Credit DLA — mechanics, repayment and interest
A credit DLA arises when the director has lent money to the company (injected capital; paid company expenses from personal funds; declared but undrawn dividends). Repayment of a credit DLA is tax-free — it is the return of the director's own capital. The director can charge interest at a commercial rate: deductible from the company's corporation tax; income tax for the director (savings income; personal savings allowance applies). Companies Act 2006 s.413 requires disclosure of director loans above £15,000 in the company's annual accounts.
Overdrawn DLA and the section 455 tax charge
An overdrawn DLA arises when the director draws more from the company than entitled to in salary and declared dividends. At year end, if overdrawn and not cleared: s.455 CTA 2010 charge at 33.75% of the overdrawn balance — payable within 9 months and 1 day of the accounting year end. The 9-month window allows directors to clear the DLA before the CT600 due date (repay cash to company; or formally declare a dividend equal to the balance if sufficient distributable reserves exist).
Benefit in kind if overdrawn DLA exceeds £10,000
If the overdrawn DLA exceeds £10,000 at any point during the tax year, a benefit in kind arises (ITEPA 2003 ss.173-183). Calculated at HMRC's official rate (3.25% 2025/26) on the average overdrawn balance. Reported on P11D (due 6 July); director pays income tax at marginal rate; company pays Class 1A NICs at 13.8%. Eliminated if the director pays interest on the overdrawn DLA at or above the official rate.
30-day anti-avoidance rule and section 458 repayment relief
30-day bed and breakfast rule (s.464A CTA 2010): repaying £5,000+ within 30 days of the s.455 due date and re-drawing the same within 30 days means the repayment is ignored — the s.455 charge still applies. Section 458 CTA 2010 relief: when the director genuinely repays the overdrawn DLA, the s.455 tax is reclaimed from HMRC — 9 months and 1 day after the end of the accounting period in which the repayment occurs. Writing off the DLA is NOT recommended — treated as employment income for the director (income tax + PAYE/NIC; not dividend treatment).
