Planned system outage - 12 September 2026 | Our online services including myIR, self service phone lines and gateway services will be unavailable on Saturday 12 September, 2026 from 1pm to approximately 10.30pm while we complete a planned system update. We apologise for any inconvenience this may cause.

We need to know about the changing income of our Working for Families and child support customers. Keeping us up to date makes sure you get and pay the right amounts and it keeps you out of debt. We need to know because:

  • Working for Families is income tested, the amount we pay you depends on your income
  • child support based on a formula assessment uses the income details of both people.

If you're paying child support and your income has changed, find out more about estimating your income for child support.
