Whether you're lodging for the first time or you've done it for years, this post will give you the knowledge you need to lodge with confidence.

From gathering the necessary documents to understanding deductions and tax offsets, we've got you covered.

So, let's dive in and explore the ins and outs of lodging your tax return.

Gather Your Documents

The first step in lodging your tax return is to gather all the necessary documents. This includes:

1. Income Statements: Your income statement from each employer (available in ATO online services through myGov; it replaced the old payment summary). Wait until it's marked Tax ready: employers have until 14 July to finalise it. Also gather interest statements from banks, dividend statements and any other records of income.
2. Deduction Receipts: Receipts and records for anything you plan to claim, such as work-related expenses, gifts to deductible gift recipients and the cost of managing your tax affairs.
3. Government Payment Statements: If you received Centrelink payments such as JobSeeker, have the relevant statements (these are also pre-filled in myTax).
4. Private Health Insurance Statement: Your fund's details are usually pre-filled, but have your policy details handy, along with your spouse's details if you had one during the year.
5. Investment Statements: Collect any statements related to your investments, such as shares, rental properties, or managed funds.
6. Personal Information: Have your personal details on hand, including your tax file number, date of birth, contact information and the bank account you want your refund paid into.

Organising these documents ahead of time will make the lodgement process much smoother and ensure you don't miss any important information.

Confirm Your Residency Status

Australia doesn't use filing statuses like the US. Everyone lodges their own individual tax return, and there are no joint returns for couples. What does change how you're taxed is your residency status for tax purposes:

• Australian resident: You are taxed on your worldwide income at resident rates and get the $18,200 tax-free threshold.
• Foreign resident: You are taxed only on Australian-sourced income, at foreign resident rates with no tax-free threshold.
• Working holiday maker: Your working holiday income is taxed at 15% up to $45,000, and at higher rates above that.

Your family situation still matters: you'll need your spouse's details, including their taxable income, because they affect the Medicare levy surcharge, the private health insurance rebate and some offsets. If you're a sole trader, you still lodge an individual return and include your business income in it. Not sure about your residency? See our guide to the Australian tax residency test.

Understand Tax Deductions and Offsets

Deductions reduce your taxable income, while tax offsets reduce the tax you pay, so it's worth understanding what you may be eligible for. Common ones in 2025–26 returns include:

1. Work-Related Expenses: Expenses you've incurred to earn your income, such as tools, protective or occupation-specific clothing, work travel (not your normal trip to and from work), self-education related to your current job and working from home (the fixed rate is 70 cents per hour for 2025–26). You must have spent the money yourself, not been reimbursed, and have a record to prove it.
2. Gifts and Donations: Gifts of money to deductible gift recipients (DGRs) are deductible. The old $2 minimum no longer applies to gifts made from 1 July 2024 (this change doesn't cover political donations, which have their own rules).
3. Personal Super Contributions: If you made after-tax contributions to super and lodged a notice of intent with your fund, you may be able to claim them as a deduction (within the $30,000 concessional contributions cap for 2025–26).
4. Investment Expenses: Expenses related to earning investment income, such as interest on investment loans, may be deductible, as is the cost of managing your tax affairs, including your tax agent's fee.
5. Tax Offsets: Tax offsets, such as the low income tax offset (up to $700 if your taxable income is $37,500 or less, phasing out to nil at $66,667) or the seniors and pensioners tax offset, directly reduce the amount of tax you owe.

Coming in 2026–27: from the 2026–27 income year, eligible workers will automatically get a standard deduction of up to $1,000 for work-related expenses, with no receipts needed. It doesn't apply to 2025–26 returns, so keep claiming your actual expenses (with records) this year. See our guide to the $1,000 standard tax deduction.

Carefully review the eligibility criteria for each deduction and offset to make sure you're claiming everything you're entitled to. If you're not sure, download our tax checklist.

Medicare Levy, Private Health Insurance and HELP

• Medicare levy: Most residents pay 2% of their taxable income. You pay a reduced levy or none if your income is low (for 2025–26 the threshold for singles is $28,011), and some people can claim an exemption. See our guide to Medicare levy thresholds.
• Medicare levy surcharge: If you don't have an appropriate level of private hospital cover and your income for surcharge purposes is above $101,000 (singles) or $202,000 (families) for 2025–26, you pay an extra 1% to 1.5%. Read how to avoid the Medicare levy surcharge.
• Private health insurance: Your policy details work out whether you received the right private health insurance rebate and whether the surcharge applies, so check the pre-filled policy details and the days you were covered.
• HELP and other study loans: If your repayment income is above the minimum threshold ($67,000 for 2025–26), a compulsory repayment is calculated through your return: 15 cents for each dollar above the threshold, rising at higher incomes. See how to repay your HECS-HELP debt.

Choose Your Lodgement Method

There are several ways to lodge your tax return in Australia, each with its own advantages and considerations:

1. myTax (ATO online): Lodge free online through ATO online services in your myGov account (you'll need to link the ATO to myGov first). Pre-fill information from employers, banks, health funds and government agencies starts arriving from 1 July, and most of it is in by the end of July. See the ATO's guide to lodging with myTax.
2. Registered Tax Agent: Engaging a registered tax agent can be worthwhile if your situation is more complex. They make sure you claim everything you're entitled to, lodge on your behalf, and can give you a later lodgement deadline. Their fee is deductible in your next return.
3. Paper Return: You can still lodge on paper using the Individual tax return 2026 form from the ATO, but paper returns take much longer to process, up to 50 business days.

When choosing your lodgement method, consider your personal preferences, the complexity of your tax situation, and any potential cost savings.

