Yes you are, as long as you meet the criteria attached to the payment, which is known as the Family Income Supplement (FIS). It is a weekly tax-free payment available to employees with children. It gives extra financial support to people on low pay. You cannot qualify for FIS if you are only self-employed - you must be an employee to qualify.
You must have at least one child who normally lives with you or is financially supported by you. Your child must be under 18 years of age or between 18 and 22 years of age and in full-time education. To qualify for FIS, your average weekly family income must be below a certain amount for your family size. The FIS you receive is 60% of the difference between your average weekly family income and the income limit which applies to your family.
