If you’ve ever typed “what can I claim on tax” into Google at 11 pm before lodgement, you’re in good company. It’s one of the most searched financial questions in Australia and also one of the most misunderstood.
This guide answers it properly. Not a vague list of categories. Not a redirect to the ATO. The actual rules, the common mistakes, and the things most people get wrong, including the biggest one, which is thinking a tax write-off means something is free.
Whether you’re an employee, a sole trader, or a small business owner in Victoria, here’s what you need to know.
What Is a Tax Deduction?
Here’s the version that trips people up: you claim $5,000 in work-related expenses and expect $5,000 back. That’s not how the calculation works.
A deduction reduces the income figure on which your tax is calculated, not the tax bill itself. So if you earned $80,000 for the year and had $5,000 in legitimate deductions, the ATO taxes you on $75,000. What you actually recover is the tax that would have been charged on that $5,000 slice of income. At a 32.5% marginal rate, that’s somewhere around $1,600. At 19%, closer to $950.
Worth claiming? Absolutely. A refund on your actual tax rate. Not the amount you spent.
Deductions vs Offsets vs Credits
A deduction works before the tax calculation happens. Spend $3,000 on legitimate work-related expenses, and $3,000 comes off your taxable income. If your marginal rate sits around 32.5%, you save roughly $975 in tax. The deduction doesn’t appear on your bill; it changes the income figure the bill is built from.
Offsets work after. If your tax liability comes to $4,000 and you qualify for a $500 offset, you pay $3,500. The bracket you’re in doesn’t affect it; offsets reduce the final figure directly. The Low Income Tax Offset (LITO) works this way, as does the Seniors and Pensioners Tax Offset (SAPTO). The Low and Middle Income Tax Offset is a different story; it wound up after 2021-22 and doesn’t apply to current returns, though it still surfaces in older guides.
Franking credits, sometimes called imputation credits, work similarly to offsets in their effect on your bill. They come into play when you receive dividends from a company that’s already paid corporate tax on those profits. The credit represents the tax already paid at the company level, so you’re not assessed on the same income twice. For small business owners with investment income, these credits can make a meaningful difference to the final liability.
The practical difference across all three is that deductions change what gets taxed. Offsets and credits change what you owe after the calculation runs.
What Can I Claim on Tax? The Core Categories
For a deduction to be valid under ATO rules, three conditions must be met:
- You spent the money yourself and weren’t reimbursed
- The expense directly relates to earning your income
- You can prove it with appropriate records
With that in mind, here are the main categories of claimable work-related expenses:
Work-related travel
Travel costs are claimable when you’re travelling for work, but the definition of “for work” is narrower than most people assume.
Getting from home to your usual workplace doesn’t qualify. The ATO treats that as a personal expense, and the length of the commute doesn’t change it. Where deductions do apply: travel between two workplaces, client visits, industry events, and work-related interstate trips. Flights, accommodation, parking, and tolls are all on the table when the trip is genuinely work-related, and you’re funding it yourself.
For your own vehicle, there are two calculation methods. The cents-per-kilometre method covers up to 5,000 km per year at the ATO’s set rate, currently in the ballpark of 85 to 90 cents per kilometre depending on the financial year. No logbook required for this method, but you’ll need to account for how you got to the figure and show the trips were work-related. The logbook method captures the full cost of running the vehicle, fuel, insurance, registration, and depreciation, but requires a logbook covering at least 12 consecutive weeks to establish the business-use percentage. For most sole traders with significant vehicle use, the logbook method returns a higher figure.
Work uniforms and equipment
Occupation-specific clothing, tools, and equipment are used directly to earn income. A branded work shirt with a logo is claimable. Generic clothing you could wear anywhere else is not. Equipment used partly for work and partly privately can be claimed at the work-use percentage.
