HC Deb 19 January 1993 vol 217 c142W
Mr. Cousins

To ask the Chancellor of the Exchequer what is the Government's present policy with regard to the setting of pre-production expenses against tax liability as they are incurred; and what proposals he has to allow this in all areas of economic activity.

Mr. Dorrell

When calculating trading profits for tax purposes, revenue expenditure incurred in the five years before a trade commences is treated as if incurred when the trade starts, provided the expenditure would have qualified as a deduction had the trade commenced. Qualifying capital expenditure which is incurred for the purposes of a trade prior to its commencement is also deemed to have been incurred on the first day of trade.

These are general rules which apply to all trades.
