Everything you need to know about car allowance

Emmalena L. Ellis · 03 Aug

For many employees, having company car allowance is the stuff of dreams. That's probably why companies that offer them leave their competition by the wayside. But at what cost? Here's a guide to implementing a company car allowance policy.

Owning a company car can be seen as a reward for loyalty, provide an alternative to relocation for new employees or simply improve overall employee satisfaction and wellbeing.  

However, with fuel costs rising amidst concerns over the shift to hybrid and electric cars, the promise of a company car can come with growing costs and taxes. As such, many fleet drivers are choosing to take a cash alternative, reaching for a competitive personal contract purchase (PCP) deal instead. But what are the advantages and disadvantages of this? And how will salary sacrifice schemes impact overall employee remuneration? 

What's the difference between a company car and car allowance?

One obvious factor that compels employees today is the freedom of choice. The automobile industry is thriving with technological advancements at its helm. For an employee who uses their vehicle as an extension of their office, it's no longer simply a means of getting from point A to B. The increasing practicality provided by added mod cons such as sat nav, bluetooth, hands-free calling and parking sensors are paramount.  

By allowing employees to select a new car, with PCP there's a greater chance that they can select their vehicle at a competitive rate. PCPs also offer increased flexibility. Since the scheme only covers the depreciation of the vehicle over the duration of an agreement, rather than its full value, monthly payment plans can be brought down, which provide greater freedom based on their financial restraints. When the customer reaches the end of their agreement, they have can choose to either hand the keys back, buy the vehicle or begin a new PCP.

Reassurance and insurance 


When a company has its own maintained, insured and serviced fleet, the drivers, of course, have more security. Employers in possession of a fleet of cars can provide their people a cheaper option, when taking into account tax savings and salary sacrifices schemes in comparison to straight-up monetary repayments, and any initial upfront costs.

If a cash alternative is made readily available to employees, new HMRC tax regulation will likely be triggered, meaning employees will be taxed on higher Benefits in Kind (BiK) or the cash allowance. Alongside the employee’s higher tax liability, those offered cash allowances will lose the incentive to choose low emitting vehicles, since the tax benefit will be eroded.

Additionally, the employer will also be subjected to higher National Insurance contributions on any vehicles that were previously valued as a low BiK, making the process more complex and convoluted for new and existing employees based on their differing demands and needs.

Personalisation vs. unification

Another factor is branding. Part of the attraction to corporate car fleets is the uniformity with which they portray the company. Decisions relating to image and the operating cost play a huge part in the selection process. This often restricts certain makes, models and body types, such as convertibles or, for environmental reasons, certain emission brackets and fuel types.

However, cash allowances depend on the employee directly sourcing their vehicle from a dealership or website, which can be time-consuming. To avoid running into such complications, management should be mindful of this when considering the option to offer a cash allowance – especially in smaller teams. As the rates of BiK tax change every tax year, employers must remain savvy or risk forking out reimbursement costs to their employees.

The basics of BiK and car allowance tax

Every year the question of how much tax an employee will have to pay towards their annual BiK tax is calculated using three key factors. These are driver earnings, the cost of the car and the amount of CO2 it emits. Here's how it works: a person earning a lot of money in possession of an expensive car that emits high levels of CO2 will, quite rightly, pay through the nose in BiK tax. Reverse those three factors and they'll pay less.

With a unified fleet of pre-chosen cars, on the other hand, a company can easily figure out overall fuel costs and required millages and dedicate resources accordingly. This cuts out the trouble of having to adjust an employee’s salary to meet their automobiling tastes and habits.

However, with the growing focus on electric cars and surcharge of 4% on diesel cars, there's much debate about how the Vehicle Excise Duty (VED) will be affected. This is a basic amount payable on all cars, based on their CO2 emissions, regardless of whether they're for personal or business use.

Added to this, employers can find themselves caught up in the debate over whether or not to shift to an electric run fleet in the interim, and forking out for additional costs.

Hands-on or hands-off?

Cash allowances for company cars are typically added onto the employee’s monthly salary, which means it's subject to normal income tax. Employees will therefore need to calculate how this affects their take-home as tax bands come into play. 

In the case of company-provided cars, the administration and and maintenance are cared for by the business, leaving less choice for an employee but also less hassle. In contrast, cash allowances’ administration and maintenance costs are passed onto the driver. Thus allowing for further freedom in choosing a motor but also less guidance towards the overall upkeep.

Such decisions should not be taken lightly. This guide explains the considerations you should take when researching the best decisions for you.





