Lodging an annual tax return is a core financial responsibility for most Australians. The process involves correctly reporting all assessable income and claiming eligible deductions for the relevant financial year. A structured approach can simplify compliance and ensure an accurate outcome.
This guide provides a step-by-step overview of how to lodge your tax return for the FY 2025–26 financial year. Understanding your obligations early is fundamental to a smooth and accurate submission to the Australian Taxation Office (ATO).
Based on our work at Baron Tax & Accounting, a common observation is that Brisbane residents who maintain organised digital records throughout the year face significantly fewer challenges at tax time. This simple discipline not only streamlines the process but also helps in identifying all legitimate deductions.
Key Lodgement Pathways
The primary decision is how to prepare and lodge the return. The two main options are lodging it yourself through the government's online portal or engaging a professional. Whether you are a salaried employee or a sole trader operating in Brisbane, the fundamental principles of reporting income and claiming deductions remain the same.
The two primary lodgement methods are:
Self-lodgement via myTax: This is the ATO's digital platform, accessible through a myGov account. It is suitable for individuals with straightforward tax affairs. The system pre-fills some data from employers and banks, but the legal responsibility to verify and complete the information rests with the taxpayer.
Using a Registered Tax Agent: For more complex situations, such as managing investment properties, capital gains, or business income, a tax agent is recommended. They provide expertise, can help identify less common deductions, and often have access to later lodgement deadlines.
Regardless of the chosen method, diligent record-keeping is the most critical element. For foundational guidance on the end-to-end process, refer to this detailed article on how to file taxes.
Step 1: Gather Your Essential Tax Information
A methodical approach to gathering documents is the foundation of an accurate tax return. This preparation ensures all income is reported correctly and all eligible deductions are claimed. It involves collating all income details and substantiating every expense you intend to claim.
While the ATO's pre-filling service in myTax is increasingly comprehensive, the taxpayer remains ultimately responsible for the accuracy of their return.
Documenting Your Income
First, you must compile a complete record of all income received during the financial year. This extends beyond a primary salary and includes various other sources.
Key income sources to document include:
Employment Income: Your income statement (formerly payment summary) is provided by your employer to the ATO and should appear in myTax.
Bank Interest: All interest earned on savings and transaction accounts must be declared. Most Australian banks report this information for pre-filling.
Government Payments: Details of any payments from Services Australia (Centrelink) or the Department of Veterans' Affairs are required.
Dividends: Dividend statements from share ownership are necessary to report payments and any attached franking credits.
Rental Property Income: For property investors, this includes all rent received and any other income, such as retained bonds.
For sole traders and freelancers, this responsibility is greater. You must collate all invoices and records of payments received. Learning how to effectively track business expenses and income is essential for tax compliance.
Compiling Your Deductible Expenses
Next, gather the records for every work-related or tax-deductible expense. A deduction reduces your taxable income, which may result in a lower tax liability or a larger refund. The guiding principle is: no record, no claim.
To claim a deduction, the following three conditions must be met:
You must have spent the money yourself and were not reimbursed.
The expense must be directly related to earning your income.
You must have a record to prove the expense.
Essential Personal Information and Account Access
Administrative errors can cause significant delays. Before starting, ensure you have your Tax File Number (TFN) and that your myGov account is active and linked to the ATO.
Verify that your name, address, and the bank account details for any potential refund are current within your myGov profile. This simple check can prevent a refund from being delayed or sent to an incorrect account. A comprehensive overview of the 8 essential records you need to keep to be ATO-compliant offers deeper insight into documentation requirements.
Step 2: Lodge Your Return
Once all information is gathered, you can proceed with one of the main lodgement methods. Each has its own process and considerations.
Method A: Lodging Your Own Return With myTax
For many individuals, the ATO's myTax platform is the designated tool for self-lodgement. It is accessed via myGov and is designed to be user-friendly, though it requires careful attention to detail. The lodgement period for self-lodgers typically runs from 1 July to 31 October.
Getting Started
Access: Sign in to your myGov account and navigate to the ATO's linked services to launch myTax.
Verify Details: The system will prompt you to confirm personal information, including contact details and the bank account for your refund. It is critical to ensure these details are accurate to avoid processing delays.
Personalise Return: On the 'Personalise return' screen, you select the types of income you received and deductions you plan to claim. This customises the return to show only relevant sections.
Using Pre-filled Data
A key feature of myTax is its ability to pre-fill information reported to the ATO by employers, banks, health funds, and government agencies. While this is a convenient starting point, it is the taxpayer's legal responsibility to verify its accuracy and completeness against their own records.
Manual Data Entry
Any information not pre-filled must be entered manually. This is common for sole trader income, earnings from the gig economy, or foreign-sourced income. For example, a freelance consultant in Brisbane must manually declare all business income based on their own financial records.
The deductions section is where organised records are vital. Every claim must be substantiated. Common claims include:
Work-Related Car Expenses (cents per kilometre or logbook method).
Work-From-Home Expenses (fixed rate or actual cost method).
