HC Deb 17 February 1984 vol 54 c346W
Mr. Ralph Howell

asked the Chancellor of the Exchequer what is his estimate of the number of families entitled to family income supplement who also have to pay income tax; and what is the total value of revenue earned from this source.

Mr. Moore

I regret that the information is not available. It is not possible to identify families eligible for family income supplement from data held on tax records nor to make satisfactory estimates of the information requested from data available from other sources.
