About Tax Returns 

If you have earned income from 1st July to 30th June, you have to lodge an individual tax return to declare it to the ATO. With this information in hand, the ATO decides whether you have to pay more tax or are owed a refund. 

To avoid any tax disagreement, you should report your investment income, like dividends, interests, and capital gains. According to ATO, there are 4.0 million tax return lodgements as of 31 July 2025, which is 3% less than the same time last year. Not lodging a tax return can result in penalties and increased tax liability.

Documents Required To Lodge a Tax Return

Before heading towards how to file a tax return, let’s take a quick look at gathering some important documents. ATO needs these documents and information from you to figure out your income, calculate deductions, and determine whether you are owed a refund or need to pay additional tax. Here are the required documents to start the lodgment process:

• Your details, like Tax File Number (TFN), bank account, and contact information.
• Income record, which involves STP lodgements, payment summaries or income statements, bank interest, dividends, and rental income.
• Dedication records like work-related, travel, home, office, and education expenses.
• Your private health insurance statement.
• Receipts for charity donation (in case of donation).
• Any other relevant documents, like managed fund statements and capital gains records.

Who Should Lodge an Individual Tax Return?

If you are a resident, you have to lodge a tax return if your earned income is above the tax-free threshold and you have multiple income sources, like employment, investments, and rental property. If you are a non-resident and earning Australian income, you still have to file a tax return.

Here is another thing to mention: if your income is under the tax-free threshold ($18,200) and you don’t have to lodge tax, you have to submit a Non-Lodgment Advice to the ATO. It acts as a notification to ATO that saves you from tax-related reminders or penalties.

3 Ways To Lodge an Individual Tax Return 

Let’s come to the point: how to file taxes individually. Here are 3 ways to do so, described in detail. The deadline to lodge a tax return for the first 2 ways is before 31 October.

1. Free Online Lodgement Service

ATO facilitates Australians to file tax returns with ease through its free online lodgement service. Now you can easily prepare and lodge your own tax return file online. You can say this is the quickest, safest, and secure way to lodge your tax return, which is processed in just 2 weeks.

You can get access to this service by creating a myGov account and then linking it to the ATO. Without downloading any software, you can access myTax, which enables you to file taxes on your mobile, tablet, or computer. This way of filing taxes allows you to:

• Get pre-filled information by late July from your employers, banks, government agencies, health funds, and third parties.
• Securely run and protect your tax return information.
• Lodge anytime, anywhere you want.
• Get a lodgment receipt via email to verify your lodgment.

2. Paper Return Tax 

This way of tax return lodgment allows you to file a tax return by filling in a paper form and sending it to the ATO by post. For this, you need:

• Individual tax return instructions.
• A printed copy of the Tax Return for Individuals form.

After that, you have to follow the instructions to complete your tax return. There is also a supplementary section for those who have business, capital gains, foreign, or rental income to lodge a tax return for individuals. Once you’re done filling in the required sections, you can post it to ATO. This process handles most refund issues within 50 business days.

3. Lodge With a Registered Tax Agent

If you don’t want to face the complexities of the lodging tax return process, you can get help from registered tax agents like those available at Outback Accounting. With a professional tax agent, you can lodge a tax return with fair service charges and comply with the ATO regulations effectively.

There are online and physical tax services available, yet they must be registered with the Tax Practitioners Board (TPB). Another major advantage of having a tax agent for filing tax returns is that the ATO allows them to lodge returns for their clients after the usual 31 October deadline. This due date also depends on your situation and when you engage with a tax agent.

When Can You Lodge Your Tax Return in Australia?

Lodgement for the previous financial year opens on 1 July each year. So for the 2025–26 income year, you can start lodging from 1 July 2026.

However, the ATO recommends waiting until late July before lodging online. That’s when pre-fill data — including your STP income from employers, bank interest, dividends, and private health information — becomes available in myGov. Lodging too early increases the chance of missing income or receiving an amended assessment later.

Key dates to remember:

• 1 July — lodgement opens for the previous financial year
• Late July — pre-fill data available from most third parties
• 31 October — deadline for individuals lodging their own return
• May the following year — extended deadline available when lodging through a registered tax agent (dates vary based on your history)

If you miss the 31 October deadline without engaging a tax agent beforehand, the ATO may issue a Failure to Lodge (FTL) penalty starting at $330 for small entities, and interest may accrue on any tax you owe.

