What Can You Actually Claim on Tax in Australia (2026 Guide)

The three rules every deduction has to pass

Before any specific category, the ATO applies three general tests to every deduction. The data on denied claims shows that most rejections come from failing one of these three, not from the category being inherently wrong.

1. The expense must be incurred in earning your assessable income. There has to be a clear connection between the cost and the income you earned. A nurse buying nursing scrubs passes. A nurse buying everyday casual clothes for the bus to work doesn’t.
2. You must have spent the money yourself, and not been reimbursed. If your employer reimbursed you for the cost, you can’t claim it. The ATO’s data-matching can detect employer-reported reimbursements.
3. You must have a record to prove it. The general standard is written evidence (receipt, invoice, bank statement, or similar). Records must be kept for five years from the lodgment date.

What stands out about these three rules is how often they’re treated as guidelines instead of hard requirements. They’re not guidelines. The ATO’s deductions you can claim hub sets them out at the start of every category page for a reason.

For broader context on how tax filings fit together, the Australian tax system overview and the tax return lodgment article on this site cover the surrounding framework.

Work-related expenses — the biggest category

Work-related expenses make up the largest share of individual deductions in Australia. The ATO’s work-related expenses page breaks them down into a handful of subcategories. Here’s what each one actually means in practice.

Vehicle and travel expenses

You can’t claim the daily commute between home and a regular workplace. That’s private travel. What you can claim:

• Travel between two separate workplaces on the same day (e.g., a teacher visiting a second school)
• Travel from one workplace to a second job
• Travel for work duties (visiting clients, attending offsite training, picking up work supplies)
• Travel where you’re carrying bulky tools that can’t reasonably be left at work

For vehicle claims, two methods exist: cents-per-kilometre (capped at a defined number of km per year, no logbook needed) and the logbook method (12-week representative logbook plus actual costs). The logbook method usually produces a bigger deduction for high-business-use drivers but requires more records.

Clothing, laundry, and dry-cleaning

Three categories of clothing are deductible: occupation-specific (chef whites, nurse uniforms), protective (steel-cap boots, hi-vis), and compulsory uniforms with a registered design. Conventional clothing — even if your employer requires you to dress smartly — isn’t deductible.

Laundry of deductible clothing is claimable. Up to a defined annual amount, the ATO accepts a reasonable estimate without detailed records. Above that, you need diary records.

Self-education expenses

Self-education is deductible when the course directly relates to your current employment — improving skills you already use, leading to higher income from the same role, or maintaining a professional qualification. It’s not deductible for courses that get you a new job in a different field.

Eligible expenses include course fees (other than HELP-loan amounts), textbooks, stationery, and travel between home and the educational institution in some cases. The full rules are on the ATO’s self-education page.

Tools, equipment, and assets

Work-related tools and equipment used for work are claimable. Items below a defined threshold (currently $300) can be claimed in full in the year purchased. Above that threshold, the cost is depreciated (decline in value) over the asset’s effective life.

Other work-related expenses

The catch-all category that quietly contains some of the most commonly-missed deductions:

• Union fees and professional association memberships
• Work-related books, magazines, and trade journal subscriptions
• Tools, equipment, and computer-related work expenses
• Annual practising certificate fees
• Professional indemnity insurance for self-employed workers
• Income protection insurance (paid outside super)

Working-from-home expenses also fall under work-related. They have their own rules and methods, covered in the dedicated WFH tax deductions article.

The cost of managing tax affairs

This is the deduction more taxpayers should claim and don’t. The ATO’s cost of managing tax affairs page sets out what’s covered.

Claimable in this category:

• Fees paid to a registered tax agent for preparing or lodging your return
• Subscription costs for tax software (e.g., commercial tax preparation tools)
• Travel costs to and from a tax agent’s office
• Costs of objecting to or appealing an ATO decision
• Cost of attending tax-related courses or seminars

The data here is interesting: tax agents’ own fees being deductible essentially means the government partly subsidises professional tax help. For taxpayers paying $200-400 to a tax agent, getting that back as a deduction reduces the net cost meaningfully — and the agent’s expertise often surfaces other deductions the taxpayer would have missed.

Donations to charity

Donations are deductible only if made to organisations registered as Deductible Gift Recipients (DGRs). The ATO’s gifts and donations page covers the specifics.

Key rules:

• The recipient must be a DGR — most well-known charities are, but it’s worth checking the official ATO DGR register
• The donation must be a genuine gift — no personal benefit received in return
• For donations above $2, you need a receipt
• Crowdfunding contributions, fundraising raffle tickets, and “fundraising dinner” payments where you receive food/entertainment are generally not deductible

What stands out is how often workplace giving (regular small donations through payroll) goes unclaimed. It’s a clean deductible expense documented through PAYG records — but many employees forget to mention it at lodgment, and it doesn’t always pre-fill automatically.

