An employee can obtain a benefit when provided with an employment-related cheap or interest-free loan. The benefit is the difference between the interest the employee pays, if any, and the commercial rate the employee would have to pay on a loan obtained elsewhere. These types of loans are referred to as beneficial loans.
There are scenarios where beneficial loans are exempt and employers might not have to report anything to HMRC or pay tax and National Insurance. The most common exemption relates to small loans with a combined outstanding value to an employee of less than £10,000 throughout the whole tax year.
The list also includes loans provided:
in the normal course of a domestic or family relationship as an individual (not as a company you control, even if you are the sole owner and employee)
to an employee for a fixed and invariable period, and at a fixed and invariable rate that was equal to or higher than HMRC’s official interest rate when the loan was taken out
under identical terms and conditions to the public as well (this mostly applies to commercial lenders)
that are ‘qualifying loans’, meaning all of the interest qualifies for tax relief
using a director’s loan account if it is not overdrawn at any time during the tax year.
