Receiving a notification from the Australian Taxation Office (ATO) is rarely a welcome event, particularly when it concerns a late tax return penalty. The official term for this is a Failure to Lodge (FTL) penalty, a fine the ATO imposes when your tax documents are not submitted by the official deadline. This isn’t an arbitrary charge; it’s a structured mechanism designed to ensure timely compliance from all taxpayers, especially those with a tax liability.
How ATO Late Lodgement Penalties Actually Work

A penalty notice can be a source of significant stress, but understanding the mechanics behind it is the first step toward taking decisive action. The FTL penalty is not designed to be purely punitive. Instead, view it as a formal reminder—a nudge from the ATO to uphold your tax responsibilities and maintain the integrity and fairness of the tax system for everyone.
Crucially, these penalties are typically reserved for situations where you have a tax debt. If you lodge your return late but are due a refund or have a ‘nil’ balance, the ATO will generally not issue a penalty. Their primary objective, after all, is the timely collection of owed tax revenue. If you’re unsure of your tax position, it’s critical to act now to avoid escalating issues.
Actionable Tip: Don’t delay. Lodge your overdue return immediately, even if you can’t pay the associated tax bill. Lodging stops the penalty clock and demonstrates your intent to comply, which is the first step in resolving the situation.
The Penalty Unit System Explained
So, how does the ATO determine the penalty amount? The calculation is based on a standardised system of penalty units.
For the 2024-25 financial year, one penalty unit is valued at $330. The ATO applies one unit for every 28-day period (or part thereof) that your return is overdue. For most individuals and small businesses, these penalties accumulate until they reach a statutory cap.
The bottom line: For an individual or a small business, the penalty is capped at a maximum of five penalty units. At the current rate, that totals $1,650. The final amount depends on your entity’s size and, most importantly, the duration of the delay.
ATO Penalty Unit Rates at a Glance
To provide absolute clarity, this table outlines how penalties are calculated based on your entity’s size. The fine is applied for each 28-day period your lodgement is late, up to a maximum of five periods.
| Entity Size | Penalty Per 28-Day Period | Maximum Penalty (5 Periods) |
|---|---|---|
| Small Entity | 1 penalty unit | 5 penalty units |
| Medium Entity | 2 penalty units | 10 penalty units |
| Large Entity | 5 penalty units | 25 penalty units |
| Significant Global Entity | 500 penalty units | 2,500 penalty units |
This table clearly demonstrates why meeting your lodgement deadlines is so critical—the financial consequences can escalate rapidly, particularly for larger organisations.
Staying organised is your most effective defence against these fees. Many professionals leverage dedicated software to ensure timely and accurate filing; for example, high-quality Drake Tax hosting solutions can help streamline the entire process.
If you’ve received a penalty notice, do not ignore it. The most effective course of action is to lodge the overdue return and open a line of communication with the ATO (or your tax agent). This is the most critical step to mitigate further financial damage.
How Does the ATO Actually Calculate Your Penalty?
Have you ever examined a penalty notice from the ATO and questioned the origin of the figure? It’s not an arbitrary number; a precise formula is at work. The Australian Taxation Office employs a structured system built around the concept of a penalty unit. Grasping this concept is the first step to understanding exactly what you’re being charged for.
Consider a penalty unit as the foundational building block for fines. The government sets its dollar value, which is periodically adjusted to reflect economic changes and maintain its effectiveness as a deterrent. The value has steadily increased, signalling the ATO’s firm stance on timely lodgements.
Observe the recent increases: the rate was $222 between July 2020 and December 2022. It then rose to $275 in early 2023, and again to $313 on 1 July 2023, before reaching the current rate of $330 on 1 July 2024.

