If you had a spouse on 30 June 2018 or your spouse died during 2017–18 and you did not have another spouse before the end of the year, count all your dependent children.

If you were single or separated on 30 June 2018, count only the number of dependent children for whom you received the family tax benefit (FTB) during all or part of 2017–18. Count them even if you received only the rental assistance component of FTB Part A and you shared the care of the dependent child.
