Employee Benefits

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.

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.

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.

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.

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.

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.

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.

Advisory fuel rates are intended to reflect actual average fuel costs and are updated quarterly. The rates can be used by employers who reimburse employees for business travel in their company cars or where employees are required to repay the cost of fuel used for private travel. HMRC accepts there is no taxable profit and no Class 1A National Insurance on reimbursed travel expenses where employers pay a rate per mile for business travel no higher than the published advisory fuel rates.

Employees can also use the advisory fuel rates to repay the cost of fuel used for private travel. In this case, HMRC will accept there’s no fuel benefit charge. The advisory rates are not binding if you the employer can demonstrate that employees cover the full cost of private fuel by repaying at a lower rate per mile.

The latest advisory fuel rates became effective on 1 September 2020. Fuel rates are reviewed four times a year with changes taking effect on 1 March, 1 June, 1 September and 1 December. You can use the previous rates for up to 1 month from the date the new rates apply.

The new rates are as follows:

Hybrid cars are treated as either petrol or diesel cars for this purpose.

Advisory Electricity Rate

HMRC accepts that if you pay up to 4p per mile when reimbursing your employees for business travel in a fully electric company car there is no profit. While electricity is not considered a fuel for tax and NICs purposes, the Advisory Electricity Rate is now published quarterly alongside the other advisory fuel rates.

Temporary changes to EMI working time arrangements will ensure that individuals who are furloughed or who have their working hours reduced below the current statutory working time requirement for EMI as a result of coronavirus (COVID-19) will retain the tax advantages of the scheme. These changes will apply for a limited period and will have effect from 19 March 2020 until 5 April 2021.

The use of the EMI can help small growing companies to attract and retain sought after employees. The EMI allows employees to buy shares free of Income Tax and NICs on the difference between the amount paid for shares when an option is used and the actual value at the time.

The value of shares over which options may be held by an employee under the EMI scheme is currently £250,000 in a 3-year period. In addition, the shares must be in an independent trading company that has gross assets not exceeding £30 million, has fewer than 250 employees and operates a ‘qualifying’ trade.

Companies that work in 'excluded activities' aren’t allowed to offer EMIs. Excluded activities include:

• banking
• farming
• property development
• provision of legal services
• ship building
