Frequently Asked Questions
What are benefits-in-kind?
Benefits-in-kind (BIK) are non-cash benefits provided by employers that have a monetary value and are subject to tax. Examples include company cars, private medical insurance, and interest-free loans.
How is company car tax calculated?
Company car tax is calculated using the car's list price (P11D value), multiplied by a percentage based on CO2 emissions, and then multiplied by your marginal tax rate. For 2025/26, percentages range from 2% for zero-emission cars to 37% for high-emission cars.
Do I pay tax on private medical insurance provided by my employer?
Yes, the cost of private medical insurance paid by your employer is added to your taxable income and taxed at your marginal tax rate. However, you may benefit from the insurance itself, which could be valuable.
Are pension contributions taxable benefits?
No, employer pension contributions are not taxable benefits. In fact, you may receive tax relief on your own pension contributions. Pension contributions are generally the most tax-efficient benefit.
What is the tax on interest-free loans from my employer?
If your employer provides an interest-free or low-interest loan, you'll pay tax on the benefit of cheap credit. The taxable amount is calculated as the difference between the interest you pay (if any) and the official interest rate set by HMRC (currently 2.25% for 2025/26).
Are cycle to work schemes taxable?
Cycle to work schemes are generally tax-free up to certain limits. The scheme allows you to purchase a bicycle and cycling equipment through salary sacrifice, reducing your tax and NI contributions while promoting healthy commuting.
How do benefits-in-kind affect my tax code?
Benefits-in-kind are typically reported to HMRC by your employer on a P11D form. HMRC will adjust your tax code to collect the tax due on these benefits throughout the tax year, reducing your tax-free personal allowance.
Can I opt out of taxable benefits to reduce my tax?
Whether you can opt out depends on your employment contract and company policy. However, even if you decline a benefit, if it's available to you, HMRC may still tax you on it. Always check with your employer and HMRC if you're unsure.
Are childcare vouchers taxable?
Childcare vouchers from employer schemes are generally tax-free up to certain limits. However, the childcare voucher scheme closed to new applicants in October 2018. Tax-Free Childcare is now the main government scheme for childcare support.
How can I calculate the tax impact of my benefits-in-kind?
Your employer should provide a P11D form showing the cash equivalent of your benefits-in-kind. Multiply these amounts by your marginal tax rate to calculate the tax due. For detailed calculations, use our Tax Calculator or wait for this calculator to be fully developed.
