Life happens—sometimes, you may find that your Centrelink tax return doesn’t quite reflect your true financial situation for the year. In Australia, amending your tax return is common and nothing to stress over. This guide will help you understand the reasons for amendments, simplified steps to make changes, and everything you need to know about services and schemes that may be affected.
Common Reasons for Amending Your Tax Return
Mistakes in your tax return can happen for all sorts of reasons. The most common include:
Forgetting to report income—such as bank interest, Centrelink payments or other income streams
Missing a deduction or claiming a deduction you weren’t eligible for
Updates to your Centrelink payment summary after you’ve already lodged
Changes in your circumstances, like receiving an extra payment or having a debt repaid
Information that was incorrect or incomplete when you lodged
You might also need to amend if your Centrelink payment summary changes after the end of the financial year. If this is the case, you’ll get a letter or notification from Services Australia.
How Amending Your Tax Return Works
When to Lodge an Amendment
Amendments can be made any time you realise there’s a mistake. However, it’s always best to wait until you receive your original notice of assessment. This ensures all records are up to date before you submit an amendment.
How to Amend
You have several ways to update your tax return if you need to make a change:
Online Via myGov:
Sign in, link the ATO, and choose “Manage tax returns” then “Amend” next to the relevant financial year. Online amendments take around 20 days to process.Paper Amendment Form:
Download, complete, and mail the amendment form. Processing can take up to 50 business days.Through Your Tax Agent:
Your registered agent may lodge amendments electronically or by mail on your behalf.By Letter:
Write to the ATO with your details, explain the amendment and send any supporting documents. Include your TFN, the year, updated details, why you’re amending, and a signed declaration.
Deadlines
Most individuals can amend their returns for up to two years after the assessment date. For more complex cases or businesses, exceptions may apply.
What Happens Next
After you lodge an amendment, the ATO reviews your request. If you’re owed a refund, you’ll receive it. If you owe additional tax or have a debt, you’ll be notified how to make payment.
Impact on Services Australia Payments and Schemes
Some government payments and support services depend on your reported income. Amending your tax return may affect:
Family Tax Benefit and Child Care Subsidy: These are recalculated based on your actual income once your tax return is finalised.
Child Support: Income changes can alter either parent’s child support payments or obligations.
Centrelink Debts: Overpayments can be recovered, often using your tax refund if a debt exists.
Scheme Information Table
| Scheme Name | What Changes After Amendment |
|---|---|
| Family Tax Benefit/Child Care Subsidy | Payment is rebalanced based on actual amended income. You’ll receive an updated outcome. |
| Child Support | Your amended income can alter the assessed child support payment obligations. |
Mistakes to Avoid When Lodging and Amending
Lodging too early: Wait for all income to pre-fill and Centrelink summaries to update, especially if you receive government payments.
Not checking details: Missing or incorrect data can create family payment debts or underpayments.
Delaying amendments: Endeavour to act promptly if you know there’s a mistake, which could help reduce any penalties.
Getting Notified of Changes
If a change happens after you lodge (for example, Centrelink reports new information), Services Australia will notify you. If your support payment outcome changes, expect a letter to arrive outlining what’s different and any follow-up you might need.
Simple Steps for Amending Your Tax Return
Wait until the ATO processes your original return.
Check your income, deductions, and Centrelink summaries for the year.
Choose your preferred amendment method: online, via agent, or by mail.
Submit the corrected details and any documentation.
Stay informed through myGov notifications or post.
Review any updated assessments for refunds or debts.
How Amending Can Affect Your Refund or Debt
If you’re owed more money, your refund is processed after your amendment.
If you owe tax or have a debt (to the ATO or Centrelink), payment instructions are sent outlining how to settle it. Services Australia can use your refund to recover any Centrelink debt.
