Director’s Loan Accounts: Essential Dos and Don’ts for UK SME Owners
- Aug 11
- 5 min read
As a director of a UK limited company, the line between "your money" and "the company’s money" can sometimes feel a little blurred: especially in the early stages of business growth. However, HMRC sees a very clear line. One of the most common areas where SME owners find themselves in hot water is the Director’s Loan Account (DLA).
Whether you are using company funds to cover a personal emergency or lending your own savings to the business to keep cash flow steady, understanding the rules of the DLA is non-negotiable. Get it right, and it’s a flexible financial tool. Get it wrong, and you could face a 35.75% tax charge and a personal tax bill you weren't expecting.
In this guide, we’ll break down exactly how DLAs work in 2026, the critical tax thresholds you need to know, and why you should find an accountant in the UK to keep your records compliant.
What is a Director’s Loan Account (DLA)?
In simple terms, a Director’s Loan Account is a record of the money moving between you (the director) and your limited company that isn't already accounted for as salary, dividends, or expense repayments.
There are two states for a DLA:
In Credit: You have put your own money into the business (perhaps to fund startup costs or a temporary dip in cash flow). The company owes you money.
Overdrawn: You have taken money out of the company that hasn't been declared as a dividend or salary. You owe the company money.
While having a DLA "in credit" is generally straightforward, an overdrawn DLA is where the complexity begins. If you are still deciding on the best way to structure your earnings, it’s worth reading our guide on Dividend Tax 2026/27: The Most Tax-Efficient Way to Pay Yourself.
The Overdrawn DLA: The Danger Zone
Taking a "director's loan" is often seen as a quick way to access cash without the immediate paperwork of a dividend or the National Insurance costs of a salary. However, HMRC monitors these closely to ensure they aren't being used as a way to avoid tax.
If your account is overdrawn at the end of your company’s financial year, you have a limited window to pay it back before significant tax charges apply. This is one of the primary reasons business owners compare accountants for small business: to ensure these balances are managed before the "9-month deadline" hits.
Section 455 Tax: The 2026 Rates
If a loan to a director/shareholder (a "participator" in a close company) remains unpaid 9 months and 1 day after the end of the accounting period, the company must pay Section 455 (S455) tax.
For the 2026/27 tax year, the rates have seen a significant shift:
Loans made before 6 April 2026: Charged at 33.75%.
Loans made on or after 6 April 2026: Charged at 35.75%.
This tax is payable by the company. While you can reclaim this tax from HMRC once the loan is fully repaid, the process can take months, which can cause a massive strain on your business's cash flow.
The £10,000 Threshold and Benefit in Kind (BIK)
Even if you plan to pay the money back within the 9-month window, you still need to watch the "Benefit in Kind" (BIK) rules.
If your total overdrawn balance exceeds £10,000 at any point during the tax year, the loan is treated as a taxable perk. Because the company is effectively giving you an interest-free (or low-interest) loan, HMRC views the "saved interest" as income.
If you cross the £10,000 mark:
The Director: Must report the loan on their Self Assessment and pay personal income tax on the "official rate of interest" (currently set by HMRC).
The Company: Must report the benefit on a P11D form and pay Class 1A National Insurance on the value of the benefit.
This is a classic trap for SME owners who don't track their DLA in real-time. If you are moving from a simpler structure, you might find our comparison of Sole Trader vs Limited Company useful to see if the administrative burden of a DLA is right for you.
The "Bed and Breakfasting" Rule: No Quick Fixes
In the past, some directors tried to bypass S455 tax by repaying the loan just before the 9-month deadline and then immediately withdrawing the money again a few days later. HMRC caught onto this "Bed and Breakfasting" tactic long ago.
Current anti-avoidance rules state that if you repay a loan of £5,000 or more and then take out a new loan within 30 days, the repayment is effectively ignored for tax purposes. You will still be charged S455 tax as if the loan was never repaid.
Essential Dos and Don’ts for Your DLA
To stay on the right side of HMRC, follow these essential guidelines:
The Dos
Do Keep Real-Time Records: Use modern accounting software to track every penny moving between you and the company.
Do Clear Small Balances Yearly: Try to ensure your DLA is back to zero (or in credit) before your financial year-end.
Do Charge Interest: If the loan is over £10,000, consider having the company charge you the HMRC official interest rate. This avoids the Benefit in Kind tax.
Do Find a Specialist: The rules around DLAs are nuanced. You should find an accountant in the UK who specializes in SME tax to review your DLA quarterly.
The Don’ts
Don't Treat the Business Bank Account as a Personal ATM: Frequent small withdrawals for personal items make the DLA messy and hard to reconcile.
Don't Ignore the £10,000 Limit: Even a single day above this limit triggers the BIK reporting requirements.
Don't Forget the S455 Deadline: Missing the 9-month repayment window is an expensive mistake that effectively locks away 35.75% of the loan amount with HMRC.
How an Accountant Keeps You Compliant
Managing a Director’s Loan Account isn't just about data entry; it’s about strategy. A professional accountant will look at your DLA alongside your salary and dividend strategy to ensure you are taking money out of the business in the most tax-efficient way possible.
They can help you:
Reclassify Withdrawals: Often, what looks like an overdrawn DLA can be legally reclassified as a dividend or salary (if profit and payroll allow), saving you from S455 risks.
Manage the 9-Month Deadline: They will alert you well in advance of your year-end if you need to make a repayment.
Handle P11D Filings: If you do cross the £10,000 threshold, they will ensure the reporting is accurate and submitted on time to avoid penalties.
