A director’s loan account — usually shortened to DLA — is one of those accounting concepts that sounds more complicated than it is, but gets expensive fast if you ignore it. At its core, it records the money moving between you personally and your limited company that doesn’t fall into any other category: not salary, not dividends, not legitimate expense reimbursements. Any other cash you take out, or put in, sits in the DLA.

Most company directors have one without realising it. You paid a personal bill from the company account. You borrowed a bit of cash ahead of your next dividend. You loaned the company money when it was getting started. All of that flows through the director’s loan account, and HMRC expects it to be tracked properly. The balance has to appear on your company’s balance sheet at the year end, and depending on whether it’s overdrawn or in credit, there can be tax consequences — for the company, for you personally, or both.

Here’s how it all works.

The DLA is essentially a running ledger. It captures every transaction between you and the company that sits outside the normal payroll and dividend process.

Common entries on the debit side (money the company is owed by you) include: cash withdrawals for personal use, personal purchases put through the company card or account, and expenses the company paid on your behalf that aren’t legitimate business costs. On the credit side (money the company owes you) you’d typically find: money you personally lent to the company, business expenses you paid from your own pocket and haven’t yet been reimbursed for, and any salary or dividends declared but not yet paid out.

At the end of your financial year, you either owe the company money (the account is overdrawn) or the company owes you money (the account is in credit). The balance must go on the balance sheet either way. If it’s overdrawn — meaning you’ve taken more out than you’ve put in — that’s where things need careful handling, because HMRC takes a close interest in loans from a company to its director-shareholders.

One practical point worth making: the DLA is not a bank account, and it isn’t a free way to draw cash from the company. It’s a record. Treating it as a flexible draw-down facility without understanding the tax rules attached is one of the more common mistakes we see.

If your DLA is overdrawn at the end of your company’s accounting period and you don’t clear it within nine months of that date, the company faces a tax charge under Section 455 of the Corporation Tax Act 2010.

As of 6 April 2025, the S455 rate increased to 35.75% of the outstanding loan balance (it was 33.75% for loans made before that date). So if you owe your company £20,000 and haven’t repaid it within the nine-month window, the company has to pay HMRC just over £7,150 on top of its normal Corporation Tax bill. That’s a significant cost for what most directors think of as a timing issue.

The good news is that S455 tax is technically temporary. Once you repay the loan, the company can reclaim it using the L2P process — but you can’t claim that relief until nine months and one day after the end of the accounting period in which the loan was repaid. In other words, if your company year ends 31 March 2026 and you repay in June 2026, you won’t see the refund until January 2028 at the earliest. The cash is tied up a long time.

The company reports the loan on form CT600A alongside its Corporation Tax return. This isn’t optional — if there’s an overdrawn DLA at the nine-month mark and it isn’t declared, that’s a compliance problem that tends to come out in an HMRC enquiry.

The S455 charge is the headline risk, but it isn’t the only one. If your loan exceeds £10,000 at any point during the tax year and you’re also a shareholder in the company, HMRC treats the loan as a benefit in kind. That means you’ll need to report it on a P11D and the company will owe Class 1A National Insurance on the benefit value.

The benefit is calculated based on the difference between what you’re paying in interest (if anything) and HMRC’s official rate of interest. If you’re paying nothing, or paying interest below that official rate, the difference is the taxable benefit. This applies even if the loan is repaid well before the nine-month window — the benefit calculation runs through the tax year, not just at year end.

Charging commercial interest on the loan avoids the benefit in kind treatment, but then the director receiving that interest needs to declare it as personal income on their Self Assessment return. There isn’t a way around the tax entirely; it’s more a question of which route is least costly given your overall position.

For loans above £10,000 where the director isn’t also a shareholder, shareholder approval is required before the loan can be made. That’s a Companies Act requirement, not just a tax rule — overlooking it creates a compliance issue that sits separately from any HMRC concern.

Most overdrawn DLAs get resolved in one of three ways: repayment, writing off, or declaring a dividend to clear the balance. Each has different tax consequences.

Repayment is straightforward — pay the money back and the company can eventually reclaim the S455 tax, subject to the timing delay. Writing off the loan means the company forgives the debt, but the written-off amount is then treated as employment income for the director and taxed accordingly through PAYE. Clearing the balance by declaring a dividend works if the company has sufficient distributable profits — but the dividend still needs to go through the normal dividend process and be taxed as dividend income on your Self Assessment.

What you can’t do is simply ignore it. If the company becomes insolvent, loans to directors don’t disappear — a liquidator has the power to pursue the outstanding balance and recover it. In serious cases where a director can’t repay, personal bankruptcy is a real outcome. That’s an extreme scenario, but it’s why we take DLA balances seriously with every company client, not just at year end.

We’d also flag the bed-and-breakfasting rules: HMRC has anti-avoidance provisions that prevent directors from repaying a loan just before the nine-month deadline and immediately re-drawing the same amount. If you repay £30,000 and take £28,000 back within 30 days, the repayment is ignored for S455 purposes to the extent of the re-draw.

The DLA is much easier to manage if it’s tracked throughout the year rather than reconciled in a panic before the year-end accounts are due. A few practical habits make a significant difference.

First, keep personal and company finances separate as far as possible. A dedicated business bank account and a company card used only for business spending reduces the number of entries that need to go through the DLA and makes the reconciliation cleaner.

Second, if you know you’re going to take money from the company for personal use, decide upfront whether it’s a dividend or a loan. Dividends require distributable profits and a formal process; loans have tax implications if they aren’t repaid. The DLA shouldn’t be a default category for anything that doesn’t fit elsewhere.

Third, review the balance before the nine-month deadline, not after. If the account is overdrawn, you have options — but only while there’s still time to act. Once the deadline passes, the S455 charge is already due.

If you’re using Xero, the director’s loan account balance is visible in your balance sheet at any point. We set up all our company clients so this is easy to check, and we’ll flag it proactively if we see it heading somewhere that needs attention rather than waiting for you to ask.
