How is Australian Child Support calculated in 2026?

It is calculated using the official 8-step formula based on combined income, care percentages, and cost of living tables provided by Services Australia.

Does 50/50 care mean no child support?

Not necessarily. If there is a significant income disparity between parents, child support may still be payable even with 50/50 shared care.

What are special circumstances in child support?

Special circumstances are situations that are too complex for the standard child support calculator. These include issues with income reporting, property settlements, high child care costs, or upcoming court hearings that may affect your assessment.

Can I select multiple special circumstances?

Yes, you can select multiple circumstances that apply to your situation. The system will identify the highest priority circumstance to help match you with appropriate legal assistance.

What happens after I select my circumstances?

After selecting your circumstances, you will be directed to speak with a family lawyer who can help you request adjustments to your child support assessment through Services Australia.
