Tax relief on company cars

New rules have been introduced for expenditure incurred on cars on or after 1 April 2009 for businesses in the charge to corporation tax and 6 April 2009 for businesses in the charge to income tax. From these dates, expenditure on cars will be allocated to one of the two general plant and machinery pools, depending on the cars' CO2 emissions. Expenditure on cars with CO2 emissions over 160g/km will be dealt with in the special rate pool and will attract WDAs at 10 per cent.

Cars that have an element of non-business use will continue to be dealt with in a single asset pool to enable the private use adjustment to be made, but for expenditure incurred from April 2009 onwards the rate of WDA will be determined by the cars CO2 emissions.

Expenditure incurred before April 2009 will, in general, continue to be subject to the old 'expensive' car rules for a transitional period of up to five years. After this transitional period, any expenditure remaining in a single asset pool will be transferred to the main capital allowances pool.

The lease rental rules will also be replaced for leases commencing on or after April 2009 with a flat rate disallowance of 15% for cars with CO2 emissions of 160g/km or more. This disallowance will only apply to one lease rather than all links in a chain of leases.

Our view
These new rules reflect the government's stated intention of encouraging use of more environmentally friendly modes of transport through fiscal means.
