HL Deb 30 June 1978 vol 394 c633WA

asked Her Majesty's Government:

Whether they will list the percentage of taxpayers who have a marginal tax rate at or above 60 per cent in Great Britain, Ireland, Holland, USA, Belgium, Italy, France and Japan.

Baroness BIRK

The information necessary to answer the question is not available from international sources. For the United Kingdom, approximately 1.2 per cent. of all taxpayers (counting married couples as one) have a marginal tax rate of 60 per cent, or more.
