What is the deadline for lodging tax returns in Australia? And What do I do if I miss the due date?

If you're lodging your tax return yourself, the deadline is October 31 for the financial year from July 1 to June 30. If you use a tax agent, you may be eligible for an extended deadline, which can be as late as May 15, depending on your situation. However, you must contact a tax agent before October 31, make sure the tax agent adds you as their client by the due date.

If you miss the due date, it is important to lodge as soon as you can. If you expect a tax bill, don't delay lodging because you may be liable to a late lodgement penalty. It may apply of $313 per 28 days late and interest charge for the amount you pay late.

Do the ATO check every tax return?

Yes, the ATO checks all tax returns using automated systems, which verify basic details against information from employers and other sources.

If a return seems unusual, it’s reviewed further by ATO staff. They prioritize returns based on risk, focusing on those most likely to have errors.

Each year, the ATO conducts tens of thousands of audits on individuals and businesses to ensure compliance with tax laws and fairness in the system.

Can ATO see my bank account?

Yes, the ATO can directly request information from banks under its statutory powers. This includes:

Section 264 of ITAA 1936: Grants the ATO the power to obtain information, documents and evidence from taxpayers and third parties, inluding banks.

Section 353-10 of TAA 1953: Authorises the ATO to require any person to provide information, attend an interview, or produce documents for tax administration purposes.

While the ATO’s access to bank account information is legally but they still need to issues a formal notice and is bound by strict confidentially provisions, ensuring that taxpayer information is protected and only used for tax administration purposes.

What is work related I can claim for my individual tax return?

To claim a deduction for work‑related expenses, you must have spent the money yourself and not been reimbursed; the expense must be directly related to earning your income and you must have a record to prove the expense.

Some work related you can claim:

· Work related car expenses

· Work related travel expenses

· Work related clothing, laundry and dry-cleaning expenses

· Work related self-education expenses

· Other work related expenses: union fees, subscriptions, professional associations, overtime meal expenses, reference books, magazines, safety items, working from home, work related portion of telephone, work related portion of tools and equipment, computer, office furniture.

· Depreciation of assets that use to producing assessable income

· Interest and dividend deductions such as bank fees for investment

· Gifts or donations

· Accountant fee or cost of managing tax affairs

How long to keep the records for work related deduction?

You need to keep your records for 5 years from the date you lodge your tax return.

If you claim the decline in value of a depreciating asset that you use for work, keep records for 5 years from the date of your last claim for the decline in value.

If the total amount you are claiming is $300 or less, you need to be able to show how you worked out your claims, but you don’t need written evidence.

Do I need to declare my spouse’s income on my tax return? And What happen if my spouse is a foreign resident?

Yes, you'll both need to include each other's total taxable income for the year and enter the relevant dates you are married if it is not in full financial year. ATO need your spouse information to calculate correct your Medicare levy or Medicare levy surcharge, pensioner tax offset and private health insurance rebate.

Even if your spouse is a foreign resident for tax purposes, you need to declare that you have a spouse. You also need to include their global income in the spouse income disclosures on your tax return.

What will I do if I can’t pay my debt on time to ATO?

If you don't pay on time, ATO will automatically add a general interest charge (GIC) to what you owe overdue. Interest calculates on a daily compounding basis on the amount overdue and is added to your account periodically.

If you're experiencing financial difficulties and you can’t pay on time, you should contact ATO as soon as possible to request support from ATO to set up a manageable payment plan to pay down your debt.

Or you can ask your accountant to help you negotiate with the ATO on your behalf.
