Understanding Taxes and the ATO Basics
Before getting into deductions and refunds, let’s break down the key elements of the Australian tax system and the ATO:
- Taxable Income: The total income on which tax is calculated after deductions.
- Tax Withheld (PAYG): Money taken from your pay and sent to the ATO as advance tax payment.
- Tax Return: Annual statement where you report income and deductions to the ATO.
- Tax Refund: Money returned if you paid too much tax during the year.
- Tax Debt: Money you owe the ATO if too little tax was paid.
Real-Life Stories: Aussie Tax Wins
Emma’s Education Expense Discovery
Emma, a Brisbane school teacher, wasn’t confident about claiming expenses until she found that costs for professional development courses, teaching supplies, and home office internet were deductible. She saved over $1,200 on her taxes last year, money she put towards a family holiday.
Jake’s Trade Tools Triumph
Jake, a Perth electrician, used to just throw out his receipts. This year, he organised his expenses, tracked mileage, and claimed tools and safety gear purchases. That careful record-keeping earned him a nearly $2,000 refund and peace of mind.
Lisa’s Rental Property Refund
Lisa, a Sydney landlord, was surprised that council rates, maintenance, and property management fees were deductible. Properly logging these expenses helped her reduce taxable rental income and secure a tidy refund.
Tax Deductions Explained
Tax deductions reduce your taxable income, which means you pay less tax overall. The ATO allows you to claim expenses that relate directly to earning your income and that you haven’t been reimbursed for.
Who Can Claim Tax Deductions?
- Employees (full-time, part-time, casual)
- Contractors and freelancers
- Small business owners
- Investors (rental properties, shares)
- Others earning taxable income

How to Calculate and Claim Vehicle & Travel Expenses
Calculating deductions for car and travel costs is one of the trickier parts but often a big money-saver for tradespeople and those required to drive for work.
Methods to Claim Vehicle Expenses:
- Cents Per Kilometre Method
Claim a set rate per kilometre (currently up to 5,000km/year). Easy to use, no receipts needed, but limit applies. - Logbook Method
Keep a detailed logbook of all business journeys for 12 weeks, then apply that business-use percentage to all car expenses (fuel, insurance, maintenance).
Step-By-Step Guide: How to Claim Tax Deductions
Step 1: Organise Your Records
Keep receipts, invoices, bank/credit card statements, and logbooks stored safely—electronic copies are accepted if legible.

Sort your claims into categories matched to ATO definitions; this helps streamline lodging your return.
Step 3: Use ATO Tools and Resources
- The ATO myDeductions app helps track expenses digitally throughout the year.
- The ATO website offers guides, calculators, and record-keeping templates.
Step 4: Choose Lodging Method
- DIY myTax: Simple salaried workers with straightforward claims can lodge online.

Step 5: Lodge Your Return by Deadline
Generally due by 31 October. Extensions may apply when using a tax agent.

How Tax Refunds Work
If the tax you paid throughout the year (usually withheld by employer) is more than your final tax bill, you’ll receive a refund. Tax refunds are not “free money” but a return of your own overpaid tax.
How to Maximise Your Refund:
- Claim all eligible deductions accurately.
- Check for tax offsets (low income, seniors, seniors and pensioners tax offset).
- Submit returns early to get money sooner.
- Use a tax professional to identify less obvious claims.
