You've built a successful agency. Turnover is climbing, the team is growing, and you've got cash in the company account. It's tempting to dip into that money for personal use. A new kitchen. A holiday. A deposit on a flat. You take it as a director's loan, planning to sort it out later.
That "later" can cost you 33.75% of the loan amount. Upfront. In cash. Non-refundable in most practical senses.
That's the Section 455 tax charge on director's loans. And it catches more agency founders off guard than almost any other compliance trap.
Here's how it works, when it applies, and how to keep your director's loan account clean.
What Is a Director's Loan Account?
A director's loan account (DLA) is simply the record of money moving between you and your agency. It's not a separate bank account. It's a bookkeeping entry in your accounting software (Xero, QuickBooks, FreeAgent, whatever you use).
Every time you take money out of the company that isn't a salary, dividend, or expense reimbursement, it goes into your DLA as a debit. Every time you put money back in, or the company pays a dividend or salary to you, it goes in as a credit.
If your DLA is overdrawn at the year end, you owe the company money. And that's where Section 455 comes in.
What Is the Section 455 Tax Charge?
Section 455 of the Corporation Tax Act 2010 says that if a company makes a loan to a director (or to someone connected with a director, like a spouse or child), and that loan isn't repaid within 9 months of the company's year end, the company must pay a tax charge equal to 33.75% of the outstanding amount.
For the 2025/26 tax year, that rate matches the higher rate dividend tax band. It's designed to stop directors from extracting profits as tax-free loans instead of paying tax on dividends or salary.
Key point: The charge is on the company, not on you personally. But the company is writing a cheque to HMRC for 33.75% of the loan amount. That's cash out of your agency's account. Cash you could have used for growth, hiring, or equipment.
A Real Example
Let's say your digital agency has a 31 March year end. On 1 January 2025, you take a director's loan of £40,000 to put towards a house deposit. You haven't repaid it by 31 December 2025 (9 months after the year end).
Your agency must pay HMRC £13,500 (33.75% of £40,000) as a Section 455 charge. That's due with your corporation tax payment, normally 9 months and 1 day after the year end. So by 1 January 2026, HMRC expects that £13,500.
If you repay the loan later, the company can reclaim the charge. But the cash is gone in the meantime. And reclaiming isn't automatic, you have to submit a claim.
When Does Section 455 Apply?
Section 455 applies to any loan or advance made to:
- A director of the company
- A person connected with a director (spouse, civil partner, children, parents, siblings, and their spouses)
- Certain other participators in close companies (which most agencies are)
It applies regardless of whether the loan is documented. If you just transfer money from the company account to your personal account, that's a loan. If you use the company credit card for personal spending and don't repay it, that's a loan. If the company pays a personal bill on your behalf, that's a loan.
There are a few exceptions:
- Loans of £10,000 or less, where the director is also an employee and the loan is for a qualifying purpose (like a season ticket loan)
- Loans made in the ordinary course of the company's business (rarely applies to agencies)
- Loans that are fully repaid within 9 months of the year end
But the £10,000 exemption is narrow. Most director's loans in agencies are for personal spending, not employment-related purposes.
How to Avoid the Section 455 Charge
There are several ways to keep your DLA in the black. None of them are complicated, but they all require discipline.
1. Repay the Loan Before the 9-Month Deadline
This is the simplest solution. If you take a loan, repay it within 9 months of the year end. That means if your year end is 31 March, any loan taken during the year must be repaid by 31 December.
If you can't repay in cash, consider a formal dividend declaration (if you have retained profits) to clear the balance. But be careful, dividends must be paid from distributable profits, and you must follow the correct legal process.
Warning: Don't repay the loan just before year end and then immediately re-borrow it after. HMRC can treat that as a "bed and breakfasting" arrangement and still apply the charge. There needs to be genuine repayment with no pre-arranged re-borrowing.
2. Take Dividends Instead of Loans
If you have retained profits in the company, declare a dividend rather than taking a loan. Dividends are taxed at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate) depending on your total income. But you get the £500 dividend allowance first.
For most agency founders, a combination of salary (£12,570) and dividends is the most tax-efficient way to extract profits. Taking a loan instead of a dividend just creates a tax problem later.
We cover this in more detail in our guide on salary and dividends for agency founders.
3. Set Up a Formal Loan Agreement
If you need to borrow from the company for a genuine purpose (like a house deposit), put a formal loan agreement in place. The agreement should include:
- The loan amount
- A repayment schedule
- Interest at HMRC's official rate (currently 2.25% for 2025/26)
- A clear repayment date within 9 months of the year end
If you charge interest at the official rate or above, the loan is a "qualifying loan" and the Section 455 charge doesn't apply. But the interest you pay is taxable income for the company, and you must report it on your personal tax return.
This is a legitimate approach, but it requires proper documentation and ongoing compliance. Most agency founders find it simpler to just avoid loans altogether.
4. Use a Director's Loan Account Properly
Many agency founders don't realise that their DLA can go overdrawn unintentionally. Common causes include:
- Personal expenses paid through the company credit card
- Personal bills paid from the company account
- Directors' personal NI or tax liabilities paid by the company
- Assets transferred from the company to the director at below market value
Review your DLA quarterly. If it's overdrawn, clear it before the year end. Your accountant should flag this in your management accounts, but don't rely on that alone. Ask for a DLA balance at every quarterly review.
