Cars, fuel and mileage

There are two ways to claim for the costs of your car, motorbike or bicycle:

  • By claiming mileage at a fixed rate
  • By claiming the business share of your vehicle (which could include lease/hire costs, fuel and maintenance). If you rent a vehicle for exclusively business purposes eg if travelling for work, then that would be claimable along with the associated fuel.

You should only claim the vehicle costs in one way so you don't double claim. In all cases, you should be in a position to justify what you are deducting.

Claiming mileage is the quickest and simplest way to allocate expenses relating to the use of your personal car, motorbike or bicycle for business purposes. untied automatically works out the correct rate.

If you claim the business share of the costs of the vehicle you may want to see the related article on splitting transactions.
