Director Loan Accounts and Section 455 Tax: A Complete Guide

The director's loan account (DLA) is one of the most flexible — and frequently mismanaged — tools available to owner-managed company directors. Used well, it provides short-term access to company funds without triggering immediate income tax or National Insurance. Used carelessly, it produces a substantial temporary corporation tax charge, a taxable employee benefit, and the potential for scrutiny from HMRC. This guide explains the mechanics, the pitfalls, and the planning considerations.

What Is a Director's Loan Account?

A director's loan account is a ledger entry in the company's books that tracks money owed between the director and the company. The balance can run in either direction:

Credit balance (company owes director): this arises when a director has lent money to the company, paid business expenses personally, or not yet drawn salary or dividends to which they are entitled. A credit balance carries no tax consequences — the director can draw down that balance at any time without any tax charge, because they are simply repaying money the company owes them.

Debit balance (director owes company): this is the situation that attracts tax consequences. The director has taken money from the company — typically as drawings — in excess of the amounts due via salary or dividends. This is an "overdrawn" DLA and is treated as a loan from the company to the director.

Section 455: The Temporary Corporation Tax Charge

When a director's loan account is overdrawn at the end of the company's accounting period, and the balance remains outstanding nine months and one day after the year-end, the company must pay a section 455 charge under the Corporation Tax Act 2010.

The section 455 rate mirrors the higher-rate dividend tax rate. For loans made before 6 April 2026, the rate is 33.75%. For loans made on or after 6 April 2026, the rate increases to 35.75%, following the rise in the dividend upper rate from that date. The higher rate does not apply retrospectively to loans already outstanding at 5 April 2026. Because HMRC treats an overdrawn DLA as broadly equivalent to an undeclared dividend, the rate tracks dividend tax changes automatically.

Example: a company has a 31 December year-end. At 31 December 2025, the director's loan account shows an overdrawn balance of £40,000. If that balance is not repaid by 30 September 2026 (nine months and one day after the year-end), the company must pay section 455 tax of £13,500 (33.75% × £40,000, as the loan predates 6 April 2026) on its corporation tax return. A loan first advanced in the accounting year ending 31 December 2026 would be subject to the 35.75% rate.

The charge is due at the same time as the company's corporation tax liability — nine months and one day after the year-end. There is no interest charged on the section 455 amount itself (though interest on the underlying loan may apply; see below), and the tax is added to the company's corporation tax account.

Repayment and Reclaim

The section 455 charge is not a permanent tax. If and when the director repays the loan — or the company waives it (see below) — the company can reclaim the tax from HMRC. The repayment is made nine months and one day after the end of the accounting period in which the loan is repaid.

This timing mismatch is important to understand. If the company paid section 455 tax in, say, October 2026 in respect of a loan outstanding at 31 December 2025, and the director then repays the loan in February 2027 (within the new accounting period ending 31 December 2027), the company cannot reclaim that tax until October 2028. That is a significant cash flow impact over a potentially two-year period.

Section 455 is therefore best understood as a timing mechanism — HMRC's way of collecting a deposit on what might become a tax-free extraction — rather than a permanent cost. The incentive is to repay loans promptly to avoid the charge arising at all.

Bed-and-Breakfasting: The Anti-Avoidance Rule

Predictably, many directors attempted to game the repayment rule by repaying their DLA just before the nine-month deadline, triggering a right to reclaim section 455 tax, then re-borrowing from the company shortly afterwards. HMRC introduced anti-avoidance legislation to counter this.

Under the "bed-and-breakfasting" rules, where:

• A loan of £15,000 or more is repaid, AND
• The same or a connected person takes a new loan from the company within 30 days of the repayment

The repayment is matched against the new loan. In effect, the repayment is treated as having been applied to the new loan, not the old one — so the old loan is deemed to continue and section 455 is still chargeable. The rule applies to arrangements that are essentially the same loan continuing, not to genuinely independent transactions.

For smaller loans under £15,000, the 30-day rule does not apply — but HMRC may challenge any arrangement that appears to lack commercial substance. The principle is that a genuine repayment followed by a genuinely separate new advance is acceptable; rapid cycling of large sums through the DLA to avoid section 455 is not.

The Beneficial Loan Charge

An overdrawn director's loan account is also a "beneficial loan" for employment income tax purposes, because the director is effectively borrowing from the company interest-free (or at a rate below the HMRC official rate). This gives rise to a taxable employment benefit under ITEPA 2003.

The taxable benefit is calculated as interest at the HMRC official rate on the average outstanding balance of the loan during the tax year. The official rate of interest was 3.75% for 2025/26; check HMRC's published rates for the current figure, as the rate is reviewed and may change during a tax year.

Example (using 2025/26 official rate of 3.75%): an overdrawn DLA averages £60,000 over the tax year. If the director charges no interest, the taxable benefit is £60,000 × 3.75% = £2,250. If the director is a higher-rate taxpayer, the income tax on this benefit is £900 per year. The company also pays Class 1A National Insurance on the benefit at 15% (the rate applying from 6 April 2025), adding a further £338.

This benefit must be reported on form P11D and included in the director's self-assessment tax return. It is worth noting that the benefit charge applies even where section 455 tax has been paid — the two charges are entirely separate: one is a company-level charge on the outstanding principal; the other is a personal income tax charge on the notional interest.

Directors who choose to charge interest on their DLA at the official rate — or above — avoid the benefit-in-kind charge entirely. The interest must be actually paid to the company, which then includes it as taxable income.

Waiver and Write-Off

If the company writes off the director's DLA — formally waiving the debt — the amount waived is treated as a distribution (dividend) to the director, taxable under ITTOIA 2005. There is no National Insurance charge on a waiver, but income tax at dividend rates applies. Section 455 tax paid by the company on the waived amount becomes repayable to the company.

This is occasionally used as a deliberate planning step, but it should be approached carefully: a write-off is the company permanently giving up a debt, which may require shareholder approval, and the tax cost (dividend rates up to 39.35%) is often higher than structured repayment.

Practical Planning: Managing Your DLA Efficiently

Year-end monitoring: the critical date is the accounting year-end, not the date of repayment. Monitoring your DLA balance as the year-end approaches — and making repayments or voting a dividend before year-end if the balance is likely to be high — is the simplest way to avoid section 455.

Dividend vs DLA: if you have been drawing funds throughout the year via the DLA, declaring a dividend before the year-end that matches or exceeds the debit balance brings the account back to zero. The dividend is taxable, but the overall position is cleaner: no section 455, no beneficial loan charge.

Timing salary and dividends: a director who is in the basic-rate band may prefer to draw funds during the year via the DLA and then clear it with a low-rate dividend at year-end, rather than taking a salary that would attract National Insurance on both employer and employee sides.

Multiple accounting periods: if your loan spans more than one accounting period, section 455 is charged on the balance outstanding at each year-end separately. Keep detailed records of the opening balance, drawings, and repayments in each period.

Leaving the UK: if you are relocating overseas and plan to remain as a director of your UK company, overdrawn DLAs become more complex. HMRC may treat repayment as arising from a non-UK source in some circumstances, and the interaction with your residence position needs careful consideration.

All section 455 rates and official loan interest rates are subject to change and should be verified before making decisions. Specific advice from a qualified tax adviser is recommended for anything beyond straightforward DLA management.