The Two Key Ingredients in Your Penalty Calculation
When the ATO calculates your penalty, it hinges on two primary factors:
- How late you are: The penalty is applied for every 28-day block (or part of a block) that your document remains unlodged.
- How big your business is: The ATO scales the penalty based on your assessable income or turnover, classifying you as a small, medium, or large entity.
This structure is designed for fairness and proportional impact. A large corporation faces a much steeper penalty for the same delay than a sole trader, ensuring the financial consequence is relative to the entity’s scale.
How a Small Overdue Bill Can Snowball
The penalty isn’t a single charge; it accumulates. For every 28 days your return remains outstanding, another penalty unit (or multiple units, depending on your business size) is added to your debt. This continues until it reaches a legislative cap.
For small entities—which includes most individuals and small businesses—the penalty maxes out at five penalty units. While a cap exists, the fine can still amount to a significant sum if neglected.
A Practical Example: A Small Business
Let’s analyse a common scenario. A small business with a turnover under $1 million has failed to lodge its tax return and is now 60 days late. Here is how the ATO would calculate the penalty:
- Period 1 (Days 1-28): The first block triggers 1 penalty unit.
- Period 2 (Days 29-56): A second block passes, adding another unit. Total is now 2 penalty units.
- Period 3 (Days 57-60): You have entered a new 28-day block. Even a few days into this block triggers a full penalty. The total becomes 3 penalty units.
The total damage? Three penalty units. At the current rate of $330 per unit, this results in a $990 late lodgement penalty. This clear calculation demystifies the final figure on your notice.

Seeing the Real-World Cost of Late Lodgement
Theory is one thing, but what does a late lodgement penalty actually look like in dollars and cents? Seeing how the numbers stack up in real-world situations really brings home the financial risk of putting off your tax obligations. The cost of doing nothing adds up fast.
Let’s walk through a few common scenarios to see how the ATO’s penalty framework translates into tangible costs.
Example 1: The Sole Trader
Picture a sole trader who is 90 days late lodging their annual tax return. As a ‘small entity’ in the eyes of the ATO, their penalty is based on one penalty unit for every 28-day block (or part thereof) that the return is overdue.
Here’s how it unfolds:
- Days 1–28: The first 28-day period passes. That’s 1 penalty unit.
- Days 29–56: The second period goes by, adding another unit. Total: 2 penalty units.
- Days 57–84: A third period concludes. The total is now 3 penalty units.
- Days 85–90: Since the return is still not lodged, a fourth 28-day block has started. This immediately triggers another unit, bringing the total to 4 penalty units.
With the current penalty unit rate at $330, this 90-day delay costs the sole trader $1,320 (4 units x $330). It’s a steep price for a three-month delay.
Example 2: The Medium-Sized Business
Now, let’s look at a medium-sized business—one with an annual turnover between $1 million and $20 million. For these entities, the ATO doubles the penalty rate.
If this business is also 90 days late, the calculation gets a lot more serious:
- For each 28-day period, the penalty is 2 penalty units, not one.
- Over the same 90-day delay (which covers four penalty periods), the business racks up 8 penalty units (4 periods x 2 units).
- The final bill? A hefty $2,640 (8 units x $330).
This shows how the late tax return penalty is scaled. The bigger your operation, the bigger the immediate financial hit.
This chart breaks down the core idea of how these penalties build up over time.

As you can see, penalties accumulate in set blocks up to a maximum cap. This design really drives home the need to lodge as soon as you can to avoid reaching that ceiling.
To make this even clearer, the table below compares how penalties grow for different entities side-by-side.
Penalty Calculation Scenarios
| Entity Type | Days Overdue | Penalty Calculation | Total Penalty |
|---|---|---|---|
| Small Entity | 35 days | 2 penalty units x $330 | $660 |
| Medium Entity | 35 days | 2 periods x 2 units/period = 4 penalty units x $330 | $1,320 |
| Large Entity | 35 days | 2 periods x 5 units/period = 10 penalty units x $330 | $3,300 |
| Significant Global Entity | 35 days | 2 periods x 500 units/period = 1,000 penalty units x $330 | $330,000 |
This comparison really highlights the dramatic difference in financial consequences based on your entity’s size. What’s a manageable (though still painful) fine for a sole trader quickly becomes a major liability for a larger company.
Key Takeaway: The penalty system is built to create urgency. The longer you wait, the more it costs—and for bigger businesses, those costs are multiplied from day one.
These examples make it obvious: putting off your tax duties has a direct and predictable financial consequence. The system is automated, and the fines will keep ticking up until you take action.

