Why You Should Avoid Private Mileage Deductions

Businesses generally use ‘private mileage deduction’ schemes to avoid having employees pay benefit in kind tax when using company cars for their private journeys. Below, we will see why these schemes are far from ideal and what alternatives you should take into account to manage mileage expenses.

Those who drive for work are often provided with a company vehicle that they can also use for private journeys. However, unless the employee pays for the fuel themselves, HMRC considers their private mileage to be a taxable benefit in kind.

Because of this, many employers have set up private mileage deduction schemes to avoid having employees pay benefit in kind tax. These generally work as follows:

  1. John, the employee, uses a company car for private trips
  2. John pays for the fuel expenses using his employer’s company fuel card
  3. John’s employer deducts fuel expenses from his salary

Here is an example of how to calculate the private mileage deduction amount using HMRC’s Advisory Fuel Rates:

Private mileage deductions – a case study

John drives a company car with a 1400cc petrol engine. It’s 1st May and he has used his company car to drive 300 miles for private trips during April.

John’s employer multiplies the AFR rate with the number of miles he drove to calculate his private mileage deduction which came to £36.

300 miles x £0.12 = £36

If John’s monthly gross salary is £3000, his salary in May will be £2964 (£3000 – £36).

Please bear in mind that his £3000 salary is still fully taxable for PAYE and National Insurance purposes.

It sounds simple enough. So what’s the problem?

This may seem simple and fair, but, in practice, it isn’t so straightforward. Employers usually have to trust that their employees have accurately declared their private mileage, with no way of checking if the numbers are correct.

In addition, employees may inevitably forget to record every private trip they make, especially as it’s time-consuming and invasive to manually record and share information about every journey.

For example, let’s say that John was in a rush when he filled out his mileage claim so he only declared 150 of the personal miles he drove in April, forgetting 150 miles. Because of his mistake, his salary deduction would have totalled £18 rather than £36.

This can cost your business a considerable amount of money over time, especially if many of your employees drive for work. In fact, 90% of company car drivers have admitted to having submitted inaccurate mileage claims, which has cost companies millions.

Moreover, HMRC can decide to inspect your business and penalize you for any inaccuracies. These penalties can go as high as 6 digits if HMRC finds that your business mileage records are not kept adequately.

How can I avoid private mileage deductions?

Many employers have moved away from these type of schemes and opted instead for business mileage deduction schemes, effectively reversing private mileage deductions.

This means that rather than employers paying for fuel via fuel cards or the like, employees pay for all of their fuel, both business and private. Employers then reimburse the amount spent on fuel for business trips in the form of a business mileage claim, as we can see in this example.

In the past, this was never a feasible way to calculate the private use of company vehicles but, with emerging technology that automates the mileage claim process, it has fast become the method of choice.

Business mileage claims can benefit you and your employees in a number of ways, for example:

  • By improving the accuracy of mileage claims
  • By removing the cost associated with fuel cards
  • By ensuring HMRC compliance
  • By improving transparency across the entire company

Additionally, drivers enjoy more privacy as they no longer have to record all their private trips. As the process is automated, they also save time logging mileage which they can redirect on more important tasks.
