Amended Tax Return Australia
Fix Past Mistakes and Lodge Overdue Returns Without the Stress
Made an error on a previous return and need to fix it? Years behind on lodgements? Both situations are more common than most people realise, and both are fixable. The most important thing you can do is act. The ATO treats voluntary disclosure far more favourably than compliance action it initiates.
We dig deep to claim every dollar you're entitled to—so nothing’s left behind.

- Two Situations, One Solution
Two Different Situations We Help With
This page covers two related but distinct situations. Understanding which one applies to you helps us prepare your engagement correctly.
You Lodged a Return That Contains Errors
This is an amended tax return. You have already lodged for a given year but something was wrong or incomplete — missed deductions, omitted income, incorrect figures, or entitlements not claimed. An amendment corrects the original return and may result in an additional refund or an additional liability.
You Never Lodged for One or More Years
This is an amended tax return. You have already lodged for a given year but something was wrong or incomplete — missed deductions, omitted income, incorrect figures, or entitlements not claimed. An amendment corrects the original return and may result in an additional refund or an additional liability.
Whichever situation applies, voluntary action always produces a better outcome than waiting for the ATO to contact you. Our registered tax agents manage the entire process on your behalf.
- Amended Returns
How to Amend a Tax Return in Australia
If you have realised your lodged return contained an error or that you missed claiming something you were entitled to, the correct course of action is to lodge an amended assessment with the ATO.
The Amendment Window
Individuals and small businesses generally have two years from the date of the original assessment notice to lodge an amendment. For larger companies, the window is four years. After these periods, the ATO has discretion to refuse an amendment unless fraud or evasion was involved. If you suspect an error in a return lodged two or more years ago, acting promptly is important. Our tax agents assess which years are still within the amendment window and prioritise accordingly.
Approaching the two-year window? Contact us as soon as possible. Once the window closes, your options narrow significantly.
What Can Be Amended
- Missing deductions not claimed in the original return
- Income that was incorrectly reported — overstated or understated
- Offsets and rebates that were not applied
- Incorrect capital gains calculations
- Rental property expenses that were omitted
- Errors in depreciation schedules
- Incorrect income splitting or trust distributions
What Happens When You Amend
- Once the ATO processes your amended return, it will issue a revised assessment. If the amendment results in a higher refund, the additional amount will be paid to you. If it results in a higher liability, the difference will be payable along with any applicable interest for the period the shortfall was outstanding.
Voluntary amendments generally attract lower penalties than errors the ATO discovers independently. Coming forward is always the better course of action.
- LATE TAX RETURNS
Overdue Returns and How to Get Compliant
If you have one or more overdue tax returns in Australia, you are not alone and the situation is not as difficult to resolve as many people assume. The ATO requires all outstanding returns to be lodged, but the process of getting compliant is straightforward when handled by a registered tax agent.
The reasons people fall behind on lodgements are varied. Life events, confusion about lodgement obligations, misplaced paperwork, financial stress, and simply not knowing where to start are all common. Whatever the reason, the most damaging thing you can do is continue to delay.
Failure to lodge on time attracts a Failure to Lodge (FTL) penalty from the ATO. The penalty is currently calculated at one penalty unit for every 28 days the return is overdue, up to a maximum of five penalty units. For individuals, one penalty unit is $313. For businesses, higher multipliers apply.
Interest can also accrue on any tax owing from prior years. The longer you wait, the more accumulated charges build up. Addressing your overdue tax return in Australia promptly minimises the total liability.
The ATO has formal mechanisms for dealing with taxpayers who come forward voluntarily. In many cases, penalties for overdue returns can be reduced or remitted entirely when a taxpayer proactively engages and lodges outstanding returns. Our registered tax agents manage this engagement with the ATO on your behalf, which significantly improves the outcome in the vast majority of cases.
It is worth noting that a significant proportion of overdue tax returns result in a refund. Tax is often withheld from wages throughout the year at a higher rate than the actual liability. If you have been delaying because you assumed you owed money, it is worth letting us review your situation before making that assumption.

- FAQ
Frequently Asked Questions
1. How long do I have to amend a tax return in Australia?
Individuals and small businesses generally have two years from the date of the original assessment to lodge an amendment. The clock starts from when the ATO issues your assessment notice, not when you lodged. If you are approaching or past this window, contact us as soon as possible to assess whether an amendment is still possible and what your options are.
2. Will I get in trouble for amending my tax return?
Not if the amendment is voluntary. The ATO actively encourages taxpayers to come forward and correct errors. Voluntary amendments generally attract no penalties or reduced penalties. The risk of getting in trouble increases significantly if the ATO identifies the error independently before you correct it. Amending proactively is always the better approach.
3. What is the penalty for a late tax return in Australia?
The Failure to Lodge (FTL) penalty is one penalty unit for every 28 days the return is overdue, up to five penalty units. For individuals, each penalty unit is currently $313, giving a maximum base penalty of $1,565 per return. For medium and large businesses, higher multipliers apply. Penalties can be reduced or remitted through voluntary disclosure and by demonstrating reasonable circumstances for the delay.
4. I have not lodged for several years. Where do I start?
The most important first step is to engage a registered tax agent and disclose the situation. We assess all outstanding years, determine which income information is still available from the ATO’s pre-fill data, prepare each return accurately, and lodge them in the most strategic order. Starting is always the hardest part. Once you engage us, we manage everything.
5. Will lodging an overdue return result in a big tax bill?
Not necessarily. Many overdue tax returns in Australia result in a refund because PAYG withholding from employment often exceeds the actual tax liability for the year. Even in cases where a liability exists, the total amount owed including penalties and interest is often significantly less than people fear. A free consultation lets us estimate the likely outcome before you commit to proceeding.
6. Can the ATO refuse to accept an amendment or late lodgement?
The ATO can refuse an amendment lodged outside the two-year window unless special circumstances apply. For late returns, the ATO cannot refuse lodgement but penalties and interest may be applied. As your registered tax agent, we engage the ATO proactively and make the case for penalty remission where applicable. The ATO generally responds better to agents than to individuals managing the process themselves.
7. What if I have missing records for past years?
This is common for overdue returns and is manageable. The ATO retains income data from employers, banks, and government agencies that can be used to reconstruct the key figures for past years. Our tax agents use ATO pre-fill data, bank records, and any documents you still have to prepare accurate returns even where original records are incomplete.
