Pay back private fuel costs and avoid tax charge

Employees who receive fuel from their employer for private use in a company car can avoid paying the car fuel benefit charge by reimbursing the full cost of the private fuel. This process, known as "making good," requires the employee to repay the employer for private fuel no later than 6 July following the end of the tax year. For the 2025–26 tax year, the repayment must be completed by 6 July 2026.

If the repayment is not made by the deadline, the employee becomes liable for the car fuel benefit charge. This charge is calculated based on the vehicle’s CO2 emissions and the car fuel benefit multiplier. The charge applies regardless of the actual amount of private fuel used, making it potentially costly for employees who only use a small amount of fuel for private journeys, such as commuting.

To avoid the car fuel benefit tax the employee must reimburse the total cost of all private fuel used during the year, including fuel used to travel to and from work. Keeping accurate mileage records is essential. HMRC will only accept that no benefit has arisen if the full cost is repaid by the deadline. In many cases, repaying the private fuel cost can be more financially beneficial than paying the fuel benefit tax charge.

New rules for working from home from April 2026

The rules on claiming tax relief for working from home are changing for the new 2026-27 tax year. In most cases, employees will no longer be able to claim relief for homeworking, although claims can still be made for the previous four tax years. The removal of the tax relief was announced in the Autumn Budget last year and it is estimated that some 300,000 taxpayers will be affected by the change.

Relief is only available if you have to work from home for your job, for example, if your role requires you to live far from the office or your employer does not provide an office to work from. You cannot claim tax relief if you choose to work from home, including under flexible arrangements allowed by your contract.

Where eligible, you can claim for work-related household costs such as business phone calls or the additional gas and electricity used in your work area. You cannot claim for costs used for both private and work purposes, such as rent or broadband.

Tax relief can be claimed at £6 a week or for the exact amount spent, and the relief is calculated based on your income tax rate. For example, if you pay the 20% basic rate of tax and claim tax relief on £6 a week, you will get £1.20 per week in tax relief (20% of £6). Evidence is required for claims, including receipts or bills if claiming actual costs.

Claims for the current and previous tax years can be made through https://www.tax.service.gov.uk/claim-tax-relief-expenses/claim-any-other-expense. If you complete a self-assessment tax return, you must claim through your tax return instead. The new rules mark a return to stricter pre-pandemic rules when tax relief was only available when working from home was required and not optional.

Company car expenses and benefits – what’s exempt?

While company cars often come with tax implications, there are specific situations where the associated benefits may be exempt. There are circumstances where it can be possible to offer employees car benefits that are exempt from tax.

Exempt expenses and benefits include the following:

• Business-only use: This rule has been the subject of much case law over the years, but it has generally been established that to qualify for VAT recovery the car must not be available for any private use. This means that the car should only be available to staff during working hours for employment related duties or to travel to a temporary workplace. The business must also clearly tell their employees not to use the vehicle for private journeys and check that they don’t.
• Adapted vehicles for disabled employees: These cars are exempt if the only private use is for journeys between home and work and for travel to work-related training.
• Fuel paid by employees: The fuel benefit is removed when an employee pays for all their private fuel use or if the employer pays and the employee reimburses the amount (during the tax year).
• ‘Pool’ cars: Employers are not required to pay or report on 'pool' cars. These are cars that are shared by employees for business purposes only and normally kept on your premises. Employers must ensure the ‘pool’ car rules are properly adhered to.
• Privately owned vehicles: Employers do not have to pay anything on cars that directors or employees own privately.

Proper documentation and compliance are required in order to maintain these exemptions.

The scope of the trivial benefits legislation

The trivial benefits legislation provides a simple and practical tax exemption that allows employers to give small non-cash benefits to employees without triggering tax or National Insurance charges.

