Let’s be honest: when you’re running a limited company, the line between "my money" and "the company’s money" can start to look a little blurry. You’re the one doing the work, you’re the one taking the risks, and you’re the one at the helm. It’s tempting to treat that business bank account like an ATM with an infinite daily limit.
But here’s the cold, hard truth: HMRC is watching. And they aren't just glancing; they are looking for that one slip-up that turns a simple Director’s Loan into a tax nightmare.
At Makes Sense Accountants, we see it all the time. A director takes a few hundred here for a personal bill, a few thousand there for a holiday deposit, and suddenly, the "Director’s Loan Account" (DLA) is a tangled mess of transactions that looks more like a financial trap than a business record. If you don't have a handle on your limited company accounting services, you’re essentially walking through a minefield blindfolded.
The Invisible Scoreboard: What is a Director’s Loan Account?
Think of your Director’s Loan Account as a scoreboard. It tracks every penny that moves between you (the individual) and the company (the legal entity).
- If you put money in: The company owes you.
- If you take money out (that isn't salary or a dividend): You owe the company.
The moment that scoreboard shows you owe the company money, you’ve entered "overdrawn" territory. This is where the puzzles start and where HMRC begins to sharpen their pencils. Mixing personal and business cash is the fastest way to trigger a full-blown investigation. To HMRC, an overdrawn DLA is often seen as a sneaky way to avoid paying Income Tax or National Insurance.

Mistake #1: The Nine-Month "Cliff Edge"
This is the big one. It’s called the Section 455 tax charge, and it is a massive trap for the unwary.
If your company’s year-end passes and you still owe the company money, you have exactly nine months and one day to pay it back. If you don't? HMRC hits the company with a tax charge. As of April 2026, that charge is a staggering 35.75% of the outstanding loan amount.
Imagine borrowing £20,000 to cover some personal renovation work. If you don't clear that balance within the nine-month window, your company has to hand over an extra £7,150 to HMRC in corporation tax. Yes, you eventually get that money back once the loan is repaid, but the process is slow, tedious, and wreaks havoc on your business cash flow. This is where professional corporation tax services become vital, keeping you far away from that cliff edge.
Mistake #2: The £10,000 "Benefit in Kind" Trap
HMRC has a very specific rule about "cheap" loans. If you borrow more than £10,000 from your company at any point during the year and you aren't paying the "official rate" of interest (currently around 3.75%), HMRC considers this a "Benefit in Kind."
In their eyes, you’ve received a perk of the job that has a monetary value. You’ll have to report this on a P11D form, pay personal Income Tax on the "benefit," and the company will have to pay Class 1A National Insurance. It’s a classic example of a small oversight turning into a triple-taxation headache.
Are you keeping a daily log of your DLA balance? Probably not. But HMRC’s data-matching software is getting better every year, and they can spot these thresholds being crossed in a heartbeat.

Mistake #3: The "I’ll Fix It Later" Mentality
The most dangerous words in business are: "I'll just take a bit now and sort it at the end of the year."
When you treat your business account like a personal piggy bank without real-time bookkeeping, you lose track of the "true" profit of the business. You might think you have plenty of cash for a dividend, only to realize at year-end that the money you’ve already taken has wiped out your distributable profits.
This leads to "illegal dividends", taking money the company hasn't actually earned yet. When this happens, HMRC reclassifies those payments as salary, meaning you suddenly owe massive amounts of backdated PAYE and National Insurance. This is why we advocate for proactive bookkeeping and business services to ensure you always know where the line is drawn.
Mistake #4: Writing Off the Loan (The Double-Whammy)
Sometimes, a director decides they can’t or won't pay the loan back, so they decide to "write it off" in the company accounts. You might think, "Problem solved, the debt is gone."
Wrong.
Writing off a director's loan is like waving a red flag in front of a bull. HMRC treats a written-off loan as taxable income for the director. You’ll pay Income Tax on it, and the company usually doesn't get a tax deduction for the "loss." It is one of the most tax-inefficient ways to move money out of a company. It’s a trap that many fall into when they try to close a business without proper advice. If you're in this position, you need to look at how to close a limited company tax-efficiently before you make a move.
Mistake #5: Failing the "Paper Trail" Test
If HMRC decides to open a tax investigation, the first thing they’ll ask for is the paper trail for your DLA.
- Did you get shareholder approval for a loan over £10,000?
- Is there a written loan agreement?
- Are the minutes of the board meeting recorded?
If the answer is "no," HMRC can argue that the money wasn't a loan at all, but rather salary that you’ve tried to disguise to avoid tax. Without the right documentation, you are essentially defenseless. In the world of accounting, if it isn't written down, it didn't happen: or worse, it happened in the way that costs you the most money.
How to Stay Out of the HMRC Crosshairs
Avoiding these mistakes isn't just about being "good at math." It's about discipline and having the right systems in place. Here is how you keep your Director's Loan Account clean:
- Separate Everything: Use separate bank accounts and never, ever use the business card for the weekly grocery shop.
- Real-Time Tracking: Use cloud accounting software to see your DLA balance every single day. If it starts creeping toward £10,000, stop.
- Plan Your Withdrawals: Instead of "dipping in," set a monthly salary and schedule regular dividend payments based on actual profit.
- Watch the Calendar: Know your year-end date and your nine-month deadline like the back of your hand.
- Get Professional Eyes on the Books: A specialized ltd company accountant will spot an overdrawn DLA months before it becomes a tax disaster.