Investment-related deductions

If you have investments — shares, bonds, managed funds, or rental property — a meaningful share of investment-related expenses is deductible against the income those investments produce.

For shares and managed investments:

• Investment management or advice fees
• Margin loan interest where the loan is for investment purposes
• Cost of investment-related publications and tools

For rental properties (a significant category for Australian investors):

• Loan interest on the investment loan
• Council rates, water charges, body corporate fees
• Repairs (immediate) versus capital improvements (depreciated)
• Property management fees
• Depreciation of fittings and capital works
• Travel for property inspections (with significant restrictions since 2017)

The data on rental-property deductions shows the ATO scrutinises this category closely — notably, the line between “repairs” (immediately deductible) and “improvements” (depreciated over time) gets re-examined often. A registered tax agent is generally worth the cost for property investors.

Personal super contributions

Personal contributions to super made from after-tax income can be deductible against your taxable income, with several caveats.

To claim:

• The contribution must be made within the financial year and before any caps are exceeded
• You must lodge a “Notice of intent to claim a deduction” with your super fund and receive an acknowledgment
• The fund must include the contribution in its assessable income (so 15% contributions tax applies inside the fund)
• You must be eligible to contribute personally (most working-age people are, but some restrictions apply for very high contributions or early-access scenarios)

The catch most people miss: without the Notice of intent step, the contribution is treated as a non-concessional (after-tax) contribution and isn’t deductible. The notice has to be lodged before the earlier of: the end of the next financial year, or the date you lodge your return for that year.

For the broader rules around super, our superannuation eligibility article and early-access rules article cover the wider context.

What you can’t claim — common mistakes

Just as important as what’s claimable is what isn’t. The most commonly denied claims at audit:

• Daily commute — between home and your regular workplace, not deductible (with narrow exceptions for itinerant workers and those carrying genuinely bulky equipment)
• Conventional clothing — business suits, smart-casual office wear, formal shoes — not deductible even when employer requires “professional attire”
• Gym memberships — generally not deductible, even for jobs requiring fitness, unless very narrow conditions are met (e.g., professional sportspeople)
• Childcare expenses — not a tax deduction (separate Child Care Subsidy applies, covered in our aged care and childcare costs article)
• Self-education for getting a new job in a different field — only current-job-related study is deductible
• Personal living expenses — food, drink, personal grooming, even if consumed at work
• Speeding fines and parking fines — never deductible, even if incurred while on work duties

For workers with multiple jobs specifically, additional complications around tax deductions and withholding apply — the multiple jobs and tax article covers those.

Frequently asked questions

What’s the most commonly missed tax deduction in Australia?

The cost of managing tax affairs is one of the most commonly missed deductions. Tax agent fees, tax-software subscriptions, and travel costs to see a tax agent are all deductible. Many taxpayers also miss income protection insurance premiums (paid outside super) and small work-related subscriptions. Records are required, and the deduction is claimed in the year the expense was incurred.

Do I need receipts to claim tax deductions in Australia?

For most claims, yes. The ATO requires written evidence for any single claim above $300 in total work-related expenses (and even below that for specific categories). Donations need receipts for any claim above $2. Records must be kept for five years from the lodgment date. Some categories (uniforms below set thresholds, small consumables) have simpler record requirements but still need basic substantiation.

Can I claim my commute to work as a tax deduction?

No. Travel between home and your regular place of work is private travel and isn’t deductible, even if you make work calls or carry work tools. Travel between two separate workplaces, travel for work duties (visiting clients, attending offsite training), and travel for itinerant work can be claimable. The ATO’s distinction is whether the travel is part of your job or just getting to it.

The single most-missed deduction in Australia

Looking across the patterns, the single most-missed deduction in Australia isn’t a specific category — it’s the assumption that small expenses don’t matter. Workers leave union fees off because they’re “only $400 a year”. Donations get skipped because the receipts aren’t filed. Income protection premiums are paid through direct debit and forgotten. Subscriptions to professional journals are billed quietly to a credit card and never tallied at lodgment time.

The pattern adds up. Half a dozen $200-400 deductions across categories that genuinely qualify can produce a deduction in the low thousands. At a 32.5% marginal tax rate, that’s $400-700+ of refund that’s left unclaimed each year.

So the practical move, especially heading into tax season, is to set up a simple records routine now — a folder (digital or paper) where receipts, invoices, and confirmation emails go through the year, and a quick reconciliation at lodgment. The ATO’s deductions hub remains the authoritative starting point for any specific category, and the myDeductions tool inside the ATO app makes record-keeping easier than it used to be.

For workers whose situation involves multiple income sources, working from home, or investment property, the deduction picture is bigger and more rewarding to get right. A registered tax agent is generally worth the cost for those situations — and the agent’s fee is itself deductible, which is the kind of system quirk that makes plain-English explainers like this worth writing.
