Lodging your annual tax return in Australia: myTax, refunds, agents

The Australian tax system runs on a financial year from 1 July to 30 June. After the financial year ends, most people who earn income need to lodge a tax return — declaring their income and getting back any tax they overpaid (or paying more if they underpaid). This is an annual process you will repeat every year in Australia.

Who needs to lodge a tax return?

Most people who earned income in Australia during the financial year need to lodge a tax return. Even if you only worked part of the year, or your income was below the tax-free threshold, in many cases you still need to lodge — either to receive a refund or to confirm to the ATO that you have no further tax obligation.

If you are not sure whether you need to lodge, the ATO has an online tool to check at ato.gov.au.

PAYG withholding — tax taken out in advance

If you are an employee, your employer automatically withholds tax from your pay each pay cycle and sends it to the ATO — this is called PAYG withholding (Pay As You Go). You do not have to pay tax yourself each month.

At the end of the financial year, the ATO compares the total tax withheld with the tax you should actually have paid:

• If too much was withheld → the ATO refunds the difference (a tax refund)
• If too little was withheld → you have to pay more (a tax debt)

Common reasons for over-withholding: your employer calculated at a higher rate, you actually earned less than expected, or you have valid deductions.

myTax — how to lodge online

myTax is the ATO’s free online lodgement tool, accessed through your myGov account. This is how most Australians lodge their personal tax return — no separate software, no fee.

myTax’s strength is pre-filling. The ATO automatically fills in much of the information for you:

• Income from your employer (from your Payment Summary / Income Statement)
• Bank interest income
• Amounts from Centrelink (if any)
• Health insurance information

You check it, add anything that is missing (deductions, other income), and then submit. The ATO usually processes returns within a few weeks and notifies you through your myGov inbox.

Deductions — valid amounts you can claim

Deductions reduce your taxable income, which in turn reduces the tax you owe (or increases your refund). Some common deductions:

Work-related expenses:

• Specific uniforms or protective clothing (not ordinary clothes)
• Study costs directly related to your current job
• Tools and equipment you paid for yourself
• Home office expenses — these have their own calculation rules

Other amounts:

• Tax management fees (a tax agent fee from the previous year)
• Donations to DGR-registered organisations
• Investment costs (if you have investment income)

The principle: a deduction must relate directly to earning your income, you must have genuinely paid for it (not been reimbursed by your employer), and you must have a receipt to prove it.

When should you use a tax agent?

A tax agent (a tax agent registered with the ATO) can lodge on your behalf and has a longer deadline than lodging yourself. This suits you when:

• Your tax situation is complex: multiple income sources, investment income, a rental property
• It is your first year in Australia: you are not sure what to declare
• You do not have the time, or do not want to do it yourself

A tax agent charges a fee — but that fee is deductible in the following tax year. Find a registered tax agent at ato.gov.au/tax-professionals.

Tax and newcomers to Australia

If you arrive in Australia partway through the financial year and start working, you still have to lodge a tax return for that year. The first year is often harder because you are not yet familiar with the system — many people choose to use a tax agent for their first year and do it themselves from the second year onwards.

The ATO also runs a Tax Help program — ATO-trained volunteers who help people on low incomes lodge their tax for free. It suits newcomers, students, and anyone unfamiliar with the system.

You access myTax through your myGov account — if you do not have myGov yet, see the related guide on setting up and using myGov, Australia’s government services portal.