We work with marketing agencies, digital agencies, and creative agencies across the UK, and this is the single most common compliance issue we see.
5. Keep Accurate Records
Every transaction between you and the company must be recorded. If you use the company card for a business lunch, that's an expense. If you use it for a personal dinner, that's a loan. The difference matters.
Use accounting software that tracks director's loan accounts automatically. Xero and QuickBooks both have DLA functionality. FreeAgent is particularly good for this. If you're not using one of these, switch. Manual spreadsheets are a recipe for missed deadlines and unexpected charges.
What Happens If You Don't Repay?
If the loan remains outstanding beyond the 9-month window, the company must pay the Section 455 charge. That's 33.75% of the loan amount, due with the corporation tax payment.
The charge is shown on the CT600 corporation tax return. Your accountant will include it if they know about the loan. If they don't know (because you haven't told them), you're looking at a potential penalty for incorrect returns.
If the loan is later repaid, the company can reclaim the charge. But reclaiming requires a formal claim to HMRC, and the repayment is treated as a credit against the company's corporation tax liability. It's not a cash refund in most cases, it reduces the next tax bill.
Practical reality: Most agency founders who trigger a Section 455 charge don't repay the loan quickly. The cash is gone. The company pays 33.75% to HMRC. The loan sits on the books. And the charge becomes a permanent cost of extracting the money.
What About Loans to Other Directors or Shareholders?
Section 455 applies to loans to any participator in a close company. That includes shareholders who aren't directors. If you have a co-founder who takes a loan, the same rules apply.
If your agency has multiple directors, each director's DLA must be tracked separately. You can't net one director's overdrawn balance against another's credit balance. Each loan is assessed individually.
This is particularly relevant for recruitment agencies and advertising agencies where multiple founding directors often take loans at different times.
How HMRC Enforces Section 455
HMRC checks director's loan accounts as a matter of course during corporation tax compliance checks. If they see an overdrawn DLA, they'll ask for an explanation. If the loan isn't repaid within 9 months, they expect to see the Section 455 charge on the CT600.
If you don't report it, HMRC can:
- Raise a discovery assessment for the tax due
- Charge penalties for incorrect returns (up to 100% of the tax)
- Charge interest on the unpaid tax from the original due date
The penalties can be substantial. A £40,000 loan that should have triggered a £13,500 charge could end up costing £27,000 or more with penalties and interest.
If HMRC opens a compliance check and finds an unreported director's loan, they will also look at other areas of your tax affairs. It's not a conversation you want to have.
What to Do If You Already Have an Overdrawn DLA
If you're reading this and realising your DLA is overdrawn, here's what to do:
- Check the date. If you're still within 9 months of your year end, you can still repay the loan and avoid the charge.
- Calculate the balance. Work out exactly how much you owe the company. Include all personal transactions.
- Repay if possible. Transfer cash from your personal account to the company account. If you don't have the cash, consider a formal dividend declaration (if profits allow).
- Tell your accountant. If the loan is already beyond the 9-month window, your accountant needs to know so they can include the Section 455 charge on the CT600.
- Set up a repayment plan. If you can't repay in one go, agree a schedule with your accountant. The charge is already triggered, but repaying the loan allows you to reclaim it later.
If you're unsure about your current DLA position, speak to your accountant. If you don't have one who specialises in agencies, get in touch. As ICAEW qualified accountants, we deal with this regularly for agency founders across the UK.
Section 455 and Business Asset Disposal Relief
There's a specific interaction between director's loans and Business Asset Disposal Relief (BADR) that catches some agency founders at exit.
If you sell your agency shares and have an outstanding director's loan, the loan is treated as a distribution of profits. That means it's taxed as dividend income, not as capital gains. And it can affect your BADR claim.
If you're planning to sell your agency, clear your DLA before completion. Leaving it outstanding can create a tax bill at dividend rates (up to 39.35%) instead of the 14% BADR rate. That's a significant difference on a six-figure loan.
We cover this in more detail in our guide on agency exit planning.
Common Mistakes Agency Founders Make
Mistake 1: Thinking it's just a temporary loan. "I'll repay it next month." Six months later, it's still outstanding. Set a repayment date and stick to it.
Mistake 2: Not telling the accountant. Your accountant can't file an accurate CT600 if they don't know about the loan. HMRC will find it. The penalties are worse than the tax.
Mistake 3: Using the company card for everything. Mixing personal and business spending creates a mess. Use a separate personal card for personal spending. Full stop.
Mistake 4: Repaying just before year end and re-borrowing after. HMRC sees through this. If there's a pre-arranged re-borrowing, the charge still applies.
Mistake 5: Assuming dividends can clear any DLA balance. Dividends must be paid from distributable profits. If your agency hasn't made enough profit, you can't declare a dividend. The loan remains.
Final Thoughts
The Section 455 tax charge is a compliance trap, not a tax planning tool. It exists to stop directors from extracting profits tax-free. If you treat your director's loan account with the same discipline as your client retainer book, you'll never have a problem.
Review your DLA quarterly. Clear it before year end. If you need to extract cash, use salary and dividends in the right proportions. And if you're unsure, ask your accountant before you take the money, not after.
