How to Lodge Your Tax Return Online in Australia

Tax season in Australia runs from 1 July to 31 October each year. If you're looking to lodge your tax return online, you've got several options. Whether you're an employee, sole trader, or rental property investor, this guide walks you through everything you need to know about lodging your 2025-26 tax return online.

Who Needs to Lodge a Tax Return in Australia?

If you earned income during the 2025-26 financial year (1 July 2025 to 30 June 2026), you generally need to lodge a tax return with the Australian Taxation Office (ATO). This includes income from employment, your own business, investments, rental properties, government payments, and foreign sources.

Even if you earned below the tax-free threshold of $18,200, you may still need to lodge if you had tax withheld from payments or received certain government benefits.

Option 1: Lodge Through myTax (ATO Online)

The ATO's free online tool, myTax, is available through your myGov account. It's straightforward for simple returns — think standard employment income with basic deductions. myTax pre-fills much of your information from employers, banks, health funds, and government agencies.

However, myTax has limitations. It doesn't provide personalised tax advice, can't help you identify deductions you might be missing, and offers no support if you have complex circumstances like rental properties, capital gains, or business income.

Option 2: Lodge Through a Registered Tax Agent

This is where a CPA accountant like TechEdge Accounting comes in. When you lodge through a registered tax agent, you get several advantages that myTax simply can't offer.

Professional expertise means your return is prepared by someone who understands the tax code inside and out. A qualified accountant identifies deductions you might not know about, ensures your return is ATO-compliant, and can save you significantly more than the cost of their fee.

Extended deadlines are another major benefit. If you're registered with a tax agent before 31 October, you typically get until 15 May the following year to lodge. This gives you extra time without penalties.

Audit protection means that if the ATO queries your return, your tax agent handles the communication and provides professional representation.

Common Deductions Australians Miss

Working from home expenses have become increasingly significant. If you work from home, you can claim a portion of your electricity, internet, phone, and home office furniture costs. The ATO's fixed rate method allows 67 cents per hour for the 2025-26 year.

Car and travel expenses for work-related travel (not commuting to your regular workplace) can add up quickly. Keep a logbook for 12 consecutive weeks to establish your work-use percentage, then apply it for the full year.

Self-education expenses are deductible when the course directly relates to your current employment and maintains or improves the skills you need for your job.

Professional subscriptions and memberships including union fees, professional body memberships, and industry publications are all deductible.
