Employees in the UK are chargeable to income tax on their net taxable earnings. These earnings are made up of the employees’ cash earnings, such as their salaries, wages and any bonuses, as well as any benefits-in-kind they might receive.

Benefits-in-kind is non-cash earnings that are given to an employee in addition to their wages. Common examples are medical insurance and company cars.

The default rules

The value of the benefit is the ‘cash equivalent’ of the benefit. The cash equivalent is the amount that the benefit-cost the employer, less any amounts that the employee contributed towards it. The cost to the employer may be an external cost, such as providing membership to a club, or an internal cost, such as providing a product or service that the employer produces.

An example of an external cost would be the employer providing medical insurance to the employee. If this insurance costs the employer £2,000 per year, this would be the cost to the employer. If the retail value of the policy was £2,000, but the employer received a discount such that it only had to pay £1,500 for the employee’s policy, the cost would be £1,500, as this is what it actually cost the employer.

Where the benefit being provided was produced in-house, the cost remains the cost to the employer rather than the external selling price or any other contrived value.

Other rules

Not all benefits, however, are able to use the default rule. Company cars are taxable depending on a combination of factors, including the car’s CO2 emissions. The emissions level gives a percentage that is applied to the list price in establishing the benefit-in-kind. The same percentage is used to value the fuel benefit. Living accommodation depends on whether the property is rented or owned but is generally based on the annual value. There is an extra charge where the property’s historical cost was over £75,000.
Other valuation methods are used for interest-free employee loans, employees using and being gifted employer-owned assets and employer-provided vans.
