HC Deb 02 July 1974 vol 876 c144W
Mr. John Garrett

asked the Chancellor of the Exchequer what would be the cost to the Exchequer of doubling the child allowances for income tax purposes, but not altering the tax threshold for married couples without children.

Dr. Gilbert

The estimated cost in a full year of doubling the rates of child tax allowance proposed for 1974–75 is about £1,020 million.
