The short answer
UK 2026/27 tax on interest-free and low-interest employee loans: the £10,000 exemption, official rate, P11D reporting and Class 1A National Insurance.
An employer loan can be a taxable Benefit in Kind even when you receive no cash interest or repayment bonus. The usual issue is a loan that is interest-free or charged below HMRC's official rate. HMRC compares the interest you actually pay with the interest calculated using the official rate, and the difference can become taxable employment income.
For 2026/27, HMRC's published official rate is 3.75% from 6 April 2026, subject to the quarterly review process. That rate is used to value many employment-related loans, but it is not a promise that the rate will remain unchanged throughout the tax year. Check the current HMRC rate before finalising a payroll or P11D calculation.

What is a beneficial loan?
A beneficial loan is broadly an employment-related loan made available at no interest or at a rate below HMRC's official rate. The rules can cover a loan advanced, arranged, facilitated, guaranteed or taken over by an employer or a connected business. They can also cover a loan made to an employee's spouse or relative when it is provided because of the employment.
The label used by the employer does not decide the tax treatment. An “employee advance”, staff loan, season-ticket loan, relocation loan or loan to help with a personal purchase may all need to be tested against the beneficial-loan rules. A genuine reimbursement of business expenses is a different question and should not be treated as an employee loan without checking the facts.
If the company is lending to a director or participator from a company account, there may also be director-loan and corporation-tax consequences. See the separate guide to Director's Loan Accounts 2026/27 rather than applying this employee summary to a shareholder loan.
How the taxable benefit is calculated
The basic idea is:
Taxable loan benefit = official-rate interest − interest paid by the employee
The calculation is not normally based simply on the amount originally borrowed. The balance, the dates it was outstanding, repayments, further advances and interest paid during the tax year all matter. HMRC provides detailed methods for valuing the benefit, including an averaging method for loans outstanding through the year and an alternative precise method where the balance changes.
Simple illustration
Suppose an employee has an interest-free loan of £20,000 throughout a period when the applicable official rate is 3.75%:
| Item | Illustrative amount |
|---|---|
| Loan balance | £20,000 |
| Official-rate interest at 3.75% | £750 |
| Interest paid by employee | £0 |
| Illustrative taxable benefit | £750 |
If the employee pays £200 of qualifying interest, the simple difference is £550. This is an illustration of the valuation concept, not a substitute for the employer's P11D calculation. A loan opened or repaid part-way through the year, or one with changing balances, needs a time-based calculation.
The employee does not usually receive the £750 as salary. Instead, it is a taxable value added to employment income. For a basic-rate taxpayer, £750 could create approximately £150 of Income Tax; for a higher-rate taxpayer, approximately £300. Actual tax depends on the taxpayer's band, allowances, Scottish rates where applicable, tax code and other benefits.
When the £10,000 exemption can apply
HMRC says a beneficial-loan exemption may apply where the combined outstanding value of relevant loans to the employee stays below £10,000 throughout the whole tax year. The test is not a £10,000 tax-free allowance that can be exceeded with tax only on the excess. It is an exemption condition, so crossing the threshold can change the reporting position for the loans covered by the rules.
The combined test matters where an employee has more than one loan, for example:
| Loan | Outstanding amount |
|---|---|
| Season-ticket loan | £4,000 |
| Relocation loan | £5,500 |
| Combined amount | £9,500 |
In this illustration the combined balance is below £10,000, but the employer still needs to confirm that the loans are within the exemption and that the balance did not exceed the threshold at any point. A later advance of £1,000 would take the combined amount to £10,500 and require the employer to revisit the treatment.
The exemption does not remove the need to check other rules. HMRC lists separate conditions for certain fixed-rate loans, loans available to the general public, qualifying loans and loans made in the normal course of an individual domestic or family relationship. A company controlled by the lender is not automatically treated like a private family loan just because the same people own it.
When the loan is not taxable
Not every employer loan produces a taxable benefit. Depending on the facts, HMRC identifies possible exemptions for:
- loans where the combined outstanding balance remains below £10,000 for the tax year;
- a fixed-term, fixed-rate loan whose rate was at least the official rate when the loan was made;
- loans offered on identical terms to the general public, which can be relevant for commercial lenders;
- qualifying loans where the interest would qualify for full tax relief; and
- some loans made in an individual's genuine domestic or family relationship, rather than by a company they control.
