HC Deb 20 January 1970 vol 794 cc91-2W
57. Mr. John Wells

asked the Chancellor of the Exchequer if he is aware of the growing tendency among building trade operatives to work only a proportion of the week with their normal employers and to seek other and private employment for which they can avoid paying taxes; and what action he is taking to stop this avoidance of tax payment.

Mr. Diamond

Casual earnings from spare-time work are taxable and it is a statutory offence to omit them from the income tax return. The Inland Revenue keeps a close watch on cases where opportunities for spare-time work arise.