To qualify as a trivial benefit, the cost to the employer must not exceed £50 per item. The benefit must not be cash or a cash voucher and must not be provided as a reward for work or as part of the employee’s contractual entitlement. It must also not be provided in recognition of particular services performed. Typical examples include modest gifts such as flowers, a bottle of wine, a meal voucher or a small seasonal gift.

Where these conditions are met, the benefit is exempt from Income Tax, employer’s and employee’s National Insurance and does not need to be reported to HMRC.

For directors of close companies, an additional annual cap applies. Such individuals are limited to £300 of trivial benefits per tax year, calculated as an aggregate of qualifying items. This limit does not apply to ordinary employees.

The rules are designed to reduce administrative burdens and provide clarity, but care is needed. Regular provision of benefits, or benefits that appear linked to performance, can fall outside the exemption.

Used correctly, trivial benefits offer a straightforward way for businesses to reward staff in a tax-efficient and low-compliance manner.

Avoiding the car fuel benefit charge

Employees with company cars may be paying unnecessary tax on private fuel, when reimbursing the cost of private fuel in full can often remove the car fuel benefit charge altogether.

Where an employee is provided with a company car and fuel for private use, the default position is that the employee must pay the car fuel benefit charge. The amount of the charge is calculated based on the car’s CO2 emissions and applied to the car fuel benefit multiplier, which is currently £28,200 and is set to increase to £29,200 for the 2026–27 tax year.

Avoiding the car fuel benefit charge is possible if the employee reimburses their employer for all fuel used for private journeys, a process known as ‘making good’. Private fuel includes all fuel used for commuting to and from work. To do this, employees should keep a record of private mileage and repay their employer using the published advisory fuel rates. These rates are designed to reflect average fuel costs and are updated quarterly.

If properly documented, HMRC will accept that no car fuel benefit charge is due, meaning the employee avoids the income tax liability on the private fuel. In most cases, reimbursing the employer is far cheaper than paying the tax, especially for employees with relatively low private mileage.

The car fuel benefit charge will still apply if it cannot be demonstrated to HMRC that the employee has reimbursed the full cost of fuel used for private journeys, including commuting. To prevent this, employees must maintain a detailed log of private mileage and ensure they make good the cost of all fuel provided for private use.

Taxable company benefits

As an employee, you pay tax on certain company benefits, such as cars, accommodation, and loans. Your employer calculates the tax you owe and deducts it through Pay As You Earn (PAYE). The amount of tax depends on the type and value of the benefit.

Some company benefits are tax-free, including childcare support and meals provided in canteens. Cash payments, however, are treated as earnings and are always subject to tax and National Insurance contributions.

Other taxable benefits you will pay tax on include the following:

Medical Insurance

You usually pay tax on the cost of the insurance premiums if your employer pays for your medical insurance. However, some health benefits are tax-free, including medical insurance while you are working abroad and annual check-ups.

Loans

You may have to pay tax on low-interest or interest-free loans from your employer if the loan is more than £10,000. The tax is calculated on the difference between the interest rate you pay and the official rate of interest set by the Bank of England. You could also be liable for tax if your employer lends money to one of your relatives.

Living Accommodation

If you (or one of your relatives) lives in accommodation provided by your employer, you may need to pay tax. The calculation depends on whether the accommodation costs are more than £75,000. You might not have to pay tax if the accommodation is provided so you can perform your job or do it more effectively, for example, agricultural workers living on farms.

Tax and trivial benefits

There is a trivial benefit-in-kind (BiK) exemption that applies to small, non-cash gifts (such as a bottle of wine or a bouquet of flowers) that are occasionally given to employees.

This exemption enables employers to offer modest, tax-efficient rewards while simplifying the administration of BiKs. The BiK exemption allows businesses to recognise employees in a small way without creating additional reporting obligations or tax liabilities.

Trivial benefits are a simple and effective way to provide gestures of goodwill or recognition, as long as they are not given as a reward for work performed or duties carried out. Typical qualifying occasions include events such as a marriage, the birth of a child or other personal landmarks.

