04 Feb Section 455 Tax Rate Explained in Under 3 Minutes
If you're a limited company director, you've probably dipped into your Director's Loan Account (DLA) at some point. Maybe you needed to cover a personal expense, or perhaps cash flow was tight one month. It happens.
But here's the thing: leave that loan unpaid for too long, and HMRC comes knocking with something called the Section 455 tax rate. And trust me, it's not cheap.
Let's break down exactly what Section 455 is, how much it costs, and, most importantly, how to avoid getting stung by it.
What Exactly Is Section 455 Tax?
Section 455 is a tax charge on overdrawn Director's Loan Accounts that haven't been repaid within a specific timeframe.
Here's the setup: as a director, you can borrow money from your own company. Nothing dodgy about that. But if you don't pay it back quickly enough, HMRC sees it as a way to extract money from your business without paying the proper tax (like you would on salary or dividends).
So they invented Section 455 tax to discourage this. Think of it as HMRC's way of saying, "If you're going to use your company as a personal piggy bank, there's a price to pay."
The tax applies to what are called close companies, which basically means any limited company controlled by five or fewer shareholders. In other words, most small businesses in the UK.
The Section 455 Tax Rate: 33.75%
Let's get straight to the number that matters.
The current Section 455 tax rate is 33.75%.
That's not a small chunk of change. If your Director's Loan Account is overdrawn by £10,000 and you haven't repaid it in time, your company owes HMRC £3,375 in Section 455 tax.
For a £20,000 loan? That's £6,750.
You can see how this adds up fast. And here's the kicker: this tax is paid by your company, not you personally. So even though it's your loan, it's your business that takes the financial hit.
The rate mirrors the higher rate of dividend tax, which makes sense when you think about HMRC's logic. They're trying to prevent directors from dodging dividend tax by just "borrowing" money indefinitely.
When Does Section 455 Tax Get Triggered?
The deadline is 9 months and 1 day after your company's accounting year-end.
Let's say your company's financial year ends on 31st March 2026. You'd need to repay any overdrawn Director's Loan by 1st January 2027 to avoid the Section 455 charge.
Miss that deadline by even a single day, and the tax applies to the full outstanding balance.
Here's how it typically plays out:
- You take a director's loan during the year (let's say £15,000)
- Your company year-end is 31st March 2026
- The 9-month countdown starts from 1st April 2026
- Deadline to repay: 1st January 2027
- If the loan is still outstanding on 2nd January 2027, Section 455 tax kicks in
The tax is paid alongside your Corporation Tax return (CT600), so it's due at the same time as your main Corporation Tax bill, usually 9 months and 1 day after your year-end.
How to Get the Tax Back (Yes, You Can)
Here's the good news: Section 455 tax isn't gone forever.
If you repay the loan later, HMRC will refund the tax. But: and this is important: you can't get it back immediately.
You have to wait another 9 months and 1 day after the end of the accounting period in which you repaid the loan. Then you can claim the refund.
For example:
- You repay the £15,000 loan on 15th June 2027
- Your next company year-end is 31st March 2028
- You can claim the Section 455 refund from 1st January 2029
So even though you eventually get the money back, your company is essentially lending £5,062.50 (33.75% of £15,000) to HMRC for over a year. That's money that could have been used in your business, paid to suppliers, or invested in growth.
Also worth noting: you've got up to 4 years from the end of the accounting period when you made the repayment to claim the refund. Don't leave it too long.
Why Section 455 Matters for Your Cash Flow
Even if you plan to repay the loan eventually, the Section 455 tax can seriously mess with your cash flow.
Imagine this scenario:
You've borrowed £12,000 from your company for a house deposit. Life gets busy, the repayment deadline passes, and suddenly your company owes HMRC £4,050 in Section 455 tax.
That's cash your business might not have lying around: especially if things are already tight. And remember, this is on top of your regular Corporation Tax bill.
Worse still, if you're trying to secure financing or apply for business support, an overdrawn Director's Loan Account can raise red flags. Lenders and investors don't love seeing directors treating their company accounts like personal current accounts.
And there's another trap to watch out for.
If your director's loan exceeds £10,000 at any point during the tax year, it becomes a benefit in kind. That means:
- You'll need to report it on your P11D form
- You'll pay personal tax on the "benefit" at the official rate of interest (currently 3.75%)
- Your company pays 15% Class 1A National Insurance on top
So not only is your company paying Section 455 tax, but you're also getting hit with additional personal tax charges. Ouch.
Common Mistakes Directors Make with Their DLA
Over the years working as a limited company accountant, I've seen plenty of directors trip up on their Director's Loan Accounts. Here are the classics:
1. Forgetting the deadline exists
Life gets busy. The 9-month countdown passes, and suddenly there's a nasty tax bill.
2. Confusing the DLA with personal money
Your company is a separate legal entity. Money in the business bank account isn't automatically "yours."
3. Not tracking loans properly
Without accurate records, it's easy to lose track of how much you owe and when repayment is due.
4. Repaying the loan, then borrowing again immediately
HMRC has rules to stop "bed and breakfasting": where you repay a loan just before the deadline, then borrow again shortly after. If you repay and borrow again within 30 days, HMRC can still charge Section 455 tax.
5. Ignoring the P11D benefit threshold
That £10,000 limit catches people out all the time.
