Family Tax Benefit Part A
Family Tax Benefit Part B
What is this tool?
Family Tax Benefit (FTB) has two parts. Part A is paid per child and reduces as family income rises (it is the higher of a maximum-rate test and a base-rate test). Part B is an extra payment for families with a lower-income second earner. This tool estimates the 2025-26 fortnightly rates using the standard scales.How it works

Frequently Asked Questions
How is Part A worked out?
Part A is paid per child at the maximum rate, then reduced on a higher income test (50c per $1 over the threshold). If that reduces it to nothing, a base rate (paid on a separate threshold) may still apply. The tool shows the higher of the two.
Who gets Part B?
Part B goes to families with a lower-income second earner (or a single parent). It cuts out once the primary earner income passes the limit, and tapers as the second earner earns more.
What is not included?
This is a simplified estimate. It excludes the FTB Part A supplement, energy supplements, the large-family supplement, and the full interaction with other payments. Services Australia makes the formal assessment.

Limitations
Uses the 2025-26 FTB Part A and Part B rates and income tests, assuming a direct-payment claim for the full year with no maintenance income and no shared care. It does not model the FTB supplements, grandparent or carer allowances, or the choice between fortnightly payments and a lump sum. Services Australia calculates your actual entitlement.