How To Lodge Your Tax Return Online (myGov + myTax)

Lodging online through myGov is the most popular way for Australians to file their tax return. The process is secure, fast, and most returns are processed within two weeks.

Here’s the step-by-step process:

1. Create a myGov account at my.gov.au if you don’t already have one
2. Link your ATO account to myGov using your Tax File Number and identity verification
3. Open myTax from the ATO section of your myGov dashboard
4. Review pre-fill data — including your income, bank interest, dividends, and private health cover
5. Add any missing income — side hustles, rental property income, capital gains, or foreign income
6. Claim your deductions — work-related expenses, home office, donations, professional fees
7. Review and submit — check your estimated refund or amount owing, then lodge

Common myTax errors sellers encounter:

• Pre-fill data not appearing (usually resolved by waiting until late July)
• STP income not matching payment summary (contact your employer)
• Bank interest missing from smaller accounts
• Health fund details incorrect (update through your fund first)

Once lodged, the ATO typically processes online returns within 14 days. You’ll receive a Notice of Assessment via your myGov inbox once processing is complete.

Paper Tax Return: How To Lodge By Post

While most Australians now lodge online, the paper return is still available for those who prefer it or need to lodge for a past year that’s no longer supported in myTax.

To lodge a paper tax return:

1. Download the Tax Return for Individuals form from the ATO website (or order a printed copy from the ATO)
2. Download the Individual Tax Return Instructions for the relevant financial year
3. Complete the form using your income statements, receipts, and records
4. Use the Supplementary Section if you have business, capital gains, rental, or foreign income
5. Post the completed form to:

Australian Taxation Office GPO Box 9845 [Your capital city, e.g. Sydney NSW 2001]

The ATO processes paper returns in around 50 business days significantly slower than online lodgement. Paper is worth considering if you don’t have reliable internet access, need to lodge for a prior year that’s no longer supported in myTax, or genuinely prefer physical documentation. For most sellers, online is faster, easier, and less prone to error.

Lodging Your Tax Return With a Sydney Tax Agent

Using a registered tax agent is the third — and for many Australians, the smartest — way to lodge a tax return. A tax agent handles everything from gathering documents to lodging with the ATO, and they can often identify deductions you’d miss on your own.

The main benefits of using a tax agent:

• Extended deadlines — clients of registered tax agents typically have until 15 May the following year to lodge, rather than 31 October
• Maximum legal deductions — a tax agent knows what you can legitimately claim in your industry or circumstances
• ATO liaison — if the ATO has queries about your return, your tax agent handles it
• Peace of mind — professional lodgement reduces the risk of errors, audits, and penalties
• Deductible fees — tax agent fees are themselves tax-deductible in the following year’s return

Cost expectations for lodging with a Sydney tax agent:

• Simple individual return (PAYG income only): $150 – $250
• Individual return with investment property or share portfolio: $300 – $500
• Sole trader or small business return: $500 – $1,200+

Before engaging any tax agent, check they are registered with the Tax Practitioners Board (TPB) at tpb.gov.au. Anyone charging for tax advice or lodgement without TPB registration is operating illegally.

Individual vs Personal vs Australian Tax Return — What’s the Difference?

If you’ve searched for tax return information, you’ve probably seen terms like “individual tax return,” “personal tax return,” and “Australian tax return” used interchangeably. These all refer to the same thing.

An individual tax return — also called a personal tax return is the return lodged by an Australian resident individual to declare their income and calculate their tax liability for a financial year. This is what most Australians lodge each year through myGov, a paper form, or a tax agent.

This is different from:

• Company tax return lodged by Australian companies (Pty Ltd) using a different form and process
• Trust tax return — lodged by trustees of family trusts, unit trusts, and other trust structures
• Partnership tax return lodged by partnerships operating a business
• SMSF tax return lodged by self-managed superannuation funds

If you earn income personally (from a job, freelance work, investments, rental property, or a sole trader business), you lodge an individual tax return. If you operate through a company, trust, or partnership, that entity lodges its own tax return separately from your personal one.

Common Tax Return Lodgement Mistakes To Avoid

Even with pre-fill data and online lodgement, Australians still make the same mistakes on tax returns every year. Most of these can be avoided with a bit of care.

