If your employer lends you money at no interest, or at a rate below HMRC's official rate of interest, the saving can count as a taxable benefit-in-kind. This guide explains the small loans exemption, how the benefit is calculated, and how it is reported.
What Counts as a Beneficial Loan
A beneficial loan is a loan provided, or arranged, by an employer for an employee or director at no interest or at a rate below HMRC's official rate of interest -- a rate HMRC sets and can change during the tax year. The value of the benefit is the interest you would have paid at the official rate, less any interest you actually paid.
The Small Loans Exemption
Most everyday cheap loans from an employer -- such as a season ticket loan -- never trigger a taxable benefit at all, because of a small loans exemption: provided the total outstanding balance of all qualifying cheap or interest-free loans from the same employer stays below the exemption threshold throughout the year, no beneficial loan benefit arises. Loans from connected employers, or multiple loans to the same employee, are generally added together for this test, so it is worth checking the combined balance rather than looking at each loan in isolation.
Calculating the Taxable Benefit
Where the exemption does not apply, the benefit is generally worked out by comparing the interest you actually paid against what you would have paid at the official rate of interest, using either a simpler averaging method based on the loan balance at the start and end of the year, or a more precise method that tracks the balance and dates of any drawdowns and repayments during the year. Employers can choose whichever method produces the fairer result, and employees can sometimes elect for the alternative method if it gives a lower figure.
How It Is Reported
The taxable value of a beneficial loan is reported by the employer on form P11D, unless the benefit is being payrolled, in which case it is taxed through your regular pay instead. Either way, the value is added to your other taxable income for the year, and the employer separately pays Class 1A National Insurance on the benefit.
Directors’ Loan Accounts
If a director owes their own company money through an overdrawn director's loan account and is charged no interest, or interest below the official rate, this is generally treated as a beneficial loan benefit-in-kind in exactly the same way as any other employer-provided loan. This sits alongside -- not instead of -- any separate corporation tax charge the company itself may face on the outstanding loan balance, so both angles need considering together.
Frequently Asked Questions
What is a beneficial loan for tax purposes?
A beneficial loan is one provided (or arranged) by an employer to an employee or director at no interest, or at an interest rate below HMRC's official rate of interest. The difference between what you actually pay and what you would have paid at the official rate is treated as a taxable benefit-in-kind.
Is every loan from an employer taxed as a benefit-in-kind?
No. There is a small loans exemption -- if the total outstanding balance of all cheap or interest-free loans from your employer stays below the exemption threshold throughout the tax year, no beneficial loan benefit arises at all, which removes most everyday small loans (such as a season ticket loan) from the rules entirely.
What counts towards the small loans exemption threshold?
All qualifying cheap or interest-free loans from the same employer (or connected employers) to the same employee are generally added together for the exemption test, so several small loans that individually look modest can combine to exceed the threshold and bring the whole benefit into charge.

How is the taxable benefit calculated if the loan exceeds the exemption?
HMRC compares the interest you actually paid over the tax year with what you would have paid at the official rate of interest on the loan balance, using either the averaging method or the more precise strict (alternative) method -- the difference is the cash equivalent of the benefit, added to your other taxable income.
How is a beneficial loan benefit reported?
The employer reports the benefit on form P11D (or payrolls it through the payroll system if registered to do so), and it is taxed through your Self Assessment or PAYE coding. The employer also pays Class 1A National Insurance on the value of the benefit.
Does a director's loan account count as a beneficial loan?
Yes -- if a director owes their own company money (an overdrawn director's loan account) and is charged no interest or below the official rate, this is generally treated as a beneficial loan benefit-in-kind in the same way as any other employer loan, in addition to any separate corporation tax charge (such as under section 455) that can apply to the company.
Are loans for specific purposes ever exempt regardless of amount?
Certain qualifying loans, such as some loans used to buy particular types of season tickets or for specific relocation purposes, may have their own separate treatment or exemption conditions -- check the specific type of loan against current HMRC guidance rather than assuming the general small loans exemption is the only relief available.
What happens if the loan is written off rather than repaid?
If an employer writes off a loan rather than requiring repayment, the amount written off is normally treated as additional taxable income (and can also trigger National Insurance), separate from -- and usually larger than -- the ongoing beneficial loan interest benefit charged while the loan was outstanding.
Can I avoid the benefit-in-kind by paying interest at the official rate myself?
Yes -- if you pay interest to your employer at least equal to HMRC's official rate of interest for the whole period the loan is outstanding, no taxable beneficial loan benefit arises, since there is no shortfall between what you paid and what the official rate would have required.
Does the official rate of interest change during the tax year?
HMRC reviews the official rate of interest regularly and it can be changed part-way through a tax year, so a loan can be measured against more than one rate within the same year -- the averaging and strict calculation methods both take any in-year change into account when working out the benefit.
