Director Loan Account: 7 Mistakes You're Making with Your DLA (and How to Fix Them)

Running your own limited company gives you incredible freedom. You set the vision, close the deals, and build something entirely your own. But somewhere between paying suppliers and filing annual accounts, administrative chores tend to pile up.

If there is one accounting feature that consistently trips up founders, it is the Director Loan Account (DLA).

To many company directors, the DLA feels like a mysterious black box: or worse, a ticking time bomb that only reveals itself when the year-end accountant's bill lands. In reality, your DLA is simply a running ledger of every transaction between you and your company that isn't a salary, dividend, or genuine business expense.

When managed correctly, it is a routine administrative formality. When ignored, it can attract unexpected tax charges from HMRC. Let’s walk through the 7 most common DLA mistakes founders make, and more importantly, how to fix them before they cause unnecessary stress.

1. Treating the Company Bank Account Like Personal Pocket Money

It happens to the best of us. You are out for dinner, or ordering office supplies online, and you grab the nearest card: which happens to be the business debit card. Or perhaps you transfer £500 from the company account to your personal account to cover an unexpected vet bill.

In isolation, these little transactions feel harmless. But every time you pay for personal expenses out of company funds: or take cash drawings without an official payroll entry: you are technically borrowing money from your company. That money gets added directly to your DLA as an overdrawn balance.

The Fix: Keep your personal and business finances strictly separated. If you do accidentally use the company card for a personal latte or grocery trip, don't let it sit quietly in the ledger. Log it immediately as a director's loan or reimburse the company the very next day. Establishing a clean boundary is a complete no-brainer for keeping your books audit-ready.

2. Ignoring the 9-Month Rule and Triggering Section 455 Tax

If your DLA is overdrawn at your company's accounting year-end, you have a strict grace period to clear it. Under UK tax rules, if an overdrawn director's loan is not repaid within nine months and one day of the accounting period end, your company must pay Section 455 (s455) tax on the outstanding balance.

The common misconception is that s455 only applies to large sums. In truth, it applies to any overdrawn amount.

The Fix: Never let year-end sneak up on you. Track your DLA balance continuously so you know your exact position months before the deadline. If the account is overdrawn, you have three primary ways to clear it before the nine-month mark:

• Repay the loan in cash from your personal funds.

• Declare a formal dividend (if your company has sufficient retained profits).

• Vote a director's bonus (subject to PAYE and National Insurance).

3. Crossing the £10,000 Threshold Without Charging Interest

Did you know that as long as your total director's loan stays below £10,000 at all times during the tax year, HMRC generally does not treat it as a taxable benefit in kind (BIK)?

The trap opens up the moment your balance ticks over £10,000: even for a single day: without charging official interest. Once you cross that line, the loan becomes a taxable benefit. Your company must report it on a P11D form, the director pays income tax on the implied benefit, and the company is hit with Class 1A National Insurance contributions.

The Fix: If your business model requires larger temporary borrowings, formally document the loan and charge interest at HMRC's official rate. Better yet, set up automated threshold alerts in your accounting software so you are instantly notified before your balance creeps anywhere near that £10,000 ceiling.

4. Falling Into the "Bed-and-Breakfasting" Anti-Avoidance Trap

Some founders think they have outsmarted the system by executing a classic card trick: they repay their overdrawn DLA right before the nine-month s455 deadline, only to re-borrow almost the exact same amount a few days later.

HMRC is well aware of this window-dressing tactic, known as "bed-and-breakfasting."

Under strict anti-avoidance legislation, HMRC enforces the 30-day rule (where a repayment over £5,000 is followed by a new loan within 30 days) and broader arrangement rules. If caught, HMRC will simply ignore your year-end repayment, meaning the s455 tax charge sticks around anyway.

The Fix: Avoid artificial round-trips of cash. If you clear a loan, make it a genuine, permanent settlement using real profits or genuine personal income, rather than a revolving door of temporary transfers.

5. Relying on Year-End Scrambles Instead of Real-Time Tracking

Waiting until your accountant reviews your annual records to check your DLA is like driving down the motorway while looking exclusively in the rearview mirror. By the time you spot an overdrawn balance or an unrecorded expense, your options for fixing it are severely limited.

The Fix: Shift from an annual scramble to real-time financial oversight. Using modern bookkeeping tools designed specifically for UK founders means your running balance is always visible, accurate, and up to date. When you can see your trial balance, profit and loss, and corporation tax estimates in real time, administrative tasks transform from a stressful guessing game into an effortless formality.

6. Writing Off the Loan Without Checking Personal & Corporate Tax Impact

When a DLA gets too large to comfortably repay, some directors consider having the company formally write off the loan. It sounds like an easy escape hatch, but a write-off is not a tax-free gift.

If your company releases you from repaying a loan, HMRC treats that written-off amount as taxable income: specifically, as if you received a dividend. That means you may owe personal dividend tax on the written-off sum, and the company must still navigate corporation tax nuances.

The Fix: Always evaluate whether a formal dividend or salary adjustment is more tax-efficient than a write-off. Consult your accountant or review your profit reserves before making any permanent ledger adjustments.

7. Failing to Offset Dividends and Expenses Correctly

Many directors declare dividends throughout the year or pay out-of-pocket for business expenses (like software subscriptions or travel) using their personal cards. If these transactions aren't logged and matched correctly against the DLA ledger, your books become chaotic.

For instance, if you incur £300 in valid business expenses on your personal card, the company actually owes you money. If you don't record that reimbursement, your DLA calculations get completely skewed.

The Fix: Keep an immaculate audit trail. Every time you declare a dividend, ensure you generate an official dividend voucher and instantly reflect the offset in your DLA running balance. When expense claims and dividends flow seamlessly into your ledger, your numbers remain spotless.

Frequently Asked Questions

What is a Director's Loan Account (DLA)?

A Director's Loan Account is a digital ledger maintained within your company's bookkeeping system that records all money transactions between you (the director) and your company that are not classified as salary, dividends, or reimbursed business expenses.

Does an overdrawn DLA always incur tax?

Not immediately. If your DLA is overdrawn at the company's financial year-end, you have nine months and one day to clear the balance before Section 455 corporation tax applies. Additionally, if the loan stays under £10,000 throughout the tax year and carries official interest, it avoids benefit-in-kind charges.
