Tax Deductions Australia — What You Can Claim on Your Tax Return

A tax deduction reduces your taxable income, which reduces the tax you pay. To claim a deduction under ATO rules, the expense must be directly related to earning your income, you must have incurred it yourself (not been reimbursed), and you must have a record to prove it. Understanding what you can and can’t claim is one of the most practical ways to reduce your annual tax bill.

This cluster covers every major category of work-related and investment deductions available to Australian individuals — from the most common (working from home, vehicles) to occupation-specific deductions for nurses, teachers, tradies, and other professions.

The 3 Tests for a Tax Deduction

Every deduction claim in Australia must pass three basic tests under the Income Tax Assessment Act 1997:

1. Incurred in gaining or producing assessable income: The expense must directly connect to earning your income. Personal expenses are not deductible.

2. Not capital, private, or domestic in nature: General lifestyle costs (food, clothing, commuting, gym membership) are not deductible — even if you work from home or your job is physically demanding.

3. Not exempt by specific provision: Some expenses that would otherwise qualify are explicitly excluded (e.g., most fines and penalties are not deductible).

The ATO’s “golden rule”: if the expense would be incurred even without your job, it is probably not deductible. If you would not have incurred the expense but for your employment or investment activity, it is likely deductible.

The $300 Substantiation Threshold

You can claim work-related expenses up to $300 in total without receipts — but only if you genuinely incurred the expenses. Once you claim more than $300 in work-related deductions, all work-related claims must be substantiated with receipts or other evidence. The $300 threshold is not an automatic entitlement.

The ATO uses sophisticated data-matching and benchmarking. Claims that are significantly above the average for your occupation and income level attract scrutiny. The ATO publishes occupation-specific guides showing the average deduction claimed — and automatically flags outliers.

Work-Related Deductions — The Most Commonly Claimed

Investment Property Deductions — Summary

Investment property deductions are a major category:

Immediately deductible: Interest on investment loan, council rates, insurance premiums, property management fees, repairs and maintenance (existing damage — not improvements), advertising for tenants, stationery and postage, subscriptions to property investment resources.

Depreciable over time (not immediately deductible): Capital improvements (renovations, extensions), plant and equipment (appliances, carpets, blinds installed after 9 May 2017 for second-hand properties). New properties have more generous depreciation access.

Not deductible at all: Purchase price and stamp duty (these form the cost base for CGT purposes), expenses for periods the property is genuinely not available to rent, personal travel to inspect property in some circumstances.

Frequently Asked Questions

Can I claim a tax deduction for working from home?

Yes — the ATO provides two methods for home office deductions. The revised fixed rate method (67 cents/hour from 2022–23) covers electricity, internet, phone, and stationery. The actual cost method requires precise records and proportionate calculation. Under either method, occupancy costs (rent, mortgage interest) are generally not deductible unless your home is your place of business.

Can I deduct my car when I drive to work?

No — travel from home to your regular place of work is considered a private expense and is not deductible. Car deductions are available for travel between work sites, visiting clients, carrying heavy tools required for work, and other work-related purposes. The “cents per kilometre” method (88 cents/km in FY2024–25) or the logbook method are the two approved approaches.

What deductions can I claim without receipts?

The ATO allows claims up to $300 total in work-related deductions without receipts — provided you genuinely incurred the expense. For laundry of uniforms, up to $150 can be claimed without detailed records. For car travel using the cents per kilometre method, a written note of the trip (date, km, reason) is sufficient. Beyond these specific allowances, receipts or bank records are generally required.