Work from home tax deductions
The ATO’s fixed rate method allows a set amount per hour for every hour you work from home, currently in the range of 67 cents, covering electricity, internet, and phone costs. If you use this method, those costs are already factored in; claiming them separately on top of it is one of the most common WFH errors the ATO picks up on.
The actual cost method does what it says: you claim real expenses, at the real amount, with real records to back them. That means a representative four-week diary showing your work pattern, receipts for the costs you’re claiming, and a clear basis for any apportionment between work and personal use. More administration, but for some setups, it returns a higher figure than the fixed rate.
Neither method covers rent, mortgage interest, or household consumables. The coffee you drink while working from home stays personal regardless of the method.
These rates do get reviewed. Before you calculate anything, check the ATO’s current published rate rather than relying on a figure from a previous year’s return.
Self-education and professional development
Courses, memberships, and subscriptions are deductible when they connect directly to the work you’re doing now. The ATO’s position on this is fairly consistent: the training has to maintain or improve skills in your current role, not qualify you for a different one.
A project manager studying advanced Excel for their existing role, claimable. The same person is doing a nursing degree because they’re considering a career change, not claimable, regardless of how the course is framed. The connection to current income-earning activity is what the ATO tests, not whether the course sounds work-adjacent.
Union fees, professional association memberships, and industry body subscriptions follow the same logic. If the membership relates to the work you’re actually doing, it qualifies. If it’s aspirational, it doesn’t.
Gifts and donations
Donations made to organisations registered as Deductible Gift Recipients (DGRs) are claimable. The gift must be money or property, not time or effort. A GoFundMe for someone’s personal hardship is generally not claimable. A donation to a registered charity’s DGR fund is.
Cost of managing tax affairs
Fees paid to a registered BAS agent or tax agent, including bookkeeping costs that relate to your tax affairs, are deductible. This applies even if the fee covers the prior year’s return.
Personal super contributions
If you’ve made voluntary after-tax super contributions and want to claim them as a deduction, you must lodge a Notice of Intent to Claim with your super fund before lodging your return. This applies to employees, sole traders, and self-employed individuals.
Investments
Interest on loans used to generate investment income, fees for investment advice directly related to your investments, and certain management costs can be deductible. The line between claimable investment expenses and non-claimable personal financial planning fees can be complex, so this is worth reviewing with a bookkeeper or registered tax agent.
What Can I Claim on Tax Without Receipts?
The question most guides sidestep: what can you actually claim on tax without receipts?
The ATO has specific thresholds rather than a blanket rule. Work-related expenses under $300 in total can be claimed without written evidence, but that’s a combined ceiling across all claims in that category, not $300 per item. For laundry and uniform costs specifically, the limit sits around $150 before receipts or diary records become required.
Vehicle claims under the cents-per-kilometre method sit outside this. You can claim up to 5,000 km without a logbook, provided you can show the basis for your calculation and the purpose of the travel. For very small individual expenses under $10, a diary record covering the date, amount and nature of the purchase can substitute for a receipt, up to around $200 in total across those small expenses.
Past those thresholds, written evidence is expected. Bank statements, invoices, receipts, or something that existed at the time of the transaction. A rough estimate reconstructed at tax time isn’t documentation. The ATO’s position on tax deductions without receipts is that the burden of proof sits with the person making the claim, and that position hasn’t shifted.
Instant Asset Write-Off: Current Position
Through 2024-25, small businesses with aggregated turnover under $10 million could immediately deduct eligible assets under $20,000 rather than depreciating them gradually. The threshold applied per asset, not as a combined limit, and covered both new and second-hand items as long as they were in use or ready to use before 30 June 2025.
That measure has now lapsed.
From 1 July 2025, the immediate deduction threshold dropped back significantly for most businesses. The exact figure depends on whether any subsequent legislation moved it again, and given how frequently this provision has changed, that’s a genuine uncertainty rather than a boilerplate caveat. If you’re factoring the write-off into a purchasing decision for the current financial year, the ATO’s small business depreciation page has the current position. A registered tax agent can confirm whether any recent changes apply to your turnover bracket before you commit.
