Yes, you can amend a tax return after it has been lodged in Australia. Common reasons to amend: a deduction you forgot to claim, an income figure entered incorrectly, or a relevant offset you missed.
Can you amend a lodged tax return?
Yes. Australian tax law allows you to request an amendment after a return has been assessed:
- Correct errors
- Add missing income
- Claim deductions you forgot
- Apply offsets you missed (LITO, small business, Medicare Levy exemption)
- Update figures that were entered incorrectly
The amendment process is formal and must be lodged in writing (cannot be done by phone).
How long do you have to amend?
The standard time limits:
- Individuals and small businesses: 2 years from the date of original assessment
- Other taxpayers: 4 years
- Fraud or evasion cases: no time limit (ATO can amend any time)
For working holiday makers, the 2-year window means you have until two years after lodgment to make corrections. After that, amendments require special application and are harder to get approved.
How do you lodge an amendment?
The process through our team:
- Get in touch with the issue identified
- Send us the original return and the correction needed
- We prepare the amendment with supporting documentation
- We lodge the amendment on your behalf
- The ATO processes (usually a few weeks to a couple of months)
- Any additional refund is paid to your nominated account
If you originally lodged through our team, we have your records and the amendment is straightforward. If you lodged elsewhere, we can still handle the amendment but need a copy of your original return.
What happens to your refund during an amendment?
The outcome depends on whether the amendment increases or decreases the refund:
If the amendment increases your refund:
- The additional amount is paid to your bank account
- Processing takes a few weeks to a couple of months
- You receive the original refund plus the additional amount
If the amendment reduces your refund:
- The ATO issues a revised assessment
- You owe the difference back
- Usually due within 21 days of the revised assessment
- We can arrange a payment plan if needed
Can the ATO amend your return?
Yes. The ATO can also initiate amendments:
- Time limit: 2 years for standard cases
- No time limit for fraud or evasion
- Notifies you of the amendment via assessment notice
If the ATO amends your return and you disagree, you can lodge an objection through the formal appeal process. See our article on appealing ATO decisions.
What if you have already left Australia?
Amendments can be lodged from anywhere in the world:
- Our team manages the process remotely
- Your Australian bank account receives any additional refund
- The 2-year window still applies regardless of where you are
If you closed your Australian bank account, send us your overseas account details and we will arrange alternative payment.
Common amendments we lodge for working holiday makers
Frequently corrected items:
- Medicare Levy exemption not claimed
- Work-related deductions overlooked (uniforms, tools, training courses)
- ABN income misreported or missed
- Tax withheld figures incorrect (employer reporting errors)
- Foreign income that should have been excluded
- Wrong residency status applied
Most amendments result in a larger refund. Self-lodgers miss eligible deductions and offsets that we routinely catch. If you lodged yourself and want a second opinion, send us your previous return and we will review it for free.
