Missed A Tax Deadline? Here’s How To Dodge Massive ATO Penalties

Late lodging your tax return or business activity statement (BAS) in Australia can cost you more than you think. The Australian Taxation Office (ATO) imposes Failure to Lodge (FTL) penalties, which can add up quickly, especially for businesses and trusts. The good news? There are ways to avoid or reduce these penalties, even if you’ve already missed a deadline.

This article will explain what late lodgment penalties are, how they work, who they apply to, and most importantly ,how to minimise them.

What is a Late Lodgment Penalty?

When you don’t lodge your tax return, BAS, or other ATO-required documents by the due date, the ATO may charge you a Failure to Lodge (FTL) on time penalty. This is the formal name for what most people simply call a late lodgment penalty.

The penalty is designed to encourage timely compliance, but it’s not automatically applied every time. The ATO considers your circumstances before issuing the penalty.

Who Can Be Hit with a Late Lodgment Penalty?

Late lodgment penalties can apply to:

• Individuals
• Companies
• Trusts
• Superannuation funds
• Partnerships

Whether you are an individual forgetting to lodge your personal return or a business missing a BAS, the penalty regime applies broadly.

How Are Late Lodgment Penalties Calculated?

The Penalty Unit System

The penalty is calculated using a system called Penalty Units. As of March 2025, one penalty unit equals $313.

The penalty is calculated as:

• 1 penalty unit for every 28 days (or part thereof) the return is late, up to a maximum of 5 penalty units.

Total Maximum Penalties

The longer you wait, the more it costs.

How Does the ATO Apply Penalties?

The ATO may issue an FTL penalty if:

• You fail to lodge by the due date
• Your lodgment is still outstanding when the ATO checks

However, it’s not automatic. The ATO takes into account:

• Your lodgment history
• Your compliance behaviour
• The reasons for delay

For example, if you usually lodge on time and missed one deadline due to illness or a natural disaster, the ATO may waive the penalty.

Ways to Minimize or Avoid Late Lodgment Penalties

1. Lodge As Soon As Possible

Even if you’ve already missed the due date, lodging today can limit the penalty to the minimum. Penalties grow with every 28-day period, so each day counts.

2. Engage a Registered Tax Agent

Tax agents get concessional lodgment dates. This means your due date may be later than the standard one if you’re on their client list before the original due date.

Also, agents can often negotiate on your behalf if penalties have already been applied.

3. Request Penalty Remission

The ATO has the discretion to reduce or fully remit penalties if you have a valid reason. Common grounds include:

• Serious illness
• Natural disasters
• Genuine mistakes
• System outages

You or your tax agent can submit a penalty remission request explaining the situation.

4. Stay in Good Lodgment Habits

Entities with a clean record are less likely to be penalised for a one-off late lodgment. Developing good habits ,such as diarising due dates and automating reminders, can protect you from future penalties.

5. Consider a Voluntary Disclosure

If you realise you’ve missed a lodgment but the ATO hasn’t yet contacted you, you may benefit from making a voluntary disclosure. This shows good faith and may reduce penalties.

Common Scenarios

Individual Example

Jane, a sole trader, missed lodging her 2024 tax return. She is two months late. Because she is more than 28 days late but less than 56 days, she is charged 2 penalty units ($626). By lodging immediately, she avoids further units being added.

Business Example

XYZ Pty Ltd, a small business with turnover under $10 million, forgot to lodge its BAS for three months. This resulted in the maximum of 5 units ($1,565) being applied. However, because XYZ engaged a tax agent who explained that the business suffered a cyberattack, the ATO agreed to remit the penalty.

What Happens If You Ignore the Penalty?

Ignoring the penalty won’t make it go away. In fact, unpaid penalties can accrue general interest charges (GIC), making your debt grow even more. The ATO can also take stronger collection actions like garnishee notices or legal proceedings.

Tips to Stay on Track

• Use a tax agent to access extended lodgment dates
• Register for ATO online services and set up reminders
• Keep records updated throughout the year
• Don’t ignore ATO letters or notices ,act early

Final Thoughts

Late lodgment penalties are avoidable and manageable if you act early and engage proactively. Whether you are an individual or a business owner, understanding how the penalties work ,and how to reduce or even waive them ,can save you stress and money.

If you’re unsure about your position or need help negotiating with the ATO, consider speaking to a registered tax agent. Their expertise often pays for itself, especially when dealing with penalty remission.
