Estimate your refund easily using an online tax calculator before you lodge.

What Is a Tax Return and Why It Matters?

A tax return is your official report to the ATO. It shows how much income you earned, how much tax you've already paid, and what deductions you're claiming. The ATO uses this information to work out if you’ve paid the right amount and whether you’re due a refund or owe a bit more.

More importantly, lodging a tax return gives you the chance to claim back work-related expenses like tools, travel, or home office costs. When done correctly, it’s more than just a formality. It could put real money back in your pocket.

When Can You Lodge Your Tax Return in Australia?

The ATO opens up tax season on 1 July every year. While you can lodge your return right away, it’s usually best to wait until late July, when your income and other details are pre-filled in your ATO login. This helps avoid errors or delays.

Who Needs to Lodge a Tax Return?

While not everyone needs to lodge a tax return in Australia, many people do, even if they only worked casually or part-time. If you earned income or had tax withheld during the financial year, there's a good chance you need to lodge. Here's who can lodge tax:

• Anyone who earned over the tax-free threshold

• Those with multiple income streams (jobs + gig economy)

• If tax was withheld from any payments

• If you received government benefits or investments

Essential Documents You’ll Need Before You Lodge

Before you sit down to lodge your tax return, it’s important to have all your documents ready. Being organised not only saves time but also ensures you don’t miss any income or deductions. Having the right records on hand can help you lodge accurately, claim everything you're entitled to, and avoid delays or audits from the ATO.

Before you lodge your tax return, gather the right documents.

Being prepared makes things much easier. Here’s what to collect:

1. Tax File Number (TFN)

2. PAYG summaries or income statements

3. Bank and investment income details

4. Private health insurance statement

5. Receipts for work-related deductions

6. ATO and myGov login details

   
   

A little preparation goes a long way in getting your maximum refund.

Choosing How to Lodge Your Tax Return

Choosing how to lodge, whether online, with a tax agent, or by paper, depends on how complex your tax situation is and how much support you need. You've got two main options:

• Online using MyTax:

  If your tax affairs are straightforward (such as having a single job and no major deductions), you can lodge your return yourself using the ATO’s MyTax system. It's a free, government-provided online tool available through your MyGov account.

  
  

• Using a Tax Agent:

  
  

  Tax agents are experts in maximizing your deductions and staying on the right side of the ATO. They access your information via the secure tax agent portal, which allows them to simplify the process and often extend your due date beyond the standard October deadline.

  
  

How Long Does a Tax Return Take?

Once lodged, the ATO typically processes electronic tax returns within 2 weeks. However, paper returns can take up to 10 weeks. If you need your cash fast, lodge early and electronically.

For quicker results, double-check your pre-filled data and ensure everything matches.

Maximizing Your Tax Refund

Lodging your tax return isn’t just about compliance, it’s your chance to get money back in your pocket. But to do that, you need to know what deductions you're eligible for and make sure nothing gets missed. Many Australians miss out on hundreds of dollars simply because they don’t realise what they can claim.

• Internet and phone usage for work

• Union fees or professional memberships

• Laundry for uniforms

• Tools or tech used for your job

Common Mistakes to Avoid When Lodging a Tax Return

Even with the best intentions, it’s easy to make small mistakes when lodging your tax return, and those mistakes can lead to delays, missed deductions, or even ATO audits. Here are some of the most common slip-ups to watch out for:

• Not waiting for pre-filled data

  Lodging too early can mean missing income that hasn’t been reported yet. The ATO usually completes pre-filling by late July, so waiting a couple of weeks can help you avoid errors.

• Forgetting to include side hustle or gig economy income

  Income from platforms like Uber, Airtasker, or Etsy counts, and the ATO is tracking it more closely than ever. Be sure to include all your sources of income, not just your main job.

• Claiming ineligible expenses

  You can only claim deductions that are directly related to earning your income, not personal costs. Claiming things like everyday clothes or non-work-related subscriptions can get your return flagged.

• Not keeping receipts

  The ATO requires proof for most deductions over $300. Even if you lodge now, you must keep receipts for five years in case you're audited later.

• Overlooking bank interest or dividends

  Even a few dollars of interest from your savings account or dividends from shares need to be declared. These amounts are often pre-filled, but always double-check.

  
  

Understanding the Tax Return Deadline

 Don’t miss the tax return deadline.

Don’t let the 31st October deadline catch you off guard. Late lodgement can result in penalties depending on how late you are.

If you're feeling under pressure, don’t stress. Reach out to a tax agent before the deadline, and you may automatically qualify for a deferred due date with no penalty and no drama. Learn more in our article on tax return deadline extensions.

Lodging your Australian tax return doesn’t have to be a headache. With the right preparation, some smart tools, and maybe a little help from a seasoned tax agent, you can take control of your finances and maximize your refund.
