Director's Loan Account Explained (and the S455 Tax Trap)

The director’s loan account is one of the most misunderstood — and most costly when mishandled — parts of running a limited company. Take a bit too much out, leave it too long, and HMRC has a tax charge waiting. Here’s how it works and how to stay clear of trouble.

What is a director’s loan account?

Your company is a separate legal entity, so its money isn’t automatically yours. A director’s loan account (DLA) tracks any money moving between you and the company that isn’t:

• Salary (through PAYE)
• Dividends (from profit)
• Expense reimbursements (for genuine business costs)

If you take money out beyond those, you owe the company — your DLA is “overdrawn.” If you put your own money in, the company owes you.

The S455 tax charge — the big trap

This is the one that catches directors out. If your DLA is overdrawn at your company’s year-end and you haven’t repaid it within 9 months and 1 day of that year-end, your company has to pay a temporary tax charge called S455 — currently 33.75% of the outstanding balance.

The good news: S455 is refundable once you repay the loan. The bad news: you don’t get it back until 9 months after the end of the year in which you repay — so it can tie up real cash for a long time.

The £10,000 benefit-in-kind rule

There’s a second catch. If your overdrawn loan goes above £10,000 at any point in the tax year, it’s treated as a benefit in kind — like an interest-free perk — unless you pay the company interest at HMRC’s official rate. That triggers:

• A P11D benefit charge on you personally, and
• Class 1A National Insurance for the company

So a large overdrawn loan can hit you with both S455 and a benefit-in-kind charge.

How to stay out of trouble

• Keep good records. The DLA only works if your bookkeeping is current and the balance is known — not discovered at year-end.
• Clear an overdrawn balance within 9 months and 1 day of year-end, by repaying it or declaring a dividend or bonus (if profits allow).
• Stay under £10,000 to avoid the benefit-in-kind charge.
• Avoid “bed and breakfasting” — repaying just before year-end and re-borrowing shortly after, which HMRC has specific rules to counter.

It’s not all bad

A director’s loan can be useful — short-term cash flow, or lending money to your company (where the company can pay you interest, sometimes tax-efficiently). The key is doing it deliberately and tracking it, not drifting into an overdrawn account by accident.

Keep it under control

The director’s loan account is exactly the kind of thing that’s invisible until it costs you — and then it costs you twice. Our limited company bookkeeping keeps your DLA monitored month to month, and our Accounts & Corporation Tax service and accountants for limited companies make sure it’s cleared efficiently before any charge bites. Pair it with the right salary and dividend plan and you’ll rarely need to worry about it.
