HC Deb 19 May 1942 vol 380 c51W
Mr. Keeling

asked the Chancellor of the Exchequer what is the estimated cost of assessing and collecting the National Defence Contribution?

Sir K. Wood

It is not possible to make a separate estimate of the cost of assessing and collecting the National Defence Contribution, as the work is merged in the general work of assessment and collection of the Income Tax and the Excess Profits Tax.
