§ Dr. Lynne Jones
To ask the Secretary of State for Social Security what has been the total revenue raised from national insurance in each of the last three years for which figures are available; and what the figures would be if the rate had remained unchanged since April 1992. 
§ Mr. Heald
The information requested is in the table.
Total class 1 contribution revenue for employers and employees (£ billion) 1993–94 1994–95 1995–96 Actual revenue1 38.70 41.55 43.10 April 1992 rates2 37.65 39.50 41.20 1 Figures show the amount due for each tax year and will differ slightly from the amount actually paid by employers and employees during the tax year due to the normal delays inherent in the collection system. 2 Assumes that the contribution rates and level of contracted-out rebates in force in April 1992 remained in force from 1993–94 to 1995–96, but the lower and upper earnings limits and earnings bands for those years still apply.
Estimates of rates other class 1 have not been provided as the effect will be negligible.
