Director's Loan Account: Avoid the Section 455 Tax Trap

A director's loan account records every transaction between you and your company that is not salary, dividends, or an expense reimbursement. It is a normal part of limited company accounting — but it comes with rules that carry significant tax consequences if you borrow from it and do not repay on time.

The key rule: if your loan account is overdrawn (you owe the company money) at your company's year-end and you have not repaid it within 9 months, HMRC charges the company 33.75% of the outstanding balance. That tax is repayable once the loan is cleared — but it is a real cash cost in the meantime, and most directors are not aware of it until they receive advice.

What is a director's loan account?

Every limited company maintains a director's loan account (DLA) — a running record of money flowing between the director and the company that isn't salary, dividends, or expenses. When you transfer money from the company to your personal account that isn't categorised as one of those three things, it's recorded as a director's loan. When you put personal money into the company, that's also recorded there.

A DLA can be in credit (the company owes you money — common if you've lent the company startup funds) or overdrawn (you owe the company money — where the tax risks sit).

The Section 455 charge explained

If your director's loan account is overdrawn at your company's financial year-end, and you haven't repaid it within 9 months and 1 day after that year-end, HMRC charges your company a Section 455 tax equal to 33.75% of the outstanding balance.

The good news: the S.455 charge is repayable by HMRC once you repay the loan to the company. The bad news: there's a further 9-month wait after repayment before HMRC refunds it. Cash flow can be tied up for 18 months or more.

The beneficial loan benefit in kind

If the total outstanding on your DLA exceeds £10,000 at any point during the tax year, HMRC treats the interest-free (or low-interest) use of that money as a benefit in kind. You'll owe income tax on the notional interest — calculated at HMRC's official rate (currently 2.25% per year). Your company also owes Class 1A National Insurance on the same benefit.

Example: £15,000 overdrawn for a full year at 2.25% = £337.50 taxable benefit. At 20% tax: ~£68 personal income tax, plus Class 1A NI for the company. Small but worth knowing — and easy to report if your accountant knows about the balance.

Common ways directors accidentally overdraw their DLA

• Transferring money to personal accounts "to cover expenses" without proper categorisation
• Paying personal bills from the company bank account
• Taking money before the dividend paperwork has been formally approved
• Paying for personal subscriptions, shopping, or car expenses via the company card
• Not reconciling the DLA regularly — small amounts accumulate without notice

Golden nugget: declare dividends formally before transferring money

Many directors transfer money to their personal account and decide later whether to classify it as salary or dividends. This is the single most common cause of an accidentally overdrawn DLA. Instead, hold a brief formal board meeting (even as the sole director, this is a written minute you sign), declare a specific dividend amount, and then transfer that exact amount. It takes five minutes, creates a paper trail, and keeps your DLA clean. Your accountant should have a standard dividend minute template.

How to clear an overdrawn DLA

If your DLA is overdrawn, you have several options before the 9-month deadline:

• Repay the loan in cash — transfer money back to the company from your personal account
• Declare a dividend — if the company has sufficient distributable profits, vote a dividend to offset the overdrawn balance
• Pay additional salary — but this incurs full PAYE income tax and NI, so it's usually the least efficient option
• Write off the loan — the company formally waives the debt, but this is then treated as a dividend (and taxed as one) with Class 1 NI implications

When a credit DLA is useful

If you've lent money to your company — for example, startup costs you personally funded — the DLA is in credit and the company owes you. You can repay yourself from company funds tax-free at any time, since you're just recovering your own loan. This is a legitimate and tax-efficient way to extract money — better than a dividend in some circumstances, because repaying a loan has no income tax consequences.
