If you’re an employee or business owner in the UK, you may have heard the term Benefit in Kind (BIK), but what does it actually mean, and how does it affect your tax?
In simple terms, a Benefit in Kind is a non-cash benefit provided by an employer that still has a tax value. While you may not receive extra money in your payslip, HMRC still considers many benefits as taxable income.
In this guide, we’ll explain what a Benefit in Kind is, how it’s taxed, common examples, and how to stay compliant. If you are looking for a tax advisor in the UK, Kent, get in touch with Clayton Stirling & Co today.
What Is a Benefit in Kind?
A Benefit in Kind (BIK) is any perk or benefit an employer provides to an employee in addition to their salary, where the benefit has a monetary value.
HMRC treats most benefits as taxable because they effectively increase your overall earnings — even if no cash changes hands.
Both employees and employers may have tax or National Insurance responsibilities depending on the benefit provided.
Common Examples of Benefits in Kind
Some of the most common Benefits in Kind in the UK include:
- 🚗 Company cars
- ⛽ Fuel provided for private use
- 🏠 Living accommodation
- 💻 Personal use of company equipment
- 🏥 Private medical insurance
- 📱 Company phones (in some cases)
- 💳 Interest-free or low-interest loans
- 🎟 Gifts or vouchers over HMRC limits
Not all benefits are taxable, but many are, and the rules can vary depending on how the benefit is provided.
Example of a Benefit in Kind in Cash Terms
Imagine an employee earns a salary of £40,000 per year and is also given private medical insurance by their employer, which costs the company £1,200 per year.
Although the employee does not receive this £1,200 in cash, HMRC treats it as a Benefit in Kind because it has a clear monetary value. This means the employee is effectively taxed as if they earned £41,200.
If the employee pays tax at the 20% basic rate, they would pay an additional £240 per year in Income Tax on this benefit (£1,200 × 20%). If they are a higher-rate taxpayer at 40%, the tax due would be £480 per year.
The employer would also need to pay Class 1A National Insurance on the £1,200 benefit, currently charged at 13.8%, which equals £165.60.
How Are Benefits in Kind Taxed?
The way a Benefit in Kind is taxed depends on the type of benefit.
For Employees
- The value of the benefit is added to your taxable income
- You pay Income Tax on it at your normal tax rate
- Tax is usually collected through PAYE, adjusting your tax code
For Employers
- Employers usually pay Class 1A National Insurance
- Benefits must be reported to HMRC
- Most benefits are reported annually using P11D forms
Some benefits can be payrolled, meaning tax is deducted in real time rather than reported after the tax year ends.
How Is a Benefit in Kind Calculated?
Each benefit has its own calculation rules set by HMRC.
For example – Company cars are taxed based on:
- The car’s list price
- CO₂ emissions
- Fuel type
- Medical insurance is taxed on the actual cost to the employer
- Loans are taxed based on the interest saved by the employee
Because calculations can be complex, many businesses rely on an accountant to ensure figures are correct. If you want to find out more about what tax you’ll pay on a company with Benefit in Kind, view this tax calculator from Comcar.
What Happens If Benefits in Kind Are Reported Incorrectly?
When Benefits in Kind are reported incorrectly or not reported at all, it can lead to a range of issues with HMRC. Employees may find their tax codes adjusted unexpectedly, resulting in underpaid tax that must be settled later, sometimes in a single lump sum. For employers, errors can trigger HMRC enquiries, penalties, and interest charges on unpaid Class 1A National Insurance.
In more serious cases, repeated mistakes or omissions may be viewed as non-compliance, increasing the likelihood of future audits. Incorrect reporting can also create administrative headaches, requiring amended P11D submissions and time-consuming correspondence with HMRC to resolve discrepancies.
