What records do I need to keep?

You generally need to keep receipts, bank statements, or other written evidence for all expenses you claim. For some expenses like work-related car use, you may need to keep a logbook.

What's the difference between a deduction and a tax offset?

A tax deduction reduces your taxable income, so the benefit you receive depends on your marginal tax rate. A tax offset (or credit) directly reduces the amount of tax you have to pay, dollar for dollar.

How long do I need to keep my tax records?

You must keep your records for five years from the date you lodge your tax return.

Can I claim deductions if I'm not an Australian resident?

Generally, non-residents can only claim deductions related to their Australian-sourced income. The rules can be complex, and it's best to seek professional advice.

What work-related expenses can I claim as a tax deduction in Australia?

You can generally claim deductions for expenses directly related to earning your income. Common claims include: work uniforms and protective clothing (with mandatory laundry), vehicle expenses (using the logbook or cents-per-km methods), home office running costs, self-education expenses, tools and equipment, and union fees. The expense must be directly related to your job — not private or domestic.

Can I claim home office expenses without a dedicated room?

Yes. The ATO allows you to claim home office running expenses even without a dedicated room, using the 'fixed rate' method (67 cents per hour for 2026-27). This covers electricity, gas, internet and phone costs. You must keep a record of your hours worked from home. A separate room is only required for the 'actual cost' method.

How much can I claim for laundry of work clothes?

If you wash your own work uniforms or protective clothing, you can claim $1 per item per load (or 50 cents per item if you mix items in the same load). If your total claim is under $150, you don't need receipts, but you do need to be able to show how you calculated the amount.

What is the limit for claiming work-related expenses without receipts?

You can claim up to $300 in total work-related expenses without receipts. However, you must have actually spent the money and be able to demonstrate how you calculated the amount. Once your claims exceed $300, you need receipts for the full amount, not just the excess.

Do tax deductions reduce how much HECS I repay?

No — this is an important distinction. While deductions reduce your taxable income (and therefore your income tax), your HECS/HELP repayment is calculated on your 'repayment income', which adds back some deductions. Salary sacrifice to super, for example, does not reduce your HECS repayment income.

How Deductions Impact Your Refund

Tax deductions don't reduce your tax bill dollar-for-dollar. Instead, they reduce your taxable income. The actual cash benefit you receive depends on your marginal tax rate (the rate of tax you pay on your highest dollar of income).

For every $100 you claim in deductions, a person on a 30% tax rate gets approximately $30 back.
