Work-Related Expense Deductions in Australia 2026-27

Tax time in Australia has a habit of turning a shoebox of receipts into a guessing game. Most PAYG employees and sole traders know they can claim something for the money they spend doing their job, but far fewer know exactly where the line sits between a genuine work related expense deduction and a claim that bounces back from the ATO.

This guide works through what the ATO actually says about work related expense deductions heading into the 2026-27 income year, how the deduction categories fit together, and how to keep records that hold up if someone asks. It is general information only. It is not tax advice and it is not written by a registered tax agent, so treat it as a way to ask better questions rather than a final answer.

What Makes an Expense Deductible in the First Place

The starting point is simpler than most people expect. The ATO states that an employee may be able to claim deductions for work-related expenses they incurred while performing their job. MyBudget describes a work-related deduction as something you paid for yourself that directly relates to your income. Both descriptions point the same way: the money came out of your pocket, and the reason you spent it connects to how you earn.

The ATO has also highlighted one golden rule in its own social posts. You must have spent the money yourself and not been reimbursed. If your employer pays you back for a pair of boots, a phone bill or a course fee, that expense is gone as a deduction. The same post warns that you cannot simply copy and paste last year's claims into this year's return, because your job, your tools and your hours may all have shifted since then.

The Five Categories the ATO Groups Work Expenses Into

The ATO sorts work-related deductions into five broad buckets, and knowing which bucket you are standing in makes the rules much easier to follow.

• Cars, transport and travel. The ATO provides a calculator to work out the deduction that can be claimed for work-related car expenses for eligible vehicles, which is worth running before you estimate anything by feel.
• Tools, computers and items used for work. Equipment you buy and use on the job lands here, and this is where mixed work and private use usually shows up.
• Clothes and items worn at work. Clothing and items worn on the job sit in this category, and it is one of the areas where the ATO applies close attention.
• Working from home. Running costs from doing your job at home belong here, and they need a consistent way of working out the work portion rather than a rough guess.
• Education, training and seminars. The ATO treats this as its own category and publishes dedicated guidance on it.

Phone and internet expenses are a common addition on top of those categories. H&R Block lists work-related phone and internet usage among the deductions an office worker may be able to claim, which makes sense given how much of a typical desk job now happens through a screen.

Official Guidance Versus Commercial Checklists

Search for work related expense deductions and you will land on two very different kinds of page: official ATO material and commercial summaries from budget services, accountancy firms and tax preparation companies. Both can be useful, but they are not the same thing.

One caution worth remembering: the ATO has not endorsed those third-party checklists or calculators. Only the ATO's own tools carry that weight, so treat commercial summaries as a prompt for questions rather than a final ruling.

Occupation Matters More Than Most People Think

The ATO does not treat every worker the same, and it does not expect you to guess. It publishes occupation-specific guidance, including a guide for building and construction employees that covers income, allowances and claiming deductions for work-related expenses. That page carries a 2026 date, which makes it a useful reference point for tradies and site workers sorting out what belongs in their return.

At the other end of the spectrum, H&R Block publishes an office worker deduction checklist. The two documents are not in conflict. They simply reflect the reality that a carpenter and an administration officer spend money in completely different ways to earn their income, even though the underlying deduction principles come from the same rulebook.

Work Use Versus Private Use

This is where a lot of claims quietly fall apart. Nanak Accountants notes that if an expense serves both work and private purposes, only the work-related portion might be eligible for a deduction, and points to vehicle and travel expenses as a clear example.

The practical version of that rule is straightforward. A phone used for work calls and weekend scrolling is not a work phone, it is a shared phone, and the claim should reflect the split. The same thinking applies to a laptop, a vehicle, a home internet connection or a set of tools. Keep a written record of your work use over a representative period, then apply that proportion consistently. A reasonable estimate you can explain is worth far more than a round number you cannot.

Records That Hold Up When Someone Asks

Record keeping is where the ATO's patience runs out fastest. An expense you genuinely incurred but cannot demonstrate is difficult to defend, so the aim is to be able to show three things: that you paid, that the expense relates to your work, and how you calculated the work portion.

• Keep receipts, invoices or bank statements that show the payment.
• Note the work purpose in your own words while you still remember it.
• Write down how you split work and private use, and the period you based it on.
• Store it all somewhere you can find it at lodgment time rather than reconstructing it from memory.

Some of the guidance floating around online was written for earlier income years, including an ATO myTax page dated 2024 and a commercial blog from 2025. Rules do shift, so check the current-year ATO material for your own situation before you rely on an older page.

Where a Tracker Actually Helps

The shoebox problem is not really a tax problem, it is a filing problem. Expenses that go unrecorded through the year tend to go unclaimed at the end of it, which is exactly the gap Lodgya was built to close. It is a browser-based income and expense record-keeping tool for Australian tax, and the personal tracker is set up around deductions and receipts, including work-related expenses.

Whether you use a tracker, a spreadsheet or a folder on your kitchen bench matters less than consistency. What matters is that by the time you sit down to lodge, your work related expense deductions are already written down, sorted and defensible.

Five Mistakes Worth Avoiding

1. Copying last year's claims without checking whether your job has changed, which the ATO has warned against directly.
2. Claiming the full cost of something you also use privately instead of the work-related portion.
3. Claiming an expense your employer has already reimbursed you for.
4. Relying on an older ATO page or a 2025 blog post for 2026-27 rules.
5. Leaving record keeping until lodgment, when the details are hardest to remember.

None of these mistakes are unusual, and none are impossible to fix. They mostly come down to treating deductions as a year-round habit rather than a single frantic evening in July.

Frequently Asked Questions

Do I need receipts for every work-related expense I claim?

You need to be able to show that you spent the money yourself, that you were not reimbursed, and how the expense connects to your work. That usually means keeping receipts or bank statements plus a written note explaining the work purpose and how you worked out any work-use portion. Without records, a genuine expense becomes very hard to defend if the ATO asks questions later.

Can I claim something I use for both work and personal purposes?

Possibly, but usually only for the work-related share. Nanak Accountants makes the point that where an expense serves both work and private purposes, only the work-related portion might be eligible, using vehicle and travel expenses as an example. So a shared phone, laptop or car should be apportioned rather than claimed in full, with a record of how you arrived at that split.

What can office workers claim on their tax return?

The ATO categories apply to desk jobs too, covering working from home, tools and equipment used for work, and education or training connected to your role. H&R Block also lists work-related phone and internet usage among the deductions an office worker may claim. Because so much office work now happens away from the office, the work-use split matters more than ever.

How do I work out a claim for car expenses?

The ATO publishes a calculator designed to work out the deduction that can be claimed for work-related car expenses for eligible vehicles. Using it before you lodge gives you a defensible figure rather than an estimate, and it helps confirm your vehicle and usage actually qualify. If your situation is complicated, check the current ATO guidance or speak with a registered tax agent.

Are the deduction checklists I find online reliable?

They are a reasonable starting point and can jog your memory about expenses you had forgotten. What they are not is official. The ATO has not endorsed third-party checklists or calculators, and some of that material was written for earlier income years. Use commercial summaries to build your list, then confirm each claim against current ATO guidance before you lodge.

Work related expense deductions reward preparation far more than cleverness. Know which category your expense belongs to, keep a record of what you paid and why, split work from private use honestly, and check the current ATO material rather than a page written for a previous income year. Do that and the shoebox stops being a source of anxiety, and starts being the reason your refund looks the way it does.