Assets that don’t meet the current threshold go into the simplified depreciation pool: 15% in year one, 30% each year after that.
What the ATO Flags: Common Over-Claiming Mistakes
This is where real money is lost, either in a review or in penalties, and it’s an area most competitors don’t cover directly. If you want a broader picture of what triggers ATO scrutiny for Melbourne businesses, the ATO audit red flags guide covers the full list.
Claiming private use as work use
Using your laptop 60% for work and 40% for personal use means you can claim 60% of the cost, not 100%. The same logic applies to phone bills, cars, and home office expenses. The ATO is specifically alert to 100% work-use claims on items that are obviously used privately.
Watches
Just because you check work emails on your smartwatch doesn’t make it claimable. Watches are considered personal items. The only exception is a watch with a specific work function that isn’t available in an ordinary timepiece, a nurse’s fob watch for example. A standard smartwatch doesn’t qualify, regardless of how often you use it for work.
Grooming and cosmetics
Haircuts, makeup, and personal grooming are not deductible. Even if your appearance directly affects your income. Even if your employer requires a certain standard. The ATO has consistently held that these are personal expenses.
Double-dipping on work-from-home expenses
If you’re using the fixed rate method, you cannot separately claim your phone, internet, or electricity costs on top of it. They’re already included in the rate. This is one of the most common WFH errors the ATO identifies.
Claiming entertainment
Work functions, client lunches, and team dinners are generally not deductible for employees. Fringe benefits tax rules may apply differently for businesses, but as an employee, attending a compulsory work event doesn’t make your expenses claimable.
Claiming commuting costs
Travel from home to your regular place of work is not deductible, full stop. It doesn’t matter how far you travel, how early you start, or whether you carry tools. The only exceptions involve transporting bulky equipment with no secure storage at work or travelling between two separate workplaces.
The pattern the ATO looks for is claims that seem inconsistent with the occupation, 100% work-use rates on dual-use items, and deductions that appear without corresponding income. Getting this wrong isn’t just a refund issue. It can attract penalties and interest.
Sole Trader and Self-Employed Tax Deductions
If you’re self-employed or operating as a sole trader in Victoria, the deductions framework is broader than what applies to employees, and the record-keeping requirements are more demanding. The growing your sole trader business guide covers the broader financial picture if you’re at that stage.
In addition to work-related expenses, sole traders can generally claim:
Business operating costs
Rent for business premises, utilities used in the business, business insurance, software subscriptions, accounting and bookkeeping fees, bank fees on business accounts, and advertising costs are all deductible to the extent they relate to business income.
Home-based business expenses
If you run your business from home, you may be able to claim a portion of occupancy costs, rent or mortgage interest, council rates, home insurance, as well as running costs. This is different from the employee working-from-home method. The calculations are different, and the requirements are stricter. Claiming occupancy expenses can also affect your CGT main residence exemption when you eventually sell the property. Worth reviewing with a bookkeeper before you claim.
Vehicle expenses
The logbook method is generally more valuable for sole traders with significant vehicle use, as it captures depreciation, registration, insurance, fuel, and maintenance, not just kilometres travelled. You need a logbook covering at least 12 consecutive weeks to establish the business-use percentage.
Superannuation contributions
Employees have superannuation paid on their behalf under the Super Guarantee. Sole traders don’t, which is worth understanding before assuming the rules are the same.
If you’re self-employed and making voluntary super contributions from after-tax income, those contributions can be claimed as a tax deduction. The process isn’t automatic. You need to lodge a Notice of Intent to Claim with your super fund before you submit your return, and the fund needs to acknowledge it. Miss that step and the deduction doesn’t apply.
The concessional contributions cap sits at $30,000 for 2024-25, across all concessional contributions, including any employer contributions if you also have employed income. Personal deductible contributions count toward that cap. Going over it triggers additional tax, which tends to come as a surprise. For more on how super obligations work in practice, the Payday Super 2026 guide is worth a read.
