Family Tax Benefit (FTB) is an Australian Government payment to help families with the cost of raising children. It is paid in two parts — Part A (based on family income and number of children) and Part B (based on family structure and the lower earner's income). Both parts interact directly with Child Care Subsidy because they are assessed against the same Adjusted Taxable Income figure.
FTB Part A is paid per child. The maximum fortnightly rate for a child under 13 is $222.04. Families with income up to $62,634 receive the maximum rate. The rate reduces by 20 cents for every dollar above that threshold. Above $107,892 the payment reduces further and phases out entirely as income rises. The standard rate for older children (13–17) is lower, and a supplement of up to $916.15 per child may be paid after end-of-year tax balancing.
FTB Part B is paid per family and targets single-income households or families where one parent earns significantly less. The primary earner income limit is $117,194 — above that, Part B is not available. For the secondary earner, the payment reduces by 20 cents for every dollar earned above $6,059. Maximum fortnightly rate is $193.34 (youngest child under 5) or $134.96 (youngest 5–13). FTB Part B is not payable when the youngest child turns 13 (or 18 for children with a disability).
Both FTB and CCS are assessed using the same Adjusted Taxable Income (ATI) figure. If your income changes during the year — from a bonus, salary rise, salary packaging arrangement, or novated lease — both payments may be affected simultaneously. Modelling FTB alongside CCS helps you avoid surprises at end-of-year balancing when Services Australia reconciles payments against your actual tax return income.
FTB is paid throughout the year based on an income estimate. After you lodge your tax return, Services Australia reconciles the estimate against your actual ATI. If your income was higher, you may owe a debt. If lower, you receive a top-up. Lodging your tax return promptly reduces delays and releases any withheld supplement amounts.
If you share care of a child with another parent, FTB is apportioned based on the percentage of care you provide. You need at least 35% care to be eligible. If you receive child support (maintenance income), amounts above the maintenance income free area reduce FTB Part A. The calculator supports both shared-care arrangements and maintenance income inputs.
Estimate your FTB Part A and Part B entitlements. Family Tax Benefit is income-tested and directly interacts with Child Care Subsidy — model both together to understand your full family support picture and avoid end-of-year balancing debts.