When the ATO Might Waive Your Penalty

Receiving a Failure to Lodge (FTL) penalty notice is a serious matter, but it is not always the final word. The Australian Taxation Office (ATO) has provisions to cancel, or ‘remit’, a penalty under circumstances of genuine hardship. This is not about disagreeing with the fine; it is about demonstrating that events beyond your control prevented you from lodging on time.
The ATO can be reasonable if you have a legitimate reason for the delay. The key is to understand what constitutes a valid reason and how to substantiate your claim with credible evidence. This knowledge transforms a daunting problem into a manageable situation with a clear path to resolution.
Ultimately, having a late tax return penalty waived hinges on proving you had a ‘reasonable excuse’. This is a specific legal standard. It does not cover disorganisation or forgetting a deadline; it refers to a significant event that made it practically impossible to meet your tax obligations.
Common Grounds for Penalty Remission
So, what reasons does the ATO consider valid? While each case is assessed on its own merits, several common scenarios are more likely to be accepted.
These generally fall into a few key categories:
- Serious illness or accident: A major medical emergency involving yourself or a close family member that understandably consumed your time and focus.
- Natural disaster: Events like floods, bushfires, or cyclones that directly impacted your home, business, or destroyed essential financial records.
- Death of a key person: The loss of a close family member, a business partner, or a company director can constitute a valid reason for delay.
- Delay caused by your tax agent: If your registered tax agent was unable to lodge on your behalf due to their own illness or another unforeseen issue, this may also be considered.
It’s crucial to be realistic. Being busy at work or misreading a due date will not be accepted. The circumstances must be genuinely serious and have a direct causal link to your failure to lodge.
Key Insight: The success of your remission request depends almost entirely on the quality of your evidence. It’s not enough to just state you were ill. You need to provide proof, like a doctor’s certificate, hospital records, or a statutory declaration, to build a credible case.
Proving Your Case to the ATO
Before requesting a remission, you must lodge the overdue return. This is a non-negotiable step that demonstrates your commitment to rectifying the situation. Once lodged, you need to provide a clear, honest, and well-documented explanation for the delay. If the penalty is part of a broader issue, it can be beneficial to understand all your options for navigating tax disputes to engage with the ATO effectively.
Think of it as presenting a case backed by facts. You must connect the dots for the ATO, showing precisely how a specific event prevented you from lodging on time. The clearer your explanation and the stronger your documentation, the higher your likelihood of a positive outcome.
Actionable Tip: Don’t face the ATO alone. If you believe you have a valid reason for a waiver, Book a consultation today. Our expert accountants can help you gather the necessary evidence, structure your argument, and communicate effectively to achieve the best possible result.
Your Action Plan for Requesting a Penalty Waiver
Identifying a valid reason for a penalty waiver is the first step; securing it is the next. Let’s outline the practical steps for formally requesting a remission from the Australian Taxation Office (ATO). Whether you handle this yourself or engage your accountant, a structured and professional approach is essential for success.
Before drafting a letter or making a call, adhere to the golden rule: you must lodge the overdue return first. The ATO will not consider a remission request until your primary obligation to file is met. Lodging is a non-negotiable demonstration of good faith.
How to Officially Request a Remission
With your outstanding documents lodged, you can formally present your case. The most effective method of communication depends on your circumstances and comfort level with the tax system.
You can request a remission:
- Through your registered tax agent: This is often the most strategic choice. Your agent understands the system, can submit requests via dedicated online portals, and knows how to frame the argument for the highest probability of success.
- Via your myGov account: If you manage your own tax affairs, you can submit a request directly through myGov by logging into the ATO’s online services and using the “request for remission” function.
- By phoning the ATO: You can call the ATO directly to state your case. Ensure you have all relevant details, dates, and supporting evidence organised before you call.
Structuring Your Request for Success
When presenting your case, clarity and honesty are paramount. It is not sufficient to merely state an excuse; you must construct a compelling narrative that connects the events to your failure to lodge.
Frame your request as a clear, respectful explanation. Show how specific circumstances directly prevented you from lodging. For example, instead of saying, “I was sick,” explain that, “A serious medical emergency required hospitalisation from [Date] to [Date], and as a result, I was physically unable to access my records to prepare and lodge my return.”
Your explanation must always cover these four points:
- The specific reason for the delay: Clearly name the event (e.g., serious illness, natural disaster).
- The timeline: Provide exact dates and show how they coincide with the tax deadline.
- The connection: Explicitly state how this event made it impossible for you to lodge.
- Supporting evidence: This is critical. Attach documents like a doctor’s certificate, insurance claim, or a statutory declaration to substantiate your claims.
This proactive approach is increasingly common. Penalty remission requests have risen by 15% in recent years, indicating that more taxpayers are engaging with the ATO to resolve penalties stemming from genuine hardship. To learn more about successful strategies for managing late returns, you can review recent compliance trends on itp.com.au.
It’s also worth noting that the ATO manages other penalty types with similar principles. Business owners should also understand how to avoid superannuation guarantee payment penalties, which are based on the same principles of compliance and potential remission.

