Child benefit payments could be cut to around €100 per child each month, according to a report compiled by an advisory group to the Social Protection Minister.
The report seen by RTÉ's The Week in Politics recommends what it calls a two-tier child benefit system.
It would see a cut to the universal payment with top-up payments then made available to low income families.
The report says this proposal could save up to €200m a year.
Currently, child benefit is paid at €140 per child for the first two children, the third child receives €148, while €160 is paid for the fourth and subsequent children.
In last year's Budget, Public Expenditure and Reform Minister Brendan Howlin said the rates would be standardised to €140 for all children over the next two years.
