If you run a limited company and take money out that isn’t salary or dividends, you may trigger s455 tax without even realising it. Many directors treat the company bank account like a flexible wallet. That’s usually where problems start. HMRC sees unpaid director loans very differently and the tax charge can be significant.
In this guide we’ll break this down properly so you understand exactly when s455 tax applies, how much it costs, and how to avoid it.

What Is S455 Tax
S455 tax is a temporary corporation tax charge of 33.75% that applies when a close company lends money to a director or shareholder and the loan is not repaid within 9 months and 1 day after the accounting year end. The purpose of s455 tax is simple. It prevents directors from extracting company funds tax-free by disguising them as loans instead of dividends or salary. It is not a permanent tax. But it can seriously impact your company’s cash flow.
When Does S455 Tax Apply
S455 tax applies when three conditions are met:
- The company is a close company
- The money is lent to a participator (usually a director or shareholder)
- The loan remains outstanding after the deadline
Most owner-managed limited companies in the UK are classed as close companies.
If you withdraw funds that are not:
- Salary processed through PAYE
- Properly declared dividends
- Reimbursed business expenses
Then those withdrawals usually sit in your Director’s Loan Account. If that account becomes overdrawn and isn’t cleared in time, s455 tax becomes payable.
If you’re unsure how payroll differs from director withdrawals, our guide on What Is PAYE explains the difference clearly.
What Is A Director’s Loan Account
A Director’s Loan Account (DLA) is simply a record of money moving between you and your company. If you put money into the business, the company owes you. If you take money out that isn’t salary or dividends, you owe the company. When your DLA shows a negative balance at year end, that’s where s455 tax risk begins.
This is why proper small business bookkeeping matters. Poor bookkeeping is one of the most common reasons directors accidentally trigger s455 tax.
What Is The Current S455 Tax Rate
The current s455 tax rate is 33.75% of the outstanding loan balance. This rate aligns with the higher dividend tax rate and increased in April 2022.
Example
A director withdraws £30,000 during the year. The accounting year ends 31 March 2025. The loan is still unpaid by 1 January 2026 (9 months and 1 day later).
S455 tax due:
£30,000 × 33.75% = £10,125
The company must pay this amount to HMRC alongside its Corporation Tax.
When Is S455 Tax Due
The deadline for paying s455 tax is 9 months and 1 day after the end of the accounting period. This is the same deadline as Corporation Tax. Missing this deadline can create avoidable penalties and unnecessary cash flow pressure.
How Do You Avoid S455 Tax
The good news is that s455 tax is avoidable with proper planning.
Repay The Loan Before The Deadline
The cleanest solution is simply repaying the outstanding balance before the 9 month deadline. This completely removes the s455 charge.
Declare Dividends Properly
If your company has sufficient distributable profits, you can declare dividends and offset them against the loan.
But dividends must be legal and supported by:
- Profit reserves
- Board minutes
- Dividend vouchers

Process Salary Through PAYE
You can clear part of the loan by running additional salary through payroll. However, this triggers:
- Income tax
- National Insurance
It may not always be tax efficient.
What Is Bed And Breakfasting
Some directors try to repay the loan just before the deadline and then withdraw it again shortly after. HMRC introduced anti-avoidance rules to stop this.
If:
- £5,000 or more is repaid
- And similar amounts are reborrowed within 30 days
The repayment may be ignored for s455 purposes.
Is S455 Tax Refundable
Yes. S455 tax is refundable once the loan is repaid. However, the refund cannot be claimed immediately.
The company can reclaim it:
9 months after the end of the accounting period in which the loan was repaid. This means cash can be locked up for over a year. That’s why prevention is better than cure.
What Happens If The Loan Is Written Off
If the company writes off the loan:
- It becomes taxable income for the director
- Dividend tax may apply
- National Insurance considerations may arise
This can create a larger personal tax liability than expected.
If you’re already preparing income documentation such as an SA302 for mortgage purposes, director loan write-offs can complicate matters.
Does S455 Apply To All Companies
No. S455 tax only applies to close companies.
Most small and medium-sized limited companies in the UK fall into this category because they are controlled by:
- Five or fewer shareholders
- Or directors and shareholders combined
Public limited companies are generally excluded.
How S455 Works
A construction company director withdraws £60,000 over the year during a slow period. Profits are lower than expected, so dividends cannot be declared. The Director’s Loan Account remains overdrawn.
S455 tax liability:
£60,000 × 33.75% = £20,250
That’s £20,250 of company cash paid to HMRC temporarily but still painful.
If you’re in industries like construction, specialist tax planning becomes even more important.
How Is S455 Tax Reported
S455 tax is reported through:
- The Corporation Tax return (CT600)
- Additional supplementary pages
It cannot be ignored or hidden. HMRC cross-checks Director’s Loan Accounts during compliance reviews, particularly where companies show low salary and low dividends but high withdrawals.

FAQs
Does s455 tax apply to sole traders?
No. It only applies to limited companies that are classed as close companies.
Can I repay the loan after the deadline?
Yes, but the company must still pay s455 tax first and reclaim it later.
Is there a minimum loan amount?
No minimum applies for s455 tax. Even small balances can trigger it.
Does s455 apply if the loan is under £10,000?
Yes. However, separate benefit-in-kind rules apply once loans exceed £10,000.
Can I avoid s455 by declaring dividends later?
Only if the company has sufficient distributable profits and the dividends are properly documented.
What is the difference between S455 and S458?
The S455 tax forms part of the calculation of tax payable by the company. A claim to relief under Section 458 (S458) is a claim for relief against the original tax charge for the Accounting Period in which the loan was made.