How to Lodge with myTax, Step by Step

1. Set up myGov and myID: Create a myGov account at my.gov.au. The ATO recommends signing in with myID (formerly myGovID) at Standard or Strong identity strength for better security.
2. Link the ATO: In myGov, follow the prompts to link the ATO, confirm your personal details and answer the identity questions, which are based on information the ATO holds about you. If the ATO can't confirm your identity online, it will tell you what to do next.
3. Wait until your information is ready: Check that your income statement is marked Tax ready (the ATO lets you know in your myGov inbox). Most other pre-fill data, such as bank interest, dividends, private health insurance and government payments, is available by the end of July; some, like trust and partnership distributions, comes later.
4. Start your return: Select ATO from your linked services, then Manage tax returns, and prepare your 2026 return (the 2025–26 income year).
5. Check the pre-filled information: Compare it with your own records and add anything that's missing, such as rental income, capital gains, foreign income or cash work. If a pre-filled amount is wrong, check with the payer before you change it.
6. Add your deductions and offsets: Enter your work-related expenses, gifts, investment expenses and other claims, and answer the questions about offsets.
7. Complete the Medicare and private health sections: Confirm your private health insurance details and enter your spouse's details if you had one.
8. Review and lodge: Check the estimate myTax shows you, then submit. You'll see a receipt number once your return has been lodged.

Understand Key Deadlines and Dates

Staying on top of important tax deadlines and dates is crucial to ensure you lodge your return on time and avoid any penalties or late fees. Some key dates to be aware of include:

1. 30 June: The end of the financial year. Expenses generally need to be incurred by this date to be claimed in that year's return.
2. 31 October: The due date if you lodge your own return. For 2025–26 returns, 31 October 2026 falls on a Saturday, so returns lodged by Monday 2 November 2026 are on time.
3. 21 November: When any tax owing on a self-lodged return is generally due (Monday 23 November in 2026, as 21 November falls on a Saturday).
4. 15 May: The later due date (15 May 2027 for 2025–26 returns) that generally applies if you're on a registered tax agent's client list before the 31 October deadline and your earlier returns are up to date.
5. Amendments: You generally have two years from your notice of assessment to amend a return (longer in some situations).

It's important to note that the ATO may impose penalties or interest charges if you miss these deadlines, so be sure to plan accordingly.

Review and Submit Your Tax Return

Before you submit your tax return, it's essential to carefully review it to ensure all the information is accurate and complete. Double-check the following:

1. Personal Details: Verify that your name, address, tax file number, bank account and other personal information are correct.
2. Income and Deductions: Ensure all your income sources are accurately reported and that you've claimed all eligible deductions and offsets.
3. Calculations: Carefully review the estimate to make sure your tax liability and any refund amounts look right.
4. Lodgement Method: Confirm you've chosen the right lodgement method (myTax, a registered tax agent or a paper return) and followed all the necessary steps.

Once you're satisfied that your tax return is complete and accurate, you can lodge it. If you're using myTax, you submit it online, and the ATO says most online returns are processed within 12 business days (longer if a return needs a manual check). If you're working with a tax agent, they will lodge it on your behalf. See how long a tax refund takes.

Understand the ATO's Response and Next Steps

After you've lodged your tax return, you can expect to receive a response from the ATO. This may include:

1. Notice of Assessment: The ATO will issue a Notice of Assessment, which outlines your final tax liability and any refund or payment due.
2. Refund: If you're entitled to a tax refund, the ATO will process the payment and deposit the funds into your nominated bank account.
3. Tax Debt: If you owe additional tax, the ATO will provide instructions on how to make the payment, including due dates and payment options.
4. ATO Reviews: If the ATO identifies any issues or discrepancies in your tax return, it may ask for more information or adjust your return.
5. Amendments: If you spot a mistake, you can amend your return once the original has been processed. In ATO online services, select Manage tax returns, then Amend next to the year you want to change. The time limit is generally 2 years from your notice of assessment.

It's important to carefully review the ATO's response and take any necessary action, such as making a payment or providing additional documentation. Staying on top of these steps will help ensure a smooth tax season and avoid any potential penalties or issues.

Conclusion

How do I get help with this from the ATO?

The ATO provides guidance through ato.gov.au, the Small Business Support Line (13 28 66), and Online Services for individuals and businesses. For complex situations, a registered tax agent provides advice tailored to your specific circumstances and professional indemnity protection. You can verify agent registration at the TPB register at tpb.gov.au. See our guide to ATO tax return help.

What records do I need to keep for tax purposes in Australia?

Most tax records must be kept for five years from the date of lodgement or the date the transaction occurred, whichever is later. Records must be in English or convertible to English and must be sufficient to explain the income and deductions in your return. The ATO can request records at any time during the retention period.

When do I need a registered tax agent in Australia?

Consider a registered tax agent when your affairs involve multiple income sources, business activity, investment properties, capital gains, or overseas income. Agents extend your lodgement deadline, provide safe harbour protection, and take professional responsibility for the advice given. Verify registration at tpb.gov.au.

How does the ATO calculate penalties for compliance failures?

The failure to lodge penalty is calculated in Commonwealth penalty units (the dollar value is indexed periodically, so check the ATO for the current figure). One unit applies for each 28-day period a return or BAS is late, up to five units for individuals and small businesses, and more for larger entities. Incorrect information penalties range from 25% to 75% of the tax shortfall depending on whether the behaviour was careless, reckless or intentional. Telling the ATO before an audit begins typically results in significantly reduced penalties.

What is the difference between tax avoidance and tax minimisation?

Tax minimisation is the legal arrangement of your affairs to reduce tax — claiming all eligible deductions, using appropriate structures, and timing income and expenses. Tax avoidance involves arrangements that technically comply with the law but achieve outcomes parliament did not intend. The ATO can apply Part IVA anti-avoidance rules to cancel benefits from avoidance arrangements.
