FTB Part B Explained: Eligibility, Rates & Income Test (2025-26)

FTB Part B is often misunderstood. Unlike Part A (which is per child), Part B is a per-family payment that provides extra help for single parents and families with one main income earner. The amount depends on your youngest child's age and your family income structure—not the number of children you have.

What is FTB Part B?

Family Tax Benefit Part B recognizes that single-parent families and families with one main income earner face different financial pressures than dual-income families. It provides extra financial support on top of FTB Part A.

Eligibility for FTB Part B depends on whether you're a single parent or couple, and your income levels.

FTB Part B Eligibility Rules

FTB Part B has two rate levels (maximum and base) depending on your income. The amount also depends on your youngest child's age.

The income test for FTB Part B is different from Part A. It focuses on the primary earner's income limit and the secondary earner's income test.