Answering Your Top Penalty Questions

Being issued a late tax return penalty is a stressful experience that naturally raises numerous questions. Obtaining clear, expert answers is the best way to determine your next steps and alleviate uncertainty. Let’s address some of the most common queries from taxpayers facing a Failure to Lodge (FTL) penalty.
Will I Get a Penalty If I Am Due a Tax Refund?
This is one of the most frequent and critical questions. In short, it is unlikely. The ATO generally does not apply an FTL penalty if your late tax return results in a refund or a ‘nil’ balance (where no tax is owed or due).
The purpose of the penalty system is to ensure the timely collection of government revenue. If you do not owe tax, the primary motivation for penalising you is removed. However, you still have a legal obligation to lodge the return to remain compliant.
How Will I Know If I Have a Penalty?
The ATO communicates penalties formally and directly. You will receive an official penalty notice, delivered either to your myGov inbox or by post to your last known address.
This notice will clearly state:
- The reason for the penalty (e.g., Failure to lodge on time).
- The exact penalty amount.
- The payment due date.
It is imperative to address this notice immediately upon receipt.
Can My Tax Agent Get the Penalty Waived for Me?
Yes, absolutely. In many instances, having your registered tax agent request a remission (waiver) is the most effective strategy. Your accountant has access to dedicated ATO communication channels, such as professional online portals.
They possess the expertise to frame the request, gather the appropriate evidence, and present your case in a manner that aligns with ATO guidelines. This professional intervention can significantly increase your chances of having the penalty reduced or cancelled entirely.
What Happens If I Ignore the Penalty Notice?
Ignoring a penalty notice is the worst possible course of action. The debt will not disappear. It becomes a legally enforceable debt to the ATO and will begin to accrue a General Interest Charge (GIC), increasing the total amount you owe over time.
If you continue to ignore it, the ATO has significant powers to collect the debt. This can include garnishing your wages, seizing funds directly from your bank account, or referring your case to an external debt collection agency. Always respond to ATO correspondence.
Maintaining compliance is essential. For further expert advice on ATO dealings and preparedness, you can find valuable external resources that explain how to prepare for an audit, which provide practical insights into tax compliance.
These answers should provide the clarity needed to move forward. While a penalty is serious, you have options. The crucial first step is to act: lodge the return, assess your position, and communicate with the ATO or your tax professional.
