Car Benefits and Allowances

Claiming Benefits and Allowances for Company Vehicles

Car benefits and allowances help employers support employees who use a car for work but they can also create tax liabilities if not handled correctly. Company cars, car fuel benefits, and mileage allowances are all common ways to cover travel costs, but each is taxed differently and must be reported to HMRC.

This guide explains how car benefits and allowances work, who pays tax on them, and what you need to know to stay compliant and claim the right reliefs.

What Are Car Benefits and Allowances?

Car benefits and allowances are payments or perks employers give employees who use a car for work or business travel. These can include:

Company Cars:
A company-provided car that an employee can use for business and private journeys. The value of this benefit is taxable and worked out using HMRC’s benefit-in-kind (BIK) rules, based on the car’s list price and CO₂ emissions.

Car Fuel Benefit:
If an employer pays for fuel for private use in a company car, this creates an extra taxable benefit which must also be reported and taxed through payroll or a P11D.

Mileage Allowances:
If an employee uses their own car for work, employers can pay tax-free mileage allowances up to HMRC’s approved rates. Anything paid above these rates is taxable.

Car benefits and allowances help employees cover travel costs, but it’s important for employers and employees to know how they’re taxed and reported.

Getting Started with Car Benefits and Allowances

Before offering or claiming car benefits and allowances, it’s important to understand how they’re taxed and what records you need to keep.

Company Cars:
If you provide a company car, you must calculate the benefit-in-kind (BIK) value based on the car’s list price, CO₂ emissions, and any contributions made by the employee. The taxable benefit is reported to HMRC, usually through payroll or a P11D form.

Car Fuel Benefit:
If you pay for or reimburse fuel for private journeys, this creates a separate taxable benefit. Many employers choose not to cover private fuel because the extra tax can outweigh the benefit.

Mileage Allowances:
If an employee uses their own car for work, employers can pay tax-free mileage allowances up to HMRC’s approved rates (45p per mile for the first 10,000 miles, then 25p). Payments above these rates are taxable and must be reported.

Understanding the basics helps employers provide the right support for travel costs while keeping tax bills accurate and avoiding penalties.

Quick Menu:

Car Benefit

The car benefit is calculated by multiplying the car's list price, when new, by a percentage linked to the car's CO2 emissions.

For diesel cars generally add a 4% supplement (unless the car is registered on or after 1 September 2017 and meets the Euro 6d emissions standard).

The overall maximum percentage is capped at 37%.

The list price includes accessories.

The list price is reduced for capital contributions made by the employee up to £5,000.

Special rules may apply to cars provided for disabled employees.

Car Fuel Benefit

Car fuel benefit applies if an employee has the benefit of private fuel for a company car.

The benefit is calculated by applying the percentage used to calculate the car benefit by a 'fuel charge multiplier'.

The charge is proportionately reduced if provision of private fuel ceases part way through the year. The fuel benefit is reduced to nil only if the employee pays for all private fuel.

Fuel charge multiplier: £28,200

Van Benefit

Van benefit is chargeable if the van is available for an employee's private use.

A fuel benefit may also be chargeable if an employee has the benefit of private fuel paid for in respect of a company van.

The charges do not apply to vans if a 'restricted private use condition' is met throughout the year.

A reduced benefit charge may apply to vans which cannot emit CO2 when driven.

Van benefit: £4,020

Fuel benefit: £769

Advisory Fuel Rates for Company Cars

Advisory rates only apply where employers reimburse employees for business travel in a company car or require employees to repay the cost of fuel used for private travel in a company car.

If the rate paid per mile of business travel is no higher than the advisory rate for the particular engine size and fuel type of the car, HMRC will accept that there is no taxable profit and no Class 1 NIC liability.

Advisory rates are issued quarterly.

Mileage Allowance Payments (MAPs) for employees

MAPs represent the maximum tax free mileage allowances an employee can receive from their employer for using their own vehicle for business journeys.

An employer is allowed to pay an employee a certain amount of MAPs each year without having to report payments to HMRC.

If the employee receives less than the statutory rate, tax relief can be claimed on the difference.

Who Qualifies for Car Benefits and Allowances?

Who Qualifies for Car Benefits and Allowances?

Car benefits and allowances generally apply to employees who use a car for business travel or are provided with a company car as part of their job package.

Company Cars:
Any employee or company director can be offered a company car if their employer provides one. This is common for sales staff, senior managers, or anyone whose role involves regular business travel.

Car Fuel Benefit:
Employees who have a company car can also receive fuel for private use, but this creates an extra taxable benefit. Some employers cover only business fuel to avoid this.

Mileage Allowances:
Employees and directors who use their own private car for business journeys can claim approved mileage allowances. This includes travel to clients or other work locations, but not commuting to a regular workplace.

Who Doesn’t Qualify:
Self-employed individuals don’t usually get car benefits through PAYE but can claim business mileage as an expense. Commuting costs and purely personal journeys are never tax-free or claimable.

Knowing who qualifies helps employers provide the right support and ensures employees claim only what they’re entitled to.

How to Report Car Benefits and Allowances

Employers must report most car benefits and allowances to HMRC to make sure the right tax and National Insurance is paid.

Company Cars and Fuel Benefit:
If you provide a company car or pay for fuel for private use, you’ll need to calculate the benefit-in-kind (BIK) value using HMRC’s rates. Report the benefit through payroll (payrolling benefits) or submit a P11D form for each affected employee after the tax year ends. You must also pay Class 1A National Insurance on the value of the benefit.

Mileage Allowances:
If you pay mileage allowances up to HMRC’s approved rates, you don’t need to report them they’re tax-free. If you pay above the approved rates, the extra amount counts as taxable income and should be reported through payroll or a P11D.

Keep Records:
Keep detailed records of company cars, fuel usage, employee mileage claims, and any contributions the employee makes towards private use. HMRC can ask for evidence to check your calculations.

Employees Claiming Relief:
If an employee gets paid less than the approved mileage rates for using their own car, they can claim Mileage Allowance Relief for the difference through Self-Assessment or by contacting HMRC.

Reporting car benefits and allowances correctly helps avoid unexpected tax bills, penalties, or compliance issues later on.
