Understanding Your Tax Return — A Beginner's Guide

A plain-English walkthrough of every section of your individual tax return so you know exactly what's happening.

What Is a Tax Return?

A tax return is a form you lodge with the Australian Taxation Office (ATO) each year. It tells the ATO how much income you earned and what deductions you're claiming. Based on this, the ATO calculates whether you owe more tax or are entitled to a refund.

Key Sections of Your Tax Return

1. Personal Details

Your name, address, date of birth, Tax File Number (TFN), and bank account details for any refund.

2. Income

This includes salary and wages (from your payment summary or income statement), interest from bank accounts, dividends from shares, government payments (e.g., JobSeeker, pensions), rental income, and any other income like freelancing or side jobs.

3. Deductions

Expenses you incurred to earn your income. Common deductions include work-related car expenses, travel, clothing and laundry, self-education, home office costs, tools and equipment, and union fees.

4. Tax Offsets

Offsets (also called rebates) directly reduce the amount of tax you owe. Common ones include the low-income tax offset, the seniors and pensioners tax offset, and the private health insurance rebate.

5. Medicare Levy

Most taxpayers pay a 2% Medicare levy on their taxable income. If you don't have private hospital cover and earn above a certain threshold, you may also pay the Medicare levy surcharge (1%–1.5%).

When Is It Due?

If you lodge your own return, the deadline is 31 October each year. If you use a registered tax agent like Optium Accountants, you may be eligible for an extended deadline — often as late as May the following year. However, you must be registered with your agent before the 31 October deadline.

How Refunds Work

Throughout the year, your employer withholds tax from your pay (PAYG withholding). When you lodge your return, the ATO compares the tax already paid against what you actually owe. If you've paid too much, you get a refund. If you haven't paid enough, you'll receive a tax bill.
