Section 26 sets out the expiry dates for a number of tax incentive schemes. Those affected are the urban renewal scheme, the town renewal scheme, the park and ride scheme and the student accommodation scheme. Sections 27 to 30 make various minor changes to these schemes. I have always held the view that targeted, well designed tax incentive schemes can be a useful instrument in achieving desirable public policy objectives. As I said earlier, these are very different from unintended uses of the tax system through tax loopholes and avoidance schemes. However the value of such incentive schemes must be balanced against the important objective of ensuring a wide tax base if we are to maintain low rates. It must be borne in mind that such schemes usually also mean that higher earners can reduce their tax bill substantially.
