Child Support Change of Assessment Reason 8
Reason 8 is the Change of Assessment ground used when the standard child support formula does not properly reflect a parent's income, earning capacity, property or financial resources. It is the ground parents usually look at for underemployment, hidden income, business structures, assets, trusts or lifestyle evidence.
Reason 8 in Plain English
The child support formula starts with adjusted taxable income. Reason 8 exists because taxable income is sometimes an incomplete picture. A parent may be capable of earning more, may control business income, may hold assets that reduce their living costs, or may have access to resources that are not obvious from a tax return.
Common Reason 8 Scenarios
- A parent leaves a higher-paid job or reduces hours after separation.
- A self-employed parent declares low taxable income while the business funds personal costs.
- A company director takes a low wage while retaining profits in a company.
- A parent appears to work for cash or under-report income.
- A parent owns property, shares, trust interests or other resources not reflected in taxable income.
- A parent has qualifications and work history that suggest a higher earning capacity than current income.
Evidence Checklist
| Issue | Evidence to consider |
|---|---|
| Earning capacity | Prior tax returns, qualifications, work history, job ads, salary benchmarks. |
| Business income | Business tax returns, profit and loss statements, BAS, financial statements, director drawings. |
| Property or assets | Property searches, rental statements, mortgage information, ASIC searches, trust records. |
| Lifestyle mismatch | Bank records, vehicle records, travel evidence, school fee records, visible spending patterns. |
| Cash or hidden income | Invoices, messages, business records, industry benchmarks, evidence of regular work. |
What Services Australia Usually Tests
- Is the current assessment based on an incomplete or misleading financial picture?
- Is there documentary evidence, not just suspicion?
- Is the parent lower income explained by health, caring responsibilities, job loss or genuine business conditions?
- Would a departure be just and equitable for both parents and the child?
- What figure should replace or adjust the income used in the formula?
Reason 8 Is Not a Shortcut
A Reason 8 application is strongest when the evidence is specific. A claim that the other parent "must be earning more" is weak by itself. A file with prior income, current qualifications, available jobs, business documents and spending evidence is much stronger.
