How Much Child Support Will I Pay if I Earn $120k in Australia?
Direct answer: If you earn $120k in Australia, a simple 2026 one-child example with the other parent on $60k ranges from $13,485 per year in a low-care payer scenario to $4,547 per year in an equal-care scenario. That is not a formal assessment; your exact result depends on both parents' inputs.
Assumptions for these examples
- Australia, 2026 Australian child support formula.
- $120k is treated as adjusted taxable income, not take-home pay.
- One child under 13, no relevant dependent children, no multi-case children, and no non-parent carer.
- The other parent is assumed to have $60k adjusted taxable income.
- The 2026 self-support amount used by the calculator is $31,046.
- These are calculator-derived examples, not Services Australia assessments.

At this income, the higher child support income creates a larger income percentage gap, but shared care can still reduce or reverse the amount. The table keeps income and child assumptions fixed, then changes care percentage so you can see why the same salary can produce different outcomes.
| Care scenario | Care assumption | Annual estimate | Monthly | Weekly | Direction |
|---|---|---|---|---|---|
| Low or no care | 0 nights per year for you; 365 nights for the other parent. | $13,485 | $1,124 | $259 | Under these assumptions, you would pay the other parent. |
| Regular care | 52 nights per year for you; 313 nights for the other parent. | $9,195 | $766 | $177 | Under these assumptions, you would pay the other parent. |
| Shared or equal care | 50% care for each parent. | $4,547 | $379 | $87 | Under these assumptions, you would pay the other parent. |
Low or no care
You have 0 nights and the other parent has primary care. With $120k adjusted taxable income and the other parent on $60k, this scenario estimates $13,485 per year.
Under these assumptions, you would pay the other parent. The result changes because the formula compares your income percentage with the cost percentage created by care.
Regular care
You have regular care at about one night per week. With $120k adjusted taxable income and the other parent on $60k, this scenario estimates $9,195 per year.
Under these assumptions, you would pay the other parent. The result changes because the formula compares your income percentage with the cost percentage created by care.
Shared or equal care
Both parents have equal care. With $120k adjusted taxable income and the other parent on $60k, this scenario estimates $4,547 per year.
Under these assumptions, you would pay the other parent. The result changes because the formula compares your income percentage with the cost percentage created by care.
Why the Result Changes
Child support is not a fixed percentage of $120k. The formula first deducts the self-support amount from each parent's adjusted taxable income, then compares each parent's share of the combined child support income with the share of costs they are treated as meeting through care.
- Other parent income: a lower other-parent income usually increases your income percentage; a higher other-parent income can reduce it or change who pays.
- Child age and count: the cost of children table changes by age band and number of children.
- Care percentage: moving from low care to regular care or shared care changes your cost percentage. Use the care percentage calculator to convert nights to percentages.
- Income estimates: if current income differs from the income year Services Australia is using, an estimate can change the assessment. Start with How Income Works.
How to Get a More Accurate Estimate
- Confirm both parents' adjusted taxable incomes, not just gross salary or take-home pay.
- Work out the annual care nights or percentages for each child.
- Check whether any relevant dependent children, other child support cases, non-parent carers or income estimates apply.
- Run those inputs through the child support calculator.

Frequently Asked Questions
How much child support will I pay if I earn $120k in Australia?
There is no flat amount for a $120k income. In the 2026 example on this page, the result changes with care percentage even though the income inputs stay fixed. Use the calculator for your exact child age, child count, income and care details.
Is $120k income gross income or adjusted taxable income for child support?
This page treats $120k as adjusted taxable income. Child support does not simply use take-home pay. Services Australia starts from taxable income and applies child support adjustments, including certain add-backs and deductions.
What other parent income is used in the $120k examples?
The worked examples assume the other parent has $60k adjusted taxable income, one child under 13, no relevant dependent children, no multi-case children, and no non-parent carer. Different other-parent income can materially change the result.
Can $120k produce no child support payable?
Yes. A $120k income can produce no transfer amount where the income percentages and care-based cost percentages are closely matched, or where the other parent is the formula payer. The result depends on the full formula, not income alone.
