Director’s Loan Accounts (DLAs) are a common feature in UK owner-managed businesses, offering a flexible way to handle funds between a director and their limited company. However, they are subject to strict HMRC regulations and can trigger significant tax charges if not managed correctly. This guide provides a comprehensive overview of the rules, potential tax liabilities, and best practices for maintaining compliance.
The Personal Tax Charge: Benefit in Kind (BIK)
In addition to the company’s potential S455 liability, the director may face a personal tax charge if they receive a “beneficial loan” from the company.
Trigger: A benefit in kind (BIK) arises if the total outstanding loan to a director exceeds £10,000 at any point during the tax year, and the director pays no interest, or pays interest at a rate below HMRC’s ‘official rate of interest’.
Calculation: The taxable benefit is calculated by applying the official rate of interest to the loan amount for the period it was outstanding.
HMRC Official Rate of Interest: For the 2024/25 tax year, this rate is 2.25%. This rate is reviewed annually and can change.
Tax Consequences:
1. Income Tax for the Director: The calculated benefit is treated as part of the director’s employment income and is subject to income tax at their marginal rate.
2. National Insurance for the Company: The company is required to pay Class 1A National Insurance Contributions (NICs) on the full value of the benefit. The rate for 2024/25 is 13.8%.
Avoiding the BIK: This tax charge can be avoided entirely if the director pays interest on the loan to the company at a rate equal to or greater than HMRC’s official rate.
Key Risks and Anti-Avoidance Rules

1. Cash Flow Impact: The 33.75% S455 charge represents a significant cash outflow for the company. While refundable, the delay in reclaiming the tax can strain working capital.
2. “Bed & Breakfasting” (Loan Recycling): HMRC has specific anti-avoidance rules (s464C CTA 2010) to prevent directors from repaying a loan just before the S455 deadline only to withdraw the funds again shortly after.

The 30-Day Rule: If a director repays £5,000 or more of a loan and then, within 30 days, withdraws £5,000 or more, the repayment is matched to the new withdrawal. This means the original loan is treated as not having been repaid, and the S455 charge will still apply.
Arrangements Rule: This rule is broader and applies where, at the time of a repayment, there is an arrangement for a future withdrawal.

3. Insolvency Risk: If a company becomes insolvent, an overdrawn DLA is considered an asset that the insolvency practitioner is legally obligated to recover for the benefit of the company’s creditors. This means the director is personally liable to repay the debt to the company. The protection of limited liability does not apply to this personal debt.
4. Disclosure Requirements: Under the Companies Act 2006, details of any loans to directors must be disclosed in the notes to the company’s annual accounts, regardless of the amount.

What is a Director’s Loan Account?
A DLA is a record kept in the company’s accounts that tracks all money taken from or paid into the company by a director, outside of regular salary, dividends, or expense repayments.
DLA in Credit: When a director lends money to the company, the DLA is in credit. The company owes the director money, and this is treated as a liability on the company’s balance sheet.
DLA Overdrawn: When a director borrows money from the company, the DLA is overdrawn. The director owes the company money, creating a company asset. It is this overdrawn status that attracts HMRC’s attention and can lead to tax charges.
The Corporate Tax Charge: Section 455
If a director’s loan is not repaid in full by a specific deadline, the company itself is liable for a substantial tax charge under Section 455 of the Corporation Tax Act 2010 (CTA 2010).
Trigger: The charge applies if the DLA is still overdrawn nine months and one day after the company’s financial year-end.
The Rate:
- For loans made on or after 6 April 2022, the S455 tax rate is 33.75%.
- For loans made between 6 April 2016 and 5 April 2022, the rate is 32.5%.
This rate is intentionally high as it is linked to the dividend upper tax rate, discouraging directors from using loans as a long-term, tax-free method of extracting profits. This tax is payable by the company as part of its Corporation Tax liability and is reported on the CT600A supplementary form.
Is S455 Tax Refundable?
Yes, S455 tax is a temporary charge. The company can reclaim the tax it has paid once the underlying loan has been repaid, written off, or released.
However, the reclaim process is not immediate. A claim for repayment cannot be made until nine months and one day after the end of the corporate accounting period in which the loan was repaid. This can lead to a significant cash flow disadvantage for the company, as the funds can be tied up with HMRC for a considerable time.
Best Practices for Managing DLAs
Repay with External Funds: To avoid falling foul of the “bed & breakfasting” rules, it is safest to repay a DLA using personal funds that are not immediately drawn back out of the company.
Maintain Meticulous Records: Use accounting software to track every transaction flowing through the DLA to ensure the balance is always known and accurate.
Formalise Loans: For any significant loan, create a formal loan agreement that is approved by the board and recorded in the company’s minutes. This should specify the loan amount, interest rate, and repayment terms.
Monitor the £10,000 BIK Threshold: If a director’s loan is approaching or exceeds £10,000, ensure interest is charged at the official rate and paid by the director to avoid BIK charges.
Respect the 9-Month Deadline: The most critical deadline is nine months and one day after the financial year-end. Plan to clear any overdrawn balance before this date to prevent the S455 charge.
Plan Profit Extraction: Consider whether a loan is the best method for extracting funds. Often, a combination of salary and dividends is more tax-efficient and administratively simpler.
