Overdrawn Director’s Loans Explained: What UK Company Directors Must Know

September 26, 2025

Introduction

If you’re a UK company director—especially of a small or family-run limited company—it’s common to dip into company funds or put your own cash in to keep things moving. Those ins and outs are tracked through a Director’s Loan Account (DLA). Managed well, a DLA is a tidy way to separate personal and company money. Managed poorly, it can trigger extra tax, penalties, and unwanted HMRC attention.

As a Scotland-based firm working with owner-managed businesses every day, A2Z Accounting Solutions has pulled together this plain-English guide to help you stay on the right side of the rules.

What is a Director’s Loan Account?

A director’s loan account is simply a running record of money you take from or pay into your company that isn’t: 

• salary,
• reimbursed expenses, or
• dividends

Think of it as a current account between you and the company. At any point it will show that you either owe the company (overdrawn DLA) or the company owes you (in credit). HMRC expects you to keep accurate records and reflect the balance in your annual accounts.

When do tax charges bite?

Two main UK tax rules for company directors regimes can apply to director’s loans:

1) Corporation Tax – “Section 455” charge (loans to participators)

If your DLA is overdrawn at the company year end and not repaid within 9 months and 1 day of that date, the company may have to pay a temporary Corporation Tax charge known as s455. The s455 rate is aligned to the dividend upper rate and is 33.75% on loans made on or after 6 April 2022. The charge is repayable by HMRC once the loan is cleared, but you’ll be out of pocket until then. Report overdrawn balances on the CT600A pages with your Company Tax Return.

2) Benefit-in-kind (P11D) – “Cheap or interest-free loans”

If at any time in the tax year your loan from the company exceeds £10,000 and you don’t pay at least HMRC’s official rate of interest, you can face a benefit-in-kind charge. The company reports it on form P11D, and Class 1A NIC may be due. The official rate is published by HMRC and can change—always check the current rate for the tax year in question.

Good to know:

If the company writes off (forgives) your loan, that can create an income tax charge on you personally (and NIC implications).

Repayment rules and anti-avoidance traps

HMRC is alive to “bed-and-breakfasting”—repaying a loan just before the 9-month deadline and then taking out a similar amount shortly after to avoid s455. Two mechanical rules can re-characterise repayments if you repay £5,000+ and borrow £5,000+ again within 30 days, or if you have arrangements in place to replace the cash. The practical effect: your repayment may be set against new loans first, leaving the old balance still exposed to s455. Plan carefully and document transactions.

Common risks and penalties

• Cash‑flow hit from s455: Even though reclaimable later, the 33.75% s455 charge locks up cash with HMRC until you clear the loan.
• Benefit‑in‑kind exposure: Exceeding £10,000 without charging adequate interest leads to a P11D benefit for you and Class 1A NIC for the company.
• Write‑off tax charges: Writing off a director’s loan can be taxed on you personally.
• Poor records: Inadequate DLA bookkeeping is a classic enquiry trigger.

How to manage a Director’s Loan Account (without headaches)

1. Keep the DLA tidy and up to date: Post every draw and repayment promptly, attach explanations (e.g., “temporary advance for supplier invoice”), and reconcile monthly. This protects you if HMRC asks questions.
2. Plan remuneration – don’t default to loans: A balanced mix of salary and dividends usually beats long‑term loans from a tax and cash‑flow angle. Use forecasts to decide when dividends are affordable (i.e., from distributable reserves) and when salary/NIC is more efficient.
3. Watch the 9‑month window: Note your year‑end and set reminders well before the 9 months + 1 day deadline. If you can’t clear the balance, consider whether a bonus or dividend (if profits allow) can legitimately reduce the loan—taking account of personal taxes and company cash.
4. Charge interest where needed: If your loan may exceed £10,000, consider paying interest at least at HMRC’s official rate to avoid a benefit‑in‑kind. Document the agreement and ensure the company actually pays the interest.
5. Avoid anti‑avoidance pitfalls: Steer clear of repaying and re‑borrowing around the deadline. If you need to repay, keep it repaid or take advice before any fresh drawings to ensure the 30‑day rules don’t bite.
6. Use CT600A and P11D correctly: Overdrawn at year end? CT600A with your Corporation Tax return. Cheap/interest‑free loan over £10,000? P11D and Class 1A NIC by 6 July/22 July deadlines.

Worked example (simplified)

• Company year end: 31 December 2025
• Overdrawn DLA at year end: £20,000
• Position on 30 September 2026 (9 months + 1 day): still £20,000 outstanding

The company owes s455 at 33.75% = £6,750 with its Corporation Tax. If you fully repay the £20,000 on 15 December 2026, the company can claim a refund of the £6,750 (via the Corporation Tax system) after that repayment date. Meanwhile, if at any point your loan topped £10,000 without adequate interest, expect a P11D benefit calculation for you and Class 1A NIC for the company.

Key takeaways for company directors

• Keep the DLA clean: record, reconcile, and review monthly.
• Avoid overdrawn DLAs lingering past the 9‑month point.
• If borrowing £10,000+, consider paying interest at the official rate.
• Use CT600A and P11D correctly—and on time.
• Don’t try to game the dates; the 30‑day rules can bite.

FAQs: Director’s Loans (UK)

Q: Is a director’s loan the same as my salary or dividends?

A: No. It’s separate. Salary is PAYE‑taxed, dividends are paid from profits, and loans must be repaid (or tax charges can arise).

Q: What happens if my DLA is overdrawn at year end?

A: If it isn’t cleared within 9 months and 1 day, the company may pay s455. This is reclaimable when you repay—but the cash is tied up in the meantime. Report via CT600A.

Q: Can I just repay and take it back out later?

A: Be careful. Repaying £5,000+ and then borrowing £5,000+ again within 30 days can trigger rules that ignore your “repayment” for s455 purposes. Get advice first.

Q: Do I pay tax if the loan is interest‑free?

A: If your total loan exceeds £10,000 at any point and you pay less than HMRC’s official rate, a benefit‑in‑kind may arise—reported on P11D, with Class 1A NIC too.

Q: What if the company writes off my loan?

A: A write‑off is usually treated as income for you, so a personal tax charge can apply (and NIC implications). Avoid write‑offs without tailored advice.

Q: Does it matter that my company is a “close company”?

A: Most small UK companies are “close companies” (broadly, controlled by five or fewer shareholders), which is exactly where the s455 rules bite on loans to participators (including many directors/shareholders).
