Tax Implications of an Overdrawn DLA

Section 455 Tax (Corporation Tax Act 2010)

FeatureDetail
When it appliesDLA is overdrawn at your company’s year-end and not repaid within 9 months and 1 day
Tax rate33.75% of the outstanding balance (aligned with higher-rate dividend tax)
Who pays itThe company (not you personally)
When it’s paidWith the corporation tax payment (9 months and 1 day after year-end)
Refundable?Yes — refunded when the loan is repaid (but not until 9 months after the end of the accounting period in which it’s repaid)
ExampleYou owe the company £10,000 at year-end → company pays £3,375 S455 tax → you repay the £10,000 → company gets the £3,375 back (eventually)

Benefit-in-Kind (BIK) Tax

FeatureDetail
When it appliesDLA is overdrawn by more than £10,000 at any point during the tax year
WhyHMRC treats the loan as a taxable benefit (interest-free borrowing)
How it’s calculatedOutstanding balance × HMRC official interest rate (currently 2.25%)
Example£20,000 overdrawn for the full year → BIK = £20,000 × 2.25% = £450
Your taxIncome tax on the BIK amount (at your marginal rate)
Company’s costClass 1A NI at 13.8% on the BIK amount
How to avoid itPay interest to the company at the official rate (currently 2.25%)
ReportingReported on form P11D

If the Loan Is Written Off

FeatureDetail
Tax treatmentTreated as employment income — subject to income tax and NI
NI costBoth employee NI and employer NI apply
For a shareholder (not employee)Treated as a distribution — taxed at dividend rates
S455 refund?Yes — company gets S455 tax back when the loan is written off

Bed and Breakfasting Rules

FeatureDetail
What is itRepaying a DLA before year-end and then re-borrowing shortly after to avoid S455
HMRC’s anti-avoidance ruleIf you repay £5,000+ and re-borrow £5,000+ within 30 days, HMRC treats the loan as never having been repaid
ExampleYou owe £20,000. You repay £15,000 on 28 March. You borrow £15,000 on 10 April. HMRC treats the original £20,000 as still outstanding
Also applies toRepayments matched against new loans of £15,000+ made within the same accounting period or within 30 days before/after
How to avoidDon’t repay and re-borrow within 30 days. If you need to borrow again, wait at least 30 days
