Your checklist should include your children’s birth or identity details, Australian residency information, care arrangements and your estimated annual family income. You may also need bank details, relationship or partner information, and documents confirming your child’s schooling or immunisation where relevant. Check whether you are applying for Family Tax Benefit Part A, Part B, or both, and report changes in income, care or family circumstances promptly. Apply or update your claim through myGov linked to Centrelink, and check Services Australia for the current requirements and eligibility rules.