Employers also benefit since these trivial BiKs do not need to be included in PAYE settlement agreements or reported on P11D forms, and they are exempt from Class 1A National Insurance contributions.

The tax exemption applies to trivial BiKs where the benefit:

• costs £50 or less;
• is not cash or a cash voucher;
• is not a reward for work or performance; and
• is not in the terms of an employee’s contract.

Trivial benefits provided through a salary sacrifice arrangement are not exempt from tax. In such cases, the employer must report them on form P11D, using the higher of the amount of salary the employee gave up, or the cost of the trivial benefit provided.

For directors or officeholders of close companies (and their families), there is an annual cap of £300 on trivial benefit gifts. The £50 limit still applies per gift but allows up to £300 of non-cash benefits per person each year. If any single gift exceeds £50, the full value becomes taxable.

Taxable benefits for use of company car

The tax you pay on the use of a company car depends largely on its CO2 emissions, so choosing a lower emission or electric vehicle can make a significant difference to your overall tax cost.

The benefits in kind (BIK) tax on company cars can be quite significant, with taxable rates ranging from 3% to 37% of the car’s list price when new. The rate depends on various factors, primarily the car’s CO2 emissions and fuel type. For instance, a petrol fuelled car emitting 155 g/km of CO2 or more would be taxed at the highest rate of 37% of its original list price. In contrast, an electric car with a range of 130 miles or more could benefit from the lowest rate of just 3%, significantly reducing the taxable benefit.

This creates a strong incentive for those driving company cars to switch to electric vehicles, as they would experience a noticeable reduction in their tax liability. This shift not only benefits the employees but also employers, who will see a decrease in Class 1A National Insurance contributions. These contributions are based on the total value of benefits provided in a tax year, so switching to electric vehicles helps lower overall costs for the employer.

Diesel cars attract an additional 4% supplement if they do not meet the Real Driving Emissions 2 (RDE2) standard. However, the supplement is removed entirely for diesel vehicles that are RDE2 compliant. The maximum BIK rate, including any diesel supplement, remains capped at 37%.

The taxable benefit is typically calculated based on the car’s manufacturer’s list price, which includes VAT, delivery charges, and number plates. The price considered is the list price on the day before the car is first registered. Any additional accessories fitted to the car also increase the taxable value. There are some exceptions. Employees can also reduce the list price by up to £5,000 if they make a capital contribution towards the cost of the vehicle. Special rules apply to classic cars, which have their own method for calculating the list price.

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.

Claim for a business journey in a private vehicle

Use your own vehicle for work? You could be entitled to a tax-free mileage allowance. Make sure you are not missing out on HMRC-approved rates.

If you use your own car, van, motorcycle, or bicycle for business journeys, you may be entitled to a tax-free mileage allowance from your employer. This is known as a Mileage Allowance Payment (MAP) and is designed to cover the costs of using a personal vehicle for work-related travel. Many employees routinely claim this allowance when driving their own vehicle to visit clients, travel between temporary work locations, or attend off-site meetings.

It’s important to understand that MAPs do not apply to ordinary commuting, that is, travelling to and from your regular place of work. However, where travel is genuinely work-related and qualifies as a business journey, the allowance can be a valuable tax-free benefit.

Employers typically reimburse employees using HMRC’s approved mileage rates, which are designed to reflect reasonable running costs. These rates are as follows:

• Cars and vans:
  • 45p per mile for the first 10,000 business miles in a tax year
  • 25p per mile for each mile over 10,000
• Motorcycles: 24p per mile
• Bicycles: 20p per mile

Where an employee carries a colleague as a passenger during a business journey, an additional 5p per mile per passenger can be claimed provided the journey is for business purposes. This extra allowance is also tax-free when paid by the employer.

If an employer pays less than the approved HMRC rates (excluding the passenger allowance), you may be able to claim the shortfall from HMRC utilising Mileage Allowance Relief.
