Using your own car for work purposes

Using your own car or bike for work travel? You may be able to claim tax relief for business mileage.

If you are employed and spend your own money on items needed for your job, you may be eligible to claim tax relief on those expenses. However, you can usually only claim tax relief on items that are exclusively used for work purposes.

For example, you might be able to claim tax relief when using your own vehicle, whether it is a car, van, motorcycle or bicycle, for work-related travel. Generally, travel between home and your regular place of work does not qualify. However, if you travel to a temporary workplace or incur business mileage, tax relief is typically allowed.

Employers often reimburse mileage using a set rate per mile depending on the type of vehicle. HMRC publishes approved mileage rates that apply when employees use their own vehicles for business journeys. If your employer uses these rates, the reimbursement is not treated as a taxable benefit.

If you are reimbursed at a rate below the HMRC approved amount, you can claim tax relief on the difference through Mileage Allowance Relief. For cars, the rate is 45p per mile for the first 10,000 miles and 25p per mile thereafter. The rate is 20p per mile for bicycles and 24p per mile for motorcycles.

Additionally, there is a passenger payment of 5p per mile per colleague if you transport other employees during business journeys in a car or van.
