought.
• Bank or Credit Card Statements that clearly identify the expense and can be linked back to a specific invoice.
• Logbooks to track the business use percentage of assets like your car or phone over a set period.
• Diaries or Digital Calendars to note down hours worked from home or details of work-related travel.

Using digital tools can make this process almost effortless. Simple apps or even a dedicated folder in your cloud storage can help you snap, save, and sort receipts the moment you get them.

The golden rule is simple: if the ATO asked about an expense, could your records show a clear, undeniable link between the money you spent and how it helped you earn your income? If the answer is yes, you're on the right track.

The Five-Year Rule and Key Exceptions

So, once you have your records, how long do you need to keep them? The ATO is crystal clear on this: you must hold onto your records for five years from the date you lodge your tax return. This five-year window gives them plenty of time to review your claims if they ever need to. However, there are a couple of important exceptions designed to simplify things for taxpayers with minimal claims. You don't need to provide written evidence for:

1. Total work expenses up to $300 (2025–26 and earlier): if all your work-related deductions added up to $300 or less, you didn't need receipts. You still had to have spent the money and be able to explain how you worked out the claim. From 2026–27 this is replaced by a standard deduction of up to $1,000.
2. Laundry up to $150 (2025–26 and earlier): you could claim laundry up to this amount without receipts, as long as the clothing was a deductible uniform, protective gear or occupation-specific item. From 2026–27 you need a record of your loads and evidence you paid.

These exceptions are handy, but they aren't a free pass to make things up. For a complete overview of your obligations, our guide on what tax records you need to keep offers a deeper dive into this crucial topic. Adopting good habits year-round makes tax time a simple exercise in reporting, not a stressful scramble for proof.

Common Tax Deduction Mistakes to Avoid

Knowing what you can't claim is every bit as important as knowing what you can. The rules around tax-deductible expenses can be a minefield, and a few common errors trip people up year after year. Making an incorrect claim—even if it's an honest mistake—is a surefire way to attract unwanted attention from the Australian Taxation Office (ATO). Think of this section as your defence against the most frequent mistakes and persistent myths. By learning to spot these pitfalls, you can lodge your return with total confidence, knowing your claims are accurate, compliant, and audit-proof.

Debunking Persistent Tax Myths

One of the most stubborn misconceptions out there is the idea of a standard, "automatic" deduction. A surprising number of people believe they can claim a flat amount for work expenses without actually spending a cent.

Myth: "Everyone can claim a standard $300 deduction, no questions asked." Reality: for 2025–26 and earlier, $300 was only the limit for claiming without receipts, and you still had to have spent the money. From 2026–27 there is a standard deduction, but it's up to $1,000, and taking it means your other work-related expense claims reduce it dollar for dollar. See what you can claim without receipts.

This isn't free money. For 2025–26 and earlier, if you didn't spend it, you can't claim it. From 2026–27 the standard deduction is applied automatically, but any work expenses you claim instead must be real and backed by written evidence.

Expenses That Are Almost Never Claimable

Beyond the myths, certain personal expenses are consistently knocked back by the ATO, no matter how much you might argue they help you at work. These are considered private in nature and fail the all-important "direct connection" test. Be sure to avoid claiming these common non-deductible costs:

• Your Daily Commute: The trip between your home and your main place of work is considered private travel. It doesn't matter how far you live or if you answer a few emails on the train; it’s not claimable.
• Conventional Clothing: A standard business suit, plain office attire, or regular shoes are not deductible. This holds true even if your boss requires you to wear them and you only ever use them for work. Unless it's a compulsory uniform with a logo, protective gear, or something occupation-specific, you can't claim it.
• Personal Grooming: Haircuts, cosmetics, and general hygiene products are always considered private expenses. It makes no difference if you're in a client-facing role that demands a polished appearance.
• Childcare Costs: The cost of childcare is not considered a work-related expense and cannot be claimed, even if it's essential for you to be able to go to work in the first place.

Steering clear of these common blunders is crucial for keeping your tax affairs in order. It ensures every deduction you claim is legitimate, protecting you from potential penalties and helping you build a strong, accurate tax history.
