Benefit in Kind Calculator

Employers must pay Class 1A National Insurance at 13.8% on the cash equivalent of most taxable benefits, such as company cars or private medical insurance. This rate applies to the total value of the benefit after any employee contributions have been deducted. There is no earnings threshold for Class 1A NICs, meaning the full taxable value is subject to this charge.

The taxable benefit is calculated by multiplying the car's list price by its P11D percentage, which is based on the vehicle's CO2 emissions and fuel type. For electric vehicles in 2026/27, the P11D percentage remains at 2%, while higher-emission petrol and diesel cars will have significantly higher percentages. Employers must report this value on form P11D by 6 July following the end of the tax year.

Yes, employees can receive up to £30,000 in termination payments tax-free, provided the payment is not contractual. Additionally, trivial benefits costing no more than £50 per item per year are exempt from tax and NICs if they are not cash vouchers or rewards for work performance. These exemptions apply provided the total value of trivial benefits does not exceed £300 per employee per tax year.

While the standard employer NIC rate is 15% on earnings above £5,000, this does not apply to benefits in kind. Instead, employers pay Class 1A NICs at a flat rate of 13.8% on the total taxable value of the benefit. This charge is separate from the employee's income tax liability and must be paid annually by 19 July.

Employees are taxed on the annual value of the accommodation, which is generally the rental value, plus any additional costs incurred by the employer such as repairs or insurance. If the property cost exceeds £75,000, the benefit is also calculated on the interest paid on the loan used to purchase it. This value is reported on the P11D form and subject to both income tax and Class 1A NICs.