These are fact-sensitive conditions. For example, a loan for a qualifying purpose may have a different result from a loan for a personal car, and a salary-sacrifice arrangement can change the reporting analysis. Ask payroll for the legal basis of any exemption instead of assuming that an employee discount or staff benefit is automatically tax-free.
How it appears on your payslip or P11D
The employer normally deals with the reporting. For a non-exempt beneficial loan, HMRC says the employer should report the benefit on form P11D and pay Class 1A National Insurance on the taxable value. The Class 1A charge is the employer's liability; it is not the same as employee Class 1 National Insurance deducted from salary.
The Income Tax can reach the employee in different ways:
| Employer process | What the employee may see |
|---|---|
| P11D reporting | A later tax-code adjustment or a tax calculation that includes the benefit |
| Payrolled benefits | More PAYE deducted during the year as the benefit is processed |
| Loan repaid or balance changes | A changed benefit value in the next employer calculation |
Keep the loan agreement, opening balance, repayment dates, interest charged and any P11D. If the loan is repaid, ask when payroll will remove or reduce the benefit. A tax code can continue to reflect an old benefit until HMRC receives corrected information.
What happens if the loan is written off?
A loan that the employer writes off is not simply the same as a normal low-interest benefit. HMRC says loans written off must be reported and the employer must deduct and pay Class 1 National Insurance on the value; PAYE Income Tax is not handled in exactly the same way as for an ordinary beneficial loan. The precise treatment depends on the circumstances and whether the amount is earnings or another taxable payment.
Do not ask payroll to remove a written-off balance as if it were an ordinary repayment. The date, legal form and reason for the write-off should be documented, and an adviser may be needed where the employer is also a close company or the employee is a director.
A practical employee checklist
Check an employer loan
- 1Ask for the loan agreement, opening amount, interest rate and repayment schedule.
- 2List every employment-related loan from the employer or connected companies and check the highest combined balance during 2026/27.
- 3Confirm which official rate and valuation method payroll is using, especially if the balance changed during the year.
- 4Ask whether the £10,000 exemption or another specific HMRC exemption applies and request the reason in writing.
- 5Check whether the benefit is payrolled or will appear on a P11D, then compare the reported value with your records.
- 6Tell payroll promptly about a repayment, new advance, interest payment, change of employer or written-off amount.
Use the UK Salary Calculator to illustrate the marginal Income Tax effect of a taxable benefit, but do not enter the loan balance as extra salary. The relevant input is the taxable benefit calculated by the employer, alongside your actual employment income and other benefits.
Year-end and mid-year checks
Employers should review each loan when it is advanced, repaid, varied or written off. Reconcile the opening balance, further advances, repayments, interest received and highest combined balance to the payroll or P11D working paper. If several connected companies lend to the same employee, include the information needed to test the combined exemption rather than relying on one company's ledger alone.
Employees should keep their own schedule as well. Record every payment and interest charge, compare the balance with the P11D or payrolled figure and ask payroll about differences promptly. A loan that falls below £10,000 at year end may still have exceeded the threshold earlier in the tax year, while a loan that is repaid before the reporting date may still have created a benefit for the period it was outstanding.
The official rate is a valuation input, not the interest rate that the employee must pay. If HMRC changes the official rate during the year, check which rate applies to each relevant period and keep the dated HMRC publication used. Do not carry a prior year's rate into 2026/27 or a later quarter without checking the current official-rates page.
Keep the dated calculation with the loan records.
Reconcile the Loan to the Annual Benefit
The best control is a timeline, not just an opening and closing balance. Record each advance, repayment, interest payment, rate change, connected-company transfer and write-off date. Then compare the highest combined outstanding balance with the exemption conditions and calculate the benefit for the periods in which the loan was available. A loan repaid before 5 April can still create a taxable benefit for the earlier part of the year.
Separate the employee’s tax from the employer’s National Insurance. The benefit may be included through payroll or reported on P11D, while Class 1A is generally the employer liability. If the benefit is payrolled, compare the cumulative taxable amount with the P11D-style working paper; if it is not payrolled, check the tax-code adjustment and annual return position. Do not treat a tax code as proof that the underlying balance was valued correctly.
For multiple loans, obtain a connected-employer schedule before applying the £10,000 test. If the loan is transferred, refinanced, written off or changed into a director or participator loan, close the employee-loan calculation and open the appropriate review. Keep the agreement, ledger, interest receipts, payroll output and correction approval together so the final reported figure can be reproduced.