Missing income from side hustles. If you’re earning from Uber, Airtasker, freelance work, or selling on eBay, that income needs to be declared — even if you’re not registered as a business. The ATO now receives data directly from many platforms and cross-checks it against tax returns.

Forgetting capital gains. Sold shares, cryptocurrency, or an investment property during the year? Capital gains (or losses) must be included in your return, calculated correctly, and any CGT discount applied properly.

Missing deductions you’re entitled to claim. Work-from-home expenses, professional memberships, subscriptions, tools of trade, self-education, and industry-specific deductions are commonly under-claimed. The ATO publishes occupation-specific deduction guides worth reviewing before lodging.

Bank interest and dividend errors. Interest from smaller savings accounts or dividends from single-share holdings often don’t appear in pre-fill data. Check every account.

Claiming personal expenses as business. Deductions must have a genuine business or income-earning purpose. Personal spending mixed into business claims is one of the fastest ways to trigger an ATO review.

Not keeping records. The ATO requires you to keep supporting evidence for deductions for five years. Lost receipts often mean lost deductions.

Frequently Asked Questions (FAQs)

1. When can I lodge my tax return in Australia?

Lodgement opens on 1 July each year for the previous financial year (July to June). However, the ATO recommends waiting until late July before lodging, when pre-fill data from employers, banks, and health funds becomes available. Lodging too early increases the chance of missing income or receiving an amended assessment later.

2. Can I lodge my own tax return without an accountant?

Yes. Most Australians can lodge their own tax return online using myTax through their myGov account. It’s free, secure, and most returns are processed within two weeks. However, if you have investment properties, share portfolios, business income, or complex deductions, a registered tax agent can often save you money and time by identifying deductions you’d miss.

3. Where do I send my paper tax return in Australia?

Paper tax returns are posted to the ATO’s dedicated PO Box for your capital city. For Sydney residents, the address is Australian Taxation Office, GPO Box 9845, Sydney NSW 2001. Make sure your return is complete, signed, and includes all supporting schedules before posting. Paper returns take approximately 50 business days to process.

4. How long does it take for the ATO to process my tax return?

Online tax returns lodged through myTax are typically processed within 14 days. Returns lodged by a registered tax agent take a similar timeframe. Paper returns take significantly longer — around 50 business days. Once processed, the ATO issues a Notice of Assessment showing your refund amount or any tax payable.

5. What documents do I need to lodge my tax return?

You’ll need your Tax File Number (TFN), bank account details for any refund, income statements from your employer, records of investment income (interest, dividends, rental income), receipts for any deductions you’re claiming, your private health insurance statement, and records of any capital gains or losses. Keep records for five years in case of an ATO review.

6. What’s the deadline for lodging a tax return in Australia?

If you’re lodging your own tax return, the deadline is 31 October. If you’re using a registered tax agent, the deadline is generally extended to 15 May the following year, provided you engaged the agent before 31 October. Missing the deadline can result in a Failure to Lodge penalty starting at $330 for small entities.

7. How do I apply for a tax return refund?

You don’t apply separately for a refund — your refund is calculated automatically based on the information in your tax return. If your employer has withheld more tax than you owe, or if you’re claiming eligible deductions, the ATO will refund the difference to the bank account nominated in your return. Most refunds arrive within 14 days of online lodgement.

8. Can I lodge my Australian tax return from overseas?

Yes. You can lodge your Australian tax return from anywhere in the world using myGov and myTax, provided you have your login details and access to an Australian bank account for any refund. You can also engage an Australian registered tax agent to lodge on your behalf — many operate remotely and can handle everything via email and video calls.

9. What happens if I make a mistake on my tax return?

If you spot a mistake after lodging, you can amend your return online through myGov, submit a written amendment, or ask a registered tax agent to amend it for you. Individuals generally have two years from the date of the original Notice of Assessment to amend. Amending as soon as you notice the error reduces the risk of penalties.

10. How much does it cost to lodge a tax return with a tax agent in Sydney?

Costs vary depending on complexity. A simple individual return with PAYG income only typically costs $150 to $250. Returns with investment properties or share portfolios range from $300 to $500. Sole trader or small business returns start from $500 and can go higher depending on scope. Tax agent fees are themselves tax-deductible in the following year’s return.
