What is Director Benefit in Kind (BIK)?

Full Definition

A Benefit in Kind (BIK) is any non-cash benefit provided by a company to a director or employee that has a monetary value. For directors of owner-managed limited companies, common BIKs include: a company car (taxed based on the vehicle's list price multiplied by a CO2-emissions percentage, ranging from 2% for pure electric vehicles to 37% for high-emission petrol cars in 2026/27); private medical insurance (taxed at the annual premium cost); interest-free or low-interest director loans exceeding GBP 10,000 in aggregate (a notional interest benefit is calculated using HMRC's official rate, 2.25% for 2026/27, applied to the loan balance); gym membership or other personal subscriptions; and living accommodation provided by the company. BIKs are reported to HMRC in one of two ways. The traditional route is form P11D, submitted by the employer by 6 July following the tax year end, listing all benefits provided to each director and employee. The alternative is payrolling -- the employer registers with HMRC in advance and adds the taxable value of benefits to the employee's pay each payroll run so that tax is collected in real time through PAYE. Regardless of reporting method, the company must pay Class 1A National Insurance (at 15% for 2026/27) on the total taxable value of all BIKs, with payment due by 22 July. The director pays income tax on the BIK value either through an adjusted PAYE tax code (HMRC reduces the personal allowance to collect tax on the benefit) or via Self Assessment. Separately, if a director's loan account becomes overdrawn and remains unpaid nine months after the company's accounting year end, the company faces an S455 charge of 33.75% of the outstanding balance -- this is a corporation tax charge, not a BIK, but often arises alongside BIK issues in director-managed companies.
