Borrowing from your own company seems simple enough on the surface. But a Director’s Loan comes with rules that can catch founders off guard – repayment deadlines, tax charges and investor implications that tend to surface at exactly the wrong moment.

Here’s what you actually need to know.

What is a Director’s Loan Account?

A Director’s Loan Account isn’t a bank account – it’s an accounting record. It tracks any money moving between you (the director) and your company that isn’t classified as salary, dividends or a regular business expense.

The account is in debit when the director owes money to the company, and in credit when the company owes money to the director. Simple enough in principle – but the tax treatment is where it gets more involved.

What are Director’s Loans commonly used for?

Director’s Loans typically come into play in one of two ways.

Scenario 1: Lending money to your company

You’re running an early-stage agency. You inject personal funds into the business to cover a laptop, domain registration and a website. No shares changed hands and you plan to get that money back – that’s a Director’s Loan. You can charge your company interest on it, which gets recorded as a business expense in your profit and loss statement. When you’re eventually repaid, the interest portion goes on your Self Assessment tax return.

Scenario 2: Borrowing money from your company

Revenue is coming in and you need to cover a personal expense – a car replacement, an unexpected bill. If you draw more than your declared salary or dividends, you’ve stepped into Director’s Loan territory. Before you do, check your startup’s ability to lend and get across the tax implications.

Three things to know straight away:

• Loans of £10,000 or more must be declared on your Self Assessment tax return and treated as a benefit in kind
• If the loan is interest-free or below HMRC’s Official Rate, you may be taxed on the difference
• For loans of £10,000 or more, shareholder approval and a formal loan agreement are strongly recommended

Director’s Loans and your investors

An overdrawn Director’s Loan Account creates real friction when investors are reviewing your financials – and it’s worth understanding why before you get to that conversation.

Protecting their investment: Investors want to know their capital is going into the business, not servicing a personal debt. Most will want any outstanding director’s loan repaid – or ring-fenced – before they commit. Their accountants will find it during due diligence, so it’s better to address it proactively.

Trust and perception: A large, lingering Director’s Loan can suggest a blurring of personal and business finances. That’s a trust issue – and trust is foundational when you’re raising from VCs, angels or a bank. Heading into a raise with your Director’s Loan Account at zero (or in credit) is simply good housekeeping.

Tax and interest: what you need to know

HMRC sets an Official Rate of Interest for Director’s Loans each year – you can check the current figure directly on HMRC’s website. If the interest on your loan falls below that rate, HMRC treats the difference as a benefit in kind. As a director, you’d be taxed on that shortfall – and your company would be liable for Class 1A National Insurance at 15% on the full value of the loan.

If the loan isn’t repaid within nine months and one day of your company’s accounting year-end, the company gets charged S455 tax at 33.75% of the outstanding amount. That’s a significant hit – and one that’s entirely avoidable with the right planning.

Repaying a loan – and what happens if you’re late

If you’ve been charged S455 tax and subsequently repay the loan, you can reclaim it – but only nine months after the end of the accounting period in which the debt was cleared. The process is slow and the admin is fiddly, so avoiding the situation is always the smarter move.

One practical option: defer your corporation tax payment until the Director’s Loan is cleared. Since the corporation tax deadline falls nine months after your financial year-end, this can give you a useful window to work within.

One more rule that catches founders out: you must wait a minimum of 30 days between repaying one Director’s Loan and taking out another. HMRC is well aware of the practice of repaying just before the nine-month deadline and immediately borrowing again – the rules exist specifically to prevent it.

The accidental Director’s Loan

It’s more common than most founders expect, and it usually happens through an incorrectly declared dividend.

✔️ Danielle has had a strong year. Before drawing anything out, she checks her company’s distributable reserves and speaks to her accountant. Everything’s above board – she takes her dividend and heads off to the Scottish Highlands, completely stress-free.

❌ Damien sees money in the business account and draws dividends from a loss-making company without checking the books. He’s just given himself an unintentional Director’s Loan – and HMRC isn’t far behind. Profits first. Dividends later.

The key rules, summarised

You’ve seen all of this in detail above, but here’s a clean reference you can come back to:

• Exhaust your other financing options before reaching for a Director’s Loan
• Repay within nine months and one day of your company’s year-end to avoid S455 tax at 33.75%
• Keep borrowings below £10,000 where possible – anything above must be declared and treated as a benefit in kind
• Wait at least 30 days between separate loans
• Never draw dividends without first confirming there’s distributable profit on the books
• Keep your Director’s Loan Account clear – or in credit – before any investor conversations