For sole traders who are profitable but don’t have a structured super strategy, this is often an underused deduction. It reduces taxable income in the year of contribution and builds the super balance at the same time. Whether it makes sense depends on cash flow and what else is happening in the return. Worth running through with a bookkeeper before the end of the financial year rather than after.
Prepaid expenses
Sole traders operating on a cash basis can sometimes prepay up to 12 months of deductible expenses before 30 June and claim them in the current year. This is a legitimate strategy to bring forward deductions, but it requires planning, not a last-minute scramble.
The self-employed tax position is genuinely more complex than employee tax. The upside is that more is deductible. The requirement is that records are more important, not less.
Record Keeping: What You Actually Need
The ATO’s minimum requirements:
- Keep records for five years from when you lodge the relevant return
- Written evidence (receipts, invoices, bank statements) for most claims above the thresholds covered earlier
- A logbook for vehicle claims using the logbook method
- A diary or records to support working-from-home hours under the fixed rate method
- Records showing the work-use percentage for any dual-use items
Digital records are accepted. A photo of a receipt stored in a folder is fine. An expense tracking app that records and categorises as you go is better, and it also makes the conversation with your bookkeeper significantly faster at year’s end. If you’re unclear on how long to keep business records in Australia, the requirements vary depending on the type of record.
What doesn’t work: approximate estimates with no supporting documentation, a folder of faded thermal receipts that are no longer legible, or a spreadsheet with no source records to back it up.

FAQs
What can I claim on tax without receipts in Australia?
You can claim up to $300 combined for work-related expenses, up to around $150 for laundry costs, and up to 5,000 km under the cents-per-kilometre method, all without formal receipts. For small expenses under $10 where the total is under $200, a diary record is acceptable. Outside these thresholds, the ATO expects written evidence.
Is a tax write-off the same as getting the money back?
No. A tax write-off reduces your taxable income, not your tax bill directly. You save the equivalent of your marginal tax rate on the deducted amount. For most people, that’s somewhere between 19% and 45% of the expense, not 100%. You still spend the money; you just pay less tax as a result.
What’s the difference between a tax deduction and a tax offset?
A deduction reduces your taxable income before your tax is calculated. An offset reduces the tax you owe after it’s been calculated. Offsets are more directly valuable on a dollar-for-dollar basis, but eligibility is restricted. Most working Australians access the Low Income Tax Offset; other offsets apply to pensioners, seniors, and specific situations.
Can sole traders claim more than employees?
Generally yes. Sole traders can claim business operating costs, home-based business expenses, including occupancy costs in some circumstances, and a wider range of vehicle and equipment claims. The record-keeping obligations are also more detailed.
What are the ATO’s main red flags for work-related claims?
The ATO looks for 100% work-use claims on items that are likely used privately, deduction amounts that seem inconsistent with the occupation, and missing or insufficient documentation. Watches, grooming, and commuting costs are frequently overclaimed. WFH double-dipping is also flagged regularly.
What happens if I over-claim a deduction?
The ATO can amend your return, require repayment of the excess refund, and charge interest and penalties. In serious cases of false or misleading claims, penalties can be significant. The risk isn’t worth the savings on a borderline claim.
Can I claim the instant asset write-off in 2025-26?
The temporary $20,000 threshold ended on 30 June 2025. The threshold for 2025-26 reverted to a much lower figure for most small businesses unless further legislation was passed. Confirm the current position with a registered tax agent or check the ATO directly before making purchasing decisions based on this provision.
Can a bookkeeper help me maximise my tax deductions?
A registered BAS agent or bookkeeper can help you maintain records correctly throughout the year, identify deductible expenses you might be missing, and ensure your accounts are in the right shape before you or your tax agent lodges. Good bookkeeping is itself a deductible expense. The cost of managing your tax affairs is claimable under ATO rules.
