Business Cars bought from April 2015

Company Cars bought April 2013 to April 2015

Company Cars bought April 2009 to April 2013

Note: If you bought cars before April 2009 you should move the balance to your main rate allowances pool. Use the 'special rate' if your car has no emissions figure. Use the main rate for cars registered before the 1st of March 2001.

Using Company Cars Outside of the Business

Sole traders or partners may also use their cars outside the business. You must work out the amount you can claim based on the amount of business use the car gets.

You can claim capital allowances on the full cost if the business provides a car for an employee or a director. But, you may need to report a car used 'personally' if it falls under the rules of expenses and benefits for employers.
