Director's Loan Account: Section 455 Tax Explained

If you own a UK limited company, your director's loan account (DLA) is the single most-misunderstood item on your balance sheet. Get it wrong and you accidentally hand HMRC 33.75% of the overdrawn balance as a Section 455 tax charge — refundable, eventually, but a real cash cost in the meantime. This is the practical guide every owner-managed company needs.

What is a director's loan account, really

The director's loan account is a notional running balance in the company's books that tracks net amounts owed between the director (as an individual) and the company (as a separate legal entity). Despite the name, it's not a single loan — it's an account that gets credited and debited continuously.

The DLA gets credited (company owes you) when:

• You pay company expenses on your personal credit card
• Company declares a dividend or bonus before paying it
• You lend the company money for cash flow
• Salary or expenses are accrued but not yet paid

The DLA gets debited (you owe the company) when:

• You take a cash withdrawal that isn't salary or formally-declared dividend
• The company pays a personal expense of yours (your tax bill, your mortgage, your kids' school fees)
• You overdraw beyond the cumulative credit balance

An overdrawn DLA (i.e. you owe the company) is where Section 455 tax kicks in. A credit DLA (company owes you) does not trigger Section 455 — but does need to be properly evidenced if you want HMRC to accept the corresponding loan repayments as non-taxable.

Section 455 tax — the 33.75% trap

Under Corporation Tax Act 2010 Section 455, when a close company (broadly: under 5 shareholders, owner-managed) makes a loan to a participator that remains outstanding for more than 9 months after the company's year end, the company pays a tax charge equal to 33.75% of the outstanding loan.

The 33.75% rate matches the higher-rate dividend rate. Why? To stop owner-directors from substituting "loans" (which don't trigger personal income tax) for dividends (which do). HMRC wants the same tax outcome either way.

Section 455 is refundable: when the director repays the loan, the company can reclaim the 33.75% back from HMRC. But:

• The reclaim is processed via the next CT600 return, not as an immediate cash refund
• You typically wait 12–18 months from repayment to actually receive the cash
• The cash sits with HMRC interest-free during that time

The 9-month rule and how to actually use it

Section 455 only bites if the loan is outstanding 9 months after the period end. So in theory, you can have an overdrawn DLA throughout the year without triggering S455 — provided you clear it within 9 months of year-end.

Year end 31 March 2026 → loan must be cleared by 1 January 2027 to avoid S455. Year end 31 December 2025 → loan must be cleared by 1 October 2026.

The clearing methods that work:

1. Repay it — director writes a personal cheque to the company. Cleanest, no tax implications, but requires actual cash.
2. Declare a dividend equal to the overdraft. The dividend hits the DLA as a credit, clearing the balance. Triggers personal income tax for the director (8.75%/33.75%/39.35% depending on band) but no Section 455.
3. Pay a bonus equal to the overdraft. Same effect as dividend, but more expensive: PAYE income tax (up to 45%) plus 8% employee NIC plus 15% employer NIC (the employer rate since 6 April 2025: gov.uk, Rates and thresholds for employers). Rarely the right choice unless you've already exhausted dividend optimisation.

The bed-and-breakfast rule (anti-avoidance since 2013)

The "obvious" workaround — repay the loan on 31 December 2026 (clearing it before the 1 January 2027 deadline), then redraw it on 2 January 2027 — was killed by the Finance Act 2013. Two specific anti-avoidance rules apply:

• The 30-day rule: If within 30 days before or after a loan repayment, the director takes a new loan of £5,000 or more, HMRC treats the repayment as not having happened. Section 455 still applies as if the loan was never cleared.
• The "arrangements" rule: Even outside the 30-day window, if the loan exceeded £15,000 at any point and there were "arrangements" in place to redraw funds, HMRC can ignore the repayment.

"Arrangements" is broadly interpreted. A regular pattern of clearing the DLA at year-end then redrawing within a couple of months is enough to trigger the second rule even if technically outside 30 days. The defence is hard contemporaneous evidence that the redraw was an unforeseen new transaction.

Benefit in kind on overdrawn DLAs

Separate from Section 455, an overdrawn DLA of more than £10,000 at any point in the tax year creates a Benefit in Kind (BiK) for the director — unless interest is charged at or above HMRC's official rate (currently 2.25% for 2024/25, reviewed quarterly).

If the loan is interest-free:

• The deemed BiK is the official rate × average loan balance for the tax year
• The BiK is reported on form P11D
• The director pays income tax on it at their marginal rate (20%/40%/45%)
• The company pays Class 1A NIC at 15% (the rate since 6 April 2025)

For an average overdrawn DLA of £25,000 in 2024/25 at 2.25% official rate: BiK = £562.50. Director income tax (40% bracket) = £225. Company Class 1A NIC = £77.62. Total cost: ~£302 — small in absolute terms but easily missed by accountants who only review the year-end balance, not the intra-year averages.

Dividend vs loan: which is cheaper?

For an owner-director who needs £40,000 of personal cash from the company, the three routes compare like this (assuming higher-rate taxpayer, FY2025/26 rates, £4,000 of dividend allowance already used):

The right answer for almost every owner-director: declare dividends to cover regular cash needs, use the DLA only as a short-term timing tool (e.g. bridge from January to March waiting for the dividend in the new tax year).

Worked example — £40,000 overdrawn DLA

Director Alex takes a £40,000 loan from his company on 1 May 2025 for a kitchen renovation. The company's year end is 31 March 2026. Alex has 9 months from 31 March 2026 — i.e. until 1 January 2027 — to clear the loan and avoid Section 455.

Scenario 1: Alex clears the loan via dividend declared 15 December 2026.

• Company declares £40,000 dividend (all to Alex)
• The dividend credits the DLA, clearing the £40,000 debit
• Section 455 not triggered (loan cleared within 9 months)
• Personal income tax: £40,000 × 33.75% = £13,500 (assuming higher-rate band)
• BiK during the loan period (8 months at avg £40K, 2.25%): ~£600 BiK → £240 income tax → ~£83 Class 1A NIC
• Total cost: ~£13,823

Scenario 2: Alex does nothing. Section 455 triggers.

• Section 455 tax due 1 January 2027: £40,000 × 33.75% = £13,500
• BiK ongoing while loan outstanding
• Eventually Alex repays the loan (say, 1 May 2027)
• S455 refund processed in next CT600 — cash received ~July 2028
• Alex still needs to extract the £40,000 personally — most likely dividend, costing another £13,500
• Total cost: ~£13,500 dividend tax + 18 months of interest-free loan to HMRC of £13,500

Scenario 2 is rarely chosen deliberately. It happens when the bookkeeping isn't visible to the director, the accountant doesn't flag it until after year-end, and the 9-month window slips by without action. Visible monthly management accounts catch this.

Why the DLA belongs on the monthly pack

The DLA balance should be on every monthly management pack alongside cash and creditors. If you only see your DLA at year-end when your accountant prepares the statutory accounts, you've lost six to nine months of optimisation runway. Our monthly bookkeeping and management accounts (from £295/month) show the DLA running balance every month, so the dividend-versus-loan decision can be made and the clearance dividend declared before the 9-month window closes.
