Director's Loan Account and S455 tax: what every limited company director should know

S455 tax is a Corporation Tax charge on your company, applied to outstanding director's loans not repaid within 9 months and 1 day of your company's year-end.

If you're a limited company director and you've taken money from your company that isn't salary or a dividend, it's usually treated as a director's loan. If this loan isn't repaid within a specific timeframe, your company may face a special Corporation Tax charge known as S455 tax. This tax is designed to discourage companies from effectively distributing profits to directors as loans rather than dividends or salary, and it can be significant.

What is a Director's Loan Account?

A Director's Loan Account (DLA) is essentially a record of money flowing between you and your company. If you take money out of the company that isn't salary, expenses, or a dividend, your DLA becomes 'overdrawn'. Conversely, if you put your own money into the company, or if the company owes you money for expenses, your DLA becomes 'in credit'.

An overdrawn DLA means you owe money to your company. This is a common occurrence, but it's crucial to manage it correctly to avoid tax implications for both you and your company.

Understanding S455 Tax

S455 tax is a Corporation Tax charge levied on your company if you, as a director or 'participator' (someone with a share in the company), have an outstanding loan from the company at the end of its accounting period. The tax applies if the loan is still outstanding 9 months and 1 day after the company's year-end.

The purpose of S455 tax is to prevent companies from avoiding Corporation Tax and dividend tax by providing loans to directors instead of paying out taxable dividends. The rate of S455 tax currently aligns with the higher rate of dividend tax (figures for illustration — check current rates).

How S455 Tax is Calculated

The S455 tax is calculated on the outstanding balance of the director's loan at the company's year-end. If the loan is not repaid by the 9 months and 1 day deadline, the company must pay the S455 tax on that balance.

For example, if your company's year-end is 31 March and you have an overdrawn DLA of £10,000, the company would need to pay S455 tax on this amount if it's not repaid by 1 January the following year. At the current rate of 33.75% (for loans made on or after 6 April 2022), this would be £3,375 (figures for illustration — check current rates).

Avoiding S455 Tax

The most straightforward way to avoid S455 tax is to ensure the director's loan is repaid to the company before the 9 months and 1 day deadline after the company's year-end. There are several ways this can be achieved:

  • **Cash Repayment:** You can simply pay the money back into the company's bank account.
  • **Declare a Dividend:** If your company has sufficient distributable profits, you can declare a dividend to yourself. This dividend can then be used to clear all or part of the outstanding loan. Remember, dividends are subject to personal income tax.
  • **Salary/Bonus:** If you are paid a salary or bonus, this could be used to offset the loan, though this would be subject to Pay As You Earn (PAYE) tax and National Insurance contributions.
  • **Write Off the Loan:** The company can choose to 'write off' the loan. However, this has significant tax implications for you personally, as the written-off amount will be treated as income and subject to income tax and potentially National Insurance contributions.

Reclaiming S455 Tax

The good news is that S455 tax is a temporary charge. If the director's loan is eventually repaid to the company, the company can reclaim the S455 tax paid to HMRC. You cannot reclaim the tax until 9 months and 9 days after the end of the accounting period in which the loan was repaid.

For example, if your company's year-end is 31 March 2024, and you repay the loan on 1 July 2024 (within the 2025 accounting period), you can reclaim the S455 tax from 1 January 2026 (9 months and 9 days after 31 March 2025). This means there can be a significant delay between paying the tax and reclaiming it, impacting your company's cash flow.

Impact on Company Winding Down

If your company is winding down or being liquidated, any outstanding director's loan will need to be addressed. If the loan is not repaid to the company before it ceases to trade, it will typically be treated as a distribution to you, the director. This means you will be personally liable for income tax on the outstanding balance.

Furthermore, if S455 tax was paid on that loan, the company will only be able to reclaim it once the loan is repaid. If the loan is written off or treated as a distribution during liquidation, the S455 tax may still be reclaimable by the liquidator, but the personal tax implications for you remain.

Common Mistakes to Avoid

  • **Missing the Repayment Deadline:** Failing to repay the loan or take other action (like declaring a dividend) within 9 months and 1 day of the company's year-end, leading to an avoidable S455 charge.
  • **Not Tracking the DLA:** Poor record-keeping means you don't know your current DLA balance, making it difficult to manage and plan for repayment.
  • **'Bed and Breakfasting':** Repaying a loan just before the 9-month deadline and then taking out a similar loan shortly after. HMRC has rules to prevent this, and it can lead to the S455 tax still being applied.
  • **Ignoring Personal Tax Implications:** Forgetting that writing off a loan or treating it as a distribution during liquidation creates a personal income tax liability for the director.
  • **Delaying S455 Tax Reclaims:** Not submitting the claim to HMRC promptly once the loan has been repaid, leading to unnecessary delays in your company receiving its refund.
