Only two families out of 600,000 have opted to give up child benefit.
According to reports in the Irish Independent, two families returned their child benefit in 2012, in respect of one child each, meaning the State is now €3,360 better off.
Ryanair boss Michael O'Leary has been a critic of the allowance in the past , describing it as a "subsidy for people to have sex".
However, a spokesperson for the father-of-four declined to comment on whether he was one of the two parents who opted to give up the State benefit.
