Beneficial loans
There is a taxable benefit where an employee is provided with an interest free loan or where the interest rate payable is below the official rate of interest of 2.25%. There are two alternative methods of calculating the taxable benefit:
The average method: The average is taken of the amount outstanding at the start of the tax year (or when the loan was made if later) and at the end of the tax year (or when the loan was repaid if earlier). The official rate of interest is then applied to this average.
The strict method: The official rate of interest is applied to the amount outstanding on a monthly basis.
If no repayments have been made during the tax year and if no changes to the amount lent have taken place during the tax year, both methods will produce the same result.
The average method applies unless either the employee or HM Revenue and Customs (HMRC) elects for the strict method. In an exam context, both methods should be calculated even if one party opts for the strict method. However, a question might instruct you to use just one method to save having to produce unnecessary workings. Also, in reality, HMRC only elect for the strict method when it will make a significant difference.