Self-Education Expenses directly related to your current role.
Donations to registered deductible gift recipients (DGRs).
A detailed tax return checklist can help ensure no eligible claims are missed.
Review and Lodge
After entering all information, myTax provides a real-time estimate of your tax outcome. Review this summary carefully. If the result is unexpected, double-check your entries. Once confident in the accuracy, submit the return. A lodgement receipt will be generated, which should be saved for your records.
Method B: Partnering With a Registered Tax Agent
When financial affairs become more complex, engaging a registered tax agent is a prudent strategy. This is advisable for individuals with investment properties, capital gains from assets like shares or cryptocurrency, or those running a business. (Online tax return with Baron Tax & Accounting)
The primary benefits include:
Extended Lodgement Deadline: Clients of a tax agent typically have a lodgement deadline of May in the following year, providing additional time to organise records.
Specialised Knowledge: Agents apply expert knowledge to complex areas like rental property depreciation, Capital Gains Tax (CGT) calculations, and business income reporting.
Compliance Assurance: They help ensure all claims are legitimate and substantiated, reducing the risk of an ATO audit.
Official ATO data shows a significant reliance on professionals, with tax agents lodging over 7.1 million returns for one recent income year, as per tax time lodgement statistics from the ATO.
It is a legal requirement to use only a registered tax agent. You can verify an agent's credentials on the public register on the Tax Practitioners Board (TPB) website. This ensures they meet the necessary standards for education, experience, and professional conduct.
Step 3: Understand the Calculation
Australia’s progressive tax system means that different portions of your income are taxed at different rates. Understanding these brackets is key to interpreting your assessment.
The tax rates for the 2025–26 income year are outlined below. These rates do not include the 2% Medicare levy, which applies to most taxpayers.
Tax Brackets vs. Offsets
It is important to distinguish between tax deductions and tax offsets.
A deduction reduces your taxable income before tax is calculated.
An offset is a dollar-for-dollar reduction of your final tax liability.

|---|---|
$0 – $18,200 | Nil |
$18,201 – $45,000 | 16c for each $1 over $18,200 |
$45,001 – $135,000 | $4,288 plus 30c for each $1 over $45,000 |
$135,001 – $190,000 | $31,288 plus 37c for each $1 over $135,000 |
Over $190,000 | $51,638 plus 45c for each $1 over $190,000 |
These brackets are applied incrementally. For more detail on how rates and offsets interact, you can review this guide to Australian tax rates.
Step 4: What to Expect After You Lodge
After submitting your return, the ATO will process it and issue a Notice of Assessment (NOA). The NOA is the official summary of your tax outcome for the year. For online lodgements, the standard processing time is approximately two weeks, though complex returns may take longer.
Understanding Your Notice of Assessment
The NOA will detail one of three outcomes:
A tax refund: You have overpaid tax during the year.
A tax payable: You have an amount to pay by a specified due date.
A nil balance: Your tax paid matches your tax liability.
It is crucial to compare the NOA against the return you lodged. If the ATO has made any adjustments, they will be reflected here. If you disagree with an adjustment, you have the right to request a review or lodge an amendment.
Managing a Tax Bill
If your NOA shows a tax payable amount, it will specify a payment due date. For self-lodgers who submit on time, this is typically 21 November. Payment can be made via BPAY or credit/debit card through your myGov account. The ATO offers payment plans for those who may have difficulty paying the full amount by the due date.
Correcting a Mistake
If you discover an error after lodging, you can submit an amendment. This can be done online via myTax or by your tax agent. There is generally a two-year time limit from the date of your NOA to lodge an amendment.

Frequently Asked Questions
What Is the Deadline to Lodge My 2026 Tax Return?
The deadline depends on your lodgement method. If you lodge your own return via the myTax portal, the deadline is 31 October 2026. If you use a registered tax agent and are on their client list before this date, your deadline is typically extended to 15 May 2027. This extension is beneficial for many, including business owners in Brisbane who require more time to finalise their accounts.
How Long Should I Keep My Tax Records?
The ATO requires you to keep all tax-related records for five years from the date you lodge your return. This includes receipts for deductions, income statements, bank and dividend statements, and logbooks. For example, if you lodge your 2026 return on 15 October 2026, you must keep the records until 15 October 2031. Digital storage is a practical way to maintain these records.
What Happens If I Make a Mistake on My Tax Return?
If you identify an error after lodging, you can correct it by lodging an amendment. You generally have two years from the date your Notice of Assessment was issued to do so. This can be done online through myTax or through your tax agent. The ATO will then issue an amended Notice of Assessment reflecting the new outcome.
Do I Need to Lodge If My Income Is Below the Tax-Free Threshold?
Even if you earned less than the $18,200 tax-free threshold, you may still need to lodge a tax return. You must lodge if your employer withheld any tax (PAYG withholding) during the year. If you have determined you do not need to lodge, you should submit a non-lodgement advice to the ATO via your myGov account to prevent your return from being flagged as overdue.
