    End of attention

    Australian resident

    Generally, the Tax Office considers you to be an Australian resident if:

    • you have always lived in Australia or you have come to Australia and live here, or
    • you have actually been in Australia for more than half of the income year - unless your usual home is overseas and you do not intend to live in Australia.

    Base year

    A base year is the year which acts as a basis to compare taxable income in your claim year. This base year stays the same for all future claim years for the baby bonus for an eligible child. Once a base year is chosen, it cannot be changed or revoked.

    If you have claimed the baby bonus before for your child, your base year is shown on the notice you received from the Tax Office.

    For an eligible person their base year will be the year before legal responsibility for the eligible child started, unless they choose the year that legal responsibility started. See How does the baby bonus work? for more information.

    For a transferee if this is the first year they will claim the baby bonus for the eligible child their base year is 2002.

    For an eligible person who was not an Australian resident in the year immediately prior to gaining legal responsibility of the eligible child, their base year is the year they gained legal responsibility of the child.


    For a child to be in your care, it is not a requirement for the child to be living with you on a daily basis. For example, parents who place their child in a cr che or home based day-care would still be considered to have care of the child. This is because the parents are ultimately responsible for making decisions in relation to that child and will continue to make those decisions.

    Where parents share the legal responsibility for and care of a child (for example, where a child spends alternate weeks with their separated parents), the child is considered to be in the care of both parents at all times. Where there is 'shared care', usually the mother will be the eligible person (see the Selection list).

    A parent who has ceased to be involved in the child's daily life and has ceased to provide for the day-to-day care, welfare and development of the child would not be considered to have care of that child.

    Claim period

    A claim period is the period within the claim year for which you are eligible to claim the baby bonus.

    Claim year

    A claim year is the year in which you make a claim. You may make a claim each year until your eligible child turns five.

    Eligible child

    The eligible child is the child for whom you first satisfy step 2 under Are you the eligible person for the baby bonus? It is usually the first child you gave birth to or the first child you gained legal responsibility and care of, after 30 June 2001. It is not necessarily your oldest or first-born child.

    A stillborn child cannot be an eligible child.

    Legal responsibility

    You have legal responsibility for a child if you are responsible (whether alone or with someone else) for the day-to-day care, welfare and development of the child and:

    • you are their birth parent or
    • you have a court order stating that you are legally responsible for the child (for example, you are their adoptive parent).


    Your spouse is your husband or wife - either married or de facto.

    Taxable income

    Your taxable income can be found on your notice of assessment from the Tax Office or on your tax return.

    Taxable income is your assessable income - for example, salary or wages, most Centrelink payments, interest, dividends - less any allowable deductions that you have incurred in earning that income.

    Centrelink payments such as maternity allowance and family tax benefit are not assessable income.

    If you are unsure of how to calculate your taxable income, you can get more information:

    • on the Tax Office website at
    • in TaxPack 2003, or
    • by phoning the Personal Tax Infoline on 13 28 61, press 2 to be directed to the appropriate area.


    A transferee is the spouse of an eligible person, and they have had the eligibility for the baby bonus transferred to them.
