Child support and Family Tax Benefit

Receiving child support can reduce your Family Tax Benefit Part A. This surprises a lot of payees, who reasonably assume the two payments are unrelated. They aren't — and the interaction means every extra dollar of child support above a threshold is worth less than a dollar in your pocket.

The maintenance action test

To receive more than the base rate of FTB Part A, a parent must take reasonable steps to obtain child support from the other parent. In practice that means applying for an assessment. If you don't, your FTB Part A can be reduced to the base rate even though you're receiving nothing from the other parent.

Exemptions exist where pursuing child support would put you or the children at risk — family violence being the most common ground — or where the other parent cannot be identified or located. Exemptions are granted by Services Australia and are reviewed periodically.

The maintenance income test

Child support you receive is counted as maintenance income. There's a maintenance income free area — an annual amount you can receive before it affects anything, indexed each July and higher if you have more than one child or a partner who also receives maintenance. Above that free area, FTB Part A reduces by 50 cents for every dollar of child support received, until it reaches the base rate.

The practical effect: in that band, an extra $100 a month of child support increases your total income by $50, not $100. It's not a reason to avoid child support — you're still better off — but it explains why an increased assessment often feels smaller than expected.

Entitlement vs actual receipt

This is the part that catches people out. For families where Services Australia collects the child support, FTB is generally worked out on the amount you were entitled to receive, not what actually arrived. If the other parent doesn't pay, your FTB can still be reduced as though they had.

There is relief for this. Where child support goes unpaid, you can ask Services Australia to reassess your FTB based on what you actually received — but it isn't automatic, and it's worth raising as soon as arrears start accumulating rather than waiting for the end-of-year reconciliation.

Private collect and the disbursement rule

If you have a private collect arrangement, FTB is generally based on the full assessed amount on the assumption it's being paid. If payments stop, switching to Child Support Collect is usually the first step — it both starts enforcement and gives Services Australia a record of what was actually received.
