Overdrawn Directors’ Loan Accounts (And Section 455 Tax)

A director’s loan account is simply a means of keeping track of transactions between the director and the company of which they are a director.

Where the company is a personal or family company, the director may borrow from the company or lend money to the company.

Similarly, the director may meet the expenses of the company, or the company may pay the director’s personal bills. These transactions are recorded in the director’s loan account. Dividend or salary payments may also be credited to the account.

If the director’s account is overdrawn at the end of the company’s accounting period or at any point during the tax year, there may be tax implications to address. 

Close companies

If the company is close, as personal companies and most family companies are, there will be tax consequences for the company if the director’s account is overdrawn at the company’s year end. Broadly, a close company is one that is under the control of five or fewer participators or any number of participators if those participators are directors. A participator is someone who has an interest in the capital or income of the company.

The action that the company needs to take in respect of an overdrawn director’s loan account depends on whether the account is still overdrawn at the corporation tax due date, which is nine months and one day after the end of the accounting period.

If the loan has been repaid within this time frame, the company must disclose the loan on form CT600A when they prepare their corporation tax return, notifying HMRC of the amount that was outstanding at the end of the accounting period and the date(s) on which the repayments were made.

If the account remains overdrawn at the corporation tax due date, the company must pay section 455 tax on the outstanding loan balance along with their corporation tax. Anti-avoidance provisions exist to prevent the loan being repaid and then reborrowed in a bid to avoid the section 455 charge.

Section 455 tax

The company must pay section 455 tax on the amount by which the director’s account remains overdrawn nine months and one day after the company year end. The rate of section 455 tax is aligned with the upper dividend rate (currently 33.75%). The tax is paid with the corporation tax but crucially is not corporation tax.

Section 455 tax is a temporary tax in that it is repayable nine months and one day after the end of the accounting period in which the loan is repaid.

Clearing the loan, whether by an injection of cash, declaring a dividend or by paying a bonus, will prevent a section 455 liability from arising. However, this will not always be the best option. If the loan is cleared by a dividend or a bonus, this will trigger tax and (in the case of a bonus) National Insurance liabilities which may be greater than the section 455 tax. It may be cheaper to pay the section 455 tax and to clear the loan at a later date when it can be done more tax efficiently.

Benefit in kind charge

If the loan balance exceeds £10,000 at any time in the tax year, a tax charge will arise under the benefit in kind provisions by reference to the difference between interest on the loan at the official rate and that paid by the director (if any). The employer will also pay Class 1A National Insurance on the taxable amount.
