Tax time

April 1, 2025

Navigating the Australian tax system is essential for both individuals and businesses to ensure compliance and avoid penalties. Here's a straightforward guide to the key tax categories and their respective lodgment deadlines.​

Personal Taxes

In Australia, personal income tax is levied on an individual's taxable income, which includes wages, salaries, and other earnings. The tax system is progressive, meaning the rate increases as income rises. The financial year runs from 1 July to 30 June. If you're lodging your tax return yourself, the deadline is 31 October following the end of the financial year.For example, for the 2024–2025 financial year, you must lodge by 31 October 2025. If you use a registered tax agent, you may have extended deadlines, but it's important to engage them before 31 October to qualify for these extensions. ​ 


Business Taxes

Businesses in Australia are subject to various taxes, including income tax, Goods and Services Tax (GST), and Pay As You Go (PAYG) withholding. The type of business structure—sole trader, partnership, trust, or company—affects tax obligations and deadlines.​

  • Sole Traders, Partnerships, and Trusts: These entities typically align with individual tax deadlines. Tax returns are due by 31 October each year unless lodging through a registered tax agent, which may allow for extended deadlines. ​
  • Companies: Company tax returns are generally due by the 15th day of the seventh month following the end of the income year. For example, for a company with a standard financial year ending on 30 June, the tax return would be due by 15 January of the following year. However, if lodging through a registered tax agent, this date may be extended. ​ 

Business Activity Statements (BAS)

Businesses registered for GST must lodge Business Activity Statements to report and pay various tax obligations, including GST, PAYG installments, and other taxes. BAS is usually lodged quarterly, with due dates as follows:​

  • Quarter 1 (July–September): 28 October​ 
  • Quarter 2 (October–December): 28 February​
  • Quarter 3 (January–March): 28 April​ 
  • Quarter 4 (April–June): 28 July​

If any due date falls on a weekend or public holiday, you can lodge or pay on the next business day without incurring penalties. ​


Fringe Benefits Tax (FBT)

If your business provides fringe benefits to employees, such as company cars or low-interest loans, you may be liable for Fringe Benefits Tax. The FBT year runs from 1 April to 31 March, with returns typically due by 21 May. However, if lodging through a tax agent, you may have until 25 June. ​ 

Key Points to Remember

  • Engage Early: If you plan to use a tax agent, contact them before 31 October to access potential lodgment extensions.​
  • Stay Informed: Tax laws and deadlines can change. Regularly check the ATO website or consult with a professional to stay updated.​
  • Meet Deadlines: Late lodgment or payment can result in penalties and interest charges. Mark key dates in your calendar to ensure timely compliance.​

By understanding your tax obligations and adhering to the relevant deadlines, you can navigate the Australian tax system more effectively and avoid unnecessary complications.​

​Failing to lodge required tax documents with the Australian Taxation Office (ATO) by the due date can lead to significant penalties and interest charges. Understanding these consequences is crucial for both individuals and businesses to maintain compliance and avoid financial setbacks.​


Failure to Lodge (FTL) on Time Penalty

The ATO imposes an FTL penalty when tax returns, activity statements, or other required documents are not submitted by their respective deadlines. The penalty is calculated based on the size of the entity and the length of the delay:​ 

  • Small Entities: For individuals and small businesses (assessable income or GST turnover under $1 million), the penalty accrues at one penalty unit for each 28-day period (or part thereof) the document is overdue, up to a maximum of five penalty units.​
  • Medium Entities: For entities with assessable income or GST turnover between $1 million and $20 million, the penalty is multiplied by two.​
  • Large Entities: For those with assessable income or GST turnover of $20 million or more, the penalty is multiplied by five.​

As of 1 July 2024, each penalty unit is valued at $313. Therefore, for a small entity, the penalties would be:​

  • 1–28 days late: $313​
  • 29–56 days late: $626​ 
  • 57–84 days late: $939​
  • 85–112 days late: $1,252​ 
  • 113–140 days late: $1,565​

The maximum penalty for a small entity is $1,565.​


General Interest Charges (GIC)

In addition to the FTL penalty, the ATO may apply General Interest Charges on any outstanding tax debts. These charges accrue daily until the debt is settled, compounding the amount owed over time.​

Prosecution Actions

Persistent failure to lodge required documents can escalate to prosecution. Conviction may result in additional fines and/or imprisonment for up to 12 months. The ATO typically issues warnings before initiating such actions, emphasizing the importance of addressing overdue lodgments promptly.​

Requesting Remission

If you've received an FTL penalty, you can request a remission by demonstrating extenuating circumstances, such as natural disasters or serious illness. The ATO has the discretion to reduce or waive penalties based on individual situations.​ 

Safe Harbour Provisions

Engaging a registered tax agent or BAS agent can offer protection under safe harbour provisions. If you provided all necessary information to your agent on time, and the agent's failure to lodge was not due to recklessness or intentional disregard of the law, you may not be liable for the FTL penalty.​ 

Timely lodgment of tax documents is essential to avoid penalties and interest charges. If you're unable to meet a deadline, proactively communicating with the ATO or seeking assistance from a registered tax agent can help manage your obligations and potentially mitigate penalties.​
