What is Beneficial Loan?
A loan from an employer to an employee at below-market interest rate. If the total loan exceeds £10,000, the difference between the official rate and what you pay is a taxable benefit-in-kind.
Full Definition
A beneficial loan arises when an employer lends money to an employee at an interest rate below HMRC's official rate. For 2026/27 the official rate is 2.25%. If the total of all loans from the employer to the employee exceeds £10,000 at any point during the tax year, the employee is taxed on the notional interest saving as a benefit-in-kind. The taxable benefit is calculated as: (official rate minus the rate actually charged) multiplied by the average loan balance during the year. For example, if an employee has a £30,000 interest-free loan, the taxable benefit is £30,000 x 2.25% = £675. This amount is reported on a P11D form and is subject to Income Tax via the employee's tax code or Self Assessment. The employer also pays Class 1A National Insurance at 13.8% on the value of the benefit. Qualifying loans are exempt from the beneficial loan rules: these include loans used to purchase shares in an employee-controlled company, and employer-provided student loans (though the latter are very rare). Where a director borrows from their own company, Section 455 Corporation Tax may also apply if the loan is not repaid within nine months of the company's year-end. Directors should take care to charge interest at or above the official rate to avoid both the P11D charge and any S455 exposure. Keeping records of loan balances throughout the year is essential for accurate P11D completion.