Company car


Cash allowance


Financial Control


  • Employees pay Benefit In Kind  (BiK) on the company vehicle based on the value of the vehicle, CO2 emission level and tax rate.
  • You know what the monthly costs will be and so can budget accordingly.
  • Employees are free to spend the cash allowance in any way – not necessarily on a vehicle if they find that public transport may be more helpful in the role.
  • Employees do not pay BIK on the company vehicle, but the gross cash allowance is subject to yearly tax reviews and N.I deduction.
  • Employees need to take into consideration their financial circumstances e.g. cash allowance value, mileage and tax rates. Some drivers win and some lose
  • Drivers are responsible for the purchase, finance and running costs.

The Owner of the Car


  • The vehicle is chosen from an approved list and is owned by the company, not the employee.
  • Should the employee leave the company they will have to return the car.
  • The acquisition and disposal are the responsibility of the company.
  • Employees may own the car or be responsible for paying a finance agreement towards it.
  • If employment is terminated, former employees are responsible for buying and selling the car.

Insurance Policies


  • Insurance is paid for and dealt with by the company.
  • Accidents and other claims managed by the company, including the provision of an alternative vehicle.
  • Employees are responsible for Insurance cover that includes business travel (if employees are planning on using the car for business).
  • Insurance is a significant factor in vehicle choice, as individual circumstances will influence the cost considerably due to annual mileage, age, driving record and employee’s home location.
  • All accidents and claims need to be dealt with by the owner.
  • Owners incur replacement vehicle costs.


Maintenance Responsibilities


  • Peace of mind – Maintenance, MOT, breakdown, tyre, glass and road taxes are both paid for and dealt with by the company or its fleet management service provider.
  • Service benefits such as online booking, collection and delivery, wash and vacuum, courtesy vehicle provided.


  • Employees are liable for all maintenance costs, and unpredictable costs associated with this. Service levels and costs in garages are not monitored by the company and are at the employee’s own risk.
  • Employees need to arrange for maintenance and MOT work to be undertaken.
  • Once in ownership of a car, employees need to purchase breakdown cover.
  • Direct ownership may incur replacement vehicle costs and inconvenience.

Fuel and Reimbursement Policy


  • All costs, apart from private fuel, stay with the company.
  • Business mileage needs to be logged and claimed for, receipts need to be kept
  • If using a fuel card employees need to keep mileage records in order to split private and business fuel usage.
  • The company may pay all fuel consumption including drivers’ private mileage.
  • Reimbursements will need to cover depreciation, maintenance, tax and insurance costs in addition to fuel
  • Some companies may choose to cover fuel on an actual cost basis via fuel cards.
  • If companies are paying an employee a higher or lower reimbursement, rate than the AMAP’S rate, they may be entitled to tax relief or may incur a tax liability. Employees may have to wait until the end of the tax year to reconcile your tax position and regain any lost earnings.

Duty of Care


  • Under their fleet policy the company will ensure good risk management practices are in place to protect and improve driving for all drivers.


  • There is less focus on maintenance and roadworthiness of vehicle from a company perspective.
  • By extension, there is less risk management to ensure employees exercise safer driving practices.


The Environment

  • Some companies may offer incentives for cleaner vehicle choice.
  • They may provide access to alternative fuel vehicles such as hybrid models.
  • It may be easier to run and carry no residual value risk to the employee.
  • Employees may opt against a vehicle and use the cash to fund other travel methods e.g. season tickets for public transport.
  • Employees are free to choose any vehicle and so may not consider environmental performance a key criterion in this choice.
  • However environmental performance may be compromised due to cost and other practical considerations.



Choice of Vehicle

  • Employees are guaranteed a brand new vehicle in line with replacement policy e.g. every three years.
  • Choice is restricted to vehicles on the company car list – this may be open for employees to choose from.
  • Discounts are included and may enable a better vehicle and/or spec to be selected.
  • Trade up/down enables further flexibility if offered
  • Extras policy may limit the options that can be selected.
  • Theoretically employees have a free choice of any vehicle and any optional extras.
  • There is also the flexibility to change the vehicle at any time (but this will have an implication on costs.)


Steering your thoughts


There's no single right way to approach car allowance. It's ultimately a question of whether a company wants to put the responsibility into their employee’s hands. It's in turn up to an employee to consider whether accepting the cash and freedoms that surrounds owning their car is worth the costs in upkeep and salary sacrifice.

Regardless of the approach you decide to take, always research your options carefully.
