The Director's Loan Trap: How Taking Money Out of Your UK Company Can Trigger a 33.75% Tax Charge

When you own a UK limited company, it is tempting to treat the business bank account like your own. Money arrives from customers, and whenever you need cash you simply move some out to yourself. It feels natural — it is your company, after all. But UK tax law draws a hard line between you and your company, and crossing that line without care can trigger a Corporation Tax charge of 33.75% on the money you took out. This is the director's loan trap, and it catches more non-resident founders than almost any other rule.

What Actually Counts as a Director's Loan

A director's loan is any money you take out of your company that is not one of the following: a salary processed through payroll, a properly declared dividend, a repayment of money you previously lent the company, or a genuine business expense. If you transfer company funds to yourself for personal use, or pay a personal bill from the company account, that is a director's loan.

Every withdrawal and repayment is tracked in what is called your director's loan account. When you have taken out more than you have put in, the account is "overdrawn" — which simply means you owe the company money. That overdrawn balance is what HMRC cares about.

The 33.75% Charge: Section 455

Here is the rule that hurts. If your loan account is still overdrawn nine months after the end of your Corporation Tax accounting period, your company must pay tax under Section 455 of the Corporation Tax Act 2010. The rate is 33.75% of the outstanding balance, or 32.5% for loans made before 6 April 2022.

Consider a company with an accounting period ending 31 December 2025. Nine months later is 30 September 2026. If, on that date, you still owe the company £20,000, the company must pay £6,750 to HMRC — that is 33.75% of £20,000. Importantly, it is the company that pays this charge, not you personally, so it is a direct hit to the cash in the business.

The Good News: It Is Refundable, but Slowly

Section 455 is described as a temporary tax because the company can reclaim it once the loan is repaid, written off, or released. The problem is timing. You cannot reclaim the tax immediately. Under HMRC's rules, the relief is only due nine months and one day after the end of the accounting period in which the loan was repaid. In practice, this means the money can sit with HMRC for a long time before it comes back.

There is also a deadline on the refund itself: you must claim within four years, or the company loses the right to reclaim. The reclaim is made using form CT600A as part of the Company Tax Return, or separately using form L2P. So while the charge is recoverable, it is far from automatic and far from instant.

The Separate £10,000 Benefit-in-Kind Trap

There is a second, separate rule that often surprises directors. If you owe the company more than £10,000 at any point in the tax year, the loan is also treated as a "benefit in kind" — the same way a perk like a company car would be. The company must report it on a P11D and pay Class 1 National Insurance, and you must report it on a personal Self Assessment tax return.

The benefit is calculated using HMRC's official rate of interest, which is 3.75% for the 2025 to 2026 tax year and remains 3.75% from 6 April 2026. You can avoid this charge by paying the company interest at or above the official rate, but if you pay nothing, the unpaid interest becomes a taxable benefit on you personally.

Do Not Try the "Bed and Breakfasting" Trick

Some founders try to dodge Section 455 by repaying the loan just before the nine-month deadline and then taking the same money straight back out a few days later. HMRC anticipated this years ago. Under the anti-avoidance rules, if the loan was more than £5,000 and you take a new loan of £5,000 or more within 30 days of repaying, the repayment is effectively ignored and the charge still applies. Similar rules bite at the £15,000 level where repayment and re-borrowing are pre-arranged. Repaying on paper while re-borrowing in reality does not work.

How to Stay on the Right Side of the Rule

The cleanest approach is to keep personal and company money strictly separate and to take what you need through proper channels — a salary run through payroll, or dividends declared from genuine distributable profits with the correct paperwork. If you do end up with an overdrawn loan account, the simplest fix is to repay it in full before the nine-month deadline, whether through a cash injection, a declared dividend, or a bonus.

Keep accurate records throughout the year so you always know your loan account balance, rather than discovering an unexpected 33.75% charge when your accounts are prepared. For non-resident directors who never visit the UK and run everything remotely, this is easy to overlook — and expensive to get wrong.
